Abstract

To solve the inconsistency of flow rules between the control plane and data plane caused by SDN data plane software and hardware faults, configuration faults, etc., this paper proposed a P4-based consistency verification mechanism for SDN control-data plane(P4CV). P4CV firstly sent probes with a specific structure to the data plane, and then each P4 switch inserted its runtime information of flow rules in the data plane into the probes. Finally, P4CV adopted the consistency-verification algorithm, based on symbolic execution, to compare the configuration from the control plane and telemetry information from the data plane. The simulation results show that the single path verification time of P4CV is not affected by the network topology and is only linearly related to the number of nodes on the path. In a multipath forwarding scenario, with the same network scale and traffic rules configured, P4CV generates only 0.06‰ of bandwidth overhead and reduces the verification time by 42% compared with the existing scheme.
