Analysis of Delays in a Peer-to-Peer Session Initiation Protocol Overlay Network
Jouni Mäenpää, Gonzalo Camarillo · 2010
Peer-to-peer session initiation protocol (P2PSIP) is a new decentralized person-to-person communication system that is currently being standardized in the Internet Engineering Task Force (IETF). P2PSIP uses the session initiation protocol (SIP) to enable real-time communication in a peer-to-peer environment. The underlying lookup mechanism is implemented using a distributed hash table (DHT). In this paper, we study delays associated with joining, leaving, and initiating calls in a P2PSIP system through experiments in PlanetLab. We also compare the performance of P2PSIP and traditional client-server SIP.
