P2P streaming media application must realize NAT traversal.The UPUN algorithm is recommended in this paper to in-crease the success rate of NAT traversal,which is the combination of UPnP and STUN.This paper also presents the algorithm of Port-Adding Sample Estimation(PASE) and Peer Auxiliary-Relay(PAR) to improve traditional methods used in symmetric NAT traversal and the situations which both side peers are behind NATs.Experiments show that the algorithms achieve good performance.
