基于SDN网络环境感知的智能路由算法

随着网络中海量设备的接入,网络中的环境也日益复杂和多样化,传统的软件定义网络(SDN)路由算法在寻路时没有考虑到网络中的环境因素,如果不考虑这些因素就无法更好地实现对网络节点的实时状态感知,那么也就不能让用户拥有更好的网络体验.针对该问题,结合网络环境信息,提出一种基于SDN网络环境感知的智能路由算法.该算法在时间上进...

Intelligent Routing Algorithm Based on SDN Environment Awareness

With the access of a large number of devices in the network, the environment in the network is becoming more and more complex and diversified. The traditional software-defined network（SDN） routing algorithm does not consider the environmental factors in the network when it finds the way. If these factors are not considered, the real-time status awareness of network nodes cannot be better realized, then users cannot have a better network experience. In response to this problem, combined with network environment information, an intelligent routing algorithm based on SDN network environment awareness is proposed. This algorithm divides two-dimensionally in time, integrates the attribute information of nodes, calculates the probability of encounter between nodes, and then predicts through BP neural network, and finally selects a suitable relay node to complete the data transmission. Simulation experiments have proved the effectiveness of the algorithm in data transmission rate, delay and transmission hops.
