本文基于软件定义网络(software defined betworking,SDN)概念,利用OpenFlow技术设计并实现了一种新颖的IP融合切换技术.该技术基于当前网络状况对IP数据流的下一跳转发方式进行灵活选择,在IPv4与IPv6域之间完成高效的动态切换.因此,它可以在IPv4与IPv6共存的异构网络中实现服务质量(QoS)感知的动态流量调控.本文对OpenFlow进行了适当的拓展,并完成了OpenFlow系统设计以实现IP融合切换技术,同时提出了面向多业务的动态流量调控算法,并利用真实的网络交换机和服务器搭建了实验平台,验证了系统和算法的性能.视频和文件同步传输实验的结果证明了所提出的IP融合切换技术在实现动态流量调控方面的优越性.
Based on the concept of software defined betworking (SDN), this paper designs and implements a novel IP fusion switching technology by using OpenFlow technology, which flexibly chooses the next hop forwarding mode of IP data flows based on the current network conditions , Which implements efficient dynamic switching between IPv4 and IPv6 domains and therefore enables QoS-aware dynamic traffic control in heterogeneous networks co-existing with IPv4 and IPv6.This paper extends OpenFlow appropriately, Completed the design of OpenFlow system to realize IP fusion switching technology, and proposed a dynamic traffic regulation algorithm for multi-service at the same time, and built an experiment platform by using real network switches and servers to verify the performance of the system and algorithm. Video and file synchronization transmission The experimental results demonstrate the superiority of the proposed IP fusion handover technique in dynamic traffic regulation.
