ABSTRACT

At the request of Maj. Mark Pullen and Maj. Brian Boesch of DARPA, an

ad-hoc working group was assembled to develop a set of

recommendations on the research required to achieve a ubiquitous

high-bandwidth network as discussed in the FCCSET recommendations for

Phase III.

This report outlines a set of research topics aimed at providing the

technology base for an interconnected set of networks that can

provide highbandwidth capabilities. The suggested research focus

draws upon ongoing research and augments it with basic and applied

components. The major activities are the development and

demonstration of a gigabit backbone network, the development and

demonstration of an interconnected set of networks with gigabit

throughput and appropriate management techniques, and the development

and demonstration of the required overall architecture that allows

users to gain access to such high bandwidth.

1. Introduction and Summary

1.1. Background

The computer communications world is evolving toward both high-

bandwidth capability and high-bandwidth requirements. The recent

workshop conducted under the auspices of the FCCSET Committee on High

Performance Computing [1] identified a number of areas where

extremely high-bandwidth networking is required to support the

scientific research community. These areas range from remote

graphical visualization of supercomputer results through the movement

of high rate sensor data from space to the ground-based scientific

investigator. Similar requirements exist for other applications,

such as military command and control (C2) where there is a need to

quickly access and act on data obtained from real-time sensors. The

workshop identified requirements for switched high-bandwidth service

in excess of 300 Mbit/s to a single user, and the need to support

service in the range of a Mbit/s on a low-duty-cycle basis to

millions of researchers. When added to the needs of the military and

commercial users, the aggregate requirement for communications

service adds up to many billions of bits per second. The results of

this workshop were incorporated into a report by the FCCSET [2].

Fortunately, technology is also moving rapidly. Even today, the

installed base of fiber optics communications allows us to consider

aggregate bandwidths in the range of Gbit/s and beyond to limited

geographical regions. Estimates arrived at in the workshop...
