标准范围

指定物理级别、点对点、全双工、链路接口以每方向6400 Mbit/s的速度，跨距离可达1公里。HIPPI-6400-PH物理层界面的特征包括:-用户数据传输带宽为6400 Mbit/s（800 MByte/s）；-一种全双工链路，能够在两个方向上进行独立的全带宽传输同时-提供有限复用能力的四个虚拟电路；-固定大小的传输单元，即32字节的微包，用于提高硬件效率；-一个小型传输单元，可降低短消息的延迟，以及一个用于大额转账；-基于信用的流量控制，防止缓冲区溢出；-端到端以及链接到链接的校验和；-自动重新传输以纠正有缺陷的数据，提供有保证的-秩序，可靠，数据传递；-一种交流耦合的并联电气接口，用于在有限空间内驱动并联铜缆距离；-一种并行电气接口，用于驱动本地光学接口进行更长距离的传输。

Specifies a physical-level, point-to-point, full-duplex, link interfacefor reliable, flow-controlled transmission of user data at 6 400 Mbit/s per direction, acrossdistances 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 directionssimultaneously;- 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 forlarge 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 limiteddistances;- a parallel electrical interface for driving a local optical interface for longer distances.
