Abstract

The invention discloses a service quality guarantee system and method based on an SDN network. The system comprises: an SDN switch which is used for querying whether a flow table entry corresponding to the data packet exists in an Open Flow flow table or not after receiving the data packet, and forwarding the data packet to a target path indicated by the flow table entry if the flow table entry corresponding to the data packet exists in the Open Flow table; and an SDN controller which is used for setting the path bandwidth of the target path and the queue priority of the port of each node passing through the target path according to the flow of the application type corresponding to the data packet when the flow table entry corresponding to the data packet exists in the Open Flow flow table. According to the system and the method provided by the invention, the QoS guarantee efficiency is improved, the system and the method are easy to implement, and meanwhile, the end-to-end quality service is accurately guaranteed.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to an SDN network-based service quality guarantee system and method. Background technique [0002] Quality of Service (QoS) means that the network can use various related technologies. It can transmit data according to the priority based on the data type, reserve network bandwidth for specific network communication, and provide better service capabilities for specified network services to achieve A technology for normal communication between data, which can be measured by indicators such as transmission delay, bandwidth, and packet loss rate jitter. [0003] At present, there are three main models for QoS-related research: Best-Effort Services Model, Integrated Services Model, and Differentiated Services Model. Best-Effort is a relatively simple service model, which is the default service model of the network. Under this model, packets can be sent as much as p...
