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 three cross country Arpanet Inter-Switch Trunk (IST) lines
which send traffic over the Wideband Net saw their first full month
of operation in May. The performance of these lines over most of
the month was less than desirable, but through the combined efforts
of all parties, the Wideband Net and attached Arpanet IMPs were
tuned so that the IST lines can now carry moderately heavy levels
of Arpanet traffic and provide acceptable service to the network
users. During the most recent test, we looped all cross country
land lines which are scheduled to go away in the near future, and
the Wideband IST trunks performed quite well. The traffic levels
during this test, however, were unusually light, so we plan more
tests during high traffic periods.
Westine [Page 1]
Internet Monthly Report May 1988
Delay has been the primary problem in making the Wideband / Arpanet
IST lines perform smoothly. Several additional changes to address
this problem will be fielded in the Wideband Net shortly. Software
to reduce delay in the BSAT host interface, to provide delay
measurements, and to improve monitoring will go out shortly. Also,
a modified hardware I/O interface between the Wideband BSATs and
the IMPs which will reduce delay is also being tested.
SATNET
The SATNET has been very stable through the month of May. We did
not have any unscheduled outages of the SATNET SIMP's or PSP
terminal hardware. The availability of the SATNET was again above
99% from tests run by ISI for all sites but Tanum. The Tanum earth
station has been preparing to repoint its dish to a new satellite
and as a result has been periodically removing the SIMP from the
channels.
The new UCL to RSRE and RSRE to Goonhilly lines are now in place.
The two new links are now 64 Kb Kilostream service and have been
operational for several weeks.
INTERNET R&D
The Internet continues to grow. We are currently at about 435
operational networks.
We have almost completed the Telenet certification of the Butterfly
VAN Gateway gateway X.25 interface. So far we run and passed all
of the tests except for reverse charging. We expect to complete
that series of tests in June and submit the results to Telenet. We
have also completed the development of the Pronet Ring interface
and are in the process of debugging the code.
We hosted a meeting between members of the Open Routing Working
Group and representatives of common carriers. The meeting was
organized by Noel Chiappa. The subject of the meeting was the
Switched Multi-megabit Data Service (SMDS) and issues of the
interconnection of public networks and private internets.
SMDS is a user interface and a subnet requirements specification.
The goal of SMDS is to provide LAN service over a Metropolitan Area
Network and ultimately over a Wide Area Network. The protocol is
services/marketing driven. They appear to want to drive the
technology to meet the requirements.
The interface to SMDS consists of two parts, the SMDS Interface
Protocol (SIP) and the Subscriber network interface (SNI). The SIP
Westine [Page 2]
Internet Monthly Report May 1988
contains 3 (non-iso) layers. Level 3 is the network services
layer. The header uses CCITT E.164 (ISDN) addresses and has
provision for Inter-Lata routing information. This is currently a
Nynex and Bellcore joint project, but it is clear they mean to
expand to include other carriers. The PDU can contain up to 8191
octets of user data. Level 2 provides framing and error detection.
Level 1 uses a DS3 interface. The SNI offers different access
classes and based on the access class, controls the flow rate,
including burstiness. The algorithm used is a leaky bucket
algorithm and assumes that hosts will hold back flows according to
their "credit balances".

Jon Postel hosted the CERFNET meeting at ISI, May 11th.
Two RFCs were published this month.

Resolution for A Multi-Lan System of Ethernets",
May 1988.
RFC 1054: Deering, S., "Host Extensions for IP Multicasting",
May 1988.

Multimedia Conferencing Project
Dave Walden completed the debug and check-out phases of the dual-
mode version of PVP (the packet video software in the Butterfly
machine). This allows the operator to specify via keyboard input
either a Multi-Point or Point-to-Point video ST connection and thus
to direct PVP to to use the corresponding messagecontrol format.
This will enable us to test PVP with the initial version of the
Butterfly ST gateway.
Last month, an unusually high number of video screen glitches in
transmissions from BBN to ISI was observed. Because the error rate
was asymmetrical, a hardware problem was suspected. After testing,
it was found that the errors were due to a defective board in the
ESI at BBN.
Westine [Page 3]
Internet Monthly Report May 1988
The conference control program which runs in a small window on the
Sun screen was used this month to automate conference initiation.
It currently initiates voice connections, although work is underway
for video connections as well. It was expanded to supplement its
local video camera control functions with remote capabilities. In
addition, it was generalized to consider multisite conferencing
scenarios. The eventual goal is for it to merge with the already
existing mmconf program that serves as the conference initiation
mechanism for Diamond multimedia documents.
The conferencing system was used for a tele-meeting of the Host
Requirements Working Group of the Internet Engineering Task Force
on May 18th. The all-day meeting was conducted without headphones
and relied upon the performance of an echo cancellor. The sound
quality of this set up received mixed reviews which has warranted
further investigation.
Brian Hung began the first phase of the echo canceller test. This
includes the simple feed through of near-end serial mu-law data to
parallel mu-law output port, plus the conversion of near-end serial
mu-law data to linear and from linear back to mu-law before writing
the data to the parallel output port.
Currently Brian is determining the echo response from our 4-to-2
wire hybrid due to far-end signals. The determination of this will
enable him to devise a near-end speech detection mechanism to
inhibit the updating of the tap weights while a near-end signal is
present.

Annette DeSchon and Walt Prue attended the TCP Performance Seminar
in Monterey, Ca. on May 9-10. They presented this material to an
ISI audience on May 19th.
Annette DeSchon continued work on Background File Transfer (BFTP).
BFTP is now able to resume the transfer of multiple files in the
middle of the list, following a loss of network connectivity or the
crash of either the source or the destination host.
Bob Braden served as chair of the IETF Working Group on Host
Requirements, May 18th, and worked on editing the draft document
the group is putting together. The current draft is 80+ pages, and
incorporates text written by 6 people. The group held a one-day
video teleconference between ISI and BBN to discuss the document;

Infrastructure:
Kirstein and Crowcroft attended the SATNET and Infrastructure and
ICB meetings at FGAN, Bonn, West Germany. A number of important
issues concerning multi-agency International Network
Interconnection were discussed. Some members of the FRICC were
present, and contributed to a lively discussion on policies for
interconnection and routing.
The possible replacements for SATNET, which will be decommissioned
fairly soon, were also discussed at great length. Watch this space
for developments.
Westine [Page 5]
Internet Monthly Report May 1988
Reports on a wide range of experiments carried on over the
existence of SATNET should become availble fairly soon.
Research:
A modified implementation of the IEEE 802.1 addendum D draft MAC
level routing algorithm is now complete, and undergoing extensive
tests for robustness. The algorithm seems to be reasonably stable
under node outages and recovery. A number of minor errors were
uncovered in the version of the draft standard we were working
from.
John Crowcroft (jon@CS.UCL.AC.UK)
UNIVERSITY OF DELAWARE
----------------------
1. Jeff Simpson is studying hierarchial routing algorithms with
the intent of applying these to an interdomain routing
protocol. The goal of this project is to improve the use of
connectivity over existing hierarchial algorithms, while
maintaining reliability, robustness, and autonomy of
individual systems.
2. Paul Schragger devised a simple network simulator to examine
two proposed transport-level congestion control/avoidance
schemes. The simulation has shown that either scheme alone is
stable, but the two implemented together appear to become
unstable in a number of cases. This behavior has instigated
research into providing a mathematical model of network
communications based on digital feedback-control concepts
providing a uniform analytical approach to predict the cases
of flow instablity.
3. A concerted effort was made to resolve continuing performance
problems between NSFNET and ARPANET hosts. Through the kind
cooperation of the six NSFNET Backbone site operators, current
configuration files were collected and stashed in a directory
at a mutually trusted place. This exercise alone turned up a
number of inconsistencies, most of which were resolved and
fixed. The configurations were checked against the current
routing information kept by the Backbone fuzzballs and the
Internet Operations Center and other discrepancies were found.
The most serious problems appear to be failure to switch the
default net when the ARPANET path breaks (UIUC) and excessive
route flapping (NCAR).
Westine [Page 6]
Internet Monthly Report May 1988
4. Previously reported problems with excessive route and metric
flaps in EGP updates from the core system persist. Some of
these can be explained by the fact not all EGP core clients
patter with all three EGP core servers; however, interesting
anomalies have been observed where routes have been "captured"
by one client when another client was squawking a lower
distance, which clearly implies something is badly broken
somewhere. Further quest was temporarily suspended pending
the end-semester rush.
5. The Network Time Protocol (NTP) community continues to grow,
with new servers online at MIT and planned for DECWRL and
NASA/AMES. Spring thunderstorms glitched some clocks and
occasional circuit outages affected others; however, there
were no known cases where these events caused timewarps in
hosts complying with the peerage rules suggested in the
documentation.
6. Effective 5 July, the University of Delaware is to be
disconnected from the ARPANET, but will continue service via
SURANET. Our campus administration has agreed to upgrade the
SURANET access line to T1 speed and to expand the existing 3-
node 80-Mbps fiber ring to over a dozen nodes. Our frisky
fuzzballs will remain connected to the ARPANET and everything
else in town, but will not carry regular campus traffic.
7. Dr. Mills attended a meeting of the National Security
Telecommunications Committee at NAS Headquarters in
Washington, DC. A report covering issues in reliable
telecommunication network synchronization is now in
preparation.

UCAR/BBN LABS NNSC
Since the Domain Tutorial in April, the NNSC has been responding to
requests to perform backup domain service for NSFNET sites.
Craig Partridge chaired the second meeting of the MIB Working Group
of the Internet Engineering Task Force. The group released a
proposed Internet standard for the Structure of Management
Information and the MIB itself. These are now available as IETF
IDEAS on sri-nic.arpa. The comment period on them ends June 17th
(please direct all comments to craig@nnsc.nsf.net).
In Ann Arbor, Craig attended a meeting with Merit, IBM and Guy
Almes of Sesquinet to discuss issues related to network management
on the new NSFNET backbone. Karen Roubicek spoke about NNSC
activities at the biweekly NSFNET Managers' Meeting and met with
the NSFNET backbone Information Services team to discuss providing
complementary information services to the NSFNET community.

CORNELL UNIVERSITY THEORY CENTER
The version of gated that had previously been available as a beta
release is now the offical release. This release mainly fixes and
enhances gated's EGP processing.
The majority of the gated work for support of the new backbone is
done, including the documentation. Gated and the EGP code in the
NSSs is undergoing testing at Merit and IBM with some further
testing to be done at Cornell starting in a few days.
The growth in traffic of NSFNet, as indicated by the following
traffic totals, are most significant considering the problems
NSFNet has experienced during this six month period. The complete
traffic reports are available from Doug Elias at Cornell.

NEW NSFNET BACKBONE
The NSFNET backbone project remains on schedule. Seven of the Nodal
Switching Subsystems (NSSs) are installed and online as of May 31.
These NSFNET sites are Ann Arbor, Boulder, Ithaca, Lincoln, Palo
Alto, Princeton, and San Diego. The other six are on the test
network at Yorktown Heights (IBM), Reston (MCI), Milford (IBM), and
Ann Arbor (Merit). The two network partitions are linked in Ann
Arbor. Over the next week, the remainder of the backbone sites are
scheduled to come online. By June 10, all 19 NSSs should be
installed and exchanging IS-IS routing packets.
Central to full connectivity for the NSFNET backbone is the
software developed for the NSSs. For routing within the NSFNET
core, the NSS code incorporates the IBM adapted ANSI IS-IS Intra-
Domain Routing Exchange Protocol, which uses a Shortest Path First
(SPF) algorithm for internal routing. These IS-IS packets are now
being exchanged between the operational NSSs.
Westine [Page 9]
Internet Monthly Report May 1988
Currently, gateways at Cornell (Unix), SDCS (VMS), NCAR (Unix), and
JVNC (Cisco) are running the Cornell Gateway Daemon (gated)
developed at Cornell University. In addition, initial tests were
done using Proteon gateways.
The next step in phasing in the "new" network is to improve the
routing interface between the RCPs and other local gateways via the
External Gateway Protocol (EGP). This testing is being done as more
mid-level networks are in the process of adding Ethernet
connections between the NSSs and their local networks.
In addition to NSS development, the network management system for
the new backbone is being readied for operation. Netview and
Netview/PC have been installed and configured at Merit's Network
Operations Center (NOC) in Ann Arbor. Testing is proceeding on
Simple Gateway Monitoring Protocol (SGMP) which will be used to
monitor network traffic, routing tables, and link status on the
backbone. SGMP testing is being done on the experimental network by
researchers at Yorktown Heights with the assistance of Jeff Case
and Ken Key of the University of Tennessee.
File Transfer Protocol (FTP) is now available on the IBM 4381/Q14
Information Services machine known as NIC.MERIT.EDU (35.1.1.48).
FTP allows users to transfer both ASCII and binary files to and
from foreign hosts. Files may now be retrieved from the
Merit/NSFNET IS machine via anonymous FTP.

The NSF node at NCAR on the new NSFNET backbone was the first one
to be operational and be tested. At this point it is directly
attached to the USAN ethernet backbone, but plans are to isolate it
on a stub ethernet with a cisco gateway to the USAN AS.

Our ARPANET PSN is online and operational. Our gateway machine, a
MicroVAX II using an ACC5250 interface, is 10.1.0.26
(lola.sdsc.edu). The line to UCLA is still not terminated in the
remote PSN.
The new NSFnet NSS has been assembled at SDSC. It is now
exchanging packets with other parts of the new net. We are
exchanging EGP information with it.
The p4200 continues without any anomallies. We hope to soon
upgrade it with Proteon's newer CPU, Ethernet cards (a pair), and
level 8.0 software.
The University of Hawaii converted their SDSCnet (MFEnet protocol)
line to a p4200 link. Currently our single p4200 is gatewaying
BARRnet(56), Hawaii(56), NWNet(56), Salk Inst.(T1,IP&DECnet),
SDSC(E-net), UCSB(56), and UCSD(2nd E-net).
We attempted to move our GATED functions from our small SUN (3/50)
to one of the VAX's during May. The SRI MultiNet software was very
unstable when used in the active mode. The SUN is again carrying
the load.

BARRNET
(January - April)
This report briefly covers BARRNet actiivity since January, at
which time we were not yet exchanging routing information with the
NSFNET backbone, except for selected supercomputer destinations.
In February-March, parallel efforts at SDSC and within BARRNet to
permit advertising NSFNet routes into and out-of BARRNet without
breaking local routing and reachability elsewhere culminated in
Westine [Page 11]
Internet Monthly Report May 1988
activation of BARRNet as a "real" regional NSF network. However,
various routing and performance muck in the easterly networking
domains delayed activation of BARRNet route exchange for a while to
avoid making matters worse. By the end of March, however, BARRNet
sites were exchanging routing with the other regionals and
supercomputer networks and general BARRNet/NSFNet connectivity was
achieved and being used within the constraints imposed within the
individual member networks. Stanford, for example, has limited
NSFNet routing exchange to selected remote supercomputer networks
because its internal subnet routing systems must be substantially
modified to permit generalized external internet route selectivity
from within campus.
Also in March, the first BARRNet Annual Report was submitted to the
NSF, covering the period from award of grant to January 31, 1988.
Copies are available on request from gd.why@forsythe.stanford.edu.
During March and April, technical planning has focused on
preparation for the new NSFNET backbone connection. The BARRNet
Technical Committee has decided on a BARRNet/NSFNET NSS connection
configuration consisting of:
(a) a subnetted LAN to which the NSS and SU BARRNet gateways
attach (must be a single LAN for both with only 1 network
number in use on the wire).
(b) the NSS is told the LAN is NOT subnetted.
(c) the NSS is told explicitly what broadcast address to use on
the LAN (which of course is the subnet IP broadcast address).
(d) the NSS runs EGP but not RIP.
(e) any SU campus gateways attached to this net will need to do
proxy ARPs for SU hosts. BARRNet will obtain its own AS number.
Planning for additional member sites is actively underway....the
first of which is expected to be LLNL (Lawrence Livermore Labs),
hopefully in June. Plans for upgrade of BARRNet backbone
facilities to higher performance routers to support membership
expansion have also been approved by the technical committee and
consortium members. This will be achieved by substitution of
existing router components into stub networks as new members are
added. BARRNet representatives also participated in the Federation
and Net'88 meetings.

MRNET
During May, NSFnet appeared to be more reliable than during April,
but it is still not without problems. Some users report
difficulties regularily, while others seem to be able to use NSFnet
without much difficulty. Because traffic can be routed either
through NSFnet, or through ARPAnet, it is often difficult to
determine the real source of problems that are reported.
One ethernet controller on the Proteon router failed during May,
and is currently being repaired. The MRNet technical committee is
going to try to more clearly identify the problems being
encountered with NSFnet; hopefully more data will be available for
our report next month.

SESQUINET
The complete initially proposed SesquiNet configuration, now
augmented by Prairie View A&M, has been operational now for several
months. The following campus networks are being served, and are
advertised via EGP to the 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 serial line from NSFnet/NCAR to SesquiNet/Rice has been
operational for several months, and routes to SesquiNet via NSFnet
are now being advertised. Performance is very good.
Our smoothest Arpanet experience came during the early part of May
when our cisco Arpanet support had been debugged and our IMP and
lines were performing well. During the middle of the month,
however, we were disconnected from our IMP, probably never to
return. For a week we used only the interim NSFnet for external
connectivity; this gave us good connections to many sites and
inadequate connections to others. In late May, through the
courtesy of Merit, our nets were advertised by the Arpanet gateway
at Merit, and our connectivity to the Arpanet was radically
improved.
Our new NSFnet Backbone gateway is being assembled as I write, and
we will working this month to bring it into operational use within
Sesquinet.
We will soon resume our testing cisco's support for dual protocol
(IP and DECnet) routing.

1. The NSF FY'88 award arrived late in May. Pursuant to this, we
have initiated the paperwork to pay a number of outstanding
bills.
2. We are in the process of setting up interviews for the Westnet
Technical Support Position. We presently have narrowed the
field down to three excellent candidates. Interviews will
commence on June 9, 1988.
3. David C. M. Wood of the University of Colorado at Boulder has
been testing with Guy Almes of Rice University cisco's
implementation of EGP. To date, everything appears to be
working well.
4. The installation of the IBM NSS at the University of Utah is
proceeding. Estimated power-up is Friday, May 27, 1988. The
cisco to be connected to the NSS via an Ethernet is apparently
an optimal configuration for safe testing as it has only one
Ethernet connected only to the NSS with a Class C address.
Brigham Young University has volunteered to serve as an
initial test site.
5. We have, for the first time, collected some statistics (albeit
primitive) from the Westnet cisco Gateways. Results indicate
that the circuit between NCAR and the University of Colorado
at Boulder experiences very heavy use, and the indication is
that it is saturated for a good portion of the eight hour day.
We are investigating upgrading this circuit to T-1 speed.
6. We are vigorously into the planning stage for the Westnet
Steering Committee meeting, to be held in Denver on Thursday,
July 7, 1988. Issue to be addressed include: traffic, status
of the IBM NSS node at the University of Utah, campus network
ing activity, staffing, training, and preparation of the NSF
renewal proposal.
