%X A unified model for VoIP traverse of NAT and firewall was presented based on P2P networks.This model exploits the two-tied distributed P2P overlay network to develop an Optimal Path Establishment Algorithm(OPEA),through which the optimal solutions of NAT/FW traverse in varied scenarios are got.It is more effective and more robust compared to other solutions such STUN.Its feasibility and effectiveness in providing QoS were demonstrated through the implementation of a prototype with corresponding experiments on the campus network.
