Abstract The Network Function Virtualization (NFV) virtualizes the network appliances—such
as routers and firewalls—with software running on commercial off-the-shelf servers. In NFV …

Multi-domain federations support shared network services. Many orchestrators manage the
service's lifecycle. For the shared VNF Forwarding Graph (VNF-FG) reconfiguration …

Network Function Virtualization (NFV) replaces proprietary network appliances by
softwarizing them in commodity servers and they are called as Virtual Network Functions …

Network Function Virtualization (NFV) enables running Virtualized Network Functions (VNF)
on top of any generic, commercial off-the-shelf hardware. VNFs rely on the VNF-Forwarding …

Network Function Virtualization (NFV) promises an efficient way of managing and
orchestrating Virtual Network Functions (VNFs), where VNFs can be dynamically …

In this paper we focus on the problem of multidomain orchestration for Network Function
Virtualization (NFV), over multi-technology environments. In order to facilitate service …

Motivated by the vision of Network Functions Virtualisation (NFV) spanning different
administrative domains, this position paper makes the case for multi-domain, distributed …

One of the main challenges to use network functions virtualization (NFV) is to properly
manage the life cycle of the virtualized network functions (VNFs). Current solutions based on …

Network function virtualization is an emerging concept that is attracting increasing attention
in the industry because it offers high levels of agility and flexibility to the network allowing …

Network Function Virtualization (NFV), considered a key enabler of network" softwarization",
promises to reduce capital and operational expenditures for network operators by moving …
