Welcome to the FTP archives of the ANSI X3T11 HIPPI committee.

HIPPI (HIgh Performance Parallel Interface) is a switchable data
channel operating at either 800 or 1600 Megabits per second.  It is
suitable for the connection of high speed peripherals to one or many host
computers and the construction of multi-gigabit local computer
networks.

HIPPI has been in the standardization process for some years and 
the technical aspects of all specifications are considered complete.

The documents in this archive are all in PostScript form, and should
be printable on a wide variety of PostScript printers.

HIPPI SPECIFICATIONS

The formal HIPPI specifications are as follows:

hippi-ph_8.2.ps
	Contains the electrical, signalling, and connector specifications
	for HIPPI.  HIPPI-PH is an approved American National Standard;
	This is a maintenance copy consistent with the standard, and 
	includes a list of proposed changes for future editions. 

hippi-fp_4.4.ps
	Specifies the basic header and message framing rules that are 
	used to transfer packets of information between HIPPI nodes. 
	HIPPI-FP is an approved American National Standard;
	This is a maintenance copy consistent with the standard, and 
	includes a list of proposed changes for future editions. 
	There is a draft amendment for HIPPI-FP called hippi-fp_amend.a.ps
	(the amendment material is already included in hippi-fp_4.4.ps)

hippi-le_3.4.ps
	Specifies the encapsulation of IEEE 802.2 messages on HIPPI-FP
	headers.

hippi-sc_2.7.ps
	Specifies the addressing and conventions used to connect to a
	variety of remote nodes through one or more HIPPI switches.

hippi-atm_0.2.ps
	Specifies a mapping of HIPPI to HIPPI over ATM and also 
	discusses the requirements to seamlessly convert IP over 
	HIPPI to IP over ATM.

hippi-ipi_0194.ps
	Is the annex to the IPI3 documents that describes the IPI3 command
	mapping on HIPPI.

OTHER DOCUMENTS OF INTEREST

A variety of other documents are here for reference:

serial_hippi_1.0.ps
	Contains a specification for transport of HIPPI signals over a
	pair of single mode optical fibers. Serial HIPPI *will not*
	be an American National Standard; it is an ad hoc development
	which has been implemented in silicon and used by a variety of
	HIPPI manufacturers.

hippi-mi_2.6.ps
	Contains a specification for the now defunct HIPPI-MI protocol
	to perform direct memory accesses to and from nodes on a HIPPI
	network. Various groups are using HIPPI-MI conventions for
	private protocols; the document is worth examination by those
	interested in channel connected front end processors.

rfc1374.txt
	A copy of the RFC1374 document for the transport of IP datagrams
	and ARP messages over HIPPI. This is identical to the RFC stored 
	at archive sites elsewhere and is provided here for convenience.

draft-miller-hippimib-01.ps
	A draft document specifying an SNMP Management Information Base
	for HIPPI end node interfaces.


WANT MORE INFORMATION ON HIPPI?

HIPPI is a proven standard which continues to have no rival for the 
transfer of data between computers and peripherals at truly high 
speeds. It owes much of its performance to the simplicity of its
protocols, which has also made it inexpensive to implement in both
silicon, interfaces, and host software.
