Abstract

The present disclosure relates to a flow control method, device, system and SDN controller, and relates to the technical field of communication. The disclosed method includes: the software-defined network SDN controller obtains the domain name system DNS message; the SDN controller parses the DNS message to obtain the path information from the terminal to the application server; the application server is located in the edge data center; The path information of the server generates a flow table; the SDN controller sends the flow table to the first switch corresponding to the distribution device and the application server, so that the distribution device and the first switch transmit the traffic that the terminal interacts with the application server through the tunnel. The solution of the present disclosure adopts the dynamic flow table of the SDN controller to control the first switch corresponding to the offloading device and the application server, realizes directing the traffic of the terminal to the application server in the edge data center, uses the edge data center to provide services for the terminal, and realizes application access optimization to improve access efficiency.

Description

technical field [0001] The present disclosure relates to the technical field of communications, and in particular to a flow control method, device, system and SDN controller. Background technique [0002] Recently, based on the CO (Central Office, telephone end office) reconstruction concept, the industry has gradually begun to develop an architecture that introduces edge data centers at the edge of the MAN to provide users with optimized services. [0003] Although the research direction of CO reconstruction and the introduction of edge data centers have been determined, there is currently no specific plan on how to direct terminal access traffic to edge data centers. Contents of the invention [0004] A technical problem to be solved in the present disclosure is: how to direct terminal access traffic to an edge data center. [0005] According to some embodiments of the present disclosure, a flow control method is provided, including: a software-defined network SDN contr...
