Abstract
Although P2P-based VoIP systems are gaining attraction in recent years, supporting traditional telephony related use cases on them require various kinds of communication services. In this paper, we first exploit the system architecture design for P2P-based communication services by introducing the concept of social network. We also present an architecture design of P2Pphones, and test the effectiveness of this architecture by setting up a real world P2PSIP phone. Then, network topology is analyzed to study how P2Pphone can be related to social networks, and how social functionalities can benefit P2P-based VoIP systems. Examples of using social-based Gossip protocol for P2PSIP application are given in the later part.
