摘　　要：软件定义网络(SDN)通过将控制平面与数据平面分离并使网络可编程来改变网络的管理方式。控制器是SDN网络的关键组成部分。对于诸如DHCP中继功能、动态路由功能等传统网络功能,目前已存在成熟的第三方网络组件。基于能够更便捷地开发面向SDN的传统网络应用,设计与实现一种通用的传统网络功能集成方法,该方法通过将底层网络流量同步给第三方网络组件,由第三方网络组件完成核心的网络功能。文中基于ONOS控制器利用该集成方法开发了一款通用的传统网络应用,并通过集成DHCP Relay功能的实验完成了对该集成方法的功能性验证。Software Defined Network(SDN) changes the management mode of the network by separating the control plane from the data plane and making the network programmable.The controller is a key component of SDN network.There are already mature third-party network components which implement the traditional network functions such as DHCP Relay and dynamic routing.Based on the purpose of more conveniently developing traditional SDN oriented network applications,a general traditional network function integration method is designed and implemented.This method synchronizes the underlying network traffic to the third-party network component which completes the core network functions.In this paper,a general traditional network application is developed based on the ONOS using this integration method,and the functional verification of this integration method is completed through the experiment of integrating the function of DHCP Relay.
