数据中心网络(DCN)地址配置过程中可能存在配置冲突,利用图同构思想进行冲突检测是一种有效而且可行的方法.从分析冲突类型人手,提出了基于子图同构的冲突检测方法,并对O2算法中基于SPLD产生的关键对的计算进行优化,减少潜在误报；在子图同构的x跳数选择上,探讨给出适当的跳数大小,利用二分法寻找同构子图；对不引起度改变的错误连线故障,通过记录两端节点的方式记录错误连线；改进后的方法一定程度上提升了冲突检测方法的性能,达到了预期效果.%Data center network address configuration may exist configuration conflicts,it is an effective and feasible method to use graph isomorphism ideological for conflict detection. Analysis of the type of conflict first, proposed a method of detection conflict based on subgraph isomorphism,and optimized the O2 algorithm that key generated based on SPLD,reduced the potential for false positives;Subgraph isomorphism in the number of hops the choice of x, give the appropriate number of hops of size, use dichotomy looking for subgraph isomorphism; On the degree of change does not cause the error connection failed, the way by recording both ends of the nodes record the mis wirings; Improved method to some extent enhances the performance of conflict detection method to achieve the desired effect.
