Embodiment Construction

[0022] FIG. 1 is a structural diagram of the overall composition of the testing system provided by the present invention. As shown in the figure, the entire test system includes a test server S and test terminals A-F. Wherein, there may be multiple test terminals, and is not limited to the number shown in the figure. Test terminals A-F are deployed at key locations in the network, such as nodes close to each gateway in the LAN.

[0023] Referring to FIG. 2 , it is a functional block diagram of a partial composition structure of the system composition structure in FIG. 1 . As shown in the figure, a server test unit is deployed on the test server, and a terminal test unit is deployed on the test terminal. In a preferred embodiment of the present invention, both the server testing unit and the terminal testing unit are software. Moreover, the terminal test unit software on each test terminal can be distributed and installed through the test server, so the cost is very low.

Abstract

A method for carrying out on-line test on quality of digital network includes sending test UDP message to any set of test terminal used as master test terminal by test server, generating simulation flow rate to finalize test items and to obtain test result message with another set of test terminal used as subtest terminal by master test terminal, transmitting test result message to test server and sending configuration message to master test terminal by test server, repeating above said process till all nodes existed with test terminal are tested and generating test statistic report by test server.

Description

technical field [0001] The invention relates to the field of IP network communication, in particular to a method and device for online testing of the quality of a data network. Background technique [0002] Network managers need to frequently test and evaluate the network they build, analyze and solve network faults, optimize the network, evaluate the network carrying capacity and integrate network traffic, so that the network can run in an optimal state as much as possible. Therefore, network managers need some tools to obtain key performance indicators such as network end-to-end connectivity, throughput, packet loss rate, and congestion location, so as to provide important basis for analyzing network faults, overcoming network bottlenecks, and optimizing network traffic. [0003] In the prior art, the above-mentioned performance indicators are obtained mainly in the following way: deploying multiple test instruments in the network, and monitoring by remotely controlling tr...
