中文摘要：
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。从分析冲突类型入手，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。
英文摘要：
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 miswirings;Improved method to some extent enhances the performance of conflict detection method to achieve the desired effect.
