Problems solved by technology

[0003] However, these external test methods have their own defects. The hardware cost of external instrument test tools is very high, and the entry cost is also high, and the real-time performance is poor.
Plug-in software can't realize remote testing, and it needs manual entry
Existing protocol layer test methods usually require hardware to support high-speed message insertion capabilities, for example: 10M / s, 100M / s, 1000M / s, 10000M / s can meet the performance test requirements, and many old devices do not support it. And new device support will also increase hardware costs

Abstract

The present invention relates to a method and device for testing link performance. The method for testing link performance comprises: links to be tested are selected; links to be tested are connected in an order that forms a closed test link path; test packets are inserted into the closed test link path; the maximum speed that the closed test link path uses to transmit the test packets is the throughput of the links to be tested. The method and device for testing link performance presented in embodiments of the present invention utilize a test closed link path formed using a packet distribution network or using the links within the device itself, and obtains the performance of the links to be tested according to inserted test packets, thereby achieving low-cost, real-time link performance testing with no need to rely on other external devices.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a link performance testing method and testing device. Background technique [0002] For packet packet forwarding networks or devices in communication systems, it is necessary to test the performance of these packet forwarding networks and devices. Existing testing methods use test tools outside of these packet forwarding networks and devices themselves , such as external instrument test tools, plug-in software, network equipment embedded IP / ETH and other protocol layer test methods (such as Y.1731 TEST performance test method). [0003] However, these external test methods have their own defects. The external instrument test tools have high hardware costs, high entry costs, and poor real-time performance. Plug-in software also cannot realize remote testing, and requires manual entry. Existing protocol layer test methods usually require hardware to support high-speed message ...
