1. The Boston IETF meeting, held July 12-17, was "well attended"
in that there were over 680 meeting attendees. Special thanks
go to Chuck Davin and Jeff Schiller of MIT, and John Curran of
NEARnet for the amazing work they did hosting the meeting,
providing the terminal room, and for organizing the social event,
and to the Hyatt Regency Staff.

As was the case in San Diego, this IETF meeting enjoyed some
"firsts." This meeting broke the 600 attendee mark as there were
over 680 attendees.

Following up on their successful efforts in San Diego, Steve
Casner, Steve Deering, and a host of others joinged together
and provided both an audio AND video broadcast of the technical
presentations and open plenaries. There were 92 sites receiving
audio broadcasts, and 45 sites that also received the video
broadcast. The receivers of the audio/video broadcasts were
spread over 11 different countries!

INTERNET PROJECTS
-----------------

BOLT BERANEK AND NEWMAN INC.
----------------------------

INTER DOMAIN POLICY ROUTING

During the month of July, we have been assessing the set of
tasks to be completed for IDPR version 1. These include:

(1) Updating the MIB Internet Draft;
(2) Updating the configuration and usage document;
(3) Implementing the MIB;
(4) Getting the required changes officially placed in the DNS;
(5) Bringing the gated version of IDPR in line with the protocol
specification.

We are working on tasks (2) and (4). At the July IETF, other members
of the IDPR Working Group volunteered to work on tasks (1), (3), (4),
and (5).

We are still planning on an Internet pilot of IDPR for late summer or
early fall. Those interested in obtaining a copy of the IDPR gated
software, please contact Woody Woodburn (woody@sparta.com).

TWBNet

During July, we fielded a new WPS release (v11.3). Throughout the
month, the network has been stable and working well with this new
software. In addition to some bug fixes and some enhancements in
measurement and reporting of Butterfly clock speeds, the monitoring
and system, the following new features have been added:

1. RAM card support -- This provides support for:

+ Faster rebooting -- All of the WPSen in TWBNET will be, or
have already been, upgraded to have a Multibus card cage
and a 1.5MB battery-backed RAM card. This is enough
memory to store all of the WPS application software plus
the operating system Chrysalis plus several debugging tools
and symbol tables, and still have lots of space left. By
storing the software on the RAM card, the time needed to
reboot the WPS drops by 80% -- from about 35 minutes to
around 7 minutes.

+ Improved crash cause analysis -- When a WPS crashes, it will,
if possible, write out "what was on the console screen" to



Cooper [Page 10]

Internet Monthly Report July 1992


a file on the RAM card. (Each crash writes to a different
filename.) New monitoring and control commands have been
developed to permit these files to be uploaded to the NOC for
study, and to make it easy to selectively delete these files.

+ Retention of configuration and parameter information updates

In previous versions of the software, there was no convenient
way to save configuration or parameter changes and restore
them after a complete reboot. In v11.3, the RAM card is used
to save and restore configuration and parameter information,
eliminating the need for frequent WPS config file change and
distribution.

2. Large-WPS support

An aspect of recent WPS upgrades is that the WPSen are being
converted from 2-column Butterfly machines (which support 1-16
processors) to 4-column Butterfly machines (which can support
64 processors) to allow expansion in the number of gateways
that can be attached from 7 (today) to 20 or so. This
software release includes table size increases needed to
support the larger number of gateways and the larger number
of processor nodes.

3. Builtin (static) group address tables increased

Previous releases have supported only three builtin groups,
with at most 10 members each. Release 11.3 supports seven
builtin groups, with at most 30 members each.

A "builtin" or "static" group is a HAP multicast address
whose member list is constant (they're specified in the WPS
config file). Currently, builtin groups are used to support
the Conferencing and SIMNET applications where multicasting
of packets is valuable. The distinction between "builtin
groups" and "dynamic groups" (which will be in a future
release) is that dynamic group addresses are allocated and
freed using HAP Setup Request commands, and members join
and leave the group as they wish, whereas static groups map
specific HAP addresses into a fixed membership list.

4. Better stream and priority datagram service

Part of providing good service to stream and high-priority
datagram traffic is making sure that a high priority packet
gets sent reasonably quickly even if it arrives after a group
of lower priority packets. This means that, even when there's



Cooper [Page 11]

Internet Monthly Report July 1992


no high priority traffic to send at all, the device driver
output queues can't be allowed to fill up with too much lower
priority traffic.

In order to limit the maximum delay a late-arriving high
priority packet would suffer, line rate sensing has been
implemented in this release. The HAP interface measures
the rate at which data is being transmitted and then limits
the amount of data enqueued to keep the maximum delay below
a preset threshold. (The threshold is an adjustable parameter,
and is currently set for about 200 milliseconds.)

CERFNET
-------

During July CERFnet made some changes to the management staff.
Susie Arnold has elected to leave her full-time position with
CERFnet as manager of operations and enginnering to pursue a new
career in teaching. Susie will still be available over the network,
however, at her CERFnet mailing address which is listed below.
(once a network junkie, it's hard to stop!)

Pushpendra Mohta will be assuming responsibilities for engineering
and Dan Matzke will be the manager of NOC operations. Susan Calcari
remains as manager of network information services.

CSUNET (THE CALIFORNIA STATE UNIVERSITY NETWORK)
-----------------------------------------------

The California State University network (CSUnet) completed the
connection of two Mexican universities at 56K DDS: CETYS (Centro de
Ensenaza Technico Y Superior) and ITM (Instituto Tecnologico de
Mexicali). CETYS has three campuses which are being interconnected
(Tijuana, Mexicali, and Monterrey) for use by engineering students



Cooper [Page 12]

Internet Monthly Report July 1992


and faculty. ITM is involved in MEXnet, a Mexican association
formed in January, 1991.

"MEXnet is an association of higher education and research
institutions of Mexico. The meaning of MEXnet is Mexican
Telecommunications Network for Higher Education and Research
Institutions (Red Mexicana de Telecomunicaciones para
Instituciones Academicas y de Investigacion).

And getting in mind that this is the time where the
technology development depends on the Computer Networking
of each educating institution. MEXnet is looking for the
Data Bases, the BBS, the information stored in most of the
computers around the world must be in the hands of every
Mexican institution. ..."

Also, in July, CSUnet connected the first two of the ten LATA
connections to the Pacific*Bell Knowledge Network (the Pacific*Bell
K-14 Educational Networking Project).

These T-1 TCP/IP connections are in support of the cooperative
agreement between the Trustees of the California State University
and the Pacific*Bell Knowledge Network Project.

The first two connects are to the Hayward and Anaheim central
offices. At each CO, Pacific*Bell has a Cisco AGS+ router. Cisco
uses the CO's as hubs for the Knowledge Network. The Ciscos are
the center of a star topology that connects NAT (Network
Applications Tecnologies) routers to the Cisco network.
Pacific*Bell also uses Proteon routers internally.

Some concerns that have been addressed including responsible use of
the IP addressing space, naming issues for the K-14 community, and
fees by CSUnet's neighboring regional networks for advertisement of
the IP numbers to the NSFNET.

Pacific*Bell and CSUnet decided to use a Class B network
partitioned which a standard 8-bit subnet mask. This mask is
solely for the trial period. The idea being that each high school,
community college, etc, will be alloted a subnet of its own and if
need be, additional subnets. Pacific*Bell expects to change to a
larger subnet mask to conserve addressing space. Since
Pacific*Bell provides this the TCP/IP service for a fee, efforts
continue for an attractive low-cost offering to K-14 users.

FARNET (FEDERATION OF AMERICAN RESEARCH NETWORKS)
-------------------------------------------------

(May, June and July 1992)

FARNET has three new members: Sprint (Full Member), Wiltel
(Associate Member), and MOREnet (Associate Member).

In May 1992 FARNET held a quarterly membership meeting at the
Microelectronics Center of North Carolina, hosted by CONCERT
Network. The theme of the meeting was "Business and Strategic
Planning for Your Organization". Attendees learned a set of
techniques for evaluating the "stage" of maturity which a business
or industry has reached and a set of questions for planning the
future of your organization.

In June several FARNET members attended the INET92 conference in
Kobe, Japan. Presenting papers or chairing sessions at the meeting
were: Elise Gerich, MERIT (Internet connectivity issues); Phill
Gross, ANS (routing and adddressing working group presentation);
Sergio Heker, JvNCnet (a practical approach to network connectivity
problems); Martyne Hallgren, Cornell (dynamics of electronic
collaboration); Richard Mandelbaum, NYSERNet (chair of panel on the
future of the Internet); Laura Breeden, FARNET (chair of North
American regional session); Glenn Ricart, SURAnet (North American
regional session); Al Weis, ANS (commercial networks as related to
research and education networks). More than 550 people
representing 70 countries attended the conference.

In July FARNET sponsored a workshop with NSF support to analyze and
provide commentary on the Draft NSF Solicitation for the Routing
Authority/NAP Manager and vBNS Provider. Results of this workshop
are available via ftp from host farnet.org, in directory
farnet_docs, filenames iinren*. Key recommendations included: NSF
should reaffirm its historical commitment to providing broad
support for research and educational networking; transition
planning should be carried out well in advance of any changes and
should include representatives of the provider community; and the
functions of the NAP Manager and Routing Authority should be
decoupled.

Also in July FARNET hosted a workshop for regional laboratory
directors from the US Department of Education's Office of
Educational Research and Improvement (OERI) and FARNET members.
This event brought representatives from nine of the 10 regional
labs together with FARNET member representatives from across the
country, and included staff from the National Science Foundation
(DNCRI and Education and Human Resources/Application of Advanced



Cooper [Page 14]

Internet Monthly Report July 1992


Technology divisions) and the Department of Education (OERI). The
foundation was laid for productive partnerships at the state and
regional level between the two sets of regional organizations.

Susan Calcari of CERFnet represented FARNET at the ESNET Steering
Committee meeting in Santa Fe, NM on July 15-16, where she made a
presentation about Internet user services and their evolution.
Thanks, Susan!

FARNET hosted a BOF at the Cambridge IETF meeting to report on
preliminary results of its meeting to discuss the NSF Draft
Solicitation.

In August, FARNET's regular quarterly meeting will focus on new
technologies, with talks by a range of vendors on topics from
network management software to routing technologies.

GIGABIT NETWORKING

ATOMIC

The ATOMIC project at USC/ISI installed its first Mosaic-based 3-
by-3 mesh router board, measuring approximately 8 inches by 9
inches. This router may be configured as either a 6-by-6 perfect
crossbar or a 12-by-12 blocking crossbar.

Six ATOMIC LAN host interfaces were attached to that router. That
configuration achieved a combined throughput of 1.3 Gb/s across the
router, a figure approximately 1/3 of the expected 4 Gb/s capacity.
We are unable to generate more than 1.3 Gb/s of host packet traffic
currently and so cannot test this small-scale router to saturation.

The full-scale ATOMIC router is a same-size board configured as a
16-by-16 perfect crossbar or 32-by-32 blocking crossbar. Samples
exist. These are undergoing fabrication testing and as routers are
expected to achieve 10 Gb/s.

MULTIMEDIA CONFERENCING

At the July IETF in Boston, Internet teleconferencing continued to
break new ground! This time, both packet audio AND video were
"mediacast" to participants spanning 170 different hosts and 10
different countries (AU, CA, CH, FR, JP, NL, NO, SE, UK, US). The
configuration supported widescale listening and viewing of not only
the general sessions, but also working groups pertaining to
Audio/Video Transport, Teleconferencing Architecture, and IP
Multicast. The DARTnet served as the multicast backbone with
tunnels branching out over T3 backbone, lightly-loaded T1's and
Ethernets. We are now coordinating the construction of the MBONE,
the multicast backbone, to expose IP multicasting to scaling
problems of 1 to 2 orders of magnitude.




Cooper [Page 16]

Internet Monthly Report July 1992


In the AVT WG, Steve Casner presented and led discussion on the
second iteration of a strawman for a real-time transport protocol.
In the Telearch BOF, Eve Schooler gave a presentation about the
Control Control Protocol (CCP) for flexible n-way session
orchestration. The hope is that IETF efforts in these areas will
lead to broader solutions for telecollaboration across the
Internet.

Working with students at USC, we integrated software decoding of
the compressed video used in DARTnet experiments with packet
reception and X-window display software. This enables a larger
number of receivers to participate in DARTnet experiments without
additional hardware cost, and it facilitates workstation-based
personal conferencing by eliminating the need for a separate
monitor on which to display video.

The implementation of CCP underwent refinements and testing over
DARTnet this month.

NSFNET/ANSNET BACKBONE ENGINEERING
----------------------------------

T3 Backbone Status
==================

Traffic migration from the T1 to the T3 backbone is in its final
stages, with only a few networks on T1 left to be cut over to T3.
New software is being deployed on the T3 backbone nodes to further
improve performance and stability. Load-related problems continue
to occur on the T1 network's Routing Control Processors and are
being addressed with software changes to improve RCP efficiency.
Activities for the "Phase IV" upgrade of the T3 backbone are being
planned including FDDI adapter upgrades and other changes that will
support dismantling of the T1 backbone later this year.




Cooper [Page 21]

Internet Monthly Report July 1992


Traffic Migration and Statistics
================================

In July, 12,884,937,091 packets entered the T3 network, up 20% from
June. 4,754,950,521 packets entered the T1 network, down 17.5%
from June. The total for both networks (minus cross-network
traffic) was 17,063,064,412, up 8.4% from June.

6130 networks are configured for the T1 backbone, and 5269 for the
T3 backbone. Actual network announcements by mid-level peer routers
to the T1 backbone are 4426 networks, and 3508 to the T3. It is
interesting to note that 1246 of the configured T1 networks were
never actually announced to the backbone during the month; and 882
of the configured T3 networks were never announced to the backbone.
New software has been installed to track the number of announced
networks over time.

During July, NorthWestNet, Terrestrial Wideband (TWB) Net, Milnet
and Minnesota Supercomputer Center (MSC) Net were cut over to the
T3 backbone. The remainder of the networks for Sprint and
International Connections Manager (ICM) were cut over in early
August.

Networks remaining to be cut over are: ESNet, Mexican Networks (at
Boulder), EASINet, and CA*Net. The first two are expected in mid-
August. The EASINet and CA*Net peers are currently only physically
connected to the T1 backbone and will be moved to allow peering
with the T3 backbone in early September.

Improvements to the T3 Backbone
===============================

New Software Build
==================

Version 2.81.31 of the AIX software and microcode has recently been
deployed on the T3 backbone nodes. This build includes several
significant fixes to problems and improvements to performance.
These include: a buffering change to increase performance for T3 to
ethernet interface transfers, a fix to a condition that causes an
ethernet interface to freeze, on-card support for additional
ethernet MIB-II variables, changes to the T3 card microcode, and a
fix to a bug in ICMP time-stamp processing (now resolves to the
millisecond).







Cooper [Page 22]

Internet Monthly Report July 1992


T3 Routing Software Changes
===========================

Numerous improvements have been made to the T3 routing daemon,
rcp_routed. These are described in release notes available for
anonymous ftp:

ftp.ans.net:/pub/info/t3-rcp_routed/Release-Notes

The most significant recent change provides a workaround for
regionals that generate a default pointing at 140.222 and find
their ENSS isolated from the rest of 140.222 T3 system due to loss
of the ENSS link to the CNSS. Other changes include better
handling of BGP external metrics, and various reliability and
operational improvements.

Routing stability measurements have been made over the last few
months. This information, in addition to the detailed logs have
helped identify routing disturbances, isolate problems involving
connectivity loss (IS-IS adjacency loss or BGP disconnect) which
should not have occurred, and correct the problems. This has
resulted in a measurable improvement in BGP stability.

FDDI Interface Upgrade Planned for August
=========================================

We are planning to upgrade the existing FDDI interfaces deployed on
several ENSS nodes to new RS960 technology based interface
adapters. Due to the complexity of the May '92 T3 upgrade, and the
need for operational stability, it was decided not to upgrade the
older FDDI interfaces at the same time as the T3 network. Instead,
it was decided to decouple the process of testing and deployment of
the new T3 technology from the new FDDI technology. The FDDI
interface that is installed at each T3 ENSS location will be
upgraded from an earlier technology to the newer RS960 adapter
technology in August '92. This will raise the peak throughput
observed by end users well beyond the current 10-14Mbps that may be
observed today. Our objective is to continue to incrementally
improve performance while maintaining very high reliability.

Once the new FDDI adapters are installed and operational at the
existing nodes, we will explore installations at other ENSS nodes
that do not yet support FDDI.








Cooper [Page 23]

Internet Monthly Report July 1992


New SNMP Daemon Installed
=========================

A new release of the SNMP software on the T3 backbone was
installed. With the deployment of build 2.81.31 and SNMP version
3.213, in and out octet counts are available for the T960 ethernet
and T1 cards. The current MIB variable map for the ethernet, T1
and T3 interfaces supported by the RS6000 nodes is as follows.

inU outU inNU outNU inOct outOct InErr OutErr
====================================================================
T960 Ethernet | U+B U+B 0 0 OK OK IN+OUT 0 |
RS960 T3 | 0 0 IN OUT OK OK OK OK |
====================================================================

The pending operating system upgrade of the RS/6000 routers to AIX
3.2 will allow for more complete support of the appropriate MIBS
for each adapter type.

RS/960 Memory Parity Problem
============================

A manufacturing problem with memory chips on a small number of the
RS960 T3 interface adapters has been identified and corrected.
However to protect against recurrence or new introduction of memory
problems, we are scheduling diagnostics to be run on some nodes
along with other scheduled maintenance over the next few weeks.

DSU Synchronization Problem
===========================

A problem was observed in the first few weeks after the April-May
deployment of RS/960 T3 cards and DSUs, where a T3 DSU would lose
synchronization with its peer on nodes that connect to the Houston
POP. This problem has not been reproducible in our test labs or in
the T3 Research Network after extensive experimentation, nor has it
occurred on production nodes since then.

DSU PROM Upgrade
================

The firmware in the T3 Technologies DSUs will be upgraded to a new
level, allowing extended remote monitoring capability. This
upgrade will be performed in the late August timeframe with plenty
of advanced notice.






Cooper [Page 24]

Internet Monthly Report July 1992


T1 ENSS Memory Upgrades
=======================

Each of the T1 ENSS nodes on the T3 backbone were recently upgraded
from 16MB -> 32MB of main memory to provide capacity for increased
paging.

T1 Backbone Status
==================

A new rcp_routed release was deployed early in July which increased
the BGP packet size to 4096. This was necessary to allow a full
complement of networks to be announced from the backbone to
regional peers (the same change was made to the T3 rcp_routed).

Later in the month another new rcp_routed version was deployed
which contained changes to support compression of the IS-IS
protocol LSP. This is necessary to allow the T1 network to sustain
the current limit of 2200 networks being announced in from external
mid-level peers to a single NSS.

NSS 11 at Houston exhibited some problems after the Milnet networks
were cut over to the T3 backbone. Some mid-level peers announce
all of the networks learned from the T3 backbone into the T1
backbone, and these are stored by the T1 node but are marked as
unusable. This caused the Houston RCP to run out of memory. A
change was made to the peer routers to prevent these networks from
being announced to the T1 network, and a future release of the
rcp_routed will include a change so that these routes are not
stored.

T3 Backbone Phase IV Planning
=============================

Upgrades to the T3 backbone are being planned to support future
performance and functional enhancements, and to allow the
dismantling of the T1 backbone. The major features of this plan
include:

1) T3 ENSS FDDI interface upgrades to new RS/960 card.

2) A T1 circuit will be installed at each T3 ENSS to allow
a backup connection to a different CNSS. This will provide
some redundancy in the case of T3 circuit or primary CNSS
failure.

3) Network source/destination pair traffic statistics collection for
the T3 nodes. This feature is provided on the T1 backbone



Cooper [Page 25]

Internet Monthly Report July 1992


currently.

4) Open Systems Interconnection/Connectionless Network Protocol
(OSI/CLNP) support. This feature is provided on the T1 backbone
currently.

5) Upgrade selected T3 ENSS ethernet interfaces to new RS/960
ethernet card.

6) Topology Changes:

o Moving the Washington D.C. area CNSS to a new MCI POP for
closer proximity to several ENSS locations. The tail
circuits of the existing network attachments to this
POP will be reduced to local access circuits only.

o Deploy a new CNSS in Atlanta to reduce the GA Tech T3 tail
to local access only, and provide expansion capability in
the southeast.

NSFNET/INFORMATION SERVICES
---------------------------

The total number of networks announced to the NSFNET
infrastructures reached 6031 at the close of July, with 4950 of
these nets also announced to the T3 backbone. Estonia and Thailand
are the newest foreign locations with networks announced to the
NSFNET; 2133 networks of the total represent foreign network
announcements.

Merit announced WAIS and Gopher servers in July for the
nic.merit.edu information server. This server has archives on the
Internet, NSFNET, and MichNet. Currently, there are six Merit WAIS
databases with more planned for the near future:

nsfnet-rfcs.src The Internet Request for Comments and
Internet Draft documents.

internet-standards.src The sub-series of RFCs which
document Internet Standards.

internet-intros.src Introductory material on the Internet.

PITTSBURGH SUPERCOMPUTER CENTER
-------------------------------

Jamshid Mahdavi and Jon Boone helped the PSC join in the recent
audio and video multicast of the plenary sessions of the IETF. We
ran BBN's dvc for video and Van Jacobson's vat on a Sparcstation
1+. Besides viewing the multicast ourselves, we performed a local
redistribution of the multicast. About 20 PSC staff members
followed along with some of the sessions.

Gene Hastings, Matt Mathis and Wendy Huntoon of the PSC attended
the IETF conference. Gene chaired the Network Joint Management and
Network Status Reports working groups. Matt chaired the BGP
(Border Gateway Protocol) Deployment working group, which is
fostering BGP in the Internet. The current global BGP topology was
presented, including a description of the European "EBONE" which
uses BGP as its interior routing protocol. Many router vendors
described their BGP plans. There is a strong consensus that BGP is
needed as soon as the vendors can support it. ANS publicly offered
to help vendors with interoperability testing, this will be a big
push for BGP.

SDSC (SAN DIEGO SUPERCOMPUTER CENTER)
-------------------------------------

SDSC Network Activities
=======================

In support of the joint SDSC/ScrippsClinic/UCSD Med School
SigGraph92 Showcase (an electron microscope at UCSD was controlled
from the Showcase) we established a FDDI link to Scripps Clinic
using loaned NSC equipment. This will be the beginning of the MAN
ring linking sites here on the mesa.

We also ran some end to end test between SDSC and ANL (as a stand-
in for the SigGraph show floor) which showed disappointing
performance. After some follow-up tests are run this month, we
will post our results.

We have taken our UltraNet hub out of service and are in the
process of removing the various interface cards. As a replacement,
we plan to use FDDI in the short term. Our permanent solution will
be the NSC HiPPI P32 switch.

For the CASA gigabit testbed project, we have ordered a HiPPI
attached frame buffer and a HiPPI attached Sun workstation to run
the HILDA network analysis system. We have also placed an order for
a HiPPI link level tester to help maintain our fast growing HiPPI
LAN.

SDSC Applied Network Research Group
===================================

The ANR group at SDSC has completed two papers in network analysis,
and is currently in the middle of projects which will lead to
several others.

The first paper is a description of recent traffic characteristics
of the T1 NSFNET backbone. We present this paper as a followup to



Cooper [Page 29]

Internet Monthly Report July 1992


the 1973 landmark paper by Kleinrock on ARPANET measurement and
analysis. We include a description of the NSFNET environment,
including available instrumentation and operationally available
data sets. The measured quantities include: longterm growth in
traffic volume, including attribution to domains and protocols;
trend in average packet size on the network, both over long and
medium term intervals; most popular sources, destinations, and site
pairs; source-centric favoritism; international distribution of
traffic; mean utilization statistics, both of the overall backbone
as well as of specific links of interest; delay statstics; and,
assessment of downtime for the last few years.

The second paper is an exposition on measurement considerations for
assessing unidirectional latencies. We actively evaluated single
direction latencies to selected destinations of the Internet
utilizing a variety of paths. Our objective was to demonstrate
that round-trip latencies are an insufficient and sometimes
misleading method to determine unidirectional delays. This claim
has significant implications for today's high-speed, multi-
application networking environments which often require
predictability of precise delay. For example, designers of real-
time applications who intend to deploy their products on the
Internet, or some wide-area, high-speed, highly aggregated network,
should be aware that across the periphery of such an environment,
symmetric delay will serve unpredictably as a model of network
performance.

Another ANR project underway is an investigation of the delay,
throughput and reliability characteristics of [transport layer]
connections. This project will include a routing dynamics component
to account for system routing dynamics. We have designed
experiments to measure delay, delay variance, reliability and
connection throughput for a variety of end-to-end configurations.
An end goal is to mathematically parametrize these quantities in
terms of some base network quantities, such as: number of ASs
traversed; size (hops, delay, etc.) of transit AS; min, max,
average data switching speeds; or average routing instabilities.
The project objective is a better response to the questions: How
does the Internet perform? Can we predict its performance based on
path information?

ANR is pursuing ongoing investigation into the visualization of
network phenomenon and characteristics. Initially, we would like
to focus on geographic representation of traffic flow between
countries, for example the animation of selected frames to produce
a visual time series of this data.





Cooper [Page 30]

Internet Monthly Report July 1992


Finally, we continue to exploring traffic sampling techniques and
their effect on the characterization of wide-area high speed
traffic. The project objective is to investigate the effect of
sampling on our ability to answer selected questions about traffic
characteristics on high speed networks. We are motivated by the
increasing difficulty in fully monitoring high-speed wide area
network environments.

We therefore intend to investigate a variety of sampling parameters
and frequencies, and compare the answers to various questions:
packet type distribution, geographical distribution of traffic. We
would like to assess confidence intervals for the resulting values.
Eventually, we hope the project enables us to construct an optimal,
stochastic sampling technique which responds to dynamic
characteristics of the environment.

1. Thanks to Louie Mamakos a version of the Network Time Protocol
Version 3 (NTPv3) supporting the RSA Message Digest 5

2. Thanks to the kindness of Digital Equipment, we now have a

timekeeping experiments. These are to be equipped with FDDI
interfaces and flashy clock-interface boards capable of
submicrosecond resolution.

3. The document "Simple Network Time Protocol (SNTP)" has been

4. NTPv3 has been deployed in DARTnet and several overseas
networks, besides many sites in the U.S. and Canada. It is
hoped that widespread replacement of earlier versions can
reduce the overheads at presently overloaded servers such as
umd1.umd.edu, which now suffers some 70 packets per second,
many times what was once thought a redline condition.

work is being carried out at Merit, NSYERNet/PSI, SRI and ISI. ISI
is the main contractor and responsible for project oversight.

ISI
---

ISI is working on an RFC to be called "User's Guide to Portable
DUAs." This document explains how users with an absolute minimal
familiarity with X.500 and ISODE can easily set up DUAs in their
own environments. The DUAs require only small portions of the
ISODE environment to be present, sparing the user the hassle of
dealing with ISODE's voluminous directory tree. This document

gives simple setup procedures for four DUAs: "WHOIS", "de",
"doog" and "ud". The document anticipates setup procedures for
other DUAs as future additions.

NIST/GSA X.500 Pilot
--------------------

Dialup access to a Directory user interface is now available, for
those agencies not in possession of Directory User Agent (DUA)
software. Users may log in to an account on the pilot DSA host
system via modem. The guest account will automatically run a
Widget user interface and connect into the pilot DSA.

Custos (the NIST X.500 Implementation)
--------------------------------------

July saw the completion of a statistics package which enables us to
glean usage information for the pilot, based on the operational log
record produced by the DSA. Information collected includes: the
number of DSA restarts (an indication of how many times the DSA was
shut down or crashed each month); the number of incoming
connections handled, both over the DAP, DSP and in total, which
gives an indication of frequency of use; the number of Directory
operations processed, an indicator of intensity of use; and a
breakdown by operation of the kinds of operations performed, which
gives an indication of the most common types of usage (such
information will be useful in determining how to optimize a
particular DSA configuration). Statistics will be collated on a
monthly basis from now on and included with this report. The
statistics for July 8 through July 31 were as follows:

Number of DSA restarts: 6
Number of DAP connections: 13
Number of DSP connections: 0
Total number of operations: 41
DAP Operations: 41
DSP Operations: 0

Looking to the Future
---------------------

As the pilot gains momentum, it may be necessary to provide access
from non-Unix based systems. One possible method of achieving this
might be to use a "lightweight" DUA package, linked into a server
based here at NIST. Several of these packages are available, eg
for the Macintosh and the PC. They use a stripped down form of the
Directory Access Protocol to communicate with a server running on a
larger system. This server then formulates full DAP operation
requests and ships them out to a DSA over the full protocol stack.

PARADISE
--------

The last few months has seen the addition of several new countries
to the international pilot: Brazil (Federal University of Rio
Grande do Sul, Porto Alegre), Czechoslovakia (Institute of
Automation & Communication, Banska Bystrica (Slovakia)) and Greece
(Institute of Computing, Heraklio (Crete)). In addition the new
states of Slovenia and Croatia are ready to register as c=SI and
c=HR but will temporarily be listed as localities under the root.
This is because the old ISO codes are compiled into ISODE 7.0, and
so the new codes would not be accepted by DSAs running the old
software. As of today, eight universities in Poland have joined
the pilot. All these countries are running QUIPU DSAs. Keen
interest is being shown in Hungary, Korea and Turkey who are all
expected to run servers in the near future.

Internet Monthly Report July 1992


The latest version of the PARADISE International Report (#3) is now
available in hard copy as well as from the info-server. In
addition to the country status notices, the report contains
articles on the following:

o Corporate Concerns
o Service Providers
o DSA Survey

The project has also produced a number of metrics reports over the
last few months which are (or will shortly) be available from the
info- server (info-server@paradise.ulcc.ac.uk). These are:

o DSA metrics
o DUA metrics
o Pilot metrics

All three of these documents will be on rfc track.

In addition to the near-conformance testing being carried out by
the PTT Research Labs in the Netherlands, the project has been
directly involved in interworking discussions and testing with ICL
(UK), Siemens Nixdorf (Germany), U.COM X.500 (France) and DirWiz
(Italy). Details of this work are contained in the first
interoperability report. Also related to this activity, the
project has produced a DSA survey of over 20 implementations. This
is available as part of the International Report or electronically.

"de" the PARADISE Directory Enquiries is available interactively
from the central server (128.86.8.56, type dua at the login:
prompt), or as part of ISODE 8.0. The project issued a third
release of the software last month, which incorporates ufn
searching, read/list opertations when accessing non-QUIPU DSAs (eg
in France), and locality/ state searching.

The project is also piloting a new tool, "idm" the interactive
Directory manager, which will be run centrally (128.86.8.56, type
idm at logi: prompt) and released to local sites on request. This
tool allows users (with appropriate access control) to add new
organsiations into the Directory and then to add, modify or delete
entries. It is seen as an ideal way to help SMEs (small to medium
size enterprises) actively participate in the pilot, as well as a
tool to allow users in large organisations to have limited access
to their own entries. Time will tell ..
