1.4 Relationship to Other Protocols
The qWave Protocol is one in a suite of protocols specific to the Quality Windows Audio/Video Experience feature in Windows Vista operating system and Windows 7 operating system qWave provides services (such as QoS) revolving around the streaming of multimedia and real-time content over variable bandwidth networks. For an example of such a service, see [MSDN-QWAVE].
qWave is DLNA-compliant in that it uses Wi-Fi Multimedia (WMM®) rules to prioritize packets over 802.11 and 802.3 media.
The qWave Protocol operates directly over the TCP/IP and UDP/IP protocols. It is a stand-alone protocol.
qWave Protocol shares the same Handshake Header message format as the qWave-WD Protocol (see [MS-QDP]). A device that implements the qWave Protocol can also implement the qWave-WD Protocol, both of which will listen on the same TCP/IP port. In that case, the Proto_and_Msg_ID field in the Handshake Header has to be used to disambiguate the purpose of all TCP/IP connections accepted on the common port.
