Testing method for interchanger transmission signal performance and testing system

Abstract

The invention provides a testing method for interchanger transmission signal performance and a testing system, and belongs to the technical field of the interchanger test. The testing method comprises the steps: setting test duration, capture package file size, and network card corresponding relationship; configuring the IP address of network card 2 and a camera and a port 2 of the interchanger in the same network segment; configuring an in-direction flow mirror image of an interchanger port 3 to a port 1 connected with the network card 1; starting a timer, sending a command to the network card 1 and the network card 2, performing the continuous capture package by the network card 1 and the network card 2 and storing; and comparing the files one by one captured by the network card 1 and the network card 2 and recording the differences. The invention further provides the testing system for realizing the testing method. The configuration, capture package and comparison of the network cards and the interchanger are automatically completed, a tester only needs to construct the environment according to the network diagram, and open the device to test. The operation is simple, the judgment result is reliable, the test time can be freely set, and the test efficiency is improved.

Description

Technical field [0001] The invention relates to switch testing technology, in particular to a testing method and testing system for switch transmission signal performance. Background technique [0002] The scene of video surveillance is that a camera is arranged at the front end, and the camera compresses the collected image signal into a digital signal, and then transmits it to the server through the switch. Customers can watch or replay in real time on the server. [0003] Video surveillance requires clear and accurate without frame loss and error after passing through the transmission equipment. This is the most important performance requirement for the switch. How to test the performance of the switch efficiently and reliably is the key work of the switch manufacturer. [0004] The current test method is based on the camera-switch-server networking. The tester can visually observe whether there is a jam or missing images, and then compare the size of the source and destination ...

AI Technical Summary

Problems solved by technology

[0005] (1) The accuracy of manual viewing is not high, and it cannot be watched for a long time, so the test efficiency is low, and the test results are not reliable;

[0006] (2) The size of the two video files is the same, but there is no guarantee that there are no wrong frames.
