Title (EN) USER-MODE BASED REMOTE DESKTOP PROTOCOL (RDP) ENCODING ARCHITECTURE
(FR) ARCHITECTURE DE CODAGE DE PROTOCOLE DE BUREAU À DISTANCE À BASE DE MODE UTILISATEUR
Abstract:
(EN) 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.
(FR) L'invention porte sur des techniques pour une architecture de codage de protocole de bureau à distance (RDP) à base de mode utilisateur. Une application de bureau en mode utilisateur et une application de canal virtuel en mode utilisateur sont exécutées dans un espace de session en mode utilisateur. Des données de canal virtuel provenant de l'application de canal virtuel subissent une conversion de paramètres et sont envoyées à un processus de codeur RDP dans un espace de système en mode utilisateur. Ici, elles sont converties en unités de données de protocole (PDU) RDP et envoyées à un client à distance à travers un réseau de communication. Des données graphiques provenant de l'application de bureau sont envoyées à un pilote d'affichage dans un espace de session en mode noyau puis un réflecteur graphique qui convertit les paramètres des données graphiques et les envoie au codeur RDP pour une transformation similaire.
