Method and system for testing consistency of WAN (Wide Area Network) interface protocols

The invention discloses a method and system for testing consistency of WAN interface protocols, relating to the technical field of data communication. The method comprises that a PC set forms an auxiliary test device 2 and an auxiliary test device 3 via virtualization; a preset tunnel is established between the auxiliary test device 2 and an auxiliary test device 1, and the preset tunnel is used for realizing transparent message transmission between the auxiliary test device 3 and tested equipment; the auxiliary test device 3 transmits a to-be-tested interface protocol to the tested equipment via the preset tunnel; and the corresponding tested equipment generates response information according to the to-be-tested interface protocol, and transmits the response information to the auxiliary test device 3 via the preset tunnel. The method and system is mainly applied to the process of interface protocol; and can simplify the test process and substantially reduce the test cost in the process of testing the compatibility of the WAN interface protocols in network communication; and the method and system are mainly applied to the interface protocol testing process.
