Abstract

The invention relates to a method and a system for controlling and guaranteeing the service quality of a software defined network. The method comprises the following steps that: an SDN switch acquiresa network state and reports the network state; the SDN controller constructs a global network topology according to the network state; the SDN controller sets a flow parameter of each application according to the performance requirement of each application and the type; the SDN controller generates an OpenFlow flow table according to the flow parameters of each application and transmits the OpenFlow flow table to the SDN switch; and the SDN switch receives the data packet, queries the OpenFlow flow table, forwards the data packet according to the OpenFlow flow table when a query result exists, and reports the data packet to the SDN controller when the query result does not exist. Advantages of the SDN are fully utilized, a plurality of queues are arranged on a port to correspond to different services, performance requirements of different application types can be met, and bottom hardware is controlled in a centralized manner, so that service quality control guarantee is realized, andthe method is particularly suitable for data network visual flow scheduling.

Description

technical field [0001] This application relates to the field of service quality assurance, in particular to a method and system for software-defined network service quality control assurance based on application classification. Background technique [0002] Quality of Service (QoS), also known as quality of service assurance, 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 specific network A technology that enables businesses to provide better service capabilities to achieve normal communication between data, which can be measured by indicators such as transmission delay, bandwidth, and packet loss rate jitter. [0003] Software Defined Network (SDN) has emerged. The design concept of SDN network is to separate the logical control level of network equipment from the data forwarding level, and then provide an interface t...
