Speculative Remote Display (26119)

Speculative Remote Display is the only known solution that eliminates network round-trip time for remote display systems, making the system more responsive in a wide-area environment.

Remote display systems allow a distant user to control a computer or application with a graphical user interface. Increasingly, remote display systems are being used over wide-area networks where round trip latencies are inherently much higher than are those in local-area networks (Latencies also have far greater variance on WAN’s than on LAN’s). Speculative Remote Display eliminates network round-trip time for remote display systems by predicting the screen update events that the server will send and by applying them to the screen immediately. Incorrectly predicted events are undone when the actual events arrive from the server, with no net gain (or loss) in round-trip latency.

Details of Speculative Remote Display are described in S. Rossoff, and P. Dinda, Prospects for Speculative Remote Display, Technical Report NWU-EECS-06-08, Department of Electrical Engineering and Computer Science, Northwestern University, August, 2006

APPLICATIONS: Remote Display Systems

RESULTS: Surprisingly, even a very “naïve” predictor algorithm is able to correctly predict the next event 25-45% of the time.
