摘要
传统OBS网络汇聚算法没有综合考虑边缘节点汇聚算法和核心节点的数据调度算法二者之间的相互联系,其通信性能受限。在分析OBS网络边缘节点汇聚算法对核心节点数据调度的影响后,提出了一种新的边缘节点汇聚算法——基于OBS网络的拥塞控制汇聚算法(CCAA)。该算法通过分析边缘节点汇聚参数对数据调度的影响,调整汇聚算法实现对核心节点调度成功率的影响,最终实现了提高核心节点数据调度的成功概率。
The communication performance of optical burst switching（OBS）networks is limited because the interaction between the assembly algorithm of edge nodes and the data scheduling algorithm of core nodes isn＇t considered in traditional OBS network assembly algorithm.After analyzing the influence of the assembly algorithm of edge nodes on the data scheduling of core nodes,we proposed a novel assembly algorithm of edge nodes,i.e.congestion- control-based assembly algorithm（CCAA）in OBS networks.The algorithm improves the success probability of core-node-data scheduling and enhances the performance of OBS networks by analyzing the influence of the assembling parameter of edge nodes on data scheduling and adjusting the assembling algorithm to affect the success rate of core node scheduling.
