Network Function Virtualization (NFV) is an emergent paradigm that is currently transforming
the way network services are provisioned and managed. The main idea of NFV is to …

Using Network Functions Virtualization (NFV), network functions are virtualized and chained
together to provide a network service. Often, a service chain can be allocated in multiple …

Network function virtualization requires scaling and placement, deciding the number and the
location of function instances. Current approaches are limited in flexibility and practical …

Network function virtualization (NFV) has been emerging as a new paradigm to enable
elastic and inexpensive network services in modern computer networks, through deploying …

Network Function Virtualization (NFV) is a novel paradigm that enables flexible and scalable
implementation of network services on cloud infrastructure. A key factor in the success of …

Over the past decades, the scale of communications networks has been growing rapidly with
the emergence of more and more network-based services. However, network operators all …

Network function virtualization (NFV) implements network middleboxes in software, enabling
them to be more flexible and dynamic. NFV resource allocation methods can exploit the …

By allowing network functions to be virtualized and run on commodity hardware, NFV
enables new properties (eg, elastic scaling), and new service models for Service Providers …

Diverse proprietary network appliances increase both the capital and operational expense
of service providers, meanwhile causing problems of network ossification. Network function …

Abstract The idea of Network Function Virtualization (NFV) is to decouple of network
functions from dedicated hardwares to obtain higher flexibility in terms of network …
