Abstract

The invention relates to a software-defined network load balancing device and method, belonging to the technical field of mobile communication. In this method, the core network switch is virtualized into a virtual switch according to the service support capability, and then a network slice is constructed based on the virtual switch; the load balancing device of the SDN control plane collects user service characteristic information and network slice status information, and evaluates the data flow routing load State and virtual switch load state in the slice, determine the network slice data flow routing switching strategy, in order to achieve load balancing between network slices and within the slice. The present invention can effectively realize the load balance among network slices and within the slices, thereby effectively improving the utilization rate of network equipment and user QoS.

Description

Technical field [0001] The invention belongs to the technical field of mobile communication, and relates to a software-defined network load balancing device and method. Background technique [0002] Software Defined Networking (SDN) is a new network architecture based on OpenFlow proposed by Stanford University. The typical architecture of SDN is divided into three layers. The top layer is the application layer, which includes various services and applications; the middle layer is the control layer, which is mainly responsible for the arrangement of data forwarding equipment resources, and maintenance of network topology and status information; the bottom layer As the data layer, it is mainly responsible for data processing, forwarding and state collection based on the flow table. The main features of SDN are the separation of the control plane and the data plane, centralized network control, open network interfaces between the control layer and data layer devices, and the netwo...
