通过赋予软件定义网络分布式控制平面拜占庭属性可以有效提高其安全性。在实现拜占庭属性过程中,控制器部署的数量、位置,以及交换机与控制器之间的连接关系会直接影响全局网络关键性能指标。为此,提出了一种考虑拜占庭属性的 SDN 安全控制器多目标优化部署方案。首先,构建了综合考量交互时延、同步时延、负载差异程度和控制器部署数量等优化指标的拜占庭控制器部署问题(MOSBCPP)模型;然后,针对该模型个性化设计了包括控制器部署策略初始化函数、变异函数,快速非支配排序函数及精英策略选择函数等在内的NASG-II求解算法。相关仿真结果表明,该部署方案能够在有效降低交互时延、同步时延、负载差异程度和控制器部署数量等性能指标的同时提高控制平面安全性。
By giving the software defined network distributed control plane Byzantine attributes
its security can be effectively improved.In the process of realizing Byzantine attributes
the number and location of controllers
and the connection relationship between switches and controllers can directly affect the key network performance.Therefore
a controller multi-objective optimization placement strategy for SDN security controllers considering Byzantine attributes was proposed.Firstly
a Byzantine controller placement problem (MOSBCPP) model that comprehensively considered interaction delay
synchronization delay
load difference and the number of controllers was constructed.Then
a solution algorithm based on NASG-II was designed for this model
which included the initialization function
the mutation function
the fast non-dominated sorting function and the elite strategy selection function.Simulation results show that this strategy can effectively reduce interaction delay
synchronization delay
load difference and the number of controllers
while improving control plane security.
