摘要 网络的管理与监测是网络领域的重要话题,这一领域的相关技术通常也称为网络测量(network measurement).网络重要流检测(network heavy hitter detection)是网络测量的一项关键技术,也是研究对象.重要流指占用网络资源(如带宽或发送的数据包数量)超过某一给定标准的流,检测重要流有助于快速识别网络异常,提升网络运行效率,但链路的高速化为其实现带来了挑战.按出现时间顺序,可将重要流检测方法划分为两大类:基于传统网络框架的和基于软件定义网络(SDN)框架的.围绕网络重要流检测相关的框架与算法,系统地总结其发展过程与研究现状,并尝试给出其未来可能的发展方向. Network management and monitoring are crucial topics in the network field,with the technologies used to achieve this being referred to as network measurement.In particular,network heavy hitter detection is an important technique of network measurement,and it is analyzed in this study.Heavy hitters are flows that exceed an established threshold in terms of occupied network resources(bandwidth or the number of packets transmitted).Detecting heavy hitters can contribute to quick anomaly detection and more efficient network operation.However,the implementation of heavy hitter detection is impacted by high-speed links.Traditional methods and software defined network(SDN)-based methods are two categories of heavy hitter detection methods that have been developed over time.This study reviews the related frameworks and algorithms,systematically summarizes the development and current status,and finally tries to predict future research directions of network heavy hitter detection.
