Problems solved by technology

However, since this test method needs to connect each branch interface of the device under test 101 to the data tester 102, the test is complicated and expensive, and because it is manually operated by the data tester to send a package for testing, it takes a lot of time, thus affect overall productivity

Embodiment Construction

[0082] An OTN service testing method, terminal and system provided by the present invention will be described in more detail below with reference to the accompanying drawings and embodiments.

[0083] An embodiment of the present invention provides an OTN service test method, which is applied to a test architecture composed of a test terminal, a first device under test, M second devices under test, a data tester, and an OTN network; wherein, The first device under test, each second device under test and the data tester are all connected to the test terminal; the first device under test and the second device under test are respectively set on both sides of the OTN network to exchange OTN services through the OTN network ; The data tester is connected with M second devices under test. Among them, this method is executed by the test terminal, such as figure 2 As shown, the method at least includes the following steps 210 to 230 .

[0084] Step 210, select an untested service t...

Abstract

The embodiment of the invention discloses an OTN (Optical Transport Network) service test method, terminal and system. According to the scheme, for a selected target service type which is not tested, corresponding links are connected in series to form a self-annular two-way test channel. A data tester, a first tested device and a second tested device are smartly controlled to carry out transmission test of the service stream of the target service type on the two-way test channel in currently traversed ODU (Optical channel Data Unit) time slot mapping and multiplexing modes. In this way, synchronous coverage tests of the service transmission carried out by various links under different service types and different ODU time slot mapping and multiplexing situations can be realized, the stable and delay situations of an OTN system are determined, and the test efficiency and the test effect are improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an optical transport network (Optical Transport Network, OTN) service testing method, terminal and system. Background technique [0002] The OTN system involves a variety of business types, including Synchronous Digital Hierarchy (SDH), such as Synchronous Transfer Module (Synchronous Transfer Module) 1, STM4, STM16 and other granularities, and General Electric (General Electric, GE) etc. business type. [0003] During the OTN service access test, the bit error performance verification of one of the SDH or GE services is generally performed, and different service types will be multiplexed into different Optical Channel Data Units (Optical Channel Data Unit, ODU), involving For different cross-connect combinations, only testing one or a few channels does not mean that the bit error performance of all channels is normal. Therefore, under strict test requirements, al...
