Abstract：The current network architecture has scalability, security, stability problems. SDN network, because of its separation of the control plane and the data plane of network, programmable features, can effectively solve the current network problems, and has been widespread concern. Because the SDN network configuration does not have the atomicity, which affects the efficiency of SDN network management, the consistency of control logic is one of the main problems in SDN research. This paper makes research on the consistency of the control logic during the process of SDN network update, and puts forward a consistency algorithm based on classifier and label by classifying switches and marking packets. The goal is to solve the SDN network configuration problem, guarantee per-packet consistency. And prove the correctness of the algorithm through logic verification. Finally, this paper makes comparison with other algorithms to prove the efficiency of the algorithm.
