采用P2P的技术建立流媒体广播，可以很大程度节省服务器的带宽消耗。先建立一个流媒体服务器，可以采用WINDOWS2003自带的media server，生成一个信号源。P2P流媒体广播的服务端从流媒体服务器提取一个流作为源，这个源必须是用http协议来提取的，然后再由P2P服务端分发到各个P2P客户端.服务端与客户端的例子程序-using the technology to establish peer-to-peer streaming media broadcasts, can save a large extent server bandwidth consumption. First establish a streaming media server, we can use the media WINDOWS2003 own server, generating a signal source. P2P streaming media broadcasting services from streaming-media server extraction flow as a source, the source must be used to extract http protocol, then peer-to-peer server distributed to various peer-to-peer client.
