INTERNET ENGINEERING REPORTS
----------------------------
1. The next IETF meeting is scheduled for Columbus, Ohio from March
29th through April 2, 1993 (yes, this does mean that the IESG
Open Plenary will be held on April first). The meeting is being
co-hosted by OARNet and The Ohio State University. There will be
a registration reception on Sunday, March 28. Logistic and
registration information will be forthcoming from the IETF
Secretariat.
The 27th meeting of the IETF, scheduled for July of 1993, will
be held in Amsterdam, The Netherlands, and will be co-hosted by
SURFnet and RARE. This will be the first time an IETF meeting
has been held outside of North America. Negotiations are still
in progress for the meeting facilities and catering
arrangements, and there will be a higher fee for this meeting
(estimated to be at least $200). More information will be
provided as it becomes available.
2. After reviewing the increased intertwining of OSI activities
with the work in the other areas, the IESG has decided to adjust
the area boundaries to integrate most of the current OSI
activities with the Applications and Internet areas. Dave
Piscitello will join Phil Almquist and Stev Knowles as a co-
director of the Internet Area, and Erik Huizer will join Russ
Hobby as a co-director of the Applications Area. All of the
current work in progress is continuting unchanged.

INTERNET PROJECTS
-----------------
BOLT BERANEK AND NEWMAN INC.
----------------------------
InterDomain Policy Routing (IDPR)
---------------------------------
During the past couple of months, we have been preparing the gated
software for the IDPR pilot Internet installation planned for early
1993. This pilot installation involves three transit domains
(including NSF and NASA) and four source domains. Transit policies
will be set by the participating transit domains.
During the pilot installation, only that traffic designated as IDPR
will be handled by IDPR. Regular production traffic traversing the
participating domains will not be affected by the pilot
installation. Moreover, none of the existing routers within any of
the participating domains requires IDPR software. Sun workstations
will act as policy gateways for the participating domains. Each
source domain will have at least one policy gateway associated with
it, and each transit domain will have two policy gateways
associated with it.
The pilot installation will have both an experimentation component
(reconfiguration of policies and observation of the resulting
effect on the IDPR traffic) and a field trial component (allowing
IDPR to run uninterrupted for several weeks). At the conclusion of
the pilot, we will be publishing the results as an Internet Draft.
Preparation for the pilot involves modifying the gated software in
three ways:
(1) Add support for source policies, so that sources can request
routes with specific characteristics and so that route servers
can generate such routes.
(2) Permit multiple policy gateways to reside in a single router.
The policy gateways acting on behalf of the three transit
domains will reside on the FIXes. There will be one router per
FIX, which will act as a set of policy gateways on behalf of
the three participating transit domains.
(3) Add the ability to collect selected protocol trace information
for post-processing. The pilot installation will be in place
for several weeks, and hence we need to be able to accurately
track its performance.
Cooper [Page 8]
Internet Monthly Report December 1992
BBN and SRI together have already added the source policy
capabilities to the gated software. We, at BBN, have successfully
tested the new source policy software on a set of workstations in
our test lab. Currently, we are in the process of making the
necessary software modifications to permit multiple policy gateways
to coexist in a single router.
Scaleability Project (aka Project 10^4)
---------------------------------------
Over the past months, BBN has been examining the problems and
possible solutions associated with large-scale geographically-
distributed real-time simulations. To date, such simulations have
been limited to approximately 1000 simulated entities by the
network load imposed by the current method of data distribution to
simulation sites, which involves all traffic being sent to every
participant. The simulation community wishes to handle 10^4 entity
real-time simulations by 1995, and 10^5 entity simulations by the
year 2000. The gap between current practice and these goals led to
the creation of this project.
The project is developing a toolset for investigating application
and networking behaviors, and for evaluating new algorithms and
techniques for better utilizing the long-haul network. The toolset
includes a simulation simulator, which uses a modified SAF (Semi-
Autonomous Forces) simulator to generate simulation traffic
representing 10,000 entities at a variety of sites, over the course
of a several-hour exercise; a "scaler" component, which serves as a
test harness to evaluate various compression and data distribution
techniques; and a modular, medium-resolution, flow-level network
simulator, which allows evaluation of various multicast
technologies, network topologies, and routing and congestion
algortihms, as well as the evaluation of the effects of application
scaling algorithms on network traffic and performance.
Several successful demos of the preliminary scaleability toolset
were given during November, using a network topology based on the
current Defense Simulation Internet (DSInet), and a hypothetical
future DSI based on T3 backbones.

CONCERT
-------
MCNC held it's second Packet Video Workshop on December 9th and
10th. This was a workshop intended for those involved with Packet
Video from product development, planning, installation, management
and analysis points of view. Over 125 representatives of industry,
government, and research institutions from around the Internet
attended. The workshop was sponsored by the Packet Video
Consortium, the National Science Foundation and MCNC. The workshop
was broadcast over the Internet using IVS and NV for video and VAT
for audio.
CONCERT staff members participated with staff from the NSF, LBL,
ISI and Xerox PARC in giving a demonstration to a representative of
the Clinton-Gore transition team showing the current capabilities
of videoconferencing over the Internet. A multipoint
videoconference among the above groups was held using VAT and NV.
by Tom Sandoski <tom@concert.net>
CSUNET (THE CALIFORNIA STATE UNIVERSITY NETWORK)
-----------------------------------------------
In November, the California State University Network (CSUNET)
agreed with the San Diego SuperComputer Center Network (SDSCNET) to
install a T-1 multiplexer at the SDSC center to enable the
institutions to share SDSC's nationwide supercomputer center
videoconferencing channel. SDSCNET has a 384 Kbps fractional T-1
from MCNC in North Carolina to San Diego.
The existing T-1 between CSUNET and SDSCNET will carry both video
and TCP/IP Internet bound traffic. As part of the agreement,
CSUNET will be installing a gateway at SDSCNET to peer with the
ENSS at San Diego.
In December, CSUNET improved its dialup CSUNET access ports (CAPS)
software. The new features allow better call monitoring and
control. The gateway from X.25 to TELNET has also been upgraded
for better security and call tracking.
Because of the improvements to CAPS, CSUNET has connected AppleTalk
Remote Access (ARA) servers which are available for use by CSU
Chancellor's office staff. CSU campuses are investigating
installation of similar services to provide their faculty with
remote access at their homes.
Cooper [Page 10]
Internet Monthly Report December 1992
A new SLIP service using the CAPS dialup service has been installed
which allows remote IP access from any CSU campus CAPS dialup pool.
The service uses SLIP software on CSUNET's Telematics X.25 network
to route the SLIP connection to an X.25/IP router.

MULTIMEDIA CONFERENCING
Our original implementation of the multimedia conference control
program (MMCC) was under SunView, but conversion to X windows is a
practical requirement for continued development and use. We have
made a preliminary conversion to XView this month except for a few
pieces of functionality that don't convert directly.
Slides and annotations on the topic of "A Software Architecture for
Packet Teleconferencing" were prepared for the 2nd Packet Video
Workshop at MCNC, Research Triangle Park, NC, Dec 9-10, 1992; the
presentation itself was given by Fengmin Gong of MCNC, with ISIers
listening in and watching over the MBONE.

NORTHWESTNET
------------
NorthWestNet is pleased to be a partner with the Pacific Northwest
Region of the National Network of Libraries of Medicine in the
implementation of a project recently funded by the National Library
of Medicine. The project is titled "From Bench to Bedside:
Research and Testing of Internet Resources and Connections in
Community Hospital Libraries."
The project has three major components: bringing Internet
connectivity to seven participating community hospital libraries
located in Alaska, Idaho, Montana, Oregon, and Washington;
exploring network-based access to anatomical images; and providing
a directory of DNA diagnostic laboratory directory information to
clinicians in these communities.
The goal of the project is to research the technical, financial,
and user support models of implementing Internet access and
services in the health care community. Participants at the
community hospitals will include librarians, network support staff,
researchers, and clinicians. The project will extend through the
spring of 1994.

NSFNET/ANSNET BACKBONE ENGINEERING
----------------------------------
Network Status Summary
======================
Following the T1 backbone disconnection on Dec. 2nd, the T3 is now
supporting all NSFNET services. A 2nd ethernet interface was
installed in ENSS136 to support interim connectivity to the MAE-
East facility. The former T1 backbone class B address (129.140)
was returned to the NIC. CA*Net peer router hardware
reconfigurations will be completed in January to allow direct T3
network peering. A plan has been developed to dismantle and remove
the RT routers at regional sites.
Following the software changes resulting from instabilities
observed during the MBONE multicasts in November, the T3 backbone
routing stability has been very good in December. Daily reports
are now generated on internal and external peer network routing
stability.
Seven new RS960 FDDI interfaces were installed on ENSS nodes in
December. Reliability and performance of the FDDI hardware has
been very good.
Backbone Traffic and Routing Statistics
=======================================
The total inbound packet count for the T3 Backbone (measured using
SNMP interface counters) was 22,009,352,089 up 5.0% from November.
As of December 31, the number of networks configured in the NSFNET
Policy Routing Database was 8561 for the T3 backbone. Of these,
1760 were never announced to the T3 backbone. The maximum number
of networks announced to the T3 backbone during the month (from
samples collected every 15 minutes) was 6187. Average announced
networks on 12/31 were 6154.
Previously when the T1 Backbone was operational the overall average
number of networks announced via the primary configured AS path was
around 88%. Since the T1 Backbone was dismantled this average has
gone to around 95%. Graphs of this information are available for
anonymous ftp on merit.edu, in pub/nsfnet/offnet, as postscript
files.
Cooper [Page 17]
Internet Monthly Report December 1992
Routing Software and Stability on the T3 Network
================================================
Higher than usual MBONE activity in November resulted in exterior
routing instabilities and routing instability internal to ANSnet.
Following the immediate corrective actions that were taken in
November, a number of software changes were made in December.
Changes to the RS960 microcode and efficiency improvements in the
routing software have resulted in improved ANSnet internal routing
stability (regardless of the presence of external route flapping).
The MBONE participants have made changes to route MBONE traffic
over the T3 backbone whenever possible, resulting in improved
routing stability within certain US regional networks.
Detailed reports of internal ANSnet and external peer network
routing instabilities are now generated on a daily basis. The
ANSnet internal report attempts to summarize outages based on
number and duration of the IBGP disconnects. The program that
generates this report looks at IBGP disconnects in a short time
window. It tries to assign the outage to the node with the most
disconnects, and then eliminate all disconnects on other machines
associated with that router. If after eliminating disconnects
related to the router assigned to the outage, more disconnects
remain in the same time window, the process is repeated, assigning
secondary and tertiary responsibility for the outage and so on
until all disconnects are accounted for. The time window is
extended to cover all disconnects that are not separated by more
than a five minute period in which there is no change to internal
routing in the network.
Using this method, data sufficient to generate reports on internal
ANSnet routing stability has been collected continuously since
October reported 99.0% internal routing stability (no changes to
internal routing). These two nodes reported 98.9% stability,
mostly due to a problem early in December. Most nodes reported
99.0% to 99.5% stability. Two reported better than 99.5%
stability. The vast majority of this instability is due to the
regular configuration updates and scheduled maintenance. With the
dismantling of the T1 backbone, activities are underway to reduce
the duration of time required to process the bi-weekly router
configuration runs, and scheduled maintenance.
Similar data on external routing stability has been collected
continuously since December '92. The external routing stability
reports will record an external route which is withdrawn from the
ANSnet due to: (1) an EGP route timing out (not being advertised by
an external peer), (2) an explicit BGP unreachable received from an
external peer, (3) the loss of an external EGP or BGP session that
Cooper [Page 18]
Internet Monthly Report December 1992
is not accompanied by loss of internal IBGP sessions. Excluded are
the following cases: (1) we do not observe changes in the next hop
at the ENSS, (2) the route is replaced by another route on the same
ENSS, (3) a route is lost and backed up by another route on the
same ENSS, (4) connectivity is lost due to ANSnet internal problems
(e.g. configuration runs or other). Some of this data has already
been shared with specific regional networks to get feedback. In
January, these reports will be fully automated and distributed to
peer networks which are advertising networks that are withdrawing
reachability excessively (e.g. exhibiting great instability).
After the recent FIX-East reconfiguration, a bug in rcp_routed was
observed that would result in an ENSS installing a route locally
that had previously been advertsized by a peer, where the route was
rejected on the ENSS due to policy constraints (no NACR request).
Such a route would incorrectly be installed on the ENSS (but not
advertised) when the destination becomes completely unreachable.
On ENSS136, the existence of multiple peers coupled with the use of
default routing by some peers could form a routing loop when this
occurs. This problem in the rcp_routed software has been corrected
and is deployed on ENSS136. Deployment of the same changes across
the rest of the ANSnet is scheduled for early January.
Another planned change to rcp_routed in January involves fixing the
metric_in function for EGP. This will allow regional peer routers
to be able to have an EGP session with the same ENSS on two
different interfaces (FDDI and ethernet) and prefer the FDDI via
metrics.
RS960 FDDI Deployment Status
============================
During the month of December, we installed RS960 FDDI adapters at
the following 7 locations: Boston (E134), Argonne (E130), FIX-E
(E145), Houston (E139), Ithaca (E133), FIX-W (E144), Seattle
(E143).
Domain Name Service for ANSnet
==============================
In December, ANS made two adjustments to the DNS administration of
the ANS backbone. First, the "t3.nsf.net" domain was renamed to
"t3.ans.net", and second, we added geographical designators to all
CNSS nodes. ENSS names were not changed other than in being moved
to the "t3.ans.net" domain. The following excerpt of a traceroute
from ANS Elmsford to Merit in Ann Arbor illustrates the ANSnet DNS
conventions.

OSI Support on T3 Backbone
==========================
In early December, OSI CLNP forwarding over the T3 backbone was
configured via encapsulation of CLNP over IP packets using the EON
method (RFC1070) until native CLNP switching services are available
on the T3 routers.
One RT from the T1 NSS node at each midlevel/peer site is being
used for the EON encapsulation function. It is our intention to
keep this RT and one other for statistics collection purposes
running at each site.
CA*Net Reconfiguration Status
=============================
CA*Net is working with Merit and ANS to complete their plan to
change their connections to the US (at Seattle, Ithaca and
Princeton) so that the US nodes will run the CA*Net RT kernel and
Cooper [Page 20]
Internet Monthly Report December 1992
become logically part of the Canadian routing domain. This project
has not yet been completed, and so currently the three NSS nodes
from the T1 Backbone (but without the T1 circuits) are being used
to route traffic between CA*Net and NSFNET. Once the software
installation is complete the circuits will be moved over to these
RTs and the full NSS noes will be disabled.
AIX 3.2 Migration Plan
======================
System testing continued in December for the new AIX 3.2 operating
system for the RS/6000 routers. This software will be installed on
the T3 test network in January for final system testing prior to
deployment in early February.
GATED Routing Software Development
==================================
Work continued on the development of GATED as replacement for
rcp_routed software on the T3 backbone. The same Interior Gateway
Protocol (IGP) used by rcp_routed will be supported initially on
GATED as a transitional measure to simplify the deployment of
GATED. Full IS-IS integrated routing will follow in GATED, along
with BGP4 with CIDR routing capability.

Cisco PROM Upgrade on ANSNET
============================
We are finalizing tests that will allow us to upgrade the software
level on all ANSnet Cisco routers to 9.0(3). This will fix several
bugs that currently exist on the current 8.3.X that is installed
across the network.

NSFNET/INFORMATION SERVICES
---------------------------
The Merit/NSFNET Regional Techs meeting will be held in Boulder,
Colorado, January 21 and 22. The conference will convene at US
WEST's Advanced Technologies Conference Center in the University of
Colorado's Research Park. NCAR and WestNet will also be hosting
sessions and activities. The focus of the seminar is operational
planning over the next 6-8 months: CIDR implementation will be
discussed by Vince Fuller of BARRNET and Dan Long of NEARNET will
give an overview of CIDR address allocation strategies; GIX, NAPS,
and Route Servers will be presented by Elise Gerich of Merit to
increase the understanding of the Internet routing implications of
Network Access Points (NAPS) technology as proposed by NSF. The
current status of the NSFNET network and the transition to the
"Next Generation NSFNET" will also be addressed. Requests for the
detailed agenda and additional information may be sent to nsf-
seminar@merit.edu.
"Making Your Internet Connection Count: Technology, Tools &
Resources" will be held in San Francisco, CA, March 15-16. Hosted
by BARRNET, the Merit Networking Seminar is a comprehensive forum
intended for beginning and intermediate network users focusing on
issues of interest to educators, librarians, campus computing
leaders, information systems and networking administrators, and
educational liaisons. Nationally known experts will discuss
network resources, getting connected, and how the network is
effectively being used today by universities, research
organizations, libraries, and public schools. An overview of the
Internet, its tools and resources, and the national policies that
affect its growth will also be presented.
A three-hour hands-on tutorial will be held in conjunction with the
seminar at Stanford University, Palo Alto, CA. Merit staff will
introduce participants to telnet, file transfer, and the latest in
user friendly interfaces: Gopher, archie, and WAIS.

Internet Monthly Report December 1992
activities were reviewed, acknowledging the increasing awareness
and role of user services in the Internet world. The CAUSE 92
Preconference, sponsored by the Coalition for Networked Information
(CNI) was held December 1 in Dallas, Texas. With emphasis on
"Navigating and Navigators: Research and Development in
Navigational Tools and Services for the Internet," Laura Kelleher
of Merit/NSFNET Information Services, presented a study on what is
being used on the Internet as well as participating in several
discussions of Internet tools and resources. Kelleher also
"cruised" the Internet with the members of the Southeastern
Michigan Library Association at Oakland University, MI.

PITTSBURGH SUPERCOMPUTING CENTER
--------------------------------
Since our last report, the Pittsburgh Supercomputing Center
accepted delivery of the CRAY Y-MP C90, the newest and most
powerful supercomputing system produced by Cray Research, Inc., the
Minnesota-based firm that has supplied most of the supercomputing
systems in use around the world. The PSC is the first non-
government site in the U.S. to receive the new system. The C90
features 16 connected processing units, each of which is capable of
performing a billion calculations a second, so that peak speed is
16 billion calculations a second -- six times faster than Cray's
current top-of-the-line system, the Y-MP/8, which the C90 will
replace. It comes configured with 256 million words, (2 billion
bytes) of memory, eight times that of the Y-MP/8, and will be
upgraded to 512 million words sometime this year.
Under the proposal for the National Machineroom Metacenter, the
National Science Foundation Centers are specializing within the
general class of massively parallel processors in order to provide
both large machines and good vendor coverage for use by the
community. We at the PSC are planning our major activity with the
CRAY MPP: T3D, while NCSA will make a major thrust with the
Thinking Machine Corporation's CM-5. TMC found a need for the CM-5
that we have had for the past year; and because of this, we have
taken it out of service. To that end, we have already begun to work
on applications using the T3D Emulator Software.
In November, Matt Mathis and Gene Hastings of our communications
group attended the IETF meetings in Washington, DC. Matt chairs
the BGP Deployment working group and Gene chairs the Network Status
Reports and Network Joint Management groups.

SDSC Network Activities
=======================
During the month we made two major changes to our LAN. The DMZ
Ethernet was changed from a subnet of our Class B address (132.249)
to its own Class C address (198.17.47.) At the same time, the
Center's FDDI ring was split in two. This gives us an FDDI DMZ.
Its Class C address is 198.17.46.
