| Summary: | For the problem of multi-controller’s consensus in SDN,a quantitative approach was proposed,which provided a more accurate and effective method of sharing network view for the control layer's east-west extension.Firstly,the metrics of consensus,performance and availability between the controllers with the feature of SDN was provided,establishing the common model for quantitative research.Secondly,for the three typical questions in the research of multi-controller’s consensus,the condition to achieve its optimal value was explicated,which provided a reference for the configuration of consensus.Finally,to verify the validity of the quantitative approach by simulation,experimental results show that this approach can improve the performance and availability of the control layer in SDN effectively. |
