A simple scheme for distributed deployment of controllers of SDN
Shunxin Qin, Yijie Shi · 2017
In order to improve the overall performance of the software defined network, a simple deployment scheme is proposed for the controller deployment problem. Firstly, the number of controllers needed in the network is analyzed, and then the NMFRS algorithm is used to select the deployment location of the controller. Finally, the existing SOA service framework is used to realize the distributed collaboration among controllers. The experimental results show that NMFRS reduces the hops from switches to the controller, and at the same time, the existing SOA service framework can realize the distributed cooperation of controllers easily.
