Problems solved by technology

[0005] At present, the test of OTN protection switching time is generally a manual test, and the judgment standard for whether the test is qualified is relatively fixed (different testers are divided into different judgment standards, and the judgment standard is generally 1 time point), not only the completion of the test The workload is large, human resources are consumed, and the test time is long, and the test efficiency is low

Embodiment Construction

[0044] see figure 1 As shown, the OTN protection switching automatic test system provided by the embodiment of the present invention includes a network management server software platform, a switch, a bit error analyzer, a fault detection device and at least one OTN device. The server software platform is respectively connected to the error code analyzer and the fault detection device through the switch; the code error analyzer, the fault detection device and at least one OTN device form a closed main line, and the code error analyzer and at least one OTN device form a A closed backup line.

[0045] The fault detection device in this embodiment is at least one of a controllable power supply, an optical switch, and a FTB500 fault error analyzer. There are three OTN devices: the first node OTN device, the relay point OTN device and the last node OTN device. The error code analyzer, the OTN equipment of the first node, the fault detection device, the OTN equipment of the relay ...

Description

technical field [0001] The invention relates to the field of OTN (Optical Transport Network, Optical Transport Network) protection, in particular to an OTN protection switching automatic test system, method and device. Background technique [0002] With the rapid development of optical communication technology, optical communication has developed from electrical layer network to optical layer network. OTN is a transport network based on WDM (Wavelength Division Multiplexing, wavelength division multiplexing) in the optical layer organization network; with the rapid growth of social information demand, OTN has become the main technical requirement of the next generation backbone transport network. [0003] Due to the high rate and large capacity of optical signals transmitted in OTN, the survivability of OTN (the ability to maintain acceptable service quality after various failures or even disasters, that is, the ability of the network to resist failure) is better than that o...
