Deterministic Load Balancing Technique for VBR Video Server

Abstract

For a video on demand (VOD) system we propose a scheme that adjusts begin of service time of user's requests and dynamically balances the load of the bandwidths on disks to achieving higher video throughput.Using round-based policy, the disks fill the buffer memory with data for each user per round. We consider the retrival of variable bit rate (VBR) video data from the disks in the server subject to the constrains that the disk bandwidth and buffer memory between server's disk and network subsystem. We find that our load balancing policies let a significant additional amount of throughput over both Constant Time Length (CTL) and Constant Data Length (CDL) round-based policies[1].
