A survey on peer-to-peer SIP based communication systems

Published version of an article from the journal: Peer-to-Peer Networking and Applications. The original publication is available at Spingerlink. http://dx.doi.org/10.1007/s12083-009-0064-4Recently, both academia and industry have initiated research projects directed on integration of P2PSIP paradigm into communication systems. In this paradigm, P2P network stores most of the network information on each participating peer without help of the central servers. The concept of self-configuration, self-establishment greatly improves the robustness of the network system compared with the traditional Client/Server based systems. In this paper, we survey P2PSIP solutions proposed recently both in the academic and industrial research. We consider technical issues that include Chord overlay topology, P2PSIP session initiation (including enrollment and bootstrap, NAT traversal, message routing, P2PSIP interworking, P2PSIP Client, etc), and security issues. Our survey is based on recent research publications. © 2010 Springer Science + Business Media, LLC
