Multicast Streaming

Applies To: Windows Server 2008

You can configure Multicast Streaming plug-ins in Windows Media Services to enable the multicast distribution of content. Multicast streaming is a one-to-many relationship between a Windows Media server and the clients receiving the stream. With a multicast stream, the server streams to a multicast IP address on the network, and all clients receive the same stream by subscribing to the IP address. Because there is only one stream from the server regardless of the number of clients receiving the stream, a multicast stream requires the same amount of bandwidth as a single unicast stream containing the same content. For more information, see Delivering content as a multicast stream.
