ANSNET/NSFNET BACKBONE ENGINEERING
----------------------------------
Network Status Summary
======================
ANSnet stability improved in August over the July measurements.
New routing software was deployed in the ANSnet to reduce
instability, and simplify the reconfiguration process.
August Backbone Traffic and Routing Statistics
==============================================
The total inbound packet count for the network (measured using SNMP
interface counters) was 31,945,944,041 on T3 ENSS interfaces, down
2.87% from July. The total packet count into the network including
all ENSS serial interfaces was 37,652,126,636 up 1.02% from July.
As of August 31, the number of networks configured in the Merit
Policy Routing Database was 15249 for the T3 backbone. Of these,
3334 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 10,879.
Rcp_routed Routing Software Changes
===================================
In mid August, the "Dynamic Reconfig" version of the rcp_routed
routing daemon was replaced with the "Better IBGP Aggregation"
version. Problems with the dynamic reconfiguration feature are now
corrected and the effects of configuration runs has been minimized.
The "Better IBGP Aggregation" also has performance improvements
that should improve stability outside of the configuration window.
Release notes provide further details. They can be found in:
ftp.ans.net:/pub/info/t3-rcp_routed/Release-Notes
Rcp_routed has now evolved to a very stable version quite capable
of handling the high load of routing updates. Handling of
intermittent circuits was to be the next target for improvement,
but rcp_routed will most likely be replaced by Gated within a
month. Rcp_routed will be retiring shortly. Further development
will be targeted at gated.
Cooper [Page 8]
Internet Monthly Report August 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). This is intended as a measure of stability rather than
complete connectivity. Stability during August was 97.5% including
disruptions during the configuration windows. Excluding the
configuration windows, stability was 97.9%. This is a slight
improvement over July.
MONTH overall excluding configs
------ ------- -----------------
January 99.1% 99.5%
February 99.0% 99.5%
March 97.5% 99.1%
April 96.1% 97.2%
May 97.4% 98.0%
June 95.5% 96.6%
July 97.3% 97.7%
August 97.5% 97.9%
July stability was improved over June. August was a further
improvement over July. This was despite severe circuit problems at
ENSS136 (College Park) on August 19, 20, 22, and 24.
The access T3 circuit from CNSS58 to ENSS136 was changed. The
local carrier portion of the T3 circuit was highly unreliable for
over a week. Congestion on the T1 backup circuit was quite severe,
and SURAnet had to disable it's FDDI peers at ENSS136 at times to
force backup through the T3 ENSS138 at Georgia Tech. ENSS136 saw
about 6:33 hours of instability (99.1% stable).
ENSS230 (Digital Express) continued to have circuit problems and/or
[CSU problems in early August. A zeros density problem seems to
have been the cause. ENSS230 saw 4-3/4 hours of instability (99.5%
stable). ENSS222 had circuit trouble. ENSS145 (Fix-E) had
problems involving CPU loading due to EGP processing. ENSS135 (San
Diego) had problems due to local power, and UPS power problems in
the adjacent MCI POP (CNSS16, CNSS17, CNSS19). Each of these
ENSS's had 2-1/2 to 3 hours of instability, though for ENSS135 much
of it was during the configuration window (only 47 minutes outside
the window). CNSS16, CNSS17, and CNSS19 saw approximately 2 hours
of instability, approximately 1 hour each during the configuration
window.
The number of nodes experiencing a great deal of outage improved
over June and July, though ENSS136 shows up in the >5hr column.
Cooper [Page 9]
Internet Monthly Report August 1993
The breakdown by sites is as follows (these figures include
instability seen during configuration runs):
MONTH >5 hr >2 hr > 1hr >30 min >15 min <= 15min
------------------------------------------------------------
January 0 0 1 8 19 55
February 0 0 1 24 19 41
March 0 4 18 23 23 22
April 2 2 3 13 12 57
May 0 4 33 32 15 5
June 3 21 35 18 12 3
Jul 0 12 28 44 6 1
Aug 1 5 28 21 17 15
During August, MCI corrected the problems with the St. Louis to
Denver link and other links in the area which previously suffered
outages associated with flooding in the midwest. This accounts for
much of the shift toward improved stability. Only half as many
nodes saw over 2 hours of instability and far more saw under 15
minutes and 30 minutes.
Route Table Growth
==================
The number of networks actually announced to ANSNET grew by about
7.5% in August. There were 15,249 configured networks by the end
of August. The maximum number of routes observed was 10,879.
MONTH MAX Growth RATE(%)
===== ==== =============
01/93 6654 6.65
02/93 7037 5.76
03/93 7767 10.37
04/93 8239 6.08
05/93 8961 8.76
06/93 9534 6.39
07/93 10113 6.07
08/93 10879 7.57
On average for routes that were announced, the primary route was in
use 98.8% of the time, secondary was used 1.6% of the time and a
tertiary or less preferred route was used less than 0.6% of the
time (due to rounding this adds to 101%).
There were 3,334 networks configured by August 1 or earlier but
were never announced during the the entire month (silent nets).
Eight peer networks had over 100 each, accounting for 2,266 of
Cooper [Page 10]
Internet Monthly Report August 1993
these. There were 4,105 networks configured by August 20 but never
announced by the last week of August.
Notable Outages in August '93
=============================
E129 (Champaign) suffered an extended outage on 08/12 due to power
problems.
E157 (Louisville) suffered extended outages on 08/24 and 08/25 due
to circuit problems.
E222 (InterNIC) suffered extended outages on 08/02 and 08/14 due to
circuit problems and on 08/30 due to power problems.
E230 (DigEx) suffered an extended outage on 08/31 due to power
problems.
E136 (College Park) lost T3 connectivity on 08/23 and 08/24 due to
circuit problems.
UNAM (Mexico) suffered an extended outage on 08/06 due to site
problems.
Xlink (Germany) suffered an extended outage on 08/18 due to power
maintenance.

Real-Time Multicast Communications and Applications
During August, testing was completed in the DARTNet on shared
stream service. At this point, implementation and basic testing
has been done for the 4 realtime multicast communications services
-- anycasting, multi-level flows, Resource Coordination Objects
(RCOs), and shared streams -- and we have begun integrating them
with distributed real-time applications.
We began working on the nv video program to add multi-level
multicast flow support to it. This involves using a high frame
sampling rate, and tagging the outgoing packets with different
priority levels. E.g., half of the frames are marked with the
lowest priority value, 1/4 of the frames with the next-higher
value, etc. A receiving nv application can then pick a frame rate
based on processing capability and available bandwidth, and request
Cooper [Page 11]
Internet Monthly Report August 1993
all frames at and above a cut-off level. With proper pruning and
multi-level flow support in mrouted and DVMRP, this will allow
optimal forwarding of multicast packets, with packets from unwanted
subflows being dropped along routes containing only low-rate
receivers.
The RCO paper that we mentioned last month has turned into two
papers, one on the general concepts and design of the RCO system,
and one describing the prototype protocol and implementation
details. These should be available for distribution soon.
(See January '93 and March '93 Internet Monthly Reports for more
details about the application and communications services being
developed.)

CONCERT
-------
The communications research group at MCNC has taken delivery of a
Cray Y-MP EL. This entry level system will be used as a development
system to support the gigabit networking research undertaken by the
group. Activities expected to involve the Cray Y-MP EL include:
porting and evaluation of new transport layer protocols to UNICOS
including optimized versions of XTP, PIP and PIPE; development of a
prototype HIPPI to ATM gateway with cryptographic capabilities;
development of direct bus attached ATM interfaces for the Cray Y-
MP; and development of collaborative environments involving
scientific computing.
The communications research group has been experimenting with
network resource management and packet video. The group's IP/ATM
network testbed has been expanded to four Sparc10s dually connected
through an Ethernet and a Fore System ASX-100 ATM switch. The group
has four prototype video capture boards from Sun and three Parallax
XVideo cards (with JPEG compression) installed in the workstations.
Experiments with network resource management and packet video
continues in this environment.
A software H.261 codec implementation has been completed. It has
been tested using XVideo as a frame grabber. It runs at 1.15 frames
per second between two Sparc10 with CIF size and 4.5 frames per
second with QCIF size. The codec is used in studying codec-network
interface issues. A two-level coding option is also being
implemented.

DIRECTORY AND DATABASE SERVICES
Directory and Database Services had a workstation in the InterNIC
booth at InterOp, and we demonstrated our services to booth
visitors. Demonstrations centered on the Directory of Directories
(accessed through WAIS and Gopher) and on our Directory Services.
Our Directory Services currently use X.500, Netfind, or WHOIS to
help locate individuals on the NSFNET. Our X.500 DSA is tied in to
the PSI White Pages Project and is linked to X.500 servers
worldwide. More than one million entries are accessible through
this system. The WHOIS server on ds.internic.net checks the
Registration Services WHOIS, the DISA NIC WHOIS, and our local list
of individuals who are not network points of contact. Netfind,
written by Mike Schwartz at the University of Colorado, uses a seed
database, DNS, and finger to find users in the Internet. X.500,
WHOIS, and Netfind are accessible through Gopher, and X.500 and
Netfind are accessible via Telnet on our server (log in as x500 or
netfind, respectively, on ds.internic.net; no password is
required).
A reminder - if you would like to help the Internet community find
a resource that you offer, send mail to admin@ds.internic.net and
we will send information about listing your resource in the
Directory of Directories.

GIGABIT NETWORKING
Atomic
------
Work on the ATOMIC LAN is proceeding on several fronts.
Kernel-AC Software Work
In the current version of the ATOMIC LAN, address resolution is
performed by a program called the Address Consultant (AC), which
utilizes a special address family (AF_ATOM) to send link level
probe packets when it maps the network. This month we began the
task of moving the AC from user space into the Sun kernel, where it
will perform functions analogous to the Ethernet Address Resolution
Protocol (ARP). The mapping function that the AC performs is much
more complicated than ARP. It is expected that the kernel-based
Cooper [Page 16]
Internet Monthly Report August 1993
implementation of the AC will simplify the process of porting the
Atomic software to other platforms, since it will eliminate the
need for the AF_ATOM address family.
Design of 486-based VL-Bus ATOMIC Interface
We have been continuing our high-level design for a 700Mb/s
interface for a 486 VL-bus system. We expect a nearly complete
specification by the end of August. The interface will have DMA
access by the host system and separate sending and receiving Mosaic
processors.
Cable Component Testing
We have also been continuing work testing the various components of
a high-speed cable for the ATOMIC LAN. Our goal is to create a
bidirectional 500Mb/s cable over a 100' length of twisted pair
(25pr) cable. Specifically we have been testing the differential
driver chips (ATT 41mm), the Slack-20 v4.0 chips created by Caltech
and various grades/lengths of twisted pair cable. Our expectation
is to build a low-cost cable for installation over relatively short
distances at ISI. The Slack chip will eventually be replaced by
the "Dialog" chip that is also designed by Caltech. The Dialog
includes flow control and fault tolerance. We are participating in
Dialog design discussions with Caltech.
Simulation of the ATOMIC LAN
We created a simulator for the ATOMIC LAN that allows us to
evaluate the performance of the 16x16 crossbar switches in our
network and to examine the impact of various high-level routing
algorithms in a complex network. The simulator allows us to examine
much larger topologies than we can currently build in the lab and
can be used as a tool to aid the installation of a production LAN.
The simulation results have led us to re-think the routing strategy
used in the Address Consultant.

MULTIMEDIA CONFERENCING
On August 17, an MBONE teleconference meeting of the IETF AVT
working group was held to review the changes in the "next-to-last
call" draft specification for the Realtime Transport Protocol and
reach agreement on several questions. One item agreed was to seek
"proposed standard" rather than "experimental" status when the
draft is submitted to become an RFC. This should happen in
September, after the "last call" edition of the draft spec is
completed to incorporate the changes discussed in the meeting and
some additional explanatory sections on usage scenarios.
Our teleconference session orchestration program, mmcc, was
demonstrated at INET'93 with audio/video calls placed to remote
locations such as ISI, where the camera gave a nice view of the
marina. To avoid requiring an individual to answer the calls, an
option was added to the call setup process in mmcc to allow an
automatic yes or no answer when contacted, rather than ringing.
Cooper [Page 19]
Internet Monthly Report August 1993
For automatic calls, mmcc can also send a Tcl command to instruct
PARC's nv program automatically to begin sending video at session
startup. This is an example of the kind of cross-application
communication that will be necessary to fully integrate the tools
in a teleconferencing suite. We are converting mmcc to Tk/Tcl to
facilitate experimentation in this area, and plan to publicly
release that version of mmcc.
One function which will require coordination among the tools is the
selection of the quality of service. Mmcc has been augmented to
provide a range of QoS choices to the user in abstract terms and to
share the initiator's QoS choice with all potential participants.
It then maps the abstract request to a flow specification and
requests resource reservations for both senders and receivers via
the RSVP API. To aid in testing RSVP, direct control is also
provided to change the selected flow spec. Two open questions are:
how should the high-level QoS abstraction be mapped into a flow
specification, and which components of the end-system suite should
perform the mapping and make the reservations.
At the workshop on Programming Abstractions for Distributed
Multimedplications held in conjunction with Multimedia '93, Steve
Casner gave a keynote presentation on "Multimedia Abstractions and
the Internet" and Eve Schooler gave a presentation as part of a
panel on "Session Abstractions for Coordination and Control".
Steve Casner made a presentation on "Session Management for
Internet Teleconferencing" at the ARPA Networking PI meeting in
Santa Rosa.

Beta testing of the Livingston PortMaster network access server by
selected UM/MichNet personnel at the University of Michigan
Cooper [Page 22]
Internet Monthly Report August 1993
continues. The purpose of this period for beta test is to evaluate
the services and performance provided by the PortMaster before
making it available to the greater community. The PortMaster is
expected to provide a superior level of dial-in service, as well as
PPP and SLIP access.
The dial-in service offered via the UM/MichNet NAS has been
configured to be as flexible as possible, at a variety of modem
speeds and with or without error correction and data compression.
The UofM machine will be used for PPP access only, with public
availability to authenticated users upon completion of successful
testing.
Common connection establishment procedures have been determined to
be the principle requirements which must be met by a NAS
participating in the MichNet pool of ports, as well as the ability
to interface with an authentication helper interfacing with
serveral authentication servers. Michigan State University is
working with Xylogics, where the Xylogics Annex terminal service
has been deployed. State-of-the-art network access will be
provided to users around the state with the deployment of Network
Access Servers throughout the MichNet backbone.
The College of Education at Westerm Michigan University is
coordinating a project to offer west Michigan school districts
access to WMU computing resources and the Internet during the
1993-94 school year. Several districts have expressed an interest
in this initiative which will support accounts for teachers and
their students. Saginaw Valley State University sponsored a
three-week Summer Research Institute which included use of SVSU's
Internet connectivity. Participating in the Institute, was a team
of four students and two teachers from Bay City Central, a local
high school, which won an environmental research competition,
"EarthVision," sponsored by the Environmental Protection Agency.
The Greater Flint Educational Consortium announced its funding of a
Modem Pool & Information Server project in Genesee County. A group
of modems will be installed for public access via computers, and
the Information Server will act as a computerized bulletin board
for the educational community. Ultimately, students, parents and
teachers in the area will be able to access computerized events
calendars, homework listings, library holdings and local college
admissions requirements.
Hope College, a MichNet affiliate, upgraded its connectivity to the
MichNet regional backbone as a 1.5Mbps (T1) link using a cisco
router. The new link runs from Hope to the MichNet backbone router
in Grand Rapids. Two new MichNet public dial-in access sites,
Holland and Big Rapids, are available. The cooperative efforts of

RIPE
-----
Introduction to the RIPE NCC
----------------------------
The RIPE NCC
RIPE (Reseaux IP Europeens) is a collaborative organisation open to
all European Internet service providers. The objective of RIPE is
to ensure the necessary administrative and technical coordination
to allow the operation of a pan-European IP network. Much of this
work is achieved through voluntary effort. RIPE does not operate a
network of its own.
The RIPE Network Coordination Centre (RIPE NCC) is a European
organisation with a charter to support RIPE. It is specifically
focused on undertaking those activities which cannot be effectively
performed by volunteers from the participating organisations. As
such, it provides a wide range of technical and administrative
support to network operators in the Internet community across
Europe. The RIPE NCC currently has 3 permanent staff members. The
RARE association provides the legal and financial framework for the
NCC.
RIPE NCC Activities
Regional Internet Registry
In order to operate IP networks in the Internet or between
organisations each physical network must use a unique IP address.
Other number spaces like the Autonomous System numbers need also be
maintained in a way to guarantee uniqueness. This is the task of
the Internet Registry. Before the RIPE NCC existed these tasks
were performed centrally for the whole Internet under the auspices
of the US Department of Defense and funded by various US agencies.
Recently it has been recognised that the fair and hierarchical
allocation of IP address space is a necessity for the Internet to
survive.
Cooper [Page 27]
Internet Monthly Report August 1993
To answer this need the RIPE NCC has set up the Regional Internet
Registry and a network of Local Internet Registries at IP service
providers for Europe.
The RIPE NCC has identified and helped to set up more than 60 local
registries to date. These local registries serve either the
customers of a particular service provider or all organisations
within a country which do not have a service provider. The latter
category of registries is called "Non-Service Provider" registry, a
community service which to date is being provided free of charge.
So far 22 organisations willing to provide this have established a
non-service provider registry.
Most European organisations now have access to a local registry
which knows the local environment, speaks the local language and
can provide most registration functions locally. Only requests for
large amounts of address space are being reviewed by the NCC. As a
result, IP number allocation to European organisations is now
easier, more timely and last but not least fairer than before.
Particularly the local support and the increased responsiveness are
appreciated by network operators.
To date the European Internet Registry system has allocated more
than 14,000 network numbers, 800-900 of which are currently being
routed on the Internet. This shows that many organisations are
using the Internet protocols without actually connecting to the
Internet, at least not initially. Another clearly visible trend is
that the vast majority of new address space is assigned for
purposes other than research and development.
The RIPE Database
In many operational situations ranging from loss of connectivity to
intrusion attempts it is necessary to establish quickly who is
actually responsible --a specific IP network or DNS domain-- and
find a way to contact them.
To answer this need one of the core activities of the NCC is
maintaining the RIPE Network Management Database often referred to
just as "RIPE Database". This database contains information needed
for the technical coordination of European IP networks. The RIPE
database is maintained at the RIPE NCC in cooperation with local
Internet Registries throughout Europe. It can be queried from
anywhere on the Internet using a variety of methods including the
standard WHOIS service. Currently decentralised servers for access
to the database are being set up.
Cooper [Page 28]
Internet Monthly Report August 1993
General Coordination
Network operators need to coordinate with each other in order to
maintain the functionality of the European Internet. RIPE is the
forum for this coordination and much of it is done at the meetings
RIPE holds three times a year. RIPE working groups discuss
specific problems and produce recommendations. Between RIPE
meetings a focus for these activities is needed.
The NCC supports general RIPE activities by providing a focal point
for and by fielding many queries. This activity is not easy to
describe or quantify. Nevertheless the NCC plays an important role
in many RIPE activities just by providing a permanently staffed
location that keeps track of activities and is able to perform
small but urgently needed tasks. In addition the NCC organises the
RIPE meetings.
Information Services
The RIPE NCC maintains the "RIPE document store" which is a
collection of RIPE`s own documents and information relevant to the
Internet community in general such as RFC's, FYI's, information on
the IETF, IEPG and other technical documentation.
Publicly available software tools which are useful for network
operators are also made available via the document store. The
document store can be accessed with traditional tools such as
interactive login from the Internet and via X.25 based networks and
FTP. It can also be accessed with many of the new resource
discovery tools such as Archie, Wide Area Information Server
(WAIS), Gopher and World Wide Web (WWW).

UCL
----
We have now integrated LBL's Class Based Queueing code into a
streams module that is plumbed between the IP output module and and
System V compliant DLPI type link level device driver. Access to
the module to program flow classes is implemented via an ioctl at
the moement that adds or subtracts fixed bitmap patterns that are
used in mask and matches on packets to flows.
A more complex piece of code to provide efficient matching on less
obvious (less friendly) keys in packets that identify flows is
being developed alongside this approach.
Testing across the fatpipe is taking place in september, with the
seperation of MICE and ARPA Project multimedia and other traffic
from UCL service traffic, and several (albeit artificial)
subclasses of traffic.
Traces of the traffic will be taken to try to demonstrate the
effectiveness of the scheme. Essentially, deliberate overload
conditions will be set up, and conditions where multimedia traffic
threatens the service, and vice versa, and the queueing controls
turned on and off periodically.
During August, Kirstein attended Inet 93 and t meet with many
collaborators stateside.
