Abstract

The invention discloses a service flow scheduling method and system, a flow controller and network edge equipment, and relates to the communication field. The embodiment of the present invention simplifies the network configuration management work through the centralized control mechanism, and the traffic controller generates a flow table according to the service policy, and sends it to each network edge device in real time. The network virtual path action field is extended in the flow table, and the network edge The device identifies service traffic according to the flow table and forwards it according to the corresponding network virtual path, so as to realize real-time scheduling of service traffic, and the adjustment response of service offloading is relatively fast.

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-Protocol Label Switching, Multi-Protocol Label Switching) is often used in carrier networks. It mainly pre-binds service traffic paths in a static way, and requires pre-configured end-to-end soft channels and service traffic distribution portals. , designate specific traffic to flow through the link, so as to realize 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 s...
