摘要：
A random early migration (REM) scheme is proposed to handle the request migration in a video-on-demand (VoD) server system. When a new request is dispatched to a media server, REM compares the current service load with thresholds and decides whether request migration is needed with a certain probability, which is a function of the service load. We also present an initial video copy allocation algorithm to increase the connectivity degree among video servers to achieve the static load balance. Simulation results demonstrate that REM can achieve an enhanced performance for the VOD system in terms of the service failure rate and the migration cost.
