摘要:

针对SDN网络中多控制器的一致性问题,提出了一种量化的研究方法,为控制层的东西向扩展提供更为精准有效的共享网络视图方法。首先,结合SDN的特性,给出了控制器之间一致性、性能以及可用性的度量指标,建立通用的量化分析模型。其次,针对其中3类典型的一致性问题进行了量化研究,明确了其取得最优值的条件,为一致性参数的配置提供了参考。最后,通过仿真实验对该量化方法进行验证。实验结果表明,该量化方法能够有效提高SDN控制层的性能和可用性。

Abstract:

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.

Key words: SDN, multi-controller, consensus, performance, availability
