Adaptor-Based Design and Implementation of Peer-to-Peer SIP
SIP (session initial protocol) is a signaling protocol widely used in IP-based multimedia communication. Recently, P2PSIP reduces the deployment and maintenance cost, as well as improves the robustness and scalability of SIP-based system. SIP, P2PSIP network will coexist in the forthcoming future. This paper focuses on the P2PSIPand its relationship with SIP. We design and implement a P2PSIP adaptor, which allows traditional SIP UAs to access to P2PSIP network. This allows P2PSIP to reuse the work in traditional SIP and makes transition from SIP to P2PSIP seamlessly. The P2PSIP adaptor can also be utilized for P2PSIP interworking by two existing interworking approaches.
