IAB MESSAGE
A. DAVE CLARK CITED
The IAB is pleased to note that IAB member Dave Clark has been
selected by Federal Computer Week as one of the "Federal 100"
movers and shakers in the federal government systems area.
Their citation did not mention Clark's SIGCOMM award last year,
nor his contribution to the development the Internet
architecture that led the IAB to informally title him "The
Internet Architect". The citation in Federal Computer Week
[page S17 of the Feb. 25, 1991 issue] reads as follows:
David D. Clark
Senior Research Scientist
Laboratory for Computer Science
Massachusetts Institute of Technology
You might say Clark is deep in the loop. Since the early 1970s,
he has been intimately associated with the design and
development of the nation's core data communications framework,
first as a developer of the early ARPA network protocols and
more recently as chairman of the Internet Activities Board and
its research task force.
This year, Clark received national attention for heading the
National Research Council committee that produced "Computers at
Risk," a comprehensive study of hazards facing computers and the
data they contain. The report pointed out that computers have
becomer more vulnerable because of poor system design,
accidents, viruses and other attacks. It also noted that the
evolution of computer networks and the growth of computer
literacy have added to the risk.
Clark was one of the developers of token-ring local area
networks which led to current commercial products and was the
origin of the IEEE 802.5 standard for token ring networks. He
has been associated with MIT's Laboratory for Computer Science
since receiving his doctorate from MIT in 1973."
B. UPDATE ON INTERNET REGISTRY AND CONNECTED STATUS
The policies recommended by the IAB in RFC-1174 ("IAB
Recommended Policy on Distributing Internet Identifier
Assignment, and IAB Recommended Policy Change to Internet
`Connected' Status", August 1990) were approved by the Federal
Networking Council (FNC). However, the Defense Communications
Westine [Page 3]
Internet Monthly Report February 1991
Agency (DCA), which funds the DDN NIC, was not willing to change
the registration procedures while a procurement action was in
progress to select a follow-on contractor.
Subsequently, NSF agreed to consider for sponsorship any
networks that wish to be registered under the RFC-1174 rules.
NSF cannot provide a "blanket" sponsorship, since each instance
has to be validated against existing US government policies.
Once the procurement action has been consummated, the
implementation of RFC-1174 will be somewhat easier, since the
global Internet registry functions now performed by the DDN NIC
will have been separated from the DDN registration functions to
be performed under the new contract. The details of
implementation are still being worked out, but the IAB is
confident that the matter is well in hand.
At the January IAB meeting, the IAB reaffirmed that the RFC-1174
registration process is necessary for global registration, to
support an increasingly international Internet.
C. STANDARDS ACTIONS
The IAB has taken the following actions on standards since
January 1991. The actions are in accordance with
recommendations made by the IESG.
* OSI Internet Management MIB II to Proposed Standard.
* IP over SMDS to Proposed Standard
* IP over ARCNET to Proposed Standard

INTERNET PROJECTS
-----------------
BARRNET
-------
Two new 56 kbps connections and one dial-in connection were added
in February, bringing the total number of connected members to
seventy-six.
An initial cutover to the use of the new T3 facilities and NSS was
made in February, but had to be reversed due to bugs in the newest
release of the software for the cisco routers in BARRNet's core.
The bug was causing the system to fail to route traffic over the
previously existing T1 circuits and NSS when the T3 system failed.
BARRNet's Administrative Committee approved the addition of a new
hub site in the South Bay area, probably to be located at Santa
Clara University. This hub, to be implemented in the next 2-3
months, will initially be connected to Stanford University only,
but will eventually become part of a separate South Bay loop
providing redundant T1 connectivity to all sites connected to the
hub.
by Paul Baer <baer@jessica.stanford.edu>
CICNET
-------
The transition to the new CICNet NOC at Ohio State University was
completed on Feb. 14th. As part of the operating agreement with
AT&T and OSU we also began received monthly network traffic and
performance reports. These reports, which are under development by
personnel at AT&T Bell Labs, are providing CICNet with detailed
analysis of network traffic and performance issues.
CICNet held a meeting of its Technical Board on Jan. 31 and Feb. 1.
in Orlando, Florida. The meeting was hosted by AT&T and featured a
tour of the AT&T internal network NOC and presentations by AT&T
personnel on a variety of technical issues.
During February Interim Executive Director John Hankins visited
Minneapolis and made presentations to groups from the Minnesota
Supercomputer Center, the University of Minnesota, and MRNet.
Loyola University Chicago became a member of CICNet during
February.
Westine [Page 7]
Internet Monthly Report February 1991
CICNet has finalized a consulting agreement with ANS. The
agreement, which runs for three months and began on Jan. 1, 1991,
specifies that ANS will provide consulting to CICNet, primarily, in
the areas of general management and strategic planning. Pending
evaluation by the CICNet Board and ANS, the agreement may be
extended beyond the initial three month period.
by John Hankins (hankins@cic.net)
CORNELL
-------
International Connections
Equipment has been ordered for the new lines to NORDUNET and INRIA.
The line to NORDUNET should be in on March 11th; the line to INRIA
should be in on about April 8th. We are currently working out
routing and operations agreements.
Wide-Area Multicasting
At the March IETF we will be presenting our designs for extensions
to OSPF and BGP to route multicast packets over the Internet. This
will be done in the Working Groups for those protocols. For OSPF
we are presenting one solution; for BGP there are several with
increasing capabilities for administrative control but also with
increasing overhead.
Gatedaemon Project
Work was done to support variable length subnet masks, including
updating the core routing table to properly handle netmasks
supplied with route. The routing protocols were updated to provide
netmasks when adding routes. Much of this code was generalized so
it will work with other protocols, but a lot of it is still IP
specific especially when applying netmasks.
Much research into radix tree based routing tables needs to be
done. The BSD 4.3 Reno reduced radix tree is one option as is the
Patricia work done at Network Systems. This recent work will make
it easier to support whichever method is used.
Extensive testing (although only in the RIP/EGP environments) was
done of the work done during the past few months. This has
required cleanup and rewrite of some features, such as redirect
processing and the kernel interface to fix unintended features
(i.e. bugs). A lot of the more recent work is not yet tested.
Westine [Page 8]
Internet Monthly Report February 1991
Constant contact has been maintained with Dennis Ferguson at the
University of Toronto, who has modified the gated BGP v1 to improve
performance and support BGP v2 and v3. The intent is to merge this
code into the current source as soon as it is available. Dennis
claims to be testing his work right now.

CSUNET (The California State University Network)
------
We just completed installation of an additional (CSUNET's second)
path to BARRnet via a T-1 span from San Francisco State University
to Stanford University. This brings the total number of links to
the Internet to four (two T-1 links in Southern California via
CERFNET and two T-1 links in Northern California via BARRnet).
CSUNET is continuing engineering work for the routing paths thru
CSUNET to utilize the new T-1 links across the CSUNET backbone, the
DWR (The California Department of Water Resources) aqueduct T-1
fiber path (CALiNET), and the four Internet paths. This is an on-
going project with BARRnet and CERFnet.
Using the Telenet commercial network to CSUNET X.25, BESTNET
(Argentina, South America) is now able to gain password protected
TCP/IP access to the Internet.
During this and the next few months, CSUNET Access Ports (CAP) are
being upgraded by Network Operations to provide more reliable
student/faculty/staff asynchronous dialup access (up to 9600b/s) to
CSUNET X.25 and IP hosts via X.25 PADs. CAP is available for use
by CSU students and faculty/staff at all of the twenty CSU
campuses.
Upgrades to CSUNET this month include a new AGS+ at CSU Fullerton
and San Francisco State University. CSU Fullerton now is utilizing
the first backbone "ring" T-1 between the Fullerton campus and the
Network Operations Center in Los Alamitos, CA (SWRL). X.25, IP,
DECnet, and AppleTalk are using the new T-1 path.
In order to facilitate early installation of additional T-1 links
in the CSUNET backbone "ring", we are looking at using interim
equipment.

MULTIMEDIA CONFERENCING PROJECT
On February 27th the SPARCstation implementation of VT, the packet
voice host, was used in an audio conference over DARTNET connecting
five sites: ISI, LBL, MIT, PARC, and UDel. Several additional
sites were patched in via an AT&T conference call. The report from
participants was that the technical aspects of the conference went
smoothly and sound quality was good.
For the DARTNET conference, which used no ST-Routers, VT was
configured to send duplicate data packets to each of the sites
Westine [Page 10]
Internet Monthly Report February 1991
participating in the conference. To support multiple connectees
without the use of ST-Routers, some additions were made in the
(partial) ST-I implementation code within VT. The latest version
of the VT source code, which includes these changes, as well as
some bug fixes, is available via anonymous FTP; "vt.120.tar.Z" is
located on "venera.isi.edu" in the "pub" directory. We will soon
make a release of PVP, the packet video host, available through
anonymous FTP as well.
The final pieces were put in place to support multisite PictureTel
conferences with receiver-selected floor control. Because the
PictureTel codec can only display one video stream at a time, we
had already implemented the ability in MMCC, the multimedia
conference control program, to tell PVP which video stream to
display as the user directed. This in itself was not enough.
Whenever a site switched to a new image, the time for the
background refresh to reconstruct the image was too long. We
therefore have enhanced MMCC to instruct the PictureTel codec to
refresh its video image as needed. MMCC also puts the PictureTel
codec into the correct transmission mode (e.g., multipoint or point
to point) depending on the number of conference participants.
Steve Casner visited David Sarnoff Research Center and Sun
Microsystems to discuss possible collaboration on the next stage in
packet video -- scaling up to High Definition. At Sun, a talk was
presented on "Workstation Conferencing with Packet Video".

LOS NETTOS
----------
The T1 line supporting TRW's access location change is due soon.
Pacific Bell was helpful in giving us an accelerated installation
schedule. They are now able to provide B8ZS encoding with no
charge on new installs.
Walt Prue (Prue@ISI.EDU)
MERIT/UMNET
-----------
Just before the end of the month, we sent our grant proposal for
upgrading our network backbone out to the NSF. As part of our
progress toward that upgrade, Western Michigan University is now
linked to our network using IP routers rather than the older PDP-11
Westine [Page 11]
Internet Monthly Report February 1991
based network nodes.
In affiliate news, we have added several new affiliates throughout
February: Grand Valley State University, Kalamazoo College, and
ArborText, Inc. In addition, Merit/MichNet has been picked to
provide network services for FALCON (the Flint Area Library
Cooperative Online Network).
Saginaw Valley State University will become a Merit member in
April, after having been an affiliate for some time. As part of
this change, we are now able to provide public dialin in the
Saginaw/Bay City area.
After extensive work on review and redesign, the MichNet News came
out the end of February with a new design and revised editorial
policy concentrating more on applications and accessibility for our
users.
In February, Merit/MichNet added a new feature to the Authorization
Server, its user authentication software. Previously, the
Authorization Server was used only to authenticate users who wanted
to telnet out of MichNet. In February, it began to handle charging
for a MichNet service that doesn't have its own charging
facilities. In March, the Authorization Server will also allow
collect calls from X.25 networks such as SprintNet and Autonet to
MichNet hosts that don't otherwise accept these calls; only three
MichNet hosts currently do have the ability to accept collect calls
from X.25 networks. This will give our users access to all MichNet
hosts from public dial-in throughout the U.S.

MITRE Corporation
-----------------
Walt Lazear participated in the organizational meeting of DCA's
PSTP working group on Network Management on 6 and 7 February.
Shari Galitzer, Forrest Palmer, Mike Saintcross, and Walt attended
demos of Trident Systems X-Touch products. The touch screen add on
for PCs and workstations are well integrated into X Windows and
offer excellent alternatives to mouse driven applications.
During the month, detailed briefings and demonstrations were
presented. Forrest presented SNMP to Government sponsors and MITRE
personnel. Shari presented BBN's MMConf to a similar audience.
Her demonstration included a NOC-to-NOC problem solving scenario
that integrated the various applications within MMConf. Walt

presented a CALS like documentation mockup using Framemaker as the
display interface.
Walt began talks with UUNET (the Alternet provider to MITRE) to
introduce OSI CLNP routing into their regional. Extending the OSI
protocols on the I.E. Testbed to the attached regional will allow
experiments to reach the rest of the Internet that has implemented
the OSI infrastructure. MITRE is also designing its internal OSI
structure for production usage of GOSIP applications as they become
available.

NEW ENGLAND ACADEMIC AND RESEARCH NETWORK
-----------------------------------------
NEARnet has grown to 67 members.
NEARnet's connection to the T-3 NSFNET backbone has been installed
at MIT and testing is currently underway.
Two new services were announced in February. Technical staff at
member sites are now provided with a guest account on nic.near.net
for remote diagnosis of network connectivity problems, and are
provided with access to a "mail reflector" for testing mailer
configurations.
In addition, NEARnet sent the first monthly issue of its online
bulletin of user information, "NEARnet This Month", in February.
NTM contains news and information about NEARnet, tips on using the
network, and a calendar of local and national events of interest.
To include an event, send your announcement to nearnet-
us@nic.near.net.
A document on how to connect Macintosh networks to NEARnet is
available in the public ftp directory, "docs", on nic.near.net,
under the filename "macintosh-options.ps".

network applications and resources, as well as a glossary of
networking terms. We've designed the Tour for the new network
user. We want it to be an easy and enjoyable way to learn about
the Internet. We would like to begin distribution of the Tour
sometime next month. If you have any questions or would like to
receive a copy of the Tour send your request to
<nnsc@nnsc.nsf.net>.
The NNSC distributed additions to Chapter 2 of the Internet
Resource Guide.
The NNSC published the 9th issue of the NSF Network News.
The NNSC continues to distribute many copies of both the Internet
Manager's Phonebook and the Internet Resource Guide. Both of these
publications are available online. For additional information

NSF BACKBONE (Merit)
-------------------
NSFNET BACKBONE PROJECT (Merit Network, Inc.)
During February 1991, the inbound packet count for the T1 NSFNET
backbone reached 6,029,601,114 packets. This is an increase of
2.76% over the January total of 5,867,911,410 packets. A total of
2417 networks are configured for announcement on the NSFNET
backbone as of the 28th of February.
The National Science Foundation announced an addition to Merit
Network, Inc.'s NSFNET cooperative agreement which will provide
expansion to T3 service for all of the current NSFNET T1 backbone
sites not initially scheduled for T3 access. These upgrades will
bring T3 service to all 16 sites. A deployment plan and schedule
are being developed for the eight additional nodes.
Work continues on provisioning T3 service. The T3 Ithaca node was
connected into the T3 infrastructure on 25 February. As part of an
ongoing review of T3 hardware and network monitoring tools, T3
Technologies and T3 PLUS demonstrated their equipment in Ann Arbor
at the Merit Network Operations Center. Representatives of the
Merit NOC, IBM and MCI met to discuss the continued growth and
evolution of customer service for T3 hardware and software.
FDDI interfaces have been deployed at NCSA, Urbana-Champaign; SDSC,
San Diego; and PSC, Pittsburgh. Traffic is being actively routed

Much of the work this month has been to do with setting up pilot IP
network services in London & the UK. The London project is based on
a fiber net used for Analogue Video, but with a 2 Mbps Data Network
overlayed - Livenet Data Network. The UK IP project is overlayed on
the current JANET backbone and is called `shoestring'.
The Advisory Committee to the JNT reported recently as follows:
"At the 1990 Networkshop the JNT invited members of the JANET
community to advise it on the response to the requirement within
the community for significantly improved interworking with
international Internet networks and for a national service to
support service using Internet Protocols (IP) across the wide-
area network.
...
The provision of IP represents a major change in strategy that
will have consequences in all aspects of networking in the JANET
community, now and in the future, and the DoDAG will continue to
study these during 1991. The OSI transition program is an area
of particular concern and the group will focus on this in
collaboration with other JNT advisory and management groups."
It should be stressed that this is a pilot. A Service will not be
in place until October.
One of the motivations for our involvement has been the wish to
extend Packet Video Conferenceing further into the UK.

1. The specification and implementation document for the Network
Time Protocol Version 3 has been updated with minor revisions
as the result of comments from the implementors. While this
document was submitted to the standards process some months
ago, there is no report on its progress. The new version
provides higher accuracy, reliable error bounds and requires
reduced network resources.

2. A preliminary report on our Highball high speed, wide-area
network has been completed. The design is based on a high
speed crossbar switch and an adaptive, distributed scheduling
algorithm. Progress to date in this project includes the
design and testing of a suite of scheduling algorithms,
construction of a software reservation/scheduling simulator
and design of a strawman hardware and software implementation.
3. Erik Perkins, Mike Davis and Dave Mills participated in a
DARTnet audioconference using a SPARCstation and ISI packet-
voice software, which worked wonderfully.

-------
All sites are now operational. Most of the members have completed
integration with the campus environment and are making service
available to end users. Two sites are not currently using their
connectons.
The user services committee completed work on model end user
documentation and it was distributed and made available over the
net. A series of meetings of user services and consulting staff
are planned for March.

FOX PROJECT
-----------
SRI
---
SRI hosted the third meeting of the IETF Directory Services (OSI-
DS) Working Group on February 12-13. 17 members attended this
productive meeting.
Because a majority of the FOX participants attended the OSI-DS
meeting, an informal FOX project meeting was held after its
conclusion. In attendance were Marshall Rose (PSI), Mark Knopper
(Merit), Chris Weider (Merit), Jose Garcia-Luna (SRI), Ruth Lang
(SRI).
The main topic discussed was how to offer WHOIS information via
X.500. Work has been done toward that end. PSI has populated
@o=Internet of the White Pages Pilot with FYI and RFC information.
Merit has populated @o=Internet with autonomous system and network
contact information.
In order to work with (rather than against) existing procedures and
policies for registration, and advertisement of this information
via WHOIS, it was decided that SRI would master a portion of the
DIT to maintain the WHOIS information (possibly,
@o=Internet@cn=WHOIS). SRI has begun work on identifying the
Internet related information that will be transitioned, and on
defining how that information will be represented in the Directory.
All were in agreement that the fundamental issue which needs to be
addressed is one of developing new methods of supporting
distributed registration and management of Internet information
among autonomous administrations.
