ANSNET/NSFNET BACKBONE ENGINEERING
----------------------------------
Network Status Summary
======================
Routing software changes were made to work around problems due to
increased memory utilization associated with forwarding table
growth on ANSnet. This is a temporary workaround pending the
deployment of gated routing software on ANSnet in early February.
Following the completion of the phase-5 upgrade in December,
overall T3 network stability increased to a 12 month high in
January '94. Overall Internet stability (as measured by external
route flapping) continued to decrease in January.
January Backbone Traffic and Routing Statistics
===============================================
The total inbound packet count for the T3 network (measured using
SNMP interface counters) was 45,786,027,182 on T3 ENSS interfaces,
down 0.5% from December. The total packet count into the network
including all ENSS serial interfaces was 53,834,709,296 up 2.9%
from December. The maximum number of destinations announced to the
T3 network during January was 16,281 up 9.9% from December. The
number of network destinations configured for announcement to the
T3 network but were never announced (silent nets) during January
was 5,462.
Rcp_routed Routing Software Changes
===================================
Paging problems experienced due to memory used for route computa-
tion began to appear on other ENSS. Previously this problem had
only been observed on ENSS136 (11 external peers). Changes to
rcp_routed software were deployed to reduce memory usage and avoid
a problem where router memory allocation for route download spooling
could cause page thrashing. Release notes are available for
anonymous ftp at ftp.ans.net:/pub/info/t3-rcp_routed/Release-Notes.
Cooper [Page 7]
Internet Monthly Report January 1994
Routing Stability Measured on the T3 Network
============================================
Internal routing stability measurements are made by monitoring
short term disconnect times (disconnects of five minutes duration
or less). This is intended as a measure of overall system
stability rather than complete connectivity. January showed a
considerable improvement over past months:
MONTH overall excluding configs
------ ------- -----------------
January 99.1% 99.5%
February 99.0% 99.5%
March 97.5% 99.1%
April 96.1% 97.2%
May 97.4% 98.0%
June 95.5% 96.6%
July 97.3% 97.7%
August 97.5% 97.9%

October 98.0% 98.3%
November 97.2% N/A
December 96.6% N/A
January 98.7% N/A
The node that contributed to the most instability in January was
ENSS134 due to two consecutive days in which that node suffered
from memory page thrashing (rcp_routed problem discussed above).
This was followed by E205, a customer site which agreed to be used
for early deployment of gated routing software. This node was
switched between rcp_routed and gated software a number of times to
test gated. The node ENSS177 had numerous power problems and one
other node, ENSS133, experienced over one hour of instability. For
most nodes, January was very stable, with only 13 nodes reporting
more than 30 minutes of instability and 28 nodes reporting over 15
minutes. This histogram of overall stability recorded by each node
over the last 12 months is as follows:

There has been steady increase in route flaps associated with
external networks over the course of the last 12 months. The
measurement method is described in:
ftp.ans.net:/pub/info/routing-stats/ExternalRouteFlapReports
This report measures overall Internet stability associated with the
number of times networks are announced as unreachable. The
following represents the monthly totals in terms of number of
networks declared unreachable per hour during the last 12 months.
January 844 May 1134 September 2395
February 876 June 1560 October 2272
March 1104 July 1815 November 2321
April 1038 August 1874 December 2008

Plots of the internal routing stability, external peer session
stability and external route flap are available as the files:
ftp.ans.net:/pub/info/routing-stats/internal.ps
ftp.ans.net:/pub/info/routing-stats/external.ps
ftp.ans.net:/pub/info/routing-stats/flap.ps
External Internet route flapping increased to a new monthly high in
January. Three destinations were announced as unreachable over
5,000 times (1 US). Another 8 destinations were announced as
unreachable over 1,000 times (4 US). Another 179 destinations were
announced as unreachable over 500 times (72 US). Another 1045
destinations were announced as unreachable 100 times or more (250
Cooper [Page 9]
Internet Monthly Report January 1994
US). 1917 destinations were announced as unreachable 50 time (302
US) and 12,872 destinations were announced as unreachable 1 to 50
times (8,313 US). On average 2414 destinations were withdrawn per
hour over the course of the month.
Number of times each destination is declared unreachable

Destinations announced through multiple peer networks are usually
counted once for each peer AS over which it is declared unreachable
when connectivity is lost (this is generally the case except when a
single peer transit provider loses connectivity).
There were 31 AS paths announcing over 5,000 networks as
unreachable and 29 AS paths sending over 1,000 updates containing
unreachables. These were:

There were 102 AS paths with 1,000 to 5,000 destinations announced
as unreachable, 60 with between 500 and 1,000, 240 with 100 to 500,
109 with 50 to 100, 289 with 10 to 50, and 387 AS paths with under
10 destinations announced as unreachable.
Gated BGP4/CIDR Deployment Update
=================================
We are expecting to deploy gated/BGP4 on the first AS690 router
(ENSS205) in early February. The BGP code is quite stable and has
been running on AS1133 routers since early December and we do not
Cooper [Page 11]
Internet Monthly Report January 1994
expect many problems with it. The IGP interoperability between the
two routing daemons (rcp_routed and gated) has been harder to get
working correctly.
Once the ENSS205 router is stabilized on gated, our next step will
be to deploy gated/BGP4 on ENSS160, ENSS131 (Ann Arbor) and a CNSS
(yet to be chosen) that supports HSSI interfaces and FDDI. We plan
to burn the code in for a few days and if successful, deploy this
further on ENSS136, and possibly ENSS139.
Once we have the gated code deployed on these AS690 routers that
represent the most complex configurations we need to support, the
rest of the AS690 deployment should go quickly. Once the AS690
deployment is complete, we could expect BGP4 peers of AS690 to
start to withdraw the more specific routes which are represented by
the aggregates that they are announcing.
We are working with Merit on a tool that would allow us to monitor
which more specific class-based routes (that are represented by
announced aggregates) are getting withdrawn on a weekly basis. We
hope this will allow us to debug any connectivity problems that are
reported, which may be correlated to CIDR transition.
Notable Outages in January '94
==============================
E137 (Princeton) suffered an extended power outage on 01/08.
E132 (Pittsburgh) suffered an extended power outage on 01/19.
E173 (ITESM) suffered an extended power outage on 01/30.
E257 (Creative Cybernetics) suffered an extended circuit outage
on 01/31.

December/January Reports
========================
Defense Simulation Internet
The Defense Simulation Internet (DSI) has grown to over 80 sites.
All operational user sites are now running the ST-II protocol on
the unclassified side of the network. ST 1.5 is being phased out
of the secure side of the network as well.
Cooper [Page 12]
Internet Monthly Report January 1994
An upgrade to the backbone is planned for February. Capacity will
be doubled to 3 Mbps.
The DSI supported a major demonstration at the end of November at
the Interservice/Industry Training Systems and Education Conference
(I/ITSEC). At this conference, simulators in the United States
interacted with simulators from Britain using the DSI and ISDN
circuits to connect the three sites in Britain. In addition, four
Department of Defense Dependent Schools (in Germany, Korea, and the
United States) were connected into the DSI and ran a number of
demonstrations, using both the ST-II and IP protocols.
Inter-Domain Policy Routing
During the month of December, we continued our laboratory testing
of IDPR multicast and multipath routing. We also integrated the
IDPR kernel with mrouted so that we can use IP multicast for
intra-domain multicasting and IDPR for inter-domain multicasting.
During January, we moved our testing onto DARTnet.
Scalability
Under its Defense Simulation Internet (DSI) Engineering contract
from ARPA (ASTO), BBN is tasked to study the issue of "scalability"
from the perspective of network performance and functionality. The
Distributed Interactive Simulation (DIS) user community has
ambitious goals for dramatically increasing the scale of simulated
war-fighting exercises. While the largest exercises to date have
involved less than 1000 "entities" (tanks, planes, ships, etc.),
planned future exercises may involve as many as 100,000. Changes
to both the DIS applications and the supporting network(s) will be
necessary to accommodate this growth.
During December and January, work progressed on two fronts.
Statistics were collected at two Synthetic Theater of War (STOW)
Engineering Demonstrations and in combination with statistics from
demonstrations at November's Industry/Interservice Training,
Simulation and Education Conference (I/ITSEC) are being analyzed in
order to characterize DIS network traffic and DSI performance.
Significant progress was made in enhancing the DSI network
simulator.
In December, network traffic and performance statistics were
collected during the first of several Synthetic Theater of War
(STOW) Engineering Demonstrations. The DSI statistics collection
was coordinated with the STOW participants in order to enable
correlation between performance measurements and events within the
virtual battle. High frequency collections were done at several
Cooper [Page 13]
Internet Monthly Report January 1994
points. First, for measurement of raw throughput, SNMP was used to
collect counts of packets and bytes entering and leaving router
interfaces on both the secure and unclassified subnets. Similar
statistics were collected from trunk interfaces on the Wideband
Packet Switches that make up the wide area backbone of the DSI.
Secondly, for measurement of performance specific to participating
hosts and war-fighting entities (multiples of these can be
generated by a single host), TCPdump was run on site-resident
workstations to collect full traces of simulator update traffic.
Thirdly, a special-purpose ping-like program was run among NTP-
synchronized, site-resident hosts to measure LAN-to-LAN delay every
second. The simulation participants at NRaD also collected
statistics, and it is likely that we will be combining our data
with theirs for cooperative analysis. In January, another small-
scale STOW exercise was held involving only constructive
simulators, and statistics were collected during this experiment,
as well. The data are currently being analyzed, and preliminary
results should be available soon. Unfortunately, much of the data
is classified, but the possibility of declassification is being
explored.
It is expected that initial analysis will consist primarily of
traffic characterization and network performance measurement. More
advanced analysis will follow, whose objectives will include
estimation of the benefits to be gained by various approaches to
multicast routing when combined with sophisticated application-
level filtering algorithms.
The DSI network simulator is part of the Scalability Toolset being
built in cooperation with Loral Advanced Distributed Simulation
(LADS). The network simulator is operational and is being used to
model network loading that would result from sample STOW scenarios
being generated at LADS. During December and January, we added
real-time statistics display and menu options for file handling.
The simulator is also being equipped with a graphical user
interface for easy editing and configuration of the topology of the
modeled network. In January, an interim release was provided to
the "beta test site," Lincoln Lab. This release includes real-time
display of network statistics and a load/save feature for ease in
bringing up previously stored topologies. Additional progress has
been made since then on various cosmetic attributes of the display
and tool palette.

Real-Time Multicast Applications and Communications
In the fall, we reported on the development of several new network
services -- anycast, multi-level data flows, shared streams, and
resource coordination objects. During the past few months,
o A paper describing Resource Coordination Objects was distributed
to the community and made available for anonymous FTP from
clynn.bbn.com as pub/docs/RCOs.ps).
o Some of the multicast features developed under this project have
been passed on to ISI for integration into the standard DARTnet
kernel. This includes low-level features supporting resource
coordination objects (RCOs) and multi-level data flows.
o We have modified the Video Information Server (VIS) to use three
of new network services developed under the Multipoint/Realtime
Communications project -- anycast, shared streams (built using
Resource Coordination Objects (RCOs), and multi-level data flows.
The bulk of recent efforts have been involved in the last task.
BBN's Video Information Server (VIS) can operate over wide-area
networks using only standard TCP and UDP mechanisms plus IP
multicasting. Part of the work involved considering how these new
services affect the design and efficiency of wide-area network
multimedia applications. We have compared the use of traditional
and novel network services in two areas related to the VIS: use of
distributed catalogs of video information, and digital delivery of
audio and video data.
ANYCAST
-------
Introduction
Anycasting provides a way to locate one of a set of supposedly
equivalent network resources. It differs from multicasting in that
a multicast datagram is delivered to *every* listener, while an
anycast datagram is delivered to *typically one* of a group of
listeners: the "best" one according to some criterion.
The Video Registry
The Video Registry is an anycast-based service through which video
applications can locate video resources. It consists of a trivial
relational database with a TCP-based query interface, a location
server that responds to anycast requests for the nearest registry,
and a multicast-based mechanism for redistributing locally-known
Cooper [Page 15]
Internet Monthly Report January 1994
resources to other registries.
A video resource (for example, a catalog server that lists
available video clips) sends an anycast UDP datagram to locate the
nearest video registry. At most one registry responds with a
unicast UDP datagram containing the registry's IP address. Said
resource then opens a TCP connection to that address and sends a
request to register itself. Every 5 minutes or so, each registry
multicasts to all other registries all of the resources it knows
from local registration requests. It also immediately announces
newly registered resources. Remotely registered resources not
heard about for 20 minutes are dropped.
A client application locates a registry in the same way, connects
to it, and issues a query for all the video resources of a certain
class. The registry returned locally-registered resources first,
followed by remotely registered ones. New functions in VideoLib
make it relatively simple for both client and server applications
to use the registry.
Vlens Without Anycasting
One client application that uses the video registry is vlens, which
displays a list of video clips that match supplied keywords, then
allows the user to view any clip in the list. The search itself is
performed on behalf of vlens by various video servers; vlens can
locate these servers using two methods: multicast-based or
anycast-based.
Each video server has a WAIS server that exports one or more video
catalogs (BBN's video server currently exports 11 catalogs). In
addition, each video server has a multicast catalog-query manager.
By default, vlens uses IP multicast queries. Each time the user
enters some keywords, vlens sends out a couple of multicast query
datagrams containing the keywords plus a globally-unique
identifier. The catalog-query managers receive these datagrams and
forward the query to their corresponding WAIS server (running on
the same host). If a WAIS server returns any valid matches, the
catalog-query manager sends a response datagram to the multicast
originator saying, in effect, "I have a valid response to your
query ID #<such-and-such>." Queries are idempotent; subsequently
received query datagrams with the same identifier elicit an
immediate retransmission of the above reply.
After transmitting its queries, the client application sits back
and awaits replies. After a time, it iterates through the list of
replies, opening a TCP connection to each of the responding query
Cooper [Page 16]
Internet Monthly Report January 1994
managers and saying, "Send me your responses to my query ID
#<such-and-such>." Each response takes the form of a one-line EDL
file, which vlens simply concatenates for display to the user.
Vlens With Anycasting
The above scheme is simple to implement, and takes good advantage
of the parallelism inherent in multiple catalog servers.
Nevertheless, it is obviously non-deterministic, and in practice
tends to be noticeably unreliable. The alternative anycast-based
search mechanism, enabled by running "vlens -anycast", works rather
differently.
When first started in anycast mode, vlens uses anycast to locate
the nearest Video Registry. It then opens a TCP connection to the
registry and gets a list of all resources of class "WAIScatalog".
Vlens then iterates through this list, contacting each WAIS server
at the given address and port. It forms a query to the INFO
database asking for all ".src" files, which in turn identify all
available databases; it retrieves these into a subdirectory of
/tmp. At this point vlens is ready for user input; it then takes
each user query and sends it in turn to each of the available
databases, collecting up to 250 total responses.
SHARED STREAMS
--------------
Introduction
A Shared Stream is a bandwidth reservation shared by multiple
transmitters. A conventional bandwidth reservation is made when a
single transmitter requests absolute priority use of a specified
number of bits per second between two specified network endpoints
(Note that "absolute priority use" is not the same thing as
"exclusive use.") If another transmitter makes a similar request,
it receives a separate allocation from that of the first
transmitter.
Nevertheless, in some circumstances (such as a floor-controlled
videoconference) the second transmitter doesn't really need a
separate allocation, because it will never transmit at the same
time as the first transmitter. Shared Streams are a way for other
transmitters to request access to the same stream already allocated
for the first transmitter, with the promise that their total
combined transmitted bandwidth will somehow be limited to the
original allocation.
Cooper [Page 17]
Internet Monthly Report January 1994
Registering a Shared Stream
BBN's implementation of Shared Streams works as follows:
- The first transmitter sends the Resource Reservation Daemon
(RRD) a FlowSpec detailing its bandwidth requirements.
- If the reservation succeeds, the RRD returns a Resource
CoordinationObject (RCO) ID, which consists of an IP address
followed by 32 additional bits.
- Subsequent transmitters send their local RRDs the same
FlowSpec plus the RCO ID returned to the first transmitter.
Video clients that use shared streams first agree on an alias by
which the RCO ID will be known when it becomes available. The
first client to obtain the RCO ID registers it in the video
registry under the agreed-upon alias. Later clients retrieve it
under the same alias. When the originator closes down its stream,
it unregisters the alias.
Shared Streams in XIO
We modified the XIO program, which transmits and receives JPEG-
compressed video and mu-law audio, to support shared streams. When
invoked as "xio -t -ptt -join <stream name>" argument, the XIO
transmitter interacts with the RRD and video registry, as described
above, before each connection attempt. To create a suitable
FlowSpec, XIO derives a conservative estimate of its bandwidth
requirements from the initial settings for picture size, inter-
frame delay, and quantization factor.
The "-ptt" flag causes the XIO transmitter to display a Push-To-
Talk (PTT) button; it transmits audio and video only while that
button is depressed. For our demonstration, we run XIO at three
separate DARTnet sites with at least one common segment across
which two streams must flow. Videoconference participants take
turns depressing their PTT buttons, multicasting their image and
voice to all participants.
MULTI-LEVEL DATA FLOWS
----------------------
Introduction
A multi-level data flow is an unreliable transmission in which the
transmitter tags each datagram with its importance to the overall
information transfer. For example, in a pyramid-encoded video
transmission the low-frequency data, which gives the overall shape
of the image, is more important than the high-frequency data, which
Cooper [Page 18]
Internet Monthly Report January 1994
fills in details. Faced with inadequate bandwidth, intermediate
gateways would discard the less-important datagrams first.
In the video server, we chose to demonstrate two-level video
transmission. Because we do not have a pyramid encoder, we chose
to transmit a low-resolution image with audio, and a high-
resolution image without audio. A receiver requesting a low-
bandwidth transmission would receive a complete, but small, picture
with audio. A receiver requesting a high-bandwidth transmission
would receive both streams, displaying a large image from the
high-resolution stream with the audio from the low-resolution
stream.
Multi-level Flows in XIO
We modified the XIO program to support multi-level flows. Given
the "-subflows" argument, XIO will transmit and receive audio and
video in one or two hierarchical subflows. For example, "xio -t
-subflows 01" will set up a transmitter that sends two subflows
numbered 0 and 1, while "xio -r -subflows 0" will set up a receiver
that only subscribes to Subflow 0.
Our demonstration of multi-level flow support consists of
Workstation A multicasting a two-subflow digital video stream from
a continuous audio+video source (such as a television channel) in
which Subflow 0 contains audio and low-quality compressed video
(JPEG quantization factor of 500), and Subflow 1 contains high-
quality compressed video (JPEG quantization factor of 100) only.
Workstation B receives both streams, playing the audio but
discarding the video from Subflow 0 while showing the video from
Subflow 1. Workstation C receives only Subflow 0, from which it
plays both the audio and video data.

CONCERT
-------
In December, the HPCC research group began evaluating the resource
requirements for incorporating the Compressed Video
Interoperability Protocol concept from Viewpoint Systems Inc. into
a general interoperability framework for packet-based video
conferencing. This intention was conveyed through the following
statement:
"MCNC, in Research Triangle Park, N.C., intends to incorporate the
Compressed Video Interoperability Protocol concept into a general
framework being developed that will foster interoperability among
Cooper [Page 19]
Internet Monthly Report January 1994
different video coding schemes. Supporting interoperability is
consistent with the objectives of MCNC's existing Packet Video
Project and associated Packet Video Forum. A detailed estimate of
the scope of the effort and the required implementation resource is
underway."
In January, the ATM testing group and the HPCC research group
successfully tested interoperation between 2 Fujitsu SMX-6000
broadband service multiplexors and the Fore ASX-100 switch, at OC3c
link speed. A lesson learned was that applications should not use
VCIs 14,15, and 65535 to avoid conflict with with internal use by
the switch (software version 2.2.5).

CSUNET
------
CSU was awarded a CALREN grant from Pacific Bell. The grant will
provide Pacific Bell ATM services at no charge for a two year
trial. The trial will be a joint venture between the California
State University and University of California systems. San Jose
State University is the only university in the state of California
now offering a Masters in Library Science. The trial will exploit
ATM services for transfer of video images and JPEG (2Mb-8Mb) video
between three CSU campuses. Instructional facilitators and
cirriculum designers from CSU and UC will be collaborate to form a
new M.S. in Library Science to be taught anywhere in California.
On the new connections front, CSUnet continues to attract new
education, research, and state agencies for connection to the
Internet. The focus remains on districts, libraries, county
offices of education and community colleges rather than individual
high schools because it is often the case that administrative
systems connecting the high schools can be re-used for instruction.
Latest members include:
The County of Riverside (the entire county system will provide
connections to county and city agencies)
East Side Unified School District (San Jose area)
Ventura County Superintendent of Schools
Butte College (Chico area)
City College of San Francisco
Yosemite Community College District
CSU Stanislaus Off-site Center
San Joaquin Valley Library system
Sonoma County Library system
California Community Colleges Chancellor's Office

Internet Monthly Report January 1994
CSUnet has installed a frame-relay hub in Los Alamitos and has
contracted GTE to provision yet untariffed services. Pacific Bell
also is providing new frame-relay connections. The "public" net is
being used instead of our private net for these new 56K connections
because of the low pricing by the RBOCs.

REGISTRATION SERVICES
Significant Events
------------------
InterNIC Registration Services received 2,320 calls in January,
mainly as a result of an article in _USA Today Weekend_ magazine
January 23, 1994. The majority of these calls requested
information on connecting to the Internet.
A number of service providers have begun to implement inverse
addressing on their existing CIDR blocks. Registration Services is
working with each of these providers in transistioning inverse
addressing so no customers are inconvenienced.

RARE SECRETARIAT
----------------
NEWS FROM RARE (Reseaux Associes pour la Recherche Europeenne)
CEENet
A new international networking association has recently been
established: CEENet, of which the members are at the moment: ACONET
(Austria), UNICOM (Bulgaria), CARNet (Croatia), CESNET (Czech
republic), NASK (Poland), SANET (Slovakia) and UARNet (Ukraine).
More CEEC members are expected to join shortly. The members are
networking organizations that represent their country with
authorization from their government. CEENet's role is to coordinate
international aspects of academic and research networking in the
CEEC region.
CEENet was admitted as International Membership of RARE. CEENet has
chosen RARE as the umbrella body for networking for research in
Europe. A planning group has been set up to discuss how best to
coordinate infrastructure planning and to function as a point of
reference.
RARE/EARN merger
With the overall target of strengthening user representation in
Europe the Executives of EARN and RARE are progressing a merger
between the two Associations.
RARE Signatory of ICT MoU
RARE has signed the Memorandum of Understanding on Partnership in
Information and Communication Technology (ICT), a EC initiative
targeting enhancing user involvement in ICT.
Elections Executive Committee
Kees Neggers was elected President, Paul Van Binst Vice-President
and Peter Bakonyi Treasurer. Sven Tafvelin and Christian Michau are
the new members of the Executive Committee. The new RARE Executive
Cooper [Page 36]
Internet Monthly Report January 1994
Committee takes office on 1 May 1994.
RARE Technical Programme
RARE will establish a project involving maintenance of the
reference implementation of World Wide Web and will seek funding
for this project. The activity will be coordinated with Mosaic.
The RARE Technical Committee is planning a Europe wide effort to
coordinate the INIX and D-GIX activities and will raise the funding
for this coordination effort.
RARE Publications
RARE has published its seventh in its series of Technical Reports:
"RTR7 (RFC1502) has appeared: X.400 use of Extended Character
Sets". The report was written by Harald Alvestrand from UNINETT,
Trondheim in Norway. The author believes that this specification
can easily accomodate the use of any character set in the ISO
registry . Also the guidelines given for choosing character sets
will help interworking.
This is the second Technical Report to be published as RTR and
Internet RFC at the same time. Paper copies of RARE publications
are available from the RARE Secretariat. Electronic versions can be
obtained from the RARE document server.
Conferences and seminars
INET'94/JENC5 Conference The annual Joint European Networking
Conference (JENC) will be held in conjunction with the INET'94
conference in Prague this year. This event will take place on 13-17
June in Prague, the capital of the Czech Republic. The conference
committee of INET'94/JENC5 is chaired by Geoff Manning (UKERNA,
responsible for JNT programme), while Bernhard Plattner (ETH,
Zurich) again chairs the programme committee. Local arrangements
are in the hands of Jan Gruntorad (Czech Technical University).
At the moment the organizers are in the process of composing the
programme for the conference which will become available in March.
If you would like to receive a copy of the programme, please have
your email address added to our distribution list ('inet-jenc-
request@rare.nl'). Already available from inet-jenc-request@rare.nl
is the Call for Papers, which gives an overview of the various
tracks and topics that will be presented and discussed in Prague.

Internet Monthly Report January 1994
EARN is organizing a Network Services Conference in London, from 28
to 30 November, subsequent to which a large RARE Working Group
meeting will take place.
The final report on the NATO Advanced Networking Workshop on
Research Networking in Central and Eastern Europe that took place
in Budapest last Autumn will be available from the fileserver,
soon. The Workshop was very well attended and regarded as very
useful by several countries.
HIGH SPEED NETWORKING SYMPOSIUM
The 3rd Symposium on High Speed Networking for Research in Europe
was held on 2 February 1994. The regis tration process for this
symposium already showed a large interest with 148 participants
from 24 countries, 2 even from Japan, but even more experts
attended during the day. The attendees' comments were full of
praise of this unique opportunity to exchange and review High Speed
Networking issues.
Presentations
There were 14 high-level presentations on various subjects such as:
- engineering trans-oceanic 44 MBs TCP/IP networks
- high speed services plans applied to backbone technology
- coordinated ATM testing and services within Europe
- multimedia experiments in SGN, the Stockholm Gigabit Network
- LARA, an Interconnection of ATM products
- ATM experiments for High Rate Space Telemetry Transportation
and more.
General
The symposium was especially of interest to experts in the field of
ATM. It brought together the practical experience of ATM from the
research, PNO and service communities, as well as the experience
from major commercial user organizations.
Examples of on site, intersite and even international testing with
ATM were covered, as well as research work related to supporting
ATM at higher speed. Some of the current gaps in ATM
implementations were identified, but it was noted that technical
specifications in these areas had been, or were being, produced.
An overview of some of the presentations
Dr Leslie Clyne reported on the work of the RARE ATM Task Force
which is coordinating ATM developments between RARE organizations,
Cooper [Page 38]
Internet Monthly Report January 1994
and is acting as a forum for exchange of information and
experience. Coordination of input to the proposed European ATM PNO
pilot is also being carried out.
Dr Guy Almes described some of the network engineering issues
associated with the deployment of a Trans-oceanic DS3 link between
mainland USA and Hawaii.
Dr Juha Heinanen presented the FUNET project which links ATM sites
in Finland and is providing pilot services. He identified both the
potential of ATM, and some of the technical shortcomings in areas
such as agreement on protocol stacks, implementation of traffic
policing and dynamic signalling.
Dr Leslie Clyne reported on the national UK SuperJANET project
which is using a combination of networking services and
technologies including SMDS, and ATM over PDH/SDH, to provide high
speed networking to over 50 sites. During the 1st half of 1994 some
50 sites are getting SMDS connections at 10 Mbps, and at least 12
sites will have ATM switches connected to the 100+ Mbps WAN
bandwith.
Prof. Bjorn Pehrson described the Stockholm SDH Gigabit testbed
which is facilitating research into new multimedia experiments
requiring 100's of Mbps of intersystem bandwith.
Dr Jaques Prevost presented previous work on ATM in the French
research community and the recently approved plan for national ATM
testing and deployment.
Mr Jalal Samain descri bed the BETEL project which in 1993
transferred ATM cells between France and Switzerland. LAN's were
connected using an ATM switch and Virtual Paths between routers.
Mr Kees Neggers described the plan for SURFNet 4, which is an ATM-
based technology pilot to connect 2, then 9 sites in the
Netherlands.
Ms Jocelyne Lemagnen described the extensive work done by the LARA
consortium in France on LAN and WAN ATM testing. In particular the
LAN environment used ATM switches from many vendors, and a variety
of hosts were connected. Some of the technical gaps in
specifications were identified.
A presentation by Alcatel explained the current research trends on
development of optical ATM switches which would allow use of the
technology above the current limitation of Gigabit speed for access
ports.
Cooper [Page 39]
Internet Monthly Report January 1994
Mr Rumeau described the use of ATM for the support of high speed
(50 Mbit/sec) Constant Bit Rate services to interconnect ground
sites and transfer bulk data from satellite experiments.
Fourth Symposium on High Speed Networking
The announcement of a fourth symposium on High Speed Networking for
research in Europe in 2 or 3 years' time was warmly welcomed by
all. The proceedings will be published in the next issue of CNRE.
