标准摘要
[中文适用范围]: ISO/IEC 11518 的这一部分规定了物理层、点对点、全双工链路接口,用于以每个方向 6 400 Mbrt/s 的速度可靠地、受流量控制地传输用户数据,传输距离可达 1公里。 指定距离最长为 40 m 的并行铜缆接口。 提供与单独的长距离光学接口的连接。 小型固定大小的微数据包为小型传输提供了高效、低延迟的结构,并为大型传输提供了组件。 规范包括: ——自动重传以纠正有缺陷的数据; ——称为微数据包的小型数据传输单元的格式; ——消息结构,包括网络应用的路由信息; ——端到端以及链路到链路、校验和; ——并行信号的时序要求; ——使用铜同轴电缆的并行接口; ——连接到单独的本地光纤接口; ——链路级协议调整为最大距离 1 公里。 [外文原描述]: Specifies a physical-level, point-to-point, full-duplex, link interface for reliable, flow-controlled transmission of user data at 6 400 Mbit/s per direction, across distances of up to 1 km. Characteristics of a HIPPI-6400-PH physical-layer interface include: - user data transfer bandwidth of 6 400 Mbit/s (800 MByte/s); - a full-duplex link capable of independent full-bandwidth transfers in both directions simultaneously; - four virtual circuits providing a limited multiplexing capability; - a fixed-size transfer unit, i.e., a 32-byte micropacket, for hardware efficiency; - a small transfer unit resulting in low latency for short Messages, and a component for large transfers; - credit-based flow control that prevents buffer overflow; - end-to-end, as well as link-to-link, checksums; - automatic retransmission to correct flawed data providing guaranteed, in-order, reliable, data delivery; - an a.c. coupled parallel electrical interface for driving parallel copper cable over limited distances; - a parallel electrical interface for driving a local optical interface for longer distances.
