Embodiment Construction

[0025] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiment of the application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the application. Obviously, the described embodiment is only It is a part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0026] For the realization of the current service board, aiming at the target number of network ports and the speed of the network port, the required Field Programmable Gate Array (Field Programmable Gate Array, FPGA) chip is welded on the service board at one time. Once the board is produced, its size and the chips soldered on it have been determined, and it is di...

Abstract

The embodiment of the present application discloses a network tester, which includes a chassis structure, a power supply module, a system main control module, a clock module, a system backplane and a service board. The power supply module, system main control module, clock module, system backplane and service boards are fixed in the chassis structure. The power supply module, the system main control module, and the clock module are connected to the first plane of the system backplane, and the service boards are connected to the second plane of the system backplane. Among them, the service board includes a CPU module and an FPGA module. The CPU module establishes communication with the FPGA module. An FPGA module includes an FPGA device and a network port driven by the FPGA device. The CPU module and the FPGA module are detachable. Since the CPU module and the FPGA module are independent modules, and the FPGA module is divided into FPGA devices as the granularity, the upgrade or downgrade operation can be simplified, the cost can be reduced, and the changing needs of customers can be flexibly met.

Description

technical field [0001] The present application relates to the technical field of network testing, in particular to a network tester. Background technique [0002] A network tester is a commonly used instrument in network communication, which presents several Ethernet network ports to the user. Connect to the system under test through this network port. Through the configuration of the software interface, the user makes the network tester generate network traffic or initiate protocol interaction and send it to the system under test, and the response of the system under test is received and analyzed by the test instrument through the same network port or another network port, so as to realize test system. [0003] The service board is an important component of the network tester, and the test task is mainly realized through the service board. In the current network tester, different service boards need to be replaced to realize test functions with different port speeds and ...
