Implementation of Load Balancing Using SIP?

The concept of server clusters for efficient and faster working has been extensively implemented through the use of Session Initiation Protocol (SIP). The load balancing for these clusters have been a major challenge in the better implementation of such systems. The requests that are received in a single session are sent to same load balancer to be serviced by same server. This paper implements and evaluates the load balancing on the server clusters. SIP Transaction occurs between a client and a server and comprises all messages from the first request sent from the client to the server up to a final response sent from the server to the client. The performance of the algorithm is measured through the attributes like response time taken to service the request and memory utilized for the execution of the algorithm. The proposed system is expected to significantly reduce response time which will be confirmed through the inputs and the recorded output. We have used the concept of threads which are treated as the load to the load balancer and use the load balancing algorithm for providing significantly better response time by distributing requests across the cluster.
