Network damage instrument and using method thereof

Abstract

The invention provides a network damage instrument and a using method thereof. The network damage instrument comprises a switching device and a controller; the controller is used for supplying power to the switching device in a power-on state; the switching device is used for establishing signal connection with the controller when the controller supplies power, and transmitting first network flowto the controller through the signal connection when receiving the first network flow from external network supply equipment; when the controller stops supplying power, the signal connection with thecontroller is disconnected, and when the first network flow from the network supply equipment is received, the first network flow is transmitted to external network equipment; and the controller is also used for generating a second network flow signal according to the first network flow signal and a preset network damage instruction when receiving the first network flow from the switching device,and transmitting the second network flow signal to the network equipment through the switching device. According to the scheme, the problem that the network equipment is disconnected when the networkdamage instrument is powered off can be solved.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a network damage meter and a method for using the network damage meter. Background technique [0002] With the development of Internet technology, more and more applications and network devices need to rely on the network to work. However, any long-distance network will have complex network damage conditions such as limited bandwidth, delay, packet loss, jitter, out-of-order packets, repeated packets, competitive traffic, congestion, and bit errors. In other words, it may reduce the performance of the application, and even cause the network application to be paralyzed. [0003] In order to analyze and test the above-mentioned network damage and test the final use effect of the network application in the real network, at this stage, for the above-mentioned network damage, the network damage tester is mainly used for fault injection. [0004] The network damage meter needs t...

AI Technical Summary

Problems solved by technology

[0004] The network damage meter needs to be powered on when it is working, but in practical applications, if the network damage meter is powered off, it will be paralyzed, which will make it impossible for the network damage meter to transmit the network traffic received from the network supply device to the network device , resulting in disconnection of network equipment
