摘要:

针对软件定义网络(SDN)中不合理的控制器和交换机映射关系导致的控制平面性能低的问题,提出基于联盟博弈的自适应交换机迁移机制。首先,综合考虑控制器资源利用率、控制开销和流建立时间,将交换机迁移问题建模为组合优化问题;然后引入博弈论设计分布式算法,每个控制器独立运行控制逻辑,通过控制器之间协调合作、联盟博弈,实现了依据流量特征的自适应交换机迁移。仿真结果表明,所提机制能更好地适应流量特征,减少约19%的控制流量开销和30%的平均流建立时间,提高了控制器资源利用率。

Abstract:

The problem of poor control plane performance causes in software-defined Networking due to the unreasonable mapping relationship between controllers and switches.To address this issue,an adaptive switch migration mechanism based on coalitional game was proposed.First,comprehensively considering the controller resource utilization,control overhead,and flow establishment time,the switch migration problem was modeled as a combination optimization problem.Then,a game theory was introduced to design a distributed algorithm,where each controller ran control logic independently and implemented coalitional game between controllers to achieve an adaptive switch migration mechanism that adapted to traffic characteristics.The simulation results show that the proposed mechanism can better adapt to the flow characteristics,reduce the control traffic overhead by about 19% and the average flow settling time by 30%,and improve the controller resource utilization.

Key words: software-defined networking, switch migration, coalitional game, resource utilization
