信息技术.增强通信传输协议:单工多点传送规范

[中文适用范围]： 此建议|国际标准指定了增强型通信传输协议 (ECTP)，该协议是一种传输协议，旨在支持支持多播功能的 IP 网络上的互联网多播应用。 此建议|国际标准指定了由一个发送方和多个接收方组成的单工多播传输连接的 ECTP。 此建议|国际标准规定了以下协议操作的协议过程： a) 连接创建和树创建； b) 组播数据传输； c) 基于树的可靠性控制，具有错误检测、重传请求和重传； d) 迟到和迟退； e) 树成员资格维护； f) 连接终止。 [外文原描述]： This Recommendation | International Standard specifies the Enhanced Communications Transport Protocol (ECTP), which is a transport protocol designed to support Internet multicast applications over multicast-capable IP networks. This Recommendation | International Standard specifies the ECTP for the simplex multicast transport connection that consists of one sender and many receivers. This Recommendation | International Standard specifies the protocol procedures for the following protocol operations: a) connection creation with tree creation; b) multicast data transmission; c) tree-based reliability control with error detection, retransmission request and retransmission; d) late join and leave; e) tree membership maintenance; and f) connection termination.
