光子网格中支持并行传输的多用户按需光路共享机制研究

On-demand multi-user lightpath sharing through parallel transmission in optical grid networks

提出了一种面向光子网格网络的共享光路供给机制,使得多个网格作业可以根据其动态需求,在执行时间内共享同一条端到端的光路。通过网格作业的有效汇聚,光路上的网格业务速率可以最大限度地接近链路所支持的最大速率。实验表明,相比于传统使用专有光路的光子网格网络,该机制在保证服务质量的基础上可明显提高网络资源利用效率。

A lightpath sharing provision method for optical grid networks was proposed. It enables multi grid jobs employ one lightpath simultaneously according to their dynamic requests in their execution time. By aggregating multi grid jobs effectively, data transfer rate of gird applications on the lightpath could approach the maximum bandwidths supported by the lightpath. Experimental results show that, compared to conventional dedicated lightpath based optical grid networks, the proposed scheme could improve network resource utilization remarkably while the QoS of grid application is guaranteed.
