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.

This document is now a Proposed Standard Protocol.  

This document specifies an Internet standards track protocol for
the Internet community, and requests discussion and suggestions
for improvements.  Please refer to the current edition of the
"Internet Official Protocol Standards" (STD 1) for the
standardization state and status of this protocol.  Distribution
of this memo is unlimited.
