How to use the network damage tester and the network damage tester

Abstract

The present invention provides a network damage tester and a method for using the network damage tester, comprising: a switch device and a controller; the controller is used to supply power to the switch device when it is in a power-on state; the switch device is used to communicate with the controller when the power is supplied The controller establishes a signal connection, and when receiving the first network flow from the external network supply equipment, transmits the first network flow to the controller through the signal connection; when the controller stops power supply, disconnects the connection with the controller Signal connection, and when receiving the first network traffic from the network supply equipment, transmit the first network traffic to the external network equipment; the controller is also used to receive the first network traffic from the switching device, Generate the second network traffic signal according to the first network traffic signal and the preset network damage instruction, and transmit the second network traffic signal to the network equipment through the switching device. This solution can solve the problem of disconnection of the network device when the network damage meter is powered off.

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
