| Abstract: | Resilience in SDN control plane is a challenging goal when a single controller is employed. Thus, distributed controllers are deployed to realize a resilient and reliable software defined network. However, such a strategy can not succeed without an efficacious controller-switch assignment scheme. In addition to zero-day assignment, online re-assignment is crucial since due to network failures, the connections between controllers and switches may break off intermittently and impair the network operation. In this paper, we propose a reactive assignment model against network failures using integer linear programming based on load distribution of controllers. We augment our proposal with simulated annealing and random assignment approaches for switch, link and controller failures. The experimental results show that our model gives resilience against network failures and load-awareness is a effective strategy for controller assignment. |
