[0037] like figure 1 As shown, the ASON-based dynamic rerouting automated testing method in the first embodiment of the present invention includes steps:

[0038] S1. Deploy an optical switch between any two adjacent network elements in the network topology, configure a bit error analyzer for monitoring services in the network topology, set up a network manager for assigning IDs or circuit names to initial working routes, and set A control machine connected to the optical switch, error code analyzer and network management respectively, and realizes all configuration initialization.

[0039] Specifically, an optical switch has at least one channel, and at least one channel can be defined as a breakpoint bpi, where i is the sequence number of the breakpoint, and the initial setting of the breakpoint is a connected state (that is, the optical switch interface is set to on). When the breakpoint is disconnected, the optical switch corresponding to the breakpoint is set to the off ...

[0046] On the basis of the first embodiment of this embodiment, the premise of step S2 is: the control machine controls the network management to configure the initial working route, and the network management assigns an ID or circuit name to the initial working route, and returns the allocated ID or circuit name to the control machine store. Then the control machine controls the service configuration of the error code analyzer, and the configured service type is obtained from the self-defined information of the basic information. After the configuration of the bit error analyzer service is completed, monitor whether the bit error analyzer service is on or off. If the BER analyzer is abnormal, delete the configured route and end the test. Automated testing starts only when business is normal.

[0048] On the basis of the second embodiment, in this embodiment, as figure 2 As shown, step S2 specifically includes:

[0049] S201. The control machine reads the current route through the network management system, and the current route can be obtained through the ID or circuit name of the initial working route. Among them, the route read for the first time is the initial working route of the test.

[0050] S202. The control machine automatically generates a breakpoint of the next step in the test and an expected route set corresponding to the breakpoint according to the current route. Specifically, the control machine analyzes all possible breakpoints on the current route according to the current route, and then generates a certain breakpoint through a random algorithm. The generated breakpoint must be on the current route, and this breakpoint is used as the test control in the next step. the breakpoint. Then, according to all possible routes under the breakpoint, an ex...

Abstract

The invention provides a dynamic rerouting automatic test method and system based on an ASON (Automatically Switched Optical Network), and relates to the field of automatic test. The method comprisesthe following steps: step S1, deploying an optical switch between any two adjacent network elements in a network topology, setting a control machine to control the optical switch, and an error code analyzer of a web master and monitoring services, and initializing all configurations; step S2, automatically generating and testing a breakpoint in the next step and an expected route test corresponding to the breakpoint by the control machine through the current route read by the web master, and controlling the breakpoint to generate routing switching by the control machine through the optical switch; step S3, after each route switching is successful, selecting at least one optimal expected route in the expected route set by the control machine, and comparing with a route after switching; andstep S4, repeating steps S2 and S3 until the test is completed. According to the dynamic rerouting automatic test method based on the ASON provided by the invention, the test step is dynamically generated according to the current test condition, and the automatic test of the dynamic route is realized, thus various disadvantages caused by manual test are avoided, and the accuracy of a test result is improved.

Description

technical field [0001] The invention relates to the field of automatic testing, in particular to an ASON-based dynamic rerouting automatic testing method and system. Background technique [0002] The concept of ASON (Automatically Switched Optical Network) was proposed by the International Telecommunications Union in March 2000. The basic idea is to introduce a control plane into the optical transport network to realize the on-demand allocation of network resources and realize the intelligence of the optical network. To enable the future optical transport network to develop into a network that provides connections to any place and any user, and becomes a network composed of thousands of switching nodes and tens of millions of terminals, and is an intelligent fully automatic switching optical network. network. [0003] ASON is an automatic switching transport network based on SDH (Synchronous Digital Hierarchy) and (Optical Transport Network, Optical Transport Network). It u...
