Research on NAT Interconnection Based on UDP Switch Router
基于UDP交换路由的NAT互联技术研究

A new NAT Interconnection method based on UDP switch router has been presented.Firstly,the paper gives the message format using and protocol operation.Then,an example using SIP protocol has been discussed and analyzed in detail.The new method avoids the bottle-neck of TURN protocol on TURN server,and can improve the efficiency of communication between NATs.On the other hand,using of RID,SID and DID is the application of separating router identifier and session identifier,so our method can resolve the validi...
