Resource optimization method for physical layer resource minimization in Network Function Virtualization (NFV)

Abstract

The invention discloses a resource optimization method for physical layer resource minimization in Network Function Virtualization (NFV). The resource optimization method is as follows: an NFV architecture includes a logical layer, a virtual layer, a physical layer, and an MANO; the logical layer includes logical nodes and controllers; the physical layer includes physical nodes; the logical nodesand the controllers respectively send an information signal to a base station via corresponding physical nodes and an orthogonal channel; the base station calculates, based on the information signal,an effective load bit number, a channel used number, a transmitting power, a receiving signal-to-noise ratio, a throughput capacity and a total transmitted energy of each logical node and each controller; and when a third number, an effective load bit number, a receiving signal-to-noise ratio, a first throughput capacity, a second throughput capacity, a first total transmitted energy and a secondtotal transmitted energy meet corresponding requirements, and the logical nodes and the controllers meet an ultra reliable requirement, the MANO adaptively allocates transmitting powers and channel used numbers based on a hybrid optimization algorithm to minimize a physical layer resource.

Description

technical field [0001] The present disclosure relates to the technical field of network virtualization, and in particular to a resource optimization method for minimizing physical layer resources of network function virtualization. Background technique [0002] As end-user demands for services with more diverse high data rates continue to increase, Telecommunications service providers (TSPs) must accordingly and continuously purchase, store and operate new physical equipment. This not only requires the rapidly changing skills of the technicians who operate and manage the equipment, but also requires dense deployment of network equipment, which results in high operating expenditure (Operation Expenditure, OPEX) and capital expenditure (Capital Expenditure, CAPEX). Network Function Virtualization (Network Function Virtualization, NFV) has been proposed as a solution to these challenges, it uses virtualization technology to provide new ways to design, deploy and manage network ...

AI Technical Summary

Problems solved by technology

In addition, since the optimization problem of minimizing physical layer resources in uplink (UL) transport protocols deployed by NFV is highly non-convex, it is difficult to obtain a global optimal solution, and due to excessive constraints in the optimization problem It will lead to low convergence efficiency, and traditional heuristic algorithms cannot directly solve the resource optimization problem of minimizing physical layer resources
