软件定义网络(SDN)中的流量工程与动态负载均衡算法优化

Traffic Engineering and Dynamic Load Balancing Algorithm Optimization in Software Defined Networks(SDN)

为了优化软件定义网络(Software Defined Network,SDN)中的流量工程和动态负载均衡算法,建立了基于Open Flow的SDN实验环境,由Open Daylight控制器集中管理。收集了真实网络流量数据,创建了多种流量模式模拟动态负载场景。通过评估指标,全面评估了这些技术在动态负载环境下的性能。经过优化,Link1的带宽利用率降低,有效分散了网络流量,缓解了网络拥塞问题。

In order to optimize the traffic engineering and dynamic load balancing algorithms in Software Defined Network(SDN),an OpenFlow-based SDN experimental environment was established,which was centrally managed by the Open Day light controller.Real network traffic data was collected,and a variety of traffic patterns were created to simulate dynamic load scenarios.The performance of these technologies in a dynamic load environment is comprehensively evaluated through evaluation indicators.After optimization,the bandwidth utilization of Link1 is reduced,effectively dispersing network traffic and alleviating network congestion.
