Abstract

The present invention relates to a method and a system for flow scheduling based on an MPLS (Multi-Protocol Label Switching) in SDN (Software Defined Network) technology. The method is based on an SDNnetworking technology, an SDN controller senses total network topology to obtain real-time network topology of the total network, flow load statistics for each link is regularly performed, flow scheduling paths are subjected to optimization calculation based on a multi-constraint CSPF algorithm, and an OpenFlow protocol is employed to issue forwarding flow table of label matching and label exchange based on the MPLS technology to an SDN switch in an LSP path to perform scheduling optimization of the flow.

Description

technical field [0001] The invention belongs to the field of network communication, and in particular relates to a flow scheduling method and system based on MPLS in SDN technology. Background technique [0002] With the rapid development of the Internet, the network traffic driven by various user needs shows explosive growth, the development of various OTT services based on the Internet and cloud computing, and cloud service providers that provide computing, storage, network and other infrastructure rental services With the rise of the Internet of Things, the traffic flow and change trend of the carrier's backbone network are showing characteristics of unpredictability and increased volatility. Traditional manual traffic scheduling is difficult to adapt to the new traffic characteristics. The existing traditional traffic scheduling methods are increasingly difficult to meet the needs of network development. [0003] Software-defined network (Softwae Defined Network, SDN) i...
