Abstract
Techniques are disclosed for a user-mode based remote desktop protocol (RDP) encoding architecture. A user mode desktop application and user mode virtual channel application run in user-mode session space. Virtual channel data from the virtual channel application is marshaled and sent to a RDP encoder process in user-mode system space. There it is converted to RDP protocol data units (PDU) and sent to a remote client across a communications network. Graphics data from the desktop application is sent to a display driver in kernel-mode session space and then to a graphics reflector that marshals the graphics data and sends it to the RDP encoder for a similar transformation.
