Abstract
This work presents a model to solve the switch migration problem in software-defined networking. This model is formulated as a mixed-integer linear programming, and compared against the static mapping approach. Two scenarios of homogeneous and heterogeneous controllers are evaluated. The experimental results show that the dynamic mapping enabled by the proposed model can enhance the controllers’ utilization by for homogeneous scenario and for heterogeneous scenario, while maintaining a low control plane overhead.
