“…The growing utilization of IP routed multimedia communications challenges for exceptional levels of reliability from signaling protocol like SIP. Reliability of SIP system includes signaling reliability [1], server reliability [19][20] [21] and reliability during mobility [22]. In this research work, we proposed a technique for improving the SIP system reliability, by improving the signaling reliability through SRSIP signaling and server reliability through ASP Queuing Strategy.…”

Session Initiation Protocol is an IP based application level signaling protocol. SIP employs request retransmission for enabling reliability over UDP transport. This research work proposes a Hybrid SIP System that integrates the congestion control techniques from the proposed Smart Reliable SIP and Overload control using Advanced Smart Priority (ASP) Queuing Strategy. The proposed system reduces retransmissions and queuing delays in SIP servers. Smart Reliable SIP (SRSIP) implements the modified Selective Repeat ARQ protocol for enabling reliability of SIP requests without violating the SIP core functionality. SRSIP reduces the number of retransmissions. ASP Queuing Strategy prioritizes the SIP requests based on the retransmissions. The proposed system reduces the queuing delays for request processing at the downstream server and the retransmissions over the network. The Hybrid models integrates the features of both Smart Reliable SIP and ASP queuing strategy resulting in a system with almost zero retransmissions and reduced queuing delay for request processing.

“…But these retransmissions results in backward compatibility issues. H. Zheng and S. Wang studied the inconsistency in SIP signaling due to mobility and proposed a Chain-Based SIP signaling [22]. Hop by hop reliability for UDP signaling was proposed by Reliable UDP (RUDP) [33].…”
