Abstract:

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.
