The goal of the workshop was to gather together a small number of
leading researchers on high-speed networks in an environment
conducive to lively thinking. The hope is that by having such a
workshop the IRSG has helped to stimulate new or improved research in
the area of high-speed networks.
Attendance at the workshop was limited to fifty people, and attendees
had to apply to get in. Applications were reviewed by a program
committee, which accepted about half of them. A few key individuals
were invited directly by the program committee, without application.
The workshop was organized by Dave Clark and Craig Partridge.
This workshop report is derived from session writeups by each of the
session chairman, which were then reviewed by the workshop
Session 1: Protocol Implementation (David D. Clark, Chair)
This session was concerned with what changes might be required in
protocols in order to achieve very high-speed operation.
The session was introduced by David Clark (MIT LCS), who claimed that
existing protocols would be sufficient to go at a gigabit per second,
if that were the only goal. In fact, proposals for high-speed
networks usually include other requirements as well, such as going
long distances, supporting many users, supporting new services such
as reserved bandwidth, and so on. Only by examining the detailed
requirements can one understand and compare various proposals for
protocols. A variety of techniques have been proposed to permit
protocols to operate at high speeds, ranging from clever
implementation to complete relayering of function. Clark asserted
that currently even the basic problem to be solved is not clear, let
alone the proper approach to the solution.
Mats Bjorkman (Uppsala University) described a project that involved
the use of an outboard protocol processor to support high-speed
operation. He asserted that his approach would permit accelerated
processing of steady-state sequences of packets. Van Jacobson (LBL)
reported results that suggest that existing protocols can operate at
high speeds without the need for outboard processors. He also argued
that resource reservation can be integrated into a connectionless
protocol such as IP without losing the essence of the connectionless
architecture. This is in contrast to a mor...
