Abstract
A system and method for scheduling the number of channels in video-on-demand servers so as to deal with time varying load. The scheduling process is hierarchical. A higher level scheduler controls the rate of channel consumption based on anticipated load, and a lower level scheduler selects the waiting client requests to be served when a channel is allocated by the higher level scheduler.
