Abstract

The present invention proposes a software-defined network controller that supports dynamic elastic resource scheduling, including: a resource virtualization layer, used to obtain network resources from multiple underlying devices, and virtualize the network resources to obtain virtualized network resources; The core control layer is used to control the upper-layer applications to obtain virtualized network resources from the resource virtualization layer, and the core control layer is respectively connected with the resource virtualization layer and the upper-layer applications. According to the software-defined network controller of the embodiment of the present invention, the core control layer monitors the data interaction between the upper layer application and the resource virtual layer, thereby improving the utilization rate of network resources and realizing the dynamic and flexible scheduling of network resources by the application layer.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a software-defined network controller supporting dynamic elastic resource scheduling. Background technique [0002] At present, the scale of the Internet and the total amount of services are showing explosive growth. In the telecommunication network, the data service has surpassed the traditional voice service, and has gradually become the mainstream service carried by the telecommunication network. Because the data service has the characteristics of flexible bandwidth and strong burst, it is difficult for the traditional telecommunication network designed to carry the voice service to adapt to the above characteristics. In order to enable the telecommunication network to efficiently carry data services, it is necessary to upgrade and update the telecommunication network according to the characteristics of the data services. [0003] In order to adapt to the flexib...
