Performance Evaluation of Load Control Techniques in SIP Signaling Servers

This paper is aimed at studying and evaluating the performance of two algorithms suitable for load control enhancement in "session initiation protocol" servers. A shrewd management of SIP call-control messages is key for the performance of telecom infrastructures, since SIP is rapidly gaining momentum to be the #1 protocol for session signaling in next-generation multimedia converged networks. The work will show simulation results related to the performance of a virtual server belonging to a real server SIP farm under both homogeneous and non-homogeneous traffic scenarios.
