AI Technical Summary

Technical Problem

In existing public cloud scenarios, traffic monitoring methods rely on VXLAN technology, need to deploy special mirror network elements, increase hardware resource usage and management and maintenance costs, and have high requirements for situational perceptrons, and need to have VXLAN decapsulation capabilities to limit their applicability.

Method used

By receiving the Openflow flow table and group table sent by the SDN controller on the host where the virtual machine is located, network traffic mirroring and encapsulation are performed, and the encapsulated packets are directly forwarded to the situational perceptron host to avoid forwarding and processing in the intermediate links.

Benefits of technology

It supports multiple network types of traffic monitoring without occupancy of additional hardware resources, improves the efficiency and accuracy of traffic monitoring, and reduces system complexity and cost.

Abstract

The embodiment of the invention provides a network traffic processing method and electronic equipment, relates to the technical field of cloud scene traffic monitoring, and aims to improve the efficiency and accuracy of traffic monitoring and reduce hardware and maintenance cost. The method comprises the following steps: receiving a first Openflow table and a group table issued by an SDN controller; mirroring to-be-monitored network traffic based on the first Openflow table to obtain a target message, and copying the target message to the operation and maintenance group table based on the group table; performing inner layer and outer layer packaging on the target message in the operation and maintenance group table according to the global label of the target situation sensor carried by the first Openflow table to obtain a packaged message; and forwarding the encapsulated message to a situation awareness host machine corresponding to the target situation awareness, so that the situation awareness host machine decapsulates the encapsulated message to obtain a target message, and sending the target message to the target situation awareness for traffic monitoring and analysis.
