Microsoft Media Services

From Wikipedia, the free encyclopedia

Microsoft's streaming server Microsoft Media Services (also called NetShow Services) uses the Microsoft Media Server (MMS) protocol to transfer unicast data. MMS can be transported via UDP or TCP. If the Windows Media Player client cannot negotiate a good connection using MMS over UDP, it will resort to MMS over TCP. If that fails, the connection can be made using a modified version of HTTP (always over TCP). This is not as ideal for streaming as MMS over UDP, but ensures connectivity nonetheless.

The default port for MMS is 1755.
