摘　　要：在可信可控网络中利用多个控制节点对AS进行联合控制,容易造成多个控制节点在网络控制过程中持有的AS视图不一致问题。针对该问题,在可信可控网络模型的基础上提出了基于选举算法的AS内一致性视图构建机制,该机制首先基于选举算法选举出主控制节点,然后主控制节点根据AS内各个控制节点的负载,将视图构建任务分配给负载最低的控制节点负责构建视图,并利用主控制节点的时间对生成的视图的版本进行界定,从而避免了多个控制节点独自构建视图造成的视图混乱问题。仿真实验的结果表明,所提出的一致性视图构建机制具有良好的性能。Multiple control nodes are used to control an AS coordinately in trustworthy and controllable networks,thus easily resulting in the problem of inconsistent AS views of different control nodes.To solve this problem,based on the trustworthy and controllable network model,an election algorithm based consistent view construction mechanism is proposed.Firstly,an election algorithm is used to generate a primary control node.Secondly,according to the loads of the control nodes in an AS,the primary control node assigns the view construction tasks to the control node with the lowest load.Thirdly,the version of the generated view is defined by the time of the primary control node.The mechanism avoids the problem of inconsistent views due to the individual view construction of different control nodes.Besides,the simulation experiment results show that the proposal has good performance.
