The softwarization of mobile networks enables an efficient use of resources, by dynamically
scaling and re-assigning them following variations in demand. Given that the activation of …

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 …

Auto-scaling techniques aim to keep the right number of active servers for the current load: if
this number is too small we risk service disruption, but if it is too large we waste resources …

Abstract The Network Function Virtualization (NFV) has been conceived as an enabler of
novel network infrastructures and services that can be deployed by combining virtualized …

Due to the intrinsically inefficient service provisioning in traditional networks, Network
Function Virtualization (NFV) keeps gaining attention from both industry and academia. By …

A highly reliable set up of Management and Orchestration (MANO) functionality is crucial for
telecom operators in order to support demanding NFV-powered telecom services such as …

Network Function Virtualization (NFV) represents a key shift in nowadays network service
provisioning by entailing higher flexibility, elasticity, and programmability of network …
