Abstract:

Introducing multiple controllers to software defined network so that dynamically altering the mapping relationship between controller and the underlying network is an effective method to ease the security threats in control plane.However,little previous work has been done to investigate the economical time in dynamic-scheduling controllers.Firstly,the importance of scheduling-time in dynamic control plane based on security in SDN and dynamic control plane was introduced.Further,this problem was modeled as a renewal reward process and an optimal algorithm in deciding the right time to schedule was proposed.In our experiments,Simulations based on real network attack dataset are conducted and it demonstrate that proposed algorithm outperforms fixed-cycle algorithms and random algorithm.

Key words: software defined network, network security, controller
