Embodiment Construction

[0031] The invention provides a protocol testing device and a testing method. During testing, the protocol testing device of the present invention is placed in a network line, receives a message sent to the testing device by a device on one side of the network, and the testing device modifies the message report according to the test requirements. text, and then send it to the device on the other side; after the message returned by the device on the other side is sent to the test device, the test device analyzes the message according to the aforementioned test requirements, and then modifies the message and forwards it to the device on the original side , so as to achieve the purpose of testing the protocol between the two devices. In general, the present invention can quickly test whether the protocol transmission is normal by capturing, distinguishing, modifying, and modifying the protocol flow and protocol fields by sending messages.

[0032] The present invention will be de...

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...
