Abstract: The present invention relates to a method based on the combination of UPnP and STUN for NAT traversal. 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.

Abstract translation: 本发明涉及一种基于UPnP和STUN组合的NAT穿越方法。 本发明的方法有效地利用了UPnP和STUN的优点。 特别地，当UpnP无法遍历NAT时，应用STUN第二次执行NAT穿越，从而有效提高成功遍历的效率。 对于对称NAT穿越，提供了基于NAT添加端口映射的端口添加样本估计方法，用于端口估计，以避免第三方代理造成的缺陷和投机方法的盲目性。 而且，P2P流媒体系统中的两个通信对等体都在NAT之后，提供具有足够带宽的普通外部对等体部分作为辅助中继对等体的方法，以释放中继服务器的压力 沟通的瓶颈被打破了。
