摘　　要：针对开放网格服务环境OGSA中光网络资源调度需求问题,使用WSRF规范将光网络资源封装成WebService资源,使其像其他的服务资源一样可以通过统一的接口来调用。提出了在网格机制下的光资源调度策略和算法,在GridSim的基础上对光网络资源建模并对该算法进行了仿真。仿真结果验证了该策略的有效性,表明该算法能够在全局视图下有效地调度和均衡地分配资源请求,明显地提高了资源利用率。This paper discusses the requirements of optical networks scheduling in open grid service architecture, and then proposes a way that encapsulates an optical network resource as a web service resource by WSRF. Furthermore, a scheduling strategy and algorithm is proposed. Based on the GridSim, the optical networks model was constructed and the simulation of this algorithm was made. Simulation results validate the effectiveness of the strategy, and shows that the algorithm has abilities of scheduling Lambdachannel requests efficiently and equilibrating both requests and resources allocation in global view, raising the utilization of optical network resources obviously.
