The method of the present invention effectively takes the advantages of UPnP and STUN. In particularly, when UpnP fails to traverse NAT, STUN is applied to perform the NAT traversal for the second time, so that the efficiency of the successful traversal is effectively improved. For the symmetric NAT traversal, a Port-Adding Sample Estimation method based on NAT adding port mapping is provided for port estimation, to avoid the defects resulted from the third-party agent and the blindness of the speculation approach. And, where both of the communication peers in the P2P streaming media system are behind NAT, the method that the part of the ordinary outer peers with the sufficient bandwidth acts as the Auxiliary-Relay peers is provided to release the pressure of the relay server so that the bottle-neck of the communication is broken through. |
