基于辅助图模型的IP+Optical网络跨层统一资源分配算法研究

his paper introduces cross-layer unified resource scheduling for IP+Optical network. Firstly the cross-layer network auxiliary graph model is introduced, and then the unified cross-layer scheduling algorithm is designed based on this model. By dynamically adjusting the weights of edges on the graph model, this algorithm can reflect the preference of network resource selection. The flexibility of optimization strategies can ensure that the network resources can be fully and rationally utilized. Simulation results show that, compared to traditional layer-independent algorithm, the proposed routing algorithm proposed can reduce the request blocking probability significantly, and the IP-first strategy is better than the optical-first strategy.
