Problems solved by technology

In addition, the launch of a stable version often requires multiple version changes, and testers need to conduct a large number of tests repeatedly. The test workload is very heavy and the test cycle is very long.
This feature of SDH network protection determines that the network protection project is usually the test project with the longest test cycle in the development of SDH equipment products. The test efficiency of the network protection system directly determines the product development cycle.

Abstract

The auto-test method for protective system of OSDN comprises: setting optical path controller to access the management system into the network; connecting the console, management system and devices; configuring protective process and testing business, as well as the parameters of SDH tester; starting the console, loading testing case, sending testing command to let all of the management system, controller and power controller execute command; acquiring network state and business information by the management system and SDH tester to provide to the console for analysis and process; finally, outputting testing result.

Description

technical field [0001] The invention relates to a test method for the optical synchronous digital transmission hierarchy (SDH) network protection system. Background technique [0002] The optical synchronous digital transmission system (SDH) network has a very complete network self-healing protection function. According to different protection working principles, ring network protection usually includes subnet connection protection (SNCP), two-fiber bidirectional multiplex section sharing protection, four-fiber Two-way multiplex section sharing protection, as well as protection methods such as wrong connection blocking, transoceanic switching; link protection usually includes multiplex section link 1+1 protection, multiplex section link 1:N protection, for link protection , It also includes one-way / two-way, return / non-return and other protection methods. For different SDH networks, it also includes dual-node network interconnection protection (DNI). The ITU-T G.841 and G.8...
