To avoid redundant transmissions of identical command sequences that are generated by the application a transparent stream cache can be used that accelerates the multicast communication channel. It can be profiled that applications that do not use display lists or VBO s to control the rendering put a heavy load on the client host because the cache control has to compute a checksum for the identification of repeated command sequences. In this paper we analyse the possibilities to improve the stream caching for unmodified GL applications. As our main result we introduce a new GL extension to control the stream cache with minimally modified applications.Categories and Subject Descriptors (ACM CCS): I.3.2 [Computer Graphics]: Distributed/network graphics
