Minutes of BT MMN Technical Meeting at Loughborough University 7/9/95

Morning session was spent presenting the work of each University.

WP1. Imperial presented their work on configuration management,
multimedia communications classes and how their work was CORBA
compliant. Various problems with Orbix were mentioned.

WP2. UCL presented a summary of their recent report on policy based
connection management system, discussing the objectives of the system
and describing the components which are being developed.

WP3. Lancaster presented a description of the work being done on End
system QoS management. This included a description of Andrew Campbell's
work with Columbia University in Project xbind, and a summary of their
current work on QoS mechanisms for heterogeneous multiservice networks
and End system QoS management on ATM networks.

WP4. LUT presented their work on Traffic monitoring and Measurement.
Their dedicated SMDS monitoring system had been deployed. A WWW
form/CGI script has been written to display results. Various graphs of the
SMDS monitoring were presented, followed by a summary of their work
plans for the next two years.

WP5. Cambridge presented their work on Security. They have written a
document on the underlying assumptions for their security architecture and
devised an approach using AnsaWare and the security service GSS API.
They are currenty desiging a trial implementation to test the assumptions
and will do a trial implementation; they will focus on the performance of
security mechanisms, particularly on the cost of authentication calls.

WP6. Oxford Brookes presented their simulation work that examines how
use of a Dynamic Bandwidth controller for ATM ABR traffic can improve link
utilisation in switches. OBU and BT have developed two models, one in
Simula, the other in BoNes and similar results have been obtained. In the
future, they plan to try out various bandwidth allocation algorithms.

Action: The slides from all the presentations would be sent to UCL and
added to the project's WWW server.

John Adams and Jon Crowcroft pointed out the linkages between various
work packages and the meeting decided to break into three groups for the
afternoon session:

1. One group edited the work plan for years 2 and 3. [Ed's note: no minutes
for this discussion].

Actions: Jon Crowcroft would draw together the changes and send them off
to the list and BT ready for next week's management meeting; a list of
deliverables for year 1 needs to be drawn up and sent to BT.

2. Another group discussed network monitoring and the overlaps between
OBU, Loughborough and UCL. The group would have an email discussion
for the next 2 months; we would then meet with an aim to draw something
out of the discusions - e.g. a report about discussion, possibly a paper,
and/or a small experiment.

Action: Loughborough to set up the email list

3. Another group discussed the relationship between IC's policy language
work and Lancaster's QoS work and Cambridge security work. IC would
liaise with both: with Lancaster about the incorporation of negotiation of QoS
in a heterogeneous network into the policy language; with Cambridge about
the relationship between IC's domains model and Cambridge's security
(encryption) mechanisms. [minutes from Paul Wernick]

Interactions with other organisations.  David Hutchinson reported that he had
attended an ESPRC strategy meeting where problems with SuperJanet were
raised.

Meeting ended at 3.45
