Evaluation and Simulation on the Performance of DHTs Required by P2PSIP
Both SIP and various peer-to-peer protocols have been widely deployed, there is little operational experience with SIP using overlay networks. Also, some researches have proposed to leverage peer-to-peer computing to control multimedia sessions in a decentralized manner (P2PSIP) . However, most proposals in research only focused on the design of P2PSIP protocols using one specific DHT overlay. They don’t take full account of the DHTs performance requirements for a P2PSIP system and the differences between various DHTs. In this paper we will list the key properties of the DHTs and give a performance evaluation and simulation of the representative DHTs that have been proposed to be used in P2PSIP by IETF.
