INTERNET RESEARCH REPORTS
-------------------------
AUTONOMOUS NETWORKS
-------------------
Discussion continues on the subject of resource usage feedback
in internets. D. Estrin and L. Zhang are drafting a related
position paper/RFC. In collaboration with S. Shenker (Xerox PARC
and E2E Rsch Group) we are planning some related simulation
work as well.
Deborah Estrin (Estrin@USC.EDU)
END-TO-END SERVICES

No progress to report this month.
Bob Braden (Braden@ISI.EDU)
PRIVACY AND SECURITY
--------------------
Matt Bishop of Dartmouth College distributed a draft security
analysis of Network Time Protocol to the PSRG for review. This
report is the result of work initiated during joint sessions
between the PSRG and the End-to-End Research Group at the Xerox
PSRG meetings in January of this year, and of subsequent
consultation over the past months between Matt and NTP founding
father Dave Mills.
Russ Housley of Xerox presented his work to date on a security
labelling framework RFC at a workshop on Security Labels for
Open Systems held at NIST at the end of May. A current version
of the draft RFC was recently distributed to the PSRG for
review. In conjunction with this work, Russ has been invited to
speak on a security labelling panel at the 13th National
Computer Security Conference in Washington this October.

Internet Monthly Report June 1990
TIS has begun distributing its Privacy-Enhanced Mail software
for beta test. It is currently in use at TIS offices in
Maryland and California, and a phased distribution to other PSRG
and IAB member sites (NIST, BBN, NRI) is planned for this month.
In the meantime, BBN continues development on hardware and
software in support of the P-E Mail registration process, and
has been continuing to meet with developers at TIS to exchange
and review documentation pertaining to integration issues.
The PSRG will meet in Vancouver July 31-August 3 in conjunction
with the upcoming IETF meeting, and some joint meetings with
IETF WGs are anticipated. An agenda for this meeting will
appear in the next PSRG monthly.

COLLABORATION TECHNOLOGY

No report received.
INTERNET ENGINEERING REPORTS
----------------------------
1. CNRI is developing a database facility for tracking all online
IETF information. When completed, we will be able to provide the
capability to query for general information on IETF (including
logistics information for upcoming meetings), and for specific
information about working groups (including working group
objectives, projected dates for accomplishing objectives, meeting
minutes, and Internet-Drafts). Not only will this provide a very
useful way for interested parties to obtain information about IETF,
but it will also serve as a way to track the activities and
progress of the numerous working groups. As an example, I will
give some information below about IETF activities using tools and
data from the database.
Thanks go to Greg Vaudreuil (CNRI) for developing the database
tools. It is our goal that most of the information now available
in the quarterly IETF Proceedings will eventually be available
through the database tools and reports.
2. The following information about IETF attendance and growth is
from the database.
Westine [Page 4]
Internet Monthly Report June 1990
Attendance for the last six IETF meetings:
- 12th IETF, Jan 1989, University of Texas 121
- 13th IETF, Apr 1989, Kennedy Space Center 112
- 14th IETF, Jul 1989, Stanford University 215
- 15th IETF, Oct 1989, University of Hawaii 138
- 16th IETF, Feb 1990, Florida State Univ. 191
- 17th IETF, May 1990, PSC/SEI/CMU 243
With the exception of the Stanford meeting (which may have been
overly large because of proximity to computer industry), this
appears to represent a steady growth from the around 100 to over
200 in the last year. Total attendance at these six meetings
represents attendance by 500 different persons from 166 different
organizations.
3. Repeat attendance by individuals is high enough to show a
dedicated core of key IETF contributors. There are 23 persons who
have attended all of the last 6 meetings, 28 who have attended 5
meetings, and 46 who have attended at least 4 of the last 6 IETF
meetings. That is almost 100 folks who have attended at least 2/3
of the recent meetings. This is impressive when you realize that
attendance was only just over 100 for 3 of the those meetings.
When the attendees are grouped by categories, we found that about
1/3 were from vendors, about 1/3 from goverment (DoD and civilian
agencies), and over 1/4 from universities and regional network
operators.
4. Perhaps a more important measure of IETF activity is the number
of active working groups and the number of RFCs produced over the
same period. The following list shows the total number of working
groups and the number which actually met at each meeting:
Date Location Total WGs # met
- Jan 1989, University of Texas 12 12
- Apr 1989, Kennedy Space Center 19 17
- Jul 1989, Stanford University 20 18
- Oct 1989, University of Hawaii 19 18
Westine [Page 5]
Internet Monthly Report June 1990
- Feb 1990, Florida State Univ. 38 32
- May 1990, PSC/SEI/CMU 40 33
- current (for UBC) ~50
Notice that the number of working groups has shown a sharp increase
since the creation of the IESG last fall. The IESG first met at
the University of Hawaii. After that meeting, the number of WGs
doubled.
5. During this approximate period, there were over 80 RFCs
published relating to Internet technical activities. Of those
RFCs, around 30 pertained to Internet standards. The IETF
accounted for almost 30% of the total RFCs published and for ~55%
of all RFCs pertaining to standards. The IAB itself, together with
the IRTF, accounted for almost another 30%, meaning that the IAB as
an organization (ie, including IETF and IRTF) accounted for almost
60% of all RFCs published in this period.
6. The current list of IETF working groups by IESG area is given in
Attachment 1. The standard WG abbreviation is also noted. We use
the standard WG abbreviation when naming the online files and
Internet-Drafts.
7. A history of WG meetings and attendance is given in Attachment
2.
8. A version of this information will be presented and discussed at
the UBC IETF meeting.

CERFNET
-------
Connections
Testing on a link to the Federal University de Rio de Janeiro began
in June. The university will be connected to CERFnet in the near
future. The university has a 4.8 kbps connection via New York to
UCLA. Eventually, they will be connected to the San Diego
Supercomputer Center directly.
The Federal University de Rio de Janeiro needs access to the
Internet to communicate with researchers at the Latin American
Center at UCLA and to access online library and database catalogs
such ORION, also at UCLA.
The university currently has BITNET access but would like to
install a direct link to the Internet. Eventually, the university
will serve as a hub for a collection of Brazilian universities that
require access to the Internet. Also in June, CERFnet started to
advertise routes via IGRP to ESNet. ESNet is connected to CERFnet
at the UCLA and Caltech backbone nodes.
Installations
A new industrial member will be brought online in July. Emulex
Corporation, located in Irvine, will have a 56 kbps link to the
University of California, Irvine. Emulex builds TCP/IP terminal
servers, among other things.
Several new sites will begin using DIAL n' CERF in July. Among them
are Stardent Computer, Duke Childrens Clinic, and Baker and
McKenzie.
Westine [Page 12]
Internet Monthly Report June 1990
Quarterly Seminar
CERFnet hosted a seminar on June 5, "The Future of Computing: Fact
and Fantasy" at the University of California, San Diego. This one
day seminar was led by Dr.Stephen Lundstrom. The seminar outlined
some of the important trends in technology, the direction
technological advances need to take, and what capabilities these
new advances will provide.
New Service
CERFnet announced a new product, CERF 9.6, in June. CERF 9.6 is a
subscription service at 9.6 kilobits-per-second (kbps), and
provides an economical alternative for sites with lower startup
needs. This new service eliminates the cost of the gateway box
which reduces the initial startup costs.
A typical CERF 9.6 member will have only one mainframe computer or
similar such as a VAX or MicroVAX. Because there is only one such
computer, a gateway to route traffic is not needed.
Also, CERF 9.6 lets organizations upgrade to CERF 56 (56 kbps) and
CERF 1544 (T1) easily.
CERFnet provided Internet connectivity to the USENIX conference in
Anaheim.
by Karen Armstrong <armstrongk@sds.sdsc.edu>
CICNET
-------
Four major activities have been at the forefront for CICNet during
June: the completion of our FY 1991 Business Plan, the issuance of
our Request for Proposals for Network Management and Operations
Support Services, the directions issued from our Technical Board,
and the announcement by the NSF of a third NSS access point on the
CICNet backbone.
The Business Plan, which is expected to become effective in July,
continues to emphasize the development of end-user applications
rather than simply the deployment of technology. The Plan also
addresses the relationships between CICNet as the regional network
organization and the state or subregional networks functioning
within the CICNet states. We believe that our approach will work
well in this potentially difficult area. Copies of the Business
Plan will be available from CICNet upon approval.
Westine [Page 13]
Internet Monthly Report June 1990
On June 14, the Bidder's Conference for our NOC services
procurement was held in Ann Arbor. Seven organizations were
represented, with an additional three organization not in
attendance indicating an intention to submit a bid. The closing
date for submissions was extended to July 6. A team of four
evaluators will analyze the proposals and make recommendations to
CICNet. An announcement of award is expected in September.
The CICNet Technical Board has created two new task forces: one to
guide CICNet's OSI Technology Integration, and the other to plan
for an experimental DS-3 network within the CICNet region. Linda
Winkler, Argonne National Laboratories, is chairing the OSI task
force. No chair for the DS-3 group has yet been appointed.
Lastly, the NSF has announced that a new NSFNet node is to be
located at Argonne National Laboratories in the Chicago area, and
will provide service to and from CICNet. Efforts have already begun
in the CICNet Network Planning and Design Subcommittee to
accomodate the expansion.

INTERNET CONCEPTS PROJECT
Bob Braden chaired a meeting of the End-to-End Research Group at
CMU in Pittsburgh, and attended an IAB meeting at BBN in Boston.
He also organized and chaired a meeting on the research program on
DARTNET. Work was begun on an RFC, with Van Jacobson and Lixia
Zhang, concerning TCP extensions for high-speed paths.
Greg Finn tested the IP/SQ algorithm using random drop against TCP
for equivalently long file transfers. Interference effects between
IP/SQ and TCP appear small. A first draft paper that describes
IP/SQ performance in the test network setting has been completed.
Paul Mockapetris atended the IAB meeting in Boston, Mass, 28 and 29
June. Joyce Reynolds hosted an IETF meeting at ISI, June 12. Jon
Postel attended the DEC, ANSI and IAB Meetings, in Boston, MA.,
25-29 June.

MULTIMEDIA CONFERENCING PROJECT
Work continues on porting the Voice Terminal (VT) program to run on
a Sun Sparcstation and on upgrading the Multimedia Conferencing
Control program (MMCC) to handle multiple codecs and a variety of
site configurations.
Tim Shepard from MIT LCS visited ISI to learn about the hardware
and software we use for packet video. Tim will use the same video
codec we do, the Concept Image30, to implement packet video on a
386 PC-AT hardware base. We plan to work together so our
implementations can interoperate.

LOS NETTOS
----------
Walt Prue attended the Cisco User Symposium in Redwood City, June
13th and 14th. It gave the attendees a chance to tell cisco what
new products and enhancements we wanted to see from cisco. Cisco
did appear to be taking note of all comments.
Walt Prue attended the Calinet meeting in Oakland June 21st. It
appears that Los Nettos and CERFnet will be able to get backup
routing of our routes through BARRNET to the NSFNET. The DWR T1
line appears to be close to being brought up and will provide a
path to BARRNET. BARRNET has installed OSPF within their network.
This will allow them to install the appropriate routing controls to
make this alternate path safe from long term routing loops.
Los Nettos and CERFnet are still getting only a handful of routes
from the ESnet connection at Caltech and none through UCLA's
connection. We therefore don't use ESnet for any significant load.
Walt Prue (Prue@ISI.EDU)
MERIT/UMNET
-----------
Continuing with our plans to upgrade the statewide network
backbone, Merit staff met with representatives of several vendors
who answered our RFI for backbone router equipment. A
recommendation for router technology will be made shortly.
In the meantime, and in preparation for a faster backbone and
better connectivity for our members, Merit is assisting many of our
campuses in applying for their own network numbers. This process is
proceeding well, and we expect several of our campuses to convert
to the new numbers before the beginning of the fall 90 academic
term. Several workshops and planning sessions have been held with
staff and administrative personnel from member institutions to help
Westine [Page 16]
Internet Monthly Report June 1990
with planning for changeover of campus network numbers.
Expansion of access for educational institutions and research
facilities was part of the Merit Board's mandate after their
special meeting this winter. To meet these new goals, we have hired
new staff members whose main goals are marketing Merit and its
services across the state of Michigan.
Merit central staff are assisting member staffs with user education
issues as well as technical issues, including presentations,
planning for documentation changes, and newsletter articles.

MITRE Corporation
-----------------
This is a report on the past six months and some of the current
activities in Internet Engineering research at MITRE.
OSI TRANSITION
We have produced a prototype implementation of X Windows in OSI.
This prototype implements an Association Control Service Element
(ACSE)-based strategy for mapping X to OSI. It was presented at
the ANSI X3H3.6 meeting in Durham, North Carolina, April 9-10, and
the National MAP/TOP User's Group Meeting in Washington, D.C., May
2-3. With the assistance of Bellcore, the performance results were
also put before the European Joint Network Team.
For our participation in the University of Wisconsin X.400 pilot
project, we have installed the software on a Sun workstation on the
Westine [Page 17]
Internet Monthly Report June 1990
Internet Testbed. In order for the pilot to be Internet-wide, the
participation is with X.400 over TCP using RFC 1006. MITRE will
additionally measure the performance of the X.400 over the
Wisconsin TP4-CLNP in the Internet Testbed.
We are now testing a TP4 module we have written for the MIT Network
Simulator. This has congestion avoidance algorithms and mixed DoD
and OSI traffic cases among its option settings.
INTERNET MEASUREMENT
We have completed a report analyzing performance data collected on
the Integrated Tactical Demonstration Network demonstration. With
traffgen, toptrace, and Slow-start TCP modified to enforce a chosen
sending TCP maximum segment size, experiments were carried out on
the TCP performance available from paths traversing VSAT, TACSAT,
Line of Sight radio, and DAMA links. A paper on the results is to
be presented at the SHAPE Technical Centre Military OSI Symposium
June 7.
INTERNET TESTBED
The East Coast Federal Internet Exchange, or FEBA-East, is going to
change configurations and the Ethernet connecting the MILNET
Mailbridge and NSS 9 will no longer be located at MITRE. The
Defense Communications Agency Internet Testbed has had to find a
new way to reach NSFNET. As of early June, testbed connectivity
will be through a fractional T-1 link with Alternet.
We are using the testbed now to do multiple topology testing of the
DEC-bit implementation for BSD TP4-CLNF. University of Maryland
testing of the UNIX OSPF implementation is continuing.

NEW ENGLAND ACADEMIC AND RESEARCH NETWORK
-----------------------------------------
NSF announced in early June that NEARnet has been awarded an NSS,
which will be connected to the NSFnet at T3 rates. Details of the
installation are not yet final but it is anticipated that the
connection will be established during the fall of this year.
NEARnet is actively investigating the use of dark fiber in its
metro Boston hub, to run at FDDI speeds. This change could be
accomplished in the same time frame as the installation of the NSS.
Shiva Corporation, Banyan Systems, Atmospheric and Environmental
Research Corporation and the Massachusetts Regents Computer Network
were connected to the network during June. NEARnet has experienced
significant problems with the current connections to the NSFnet
through the JvNCnet. The JVNCnet operator is aware of the problems
and is in the process of upgrading its equipment to resolve them.
NEARnet has completed its start-up phase. It reached financial
self-sufficiency at the end of June, demonstrating that high
quality network services can be provided at a cost which is
attractive to members. It will continue to maintain a high
standard of service and to add new services, particularly in the
applications area, that can be of benefit to its members.

NORTHWESTNET
------------
Ron Johnson, Co-principal Investigator for NorthWestNet; Eric Hood,
Chairman of the Technical Committee; and Dick Markwood, Project
Director visited NSF on June 21 to report on NorthWestNet to the
NSF Networking Staff. The presentation focused attention on large
distances that NorthWestNet traverses to serve its constituents and
on the related costs of circuits. The public telecommunications
infrastructure is largely underdeveloped or non-existent in large
areas of the six member states. For example 56 kbps circuits have
not been available in North Dakota and Montana until within the
last month. The presentation also highlighted features of the
NorthWestNet Strategic Plan expected to be completed in July.
The link between Seattle WA and Fargo ND was upgraded from 19.2
Kbps to 56 Kbps on the 28th.

NSF BACKBONE (Merit)
-------------------
The NSFNET Backbone inbound packet count for June, 1990, totalled
3,272,564,511 packets. This is an increase of 3.78% over the May
total of 3,153,325,456 inbound packets. The number of networks
announced on the NSFNET backbone increased to 1639 at the end of
June.
The National Science Foundation announced a $7.9 million expansion
of the NSFNET. In addition to adding three new nodes to the
backbone, data transmission speed on several key links of the
existing network will be increased to 45 million bits of
information per second. The sites that will be linked by the new
higher speed connections are Cambridge, MA, Ithaca, NY, Pittsburgh,
PA, Ann Arbor, MI, Urbana-Champaign, IL, Argonne, IL, San Diego,
CA, and Palo Alto, CA. The new nodes on the NSFNET backbone
network will be located in Cambridge, MA, Argonne, IL, and Atlanta,
GA. The Cambridge node will be at the Massachusetts Institute of
Technology and will connect the New England Academic and Research
Network (NEARnet) to the NSFNET. Argonne National Laboratory,
located near Chicago, will provide connections to ANL and
additional connections to CICnet, which serves institutions in the
upper Midwest. The Atlanta node will be at Georgia Institute of
Technology and will provide additional connections to the
Southeastern University Research Association Network, SURAnet.

The NSS relocation at Ithaca (NSS 10) was rescheduled for the week
of July 1. College Park (NSS 9) is scheduled to be relocated the
week of July 9 and Princeton (NSS 8) the week of July 16. It is
planned that none of the sites will be completely isolated for
extended periods of time as the changes take place. Any questions
may be directed to the regional network or nsfnet-info@merit.edu.
An NSFNET Technical Seminar was held in Ann Arbor, MI on June 21
and 22. Members of the Merit/NSFNET partnership addressed topics
of network analysis and latencies, OSI in the NSFNET, and T3
technology and plans for the NSFNET backbone. Guest speakers were
Van Jacobson, of LBL, on network performance considerations,
Darleen Fisher, of NSF, on gigabit testbeds, Joel Replogle, of
NCSA, on advanced graphics applications, and Dory Leifer, of U of
M, on internetworking with ISDN. A technical meeting for EASInet
was also hosted on June 22.
The process by which international networks register for an IP
address and network status is now facilitated by addressing
requests to IP-register@merit.edu. Foreign nets requesting network
status as a member of CA*Net, JANET, IRIS, Inria, EUnet, EASInet,
DFN or Nordunet are encouraged to use this procedure.
The replacement of IDNX equipment with Cylink ACSUs was completed
and work continues on an OSI implementation. The SRI-NIC and
NSFNET staff have been working to better rationalize the manner in
which Milnet hosts are announced on the backbone. The Border
Gateway Protocol (BGP) has been implemented between CA*Net and
NSFNET, on the link from Toronto to Ithaca. BGP is documented in
RFCs 1163 and 1164.
Glee Cady, manager of Merit/NSFNET Information Services, spoke
about the current state of the NSFNET to attendees of Networking
'90, the Canadian Networking Conference hosted by the University of
Victoria, British Columbia. Eric Aupperle, President of Merit
Computer Network, Inc., represented Merit/NSFNET at the FARNET
meeting. Hans-Werner Braun, principal investigator on the NSFNET
project, and Elise Gerich, of Merit/NSFNET Internet Engineering,
attended the FEPG meeting. Hans-Werner also attended a meeting of
the IAB. Elise participates on a committee with Scott Brim, of the
Cornell University Theory Center, and Tony Hain, of ESnet, to draft
an architecture for the NREN.

UNIVERSITY OF DELAWARE
----------------------
I am proud to say our efforts on behalf of the Internet community have
been faithfully reported each and every month since the inception of the
Internet Monthly Report many years ago. However, our efforts are
primarily to support research and only secondarily to support
infrastructure. The nature of other contributions to this report, as
well as the perceived needs of the readership, have led us to alter the
nature of our own contributions. In future only activities important to
the conduct of collaborative experiments and infrastructure will be
reported. Our research activities and results will be reported as usual
in various technical reports, symposia and archival publications.
No progress to report this month.
