Internet Monthly Report October 1990
IAB MESSAGE
The IAB met for one day at Interop '90. Among the matters
discussed at this meeting were the following:
A. Network Management Policy and Direction
Action was initiated to draft a replacement for the network
management policy RFC [RFC-1052, "IAB Recommendations for the
Development of Internet Network Management Standards", V. Cerf,
April 1988]. This will probably involve a meeting or workshop
to consider the future course of network management in the
Internet.
B. Acceptable Use
The IAB will attempt to draft guidelines on acceptable use
policies for mailing lists, and will try to cause the
publication of acceptable use policies for existing transit
networks.
C. International Members
The IAB made a commitment to add at least one non-US member, to
be chosen at the January 1991 meeting. This reflects the
increasing internationalization of the Internet.
D. ANSI Affiliation
The IAB discussed possible mechanisms for affiliation with ANSI
for the purposes of setting Internet standards. No conclusion
was reached, but investigation is continuing.
E. RSADSI Agreement
The IAB reviewed the latest draft of an agreement that an
organization will have to sign with RSA Data Security, Inc. in
order to become a certifying authority for Privacy Enhanced Mail
(PEM) certificates. This agreement draft will shortly be
published for information.
F. IP Address Space Growth
Noel Chiappa, IESG area director for Internet Services,
summarized the alternatives for handling future growth in the
number of Internet network numbers. Although the duration of
the present exponential growth is by no means certain, it was
Westine [Page 3]
Internet Monthly Report October 1990
agreed that the responsible approach is to plan for the worst
case.
The emphasis of this discussion was on exhaustion of the IP
address space, although it was recognized that routing
catastrophes are likely to come much sooner.
G. OSI NSAP Address Assignment
Dave Katz provided valuable input to a discussion on the
assignment of NSAP addresses for OSI nodes in the multiprotocol
Internet.
When complete, minutes of this meeting will be announced and made
available for anonymous FTP. The IAB will meet jointly with the
IESG in January 1991. In addition, all those IAB members who are
able will attend the Boulder IETF meeting.
INTERNET STANDARDS ACTIONS
The IAB has approved the following IESG recommendation:
o Proposed Standard state for the MTU Discovery procedure
developed by the "IP MTU Discovery" Working Group of the IETF,
chaired by Jeff Mogul.
This proposal elicited considerable discussion, since it will make
a significant change in the fragmentation strategy of the Internet:
the Don't Fragment bit in the IP header will normally be turned on.
The Working Group had examined a number of alternative
possibilities and made a convincing case that their approach best
meets the scalability requirement while handling backwards
compatibility in a reasonable manner.
The IESG recommended the approval of:
o Proposed Standard state for the Telnet Environment Option,
developed by the IETF "Telnet" Working Group, and described in
the Internet Draft <draft-ietf-telnet-environment-01.txt>.
However, the IAB has not yet approved this, because of concern that
this option could be an open door for non-interoperable,
undocumented, vendor-specific Telnet options. Resolution of this
issue with the IESG and the Telnet WG is underway.

PRIVACY AND SECURITY
--------------------
Steve Kent chaired a panel on Internet Privacy-Enhanced Mail at
Interop '90 early this month, and software and prototype
hardware being developed by BBN in support of the P-E Mail
registration process were shown at BBN's booth during the
exhibition. Panel speakers included David Balenson, Steve Kent,
and Ken Rossen of the PSRG and Burt Kaliski from RSA Data
Security, Inc.
The Privacy and Security RG met for three days from October 23-
25 at MITRE's McLean, Virginia facility, thanks to the
hospitality of Rob Shirey. Major topics of discussion during
this meeting were implementation status of and protocol changes
to P-E Mail. The ongoing beta test of TIS's reference
implementation, certificate interoperability testing with MIT
and DEC implementations, and discussions during the last several
PSRG meetings have all helped solidify a list of changes to the
Westine [Page 5]
Internet Monthly Report October 1990
RFCs. This list will be distributed presently on the "pem-dev"
mailing list. Editing of the RFCs is underway now with an
expectation that revisions will be submitted within the next
couple of months. RFC 1113 is being edited by John Linn, 1114
by Steve Kent and Ken Rossen, and 1115 by David Balenson.
Subsequent to the RFC reissue, major work items will be the
upgrade of TIS's reference implementation for compatibility with
the changed RFCs, integration of BBN's ON software and hardware
with the mail processing implementation, and preparation by
RSADSI for assumption of its role as top-level certification
authority and public notary. In anticipation of the latter
item, representatives from BBN and RSADSI met early this month
to exchange documentation for ON/CA hardware and software and to
discuss further plans for support of RSADSI's role. At the
McLean PSRG meeting, more detailed scheduling work was
initiated, and RSADSI, BBN, and TIS expect to consult further on
scheduling matters during November.
Rob Shirey supplied a draft Internet Security Architecture RFC
for discussion at the McLean meeting. The comprehensive
architecture provides a framework for diverse protocol security
enhancement efforts in the Internet community. The RG went over
this document in some detail during the meeting. Group members
in cooperation with Steve Crocker, IETF AD for Security, will be
considering which other Internet RGs and WGs are best suited to
specific contributions to the architecture.
The draft Internet Security Policy guidelines document supplied
by the Security Policy Working Group was also discussed at the
McLean meeting. Reaction to this document was also generally
favorable, and Steve Crocker will be conveying specific comments
to the draft authors.
Other topics discussed at McLean include plans for the MD4
algorithm in the Internet, and further interactions between the
PSRG and the IETF. The latter included a discussion of the
newly formed Security Area Advisory Group (SAAG). More detail
on these topics appears in Steve Crocker's report.
The next meeting of the PSRG will be held from 12-14 February at
Xerox in Pasadena, CA.

COLLABORATION TECHNOLOGY
------------------------
No report received.
INTERNET ENGINEERING REPORTS
----------------------------
1) Reminder -- The next IETF meeting will be December 3-7, 1990 in
Boulder Colorado. The meeting is being jointly sponsored by by
Westnet and NCAR. Carol Ward (University of Colorado) and Don
Morris (NCAR) are the local hosts.
Logistics information and a preliminary agenda have been sent to
the IETF mailing list. For a copy of this information, or to be
added to the IETF mailing, please send to IETF-REQUEST@ISI.EDU.
2) We have made another minor change in how the IETF areas are
aligned. We have decided to divide the activities of the Host and
User Services Area (Craig Partridge/BBN). The Host and User
Services area has included 3 types of activities: application
services (eg, nfs, rpc, graphics, etc), transport services (eg,
TCP, UDP), and user services. The first will be moved into the
Applications area (Russ Hobby/UCDavis), the second will be moved
into the Internet area (Noel Chiappa/Consultant), and user services
will be made into a separate area by itself.
I am very pleased to announce that Joyce Reynolds/ISI will be able
to join the IESG as area director for the new User Services area.
Joyce was formerly the chair of the User Services WG. Craig will
remain on the IESG in an at-large position.
3) Report on documenting the IESG standards process (from David
Crocker/DEC):
A preliminary draft of the IETF standards process was submitted to
the IESG, as a basis for further discussion. The handling of
materials which come from sources other than IAB working groups is
proving particularly challenging. Further, there appears to be a
need to balance near-term and/or community-desired solutions which
might not represent as strong a technical solution as the IAB and
IESG would want.
Westine [Page 7]
Internet Monthly Report October 1990
4) Report on the Routing Area (from Bob Hinden/BBN)
This is the month to announce name changes for two working groups.
The Interconnectivity working group (IWG) is now the Border
Gateway Protocol working group (BGP).
The Open Routing working group (OR) is now the Inter-Domain
Policy Routing working group (IDPR).
The new names better reflect the work that each group is doing.
A charter was written by George Clapp for the new routing area
working group dealing with IP routing over large public data
networks. The group will meet for the first time at the upcoming
IETF meeting in Boulder, CO, Dec. 3-7. The charter is as follows:
IP over Large Public Data Networks (iplpdn)
Chair(s):
George Clapp, meritec!clapp@bellcore.bellcore.com
Mailing Lists:
General Discussion: iplpdn@nri.reston.va.us
To Subscribe: iplpdn-request@nri.reston.va.us
Description of Working Group:
The IP over Large Public Data Networks Working Group (IPLPDN
WG) will specify the operation of the TCP/IP protocol suite
over public data networks (PDNs) such as SMDS, ISDN, X.25
PDNs, and Frame Relay (FR). The working group will develop
and define algorithms for the resolution of IP addresses and
for the routing of IP datagrams over large, potentially
global, public data networks.
The IP over SMDS Working Group has defined the operation of
the Internet protocols when SMDS is used to support
relatively small virtual private networks, or Logical IP
Subnets (LISs). Issues arising from public and global
connectivity were delegated to the IPLPDN WG.
The IPLPDN WG will also continue the work of the Private
Data Network Routing Working Group (pdnrout) on X.25 PDNs.
This work will be extended to include call management and
the use of the ISDN B channels for the transport of IP
datagrams. Address resolution and routing over Frame Relay
will also be discussed.

Internet Monthly Report October 1990
5) Report from the Network Management Area and Directorate (from
Chuck Davin/MIT):
This month the membership of the SNMP Network Management
Directorate is in place, and the board will organize itself at the
December IETF meeting.
Ted Brunner (Bellcore)
Jeff Case (University of Tennessee)
Chuck Davin (MIT)
Frank Kastenholz (Racal Interlan)
Keith McCloghrie (Hughes LAN Systems)
Dave Perkins (3Com)
Marshall Rose (Performance Systems International)
Steve Waldbusser (Carnegie Mellon University)
Steve Willis (Wellfleet Communications)
The board will serve as a focus for broad community input into the
development of SNMP network management within the IETF. Its
responsibilities will center on guiding and reviewing the MIB
development activity, on assuring that individual MIB activities
are consistent and complementary one with another, and on
overseeing continued growth and evolution in the management
architecture.

BARRNET
-------
Nearly 150 persons from over 75 organizations attended BARRNet's
first annual workshop for current and prospective members on
October 29th. The workshop was held at Stanford University, where
BARRNet's Network Operations Center is located. Attendees learned
about BARRNet's organizational and technical evolution, resources
that are available on the Internet, simple troubleshooting
techniques, and more.
Six new members were approved in October, bringing the total number
of BARRNet members to 75; of these 75, 60 are currently connected.
Two new connections were made in October, including the first 9600
bps dedicated line as part of the low-speed services expansion (see
below).
BARRNet staff has been assisting local universities and community
colleges to prepare applications for NSF grants for Internet
connections. Five Bay Area institutions and college districts have
completed and submitted proposals to date.
BARRNet's low-speed host connection service trial is underway with
9600 bps dial-in connections to dedicated ports as the first
"production" service.
The succeeding phases of the low-speed service availability are
being developed and the first 9600bps dedicated line connection was
installed in October. Lab evaluation is underway of equipment for
asynch host connection at speeds up to 38.4kbps using 56kbps
synchronous digital lines with DSU/CSUs that provide synch-asynch
conversion. These low-speed digital circuits are very favorably
priced by Pacific Bell as part of their "Advanced Digital Network"
(ADN) offering.
Installation has been continuing on the MCI DS-3 microwave link
that will carry traffic from BARRNet to the upgraded high-speed
NSFNET backbone. The digital radios, antenna and all microwave
plumbing have been installed and the balance of the equipment and
activation are expected by the fourth week of November.

Internet Routing
There now exists a complete implementation of version 1 of the IDPR
protocols. After performing extensive unit testing at our
respective sites - USC, SAIC, and BBN, we are currently integrating
all of the software developed at the three sites. Thus far, things
are working well and interoperating, including, for example, the
two distinct implementations (intra-kernel and extra-kernel) of
IDPR message encapsulation and forwarding. We are looking forward
to testing in DARTNet, once we are satisfied with our integration
tests. However, we are also pursuing alternate testing
environments, in the event that DARTNet may not be ready this
month.
INTERNET O&M / ICBNET INFRASTRUCTURE
The routing of traffic between the RSRE, STC, WPC, and NTA ICBNet
nodes and destinations in the US was modified this month to use the
new path provided by the 384 Kbps US/UK "fat pipe". Routing via
the fat pipe path has been stable. The 64 Kbps RSRE-BBN line,
which had previously provided US connectivity from those nodes, is
currently scheduled for termination on 30 November.
The first operational video conferences involving the new
conferencing site at University College London (UCL), and routed
via the US/UK fat pipe, were held this month. These included a
fat-pipe Policy Steering Group (PSG) meeting held at DARPA and UCL,
and an extended demonstration of video/voice connectivity to UCL
from the Interop show in San Jose, CA.
The TWBNet gateways and WPS were removed from the SRI site this
month. This change is associated with the coming addition of a new
"southern loop" to the TWBNet. SRI's ongoing IP connectivity to
the TWBNet will be provided via BARRNet.
Steve Storch and David Waitzman attended the ICB meetings held at
SRI and RIACS on 29/30 October.
Terrestrial Wideband Network and ST/IP Gateway
This month, the ST Gateway and Terrestrial Wideband projects
supported nine conferences and 3 days of demonstrations at the
Interop Tradeshow. Seven conferences were held between two sites,
two were between three sites. The RIACS site hosted its first
video conferences, including a conference for the ICB
Westine [Page 11]
Internet Monthly Report October 1990
(International Collaboration Board.) The Interop demonstration
involved voice/video conferencing between San Jose and UCL, London.
Conferees included Mark Pullen , Phil Gross, John Laws and Peter
Kirstein. Meetings were held to discuss Simnet applications,
ICBNet, connectivity to the UK, and various IETF working group
topics.
In the future months, a new "southern loop" will be added to the
TWBNet. This will provide added robustness in the form of an
alternate path between the east and west coasts and will also allow
shorter tail circuits to Southern sites such as Ft. Rucker and Los
Alamos. Current plans call for Wideband Packet Switches (WPSs) to
be installed in Mobile and Albuquerque.
Jil Westcott (westcott@bbn.com)
CERFNET
-------
Over the next few months several sites will be added to CERFnet.
DIALn' CERF continues to be a popular alternative for companies
with lower start-up needs. Since its installation, it has greatly
increased the number and types of sites accessing CERFnet and the
Internet.
Local installations
A 56 kilobits-per-second (kbps) link to Pepperdine University in
Malibu was installed on October 25. A link to Aerojet General in
Azusa was installed on October 27. The link to Aerojet was
completed using an existing 56 kbps link from Aerojet to the San
Diego Supercomputer Center. A 56 kbps link to the United States
International University in San Diego was installed on November 1.
Other sites scheduled to be installed in November and December are
Santa Monica College, Fullerton College, and Loma Linda University
and Medical Center.
International connections
In the final stages of planning are two international links to
CERFnet. The Federal University of Rio de Janeiro (UFRJ) is
expected to be online by February or March, 1991.
The connection between CERFnet and UFRJ is intended to provide,
among other things, Internet access to a regional network of
research institutions located within the state of Rio de Janeiro.
Initially nine institutions will be connected to this local
Westine [Page 12]
Internet Monthly Report October 1990
network. These are: Brazilian Center of Investigating Sciences
(CBPF), Fundacao Oswaldo Cruz (FIOCRUZ), Institute of Mathematics
Pureand Applied (IMPA), Polytechnic Institute of Rio de Janeiro
(IPRJ), National Laboratory of Computer Science (LNCC), Pontificial
Catholic University of Rio de Janeiro (PUC-Rio), State University
of Rio de Janeiro (UERJ) , Federal University Fluminense (UFF), and
the Federal University of Rio de Janeiro (UFRJ).
Three of these institutions (CBPF, IMPA, and LNCC) are laboratories
of the National Council of Scientific Development and Technology,
which is the equivalent of the National Science Foundation here in
the U.S. Two are federally funded universities (UFF and UFRJ) and
FIOCRUZ is the laboratory of the Federal Health Ministry.
Also, the CICESE Institute located in Ensenada, Mexico is expected
to be onlinein February or March, 1991. The institute will have a
56 kbps satellite link to the San Diego Supercomputer Center.
Other news
In October, CERFnet exhibited at the INTEROP '90 tradeshow at the
San Jose Convention Center. CERFnet was awarded the INTEROP
Achievement Award for the best network in the Service sector.
The installation of DIAL n' CERF was completed in August. Today
over 70 users are subscribing to DIAL n' CERF.
In early November, POP (Post Office Protocol) will be implemented
on DIAL n' CERF making it more convenient for users to receive
their electronic mail.
CERFnet will host the seminar, Introduction to TCP/IP Protocol
Suite, instructed by Dr. Douglas Comer, on January 30-31, 1991. For
more information contact Karen McKelvey by sending e-mail to
karen@cerf.net.

INTERNET CONCEPTS PROJECT
Bob Braden organized and attended a one-day IAB meeting held in
conjunction with Interop '90. He also delivered a talk at Interop
on future developments in the Internet. In October, RFC-1185 "TCP
Extension for High-Speed Paths", written by Braden with Van
Jacobson and Lixia Zhang, was finally published. This RFC
documents an extension to TCP, invented by Van Jacobson, to extend
the region of TCP reliable delivery to very high bandwidths. This
extension can also be used to relax somewhat the requirement for
enforcement of Time-to-Live in packets.

MULTIMEDIA CONFERENCING PROJECT
Packet multimedia conferencing made it to the InterOp show this
year! With a little help from ISI, BBN put on a demonstration of
the teleconferencing system in operation between the show booth and
University College London and with BBN in Cambridge, MA. The demo
went smoothly and was well received.
This month the SPARCstation version of the packet video host, PVP,
was able to run real-time video data through the HSIS board (the
High Speed Interface for the S-Bus), thanks to Van Jacobson's HSIS
device driver. Another milestone was that PVP and the packet voice
host, VT, were able to run simultaneously in the same SPARCstation
machine. In addition, PVP was extended to use not only the new
method for conference initiation using the BBN Host Control
Protocol, but also either of the old methods -- mimicking VT
connection state or operator keyboard commands. Peter Kirstein
from UCL visited ISI to learn about our implementation of the
packet voice and video software.
Eve Schooler attended the Computer-Supported Cooperative Work '90
Conference in Los Angeles, CA, October 7-11, and Annette DeSchon
presented a seminar entitled "Overview of the ISI Multimedia
Conferencing Voice Terminal (VT) Program" at ISI on October 18th.
After a long time in development, the ST protocol specification was
expeditiously processed by the RFC editor and has now been released
as RFC 1190.

Please excuse the fact we have not submitted a report for several
months. This was due to the involvement of the network staff in
the large and important task of relocation and transfer of JvNCnet
from JvNC to Princeton University. All the staffs' efforts,
especially the collaboration between engineering, operations, and
network installation and maintenance groups, assured a smooth
transition and our users saw very little interruption of services.
September's network availability reached 99.82%, the month we
actually became settled at Princeton University and the highest
availability for the year September 89 to September 90. The
average uptime for the period May to Sept. 1990 is 99.40%. Traffic
statistics are also provided.
Availability Traffic (in Billion packets, input)
May 99.50 2.3
June 99.55 2.3
July 98.88 2.6
August 99.15 2.8
September 99.82 2.9
The largest percentage of traffic increase occurred in May with 15%
over April, and July with 13.4% over June and the average amount of
traffic for the same five months is 2.58 billion packets. NEARnet,
Princeton, Rutgers and NORDUnet have continually contributed the
largest portion of JvNCnet traffic.
Line utilization statistics
Based on the number of days in each month, line utilization program
tracks peak, average and exceeded threshold (ET). ET is the

exceeding the line utilization low threshold. The low threshold is
established at 75% for 56 kbps line (changed to 50% starting
September 1990), 15% for T1 (1.544 Mbps line), and 4% for Ethernet.
These statistics are available to the JvNCnet members and indicate

the high utilization for each line and offer an efficient
evaluative tool for our engineering group to determine a site's
performance and load on the JvNCnet and to the JvNCnet members to
ascertain the need for upgrade.
Network servers (NISC.JVNC.NET and R2D2.JVNC.NET) migrated to SUN 4
RISC platforms providing name server, boot server and NICOL server
functions. R2D2 resides on the Sun Sparcstation and is the SNMP
server as well providing the above-mentioned functions. NETMON and
NETLOG, monitoring and logging applications, were installed in two
Network Operations Center Sparcs along witha variety of X-based and
systems resources. Ford and Zaphod EGP peers received fast-
switching MCI interface cards and all routers run cisco 8.1.
Charles Hedrick of Rutgers University helped the engineers to
upgrade all routers to 8.1. Version 8.1 has significantly
strengthened reliability and response time, while eliminating
transient routing loops caused by line flaps. In order to provide
transparent service to the users, duplication of the gateways
(Ford, Zaphod, Hotblack, and Zarniwoop) and the NSFnet was
performed and then placed in the new location. The old NSS were
transferred to Princeton as the temporary NSS's replacement.
Princeton now uses an Ethernet gateway. Previously under
Princeton's aegis, the INRIA connection (Swiss and French Network),
with direct EGP communication to the NSS, will be monitored by
JvNCnet.
The JvNCnet Regional Meeting was held on September 26-27, 1990 and
marked the "inaugural" occasion of the JvNCnet incorporation at
Princeton University. Starting the Wednesday afternoon session,
President Harold Shapiro and Dr. Ira Fuchs, Vice President for
Computing both welcomed everyone and chose to state how valuable
and necessary researchers and scholars have for utilizing the
Internet and international links as well as the significant role it
plays in their daily work. Dr. David Farber presented an
enlightening talk about the gigabit network, the current
"experiment" at the University of Pennsylvania and its part in the
NREN project. Dr. Jun Murai, Associate Professor in the Department
of Environmental Information, Keio University, gave an interesting
presentation about internetworking in Japan and described the
research and academic networks in Japan. On Thursday, Mr. Eric
Aupperle, Director of MERIT, provided an update of the NSFnet's
operations and engineering plans and the relationship between DS1
and DS3 networks. Dr. Jane Caviness, the NSF Deputy Program
Director discussed NSF funding issues and national and
international networking. Mr. David Hochman, Acting Director of
the New Jersey Commission on Science and Technology commented on
the commission's positive direction in favoring network enhancement
in New Jersey and achieving its ultimate goal to have every college

This is a report on the past six months of Internet Engineering-
related research at MITRE.
OSI CONGESTION AVOIDANCE
We have just completed our study of OSI congestion avoidance using
the DEC bit scheme. We collaborated on this work with K.K.
Ramakrishnan of DEC. In the bit scheme, the routers set a bit in
the header of packets that arrive at queues whose average length is
one or higher. The receiving TP4 decreases and increases the
credits it gives to the sender based on the bits it receives. This
scheme has been specified in the NIST Implementors' Workshop Stable
Agreements. In 1989, we implemented it in the University of
Wisconsin ARGO TP4/CLNP, tested the implementation in the Internet
Engineering Testbed, and contributed the prototypes to Berkeley for
inclusion in the BSD GOSIP release.
The goal this year was to test the effectiveness of the scheme with
more realistic internetwork configurations and traffic patterns.
The algorithms have been simulated extensively, but with the
exception of our earlier study, their internetwork performance has
not been measured. We have compared the fairness, delay and
throughput performance of the bit scheme with a "baseline"
behavior. In the baseline, TP4 receives a fixed credit allocation
of 8 PDUs, and it responds to a retransmission timeout by backing
its credit down to one PDU until all outstanding PDUs are
acknowledged.
The experiments were:
Intermittent traffic with uni-directional traffic
Two-way constant demand traffic
Westine [Page 19]
Internet Monthly Report October 1990
Mixed file transfer/remote login traffic
Mixed TCP/TP4 constant demand traffic.
As part of this task, we have also developed a TP4 module for the
MIT Simulator. It includes congestion avoidance and supports mixed
traffic scenarios. A technical report on the OSI internet
performance experiments is not yet available for public release.
Our notable general conclusion is that the DEC algorithms are
effective and can be implemented efficiently (about 20 instructions
in the router). We are preparing an IETF plenary presentation on
the bit scheme study. TP4/CLNP will soon have regular users in the
Internet and we are concerned that their implementations will not
behave well facing Internet congestion. We are also working on
several research and conference papers.
RATE-BASED TP4
In the last half year we have extended the ARGO TP4 and CLNP in a
prototype that implements the Flow Protocol defined by Lixia Zhang.
The TP Connection Request Quality of Service parameters are used
for the Flow Control Protocol exchanges. We have begun to analyze
the performance of the prototype. The experiments were:
Two-way traffic
Unequal path traffic
Increasing utilization
Preliminary results are that Virtual Clock, the router's service
discipline, is efficient in the kernel device drivers, and that the
algorithms benefit performance.
X.400 PERFORMANCE
We have just completed a proof-of-concept prototype to test the
applicability of using a full GOSIP stack in the tactical
environment - an environment characterized by low bandwidth, noise,
and loss. This initial study focused on low bandwidth. We ported
the Wisconsin ARGO X.400 software to a MicroVaxII on the MITRE
Internet Engineering Testbed. The MicroVaxII was already running
the rest of the Wisconsin stack. A Testbed LANs was configured
into two sections so that traffic between the sections would always
be routed through gateways connected by a SLIP line. In actuality,
all hosts in the test, including the gateway hosts, were on the
same LAN (so we could monitor them from one promiscuous Ethernet
interface and obtain one-way wire times). However, from the user
Westine [Page 20]
Internet Monthly Report October 1990
and host viewpoint, each section was a separate LAN connected by a
low-bandwidth transmission medium. We built an event driven
message generator that used the ARGO X.400 application to send
messages between hosts on each section. Experiments were run with
the SLIP line having a baud rate of 600 baud and 4800 baud. The
experiments were also run with and without the use of our OSI
Congestion Avoidance implementation. Performance data was gathered
from logs kept by the ARGO implementation, and from data gathered
by the MITRE monitor program OSI trace. OSI trace, which previous
to this project parsed TP4 and CLNP Protocol Data Units, was
extended to parse session protocol data units and to dump 61 bytes
of the application message protocol data unit. This prototype
indicated that even with a low bandwidth, lower layer transmission
was not a major factor in message delivery times, provided
congestion avoidance was used. We concluded that given proper mail
queueing and connection strategies, and the use of OSI Congestion
Avoidance, the full GOSIP stack is acceptable for tactical
messaging.
We continue to participate in the University of Wisconsin NASA-
funded X.400 Pilot project. An X.400 mail gateway is running on a
Sun 3/60 in the Internet Engineering Testbed and we have exchanged
messages with Wisconsin. In this Pilot, X.400 is transported over
the Internet by RFC 1006 TP0 over TCP.
INTERNET PERFORMANCE
We presented a paper at SIGCOMM '90 on Random Drop Congestion
Control.
We are beginning a new project to develop visualizations of
performance traces from the Testbed, and produce videos from them.
We have begun a three-dimensional animation of gateway congestion
control data. It is possible to see the evolution of the
clustering described by Hashem in MIT/LCS/TR465. The analysis will
focus on correlations of traffic by gateway queuing and effects of
resource reservation and rate control on the traffic processes.
Traces from our experiments with rate-based TP4 will also be
visualized.

NEARnet held its semi-annual user and technical seminar at BBN on
October 26. More than 160 people attended. Highlights included a
panel on "Introducing the Internet at Your Organization", a
demonstration of user interface software, and a technical workshop
on Internet security. Video tapes of the sessions are being made
available; contact NEARnet for more information.
A leased line to the JvNCnet was installed on October 26. This
will allow NEARnet traffic to bypass the JvNCnet backbone,
alleviating congestion for NEARnet and JvNCnet users and reducing
the hop count between the NEARnet hub and the NSFnet backbone.
This line will be in service until the NEARnet NSS is installed and
accepted early in 1991.
NEARnet announced that a dial-up Internet service will be available
in December. The service will support email, ftp and telnet
connections at 9600 baud, and will provide mail queuing and primary

OARnet T1 Backbone Uses OSPF Routing Protocol
We have recently constructed a high-speed backbone of T1 links for
OARnet. There are now multiple paths between some sites.
Generally, we prefer paths that use the T1 links. Within OARnet we
have been using RIP as our IGP. This has proven inadequate because
routes are determined based on hop-count (distance) rather than
line speed. Another problem is slow convergence.
OSPF, a link-state protocol, was developed by an IETF working group
and is defined in RFC 1131. OSPF supports TOS-based routing,
equal-cost multipath, tagged external routes, authentication, and
area-routing.
OARnet Engineering has implemented OSPF routing for the T1 backbone
covering the Columbus, Cleveland, Akron, and Toledo areas. This
has given us the necessary routing control to effectively utilize
the T1 links. It is still necessary to run RIP in some parts of
OARnet because OSPF has not been implemented by all router vendors.
The borders between OSPF areas and RIP areas require careful
consideration. We plan to use OSPF in all OARnet routers as soon
as possible.

1. Thanks to long hours spent by Mike Davis, Mitch Levin and the
PSI crew, our DARTNET line is now operational. We now have a
working router, and line, but still have not resolved all the
problems with the HSI T1 interface. We have also installed a
SPARCstation on the same net as the router for use as an
experiment host.
2. A fuzzball time server originally from JvNC has been
refurbished with hard disk and configured for operation at the
MIT NSS when installed. This will have a WWVB timecode
receiver and serve the NEARNET populace. Several new public
time servers have popped up in the US, UK, FRG and Australia.
Details can be found in the file pub/ntp/clock.txt on

3. Our fancy cesium clock lost tick and was replaced courtesy of
the US Coast Guard, who along with US Naval Observatory have
been most supportive or our timekeeping activities. Some
analysis of how to improve time-transfer for DARTNET and our
high-speed network now in design suggests the use of a LORAN-C
receiver and disciplined quartz oscillator. Although this
scheme is in use now here and at NTARE in Norway, commercial
LORAN-C receivers are much too expensive for casual use. A
design for an inexpensive LORAN-C receiver as an IBM PC
parasite has been completed and is now under construction.
