METHOD FOR CALCULATING OPTICAL CHANNEL OSNR IN REAL TIME BASED ON WSON NETWORK CONTROL PLANE

WIPO Patent Application WO/2018/227983

A1

Disclosed is a method for calculating an optical channel OSNR in real time based on a WSON network control plane, relating to the field of optical channel designs. The method comprises the following steps: S1. calculating an OSNR of an optical multiplexing section according to control planes at two ends of the optical multiplexing section and each station OSC disk of the optical multiplexing section; S2. taking the OSNR of the optical multiplexing section as the OSNR of a TE link corresponding to the optical multiplexing section, and recording same in a TE link attribute; S3. flooding information about the TE link attribute to a TE link database of each control node in real time; S4. repeating steps S1 to S3, so as to obtain the OSNRs of the remaining TE links in a WSON network, and flooding information about the remaining TE link attributes to the TE link database of each control node in real time; S5. calculating a channel route, so as to obtain a TE link set corresponding to the channel route; and S6. according to the obtained TE link set, finding the OSNRs of the corresponding TE links from step S4, and calculating an optical channel OSNR. In the present invention, an optical channel OSNR can be calculated in real time.
