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).

SATNET
The SATNET's performance was very good during the month of January.
There were no major unscheduled outages. A scheduled test of new
SIMP software early in the month reduced the availability of the
SATNET. Tests run by ISI indicate, the Goonhilly site was affected
the most. Its availability was 94%. The Tanum, Fucino and Roaring
Creek sites all had availabilities of 98%.

Internet Monthly Report January 1988
Steve Blumenthal, Bob Hinden, Karen Seo and John Leddy attended the
SATNET/Infrastructure and SATNET Measurement Taskforce meetings at
NOSC, San Diego, USA on 1/11-1/13.
WIDEBAND NETWORK
A number of bugs have been identified and corrected in the BSAT's
processor node and channel I/O device software. Some of these bugs
were responsible for sporadic BSAT system-level restarts and
temporary site connectivity losses which have been observed in
recent months. A BSAT software release with the appropriate
corrections will be distributed early next month.
An effort is underway to determine the sources of unusually large
intersite frequency offsets which have been observed in the
Wideband Network since its transition to CONTEL ASC's transponder
on the Westar-IV satellite. The goal of this activity is to
determine which satellite channel subsystem components are
responsible for the observed site frequency distribution so that
this network parameter can be restored to its nominal range. Too
large a frequency distribution can result in degradations in
satellite link performance.
A coast-to-coast meeting of the End-to-End Task Force was supported
by the Wideband Network and the multimedia conferencing facilities
at BBN and ISI on January 15.
INTERNET RESEARCH & DEVELOPMENT
We completed the development of the software for the Low Cost
Packet Radio (LPR) interface and are now planning the deployment of
Butterfly Gateways for the LPR testbeds.
We shipped the Butterfly Gateway for Ottawa. It is configured for
1822, X.25, and Ethernet.
A fifth Ethernet interface was added to the Purdue Butterfly
Gateway. This brings the total number of interfaces to six.
We started working on the software for the VAN gateways. The main
issue we are looking at, other than the Telenet certification of
the X.25 interface, is how to manage which of the two VAN gateways
will advertise a route to network 14 so as to keep the datagrams
going to the gateway which has an open virtual circuit.
We are also fielding a new Butterfly Gateway software update (Rel.
3.11) which fixes a few bugs which were causing some of the
gateways to restart.

Multimedia Conferencing Project
New color video peripheral equipment was received this month
for use with the Concept Communications IMAGE 30 codec. Until
we receive the codec, the new cameras and monitor are being
tested with our experimental codec. The new setup was used
for a tele-meeting of the End-to-End Task Force; the second
camera, mounted on a copy stand to view printed material, and
the larger monitor were both appreciated. Also for that
meeting we had a Shure acoustic echo canceller at ISI on loan.
This device allowed the ISI participants to listen to a
loudspeaker rather than using headphones. While this was a
clear improvement at ISI, it may have degraded the sound
quality as heard at BBN. More testing is needed with echo
cancellers at both sites.
Steve Casner (Casner@ISI.EDU)
Conversion of the Packet Video Processing program continues in
order to make it work with the commercial Image 30 codec by
Concept Communications. We received some information in mid-
month about some of its operational parameters, and some more
at the end of the month. This should be enough to let us the
Image 30 codec in its currently-microded form.

Gomberg, David A., "A Model of Inter-Administration Network
User Authentication and Access Control", The MITRE Corporation,
McLean, VA.
The purpose of computer communications networks is the controlled
sharing of resources among users. While most research,
development, and standardization efforts in networking have
concentrated on the sharing of resources, the control of this
sharing has received much less attention. Many services must be
provided to ensure that the proper persons and processes, and only
these, are allowed to access the shared resources. These services
are usually referred to as network security services. The purpose
of this paper is to present a model of technical operations for two
closely related network security services: user authentication and
user access control. User authentication is the process of
verifying that persons are indeed who they represent themselves to
be. User access control, as used in this paper, refers to the
process of verifying that authenticated users are authorized to
exercise particular applications at a specific host. However,
access control for specific data (e.g., files) within a host is
considered to be a host operating system function that is outside
the scope of the model. The model is designed to promote
controlled sharing of resources. Particular attention is given to
the problems and constraints raised when users and resources are
within the purview of different administrations.
Chirieleison, Don, "A Communications Protocol for User
Authentication and Access Control", The MITRE Corporation,
McLean, VA.
A model of user authentication and access control has been proposed
to promote controlled sharing of resources among a diverse
community of computer systems and networks. This report describes
a communications protocol that will meet the functional
requirements of the proposed model. This document stands alone as
a protocol specification but does not repeat the theoretical
background contained in the description of the model. The report
on the model should be thoroughly read and understood before
reading this document. The purpose of the protocol defined in this
report is to enable elements of the model to communicate among
themselves. It may be used to enable model elements in separate
machines within an access control domain to interact. It must be
Westine [Page 5]
Internet Monthly Report January 1988
used when model elements in different domains exchange information.
It may also be useful for communication between model elements
implemented as separate processes on a single machine.

Transaction Transport Protocol (TTP)
Paul McKenney has been implementing TTP on the SUN, including
Jim Stevens' ongoing updates to the design. The drivers
have been written so that most of the code can be used on
both the SUN and the NIU (Network Interface Unit of the SURAN
Project).

UCL

Infrastructure:
Direct connectivity from UCL to SATNET may disappear in mid
Febuary, and this may affect availability of hosts. This may be of
concern to anyone who has probes/pingers looking in the European
direction.
We have a latest release of Diamond, and should be running this
very soon. Currently we are running 3.0.
Research:
Work continues on SATNET TCP performance, and has just started on
NETBLT. Currently both TCP and NETBLT are hitting a maximum user
data throughput of around 12 kbps. This would seem to be caused by
a queue limitation, and we are investigating exactly where this
queue limit is. A possible candidate for suspicion is a gateway
bunching packets together and causing a SIMPs receive queue to
overrun.
The Thorn pilot name service is running on all machines at UCL, and
provides full O/R name lookup, including a picture service.
Westine [Page 6]
Internet Monthly Report January 1988
UCL has designed and implemented an awk based database for account,
mailbox and machine configuration management. Distributed access
is via NFS. This replaces a previous relational database system,
which used ISO Remote Operations for distributed access and update,
which was found to be too heavyweight.

UNIVERSITY OF DELAWARE
----------------------
1. Traffic on the NSFNET Backbone continued to escalate
throughout the month, reaching new levels of unimaginable
chaos on 28 January, when two key gateways at U Maryland
crashed, leaving only the gateway and fuzzball at PSC to carry
the entire load. The traffic was so intense and so overloaded
the NSFNET Backbone that it fell into a state very close to
complete system collapse. Radical surgery was performed on the
fuzzball buffer management system to avoid blocking upstream
nodes when storage at downstream nodes becomes so badly
fragmented that the preemption policy is unable to find an
input buffer of sufficient size. Rebuilding the system after
the collapse required crashing nodes from the outside in to
break up congestion and then rebooting the system with the new
software from the inside out.
2. Work continued on robust clock-synchronization algorithms to
improve accuracy and resistance to broken clocks. The fuzzball
NTP implementation was modified to include recording and
retrieval of delay/offset samples collected from neighbor
peers. Using this facility a series of experiments were
performed using the five primary radio clocks now operating at
ISI, NCAR, Ford Research, U Maryland and U Delaware. The data
from these experiments was reduced to scatter diagrams and
processed by a number of candidate algorithms, including the
median-filter algorithm now used by the fuzzball. Examination
of the scatter plots suggested a new algorithm, called the
minimum-filter algorithm, which performs better and requires
less computational support. It was implemented for the
fuzzball and is now in operation at all fuzzball time servers.
3. Further analysis, design and experiment resulted in a clock-
synchronization model using a network of hierarchical clocks
and algorithms evolved from the majority-subset algorithms
suggested in RFC-956, which use a weighted voting technique to
cast out broken clocks. The algorithms were implemented for
the fuzzball and are now in operation at all fuzzball time
servers. In carefully orchestrated tests involving simulated
failures the five primary time servers remained synchronized
Westine [Page 7]
Internet Monthly Report January 1988
to at least one radio clock, even to the point where all five
primary (WWVB and GOES) radio clocks had failed and secondary
(WWV) radio clocks at U Michigan and U Delaware kicked in. In
other tests the algorithms correctly identified and discarded
deliberately broken radio clocks.
4. Work began on a revision of RFC-958, which describes the
Network Time Protocol (NTP), to incorporate the latest
algorithms and models.
5. Mike Minnich and Dave Mills attended the IAB meeting at SDSC
on 11-12 January. Dave Mills attended an NRC meeting on
survivable networks in Washington on 19-20 January.

NSFNET BACKBONE SITES
CORNELL UNIVERSITY THEORY CENTER
Much of this month's work has been dedicated to stabilization of
the NSFNET backbone. Many new networks (see following list) have
been added, even though the backbone performance has been
inconsistent. Major attention is being given to the problem of the
fuzzballs' ethernet interface locking up unpredictably, which in
turn, causes major routing problems throughout the internet. At
this time the fuzzballs lock up several times daily, and this
usually breaks all user telnet connections and times out FTP
transmissions. The users are then forced to reinitiate their
access routines to whatever node they had been connected to. As a
result, the NISC is reporting markedly increased complaints from
the users as well as an increase in use of alternate methods of
connection to CNSF from users throughout the country.
Two people have been added to the staff of the Network and Systems
group. Jeff Honig, who replaces Mark Fedor, watches over the
gateway daemon and handles complex problems relating to keeping the
backbone running well. Martyne Hallgren is working on the Network
Outreach program.
The NISC is running STATSPY, a program written by Bob Braden and
Annette DeSchon, on Cornell, NCAR, and UIUC. STATSPY collects data
on traffic between unique source-destination pairs on NSFNET. This
is the first time this type of data has been collected on the
backbone. Doug Elias is working on a series of analysis and
statisical programs which use as input the data collected from
STATSPY. These programs will compress the data and generate
Westine [Page 9]
Internet Monthly Report January 1988
summary reports. An example of the report generated is shown
below. The data shown only represents Cornell traffic. SRC and DEST
define a unique source and destination pair. With an identified
SRC-DEST pair, #RECS represents the number of times that pair was
found in the data sample. The values under FTP, TEL, SMTP, and
SRC-Q are the actual number of packets of that type seen in the
data sample for that source-destination pair. (FTP - file transfer
protocol, TEL - telnet, SMTP - mail, SRC-Q - source quench). The
TOTAL represents the percentage the total number of packets for
each source-destination pair is over the total number of packets
found in the data sample.

JOHN VON NEUMANN NATIONAL SUPERCOMPUTER CENTER
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.
Monthly Status Overview:
The gateways were available an average of 93.11 % of the time.
This represents an improvement over last month. With the exception
of the Rochester's gateway (which has been having continuous
problems from last month), all the other gateways have been
operational. This month we didn't experience any line problem.
The only link affected was IAS due to a mux power problem which was
corrected promptly, and the TransLAN box at Colorado due to a snow
storm. The PSN is still not connected, at this point we don't know
when it will be.
We are still rerouting all traffic between Penn State and NCAR via
JVNCnet and the University of Colorado. The users are very
satisfied with the access that they now have to NCAR.

Internet Monthly Report January 1988
The new circuits between JVNC, Yale, Wesleyan, Brown, Harvard,
Boston University, Northeastern University, Dartmouth College, and
the University of Massachussetts (at Amherst) will be installed in
April 9th. We expect short after to bring up JVNCnet service to
those institutions, closing the double ring part T1 and part
56kbps.
Montclair State College has been awarded a connection to JVNCnet by
the New Jersey Department of Higher Education, and it is scheduled
for connection by spring time.

The Vitalink Satellite connection between USAN and the Naval
Research Lab in Washington, DC is now in place and has passed the
acceptance testing. There yet remains for the Lab to complete
installation and completion of their ethernet equipment and router.
Severe problems, apparently from buffer preemption on the local
fuzzball, restricted the use of the USAN-NSFnet pathway. The
gateway was observed to fail to pass packets for periods ranging
Westine [Page 12]
Internet Monthly Report January 1988
from 20 seconds to 5 minutes with this condition occuring with
periodicity ranging from 30 seconds to an hour.
By Don Morris (morris@scdsw1.ucar.edu)
PITTSBURGH SUPERCOMPUTING CENTER
Our Fuzzball experienced many problems during January which were
apparently congestion related. The links to each of its network
partners bounced at least daily. Most often the Fuzzball loses its
connection to PSC-GW, even though the ethernet between them appears
to be fine and PSC-GW is sending hello packets as expected. This
link's bouncing has a great effect on the NSFnet as the primary
ARPANET connection is lost for a period of time ranging from a few
seconds to a few minutes and the default route shifts from gateway
to gateway. A new version of software on Jan. 29th seems to have
cleared the problem to an extent, but it remains unresolved. Clock
problems early in the month have abated.
PSC-GW continues to push the limit of 64 virtual circuits imposed
by the ACC 5250 board. Problems with PSN 7.0 software seem to be
resolved for our site. New versions of gated and gated
configurations have been installed in attempts to close back door
routes and stabilize routing.
Early in the month a Proteon gateway was installed at Ohio State
University but remained unconnected to the internet due to line
problems. As of the end of the month, the connection to Ohio State
is working and equipment problems are being resolved at Case
Western Reserve University which will bring them on line. The
local loop on the DS/1 circuit to the University of Michigan is
installed and equipment is being sent there for installation.

Our PSN's first trunk line (to USC/ISI), installed on 29 Oct.,is
still awaiting the Telco folks to come finish testing. The second
line to UCLA has just been installed and is ready for Telco
testing.
Our Proteon p4200 has had its memory increased to 1 meg and is now
running 7.4. The combination has resulted in much improved flow.
The problem with large FTP'd files to BARRnet, thought to be a
Proteon problem, has been resolved to a 1's sensitivity by the
Verilink's.
We have brought up a 56k line to UC Irvine to connect their campus
network to NSFnet. This was via a pair of existing Bridge GS/3's.
They will be put into Gated on 12 Feb by the NSFnet NOC.

MERIT
Merit, MCI, and IBM are making good progress with the preparations
for the new NSFNET backbone. IBM is continuing to work on the NSS
(Nodal Switching Subsystem) software development, network
management, and the deployment schedule. MCI expects all of the
data circuits to be installed by the beginning of April. A piece
of the circuit for the four-node experimental network has already
been installed, with the rest to be completed by the beginning of
February. The three partners continued their regular biweekly
management meetings.
In preparation for the installation of the data circuits and the
NSS's, MCI has conducted a site survey of all thirteen mid-level
sites and IBM has prepared and mailed out a site survey of its own.
We have had discussions with the developers of the University of
Wisconsin's OSI implementation (ARGO) regarding the applicability
of their code to the new NSFNET backbone. ARGO allows an IBM RT/PC
running 4.3/RT to communicate with other computers via the OSI
protocol suite. We have installed the code in two machines here
for beta testing and anticipate further tests via the bridged USAN
satellite network.
We briefed the Internet Activities Board this month on the plans
for and status of the new NSFNET backbone. IAB members also got
copies of the proposal which resulted in our award from the
National Science Foundation to manage the new backbone. In other
liaison activities, members of the Merit Technical Support Group
visited the NNSC at BBN to learn more about their operation and to
pursue our working relationship.
Other Activities:
FTP into and out of MTS (the Michigan Terminal System) is now
working and ready to be released to users. This will allow
Internet users to communicate with our MTS main frames.

MIDNET
Midnet is operating quite nicely. The individual campuses are
making a lot of progress in getting their local area networks
running and connected to Midnet. As a result usage of the network
is increasing all the time. Some users have had some problems over
the last few weeks with timeouts and slow response times but
everyone seems to be getting their work done.
We will have release 7.4 running on all of our proteon routers by
the second week in Feb. I hope to make some use of SGMP when this
happens. Our road show is scheduled for several sites toward the
end of Feb. We believe that this will spur quite a lot of interest
in using Midnet and the resources it gives us access to.

INTERNET ENGINEERING
1) The Chair attended the Internet Activities Board meeting at
the San Diego Super Computer Facility (January 11-12).
2) The next Task Force meeting is March 1-3 at the San Diego
Super Computer Facility. For more information, send a note to
gross@gateway.mitre.org or to ietf-request@gateway.mitre.org.
Proceedings from the November meeting in Boulder are complete
(thanks to Allison Mankin, Mitre) and a limited number of
copies will be available in San Diego. The goal for March 1
is to have arrangements completed so that copies will be
available through the NIC.
3) Since there is a longer than normal period between meetings
this time, we scheduled an offline Steering Group meeting in
DC for the first week of February. The Steering Group is
roughly composed of technical representatives from various
government agencies. A rough outline of the topics to be

Internet Monthly Report January 1988
discussed include:
- A technical agenda for the IETF (to be used to guide
the creation of Working Groups)
- Progress of current Working Groups
- Relationship with other groups (eg, NPAG)
- Meeting dates/locations for the next 4 meetings
- How to deal with growth
4) During a progress report on Internet Engineering Task Force
activities at the IAB, we discussed the efforts to upgrade the
Core EGP servers and some mailbridges with LSI 11/73 CPU's and
more memory. This effort has been spearheaded by Bob Enger
(Contel). Both BBN and I were able to present data that
showed how this simple action made significant short-term
improvements in Internet delay and drop rate. I think Bob and
everyone else involved in this effort deserve hearty thanks.
Bob plans to be at San Diego to give us some more details,
like who were all the gracious lendors of the equipment.
5) Four new IDEAs have been installed at the NIC. They are:
