摘　　要：网络流量监测是网络管理的重要构成部分,流量监测方法对于评估整个网络的性能至关重要。本文调研分析了当前软件定义网络(Software-Defined Networking,SDN)中的流量监测方法,从以交互为中心和以计算为中心两个角度对流量监测方法进行分类。以交互为中心的方法侧重于交互,由控制器通过南向接口获取数据平面的流量信息。以计算为中心的方法侧重于数据平面,通过交换机内部的复杂计算实时获知网络流量状况。Network traffic monitoring is an important part of network management,and thetraffic monitoring methods play an important role in evaluating the performance of the entire network. This paper investigated and analyzed the traffic monitoring methods in current SDN. And the paper proposed a classification and analyzed the traffic monitoring methods from two different views： interaction-centered and computation-centered. The interaction-centered methods focus on the interaction. In these methods,the controller obtains the traffic information of the data plane via southbound interfaces. The computation-centered methods emphasize the data plane. By adopting complex data analysis process at the data plane,the switches can obtain network traffic in a real-time way.
