Embodiment Construction

[0031] see figure 1 As shown, the delay calibration device provided by the present invention is connected to the network performance tester and the console respectively when performing the delay calibration operation. The network performance tester sends the Ethernet data frames for testing (including but not limited to Ethernet II, IEEE802.3 format data frames) from one port to the delay calibration device, and the delay calibration device receives the test Ethernet data frames The data frame is sent back to the network performance tester through another port after delay processing. Then compare the time delay added by the time delay calibration device with the time delay measured by the network performance tester. The value obtained by the network performance tester is calibrated by using the value of the delay calibration device. The console is realized by PC. The console is respectively connected with the network performance tester and the delay calibration device, and ...

Abstract

The invention discloses a time delay calibration device for network performance testing instruments and also discloses a method for time delay parameter calibration by the time delay calibration device. The time delay calibration device comprises a serial interface, a control unit, a time delay control unit, a memory and an Ethernet interface circuit; wherein, the time delay control unit is connected with the control unit, the memory and the Ethernet interface circuit respectively, and the control unit is connected with the serial interface which is used for connecting a console. The Ethernet interface circuit is used for connecting the network performance testing instruments. The time delay calibration device controls the corresponding memory by FPGA to realize the addition of the time delay, and the accuracy of the time delay addition has no relation with the line rate. Meanwhile, the accuracy of the time delay addition is high, which can meet the time delay parameter measurement and calibration requirement of the most accurate network performance testing instruments at present.
