A Novel Approach for Load Balancer in SIP Clusters

The paper describes a novel algorithms for a load balancer, distribute the work to the group of SIP server. The number of load balancing algorithms for distributing Session Initiation Protocol (SIP) request to a cluster of SIP servers. This algorithm also supports the following three techniques such as Call Join Shortest Queue, Transaction Join Shortest Queue and Transaction Least Work Left. It is combine knowledge of the SIP, recognizing variability in call length, dynamic estimates of back-end server load for different SIP transactions. In this paper depending on the configuration improves both throughput and response time. The protocol is extensible that means developers can easily write custom applications for SIP to accommodate video, VOIP, instant messaging and other emerging communications media features. We put forward in depth analysis of occupancy to show how our algorithms significantly reduce response time.
