Abstract:

Based on the immune stability maintenance mechanism, a load-balance and service-oriented architecture (SOA) model was proposed. First, the immune stability mechanism and the load balance of SOA Web service were analyzed, and an immune-based extended SOA framework was also proposed. Then, a dynamic load-balance model for Web service was further studied, and a two-phase load-balance optimization algorithm was developed. The capability of the load balance of this model working on a multi-agent simulation platform was also investigated. The experiments and analysis showed that the immune-based model could improve the performance of load balance for Web service and reduce the failure rate of requests.

Key words: Web service, immune stability maintenance, artificial immune system, load balance, service-oriented architecture, multi-Agent systems
