A Globally Overlaid Hierarchical P2P-SIP Architecture with Route Optimization
Huei-Wen Ferng, Iwan Christanto · IEEE Transactions on Parallel and Distributed Systems · 2011
In this paper, a three-level P2P-SIP architecture employing SIP servers is proposed for the overlay network. The proposed architecture achieves global overlay and has the capability of solving the triangular routing problem for the domain-based P2P-SIP architecture to reach route optimization. Demonstrated by our numerical results, the proposed architecture can exhibit its superiorities over the closest-related architectures in the literature in terms of message rate, latency, and physical hops count.
