基于OpenFlow的SDN网络路由算法设计与实现

s a new type of network architecture, the core idea of SDN is the decoupling between the network control plane and data forwarding plane, realize the centralized control of network and provide a flexible network programming interface.The global view of SDN controller can help achieve more efficient routing control and network management strategy.At present, the existing SDN controller technology can achieve data forwarding based on shortest path algorithm, but the deployment of layer three routing still facing some difficulty.In this paper, the SDN routing algorithm was proposed and data forwarding among undirect network was achieved through Ryu controller application. Finally, the experiment on virtual network was carried out by using Mininet platform and verified the system performance.
