Problems solved by technology

[0002] Traditional traffic scheduling cannot dynamically configure routing policies according to traffic changes
Usually, manual configuration of BGP (Border Gateway Protocol, Border Gateway Protocol) routing policy is required, which requires routers in the entire network to operate one by one, which is a heavy workload and prone to errors.

Abstract

The invention discloses a traffic scheduling method and system, and a software defined network controller. The method comprises the following steps: a traffic monitoring network management module monitors the exit traffic of a metropolitan area network, and inputs traffic monitoring data to the software defined network controller; the software defined network controller determines a traffic adjustment and optimization command according to the traffic monitoring data; the software defined network controller sends a border gateway protocol traffic specification message to a controlled device, wherein the border gateway protocol traffic specification message comprises the traffic adjustment and optimization command; the controlled device forwards the border gateway protocol traffic specification message to other core devices other than the controlled device in a backbone network; and the core devices schedule the traffic to new paths according to the traffic adjustment and optimization command so as to achieve traffic adjustment and optimization. According to the traffic scheduling method disclosed by the invention, real-time dynamic adjustment and optimization of traffic can be achieved through the SDN centralized architecture, thereby improving the overall utilization rate of the network; and the BGP flowspec information can be flexibly spread on the network, thereby reducing the huge workload of one by one configuration.

Description

technical field [0001] The invention relates to the field of data communication, in particular to a flow scheduling method and system, and a software-defined network controller. Background technique [0002] Traditional traffic scheduling cannot dynamically configure routing policies according to traffic changes. Usually, manual configuration of BGP (Border Gateway Protocol, Border Gateway Protocol) routing policy is required, which requires routers in the entire network to operate one by one, which is a heavy workload and prone to errors. Contents of the invention [0003] In view of the above technical problems, the present invention provides a traffic scheduling method and system, and a software-defined network controller, which realize dynamic scheduling of BGP multi-outlet traffic based on SDN (Software Defined Network, software-defined network) and BGP traffic specifications. [0004] According to one aspect of the present invention, a traffic scheduling method is p...
