Abstract (Summary)

The described Specification provides an encapsulation of ISO/IEC 8802-2 (IEEE Std 802.2) Logical Link
Control Protocol Data Units over the High-Performance Parallel Interface (HIPPI).

Characteristics of HIPPI-LE include:

Encapsulation of arbitrary Protocol Data Units that conform to ISO/IEC 8802-2 (IEEE Std 802.2) Logical
Link Control;

Provision for 48-bit source and destination addresses conforming to IEEE 802.1A;

Provision for eight forwarding classes to distinguish, for example, among ordinary data PDUs, PDUs for
services that require bandwidth guarantees such as packet video, etc.
 

Audience

Purchasing users: can require conformance to the standard in order to insure interoperability between driver
software implementations to obtain maximum portability and system independence.

System and Adapter Vendors: can build systems using HIPPI-LE to provide interoperable data movement.
 

Scope (Intention)

HIPPI-LE is intended to allow all HIPPI systems to interoperate among themselves and with other physical
media when using any protocols compatible with ISO/IEC 8802-2.  (including the Internet family of protocols)
 

Key Words

Internet Protocol (IP)

Protocol Data Unit (PDU)

Link Encapsulation (LE)
 

Conformance

Conformance is defined by adhering to the HIPPI-LE Standard.

The HIPPI-LE Standard does not provide tests for conformance.
