Protocol testing apparatus and method thereof

Abstract

The invention discloses protocol test equipment including first interface unit, second interface unit, protocol test unit, control unit and management unit. The invention also discloses a protocol test method. The protocol test equipment is connected between source device and destination device. The method includes following steps: (1) obtaining first message packet sent by source device; based on test rule, modifying content of the packet; sending the modified packet to destination device; (2) obtaining packet of response message to the modified packet from destination device; analyzing whether packet of response message is a packet accorded with stated test rules. The invention realizes categoricalness of test, and the test can simulate abnormal condition rapidly.

Description

technical field [0001] The invention relates to the technical field of testing, in particular to a protocol testing device and a testing method. Background technique [0002] Such as figure 1 An NGN network is shown, in which ABNF (ABNF is a grammatical format describing a communication protocol, see RFC 2234) grammatical description (for example, H.248 , MGCP or SIP, etc.) for communication, and the MG includes a trunk media gateway (TMG), an access media gateway (AMG), an integrated access device (IAD) and the like. With the gradual maturity of the NGN network, interoperability tests of equipment from different manufacturers are also gradually carried out. [0003] For NGN, the network contains different devices, and different protocols or signaling may be used between different devices. For example, in the process of calling the IAD on the PSTN side, the protocol for completing call message exchange includes narrowband SS7 (ISUP) protocol, broadband signaling M2UA (car...

Problems solved by technology

[0006] This test method requires a test device to simulate a device in the network to complete the test. It is difficult to comprehensively test the entire process, and it is even more difficult to test the completeness of the protocol in a real actual network.

This is because, for the test under this method, a complete process needs to be recorded on the test device to perform process-based information interaction with the device under test, and the process is usually flexible and complex, and the processes of different manufacturers may not be the same. same

Therefore, it is difficult for the simulation software to adapt to different manufacturers' equipment, and it is difficult to achieve the completeness of the test

On the other hand, since the stored process cannot be the various situations that can be encountered in the real world, it is impossible to simulate the real situation and deal with some special tests in the real situation

For example, when it is necessary to test the signaling between the softswitch and the PSTN network, but the signaling gateway (SG) is required, the signaling at this time will become complicated, and it is difficult to complete the test by the test device
