Infrastructure EvolutionIt is a Multilayer TransformationIt is a Multilayer Transformation
• NGN is a term used for networks that used technologies (in most of the cases IP) allowing to achieve convergence in order to carry voice, video and data over the same infrastructure rather than separate networks (core centric definition)
• This transformation will reach out/impact many layers of the infrastructure and not just the core
• This transformation will follow an evolutionary approach toward support of “mass customised” services and beyond
• The starting driver may differ from one operator to another
Existing Network End of Life

Infrastructure Evolution Multilayer - Reach and ScopeMultilayer - Reach and Scope
• Next Generation Core is delivered by the means of changing the equipment for transmission and switching
Converged Network
• When it is touching the access it is referenced as Next Generation Access
Higher bandwidth, Greater symmetry, Lower contention, Supporting higher peaks
• Next Generation Service Platform is the platform controlling the services
The provision and programmability of services
• Together NGC, NGA and NGSP will create the NGN Framework of the future.
• The Implementation sequence varies in terms of rational, span, benefits and time period

Use of standards for NGN networking equipment
Efficiency gain with IP
• Network maintenance, outsourcing costs
Fewer network elements
Fewer Interfaces
Large savings in network maintenance.
