Embodiment Construction

[0018] Basic structure of the test framework of the present invention

[0019] Referring to FIG. 1 , this is the basic structure of a typical test architecture for testing SIP entities. The basic structure includes SUT 10 (system under test), two negotiators 11 and 12 (running on different computers respectively). The SUT 10 and the Negotiators 11, 12 are connected to the same network 30 using a connection method 20 which is based on TCP or UDP. Furthermore, the negotiators 11 , 12 are connected to the TestDirector 13 through any predetermined control protocol, which can be easily designed and implemented by a person skilled in the art, thereby receiving commands from the TestDirector 13 . Both the negotiator and the test guide are realized by software, and can be written by computer programmers using a suitable computer programming language, such as basic, pascal / delphi, c / c++, java, c#, etc. (only a few are cited here). Although the Negotiator and TestDirector are shown ...

Abstract

Architecture or system for testing the compatibility or robustness of communication signaling protocols used by entities connected to an IP-based network, in particular for testing SIP enabled entities or devices. Within this architecture, multiple test clients are coordinated by a centralized test controller, so that test progress and results can be controlled and monitored in a centralized manner. The architecture uses simple template-based test script commands that are easy to write and do not involve complex programming structures.

Description

technical field [0001] The present invention relates to a method and system for testing communication protocols used in networks such as the Internet. More specifically, the present invention relates to a testing method and system for testing the compatibility and robustness of a device using a specific signaling protocol to communicate with other devices using the same signaling protocol, in particular, For example Session Initiation Protocol (SIP). Background technique [0002] For example, network communications running over the Internet require a signaling protocol to establish presence, find users, and initiate, modify, or terminate sessions. One signaling protocol that is currently popular is the Session Initiation Protocol (SIP). This is the protocol used for web conferencing, telephony, presence notifications, event notifications, and instant messaging. SIP was developed within the IETF MMUSIC (Multiparty Multimedia Session Control) working group and has since rap...
