SDN中基于可靠性评估的多控制器均衡部署策略
Multi-controller balancing deployment strategy based on reliability evaluation in SDN
摘要
Abstract
The control plane has low reliability and controller loads were unbalanced in distributed software defined net-works, and a multi-controller balancing deployment strategy based on reliability evaluation was proposed. Firstly, node reliability was evaluated by weighting node efficiency and path quality, optimizing the controller location with balancing factor. Then based on improved k-center clustering, the redundant functions was introduced and the switch allocation was completed according to node attractiveness degree and controller load balancing rate, achieving a reasonable SDN sub-domain planning.The simulations show that compared with the existing strategy the number of required controllers is reduced by an average of 22.1%. The control plane elasticity is enhanced, and the controller load balancing performance has been improved significantly.关键词
