RFC 1983:

An emerging ANSI standard which extends the computer bus over fairly short distances at speeds of 800 and 1600 Mb/s. HIPPI is often used in a computer room to connect a supercomputer to routers, frame buffers, mass-storage peripherals, and other computers.

RFC 2067:

ANSI Standard X3.218-1993 defines the encapsulation of IEEE 802.2 LLC PDUs and, by implication, IP on HIPPI.

ANSI X3.222-1993 describes the operation of HIPPI physical switches.

RFC 2834:

The ANSI High-Performance Parallel Interface (HIPPI) is a dual simplex data channel. HIPPI can send and receive data simultaneously at 800 or 1600 megabits per second. Between 1987 and 1997, the ANSI X3T11.1 HIPPI working group (now known as NCITS T11.1) standardized five documents that bear on the use of HIPPI as a network interface. They cover the physical and electrical specification, the framing of a stream of bytes, encapsulation of IEEE 802.2 LLC, the behavior of a physical layer switch and the physical- level and optical specification. HIPPI-LE also implies the encapsulation of Internet Protocol.


(RFC 2834) A combination and adaptation of the Internet Address Resolution Protocol (ARP) and Inverse ARP protocols. HARP also describes the HIPPI specific version of ARP (i.e. the protocol and the HIPPI specific encoding).

(RFC 2834) An implementation of HIPPI in serial fashion on coaxial cable or optical fiber.

HRAL, HARP Request Address List.
(RFC 2834) A list of ULAs to which HARP messages are sent when resolving names to addresses.

PIBES, Protocol for Internet Broadcast Emulation Server.

Switch Address.
(RFC 2834) A value used as the address of a port on a HIPPI-SC network. It is transmitted in the I-field. HIPPI-SC switches map Switch Addresses to physical switch port numbers. The switch address is extended with a mode byte to form an I-Field

ULA, Universal LAN MAC Address.
(RFC 2834) A 48-bit globally unique address, administered by the IEEE, assigned to each port on an Ethernet, FDDI, 802 network, or HIPPI-SC LAN.



[RFC 2067] IP over HIPPI.

[RFC 2834] ARP and IP Broadcast over HIPPI-800.

[RFC 2835] IP and ARP over HIPPI-6400 (GSN).


Obsolete RFCs:
