(The methods and means of network testing vary with the purposes of testing. There are two typical network equipment testing methods: the first is to put the equipment in a simulated network environment and test the product by analyzing its behavior in the network; The second method is to use special network test equipment to test products, such as special performance analysis instruments smartbits2000, ixia1600, etc. There are also special tools for the wiring test, physical connectivity test and fault monitoring of the network system. These tools are some low-level network testing and maintenance tools, such as fluke's network stethoscope, network all-in-one, enterprise network tester, etc. Network cable tester, token ring network tester, Ethernet tester and optical cable tester are common test tools used in the implementation, deployment, operation and maintenance phase of the network system. Generally, there are special testing tools to support the conformance testing of network protocols. For example, there are special testers for the implementation of ISDN, ATM, ADSL, frame relay, etc. There are also some network performance testing tools at a higher level than the protocol analyzer. From the perspective of the application layer, some benchmark traffic is used to analyze the performance of the network system. The representative software is chariot software of ganymedesoftware.)
