论文摘要
软件定义的网络（SDN）是一种旨在使网络快速，灵活的体系结构。 SDN的目标是通过使服务提供商以及企业快速响应不断变化的业务需求来改善网络控制。在SDN中，管理员可以从集中式控制控制台塑造流量，而无需修改属于网络的任何单个开关。集中式的SDN控制器指示开关在需要的任何地方提供网络服务，而与服务器和设备之间的特定连接无关。这种方法是从传统网络体系结构的转变，在该架构中，各个网络设备根据其配置的路由表做出流量决策。在本文中，我使用Floodlight控制器构建并测试了SDN负载平衡器和防火墙模块。
Software-defined networking (SDN) is an architecture that aims to make networks fast and flexible. SDN's goal is to improve network control by enabling service providers as well as enterprises to respond quickly to changing business needs. In SDN, the administrator can shape traffic from a centralized control console without having to modify any of the individual switches belonging to the network. The SDN controller which is centralized directs the switches to deliver network services wherever they are needed, irrespective of the specific connections between a server and devices. This methodology is a shift from traditional network architecture, in which individual network devices make traffic decisions based on their configured routing tables. In this paper, I built and tested an SDN load balancer and firewall module using the Floodlight controller.
