Data communication equipment testing system and method of imitation multiuser, multi connection

Abstract

The system includes computers at client ends, computers at server ends, communication network built and network cards installed at client and server ends for communication connection. The method includes following steps: testing network initialization; using ARP request to parse MAC address of gateway device; bulding up TCP connection between client end and server end; sending TCP data message to server end; the server end answering back the said TCP data message to carry out testing data communication devices; finishing testing, based on TCP connection built, sanding message to serever end to disconnect TCP connection. In the invention, testing can be carried out fully when number of users and number of connections for a device to be tested are close to limit or exceed system limit. The invention possesses features of low testing cost, easy of implementation, and expansible quantity of device.

Description

technical field [0001] The invention relates to data communication equipment, in particular to a multi-user, multi-connection data communication equipment testing system and method for simulating a real data network communication environment in a laboratory. Background technique [0002] When testing data communication equipment, testers usually use the method of establishing a connection with one computer or several computers, performing data transmission and disconnection between computers, and repeating this cycle. Complete testing of data communication equipment. However, using this method, if you want to simulate a multi-user situation, you need multiple computers, and in the laboratory, due to the limitations of conditions, the users to be simulated by this conventional method are limited by hardware conditions, such as in Can the system work normally when the number of users exceeds 100? How does the system work when the number of users ...

Problems solved by technology

However, using this method, if you want to simulate a multi-user situation, you need multiple computers, and in the laboratory, due to the limitations of conditions, the users to be simulated by this conventional method are limited by hardware conditions, such as in Can the system work normally when the number of users exceeds 100? How does the system work when the number of users exceeds 1000? It is even more impossible to fully test whether it will crash when the number of users and connections exceed the system limit. What is the performance when there are multiple users? etc., because it is unrealistic to use 1000 or more computers to test in the laboratory at the same time, and the direct consequence of not doing limit testing is that when the equipment is close to the limit or exceeds the system limit, it is likely to cause the system to crash. The consequences and economic losses are self-evident;

[0003] On the other hand, some test instrument manufacturers also manufacture some special test instruments that can send specific messages, but the situation simulated by these instruments is different from the real network environment

When a real user works on the network, a group of different messages are organically combined through a specific sending and receiving sequence and the correct connection between messages to complete a task performed by a user, while existing test instruments only It can simulate a segment of the process, but cannot simulate the entire operation process performed by the user, so the test of the device under test is incomplete

Moreover, these special test instruments are expensive, usually in the range of one million to several million yuan.
