摘要
随着云计算和大数据时代的到来,网络安全问题的着眼点已经逐步转移到全局化、大流量以及多样性等方面。SDN框架作为目前逐步兴起的新型网络架构,将数据层面与控制层面分离的思想给网络安全带来全新的思路与挑战。基于SDN框架提出一种路由调整方法,该方法基于AHP对所有涉及源节点和目的节点的安全因子进行评分,将分值最高的路由作为控制器所采用的最佳安全路由,从而达到对网络流进行安全导向的目的。
With the advent of cloud computing and big data era,the focus of network security issues has gradually shifted to global,high traffic and diversity.As a new type of network architecture that is gradually emerging,the SDN framework brings new ideas and challenges to network security by separating the data layer from the control layer.A route adjustment method based on SDN framework was proposed.This method is based on AHP to score all the security factors involved in the source node,and the route with the highest score is used as the best security route adopted by the controller,so as to achieve the network flow.The purpose of security orientation.
