Abstract

The invention discloses a service traffic scheduling method and system, a traffic controller and a network edge device, and relates to the field of communication. According to the embodiment of the method and system, the traffic controller and the network edge device, through adoption of a centralized control mechanism, the network configuration and management work is simplified; the traffic controller generates flow tables according to service strategies and sends the flow tables to each network edge device in real time; network virtual path action fields are extended in the flow tables; the network edge devices identify service traffic according to the flow tables and forward the service traffic according to corresponding network virtual paths; therefore, the service traffic is scheduled in real time; and the adjustment response of service shunting is relatively rapid.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a method and system for scheduling service flow based on OpenFlow technology, a flow controller, and network edge equipment. Background technique [0002] Traffic engineering based on MPLS (Multi-ProtocolLabelSwitching, Multi-Protocol Label Switching) is often used in carrier networks. It mainly pre-binds service traffic paths in a static manner. Specific traffic flows through the link, enabling traffic scheduling. [0003] In this static implementation mode, the adjustment response of service distribution is slow, and each router needs to be configured, and the network configuration content is relatively large. Contents of the invention [0004] A technical problem to be solved by the embodiments of the present invention is that the adjustment response of service distribution is relatively slow, and the network configuration content is relatively large. [0005] In the ...
