Abstract
As IPTV services advance, an increasing user demand and tremendous content volume of multimedia content cause some difficulties in network resource management. In this paper, we propose an improved load balancing algorithm for VoD service. Unlike existing algorithms, the proposed algorithm considers users’ behaviors for VoD service, and determines the most efficient allocation of VoD requests by estimating expected server load and expected user waiting time. In order to evaluate our algorithm, we conduct a simulation of an IPTV network and verify the effectiveness of our system by comparing it with two baselines (Least Load and Nearest methods). As experimental results, the proposed system performs significantly better than the baselines. Consequently, the system can manage limited network resources efficiently and enhance QoE.
