Problems solved by technology

[0004] Due to the high price of these test instruments, and the testing often requires multiple instruments to be used together, and there are few opportunities to use them, the cost of Internet testing is extremely expensive.
In practice, often because of the high cost of testing, a small number of sampling tests are used, or the network performance is not tested at all, which leads to the decline of Internet quality

Embodiment

[0119] This embodiment provides the path capacity test situation of a path composed of multiple routers by using the method of the present invention and the corresponding system. The path is based on multiple 155Mb / s ATM links and ATM switches.

[0120] The source point of the test is located at one end of the path in the computer room, which is located in a certain network center computer room in Beijing; the target point is the other end of the path, which is located in a certain computer room in Lanzhou. One main control system and two traffic generators are placed at the test source point, and one response system is placed at the test target point. The IP address of the main control system is IP s , the IP address of the responding system is IP d , the IP address of the traffic generator is IP s1 , IP s2 .

[0121] Configure the measurement parameters through the main control system. Select test index I, the tested path capacity value is 155Mb / s, the IP address of th...

Abstract

The test method includes: determining test source point and target point, setting host control system and flow rate generators connected each other and with tested path via LAN exchange inside the identical LAN in the source point; setting responding system in the target point; for the host control system configure test parameters and calculate automatically the number of required flow rate generators and the additional flow size and test flow size of each flow rate generator; for the host control system to handshake the flow rate generators and the responding system, for the responding system to return calculation result to the host control system and record after the host control system informs the responding system to finish test. The system of the present invention includes a host control system, a responding system and several flow rate generators.

Description

technical field [0001] The invention relates to a test method and system for Internet performance, in particular to a test method and system for Internet path capacity. Background technique [0002] In network engineering, an important step after the installation of the Internet is to test the performance of the network, and it is also necessary to measure its performance in the daily operation of the Internet, and even Internet users will pay great attention to the quality of the network. An important end-to-end performance parameter of the Internet is path capacity, and its packet loss rate characteristics need to be tested under rated traffic. For this reason, the Internet test equipment should produce accurate large-flow test data packets, and can test the relevant parameters of the network under this condition [1]. [0003] Existing Internet test instruments are mainly composed of special hardware and software entities, which have the characteristics of high measuremen...
