摘要
具有定义特征的软件定义网络(SDN)如“数据与控制平面的分离”和“通过决策集中网络控制”显着简化了网络的管理。目前,用于动态测量网络流量的主动监控技术会在网络中引入额外的开销,而被动方法在流量测量方面缺乏准确性。为了克服以上困难,本文提出了一种新的实用的解决方案,为SDN中的流量测量系统提供准确的实时流量矩阵。该解决方案基于固定测量设计被作为测量细粒度的监视器。实验表明,该方案可以在不影响精度的情况下实现显着的减少开销。
Software⁃Defined Networks(SDN)with defined features such as"separation of data and control planes"and"network control through decision⁃making"significantly simplify network management.Currently,active monitoring techniques for dynamically measuring network traffic introduce additional overhead into the network,while passive methods lack accuracy in traffic measurement.In order to overcome the above difficulties,this paper proposes a new practical solution to provide an accurate real⁃time traffic matrix for the flow measurement system in SDN.The solution is based on a fixed measurement design that is used as a monitor for fine⁃grained measurements.Experiments show that this scheme can achieve significant cost reduction without affecting accuracy.
