Service function chain SFC resource allocation method based on SDN and NFV, and electronic device

Abstract

The invention provides an SDN and NFV-based service function chain SFC resource allocation method and electronic equipment, and the method comprises the steps: constructing a network mapping model based on a software defined network SDN and a network function virtualization technology NFV; determining total user utility according to the network mapping model; predicting network state information of the network mapping model at the next moment; determining a resource allocation algorithm according to the principle of maximizing the utility of the total user and the network state information at the next moment, and operating the resource allocation algorithm on an SDN controller in the network mapping model; and determining a service function chain SFC to be allocated from the service function chains SFC by using the SDN controller according to a resource allocation algorithm, and performing resource allocation on the service function chain SFC to be allocated. According to the resource allocation method provided by the invention, in the long-term operation process of the network, the maximization of the utility of the user can be achieved under the condition of keeping the resource consumption of the physical network unchanged.

Description

technical field [0001] The present application relates to the field of communication technology, and in particular to a SDN and NFV-based service function chain SFC resource allocation method and electronic equipment. Background technique [0002] At present, software-defined network SDN (Software Defined Network) and network function virtualization technology NFV (Network Functions Virtualization) have been widely used in the research of network resource orchestration. With the help of SDN technology, network equipment has changed from a closed mode to an open general equipment mode. , so that the control plane and data plane are separated, which allows the network to be programmed through an open interface; with the help of NFV technology, the network element function can be deployed on the general server node of the infrastructure in the form of software, so that the network element function and dedicated hardware Device separation. The network resource orchestration sys...
