摘要:

多控制器软件定义网络(SDN)中交换机迁移策略单一,造成迁移效率低且多次迁移。为此,提出一种基于改进型拍卖的交换机迁移机制PASMM,将交换机的迁移问题优化成为控制器剩余资源的拍卖问题,通过提高处于供不应求状态的控制器资源的交易价格,完成拍卖过程,实现控制器和交换机的重新部署,提高网络效益。仿真实验表明,与典型的交换机迁移策略相比,PASMM达到了较好的控制器负载均衡,PACKET_IN消息的响应时间减少了约13.5%,同时随着交换机流请求的增大,PASMM的迁移时间最少。

Abstract:

In multi-controller Software Defined Network (SDN), since the existed switch migration strategies always have low efficiency and need to migrate many times which only consider single migration factor, a mechanism of switches migration based on progressive auction named PASMM (Progressive Auction based Switches Migration Mechanism) was proposed. To improve network benefit, the switch migration problem was optimized by auctioning controllers' remaining resources in the mechanism. By increasing the trading price of the over-demanded controllers' resources, PASMM completed the auction and redeployed the controllers and switches. The simulation results show that, compared with some typical switch migration policies, PASMM achieves good load balancing of controllers, reduces the response time of the PACKET_IN messages by an average of 13.5%, and spends the least migration time with the increasing of switches flow requests.

Key words: auction, Software-Defined Network (SDN), multi-controller, load balance
