Shuhei Yamamoto, Takuji Tachibana · 2017
In this paper, we propose an optimal resource pool management for sharable VNFs in service chaining. In the proposed method, each resource pool is managed to place each VNF in servers for multiple service chains by solving an optimization problem. In the optimization problem, VNFs that are shared by multiple service chains are determined, and an appropriate amount of resources can be used for each VNF. This optimization problem is solved with genetic algorithm. We evaluate the performance of the proposed method with simulation, and investigate the effectiveness of the proposed method by comparing with other methods. Numerical examples show that our proposed method is effective for managing resource pool in service chaining.
