Abstract

The present invention relates to a flow scheduling method and system based on MPLS in SDN technology. The method is based on SDN networking technology. The SDN controller perceives the topology of the entire network, obtains the real-time network topology of the entire network, and periodically performs traffic load statistics on each link. Based on the multi-constraint CSPF algorithm, the traffic scheduling path is optimized and calculated, and then the SDN switch in the LSP path is delivered to the SDN switch in the LSP path through the OpenFlow protocol. .

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...
