| Abstract(in English) | Network services provisioning with Service Function Chaining(SFC) consists of various controls such as Virtual Network Function(VNF) placement/resource allocation and traffic flow routing, which are executed dynamically. These controls take time to execute from start to finish, and the execution time varies depending on the type of control. The control with long execution time may lead to prolonged QoS degradation. In order to optimize the network performance, a control method should execute the controls taking into account the difference in execution time. While existing control methods don't focus on the difference. In this paper, we propose a control scheduling method that takes into account the difference and minimizes the duration of delay degradation. The proposed method uses stochastic search based on the load degree of VNF instances to obtain a sub-optimal solution with small computational complexity. Simulation evaluations show that the proposed method minimizes the delay degradation compared to the conventional method. |
