Stun protocol package needs to return to stun protocol package to it to the client of ICE server.Thus, ICE server sends data
Before, it can judge whether to be sent with UDT protocol package accordingly: if so, carrying out the conversion of stun protocol package to UDT protocol package；
If it is not, then stun protocol package is directly transmitted.The transmission of UDT protocol package uses UDT agreement, and the transmission of stun protocol package uses
Udp protocol.
In fact it is preferred to ground, the present invention provides following manner for the data transmit-receive of ICE server, wherein each ICE
Client (new edition) correspond to a specified UDT agent unit and communicate one of stun server of connection it is specified
The port stun.Specifically, receive the data that client sends over when ICE server, and when being judged as UDT protocol package, meeting
A UDT agent unit is generated for the client, and specifies a port stun of stun server for the UDT agent unit
Connection is communicated, the stun protocol package after conversion is sent to stun server.In the complete client of stun server process
After the data at end, stun protocol package is generated, and stun protocol package is returned into the port stun that transmission data come.Pass through institute
It states the specified port stun and is sent to the specified UDT agent unit for communicating connection, the UDT agreement after converting
Packet returns to the ICE client (new edition).And each ICE client (old edition) correspond to one of stun server it is specified
The port stun.
Correspondingly with the above method, ICE serving system architecture of the invention is as shown in Figure 1.
