Abstract

SIP becomes one most poplar protocol in real-time multimedia services, but the central server becomes the single point of failure, While P2P becomes "killing level application" in Internet because of its robust and low cost. Combing P2P and SIP, we propose hybrid P2P SIP framework in the paper, and describe several important procedures, such as node registration, user registration and call procedure. But current P2P searching and routing arithmetic does not meet the requirement for low time delay in real-time multimedia applications. Then, we present a novel SOMCO arithmetic, which decreases the call delay and media forwarding delay to some extend. Simulation verifies that SOMCO is practical to support real-time multimedia services
