标准摘要
[中文适用范围]: 本文件通过服务和协议规定了 OSI 传输层和网络层。 它们可以被不同的应用程序使用。 传输层: ——将消息转换为单个数据包; ——在每个数据包中添加用于诊断和节点配置的协议控制信息; ——在每个数据包中添加用于诊断和节点配置的数据包标识符;以及 — 执行传输协议错误检测。 除了在较低层和较高 OSI 层之间映射服务接口参数之外,传输层协议不用于正常通信。 网络层: ——在每个网段中添加一个用于诊断和节点配置的节点地址;以及 — 观察每个网段的诊断和节点配置的时序。 除了在较低层和较高 OSI 层之间映射服务接口参数之外,网络层不用于正常通信。 [外文原描述]: This document specifies the OSI transport layer and network layer by means of services and protocols. They can be used by different applications. The transport layer: — transforms a message into a single packet; — adds protocol control information for diagnostic and node configuration into each packet; — adds packet identifier for diagnostic and node configuration into each packet; and — performs transport protocol error detection. The transport layer protocol is not used for normal communication except to map the service interface parameters between lower and upper OSI layers. The network layer: — adds a node address for diagnostic and node configuration into each segment; and — observes timing for diagnostic and node configuration of each segment. The network layer is not used for normal communication except to map the service interface parameters between lower and upper OSI layers.
