IETF Report:
Chair: Phill Gross/ NRI
1) I would like to welcome two new important members to the IETF
Steering Group (IESG). Steve Crocker of Trusted Information
Systems (TIS) will be the Director of the Security Area. His first
monthly report is below. Steve is involved, among other issues,
with developing a secure email system based on RFCs 1113-1115.
Russ Hobby (UC-Davis) has joined us more recently as the
Applications Area Director. Russ has already proposed some
specific application projects, and will make his first report next
month. This leaves only the Operations area unfilled. Until
filled, I will continue to serve as the interim Director. My
Operations Area report is below.
2) The next IETF meeting is at Florida State University at
Tallahasse on February 6-9, 1990. The local host is Ken Hayes.
The meeting is partly sponsored by the Department of Energy. The
agenda for the February IETF is quite full (see below). There will
be ~27 WGs meeting in ~37 sessions. There will be ~10 technical
presentations, and a report from all area directors.
3) There will be an open meeting of the IESG at the February IETF.
At the suggestion of Mike Karels at the last IETF meeting, we have
scheduled the IESG from 4-7pm on Thursday so it does not conflict
with other WG sessions or the technical presentations. The primary
topic of the IESG will be the issue of intra-AD routing protocol
(ie, IGP) standardization.

OSI INTEGRATION AREA:
Directors: Rob Hagens/UWisc, Ross Callon/ DEC
Reported by Rob Hagens/ UWisc
Several working groups of the OSI Area will meet at the February
IETF. The OSI General WG will discuss the status of RFC 1006 ("ISO
Transport Services on top of the TCP") as well as a proposed
companion document (currently an Internet Draft) "OSI
Connectionless Transport Services on top of the TCP".
A newly formed working group, OSI NSAP Guidelines (OSI NSAP), will
meet to discuss their task: a paper describing guidelines for the
administration of NSAP addresses.
The OSI X.400 WG will meet to discuss a scheme that will provide a
default X.400 OR Address for users that currently have a domain-
name-based 822 mail address.
NETWORK MANAGEMENT AREA:
Director: David Crocker/ DEC
Very active month.
SNMP, SMI, and MIB I are being considered for full Standard Status.
MIB II for Draft or Proposed status. An OSI-oriented SNMP-based
MIB is a candidate for Experimental status.
NOCTools has a draft document, in time for IETF.
AlertMan has a draft spec, in time for IETF.
OIM has a draft MIB-II spec, in time for IETF. There also are
rumors of CMOT product-oriented implementation interoperability
testing in the offing.

Internet Monthly Report December 1989
INTERNET SERVICES AREA:
Director: Noel Chiappa/ Consultant, Proteon
The main progress in this area this month was in the MTU Discovery
and Router Detection WG's, which held a joint meeting, and made
substantial progress towards picking final technical directions,
allowing RFC drafting to begin.
The consensus of the Router Discovery meeting was that a mechanism
very similar to the ES-IS mechanism for hosts to discover routers,
but based in ICMP, was what was desireable. Many other options,
including use of a similar UDP based service, RIP, proxy ARP, a
strict ES-IS subset, and a number of other new mechanisms, were
discussed and eventually put to one side. The mechanism would allow
both multi-cast and unicast requests, and routers would
periodically multi-cast replies as well; the replies contain a
"holding time" field. The latter features are intended to allow
this mechanism to be used as part of a future "black hole
detection" algorithm.
The consensus of the MTU discovery meeting was that a cross between
the "Report Fragmentation" (where the end host reports when it sees
incoming fragments) and "Probe Path" (where the routers along the
way indicate the max() of the MTU's of all the links) approaches.
The mixed apprach was preferred because in a situation involving
incremental deployment, you can guarantee neither that the end host
has been upgraded (as required by the RF approach), nor that all
the routers in the path have been (as required by the PP approach).
The mechanism is an IP option which is included occasionally in
packets. "This hybrid approach seems ... to combine the best of
both methods: it gives accurate, early results (i.e., before a
connection has to start sending big datagrams) without incurring
fragmentation if the routers cooperate, it detects fragmentation if
the receiver cooperates, and it causes conservative behavior
otherwise."
Several more new groups are in the process of being formed, and
will be announced shortly. Chairpersons have been selected for the
"IP over SMDS" and "IP Multi-media" WG's (the latter is looking at
issues relating to connection of dissimilar networks below the
router layer, such as by multi-media bridges), and the charters for
those groups should be out shortly.
In addition, it is hoped to form WG's to consider issuing a
detailed specification for use of variable width subnet masks, and
to prepare a complete enumeration of standards for transmission of
different protocols on all common media; in places where formal
Westine [Page 8]
Internet Monthly Report December 1989
standards are not written down, it will create such standards, in
cooperation with the appropriate standards bodies where possible.
SECURITY AREA:
Director: Steve Crocker/ TIS
A formative period for this area. Jeff Schiller is running the
sole working group and is focussed on IP authentication and SNMP
authentication. Two documents on SNMP authentication are being
reviewed internally and should emerge for wider review shortly.
More information on IP authentication later.
Rich Pethia, the leader of the CERT (Computer Emergency Response
Team) at the SEI (Software Engineering Institute) has agreed to
form a new working group in this area. There exact charter is
under discussion. Issues of interest range from defining a
security policy for the Internet to specific protocol developments
for trusted distribution and/or audit of software. These topics
and others will be discussed in the forthcoming draft five year
plan and shared with the IESG for inputs.
OPERATIONS AREA:
Interim Director: Phill Gross/ NRI
We are beginning to look at ways that the JOMAAN WG can better
serve the needs of both IETF and the Regional networks. We are in
the process of talking to FARNET on this and other ways of better
cooperation.
Craig Partridge is starting a new WG to help end users report and
track down network problems. This has both a User Services and an
Operations flavor, and demonstrates a new IESG emphasis on the
issues of operational stability.
There has long been regular status reporting of the major agency
backbones at the IETF plenary technical sessions. We are now
trying to better organize and coordinate these and other
operational reports. We are planning an ad hoc meeting at the Feb
IETF to look at common formats and common information for each
agency report. One of the goals will be to identify the key
information to represent network performance and status, and agree
on similar presentations of this information. The fullness of the
Feb IETF agenda has forced this to be an evening meeting.

TERRESTRIAL WIDEBAND NETWORK
During December, the Terrestrial Wideband supported 6 video
teleconferences. This included two RIG discussions led by Ira
Richer and Bob Braden. The second meeting was the first official
four-site conference including BBN, DARPA, SRI and ISI. The
Internet Engineering Steering Group also met this month.
ST/IP GATEWAY
Work continued on the ST gateway software and Terrestrial Wideband
infrastructure needed to support large scale distributed wargaming
(SIMNET). The initial version of the SIMNET ST host was completed
this month. This host successfully collected traffic from 600
simulated vehicles at one SIMNET site and delivered it to another
site. These sites were connected by two ST gateways and three
Terrestrial Wideband Packet Switches in a lab environment. These
were set up to simulate the delay which would exist in a real
network. Packet integrity and low delay were verified by wargame
simulators at the second site which integrated this traffic with
other local wargame exercise traffic.
EURO-DRI INFRASTRUCTURE
Upgrades were installed in the Butterfly Gateways at UCL, RSRE
(U.K.), and CNUCE (Italy) which included processors, new
interfaces, fast load board, and new software and configurations.
With the fast load boards, each machine now can be rebooted in less
than 3 minutes. New terminals were also installed, and people at
the sites discussed operations and theory of gateway use.
Gateway operations at SHAPE Technical Centre are being worked out,
so that the site can support the level of service that is needed,
both for themselves, and for other sites which may eventually
connect through them.
Westine [Page 10]
Internet Monthly Report December 1989
TCP/ISO TRANSLATION
Outlines for work with protocol translation between TP4 and TCP
with J.Wilkes at SHAPE Technical Centre have been discussed. Plans
are to compare different types of translation at the transport
layer, first the transport bridging services available in ISODE,
and then completing an implemention which translates individual
PDU's at the transport level, between the underlying network
service interfaces.
INTERNET RESEARCH
We distributed copies of the draft document "Inter-Domain Policy
Routing" to members of the Open Routing Working Group and are
presently awaiting comments. Once the revisions suggested by the
comments have been incorporated, we will release the document as an
Internet Draft. This we expect to occur by the end of January. A
meeting is scheduled at the February IETF to allow this document to
be openly presented and discussed.
In the draft, we present an architecture for policy routing among
administrative domains within the Internet. The objective of
inter-domain policy routing is to synthesize and maintain routes
between source and destination administrative domains (ADs),
providing user traffic with the requested service within the
constraints stipulated by the administrative domains transited.
Each administrative domain autonomously defines policy requirements
for traffic generated within it and sets and enforces policy
restrictions on traffic passing through it. We emphasize that
policy includes service access, quality, and charge.
The proposed routing architecture comprises the following
functions: collection, distribution, and maintenance of topology-
and policy-related information for routing; synthesis and selection
of routes requested by the source ADs; installation, verification,
maintenance, and repair of routes across the Internet; and packet
forwarding from one AD to the next. The architecture is designed
to accommodate an Internet with tens of thousands of administrative
domains collectively containing hundreds of thousands of local
networks.
The draft also contains suggestions for protocols to support the
functionality of inter-domain policy routing. We are presently
pursuing the detailed specification of these protocols.

CICNET
-------
CICNet has been active in a variety of areas during the past month.
These include the addition of three new Computer/Telecommunications
members, two new Universities, the further progress of our Video
Applications Study Group, and the funding of a PC/Fax hybrid
project for library applications. In addition, our network
traffic, in terms of packets transported, increased 112% from May
to November.
Effective at the December meeting of the CICNet Board of Directors,
Ameritech, Consolidated Network Inc., and MCI have become corporate
members of CICNet. This entitles them to participate in the
various applications oriented affinity groups established by CICNet
as members rather than as vendors. They are also entitled to
network connectivity consistent with acceptable use policies. In
addition, Purdue University and Indiana State University were
approved as Category II, Other University/Nonprofit Members of
CICNet.
CICNet's Video Study Group met on November 9, 1989 in Ann Arbor to
evaluate the various types of video applications and solutions that
might be appropriate over our network. Participants include end
users, networking groups, and vendors. Presentations were made by
members of the group and covered actual applications, video
technologies, and video networking issues. The study Group split
into two task forces: applications and technology. By the end of
January, the Applications group will arrive at two to three solidly
defined uses for video-based services. Concurrently, the
technology task force will be gathering information on all
available solutions, and be prepared to match those with the
selected applications. Once accomplished, CICNet plans to proceed
with tests.
At our October Library Director's meeting, a group from The Ohio
State University, led by Bob Dixon, successfully demonstrated the
use of a Group III Fax, PC with Fax card, and custom-designed
software to transmit and receive facsimile messages over the
Internet. CICNet is assisting in the deployment of the project,
both as a testbed and through modest levels of funding.
Westine [Page 12]
Internet Monthly Report December 1989
During November, 1989, CICNet carried 550 million packets, and
averaged over 18 million packets per day. CICNet also measures the
degree to which individual backbone network segments become
saturated during discrete 15 minute "busy periods". During May,
the greatest degree of concentration measured was 7%. During
November, it exceeded 30% on several network segments. A
measurement of 40% or greater indicates potential network
congestion. CICNet has created a standing Network Planning
Subcommittee to monitor and address these potential concerns.

INTERNET CONCEPTS PROJECT
Bob Braden began plans for the DRI open gateway testbed. He
organized two teleconferences to gather information about candidate
hardware/software platforms for the open gateways. This issue is
close to resolution.
Bob Braden also worked on a new version of statspy that
incorporates a major revision to the internal compilation
algorithms, to improve performance and to support the entire
extended language described in the SIGCOMM 88 paper. The new
version is expected to be released as version 2.5 early in 1990.
An ISI technical report on statspy internal design was also
completed; this is an expansion and revision of the SIGCOMM paper.
It includes a much more complete discussion of compilation
algorithms and a brief overview of the program internals.
Finally, Braden did preparatory work for the IAB meeting to be held
the first week of January 1990.
Jon Postel and Danny Cohen hosted the System Engineering for
Testbed SEFT meeting at ISI, Dec. 1, 1989. Discussions of this
meeting pertained to the engineering of DRI testbed networks. Jon
Postel hosted the CORNETT meeting at ISI Dec 13, 1989, to discuss
this testbed network. Greg Finn gave a lecture at USC campus on
Dec 13 on "IP Source Quench Congestion Control Algorithm."

MULTIMEDIA CONFERENCING PROJECT
The first official four-site teleconference was held this month
after earthquake repairs at the SRI site were completed.
The control protocol used by MMCC, the multimedia conference
control program, was enhanced this month to combat pathological
behavior caused by network partitioning. Additional timeouts were
put in place to avoid getting stuck waiting for another site to
respond. Mechanisms now exist for detecting state inconsistencies
and restoring state information when sites reconnect after a
partition.
We continued our investigation of the sound I/O facilities on the
NeXT machine. Although we have made some progress in understanding
the low level sound-driver interface, we have not yet been
successful in playing back sound recorded from the microphone, in
real time.

FAST PARTS
Alan Katz continued work on the mail-based FAX server. We can now
send FAXes manually from any workstation at ISI. The mail
interface to FAX is almost done. The FAST project has started to
use the server for price quotes and ordering on a restricted test
basis.

The system uses a Complete FAX 4800 baud FAX card in an IBM PC
which talks to a Sun workstation via RS232. The FAX card plus PC
acts as a FAX modem to the Sun. The software is written in GNU
Emacs LISP.

The T1 line between MRNet and the NSFnet backbone at UIUC is now
operational. Jeff Wabik coordinated the transition to the new line with
UIUC and MRNet members. The old 56k bps line to UIUC has been cancelled.
This line was funded by the Army High Performance Computing Research Center
(AHPCRC) contract. I expect substantial increased usage as the AHPCRC gets
under way. The Army Supercomputer Network (ASnet), the network which
connects the AHPCRC to Army sites, should be connected to MRNet during the
next month.

NORTHWESTNET
------------
As of January 2, 1990 NorthWestNet technical management has moved
from Boeing Computer Services (BCS) to the NorthWestNet member
institutions. The University of Washington has taken over the
responsibility for all NorthWestNet network operation center
functions. These functions include physical communications circuit
monitoring, problem identification, verification of problem
resolution, performance monitoring and reporting, and domain name
services. NorthWestNet trouble reports should be made to the
University of Washington at (206)543-5128.

NSF BACKBONE (Merit)
-------------------
Due to the December holiday period traffic on the backbone dropped
slightly from November. The total packet count for December was
2,087,081,146 which is 11.6 million less then November 1989. Daily
traffic was lower beginning on December 23 through the end of the
year.
Total network announcements through December 31 stand at 927
compared to 897 at the end of November.
SYNCHRONIZING THE CLOCKS
As we moved into the new decade a "leap second" was added to
official clocks around the world. The NSFNET adjustment was
automatically handled by a new implementation of the Network Time
Protocol, configured and installed on the RTs at all nodes on the
backbone by Dave Katz. The new implementation was written by
Dennis Ferguson of the University of Toronto.

MERIT/NSFNET STAFF ACTIVITIES DURING DECEMBER
Elise Gerich was an invited speaker at a ComForum event sponsored
by the National Engineering Consortium: "Broadband: Services,
Technology and the Future." Elise spoke about the architecture of
NSFNET and the future of the network as a national data
superhighway.
Dave Katz hosted a working group to develop an Internet standard
for the use of the OSI IS-IS (IS = Intermediate System) routing
protocol in IP-only and dual (OSI and IP) environments.
RFC 1136, "Administrative Domains and Routing Domains - A Model for
Routing in the Internet" by Susan Hares and Dave Katz has been
published. This document proposes a model for describing routing
within the Internet, based on the OSI Routing [sic] Framework (ISO
TR 9575).

During December, we moved all systems (hosts, routers, printers,
etc.,) to our Class B Address (132.249). Our Class C Address
(192.12.207) will be retained for experimental use. With this
change we have finally subnetted our building using the NSC EN641's
multiple Ethernet ports as the hub. A cisco AGS is serving as
backup. The move was accomplished during two days (18 & 28
December) with the normal cleanup following each session. During
the second session, we uncovered several "glitches" with name
servers, old host tables, etc.
We have established SNMP sessions to our major hosts which support
the protocol, all routers, etc. As such items as our Fastpaths are
upgraded, they too will be monitored by SNMP.
by Paul Love (loveep@sds.sdsc.edu)
Since our last report:
Both our Proteon p4200 and cisco AGS have been updated to the
latest rev levels.
We continue to have linemode problems with Telnet under UNICOS -
usually caused by non-cooperating clients.
Our old PSN (26) finally did get removed.
The latest version of Multinet has been installed. With it, our
VMS systems can be watched by SNMP.

In December, 26 new connected IP network numbers are assigned. In
addition, 61 unconnected IP numbers are assigned this month. The
total number of all assigned IP numbers is now 3,740 which includes
2,125 connected networks and 1,615 unconnected networks. The total
number of Assigned Autonomous System numbers (ASNs) is 560.
There are currently a total of 1,277 registered domains which
includes 45 at the top level, 1,191 at the second level, and 41

algorithms for gigabit networks. Mike Davis continued work on
NSFNET traffic-monitoring data. Erik Perkins continued review
and preparation for RIG-related experiments. Ken Monington
continued work toward a Master's thesis on clock-
synchronization algorithms. Dave Mills attended a DARPA
telemeeting on RIG-related experiments.
2. Edited proceedings of the INARC Workshop on the Future of the
Internet System Architecture and TCP/IP Protocols, held at U
Delaware last June, are to appear in the next issue of the ACM
Computer Communication Review.

3. Improved algorithms for use in the Network Time Protocol have
been implemented and are now operating in all fuzzball primary
and secondary time servers. The new design improves
timekeeping accuracy and frequency stability by about a factor
of ten, while reducing network overhead by a factor of 16.
The overall performance of the NTP system is reported in a
paper to appear in the next issue of the ACM Computer
Communication Review.
4. The kind folk at the US Naval Observatory calibrated our
exotic cesium clock to within the microsecond. Modifications
to the fuzzball now provide precise seconds synchronization to
the cesium clock with seconds ambiguity resolved by radio or
NTP. All time servers, radios and oscillators within reach of
campus nets are now verifiably synchronized to within a
millisecond of UTC. We are monitoring the system using a
LORAN-C receiver calibrated with the aid of precision
geographic coordinates. The scheme demonstrates the
practicality of unambiguous, precision synchronization in
areas of the world where radio services are unavailable.
5. The Great Leap of '89, being a saga of the transient response
of the Internet time servers to the insertion of a leap second
in the international time scale, was something less than a
complete success. Carefully prepared plans to avoid
disruption due to confused radio clocks and misleaped servers
didn't work in all cases and led to bizarre behavior something
like a pinball machine. We all learned much from this, but
won't get a chance to test it for another 18 months or so.

INTERNET CONCEPTS PROJECT
Bob Braden began plans for the DRI open gateway testbed. He
organized two teleconferences to gather information about candidate
hardware/software platforms for the open gateways. This issue is
close to resolution.
Bob Braden also worked on a new version of statspy that
incorporates a major revision to the internal compilation
algorithms, to improve performance and to support the entire
extended language described in the SIGCOMM 88 paper. The new
version is expected to be released as version 2.5 early in 1990.
An ISI technical report on statspy internal design was also
completed; this is an expansion and revision of the SIGCOMM paper.
It includes a much more complete discussion of compilation
algorithms and a brief overview of the program internals.
Finally, Braden did preparatory work for the IAB meeting to be held
the first week of January 1990.
Jon Postel and Danny Cohen hosted the System Engineering for
Testbed SEFT meeting at ISI, Dec. 1, 1989. Discussions of this
meeting pertained to the engineering of DRI testbed networks. Jon
Postel hosted the CORNETT meeting at ISI Dec 13, 1989, to discuss
this testbed network. Greg Finn gave a lecture at USC campus on
Dec 13 on "IP Source Quench Congestion Control Algorithm."

MULTIMEDIA CONFERENCING PROJECT
The first official four-site teleconference was held this month
after earthquake repairs at the SRI site were completed.
The control protocol used by MMCC, the multimedia conference
control program, was enhanced this month to combat pathological
behavior caused by network partitioning. Additional timeouts were
put in place to avoid getting stuck waiting for another site to
respond. Mechanisms now exist for detecting state inconsistencies
and restoring state information when sites reconnect after a
partition.
We continued our investigation of the sound I/O facilities on the
NeXT machine. Although we have made some progress in understanding
the low level sound-driver interface, we have not yet been
successful in playing back sound recorded from the microphone, in
real time.

under way. The Army Supercomputer Network (ASnet), the network which
connects the AHPCRC to Army sites, should be connected to MRNet during the
