【摘要】：针对目前大规模软件定义数据中心网络流量路由机制中可扩展性低所带来的性能瓶颈问题,该文提出一种面向树型结构的数据中心网络分段路由机制。该机制利用边缘交换机对数据流进行阈值检测以区分大小流,同时为满足其不同业务的QoS保证和网络可扩展性的要求,该文提出一种针对大流的在线最先适应算法。最后,利用Mininet在Fat-tree结构上进行实验仿真验证,仿真结果表明,与传统的ECMP算法和Mahout算法相比,该机制在降低了控制器总开销的同时还提高了网络吞吐率。
[Abstract]:Aiming at the performance bottleneck caused by the low scalability of the current large-scale software defined data center network traffic routing mechanism, In this paper, a tree-oriented segmented routing mechanism for data center networks is proposed, which uses edge switches to detect the threshold of data streams in order to distinguish between large and small flows. At the same time, in order to meet the requirements of QoS guarantee and network extensibility of different services, this paper proposes an online first adaptive algorithm for large flow. Finally, the simulation results on the Fat-tree structure with Mininet are carried out, and the simulation results show that, Compared with the traditional ECMP and Mahout algorithms, the proposed scheme not only reduces the total controller overhead, but also improves the network throughput.
