Windows Media Porting Kits: Other Windows Media Technologies
July 2010

Windows Media Networking Protocols Porting Kit

The Windows Media Networking Protocols Porting Kit is no longer available. The specifications for these protocols are available for download as outlined below.

Technical Specification

The Windows Media Networking Protocols Technical Specification contains the following:
  • MS-WMSP: Windows Media HTTP Streaming Protocol
    This specification defines a Microsoft proprietary protocol referred to as the Windows Media HTTP Streaming Protocol. The Windows Media HTTP Streaming Protocol is a client/server–based protocol used to stream real-time data between the client (the receiver of streaming data) and server (the sender of streaming data).
  • MS-RTSP: Real Time Streaming Protocol (RTSP): Windows Media Extensions
    This document defines Windows Media extensions to the Real-Time Streaming Protocol (RTSP), as specified in [RFC2326]. RTSP streams multimedia from Windows Media Services to Windows Media Player or other instances of Windows Media Services. RTSP Windows Media Extensions use TCP and the User Datagram Protocol (UDP).
  • MS-MSB: Media Stream Broadcast (MSB) Protocol
    The Media Stream Broadcast (MSB) Protocol is a Microsoft proprietary protocol that allows distribution of Advanced Systems Format (ASF) packets over a network for which Internet Protocol (IP) multicast is enabled.
  • MS-MSBD: Media Stream Broadcast Distribution (MSBD) protocol
    The Media Stream Broadcast Distribution (MSBD) Protocol is a Microsoft proprietary protocol that is used for transferring an audio-visual content stream from a server to a single client or multiple clients.
  • MS-MMSP: Microsoft Media Server (MMS) Protocol
    This specification defines a Microsoft proprietary protocol referred to as the Microsoft Media Server (MMS) Protocol. MMS streams multimedia from Windows Media Services to Windows Media Player, or to another instance of Windows Media Services. MMS uses TCP and the User Datagram Protocol (UDP).
  • MS-WMLOG: Windows Media Log Data Structure
    This specification defines the Windows Media Log Data Structure, a Microsoft proprietary interface. The Windows Media Log Data Structure is syntax for logging messages. The logging messages specify information about how a client received multimedia content from a streaming server. For example, logging messages can specify how many packets were received and how long it took for the client to receive the content.

Technical Specification Delivery

Delivery and control of the Networking Protocols Technical Specification is managed across Microsoft by the Microsoft Communications Protocol Program (MCPP). This program makes available, on reasonable and non-discriminatory terms, the communications protocols implemented in a Microsoft Windows 2000 Professional, Windows XP, or successor desktop operating system that are used to interoperate or communicate natively with a Microsoft server operating system product. More than 80 proprietary protocols that were not previously available are now available for license by third parties.

The Microsoft Communications Protocol Program (MCPP) technical documentation is now available on this MSDN Web site.
