摘要
随着多媒体视频会议系统的迅速发展,会议系统中基于IP网络流媒体的传输技术,特别是音、视频数据的多点传输,成为系统服务质量的重要问题。本文结合会议系统和流媒体传输的技术及特点,对多媒体会议系统中音、视频数据传输的组播问题加以研究并针对大型网络中的PIM-SM提出一种改进方式。
As a method of streaming transmission technology, multicast could transmit data on network effectively. This technology could reduce the network congestion, enhance the performance of the network. This paper talked about the evolution of multimedia conference system, introduced the IP Multicast protocol, addressing of multicast, and the transmission and reception of multicast IP datagram, put forward a method to improve on PIM-SM (one of multicast routing protocol).
