Abstract

Software-Defined Networking (SDN) and Network Functions Virtualization (NFV) have recently caught attentions from industries as technologies for reducing capital expense (CAPEX) and operational expense (OPEX), where software-defined programmable network equipment dispenses with high maintenance cost of hardware appliances and enables rapid revisions of functionalities and the automation of operation and management (OAM) of network. While SDN primarily focuses on the programmability on the control of networking, NFV aims at implementing data processing functions in software on top of virtual machines (VMs) especially that exist today as hardware network appliances. Data packets can be programmatically redirected by SDN and can be programmatically processed by NFV.
