基于SDN的web访问控制应用的实现

摘要

软件定义网络（Software Defined Network，SDN）及其主流协议OpenFlow通过解耦控制平面与数据平面，提供应用平面编程接口，给数据中心提供了更为方便的网络设备管理手段。本文基于OpenDayLight（ODL）控制器北向接口，在一个对外提供web服务的网络中，实现了控制用户访问某一TCP/IP协议端口的功能，并能使管理员进行实时配置。%Software Defined Network(SDN) and it's main protocol OpenFlow provide better network management for data centers by decoupling the control plane and the data plane and providing application programming interfaces.In this paper, Based on northband interface of OpenDayLight (ODL), we achieve control users access to a port of a proto-col of TCP/IP, and enables administrators to real-time configuration.
