Design and Placements of Virtualized Network Functions for Dynamically Changing Service Requests Based on a Core/Periphery Structure

IEEE Access, 2020
Network Function Virtualization (NFV) is a system that provides application services by connecting virtual network functions (VNFs), and is expected to accommodate new service requests through the development of new VNF and connection with existing ones.

Multi-objective VNF Placement Optimization with NSGA-III

, 2023
With the rising acceptance of virtual network functions (VNFs) as a replacement for traditional network functions, the optimal placement of VNFs has become a crucial task for ensuring constant performance within constrained resources. This research investigates the challenge of mapping and scheduling VNFs as a multi-objective optimization problem.
