RESOURCE DISCOVERY AND DIRECTORY SERVICE
----------------------------------------
The Internet Research Task Force research group on Resource
Discovery has been developing and experimenting with the Harvest
system for the past 1.5 years.
Harvest provides an integrated set of tools to gather, extract,
organize, search, cache, and replicate relevant information
across the Internet. With modest effort users can tailor
Harvest to digest information in many different formats, and
offer custom search services on the Internet. Moreover, Harvest
makes very efficient use of network traffic, remote servers, and
disk space.
In the past few months we have made significant improvements to
the system, allowing well-controlled specifications of the
information gathering workload, much better gathering and
indexing performance, support for more data formats, more
sophisticated caching and replication, ports to popular
platforms, and much more easily installed and used binary
distributions of the basic system. At present we are working on
extending the system to support taxonomies and query routing,
more complex data models, interfaces with other popular systems
and products (such as Verity's and WAIS Inc.'s search engines,
SGML, and SQL search engines), more customizable searching
schemes, non-textual index/search engines, and a number of
experiments concerning system scalability. We are actively
pursuing collaborative efforts with other projects in all
sectors - commercial, government, academic, and others.

papers, software, and documentation) from

ANSNET/NSFNET BACKBONE ENGINEERING
----------------------------------
FEBRUARY BACKBONE TRAFFIC STATISTICS
The total inbound packet count for the ANSnet (measured using SNMP
interface counters) was 57,423,075,598 on T3 ENSS interfaces, down
19.23% from January. The total packet count into the network
including all ENSS serial interfaces was 72,065,096,991 down 13.41%
from January. The decrease is due to the on-going decommissioning
of the NSFNET backbone service.
ROUTER FORWARDING TABLE STATISTICS
The maximum number of destinations announced to ANSnet during
February was 22,292 up 5.22% from January.
The number of network destinations configured for announcement to
the ANSnet but never announced (silent nets) during February was
23,269

NEW EBONE-EUROPANET GATEWAY
Since 1 February the fourth consecutive interconnect arrangement
between EuropaNET and Ebone has been in operation. As the capacity
of the previous gateway was insufficient, the new gateway has a
capacity of 1 Mbps, and will shortly be upgraded to 1.5 Mbps. The
cost is shared between Ebone and some of DANTE's customers. The
current arrangement will cover the first 9 months of 1995.
Cooper [Page 9]
Internet Monthly Report February 1995
At the same time DANTE regrets not to have been able so far to
persuade EUnet to serialize their connection to EuropaNET. DANTE
has been providing EUnet with a free 64 kbps access, but in
practice much more capacity is used. Therefore DANTE asked EUnet to
increase their connection rate accordingly and to serialize the
connection in October last year. Unfortunately, DANTE can not
indefinitely offer free and unlimited connectivity to some networks
while charging others.
HIGH SPEED PROGRESS
While the EuroCAIRN study is now in the hands of the EuroCAIRN
Committee DANTE has already taken the next step on the road to a
high speed network for European research. DANTE submitted an
outline proposal under a joint initiative as part of the EC Fourth
Framework Programme of DG III F and DGXIII C to support the
European interconnection of national research and university
networks at 34- 155 Mbps. The initiative is an integral part of the
existing Call for Proposals for the Information Technologies
Programme (Esprit) and the Telematics Application Programme. DANTE
will act as coordinating partner in a consortium together with a
number of national research networks. A decision on which projects
will be awarded funding will be made be made in the second half of
1995. Obviously DANTE is keen to get the opportunity to execute the
implementation plan it has presented as part of the EuropCAIRN
report.
DANTE AT CEBIT
DANTE is pleased to announce that, by courtesy of DFN, it will be
present at CeBIT, the leading annual IT event in Hannover, Germany.
DANTE was invited to share the DFN stand. DANTE will take the
opportunity to increase visibility of its own activities and
European research networking in general. In particular DANTE will
spread the word on its 'high speed' activities so far. DFN and
DANTE can be found in Hall 22, Stand D36. More information can be
found on a special www page, URL:
http://www.dante.net/CeBIT/CeBIT.html
VIRTUAL PROJECT LIBRARY
DANTE is taking part in an EC Information Engineering Feasibility
Project initiated by the French company Matra Marconi Space. The
project is called Virtual Project Library and it sets out to create
a mechanism which will enable project participants distributed all
over Europe working together on a project to access, use and store
project information over the network. This may sound very familiar
to the networking community but in the commercial world the
Cooper [Page 10]
Internet Monthly Report February 1995
Internet is not yet the standard information medium, security being
one major concern. DANTE was invited to join as partner to assess
and advise on the pan-European networking options and limitations
for creating such a mechanism. The kick-off meeting for the seven-
month project took place in February.
NEW STAFF
Vincent Berkhout (NL) started work for DANTE on 16 January 1995. He
will be working as Applications Engineer. Initially he will
concentrate on directory issues. Vincent graduated as 'Telematics
Engineer' at the Hogeschool Utrecht in 1992. For his final thesis
he worked at SURFnet doing research on the technical infrastructure
of X.500. After that he joined the post-graduate Technology
Designer program at the University of Twente where he worked as a
member of the Network Management discipline group.

INTERNIC

INTERNIC DIRECTORY AND DATABASE SERVICES
As of February 28, InterNIC Directory and Database Services took
over support of some of the services previously supported by
InterNIC Information Services. The InfoGuide will be available on
ds.internic.net (pending resolution of some copyright issues), and
some popular mailing lists will move as well.
The scout-report and net-happenings mailing lists have been moved
to DS machines. The mailing list transition is causing some load
problems at the moment (scout-report, for example, has 20,000
recipients). We are ordering additional hardware to handle the
Cooper [Page 11]
Internet Monthly Report February 1995
load generated by the mailing lists and we expect their performance
to be back to normal soon. The lists are held on a machine named
dsmail.internic.net, but we have aliases in place so requests sent
to [email protected] will be handled properly.
To minimize impact from this changeover on InterNIC users, the name
is.internic.net has been changed to point to the Directory and
Database Services machines and we will maintain the same directory
structure for the IS information that it had on the IS machine.
Thus users will be able to continue to use URLs and Gopher links to
files and directories on is.internic.net. This also means that
subscription requests for the mailing lists can still be sent to
[email protected]
There are no changes to the existing service offered on the ds
machines.
A reminder - if you would like to help the Internet community find
a resource that you offer, send mail to [email protected] and
we will send information about listing your resource in the
Directory of Directories.

INTERNIC REGISTRATION SERVICES
I. Significant Events
InterNIC Registration Services assigned over 10,056 network
addresses and registered over 4,190 domains. Three top level
domains were registered this month for Anguilla (AI), Cote d'Ivoire
(CI), and Guam (GU).
Knowledgenet, Inc. has filed suit against Network Solutions and
David L. Boone over the name knowledgenet.com. Network Solutions
has engaged outside counsel to represent us in this suit. Due to a
continuance, the next court filing has been pushed back to early
March. This case could establish precedence that refutes InterNIC
Registration Service's current policy of first-come first served by
binding trademarked names with a domain name.
During the month of February, increased volume of requests has
increased the backlog from 10 days processing time to 15 days
processing time. There are approximately 5,000 new domain requests
in the queue to be processed. Adjustments in processes/staff are
being made, as well as ordering additional equipment to continue to
accommodate the tremendous growth currently being experienced by
Registration Services.
Cooper [Page 12]
Internet Monthly Report February 1995
Mark Kosters attended the two (2) day NANOG meeting in Denver,
Colorado the week of February 6, 1995. Mark gave a presentation on
the status of InterNIC Registration Services (RS) demonstrating
its' current load. He also, participated in IP allocation and
assignment strategies.
II. Current Status
During the month of February 1995, InterNIC Registration Services
received communications as shown below. The majority of the

NETSTATION
==========
Recent work on the Netstation Project has focused on end-to-end
protocols which facilitate efficient implementation. Specifically,
we have been working on the design and implementation of a
transport protocol, DTP, that is optimized for fast intra-LAN round
trip times, and the design of internet protocol mechanisms which
would facilitate high performance wide-area transport protocols.
Cooper [Page 13]
Internet Monthly Report February 1995
A draft document describing the transport protocol, DTP, will be
complete as results of the protcol implementation become available
to support, or refute, the protocol design choices. A document
describing mechanisms to support a zero-copy internet checksum is
also in preparation.
DTP: A HIGH-PERFROMANCE TRANSPORT PROTOCOL
The properties of data transfer fidelity, order preservation and
execute once-only semantics are provided through the physical
design of a system bus and are taken for granted by software
developers. Those properties are not provided by general-purpose
networks. To successfully control a device across a network, those
properties must be explicitly provided via protocols. A reliable
transport protocol can ensure data fidelity, preserve ordering and
provide at-most-once delivery of RPC messages.
The rate at which RPC messages can be issued by a source host to a
destination host is bound from above by the rate at which the
source transport layer can send a message and receive its
acknowledgement from the destination transport layer. Since
commands to devices are often serially dependent, where the result
of one command must be known before the next can be issued,
effective substitution of a network for a system bus requires
achieving very short RTTs in the transport layer.
OVERVIEW OF A DEVICE TRANSPORT PROTOCOL
A transport-layer protocol that is designed specificly for the
control of devices over a network differs from a general-purpose
transport-layer protocol such as TCP. The principal objectives are
to satisfy required semantic communications properties for a
Netstation device (NVD) operation while minimizing protocol-induced
delays, both in the transport and application layers.
Other transport-layer protocols have been defined that address
somewhat similar application requirements. Perhaps chief among
these are VMTP and the Reliable Data Protocol (RDP). The reasons
for not using TCP for the control of NVDs echo the reasons that RDP
was developed. Quoting from the RDP document RFC 908: "TCP is best
suited to an environment where there is no obvious demarcation of
data in a communications exchange. Much of the difficulty in
developing a TCP implementation stems from the complexity of
supporting this general byte-stream transfer, and thus a
significant amount of complexity can be avoided by using another
protocol. This is not just an implementation consideration, but
also one of efficiency."
Cooper [Page 14]
Internet Monthly Report February 1995
The architecture of DTP builds on concepts found in VMTP, RDP and
TCP, but is designed to take maximal advantage of the expected
Netstation environment. In particular, emerging gigabit LANs
provide an environment that is friendly to operation of a reliable
transport protocol in several ways: (a) the delay*bandwidth product
is generally shorter than a packet, (b) maximum packet lifetime is
of little concern, (c) the cost of routing a packet is small and
bandwidth is plentiful, and (d) packets are protected by a hardware
checksum.
A judgement was made that the majority of connections between
devices and their owners are likely to be intra-LAN. If one
accepts this premise, special attention should be paid in the
transport layer to minimizing RTT for this class of traffic. DTP
identifies messages sent across intra-LAN connections, which allows
different flow-control and processing algorithms to be used for
intra-LAN traffic.
The design of DTP focuses on minimizing the end-to-end delay when a
source application sends a message to a destination application.
This is distinct from attempting to maximize bandwidth utilization
or to minimize long-term transport-layer overhead. In determining
DTP's features and formats, uppermost was the consideration of how
to define the protocol to minimize the RTT between transmission of
a reliable message and its acknowledgement.
ZERO-COPY PROTOCOL STACKS AND CHECKSUMMING
A primary source of overhead in protocol processing can be
attributed to operations that read and/or write all, or most, of
the bytes in a packet. Examples of these operations are (1) digest
or encryption security functions, (2) buffering and copying between
different protocol layers (network -vs- transport) or
implementation layers (application -vs- operating system), or (3)
data fidelity checksum algorithms.
A protocol implementation that eliminates those per-byte costs is
referred to as a zero-copy protocol stack; the ability to perform a
particular operation without the per-byte overhead is a zero-copy
operation. We are concerned about checksum functionality, and
mechanism to support zero-copy checksuming in the next-generation
TCP/IP protocol stack (IPv6, TCPv6 and UDPv6).
The principal advantage of a zero-copy stack is increased
performance. A 20MHz Myricom LANai interface processor can scan
application buffers for a packet to send, prepare that packet,
transmit it with CRC and service a send-done event in 51 machine
instructions. As a result, a source application running on a
Cooper [Page 15]
Internet Monthly Report February 1995
SPARCstation-10 can send IP/UDP RPCs individually, at a rate of
70K/second across the network into a destination application. This
performance is a result of (1) a shared-memory interface between
application and network interface, and more importantly (2) the use
of the zero-copy link-layer checksum provided by hardware
interface.
Only in cases where both the source and destination nodes are on
the same LAN can end-to-end data protection can be provided by a
link-layer checksum, rather than a combination of network and
transport checksums. A high level of performance is possible
because packets are not copied and neither the network layer nor
the transport-layer need to scan them to calculate checksums.
However, this zero-copy technique does not easily extend to cover
situations where source and destination nodes are on different
LANs. This sharply restricts the domain within which the better
performance is available.

ATOMIC-2
========
This month the ATOMIC-2 project completed Web pages, available at:
<http://www.isi.edu/div7/atomic-2>
Everything in this and coming reports will be available on-line in
these web pages. Work continues on the following topics:
LAN Installation
Applications Demonstration
File Server
Applications Bandwidth
Next month we will have additional information on
ATOMIC-ATM Gateway
ATOMIC Interface Design
ATOMIC-2 LAN INSTALLATION
This month the ATOMIC LAN replaced the Ethernet connection on three
office workstations (Sun SPARC 10/41, 10/51, and 20/50) at ISI. The
Ethernet to these hosts is completely disconnected, and they have
been running continuously for three weeks. They are currently
gatewayed through a Sun SPARC-2 to the division Ethernet, including
the MBONE. This will be replaced with the ATM gateway under
Cooper [Page 16]

development. We expect that over the next two months a total of 65
workstations will be on the ATOMIC LAN, and the Ethernet will exist
to support only those hosts for which Myricom interfaces have not
yet been implemented.
ATOMIC-2 APPLICATIONS DEMONSTRATION
PVM (Parallel Virtual Machine) [1] supports distributed and
parallel computing applications. PVM 3.3 has been installed on the
ATOMIC LAN. We measured the communication bandwidth and latency
between two PVM tasks on this LAN, between two Sun SPARC 20/50
hosts. The task-task latency has a 1.15 ms overhead (of which 0.7
ms is ATOMIC LAN overhead), the remainder determined by the packet
length and bandwidth. The bandwidth is 25-30 Mbps for 2 Kbyte
packets, and drops to 10 Mbps for 0.5 Kbyte packets. TCP can reach
peak bandwidth 50 Mbps in the ATOMIC LAN, the PVM's peak bandwidth
is lower due to the extra memory copy between the PVM buffer and
user data buffer.
In order to explore the high ATOMIC link-layer bandwidth and avoid
the kernel protocol stack overhead, our next step is to improve PVM
performance by implementing PVM message passing routines using the
Myrinet API, instead of TCP.

Ridge National Laboratory, Sep., 1994.
ATOMIC-2 FILE SERVER
We are continuing our investigation of NFS performance, in order to
determine the ATOMIC-2 File Server design. Our measurements
indicate that NFS write bandwidth is bounded by both the Sun RPC
protocol that commonly implements it, and internal interactions
with the BSD file system.
RPC limits the bandwidth because only a single request/response can
be outstanding to any given process. Sun's implementation of NFS
uses multiple processes to effectively overcome this limitation on
an Ethernet. On the higher bandwidth ATOMIC network, the overhead
of context switching and demultiplexing packets to these processes
limits the bandwidth to less than observed TCP or UDP user-user
bandwidth. Essentially, the low bandwidth solution is bottlenecked
in comparison to the high bandwidth network. We believe it would
be more efficient to have a single process fill a sliding window
than use multiple processes doing RPC.
The BSD file system also interacts with NFS, particularly when
writing disk blocks. When a file is read, then a request for the
Cooper [Page 17]
Internet Monthly Report February 1995
block the user is interested in is issued immediately, potentially
along with several read-ahead blocks. This pattern is fairly
predictable, and maps closely with the read calls that the user
makes. When a disk block is written, it is written to the BSD file
cache, and flushed out to the server when the paging system needs
one of the disk cache pages, or notices that the page has been
dirty for some time. A block written by a user can sit in the file
cache for some time before the page daemon flushes it to the
server. Furthermore, the paging daemon and the user writes are
entirely disconnected; the pattern of writes the user issues and
the order and timing of the blocks that are flushed to the server
by the page daemon are basically independent. The combination
implies that it is harder to pipeline write requests than read
requests. (There are good reasons to cache file writes, notably
not bothering the server with writing short-lived temporary files,
but it impacts NFS performance as well.)
We are investigating strategies to both implement NFS using a
higher bandwidth transport protocol and to pipeline writes more
effectively.
ATOMIC-2 APPLICATION BANDWIDTH ACCESS EXPERIMENTS
Previously most of the performance measurement tools in use on the
Atomic-2 project have made use of the standard SunOS API, the
socket interface, which provides user programs access to TCP/IP and
UDP/IP. To develop an understanding of how bottlenecks might be
avoided, some of these applications are being augmented to
optionally use the Myrinet API, which will allow the user program
to send raw Myrinet packets and bypass the kernel.
Using a pre-release version of Myricom's dual-path driver, the IP
traffic and Myrinet API traffic have been able to run
simultaneously on the ATOMIC LAN. The performance of running
simultaneous IP and API traffic is critical in assisting our high-
performance protocol research. In our experiments, the IP traffic
and API traffic were running in the same direction between two Sun
SPARC 20/50s connected through one 8-port switch. We found that the
performance dropped by 10-30%, even though we were running only one
type of traffic at a time through the dual-path driver.

Native API packets 220 Mbps 150 Mbps
UDP/IP 60 Mbps 54 Mbps
TCP/IP 50 Mbps 44 Mbps
Cooper [Page 18]
Internet Monthly Report February 1995
Two possible reasons for the decrease in throughput are additional
overhead due to interface demultiplexing and lack of sufficient
buffer space (because the space is fragmented into two packet
queues).
ATOMIC-2 SECURITY
Last month the performance analysis of MD5 was completed. This
month we began analysis and selection of alternatives that can
support ATOMIC LAN bandwidth. This analysis is proceeding with MD2.
Initial analytical results indicate that MD2 should run 20 times
slower than MD5, which is too slow for the ATOMIC LAN (38 Mbps on a
SPARC 20/50, where UDP is 50 Mbps). Measurements indicate that the
current optimization of MD2 runs 30 times slower than MD5; because
a speedup of only 50% is possible, this work is not being pursued.
We are instead evaluating other authentication algorithms more
suitable to high-speed implementation in software and/or hardware.

RSVP
====
After the January release of RSVP version 1, a number of useful
comments came in which we have incorporated. Most of these
suggestions dealt with the portability of the code. The most
extensive of these came from MIT which ported RSVP to DEC alpha
machines and Intel based PC's. These changes allow RSVP to run on
64 bit architectures such as the alpha and "little-endian" machines
such as the PC and the alpha. We are testing the interoperability
of these versions. Other input came from Bill Nowicki at Silicon
Graphics who was porting RSVP to SGI machines.
Another remaining issue for the complete version 1 RSVP is the
support of tunnels. Such a tunnel exists between the Xerox PARC
DARTnet router and most of the PARC hosts. We are using UDP
encapsulation on a well-known multicast IP address to communicate
between hosts and routers. This is now working and we are able to
make reservations both into and out of Xerox PARC hosts.
We are preparing an RSVP Web page. The page is ready and the
appropriate links will be installed shortly on the ISI home page.

MERIT/NSFNET ENGINEERING
------------------------
This report summarizes recent activities of Merit's Internet
Engineering and Network Management groups on behalf of the Routing
Arbiter (RA) Project and the NSFNET Backbone Service Project.
Merit has sent a 60-day termination notice for the NSFNET Backbone
Service to ANS. The backbone ENSS's will be turned off at midnight
on April 30 in each respective time zone. Merit and the regionals
have enjoyed a successful collaboration for many years, and we look
forward to continued joint successes in the brave new world of
post-NSFNET!
Many regionals are obtaining interregional Internet service from
Network Service Providers, and have moved off the T3 NSFNET
backbone. Merit will now gradually discontinue the T1 "safety net"
that has backed up regional connections to the T3 NSFNET for
several years.
The Routing Arbiter Project's Route Server at MAE-East has begun to
pass actual routes to its peers. Among the AS's receiving routes
are MCI, PIPEX, and Net 99. Many thanks to these AS's for helping
move the new technology along!
Merit has ported PGP version 2.6 into the RIPE routing registry
software. The new privacy feature makes it possible to use PGP's
popular cryptographic algorithm to authenticate data submitted
through e-mail to the Routing Arbiter Database (RADB) and other
Cooper [Page 24]
Internet Monthly Report February 1995
RIPE-181-style registries. To implement PGP, simply enter 'PGP-
FROM my.email.address' in the RADB Maintainer object's 'auth:'
field. You then use a public domain PGP client to sign your e-mail
with your secret key. The RADB software uses your public key to
verify your signature. The PGP encryption schema is known to be
very difficult to break. PGP can also provide confidentiality by
encrypting any data in such a way that only the recipient can read
the message. For more information, contact Laurent Joncheray at
Merit ([email protected])
As part of the process of replacing the NSFNET Policy Routing
Database (PRDB) with the RADB, the RADB has been populated with
RIPE-181-style Maintainer and AS Objects for all Autonomous Systems
known to the PRDB. NACRs are now being checked against this
information rather than the PRDB. In addition, the list of
contacts who are authorized to submit NACRs has been moved to the
RADB. The NACR contact data has long been queryable using the old
command:
whois -h prdb.merit.edu 'contact <AS_number>'
Now when you issue that command, you receive as output the RADB
Maintainer object that includes your contact information, along
with a message explaining how to update the Maintainer object. The
following new command is equivalent and produces the same output:
whois -h whois.ra.net 'MAINT-AS<AS_number>'
For AS690, you would type:
whois -h whois.ra.net MAINT-AS690
Similarly, network data has long been queryable using the old
command:
whois -h prdb.merit.edu '<net_number>'
Now when you issue that command, you receive as output the RADB
Route object that describes that network. The new, equivalent
command is:
whois -h whois.ra.net <net_number>
During the next phase of the PRDB --> RADB transition, the two
databases will run in parallel, and NACRs will be used as input to
both the PRDB and RADB. In the final phase, users will be able to
submit RIPE-style Route objects instead of NACRs. For further
information about the PRDB --> RADB transition, see

Jessica Yu of Merit has been working with ISI's Cengiz Alaettinoglu
to extend RIPE-181 to specify AS path expressions in routing
policies. Merit's Andy Adams and Alaettinoglu are modifying
RtConfig, a router configuration tool, to generate configuration
files supporting these extensions.
Merit has received a continuation of FAA funding for its joint
government/industry IDRP project, which is managed by the MITRE
Corporation. Merit's effort is led by Sue Hares, who co-chairs the
IETF Inter-Domain Routing Working Group. The project's Gated-IDRP
version 1.1, which supports advanced policy descriptions, is
expected to be released in April. In the next phase of the
project, Hares and other Merit staff will implement a mobile
Boundary Information System in IDRP.
Under a grant from NSF, Craig Labovitz continues development of the
Multi-Threaded Routing Toolkit (MRT), which provides a simple,
extensible platform for developing and debugging routing protocols
and routing code. The Toolkit comprises a set of generic libraries
that can be used to build small executables and scripts that
perform complex routing tasks quickly and efficiently. The MRT
architecture uses the multiple-thread technology available in the
Sun operating system to take full advantage of the speed and power
of multi-processor machines. For more information, contact
Labovitz at [email protected]

MIDNET
------
MIDNET INTRODUCES "A PRACTICAL GUIDE TO THE INTERNET" SEMINAR
MIDnet's first "Practical Guide to the Internet" seminar was held
during February.The goal of the seminar was to introduce newcomers
to the advantages of the Internet through real-world examples, and
to remove the mystic of the Internet by providing information in
layman's terms. The seminar was well attended, with an audience
that consisted of representatives from both the business and
educational communities.
Plans are currently underway to offer this seminar in additional
locations within the MIDnet region.
MIDNET MEMBER MEETING
During February, MIDnet representatives met with a state educators
to determine their Internet needs and goals. The meeting was
attended by representatives from K-12 as well as representatives
from institutes of higher education. MIDnet provided information on
the current state of its network in conjunction with the NSF
transition, and distributed a document which described and provided
pointers to Internet resources of particular interest to educators.
MIDNET'S INTERFACE TO POPULAR INTERNET RESOURCES
Activities are underway to expand the number of resources accessed
via MIDnet's WWW server. Resources currently enjoying popularity
include the Net-Happenings Mail List and Diane Kovac's Directory of
Scholarly Electronic Conferences, for which MIDnet provides a WWW
view with search and browse capabilities. MIDnet's NIC has
Cooper [Page 27]

identified two additional Internet resources which provide valuable
information to the Internet community. Agreements are currently
being drafted which will allow MIDnet to implement its interface to
these resources.

UCL
----
The major event of the last month was the setting up of a 4 nation
demonstration of IP Mbone based multimedia conferencing ofver the
PNO trial. The PNOs (Public Network Operators) of the EU (European
Union) have provided a trial 34Mbps ATM network for the current
year for research projects such as MICE. We configured a set of
mbone suns and Ciscos to use this between INRIA in france, the G7
summit meeting in Brussels, RUS in Germany and UCL in London. The
configuration has been reported elsewhere, and a detailed report on
the setup and performance will be available fairly soon. A draft is
available on request from [email protected], however, the
hypotheses we have formed about what worked and what didn't are not
completely proven yet.
Suffice it to say for now that it was a major success, using just
about every piece of networking technology anyone could think of.
The net ran uninterrupted (and unsupported) for 3 days, with only
the partial failure of an ATM/SMDS interworking unit dropping one
site off the demo about half way through.
There are some interesting lessons for how IP and Internet based
applications have to be configured to run this, and over the next 3
months, we shall be experimenting further to get a better
scientific confirmation of our hypotheses noted above.
Also, 2 papers were submitted to ACM SIGCOMM '95.
