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.
