The Remote Desktop Protocol: Desktop Composition Virtual Channel Extension enables a remote display client to replicate the functionality of the Desktop Window Manager (DWM)[MSDN-DWM] across a network boundary. The actual composition of the desktop and the protocol governing it are specified in [MS-RDPBCGR] and [MS-RDPEGDI]. This composition is driven by the Remote Desktop Protocol: Composited Remoting 2 protocol [MS-RDPCR2].
