A method, device, test board and system for testing interface board flow

Abstract

The present invention provides a method, a device, a test board, and a system for testing traffic of an interface board. The method comprises: acquiring a first test data packet; encoding and performing mapping processing on the first test data packet, to obtain a processed first data packet; converting the first data packet to a first data packet that can be received by a to-be-tested interface board, and sending the first data packet to the to-be-tested interface board; acquiring a second data packet returned by the to-be-tested interface board; converting the second data packet to a second data packet that can be received by a packet receiving module; decoding and performing mapping processing on the second data packet, to obtain a processed second data packet; and determining, according to a result of matching between the processed second data packet and the first test data packet, whether the to-be-tested interface board is faulty. The method in the present invention can improve test efficiency.

Description

Technical field [0001] The invention relates to the field of high-end routers, in particular to a method, a device, a test board and a system for testing the flow of an interface board. Background technique [0002] In advanced routers, the interface board is mainly responsible for the physical layer and data link layer work such as identification and access of physical lines, encoding and decoding, and framing. The stability of data access and processing of the interface board plays an indispensable role in the normal operation of advanced routers. The existing interface board tooling test method generally adopts the method of docking with a commercial line card and using a tester to send the stream. [0003] Such as figure 1 As shown in the schematic diagram of using a tester for testing, the tested interface board is connected to the tester through an optical fiber, the light-emitting port of the tester is connected to the light-receiving port of the tested interface board, and...

AI Technical Summary

Problems solved by technology

If you need to test multiple interface boards or multiple ports, you need to manually switch the interface board and the tester, the test efficiency is low, the degree of automation is not high, and it is not suitable for mass production

In this test method, the interface board is plugged with a commercial line card, which is expensive, and at the same time, expensive test instruments are connected externally, and the test cost is relatively high.
