摘要

针对如何保护控制器，尤其是骨干控制器免受安全威胁与攻击，提高 SDN 控制平面的安全性，提出一种基于最小代价路径的交换机迁移算法。在迁移模型中加入负载预测模块，预测模块执行控制器负载预测算法，得到负载预测矩阵，然后根据负载预测矩阵确定迁出、目标控制器集合。利用改进的迪杰斯特拉算法确定最小代价路径，根据控制器的负载状态和待迁移交换机的流量优先级，在最小代价路径中确定最优迁移交换机集合，同时针对迁移过程中可能产生的孤立节点问题给出了解决方案。实验结果表明，所提算法确定的迁移触发时机、迁出控制器和目标控制器更加合理，减少了迁移次数和代价，增强了控制器的安全性，提高了控制器性能。

Abstract

In order to protect the controller

especially the controller in backbone network

from security threats and attacks

improve the security of the software-defined network (SDN) control plane

a switch migration algorithm based on minimum cost path was proposed.A load prediction module was added to the migration model

which executed a controller load prediction algorithm to obtain a load prediction matrix

and then a migration-target controller set was determined according to the load prediction matrix.The improved Dijkstra algorithm was used to determine the minimum cost path.According to the load state of the controller and the traffic priority of the switch to be migrated

the optimal migration switch set was determined.The problem of isolated nodes was solved that may occur during the migration process.The experimental results show that the migration timing of the algorithm is more reasonable

the selection of the migration controller and the target controller is more reasonable

the load balancing of the control plane is realized

the number of migrations and cost are reduced

and the performance of the controller is improved.
