Abstract
The present disclosure relates to a method, a system and a computer readable storage medium for controlling protection switching on an optical network. The method for controlling protection switching on an optical network includes: determining a low-frequency signal for service protection, and modulating the low-frequency signal for service protection to a transmission channel of a service signal to be protected and transmitting the low-frequency signal; detecting the low-frequency signal over the transmission channel and acquiring transmission quality information of the low-frequency signal; and determining whether to perform protection switching according to the transmission quality information of the low-frequency signal.
Claims10
A method for controlling protection switching on an optical network, comprising:
- determining a low-frequency signal for service protection, and modulating the low-frequency signal for service protection to a transmission channel of a service signal to be protected;
- detecting the low-frequency signal at any position of the transmission channel after a position for modulating the low-frequency signal, and acquiring transmission quality information of the low-frequency signal;
- and
- determining whether to perform protection switching according to the transmission quality information of the low-frequency signal.
A method for controlling protection switching on an optical network, comprising:
- acquiring information of a low-frequency signal for service protection;
- detecting the low-frequency signal at any position of the transmission channel of the service signal after a position for modulating the low-frequency signal, and acquiring transmission quality information of the low-frequency signal;
- and
- determining whether to perform protection switching according to the transmission quality information of the low-frequency signal.
