| Summary: | Session Initiation Protocol (SIP) is a signaling protocol emerged with an aim to enhance the IP network capabilities in
terms of complex service provision. SIP server scalability with load balancing has a greater concern due to the dramatic
increase in SIP service demand. Load balancing of session method (request/response) and security measures optimizes
the SIP server to regulate of network traffic in Voice over Internet Protocol (VoIP). Establishing a honeywall prior to the
load balancer significantly reduces SIP traffic and drops inbound malicious load. In this paper, we propose Active Least
Call in SIP Server (ALC_Server) algorithm fulfills objectives like congestion avoidance, improved response times,
throughput, resource utilization, reducing server faults, scalability and protection of SIP call from DoS attacks. From the
test bed, the proposed two-tier architecture demonstrates that the ALC_Server method dynamically controls the overload
and provides robust security, uniform load distribution for SIP servers. |
