基于OpenFlow的可编程终端设计与实现

摘要

With the development of the Internet and network access technology, user client devices equipped with multiple network interfaces have been widespread, multiple interfaces simultaneously access the network, will establish multiple connections. In addition to the existing multi-interface client to modify the kernel, there are no kinds of lfexible approach to managing multiple connections. OpenFlow technology has attracted more and more attention to the network researchers, in this paper, OpenFlow technology will be applied to the client, compatible with existing network protocol stack at the same time, make the client programmable, and provides a methods to manage multiple connections on the programmable client. We also develop a connection management module based on the client controller, and successfully implemented on Linux systems.%随着互联网和网络接入技术的不断发展，终端配备多个网络接口已经十分普遍，多个接口同时接入网络，会建立多条连接，现有的多接口终端除了修改内核之外，没有一种灵活的方法管理多个连接。OpenFlow技术已经吸引了越来越多网络研究人员的关注，本文中将OpenFlow技术应用到终端，兼容现有的网络协议栈的同时，使终端具有可编程性，并提供了一种在可编程终端上管理多连接的方法，基于终端控制器开发实现了连接管理组件，并且在Linux系统上成功实现。
