An Application of Artificial Immune Algorithm for Load Balancing in VOD Cluster

In view of the mechanism of artificial immune system has features of biomimetic adaptive, distributed, dynamic balance, and artificial immune system has the abilities of strong learning, memory, identification, extraction of the characteristics and so on, established an artificial immune algorithm for load balancing in VOD cluster. The testing results, compared with weighted round robin algorithm and weighted least connections algorithm, indicate that this algorithm reduces processor average time to complete the task, and increase the number of throughput and connectivity, and improve the handling capacity of the VOD server at no additional server or improving server configuration.
