摘要
为解决传统网络路由转发体系缺乏灵活性的问题,提出了OpenTDR开放式架构方案。该方案通过集成二维路由和软件定义网络(software defined network,SDN)技术,可在不同时间段实施不同的流量均衡和节能机制。实验结果表明,由一维升级至二维的路由转发方式,配合SDN的集中式网络规划,可明显增强网络(尤其是广域网)的流量调度与服务质量控制的灵活性,达到流量均衡与节约能耗的目的。另外,二维路由机制兼容传统路由,为基于传统网络的SDN改造提供了可行的过渡方案。
In order to improve the lack of flexibility in traditional network routing and forwarding systems,an open architecture OpenTDR scheme was proposed.This solution combined two-dimensional routing and software defined network(SDN),which could implement different traffic balancing mechanisms and energy saving mechanisms in different time periods.The experimental results show that upgrading from one-dimensional to two-dimensional routing and forwarding mode,combined with the centralized global planning approach of SDN,can make the flow control and service quality of networks(especially wide area networks)more flexible,and achieve the goal of traffic balance and save energy consumption.On the other hand,two-dimensional routing can be compatible with traditional routing,which also provides a suitable transitional solution for SDN transformation based on traditional networks.
