摘要: The proliferation of web services; and users appeal for high scalability, availability reliability servers to provide rapid response throughput the Clients’ requests occurring at anytime. Distributed Web Servers (DWSs) an effective solution improving quality services. This paper addresses un-regulated jobs/tasks migration among servers. Considering distributed services with several running, a lot bandwidth is wasted due unnecessary job migration. Having considered optimization, it important develop policy that will address consumption while loads/tasks are being transferred goal this work regulate movement minimize consumption. From literatures, little or no attention was given problem, making difficult implement some these policies/schemes in scarce environment. Our “Cooperative Adaptive Symmetrical Initiated Dynamic/Diffusion (CASID)” developed using Java Development Environment (JADE) middle ware service oriented environment which agent-based. software used simulate events (jobs distribution) on With transfer allowed when all busy, any over loaded server process jobs internally completion. We achieved by having two different agents; static cognitive agents dynamic agents. results were compared existing schemes. CASID outperforms PLB scheme terms time system throughput.
