本标准定义了高效单工高性能点对点接口的数据帧。HIPPI-FP的特点包括: -大数据块数据传输，采用分帧方式将数据分割成较小的突发； -将用户控制和数据信息分离，并提前交付控制信息； -多个上层协议（ULP）的标识符； -支持单纯形拓扑； -支持ULP非字对齐和任意数量的字节传输； -来自底层物理层（例如HIPPI-PH）的错误通知通过该帧协议传递，以通知上层损坏的数据； -提供无连接数据服务； -尽最大努力交付数据，即数据报； -支持可用于物理层交换的连接控制信息。 ISO/IEC 11518的这一部分提供了高性能的数据帧- 性能数据处理设备之间的点对点接口。其目的是通过提供通用数据框架，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围设备之间的互连提供了高效的帧协议。

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.
