Abstract

The invention provides a software-defined network controller supporting dynamic and elastic scheduling for resource, which comprises a resource virtual layer and a core control layer, wherein the resource virtual layer is used for acquiring the network resource from a plurality of bottom layer equipment and virtualizing the network resource so as to obtain the virtualized network resource; the core control layer is used for controlling an upper layer application to obtain the virtualized the network resource from the resource virtual layer and is respectively connected with the resource virtual layer and the upper layer application. According to the software defined network controller provided by the embodiment of the invention, the core control layer is adopted for controlling data interaction between the upper layer application and the resource virtual layer, so as to improve the utilization ratio of the network resource, and realize the dynamic and flexible scheduling for the network resource.

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...
