Abstract The emergence of Network Function Virtualization enables the deployment of
network services in the form of service function chains. In this context, one of the key …

With the growing adoption of Software Defined Networking (SDN) and Network Function
Virtualization (NFV), large-scale NFV infrastructure deployments are gaining momentum …

Network function virtualization (NFV), a novel network architecture, promises to offer a lot of
convenience in network design, deployment, and management. This paradigm, although …

With the emergence of software defined networking and network function virtualization
technologies, network services are expected to be offered as service function chains made …

Network function virtualization can significantly improve the flexibility and effectiveness of
network appliances via a mapping process called service function chaining. However, the …

Network Function Virtualization (NFV) is an emerging technology decouples network
functions from hardware. Network service in NFV is deployed as a service chain, also known …

Network Function Virtualization (NFV) decouples network functions from dedicated
hardware platforms, and reduces the cost of proprietary physical equipment. In NFV …

Network Functions Virtualization (NFV) is an emerging initiative where standard IT
virtualization evolves to consolidate network functions onto high volume servers, switches …
