支持多通道传输的光子网格资源并行调度策略

为满足分布式业务对资源使用灵活性和网络高带宽性的要求，实现高性能光网络，对光子网格体系结构进行了研究，并提出支持多通道传输的光子网格资源并行调度策略. 利用可分负载均衡策略分割数据或执行大文件分片，结合多波长并行预留机制，在应用驱动下按需分配光路资源. 构建光子网格实验平台，以电力分布式潮流数据传输应用为例验证所提策略的有效性. 实验结果表明，在应用驱动下并行调度策略能提供灵活的光网络资源分配，有效提高分布式业务的传输性能及光网络资源利用效率.

Resource Coordinated Scheduling Strategy Supporting Multi-Channel Transmission in Optical Grid

Network resource coordinated scheduling strategy supporting multichannel transmission is presented to implement highperformance optical network with high bandwidth and flexibility for distributed services under the researching of optical grid architecture. The divisible load theory is introduced into the strategy to divide data or bigbulk file. The parallel multiple wavelength reservation is combined with the applicationdriven mode. An optical grid testbed is designed to verify the feasibility of the coordinated scheduling strategy. The performance of multichannel transmission is analyzed through an example of the distributed computing about electric power flow. Experiment shows that the strategy can provide flexible resource allocation with optimizing the transmitting performance of distributed service and using efficiency of optical network resource. 
