信息技术.转接多路广播控制协议(RMCP).框架

[中文适用范围]： 本部分条款适用于实现中继多播的中继多播控制协议（RMCP）。本部分规定了RMCP的框架，并定义了其概念、体系结构、消息格式、安全考虑以及其他实现所需的组件。 [外文原描述]： Relayed multicast protocol (RMCP) is a protocol which is used to realize a relayed multicast data transport scheme. Different from the conventional IP multicast, RMCP can configure a relayed multicast path that multicast traffic flows by using intermediate end-hosts. RMCP can be applied to the current unicast based IP network where IP multicast is not fully deployed. ISO/IEC 16512-1:2016 addresses the basic concepts needed to specify RMCP for relayed multicast. It defines the related terminology and proposes a framework for the future development of subsequent protocols. The framework covers network topology including network entities and the relationship among them, service scenarios, basic operations, and message format.
