Software-defined network dynamic bandwidth allocation method, device, device and storage medium

Abstract

The invention provides a software defined networking dynamic bandwidth allocation method and device, an electronic device and a storage medium. The software defined networking dynamic bandwidth allocation method comprises steps of receiving a virtual network request, wherein the virtual network request consists of multiple virtual link requests, searching target resource distribution information matched with the virtual link request from a pre-stored recourse distribution information database by targeting each virtual link request in the virtual network request, wherein the resource distribution information database stores corresponding relations between multiple historical virtual link requests and the resource distribution information and the resource distribution information comprises a distributed path and a distributed bandwidth, if the target resource distribution information is searched, taking the searched resource distribution information as resource distribution information corresponding to the virtual link request. The software defined networking dynamic bandwidth allocation method and device, the electronic device and the storage medium can reduce complexity during the resource distribution process.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a software-defined network dynamic bandwidth allocation method, device, device and storage medium. Background technique [0002] NV (Network Virtualization, Network Virtualization) allows multiple virtual networks to coexist on the same physical network, and provides services to different users through multiple virtual networks sharing the same physical resources. But the configuration and operation of traditional network virtualization are complicated. In order to simplify configuration and operation of multiple virtual networks and further facilitate management, SDN (Software Defined Networking, software-defined network) is applied to network virtualization. SDN separates the control plane from the data plane, and centrally manages all network resources through the controller, which makes network management flexible and efficient. [0003] By combining SD...

Problems solved by technology

It can be seen that in the existing allocation method, every time a virtual network request is received, it is necessary to traverse the topology structure of all physical nodes in the network, and then determine resource allocation information such as the shortest path, which makes the resource allocation process too complicated
