Traffic scheduling system and method based on VXLAN and OpenFlow

Abstract

The invention discloses a traffic scheduling system and method based on VXLAN and OpenFlow, and the system comprises an SDN controller, a terminal, and a white board physical device, the SDN controller and the white board physical device are connected and can access each other through a network, the white board physical device is connected with the terminal, and the terminal is connected with the terminal. The terminal can achieve mutual access with the SDN controller through the white board physical device, one or more VXLAN tunnels are established on a source destination node of a service, the SDN controller imports different service data into the different VXLAN tunnels through an OpenFlow flow table according to requirements for bandwidth, time delay and packet loss, and differentiated forwarding of the service is achieved.

Description

technical field [0001] The invention discloses a flow scheduling method, in particular a flow scheduling system and method based on VXLAN and OpenFlow, belonging to the technical field of computer networks. Background technique [0002] The number of services in the network is growing explosively, and the requirements for launching and updating iterations of new services are accelerated. Traffic scheduling technology is an important technology for network traffic control and an important means to ensure the normal operation of network services. In the existing technology, the traditional network is a distributed architecture, and the control rights are distributed among various network devices, lacking a centralized unified management platform, and manual configuration is cumbersome. OpenFlow is a southbound protocol for SDN. The SDN controller can use the OpenFlow flow table to specify device packet forwarding. The white label of traditional equipment manufacturers must ena...

AI Technical Summary

Problems solved by technology

There are the following problems in using the OpenFlow protocol to control network traffic in the white-box equipment of traditional equipment manufacturers. When the STP protocol is enabled on the equipment, any source-destination node in the SDN network has one and only one reachable path, and the SDN controller cannot use The OpenFlow protocol plays a role in selecting different service links for different services. At the same time, when the path is blocked, the custom service link cannot be used as a backup link; the device closes the STP protocol and there is a loop in the SDN network topology, and the OpenFlow flow table is used to implement Traffic scheduling, the device will have a network storm

It can be seen that it is difficult for traditional equipment manufacturers to use OpenFlow flow table as a flow control technology to provide high availability, designated service links, and redundant paths for services in SDN networks.
