A Multi-phase Heuristic Algorithm for VNF Mapping and Scheduling

Abstract Network function virtualization (NFV) is a transformative networking paradigm that leverages virtualization and cloud computing technologies to transform physical network functions, traditionally deployed on proprietary hardware middleboxes, into virtualized network functions (VNFs). This task is achieved by implementing these network functions in software that runs as virtual machines (VM) on commercial hardware within high-performance data centers, known as network function virtualiza
