• Abstract:

  The current conventional spectrum allocation method for single-path service optical networks mainly realizes spectrum allocation by centralized processing of instantaneous global channel state information, which is superior to the lack of effective processing of time-frequency fragments, resulting in poor allocation results. In this regard, a spectrum-aware spectrum allocation method for single-path service optical networks is proposed. Firstly, the analysis of time-frequency fragmentation probability is realized by comparing the duration of the connection request with the remaining duration of the allocated service on the selected link. And the dynamic spectrum allocation problem is solved by constructing a cooperative differential game model, and finally the spectrum allocation process is designed by combining the univariate marginal distribution algorithm. In the experiment, the proposed method is verified for the allocation effect. Finally, the experimental comparison results can prove that when the proposed method is used for network spectrum allocation, the average service damage rate of the algorithm is lower, and it has a more ideal spectrum allocation effect.
