摘要
网络音视频会议中的IP组播技术大大减轻了骨干网的网络流量,提高了会议质量。研究IP组播技术有助于更好地保障网络音视频会议,本文深入研究了IP组播技术中常用的二层组播协议IGMP SNOOPING、三层组播协议IGMP和PIM-SM,并对PIM-SM协议中的数据转发机制做了深入研究。
The IP multicast technology in the network audio and video conference greatly reduces the network flows of the backbone network,and improves the quality of the conference.Research on IP multicast technology is helpful to better guarantee network audio and video conference.This article deeply researches the commonly used two-layer multicast protocol IGMP SNOOPING,three-layer multicast protocol IGMP and PIM-SM in IP multicast technology,and deeply investigates the data forwarding mechanism in the PIM-SM protocol.
