信息技术 高性能并行接口 第2部分:组帧协议(HIPPI-FP)

[中文适用范围]： ISO/IEC 11518 的这一部分为数据处理设备之间的高性能点对点接口提供数据帧。 ISO/IEC 11518 的这一部分不能防止互连多个 HIPPI-PH 的中间设备可能引入的某些错误。 ISO/IEC 11518 这一部分的目的是通过提供通用数据框架来促进 HIPPI 在计算机系统中的开发和使用。 它为计算机、高性能显示系统和高性能智能块传输外设之间的互连提供了高效的成帧协议。 [外文原描述]： 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.
