Network Functions Virtualization (NFV) is an initiative to increase the use of virtualization and commercial servers in the Telco Service Providers networks.
The NFV leverages IT technologies, including virtualization, standard servers and open software to radically change the way networks are created and managed.
NFV together with Software Defined Networking (SDN) is rapidly determining radical changes in the telecommunication scenario. Network equipment previously implemented with proprietary closed boxes, contained a bundle of proprietary SW and customized HW provided by a single Telecom Equipment Manufacturer. Adopting NFV, network equipment become Virtualized Network Functions that can be automatically managed and assembled in order to provide Network Services.
The NFV solutions proposed by Italtel leverage on two focal achievements:
• the main products in the Italtel product portfolio are compliant to the ETSI NFV specifications and reference architecture and they are available as VNF (Virtualized Network Functions) according to the ETSI definition
• a NFV Management framework is available for complementing the Italtel VNFs in the implementation of NFV solutions.
The Italtel Neutral VNFM implements the Virtual Network Functions Manager (VNFM) function for the management of Italtel and/or other vendors’ VNFs.
