摘要
组播技术是一种针对点对点或多点对多点的数据传输的组通信模型,是适应未来网络发展的重要支撑技术。虽然组播技术的应用明显地提高了网络利用率,但组播网络本身存在的拥塞问题和组播路由协议在其扩展性和公平性方面存在固有的问题,严重阻碍组播技术的广泛应用。文中对组播进行了简单介绍,并着重针对组播拥塞控制技术及组播的各种路由协议应用分别进行了对比,指出了各种算法及协议本身存在的优缺点,并指出了组播技术的研究方向。
Multicast technology is a group communication model of point- to - point or multipoint - to - multipoint data transmission, which is also an important supporting technology to adapt to the development of the future network. Although the application of multicast technology significantly improves the utilization ration of the network, the multicast networks exist the congestion problems in itself and multicast protocols exist the inherent problems in its scalability and fairness are seriously obstruct the wider application of the multicast technology. In this paper,introduce the multicast technology, then focus on the comparison of the multicast congestion control technology and the application of many existing multicast routing protocol respectively, and in the last,point out the further research trend of the multicast.
