A virtualization resource orchestration method for Internet of Things access based on cro correction

Abstract

The invention discloses an Internet of Things access virtualization resource arrangement method based on CRO correction. The method comprises the following steps: S1, establishing a Web service identification model, when a new Web service arrives, identifying according to the characteristics of the new Web service, selecting components of a virtual network function according to the total resourceamount of a resource pool, and establishing mathematical models for Web application, physical network resources and a virtual network resource arrangement process respectively; S2, converting the mathematical model established in the step S1 into a molecular reaction model; S3, optimizing neighbors in the collision reaction in the step S2 by adopting optimal value Gaussian, and optimizing kineticenergy coefficients of the collision reaction, the decomposition reaction, the exchange reaction and the combined reaction in the step S2 by adopting a dynamic loss function; and S4, performing Internet of Things access virtualization resource arrangement by adopting the model optimized in the step S3. The method has the beneficial effects that the rejection rate of the Internet of Things access service is reduced, and the utilization rate of network system resources is improved.

Description

technical field [0001] The invention belongs to the field of mobile communication, in particular to a resource arrangement method for a virtualized network slice of a wireless mobile communication network. Background technique [0002] With the progress of network function virtualization (NFV) and software-defined network (SDN), virtualized network function orchestration (NFVO) is considered to be the soul of future networks, and will become the key for operators to flexibly manage networks and maximize the advantages of new technologies . NFVO helps standardize the functionality of virtual networks to improve the interoperability of software-defined network elements. It is capable of performing resource orchestration, network service orchestration, and function orchestration. It is able to coordinate, authorize, issue and use resources independently of any specific virtual infrastructure manager, and also provides management of VNF instances sharing NFV infrastructure res...
