信息技术.增强通信传输协议:N工多点传送规范

[中文适用范围]： 此建议|国际标准规定了N-plex多播传输连接，其中所有参与者都是TS用户，其中之一是TC所有者。 N-plex 多播传输连接允许 TS 用户向所有组成员发送多播数据。 注意，只有当TS用户从TC-Owner获得令牌时，才允许它向组发送多播数据。 本规范描述了支持N-plex组播传输的协议，包括组播数据传输的连接管理（建立、终止、用户加入和离开）和可靠性控制机制。 [外文原描述]： ISO/IEC 14476-5:2008 defines a protocol for N-plex multicast transport over the Internet where IP multicast is supported. It provides the mechanisms of session control and error control. For session control, one participant is designated to manage creation/termination of a connection; join/leave of a participant; and tokens which allow the specific participants to send data. For error control, it provides the mechanisms of tree-based loss recovery; control tree construction with two-layer logical tree; and logical tree adaptation with packet delivery status. ISO/IEC 14476-5:2008 specifies the protocol details such as packet format, procedures, and parameter values. This protocol can be used for the applications which require many-to-many reliable data delivery service.
