Embodiment
[0024] figure 1 As shown, a specific embodiment of the present invention is that a flow control transmission protocol message traverses the network address translation device, and the method is:
[0025] A, between the SCTP layer of the terminal using SCTP (Stream Control Transmission Protocol) and the Internet Protocol IP layer, add UDP (User Datagram Protocol) encapsulation / decapsulation layer;
[0026] B. The UDP encapsulation / decapsulation layer is at the terminal ( figure 1 The terminal that sends the SCTP message) encapsulates the message before sending the SCTP message, so that it has a UDP message header before sending it;
[0027] In this example, the UDP encapsulation / decapsulation layer encapsulates the message before the terminal sends the SCTP message: insert a standard UDP message header in front of the SCTP message header, and the destination port of the UDP message header The domain and local port domains are filled with the corresponding port information ext...
