SDN-based backbone network flow granularity adjustment system and method

Abstract

The invention discloses an SDN-based backbone network flow granularity adjustment system and method, the system comprises an SDN controller, a service flow scheduling application and a white board physical device, the SDN controller and the white board physical device are connected and can access each other through network connection, the service flow scheduling application is connected with the SDN controller, the service flow scheduling application and the white board physical device are mutually accessed through the SDN controller, the SDN controller, the service flow scheduling application and the white board physical device form a network, and the SDN controller issues corresponding OpenFlow flow table rules to the white board physical device according to different data packets. The white board physical device sends the data to different devices and links for forwarding according to an OpenFlow flow table rule.

Description

technical field [0001] The invention discloses a traffic granularity adjustment method, in particular to an SDN-based backbone network traffic granularity adjustment system and method, belonging to the technical field of computer networks. Background technique [0002] The main function of the backbone network is to use high-speed links to connect multiple provinces, cities or regions to achieve high-speed data packet forwarding. The backbone network is a large-scale network structure, generally a wide area network, and its range can reach thousands of kilometers. Our country has 9 major backbone networks to complete the interconnection and intercommunication of all provinces and cities across the country, as well as information exchange with other countries. With the rapid development of the Internet, different types of data access between different areas of the backbone network are becoming more and more extensive. The backbone network is playing an increasingly importan...
