标准摘要
[中文适用范围]： ISO/IEC 11518 的这一部分指定了使用高性能并行接口 (HIPPI)（数据处理设备之间的高性能点对点接口）对物理层交换机的控制。 ISO/IEC 11518 的这一部分不能防止互连多个 HIPPI-PH 的中间设备引入的错误。 ISO/IEC 11518 这一部分的目的是通过提供通用的物理开关控制来促进 HIPPI 在计算机系统中的开发和使用。 它为互连计算机、高性能显示系统和高性能智能块传输外设的物理层交换机提供交换机控制结构。 ISO/IEC 11518 的这一部分也适用于点对点 HIPPI 拓扑。 [外文原描述]： This part of ISO/IEC 11518 defines the control for HIPPI physical layer switches. HIPPI by itself is an efficient simplex high-performance point-to-point interface. The physical switch control allows the interconnection of multiple HIPPI based equipments with HIPPI physical layer switches. Characteristics of this HIPPI physical switch control protocol include: - support for both source routing and destination addresses; - I-Fields and CCIs can span multiple physical layer switches within a fabric; - when a Destination end-point receives a packet, it can easily manipulate the I-Field received to return a reply packet to the Source; - support for physical layer switches with differing numbers of ports, all within the same fabric; - specified reserved addresses to aid address self-discovery, switch management, and switch control. The purpose of this part of ISO/IEC 11518 is to facilitate the development and use of the HIPPI in computer systems by providing common physical switch control. It provides switch control structures for physical layer switches interconnecting computers, high-performance display systems, and high-performance, intelligent block-transfer peripherals. This part of ISO/IEC 11518 also applies to point-to-point HIPPI topologies.
