Embodiment

[0044] The following takes the router traffic scheduling of a domestic operator's Internet Data Center (IDC, Internet Data Center) as an example for specific instructions, such as figure 2 , image 3 As shown, the city’s IDC contains multiple routers, which belong to different manufacturers. Each router includes more than ten links, which are connected to Internet backbone network access routers, metro core routers, provincial IDC convergence routers and other routers. Establish BGP interconnection. The interface types, link bandwidth, bandwidth utilization, and expansion conditions of the above links are quite different.

[0045] By deploying SDN technology in provincial IDC / prefecture and municipal IDC equipment, based on the destination IP, it can realize the intelligent unblocking and scheduling of intra-city, intra-provincial, and inter-provincial traffic, eliminate part of the uneven busy and idle conditions, and improve the bandwidth utilization rate of the operator's back...

Abstract

The invention discloses a comprehensive unified flow scheduling system and scheduling method based on a SDN (Software Defined Network). In the system, a routing information collection device first determining the network topology of a network service provider in the system; second, a flow collection device regularly collecting SDN forwarding device flow states of different manufacturers, and analyzing the flow load state of each port and link in each direction; third, according the forwarding strategy designated by a user, a strategy generation device determining a BGP (Border Gateway Protocol) scheduling strategy according to practical information; and finally realizing strategy issuing and performing network device management on the strategy. The method allows a service provider network to span the wide gap among the SDN devices of different manufacturers, realizes network flow unified scheduling and controlling, and meanwhile emancipates operation personnel from a large scale task amount of different operations on the devices of different manufacturers.

Description

Technical field [0001] The present invention relates to the technical field of network communication, in particular to an SDN (Software Defined Network) controller and SDN forwarding equipment, and more specifically to an SDN-based integrated unified traffic scheduling system and a scheduling method thereof. Background technique [0002] Through the deployment of Software Defined Network (SDN, SoftwareDefinedNetwork), operators can achieve rapid and flexible service deployment, accelerate service innovation, optimize traffic models, control key service traffic, make full use of operators' pipeline resources, and greatly improve their competitiveness. [0003] At present, in terms of traffic scheduling, operators usually adopt Border Gateway Protocol (BGP, BorderGateway Protocol) strategy to achieve. A common practice is to log in to the router to manually adjust the BGP routing strategy and change the flow of specific services. This is time-consuming, laborious, poor real-time, an...
