IP组播关键技术研究

Research on the Key Technology of IP Multicast

组播技术因为其独特的传输特性而成为当前网络应用的热点;通过介绍IP网络的数据传输方式和组播通信模型,给出了组播通信的优点,详细分析了IP组播体系的工作原理和关键技术,在此基础上,归纳出实现IP组播所涉及的技术要点,并提出了通过WinSock实现IP组播的基本步骤。

As the multicast technology has unique transmission performance, its application in network becomes one of the hotspots at present. By introducing the data transmission method and multicast communication model of IP network, this paper presents the merits of multicast communication, and analyzes the working principle and the key technology of IP multicast system. On the basis of that, the main technology in the application of IP multicast technology is concluded, and the basic steps to realize IP multicast technology based on WinSock is proposed.
