INTERNET MONTHLY REPORTS
------------------------
The purpose of these reports is to communicate to the Internet Research
Group the accomplishments, milestones reached, or problems discovered by
the participating organizations.
This report is for research use only, and is not for public
distribution.
Each organization is expected to submit a 1/2 page report on the first
business day of the month describing the previous month's activities.
These reports should be submitted via network mail to Ann Westine
(Westine@ISI.EDU) or Karen Roubicek (Roubicek@NNSC.NSF.NET).

WIDEBAND NETWORK
The Wideband Net and associated Arpanet IST lines suffered a
degradation in service during the past month as frequent resets
plagued the network. Work is in progress to correct this problem.
Software to support IP multicasting over the Wideband Net was
distributed in August. The software extends the HAP group
addressing scheme to allow extra-HAP (32 bit) destination addresses
to be specified in messages sent to the Wideband Net. Network
hosts may join such an address and will receive copies of all
messages sent to the address.

Internet Monthly Report August 1988
SATNET
The operation of the SATNET was very stable during August. There
were no unscheduled outages.
The antenna at the Tanum Earth Station was repointed to a different
satellite on August 17th, thus removing it from the SATNET.
Jon Crowcroft (University College London), Claudio Topolcic (BBN),
and Karen Seo (BBN) attended the ACM SIGCOMM 88 Symposium held at
Stanford University, Stanford, California. Karen presented a
paper, "Distributed Testing and Measurement across the Atlantic
Packet Satellite Network (SATNET)", which summarized the results of
the SATNET Measurement Taskforce. The taskforce plans to write
several additional reports that will contain more detailed
descriptions of this work.
INTERNET R&D
We shipped hardware and software to RSRE and NTA to support the
installation of a line between the gateways at NTA and RSRE. This
will get NTA back on the air after their Satnet earth station was
pointed at the wrong satellite.

Internet Concepts Project
Work on a network simulator sufficient to test some congestion
control ideas has been pretty much completed. It is intended for
testing several differing approaches for IP congestion control that
depend upon the host IP module maintaining separate congestion
control queues indexed by destination network. For that purpose it
is assumed that gateways generate Source Quench messages when their
queues overflow. That information, when it returns to the source
host, is used to clock out IP packets to the affected destination
network much the way cars are clocked onto freeways when a freeway
is congested. The simulator will allow testing these approaches
under differing topologies, loads and with differing link
characteristics.

Los Nettos
A user-supported regional network has been formed in the Los
Angeles area to provide connectivity between sites such as
individual campuses and research centers in the area and to provide
connectivity to long haul networks for all the campuses and
centers.
This regional network is called "Los Nettos". Los Nettos will
connect to several long haul and national networks, such as the
ARPANET, the NSFNET, the WBNET, and the DRI. Los Nettos is
operated by the member organizations, not by DARPA, or NSF, or DOE,
etc.
Westine [Page 3]
Internet Monthly Report August 1988
Los Nettos is being developed in phases. Each phase will add a
group of sites together. This phased approach allows a reasonable
topology for Los Nettos to evolve. The technical committee assists
in the development of the system design and the topology. One
important feature of Los Nettos is that it is "high speed", all
connections and links are (and will be) at least T1 (1.5 mb/s)
rate.
Five organizations have already joined Los Nettos and the first
phase of implementation is under way. The sites in phase 1 are:

Multimedia Conferencing Project
The voice echo canceller implemented for the packet voice system is
now operational and ready for testing over the Wideband Net. It is
implemented on an NEC 77P20 digital signal processing chip and is
mounted on a Switched Telephone Network Interface (STNI) card. The
STNI, developed by ISI and BBN, sends and receives TouchTones and
digitizes voice signals to interface between a telephone line and
the packet voice terminal program. Echo occurs when the far-end
signal is reflected from the 2-to-4 wire hybrid circuit required in
each STNI to couple voice signals from the packet system into the
two-wire telephone network. The echo canceller uses the well known
transverse filter technique to estimate the echo and subtracts this
estimate from the near-end signal. We have fine-tuned the echo
canceller algorithm parameters for the local ISI environment and
will proceed with testing over the satellite.
Improvements were made in the software implementations of MMCC (for
conference control) and PVP (the video packet host in the
Butterfly). The I/O interfaces in PVP, which communicate with the
video codec and the Voice Funnel gateway, were modified to use a
newer version of BBN's synchronous I/O library. This is in
Westine [Page 4]
Internet Monthly Report August 1988
preparation for interfacing with BBN's upcoming Butterfly ST
Gateway.
A first draft of a document describing the multimedia conferencing
system was composed this month. Its purpose is to give an overview
of the system and to define the requirements for installation of a
new MMC site. It outlines the major components of the
teleconferencing system, provides some cost estimates, and states
current impressions as well as future directions. This document
was prepared in Diamond and includes several pretty diagrams.
After review it will be available for distribution.

Annette DeSchon continued work on the BFTP programs, adding some
new features and making some minor repairs. The BFTP programs
include an internet server, a TTY-style interface for BSD machines,
and a "bftptool", which runs on a Sun workstation. Sources will be
available via anonymous FTP in the next few days. A BFTP server is
currently running on "hobgoblin.isi.edu", port 152, and can be
accessed via the "telnet" protocol.

1. Jeff Simpson continues to work on policy issues in network
routing. This past month he toiled with the OPSNET network
simulator and now has it running on a Sun workstation. He will
be using the simulator as a testbed for policy routing
strategies. Additionaly, he is collecting and organizing
information on network policy in order to write a summary of
policy systems now popular in the Internet.
2. Paul Schragger is reviewing the literature on catastrophe
theory and its application to network performance and behavior
analysis. The goal of this work is to evolve control schemes
that globally optimizes network utlization in the face of
congestion and misengineered implementations. Also, Paul
continues to work on the MIT network simlator, in particular
to construct a Poisson packet source. Both the delay between
packets and the packets lengths can be fixed or exponentially
distributed. He is using this to explore the standard queing
Westine [Page 6]
Internet Monthly Report August 1988
models and their behavior compared to a simple catastrophe
model.
3. All of the original six NSFNET Backbone fuzzballs are back on
the air, two (NCAR and UIUC) configured as primary time
servers and the remaining four as secondary time servers.
Precision Standard Time, Inc., kindly furnished a Model 1020
WWV-synchronized clock for evaluation. A driver for it
instantly materialized and it is now ticking happily on one of
our U Delaware fuzzballs. Also, the fuzzball timekeeping code
was extensively revised to improve its resistance to
falseticking radios, some of which are becoming increasingly
cranky as Solar Cycle 22 ramps up to the max.
4. Continued low-level problems with U Delaware access to the
Internet via SURANET have not been resolved. The problems
result in occasional loss of packets, sometimes accompanied by
ICMP error messages, under conditions of very low traffic and
general tranquillity. The problems are readily noticeable in
the logs for the various time servers, both here and elsewhere
in the internet, and are almost certainly not new. As SURANET
is now claiming reachability of about 200 networks, we suspect
its switching fabric might be RIPping in some places.
5. Dave Mills presented a paper and chaired a session at the
SIGCOMM 88 Symposium IAB meeting in Palo Alto, presented a
briefing on the Dissimilar Gateway Protocol at DCEC in Reston
and attended a NAS meeting on Telecommunications Network
Survivability in Washington. Work continues with Paul
Schragger on developing a strawman proposal for a high-speed
reservation-switched network model suitable for early
evaluation. One of the weekend projects was a close
examination of ancient and modern calender systems and their
synchronization principles for the lunar, solar and ritual
year. Well, this rather got out of hand and may result in a
new timestamp format for Maya Long-Count dating of Internet
events.

NSFNET BACKBONE (MERIT)
August was the second month of production mode for the NSFNET
backbone. Activity on the NSFNET backbone is running
smoothly. Facilities for the formal collection of data are
beginning to be implemented.
New campus nets are still being added. As of August 31, 241
NSFNET known campus nets were in our routing tables and 247
ARPAnet networks were also reachable through the NSFNET
backbone. Thus, over one half of the networks in the Internet
are directly reachable via the NSFNET backbone.
IBM and the Merit/NSFNET Internet Engineering group are
experimenting with slow-scan motion packet video. Video images
are now being transmitted between IBM's research facility in
Yorktown and Ann Arbor. A demonstration has been given to
Steve Wolff at the NSF through the NSFNET backbone.
In its present state, packet video would use a significant
amount of bandwidth. Currently, video packets are not
compressed. The future promises a number of changes and
enhancements. Full-duplex is a logical step to explore, so
that video images can be sent and received at the same time.
Development of multi-cast images would allow more than one
location at a time to receive the same video image.
The NOC is now operating on a twenty-four hour schedule. To
combat "air traffic controller syndrome" an innovative,
flexible scheduling system is being implemented.

International connectivity has become an important project
this fall. The Ontario regional network will be connecting
into NSFNet via Cornell early this fall. A connection to
CNUSC (Centre National Universitaire Sud de Calcul) in
Montpellier, France should be implemented by mid-fall. The
issue of user support in a national, multi-networked

UNIVERSITY OF ILLINOIS AT URBANA-CHAMPAIGN/NCSANET
A problem with our Arpanet gateway machine (uxc.cso.uiuc.edu)
that involved running out of network mbufs after two to four
days of operation was resolved. The solution was to replace
the 3Com Ethernet board with a second Interlan 1010A card.
Our WWVB clock (truechimer.cso.uiuc.edu) is still ticking in
tune with NBS despite the steel framework of the building
addition going up around the antenna.
A second Class B address was approved by Hostmaster (uiuc-ncsa

JVNCNET
This report is designed to inform the JVNC Consortium and
JVNCnet network members as well as the Internet community of
monthly status of the JVNCnet network. The data used on this
report is collected using a number of techniques developed at
JVNC.
Monthly Status Overview:
The overall uptime for the gateways this month was 84.85%
(worst case, this number considers that all gateways are
unreachable when JVNCA is down). The measured uptime when
JVNCA was available (94.70% of the time) was for an average on
all the gateways 80.35% available.
The "estimated" amount of traffic in and out of the JVNCNet
system for this month was 340,000,000 packets. This is a very
high number (specially considering that 15 of the 25 gateways
are VAXs, and their performance was highly degraded). Of this
traffic, approximately 30% was coming from the NSFNet, 10%
from the ARPANET, and 60% from JVNCNet sites.
The NSFNet network (as seen from JVNC) is performing very
well. Interactions between the MERIT staff and the JVNC staff
is a demonstration of the high degree of cooperation that
exists between the two organizations. The result is a smooth
operation, which we expect will develop even further.
Westine [Page 10]
Internet Monthly Report August 1988
Plans are moving ahead for the connection of the JANET (Joint
Academic Network) in the UK to the NSFNet at JVNC and the
connection of the NORDUnet (Nordic Countries Network) to the
NSFNet at JVNC. Both connections will be on 56kbps circuits
(over satellite), the connection to JANET will be X.25
protocols, while the connection to NORDUnet will be a TCP/IP
connection. In either case, CISCO routers will be utilized.
Both routers will be connected to the JVNC External network
(ethernet) joining the NSS, and two JVNC (core) CISCO routers
(which are both connected to PSN16).
The JVNC Network Operations Center (JVNCNet NOC) provides
support to the JVNCNet network as well as the internal network
of the JVNC. The NOC is staffed by the network staff from 9
a.m. to 5 p.m. Mon-Fri, and is on call between 5 p.m. and 9
a.m. and during weekends and holidays. The computer operators
monitor and perform minor troubleshooting tasks between 5 p.m.
and 9 a.m. and provide for backup network operations center.

The network has been getting much more reliable as we correct
residual problems left from the complete reorganization over the
summer. There were only 4 transient and no sustained outages in
external connectivity during August which were caused by PSC
resources.
The SURAnet T1 link is now isolated by a new gated agent, psc-
gw2.psc.edu. PSC and SURA are providing full secondary NSFnet
access for each other through this link.
PSC is also providing secondary NSF access for PREPnet sites who
are using JVNC as their primary. The affected networks are Penn
State, Univ of Penn, Drexel, Temple and Lehigh.
The DEC VMS 8810 front ends to the Cray are now running SRI
Multinet TCP/IP. This has solved many problems with network access
to the Cray, but there is still an intermittent serious problem
with the DEC DELUAs. This affects DECNET and all of the TCP/IP
implementations we have tested. Our next step is to upgrade VMS to
version 4.7.
There have been other internal problems only affecting access to
the Cray, including a flaky ethernet interface in a Proteon P4200
and a power interruption to the Cray machine room.

SESQUINET
The complete initially proposed SesquiNet configuration has been
operational for a year now. The following campus networks are
being served, and are advertised via EGP to NSFnet and (currently
via UIUC) to the Arpanet core:
Baylor College of Medicine 128.249
BCM-Technologies 192.31.88
Houston Area Research Center 192.31.87
Prairie View A&M University 129.208
Rice University 128.42
Texas A&M University 128.194
Texas Southern University 192.31.101
and the University of Houston 129.7
The new NSFnet backbone node at Rice University became operational
during the last week of June, and has proved quite reliable. FTPs
of 96kb/s across the new NSFnet are typical.
In cooperation with the University of Texas, we are building a
triangular network including UT-Austin and the Sesquinet sites at
Rice and Texas A&M. This triangle will connect Sesquinet (and
NSFnet) to THEnet, a multi-campus network centered at the
University of Texas. We hope this will be the first of several
such cooperative projects.

WESTNET
1. The installation of the T-1 digital circuit between NCAR and
the University of Colorado at Boulder has been delayed because
Mountain Bell lost the order. This has turned out to be
helpful because Dowty Information Systems is delaying the
delivery of the CSU's until mid-September.
2. Carol Ward has come on board to work with David C. M. Wood at
the University of Colorado at Boulder to provide technical
support for Westnet. Her first duties will be to establish
NOC services, and to prepare training materials for Westnet
schools.
3. Los Alamos National Laboratory is now connected via the cisco
IP Gateway at New Mexico Technet.
4. The University of Arizona is now using the IBM NSS at the
University of Utah as their primary route to the Internet. The
switchover occurred the week of August 21, 1988.
5. Three new locations are in the process of connecting to the
cisco Gateway at the University of Utah. These include: the
National Optical Astronomy Observatory at the University of
Arizona, the University of Utah, University of Chicago and
University of Michigan research station at Dugway, UT, and
Southern Utah State College, which has just embarked upon an
ambitious three year program to network all of their campus.

AUTONOMOUS NETWORKS
Follow up work to the July teleconference continues. We have
conducted initial interviews with NSF, DOE, and DCA
representatives regarding policy routing requirements. A list
of general questions and sample scenarios was prepared to
guide the interviews. The next step is to try to express these
verbal statements in a standardized, simplified language
without losing important detail.
Draft summaries of policy routing proposals are planned for
next month.
