摘　　要：在多粒度光网络中引入了一种资源预置策略,通过预置多粒度光网络中不同粒度的带宽资源,可以增加光网络的直达路由,优化选路和转接的性能,重建网络的拓扑结构.仿真结果表明,采用资源预置策略可以显著地降低控制平面的连接建立时间.To meet the requirements of multi-granularity optical networks for capability of switching at different granularities, a resource pre-configuration strategy is introduced into multi-granularity optical networks. By pre-configuring the resource of multi-granularity optical networks, the topology can be recon- structed with the number of direct routes increasing. The performance of routing and forwarding can be optimized. Numerical simulations show the connection establishing time of control plane could be significantly reduced by using resource pre-configuration strategy.
