Summary

Recommendation ITU-T X.603.1 | International Standard ISO/IEC 16512-2 describes the functions and procedures of the relayed multicast protocol part 2 (RMCP-2), which is an application-layer protocol constructing a one-to-many overlay multicast tree for multicast data delivery from one sender to multiple receivers over an IP-based network. The RMCP-2 consists of a multicast agent (MA) and a session manager (SM). The MA constructs the one-to-many relayed data path to provide multicast-based services. The SM controls and manages the RMCP-2 sessions. RMCP-2 can be used for applications that require one-to-many data delivery services, such as multimedia streaming services, file distribution services, e-learning, etc.

This Recommendation | International Standard also describes the security functionalities of RMCP-2. It provides various security facilities to fulfil general, as well as, specific security requirements. Some detailed functions that can operate with a variety of standardized security mechanisms are provided.
