P2P SIP is proposed to leverage Peer-to-Peer computing to control multimedia sessions in a decentralized manner. The deployment and maintenance cost of P2PSIP is reduced compared to conventional SIP. In this paper, we propose a hierarchical P2PSIP system to address the connectivity and overhead problems which haven't been solved in the P2PSIP literature. The hierarchical P2PSIP system is implemented under Linux, which demonstrates the feasibility of the proposed scheme. Finally, exhaustive simulations are performed to evaluate the performance of various P2PSIP schemes. Results indicate that the hierarchical approach not only solves the connectivity problem caused by heterogeneous overlays, but also performs more efficiently than the flat scheme when the percentage of nodes in the upper level overlay is less than 10%.
