Embodiment Construction
[0061] The idea of the present invention to solve the problems existing in the background technology is that the present invention proposes a virtualized wireless network function orchestration process (VNFPSO) based on economic benefits by establishing a mathematical optimization model for virtualized wireless network function orchestration. In view of the openness of the virtualized wireless access network architecture, the discreteness of network functions, and the exponential emergence of network loads, the classic particle swarm optimization algorithm has been corrected in terms of inertia weight, particle variation, and learning factors, which has accelerated the overall The solving speed of the approximate optimal solution helps to reduce the service rejection rate of the virtualized wireless access network and improve the utilization rate of network system resources.
[0062] Such as figure 1 As shown, the present invention provides a virtualized wireless network fun...

The invention discloses a virtualized wireless network function editing method based on economic benefits. According to the method, a virtualized wireless network function arrangement mathematical optimization model is established, and a virtualized wireless network function arrangement process (VNFPSO) based on economic benefits is provided. Aiming at the openness of a virtualized wireless accessnetwork architecture, the discreteness of a network function and the exponential appearance of a network load, the classical particle swarm optimization algorithm is corrected in the aspects of inertia weight, particle variation, learning factors and the like, and the solving speed of a global approximate optimal solution is increased. According to the invention, the service rejection rate of thevirtualized wireless access network is reduced, and the utilization rate of network system resources is improved.
Description
technical field [0001] The invention relates to the communication field, in particular to a virtualized wireless network function programming method based on economic benefits. 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 other functional 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 resources. The European...
