INTERNET ARCHITECTURE MESSAGE
THE NEW WORLD ORDER
The November 1992 IETF meeting adopted the outline of a new
organizational structure for the IAB/IETF, to accomodate continued
growth and new consituencies. This outline was documented in RFC-
1396 ["The Process for Organization of Internet Standards Working
Group (POISED)", S. Crocker, RFC-1396, January 1993]. The Board of
Trustees of the Internet Society accepted the revisions in December
1992, and transition to the new plan began.
One of the key effects of this change (known colloquially as the
"New World Order" or NWO) is to install a nominations process to
select new IAB and IESG members. IAB and IESG members will serve 2
year terms, with half of the positions on each board subject to
re-selection each year. The Internet Society Board of Trustees
will review and ratify the new IAB nominations, and the IAB will
review and ratify the new IESG nominations.
Following the November IETF meeting, a Nomination Committee was
selected by a random drawing from volunteering IETF attendees.
Jeff Case served as the chair. Roughly half of the existing members
of the IAB and IESG put their positions up for renomination; the
other half will continue to serve with a remaining term of one
year.
At the Thursday evening open plenary session of the IETF meeting in
Columbus Ohio, the Nomination Committee reported its results. The
"old" IAB was able to caucus in person and by telephone, and
approved the new IESG nominations. The ISOC Board of Trustees was
able to approve the new IAB members via email. Hence, the NWO is
now fully in effect.
THE NEW IAB
For the next year, the IAB membership will be as follows:
Bob Braden (USC/ISI)
*Elise Gerich (Merit)
Christian Huitema (INRIA)
Steve Kent (BBN)
Tony Lauck (DEC)
Barry Leiner (USRA)
*Jun Murai (WIDE)
Jon Postel (USC/ISI)
*Yakov Rekhter (IBM Research)
Cooper [Page 3]
Internet Monthly Report March 1993
*John Romkey (ELF)
*Dave Sincoskie (Bellcore)
*Mike StJohns (ARPA)
The names marked with a "*" are the new members. The IAB will
choose a chair from among its members. The chair of the IETF,
Phill Gross, sits on the IAB as an ex officio member. The IRSG
chair may also be ex officio; at present, however, it is filled by
Jon Postel, who is a regular member of the IAB.
THE NEW IESG
The new membership of the IESG is as follows:
*Phill Gross (ANS) IETF/IESG chair
*Brewster Kahle (WAIS Inc.) Applications
Erik Huizer (SURFnet) Applications
*David Crocker (SGI) Service Applications
*Allison Mankin (NRL) Transport
*Marshall Rose (Consultant) Network Management
Robert Hinden (Sun Microsystems) Routing
*Stev Knowles (FTP Software) Internet
David Piscitello (Bellcore) Internet
Joyce Reynolds (USC/ISI) User Services
*Scott Bradner (Harvard) Operational Requirements
Bernhard Stockman (SUNET/NORDUnet/EBONE NOC)
Operational Requirements
Stephen Crocker (TIS) Security
*Lyman Chapin (BBN) Standards Management
* = new or reconfirmed members
Cooper [Page 4]
Internet Monthly Report March 1993
(Note: Prior to the Nominating Committee's deliberations,
the IESG decided to divide the Transport Services Area
into the Service Applications and Transport Areas. Service
Applications will include protocols used by other
applications, and not directly by users. Examples include
DNS and NTP.)
On behalf of the IAB, the IESG, and the Internet community,
we want to express some well deserved thanks and appreciation
to the IAB and IESG members who decided not to continue:
Phil Almquist, Dave Borman, James (Chuck) Davin, and
Russ Hobby of the IESG, and Hans-Werner Braun, Vint Cerf,
Lyman Chapin, and Dan Lynch of the IAB.
Serving on the IAB and IESG is generally a volunteer job,
and as these folks know all too well, it requires a serious
investment of time. They have served us all well and will
be missed. They deserve our thanks.
IAB MEETING
The IAB held an open meeting at the IETF meeting in
Columbus, OH, on Tuesday evening March 30, 1993. A single
topic was discussed: the proposals for liaison between the
Internet Society/IETF standards process and the International
Standards Organization (ISO). The pros and cons of these
proposals were frankly and thoroughly discussed by the
IAB and some 30 attendees. No decisions were made. Cerf,
President of ISOC, will publish pertinent documentation
as RFCs.

INTERNET RESEARCH REPORTS
-------------------------
RESOURCE DISCOVERY AND DIRECTORY SERVICE
----------------------------------------
The Internet Research Task Force Research Group on Resource
Discovery and Directory Service has reformed as a small group of
researchers addressing a focused set of problems. We have
written a paper about our current directions, which is now
available by anonymous FTP from ftp.cs.colorado.edu, in the file
pub/cs/techreports/schwartz/PostScript/RD.ResearchProblems.ps.Z
(compressed PostScript) or in the file
pub/cs/techreports/schwartz/ASCII/RD.ResearchProblems.txt.Z
(compressed ASCII). Here is the title/abstract:
C. M. Bowman, P. B. Danzig and M. F. Schwartz.
Research Problems for Scalable Internet Resource
Discovery. Technical Report CU-CS-643-93, Department
of Computer Science, University of Colorado, Boulder,
Colorado, March 1993.
Abstract:
Over the past several years, a number of information
discovery and access tools have been introduced in the
Internet, including Archie, Gopher, Netfind, and WAIS.
These tools have become quite popular, and are helping
to redefine how people think about wide area network
applications. Yet, they are not well suited to supporting
the future information infrastructure, which will be
characterized by enormous data volume, rapid growth in
the user base, and burgeoning data diversity. In this
paper we indicate trends in these three dimensions, and
survey problems these trends will create for current
approaches. We then suggest several promising directions
of future resource discovery research, along with some
initial results from projects carried out by members of
the Internet Research Task Force Research Group on
Resource Discovery and Directory Service.

ANSNET/NSFNET BACKBONE ENGINEERING
----------------------------------
Network Status Summary
======================
Following a last minute problem report during AIX 3.2 testing, the
deployment of the AIX 3.2 operating system on the T3 routers is now
tentatively scheduled to begin on April 16, 1993. The first
release of AIX 3.2 will increase the on-card forwarding table
capacity to support 12,000 destinations, and the subsequent release
of AIX 3.2 software scheduled for May-June will increase the
forwarding table capacity to support 25,000 destinations, with no
hardware changes required.
ANS is now testing BGP4 in Gated and we have invited router vendors
to join us in interoperability testing. Vendors may establish TCP
sessions to a BGP4 ANSnet router over the network. We will also
support vendors that want to bring equipment to the private ANS
wide area test network. The Gated plan is described in more detail
below. No new rcp_routed routing software changes were
administered on the ANSnet during the month of March.
Development of the new higher performance RS960 T3 card proceeded
in March. This adapter (FDDI/T3) supports full HSSI bandwidth, and
will route IP datagrams at speeds in excess of 40KPPS.
Backbone Traffic and Routing Statistics
=======================================
The total inbound packet count for the network (measured using SNMP
interface counters) was 30,956,493,834 on T3 ENSS interfaces, up
14.7% from February. The total packet count into the network
(including all ENSS serial interfaces was 34,175,829,718.
As of March 31, the number of networks configured in the Merit
Policy Routing Database was 10493 for the T3 backbone. Of these,
2194 were never announced to the T3 backbone (e.g. silent nets).
The maximum number of networks announced to the T3 backbone during
the month (from samples collected every 15 minutes) was 7750, up
9.5% from February. Average announced networks on 3/31 were 7690.
Cooper [Page 13]
Internet Monthly Report March 1993
AIX 3.2 Migration Plan Status
=============================
The T3 backbone software upgrade to support the AIX 3.2 operating
system was originally scheduled to be begin on April 2nd, at 23:00
local time. However a software problem was identified and the
deployment has been delayed until April 17. The deployment is
scheduled to proceed as originally planned on April 17 instead of
April 2nd. A revised postscript file illustrating the phased
deployment at each POP CNSS and adjacent ENSS is located on
ftp.ans.net in /pub/info/aix32dpmap.ps and may be summarized as
follows:
Phase I (April 17) - Washington D.C.
Phase II (April 17) - Seattle/Denver, San Francisco/Los Angeles
Phase III (April 24) - Greensboro/Atlanta, Houston/St. Louis
Phase IV (May 1) - Hartford/New York City, Cleveland/Chicago
Growth in Destination Networks
==============================
As described in the February '93 engineering report, the interface
forwarding tables on the ANSnet routers are currently configured to
support 10K destinations. In the near term, microcode changes will
be deployed with the first AIX 3.2 build to support improved
address compression in the forwarding tables which will support 12K
destinations. A subsequent AIX 3.2 software build will be released
in the May-June timeframe that will support 25,000 destinations in
the on-card forwarding tables.
Gated, BGP4 and CIDR Progress
=============================
Dennis Ferguson is now testing BGP4 support in Gated. ANS has
extended invitations to router vendors to test BGP4
interoperability with the Gated implementation. A router running
this software is accessible on the public network and vendors may
establish TCP sessions to this machine. ANS will also support
vendors that wish to bring their BGP4 compatible equipment to test
on our wide area test network.
BGP4 within Gated will support CIDR aggregation. The kernel,
microcode and routing daemon support for CIDR is expected to reduce
the rate of growth in the number of on-card routes. ANSnet will
configure to receive and redistribute aggregated routes to other
networks that support BGP4. ANSnet will also perform proxy
aggregation for networks that are not running BGP4.
Cooper [Page 14]
Internet Monthly Report March 1993
The Gated that is being developed for ANSnet is intended to operate
as a compatible replacement for rcp_routed. Initially it will
support the ANSnet/NSFnet IGP (called SLSP, or "simple link state
protocol", in the implementation), BGP versions 2, 3 and 4 and EGP
version 2. We will also include RIP versions 1 and 2 in the build
in case this is useful at customer sites, and could include OSPF as
well for the same purpose if the routers could be made to support
local net multicasting.
Gated provides complete on-the-fly reconfigurability. That is, new
configuration files with arbitrary changes may be installed, and
Gated can be signaled to re-read them. Gated will then adjust its
running state to match the new configuration with no interruption
of already-established but unchanged routing sessions. This should
allow network reconfiguration to be done with little or no
interruption of network service. The Gated implementation of SLSP
provides compatibility with the rcp_routed IGP over point-to-point
links and adds support for broadcast subnets.
Gated's BGP, in addition to handling more modern versions of the
protocol than rcp_routed, has a number of features and enhancements
including interoperability with IBGP used by rcp_routed. A
different algorithm for resolving immediate next hops is used,
allowing the one-gateway-per-AS restriction to be relaxed. The
algorithm for importing external routes has also changed. While
rcp_routed distributes all routes it learns from an external
neighbor to all other internal neighbors (even if those routes
won't be used because a better preference route exists), Gated only
distributes external routes internally if they are equally or more
preferred than any existing route to the same destination. This
reduces the amount of state the routers maintain substantially in
the normal case, at the expense of a longer transient when a first
preference route is withdrawn.
The Gated BGP supports timers on both the incoming and outgoing
announcements. Incoming timers constrain the rate at which changes
to a neighbor's advertisements are believed and propagated into the
system. For example, setting the incoming timer to 60 seconds
means that only one change for a particular route would be
propagated every minute. This is meant to be used mostly as an
emergency means of constraining the load from announcements by
neighbors who have gone unstable. The outgoing timer delays the
propagation of changes out to neighbors. For example, setting the
outgoing timer to 10 seconds on an external peer would delay the
advertisement of internal changes for 10 seconds. This is meant to
be used to cover up internal transients which will occur when a
primary route is withdrawn but the secondary route to the same
destination has not yet been advertised internally. If the
Cooper [Page 15]
Internet Monthly Report March 1993
withdrawal-insertion occurs within the 10 second interval the
external neighbor will only see a change, not an outage.
Gated policy is substantially more flexible than rcp_routed's. We
can advertise a true default route to neighbors via BGP. While
rcp_routed can only apply outgoing policy based on neighbor AS,
Gated can in addition apply policy by network, full AS path or any
combination. Gated can apply policy to incoming IBGP, for example
allowing us to omit some networks from the forwarding tables on
some ENSS's. Aggregation policy can be configured. With BGP 4 we
can allow neighbors to advertise subnet routes to an ENSS to get
the next hop router right, but not propagate those routes into
internal routing. We will be fully free to configure multiple
gateways to the same AS, and/or to use external metrics received on
BGP connections to choose the appropriate exit for destinations
within a neighbor AS. We will be able to import and propagate a
customer's subnets when they have multiple sites using subnets of
the same network number connected to our backbone.
Gated can in principle use RIP, or static routing, or even OSPF to
obtain customer routing, giving us additional flexibility with
end-user customer configuration. While Gated currently lacks the
ability to associate an external AS with such routes to allow our
current policy methods to operate, the additional policy language
required to do this has been designed and is scheduled for
implementation.
Associated with gated is a program ("gdc") which provides an
operational interface for starting and stopping the daemon, signal
delivery and other functions. This is a better way to manipulate
Gated from shell scripts and the like since error detection is more
reliable.
Rcp_routed Routing Software Changes
===================================
There were no new changes to the rcp_routed software on the T3
network during March. There are some changes planned for April
including support for the planned migration from AIX 3.1 to AIX 3.2
software including multipath forwarding, and generation of third
party routes. Release notes for rcp_routed are available for
anonymous ftp in:
ftp.ans.net:/pub/info/t3-rcp_routed/Release-Notes
Cooper [Page 16]
Internet Monthly Report March 1993
Routing Stability Measured on the T3 Network
============================================
Internal routing stability measurements are made by monitoring
short term disconnect times (disconnects of five minutes duration
or less). During February the overall stability approached 99% (no
internal disconnects in any part of the network 99% of the time)
and all individual nodes reported 99.8% stability or better.
Overall stability in March was down to 97.5% or 99.1% excluding
instability during the configuration windows.
E206 (CERN - Geneva, Switzerland) was the most unstable node with
recurring circuit problems. E206 saw 1 hour and 29 minutes of
instability outside of the configuration window. E205 and C51 were
used as test sites for AIX 3.2 deployment before becoming full
production nodes. These saw about 1 hour each of instability
outside of the configuration windows. The remaining 84 nodes
reported less than 21 minutes of instability (99.96% stability or
better) excluding the configuration windows with 61 reporting
better than 99.99% stability (under 4:48).
When the configuration window is included, there was over 18 hours
of instability (where any one node was disconnected). Several new
nodes were brought on line this month. This tends to lengthen
configuration runs. Some circuit testing at E206 was performed
during the configuration window. There were some router card
failures which resulted in card replacements during the
configuration window. A few nodes were upgraded to AIX 3.2. Some
testing was done on AIX 3.2 at new installations prior to going
into full production. Three production nodes and one new
installation reported 2 hours to 3:43 of instability (99.75-99.5%
stability). 18 nodes reported 1-2 hours of instability. The
remaining 68 nodes reported less than 1 hour of instability during
the configuration runs (99.86% stable or better). Reducing the
impact of the configuration runs is a near term goal.
External route flaps were measured by collecting IBGP updates with
the unreachable attribute at an internal router between Feb 28
19:05:14 UTC and Mar 31 20:38:21 UTC. During this period 200,041
updates were received from 615 distinct AS paths. These updates
contained 818,812 network numbers (about 4 networks per update on
average). The were 4,048 distinct network numbers (an average of
202 unreachables per flapping network number). The most unstable
network flapped 4,786 times (once every 9.3 minutes on average over
the course of one month). On average 269 updates with unreachables
were received per hour, withdrawing an average of about 1,100 route
per hour. There were 17% fewer updates, and 38% more routes
withdrawn than in February. The 60% increase in the number of
Cooper [Page 17]
Internet Monthly Report March 1993
routes per update may indicate less flapping by end systems, and
more flapping by transit systems compared with the February
results.
SNMP Public Community Views
===========================
ANS has always provided a read-only SNMP community on ENSS and
selected CNSS routers to ANS customers and NSFNET regional techs.
This SNMP access provides a useful window into technical aspects of
ANSNet, allows customers to better manage their external
connectivity and is an invaluable aid when debugging connectivity
problems.
Until recently we permitted read-only access to the full set of
MIBs available on each router. For security and performance
reasons we are now restricting snmp lookups to the following MIB-
II objects:
System, interfaces, at, ipForwarding, ipDefaultTTL, ipInReceives,
ipInHdrErrors, ipInAddrErrors, ipForwDatagrams,
ipInUnknownProtos, ipInDiscards, ipInDelivers, ipOutRequests,
ipOutDiscards, ipOutNoRoutes, ipReasmTimeout, ipReasmReqds,
ipReasmOKs, ipReasmFails, ipFragOKs, ipFragFails,
ipFragCreates, ipAddrTable, ipNetToMediaTable,
ipRoutingDiscards, icmp, tcp, udp, egp, transmission, snmp,
enterprises.25
As far as we have been able to tell, this restriction should not
affect any SNMP polling currently being done on the network.
T3 Network Performance for Source Route Optioned Packets
========================================================
Some tests involving switching of loose source record route (LSRR)
optioned packets were performed on the T3 network to verify network
performance in the presence of Mbone traffic (thanks to PSC).
Multiple streams of 7.8Mb/s each were sustained between PSC and
Chicago for a bi-directional total of 23.5Mb/s of LSRR packet load
without any packet drops or other problems.

Scaleability
Work continued on enhancements to the flow-level network simulator.
Some code redesign was done to make the software more modular and
to better support planned features. The delay model has been
completed. Work is currently in progress on statistics collection
and display. A general statistics output file format is being
defined to minimize the size of collected data files, which may be
quite large for long-running simulations.
Also, a candidate set of algorithm investigations has been
proposed, and recommendations determined for the next phase of
algorithm research.
InterDomain Policy Routing (IDPR)
We have been making the final tests of the IDPR gated software in
preparation for the Internet pilot demonstration. The machines
that will act as policy gateways for the transit domains NSFnet,
NSInet, and TWBnet will be shipped out in early April. At the
conclusion of the pilot, we will generate an informational RFC
describing the results.
We are also in the process of updating the configuration document
for IDPR and expect to have a new draft by the end of May.
Real-time Multicast Communications and Applications
We began investigating hooking up ISI's MMCC conferencing
application as a source and destination that can be accessed via
BBN's videoserver. We are currently awaiting a new version of this
application which will provide a better interface for this work.
Cooper [Page 21]
Internet Monthly Report March 1993
We began work on extending the XIO protocol to support multicast
video and multi-resolution video. The XIO protocol is the protocol
used by a software switch at the video server to communicate with a
workstation running a video application. Just as an analog
hardware switch sets up analog communications between a source and
destination, the software switch, using the XIO protocol sets up
digital communications between a source and a destination. The
video server will support transmission of video to a multicast
address, allowing multiple workstations to simultaneously view the
same video. The video server will also support transmission of
multi-resolution video, enabling workstations to receive video at a
bandwidth supported by the network connections between the
workstation and the server. With this capability, two
workstations, one on the end of a high bandwidth line and the other
at the end of a low bandwidth line, will be able to simultaneously
receive the same video at two different resolutions.
Paul Milazzo participated in a panel session entitled "Multimedia
Internetworks" at InterOp '93 in Washington. He gave a talk
entitled "Video over IP Internetworks." Paul also attended the
IETF meetings in Columbus late in the month and participated in the
Audio/Video Transport (AVT) working group meetings. We are using
an earlier version of the AVT protocol in the video server; we are
keeping abreast of developments on the protocol and updating our
implementation as needed.
On the protocol and communications front, our work this month was
concentrated on extending the design of the four service concepts
(anycasting, multi-level flows, shared streams, and resource
coordination objects). A number of areas were found where the
services could be made more general. Considerable effort was spent
to identify ways of making this work more widely available, and
improving integration with other internet research.
ANYCASTING -- The anycasting service has been implemented and is
operational. It is compatible with existing routers and routing
protocols, though efficient address-space utilization requires
routers to support mask-based routing protocols such as OSPF. The
current implementation works on SunOS and uses a simple extension
of the BSD networking code. The implementation is easily portable
to other BSD-based systems, and the technique should be
straightforward to implement on other platforms.
MULTI-LEVEL FLOWS -- We are planning to augment the IP multicast
routing implementation, mrouted, to support multi-level flows.
This will include upward-compatible extensions to IGMP to identify
which sub-flows the receiver desires. A design goal is to support
interoperation with unmodified IP multicast routers, though optimal
Cooper [Page 22]
Internet Monthly Report March 1993
delivery of sub-flows may not occur when unmodified routers are
involved.
SHARED STREAMS -- This service is an extension of resource
reservation mechanisms such as Fair Share and RSVP. It permits
multiple flows to request to share a single resource reservation,
which allows distributed applications to make use of statistical
multiplexing. We are starting an implementation of shared streams
based on the Fair Share code, and are planning to use resource
coordination objects (see below) to describe the flows.
RESOURCE COORDINATION OBJECTS -- RCOs are a general technique for
distributed applications to communicate information about
aggregates of network-related resources among hosts and network
nodes. They can be used to support both session-layer services and
network-layer services, and can be used to coordinate auxiliary
information about flows with network routing. There are a wide
variety of potential uses for RCOs, including distributed session
management, network resource reservation, multicast access control,
and intelligent resource preemption. We have just started work on
designing a basic infrastructure for RCOs, including a variety of
propagation paradigms.

MULTIMEDIA CONFERENCING
At the Columbus IETF meeting, we chaired two teleconferencing-
related groups. The Audio/Video Transport Working Group is nearing
completion in the specification of an experimental real-time
transport protocol. A second group on Conferencing Control met as
a BOF to discuss the requirements of a session protocol for
multiway collaborations, and particularly to focus on a suitable
scope for this problem to establish a charter and a working group.
The intent is to specify a protocol to support loose- and tight-
control conference styles.
As an example of how such a session protocol might interact with
the already popular tools such as PARC's nv and LBL's vat, we
demonstrated at the IETF an X-based version of the MMCC conference
control tool. MMCC takes a tightly-controlled approach to session
management in that it explicitly shares full session-related
information among all the participants. In the demonstration, we
used MMCC to invite a specific set of participants (vs having a
wide-open session), to distribute multicast addresses and a shared
encryption key among those participants, and to initiate as well as
tear down sessions comprised of some selection of underlying tools.
Since MMCC stays "in the loop" after session initiation, we expect
it in the future to provide a channel for negotiation of quality of
service and configuration parameters as they may change during the
session. We intend soon to release MMCC for more widespread use.
The Columbus IETF marked the fourth live multicast of audio and
video. A memo on "How to do an IETF A/V multicast" was written to
help the organizers of the Columbus and future IETFs to set up the
necessary equipment. Also, just before the meeting, Van Jacobson
implemented IP encapsulation for multicast tunnels; with Steve
Deering, we worked to test and distribute that code as widely as
possible since it makes a big performance improvement.
The paper, "The Impact of Scaling on a Multimedia Connection
Architecture", was completed this month, and will appear in the
Journal of Multimedia Systems. A shorter version appeared in the
3rd International Workshop on Networking and Operating System
Support for Digital Audio and Video, San Diego, CA (Nov 1992).

JANET
-----
March has been a relatively quiet month in terms of changes to
JANET. This has been due mainly to delays in receiving router
equipment necessary to carry out the upgrades described in the last
monthly report. It would seem that demand exceeds supply for cisco
AGS+/4 components, and particular difficulty has been experienced
in getting the HSSI interfaces necessary to implement the 34 Mbit/s
backbone for SuperJANET. Delivery dates have been missed although
revised dates suggest that it will be possible to bring this
backbone up in mid April.
On 23-25 March the JANET community had its annual Networkshop
conference at the University of Birmingham. Traditionally this is a
time when new ideas for the next year are discussed. One of the
topics debated this year was whether there should be a migration of
the JANET network from an X.25 base to an IP base. (Currently the
network is based on X.25, with IP encapsulated on top of this.
However, the strong growth in use of IP has meant that over 60% of
the traffic on the network is in fact encapsulated IP.)
Operationally it makes sense to move to less use of IP encapsulated
over X.25 in the backbone, but the main question was whether some
sites would prefer to use only IP in connecting to JANET, and
forsake X.25. The consensus was that this should happen relatively
quickly, to support the rapid growth in use of IP-based
applications at sites, although there will still be a significant
need to support X.25-based applications for some time at many
sites.
We are therefore now studying the best means of satisfying this
demand -- at present the most feasible solution seems to be to
migrate JANET to an IP network and to run a X.25 network on top of
this by encapsulation. The X.25 network would be relatively large
at the outset but, if the requirements expressed by site
representatives at Networkshop turn out to be accurate, this should
drop off fairly rapidly.
The total IP traffic switched across JANET in March was
approximately 1150 Gigabyte. Of this approximately 210 Gigabyte
passed through the UK/US Fat-pipe, and approximately 115 Gigabyte
to and from EBONE. The number of hosts attached can be measured,
to first order, by the size of the ac.uk domain. As of end March it
contained 54338 distinct hosts in 296 subdomains. (This was an
increase of 3510 hosts and represents approximately 90% of the uk
domain.)

Announcement -- Transition from NNSC to the New InterNIC Team
==============================================================
On April 1, 1993, the NSF Network Service Center (NNSC) began to
phase out its services following the final award of the long-
awaited "Network Information Services Manager(s) for NSFNET and the
NREN". The services formerly provided by the NNSC are being
transferred to a new team made up of three separate organizations,
collectively known as the InterNIC (the Internet Network
Information Center).
* Network Solutions (NSI), has provided registration for the
NSFNET since January 1992, and continues to perform all
REGISTRATION SERVICES on host RS.InterNIC.NET.
* AT&T will provide expanded DIRECTORY AND DATABASE SERVICES
on host DS.InterNIC.NET .
* General Atomics, which now operates CERFnet and the San
Diego Supercomputer Center, provides a Reference Desk and
general INFORMATION SERVICES on host IS.InterNIC.NET .
Cooper [Page 30]
Internet Monthly Report March 1993
This award expands the scope of the services which have previously
been supplied by several organizations, including the NSF Network
Service Center (NNSC). The NNSC is assisting the combined Network
Information Services Managers in this transition.

MERIT/NSFNET ENGINEERING
------------------------
Significant activities for March included transition of production
NSFNET configuration services to the new Informix-based Policy Routing
Database; IETF activities (including NSFNET connectivity to the hotel
via OARnet); and demonstration of "TUBA" applications over the OSI
CLNP infrastructure in the Internet. Projects involving the Merit IE
group include development of and experimentation with Route Servers
and enhancements to the PRDB to allow configuration of CIDR route
aggregation for NSFNET. Status reports on the Inter-Domain Routing
Protocol development project, and the Shared Whois Project, are also
included here.
Policy Routing Database Changes
-------------------------------
In March the Merit NSFNET-admin staff completed the cutover to the
new, Informix-based, Policy Routing Database system. Design goals for
the new system include flexibility to make changes for future routing
database needs, though the initial deployment goal was to make the
system look as similar as possible to the old system to allow smooth
transition for the configuration operations staff. The new system
includes enhancements to allow batch updates to be more efficient, and
streamlines the configuration file and report generation process.
The new system is accessed using a generalized client-server
interface, with clients ported to several unix systems (currently they
are running on the Sun and IBM RS/6000 systems). The "show" clients
for querying the database have been made available for anonymous ftp
from merit.edu:pub/src/prdbshow.tar.Z.
Projects underway for further development of the system include
generation of configuration files for Gated (the routing daemon which
will be deployed on the ANS routers), support of route aggregation for
Classless Inter-Domain Routing (CIDR), configuration support for
planned changes to the ANSnet link to CERN in Switzerland, and support
for configuration of route servers based on Gated.
Internet Engineering Task Force (IETF) Activities
During the IETF in Columbus, Ohio from March 29 - April 2, ANS
provided connectivity to the Hyatt Regency Columbus workstation room
to NSFNET. To support the TUBA demonstration of TCP/UDP transport over
the OSI CLNP infrastructure, an RT workstation was deployed in
Columbus to provide encapsulation for OSI connectivity.
Cooper [Page 33]
Internet Monthly Report March 1993
During the BGP Deployment working group meeting, an Internet Draft on
support of aggregation in the NSFNET was presented. Merit will support
configuration of the backbone to support acceptance of aggregates from
midlevel networks, announcement of such aggregates to midlevels, and
aggregation on behalf of midlevels whose routers are not configured to
support BGP-4. Merit will also implement an Aggregate Registry
function which will allow registration by autonomous system peers of
aggregations which will be announced between AS neighbors.
Discussions of the TUBA approach to the "IP Next Generation" problem
took place during the IETF Monday plenary session as well as in two
working group sessions. TUBA implementations for six different
platforms are underway. Discussion topics included dynamic host NSAP
address assignment, mobile hosts, the routing and addressing plan, and
TUBA transition strategies. Implementation status as well as
implementation and demonstration targets were discussed and agreed on
as short term goals. An application document detailing changes needed
to application protocols and implementations for TUBA will be
written--this document will be useful for the other IPNG working
groups as well.
At the Network OSI Operations working group meeting, one of the topics
discussed was formalization of CLNP operations. There was a call for
24-hour monitoring of OSI routers and hosts. Another goal is policy
routing database support for dynamic OSI routing protocols (intra- and
inter-domain). Merit agreed to implement an OSI-ping process which
will send e-mail for machines which do not respond via CLNP. We will
also make the EON configuration file which maps NSAP prefixes to IP
addresses for encapsulation available under merit.edu:pub/noop.
The IDRP-for-IP working group also met at this IETF. Internet draft
documents discussed at this meeting included an IDRP Family document,
IDRP-for-IP, IDRP MIB and IDRP-OSPF interactions.
IDRP Implementation Status
--------------------------
The IDRP implementation within Gated is underway and further progress
was made this month. CLNP and IP routes were exchanged between routers
using IDRP in Merit's test lab. A demonstration of the IDRP
implementation is scheduled for April for the Mitre and FAA groups
working on the Aeronautical Telecommunication Network. Deployment of
IDRP on the ANS backbone is expected in July of this year.
Cooper [Page 34]
Internet Monthly Report March 1993
Shared Whois Project
--------------------
The project to share data on IP networks and related routing and
contact information made progress this month. Merit and RIPE are now
regularly sharing data using an agreed-upon "transfer syntax". The
InterNIC staff at Network Solutions are working on this project as
well.
Another aspect of this project is the inclusion of NSFNET routing
information in the X.500 Directory. Merit met with the InterNIC NS and
AT&T staff and agreed on a schema to allow the InterNIC X.500 whois
network entries to point to routing entries at Merit. We expect to
have this information online in May.

NSFNET/INFORMATION SERVICES
---------------------------
The Merit Network Information Center (NIC) Services host computer,
nic.merit.edu, contains a wide array of information about the
Internet, NSFNET, and MichNet and is accessible via Anonymous FTP,
electronic mail, Gopher, and WAIS. The directory
/introducing.the.internet was developed in cooperation with the
Internet Engineering Task Force (IETF) User Documents Working Group
and is intended to provide recent information resources which will
help the network novice become familiar with the Internet, its
associated networks, resources and protocols. New to this directory
is John December's "Information Sources: the Internet and
Computer-Mediated Communication," release 2.30, 15 March 1993. Also
of note in the directory /nsfnet/statistics are reports of NSFNET
statistics, as they are available, at monthly intervals. The primary
tools used to collect the statistics are the SNMP and NNStat software
packages. Monthly reports are in sub-directories according to the
year in which the data was collected. Other files available in this
directory are:
history.bytes Growth in traffic on the NSFNET as measured in
bytes. Byte traffic measurements are available
as of March 1991, and represent the combined byte
traffic on the T1 and T3 infrastructures.
history.netcount Growth as reflected in the number of domestic and
foreign networks having announcement to the
NSFNET infrastructures.
Cooper [Page 35]
Internet Monthly Report March 1993
history.packets Growth in traffic on the NSFNET as measured in
packets. As of January 1991, the packet traffic
measurements represent the combined traffic on
the T1 and T3 infrastructures.
history.ports Distribution, by percentage, of most common uses.
nets.by.country Distribution, by country, of networks announced
by NSFNET.
Another in the successful series of Merit Networking Seminars was
held in San Francisco, March 15 and 16. BARRNET hosted "Making
Your Internet Connection Count: Technology, Tools and Resources,"
and provided Internet connectivity to the demonstration room at the
San Francisco Airport Hilton. Apple Computer, Inc. donated
Macintosh computers for use at the conference, enabling the 82
attendees to use e-mail and experiment with the Internet resources
and tools discussed. Alan Emtage, co-creator of archie; Mark
McCahill, Gopher project leader; and George Brett, National WAIS
Clearinghouse; discussed "Information Delivery on the Internet--
Present and Future." Featured speakers included Tom Grundner,
creator of the Cleveland Freenet; Perry Samson, U-M Weather
Underground; and Paul Evan Peters, Executive Director, Coalition
for Networked Information.
Ellen Hoffman, manager of Merit Information Services, and Laura
Kelleher, Merit Information Services, attended the meeting of the
Coalition for Networked Information (CNI) which convened in San
Francisco March 20-23. Doug VanHouweling, Vice Provost for
Information Technology Division at the University of Michigan,
spoke on the future of national networking as a representative of
EDUCOM.
IETF in Columbus (OH) was well attended by Merit Internet
Engineering and Merit Information Services staff: chairing working
groups were Sue Hares, NOOPS; Ellen Hoffman, UserDoc; Pat Smith,
NISI; Chris Weider, IIIR and IDS. Mark Davis-Craig chaired the BOF
"Low-Cost IP Hardware Wish-List," which made recommendations to
FARNET on an RFI to vendors, an inventory of existing solutions,
and a matrix of costs and responsibilities for buyers. Susan R.
Harris, Susan M. Horvath, Dale Johnson, Sheri Repucci and Steven J.
Richardson participated in several sessions; Mark Knopper, manager
of Merit Internet Engineering, discussed the status of the NSFNET
in the plenary session. Elise Gerich, Merit Internet Engineering
and recently elected to the IAB, attended a meeting of an IEPG
subgroup to discuss the Global Internet Exchange (GIX). Gerich
also traveled to Moscow, Russia, to participate in discussions
regarding the creation of a Russian Space Science Internet.

SDSC (SAN DIEGO SUPERCOMPUTER CENTER)
-------------------------------------
SDSC Network Activities
=======================
The new CSUnet router has arrived and been installed at SDSC.
We have registered new domains for the metacenter effort -
metacenter.edu and metacenter.dni.us. Additionally, our two
network test probes for NCEnet research arrived and our being
tested.
We adjusted the MTU on our Cray from 32k to 16k. This will serve
as a work around to a bug in our Emulex terminal servers which can
not handle larger values.
SDSC hosted the first Torrey Mesa MAN planning meeting during
March. A second is planned for April.
And, as it has been for the last several months, the building fiber
install moves forward.

UNIVERSITY OF DELAWARE
----------------------
1. We have completed changes in both the DEC Ultrix 4.2a and Sun
SunOS 4.1.1 Unix kernels to improve timekeeping quality with
the Network Time Protocol. In the case of the DECstation
5000/240, they reduce the jitter from almost 4 milliseconds to
about 20 microseconds. In the case of the Sun 4/65, they
reduce the jitter in half to about 40 microseconds. Since the
phase-lock loop is now in the kernel, stability is improved as
well to about one part-per-million. This allows the interval
between network updates to be increased, as well as reduces
the time to converge following reboot.
2. The current distribution of the Network Time Protocol Version
3 has been augmented with several new timecode receiver
drivers, including two for the Global Positioning Service
(GPS) and one each for the German DCF77 system and U.S. Navy
Omega system. With these drivers, redundant NTP primary
(stratum 1) service is potentially available worldwide. Ports
for several new Unix workstations, including DEC Alpha (OSF/1)
and Sun SysV (Solaris), are near completion. Improved
facilities to capture precision signals generated by some
timecode receivers have resulted in accuracy improvements to
the order of 40 microseconds with fast workstations and
networks.
3. Through the kindness of the U.S. Coast Guard, we now have a
cesium clock onsite, as well as a motley collection of GPS,
WWV, WWVB, CHU and LORAN-C timing equipment. Efforts lasting
over a year have not been able to identify the source of
interference that disrupts WWVB reception in our area, so we
have switched the master clock for our local nets and DARTnet
to a GPS receiver. A second GPS receiver at Lawrence Berkeley
Laboratories provides backup timing for DARTnet.
4. We are collaborating with Judah Levine at National Institutes
of Science and Technology, Boulder, CO, in an experimental
evaluation of the NIST Automatic Computer Time Service. The
ACTS service is accessed via telephone modem with automatic
correction for propagation delay. One of our hosts is set up
to dial the ACTS service on a periodic basis, with performance
measured using NTP and our master clock.

WISCNET
-------
The DDS links connecting UW-Parkside and the Medical College
of Wisconsin to UW-Milwaukee were replaced with SMDS service.
We had considerable initial difficulties with the provider's
switch shutting down the lines but these were cleared up by
new software from the switch manufacturer.
WiscNet now has two T1 points of connection to CICNet. A new
one from UW-Milwaukee to CICNet at Downer's Grove and another
at UW-Madison. WiscNet and CICNet worked jointly to route
Milwaukee area through the UW-Milwaukee connection, other
traffic flows through the UW-Madison connection.
The WiscNet Board of Directors held a planning retreat 3/25/93
through 3/26/93.
A user conference will be held on 4/28 and 4/29 at UW-Stevens
Point. The conference concentrates on locating Internet
resources with the theme 'where in the world is...?' The
keynote speaker is Connie Stout, Program Director, Texas
Education Commission. More information on request.
