The dependence of traditional network functions (NFs) on special hardware results in high
capital expenditures (CAPEX) and operating expenditures (OPEX). Network Function …

Abstract Network Function Virtualization (NFV) is a novel concept that is reshaping the
middlebox arena, shifting network functions (eg firewall, gateways, proxies) from specialized …

We focus on the placement of Virtualized Network Functions (VNFs) chains in the Network
Function Virtualization (NFV) context where NFV Infrastructures (NFVIs) are used to host the …

Network function virtualization (NFV) is a new network architecture concept that simplifies
the deployment of network services and improves service management. However, it is …

The Network Functions Virtualization (NFV) paradigm offers network operators benefits in
