摘　　要：可信可控网络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。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。另外,仿真实验结果表明,提出的一致性视图构建机制具有良好的性能。Multi control nodes are used to control an AS coordinately in Trustworthy and Controllable Network. The views of different control nodes may be inconsistent. To solve this problem, we proposed a consistent view construction mechanism, in which a selection algorithm is used to generate a primary control node first, and then the primary control node is responsible for organizing other control nodes to build consistent view for all view requests. This mechanism a- voids the problem that the views of different control nodes are inconsistent. Besides, the simulation experiment verifies that the mechanism proposed in this paper has better performance than prior view construction method in both time cost and communication overheads.
