标准摘要
[中文适用范围]： 本推荐标准定义了数据链路层（帧、介质访问控制、数据服务和输入/输出[I/O]子层）。本文件规定了协议数据单元、帧、介质访问控制、快速和顺序控制的数据传输、计时服务、I/O控制以及在调用方和响应方之间建立和终止会话的程序。编码和同步子层的规范在题为《近程-1空间链路协议-编码和同步子层》的CCSDS推荐标准中另行规定（参考文献[5]）。物理层的定义在题为《近程-1空间链路协议-物理层》的CCSDS推荐标准中另行规定（参考文献[6]）。本推荐标准不包括：a)个别实现或产品；b)实际系统内服务接口的实现；c)执行程序所需的方法或技术；d)配置和控制协议所要求的管理活动。 [外文原描述]： ISO 22663:2015 defines the Data Link Layer (Framing, Medium Access Control, Data Services, and Input/Output [I/O] Sublayers). The specifications for the protocol data units, framing, media access control, expedited and sequenced-controlled data transfer, timing service, I/O control, and the procedures for establishing and terminating a session between a caller and responder are defined in this document. The Coding and Synchronization Sublayer is defined in the separate CCSDS Recommended Standard entitled, Proximity-1 Space Link Protocol?Coding and Synchronization Sublayer (reference [5]). The Physical Layer is defined in the separate CCSDS Recommended Standard entitled, Proximity-1 Space Link Protocol?Physical Layer (reference [6]). ISO 22663:2015 does not specify a) individual implementations or products, b) implementation of service interfaces within real systems, c) the methods or technologies required to perform the procedures, or d) the management activities required to configure and control the protocol.
