1. Introduction

As the capacity of local area networks increases to meet the demands

of high volume application data, there is a class of network

intensive problems which may be applied to small clusters of

workstations with high bandwidth interconnection.

A general observation of networks is that the bit rate of the data

path typically decreases as the distance between hosts increases. It

is common to see regional networks connected at a rate of 64Kbps and

office networks connected at 100Mbps, but the inverse is far less

common.

The same is true of peripheral and memory interconnection. Memory

close to a CPU's core may run at speeds equivalent to a gigabit

network. More importantly, devices such as disks may connect a

number of metres away from its host at speeds well in excess of

current local area network capacity.

This document outlines a protocol for connecting hosts running the

TCP/IP protocol suite over a Small Computer System Interface (SCSI)

bus. Despite the limitation in the furthest distance between hosts,

SCSI permits close clusters of workstations to communicate between

each other at speeds approaching 360 megabits per second.

The proposed introduction of newer SCSI implementations such as

serial SCSI will bring much faster communication at greater

distances.
