Information technology - High-Performance Parallel Interface - Part 2: Framing Protocol (HIPPI-FP) ISO/IEC 11518-2:2000 ED2

Publication date:   Oct 25, 2000

Scope

This standard defines the data framing for an efficient simplex high-performance point-to-point interface. Characteristics of HIPPI-FP include: - large block data transfers with framing to split the data into smaller bursts; - separation of user control and data information, and early delivery of the control information; - identifiers for multiple upper-layer protocols (ULPs); - support for simplex topology; - support for ULP non-word-aligned and an arbitrary number of byte transfers; - error notifications, from the underlying physical layer, e.g., HIPPI-PH, are passed through this framing protocol to notify the upper layers of damaged data; - provides a connection-less data service; - best effort delivery of data, i.e., datagram; - connection control information, which may be used for physical layer switching, is supported. This part of ISO/IEC 11518 provides data framing for a high-performance point-to-point interface between data-processing equipment. The purpose is to facilitate the development and use of the HIPPI in computer systems by providing common data framing. It provides an efficient framing protocol for interconnections between computers, high-performance display systems, and high-performance, intelligent block-transfer peripherals.
