Assembling Algorithm of Optical Burst Switching Network under Multiple Performances Restriction

在综合分析光突发交换网络中组装算法对控制平面处理时延、数据平面资源利用效率和数据平面突发丢失率等多种性能指标的影响的基础上,提出了一种能够同时满足多种网络性能指标约束的边缘节点动态组装算法。该算法根据全网目标性能指标的约束,动态调整组装输出的突发长度和突发时间门限,从而实现同时满足全网链路资源利用率和控制平面突发丢失概率的双重性能约束。

The paper proposed an assembling algorithm for edge node of the optical burst switching networks.The algorithm can satisfy multiple network performances at the same time.The foundation of the algorithm is based on the analysis of the impaction of assembling algorithm on control plane＇s end to end delay,resource utilization of data plane and the drop ratio of the burst.The algorithm can adjust the time threshold and the queue length threshold according to the network performances＇ restriction,and satisfies the desired performance of resource utilization and burst drop ratio at the same time.
