Introduction

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

participants.

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...
