摘　　要：提出基于配置的流表更新一致性方案,在保证更新一致性的同时,通过建立的规则和流表配置以及对算法的推算,发现并获得新规则之间的相关性,以此对流表进行更新;采用线性规划的方法对最大化流量满足度问题的描述进行建模,对已经释放策略规则计算出最好的分配方法。实验结果表明,与相关研究相比,该方法在更新时延、降低控制负载、优化流量占用三个方面表现较好。This paper proposes a configuration-based consistent flow update algorithm.Under the prerequisite of ensuring the consistence of update process,it finds and obtains the correlation between the new rules through rules establishment,flow configuration and algorithm calculation as well,so as to achieve flow update.In addition,linear programming is adopted to model maximized traffic satisfaction description,and calculate the best allocation method for rules.As the result manifests and compared with the related research,the algorithm can reduce the time delay and work load,and maximize traffic satisfaction.
