软件定义网络(SDN)通过一个集中控制平面提供网络的整体视图。因此，可以根据有关网络拓扑及其当前状态的全局知识来做出路由决策。由于长时间活动流是适合重路由的候选对象，因此它们的检测对于基于流的有效交通管理至关重要。本文提出了SDN网络中大象检测的ZOOM算法。为此，Zoom遵循一种非常轻量级的方法，该方法只使用OpenFlow交换机实现的数据包计数器，因此不需要任何额外的硬件。通过利用OpenFlow交换机的这一功能，ZOOM允许轻量级且经济高效的大象检测。
Software Defined Networking (SDN) offers a holistic view of the network through a centralized control plane. Consequently, routing decisions can be made based on global knowledge about the network topology as well as its current state. As long living flows are suitable candidates for rerouting, their detection is crucial for efficient flow based traffic management. This work proposes the ZOOM algorithm for elephant detection in SDN networks. To this end, ZOOM follows a very lightweight approach that only uses packet counters implemented by OpenFlow switches and thus does not require any additional hardware. By exploiting this feature of OpenFlow switches, ZOOM allows lightweight and cost-effective elephant detection.
