Problems solved by technology

[0006] When the inventor researched the SDN modular programming method, he found that due to the complexity of SDN rules and the diversity of policy deployment (strategies can manage the network in a variety of ways), inappropriate configuration of a rule of a single policy may cause It affects the normal operation of other strategies (abnormal function), and at the same time, a redundant rule of a single strategy may cause hundreds or thousands of redundant rules (abnormal efficiency) in the final deployment, which directly affects the operating efficiency of the system
However, the existing detection methods are difficult to fully detect these abnormalities in function and efficiency
[0007] Therefore, how to define the abnormalities of SDN policies and how to quickly detect and locate SDN abnormal rules is a huge challenge.

Abstract

The present invention relates to a detection method, system, device and storage medium for SDN network policy anomalies, wherein the detection method includes: step 100, acquiring one or more of the policies in the SDN network, and respectively The above-mentioned strategies are used for internal abnormality detection. When the obtained strategy is one or an internal abnormality is detected in the strategy, the result is returned directly. When there are multiple obtained strategies and no internal abnormality is detected, step 200 is performed. ; Step 200, judging the collaborative control relationship between multiple strategies and performing external anomaly detection to obtain the detection result. The invention can ensure that in the programming process of the software-defined network (SDN), the function and efficiency abnormalities within and between SDN strategies can be quickly discovered and located, and can be fed back to network programmers in time.

Description

technical field [0001] The present invention relates to the technical field of computer software-defined network (SDN), in particular to a method, system, device and storage medium for software-defined network policy anomaly detection. Background technique [0002] After decades of development, the Internet has become the information infrastructure of modern society. However, compared with the vigorous development of the computer industry, the innovation of the network is relatively very slow. The fundamental reason is that the control logic of the network is solidified in the distributed network equipment, while the current network equipment is relatively closed and rigid. For this reason, Software-Defined Networking (SDN: Software-Defined Networking) emerged as the times require, which adopts an open system architecture in which the data plane and the control plane are separated, and manages and controls the entire network through a centralized controller. [0003] In or...
