1 Introduction

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].

This protocol specification describes the communication that occurs between a compose desktop mediator and a surface manager proxy.

Sections 1.5, 1.8, 1.9, 2, and 3 of this specification are normative. All other sections and examples in this specification are informative.
