Overview

ISO/IEC 11518-3:1996 (HIPPI-LE) specifies how to encapsulate ISO/IEC 8802-2 (IEEE 802.2) Logical Link Control (LLC) Protocol Data Units (PDUs) for transport over the High-Performance Parallel Interface (HIPPI). The standard defines the HIPPI‑LE PDU format, the interface and service primitives between HIPPI‑LE and higher‑layer LLC, and the mechanisms needed to forward 48‑bit MAC-style addresses and resolve those addresses to HIPPI switch addresses.

Key Topics

Encapsulation of IEEE 802.2 LLC PDUs: Defines how arbitrary ISO/IEC 8802-2 LLC PDUs are packaged into HIPPI‑LE PDUs (LE Header + D2 area) for transmission over HIPPI.

PDU and data formats: HIPPI‑LE header and D2 data area formatting rules (see clause 6). The document notes mapping of 6‑byte ISO/IEC 8802‑2 MAC addresses into HIPPI words.

Service primitives: Four primitive types-Request, Confirm, Indicate, Response-and specific HIPPI‑LE primitives (e.g., LE‑TRANSFER, LE‑ADDRESS‑RESOLUTION, LESM status/control) used to integrate LLC and station management with HIPPI services.

Addressing and resolution: Support for ISO/IEC 8802‑2 48‑bit source/destination addresses and an address resolution mechanism to map higher‑level addresses to HIPPI switch addresses. HIPPI‑SC defines switch address formats (Logical Address - 12 bits; Source Route - 24 bits).

Forwarding classes: Provision for eight forwarding classes to distinguish QoS or service types (e.g., bulk data vs. bandwidth‑sensitive streams).

Interaction with HIPPI‑FP: HIPPI‑LE uses HIPPI Framing Protocol (HIPPI‑FP) services for lower‑level transfer; implementers must consider D2‑Offset effects on performance.

Applications and Users

This standard is relevant for:

Network and systems engineers integrating HIPPI interconnects with IEEE 802.2 LLC‑based protocols.

Hardware and firmware developers building HIPPI NICs, switches, or framing protocol (HIPPI‑FP) interfaces.

HPC and storage system architects working with legacy or specialized high‑bandwidth interconnects that require robust encapsulation of LAN/MAC‑style traffic.

Vendors implementing station management (SMT) and address resolution services on HIPPI fabrics.

Practical uses include transporting LAN/LLC PDUs across point‑to‑point or switched HIPPI links in environments requiring high throughput and deterministic forwarding behavior.
