Abstract
The present invention provides a method and system of OSNR-sensing spectrum allocation with optical channel performance guarantee. The method includes constructing an OSNR evaluation model; acquiring the shortest path between a source node and a destination node; acquiring a plurality of modulation formats and corresponding thresholds, sorting the plurality of modulation formats in descending order, and acquiring a list of the sorted modulation formats; calculating the bandwidth required by the lightpath service based on the bandwidth demand and FEC overhead by using the modulation format with the highest spectrum efficiency; substituting the bandwidth required by the lightpath service into the OSNR evaluation model and obtaining the number of FS actually required by the service; and allocating the spectrum resource required by the current service to the shortest path by using a first-fit algorithm and obtaining the center frequency of the current service on the lightpath.
