摘要: 低速拒绝服务攻击对于域间路由系统造成威胁,已有失效恢复算法未能有效解决恢复拓扑计算的时间复杂度高和节点聚合控制等问题,为此,提出一种基于度约束最小生成树的失效恢复算法.通过设计基础迁移子算法和复杂迁移子算法,在满足度约束的条件下根据遭袭路由系统生存拓扑构建新的恢复拓扑,并针对上述两类迁移子算法,分别提出关键点选择子算法,用于判定和计算迁移过程所需的关键节点.理论分析和仿真实验结果证明,该算法生成的恢复拓扑在有效控制节点度的同时,具有较优的性能.

Abstract: In view of the threat of low-rate denial of service attacks on inter-domain routing system,the existing failure recovery methods fail to solve problems including high time complexity and node aggregation control. A failure-recovery algorithm based on degree-constrained minimum spanning tree named degree-constrained minimum spanning tree based failure recovery (DR) is proposed. By designing the Fundamental Transfer sub-algorithm and the complex transfer sub-algorithm,a new recovery topology can be constructed according to the survival topology of the attacked routing system under the condition of given degree constraint. For the above two types of transfer sub-algorithms,two selection sub-algorithms are respectively advanced for the determination and calculation of key nodes. Theoretical analysis and simulation experiments verify that the recovery topology generated by DR has better performance while effectively controlling the node degree.

Key words: inter-domain routing system, failure recovery, degree-constrained minimum spanning tree, time complexity, control of node aggregation
