Method and system for efficiently reducing graphical display data for transmission over a low bandwidth transport protocol mechanism

摘要

The present invention improves the performance of distributed systems by reducing the amount of graphical data transmitted between an application server and a thin client. The invention provides a method and apparatus for remotely controlling, by a server, the formation of an off-screen surface at a client coupled to the server via a communications network, the method being performed at the server and comprising the steps of: instructing the client to select a first memory region for allocation to the off-screen surface, the first memory region corresponding to a memory coupled to the client; transmitting indicia of a graphical data to the client; and instructing the client to copy the graphical data associated with the indicia to a particular location within the first memory region.
