Problems solved by technology

[0003] However, in the process of using the SDN network architecture, the data plane in the network architecture will be affected to varying degrees. The inconsistency between the control plane and the data plane will lead to the loss of part of the transmitted data or the temporary stagnation of the system. In serious cases, there may be malicious network intrusion in the SDN network, and there are potential security risks in the network.

Abstract

The application discloses a method for judging the consistency of SDN network rules, including: obtaining the transmission rules of the switch, performing a transmission path restoration operation according to all the transmission rules, and obtaining the actual transmission path; obtaining the expected transmission path according to the flow table in the SDN network. Transmission path; performing matching processing on the actual transmission path and the expected transmission path; when the matching processing passes, determine that the SDN network rule is in a consistent state; when the matching processing fails, determine the SDN network rule into an inconsistent state. The actual transmission path of the data is obtained by restoring the directly obtained switch transmission rules, and then matching with the expected transmission path obtained by the flow table to obtain the consistency judgment result. The judgment steps are simple and easy to implement. The application also discloses a device for judging the consistency of SDN network rules, a server and a computer-readable storage medium, which have the above beneficial effects.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to a method for judging consistency of SDN network rules, a device for judging consistency, a server, and a computer-readable storage medium. Background technique [0002] With the continuous development of network technology, in order to rationally allocate network resources and improve network data transmission efficiency, the prior art provides a technical solution of a software-defined (SDN Software Defined Network) framework. The network framework divides the network into a data plane and a control plane. The data plane is mainly responsible for data forwarding, while the control plane is responsible for formulating corresponding forwarding strategies. This architecture of separation of control and forwarding frees the control layer from dependence on network devices and provides flexible and convenient programmability. At the same time, when creating a virtual...
