Abstract

The ANSI T11.1 task force has standardized HIPPI-6400 also known as Gigabyte System Network (GSN), a physical-level, point-to-point, full-duplex, link interface for reliable, flow-controlled, transmission of user data at 6400 Mbit/s, per direction. A parallel copper cable interface for distances of up to 40 m is specified in HIPPI-6400-PH [1]. Connections to a longer-distance optical interface are standardized in HIPPI-6400-OPT [3].

Abstract

The ANSI T11.1 task force has standardized HIPPI-6400 also known as

Gigabyte System Network (GSN), a physical-level, point-to-point,

full-duplex, link interface for reliable, flow-controlled,

transmission of user data at 6400 Mbit/s, per direction. A parallel

copper cable interface for distances of up to 40 m is specified in

HIPPI-6400-PH [1]. Connections to a longer-distance optical

interface are standardized in HIPPI-6400-OPT [3].

HIPPI-6400-PH [1] defines the encapsulation of IEEE 802.2 LLC PDUs

[10] and by implication, IP on GSN. Another T11.1 standard describes

the operation of HIPPI-6400 physical switches HIPPI-6400-SC [2].

T11.1 chose to leave HIPPI-6400 networking issues largely outside the

scope of their standards; this document specifies the use of HIPPI-

6400 switches as IP local area networks. This document further

specifies a method for resolving IP addresses to HIPPI-6400 hardware

addresses (HARP) and for emulating IP broadcast in a logical IP

subnet (LIS) as a direct extension of HARP. Furthermore it is the

goal of this memo to define a IP and HARP that will allow

interoperability for HIPPI-800 and HIPPI-6400 equipment both

broadcast and non-broadcast capable networks.
