Critical Issues in High Bandwidth Networking
Status of this Memo
This memo presents the results of a working group on High Bandwidth Networking. This RFC is for your information and you are encouraged to comment on the issues presented. Distribution of this memo is unlimited.
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
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  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 .
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 lead one to believe that there will be available raw bandwidth approaching terabits per second.
The critical question to be addressed is how this raw bandwidth can be...
