Now that you have completed the Fiber Theory and Fiber Handling Modules, in the next section we will begin to discuss some of the applications that may influence service providers in moving to an all fiber network. Welcom to the beginning of the ADC On-Line PON Design Training Series. Next Generation Networking ( NGN ) is a broad term to describe some key architectural evolutions in the telecommunications core and access networks that will be deployed over the next 5-10 years. The general idea behind NGN is that one network transports all information and services such as voice, data, video and all sorts of applications by encapsulating these into packets, using techniques that are similar to the techniques used to access the Internet. NGNs are commonly built around the Internet Protocol, and therefore the term "all-IP" is also sometimes used to describe the transformation towards NGN. For the “Next Generation Architecutres,” the International Telecommunications Union (ITU) definition, a Next Generation Network (NGN) is a packet based network able to provide services including Telecommunication Services or telephony, and able to make use of multiple broadband, Quality-of-Service (QoS) enabled transport technologies and in which service-related functions are independent from underlying transport-related technologies. The NGA will offer unrestricted access by users to different service providers. It supports generalized mobility which will allow consistent and ubiquitous provision of services to users. From a practical perspective, NGN involves three main architectural changes that need to be looked at separately: 1.) In the core network, NGN implies a consolidation of several (dedicated or overlay) transport networks each historically built for a different service into one core transport network (often based on IP and Ethernet). 2.) It implies amongst others that the migration of voice from a switched architecture “Public Switched Telephone Network (PSTN) to Voice over IP (VOIP). 3.) It is also the migration of legacy services to either commercial migration of the customer to a new service like IP VPN, or technical emigration by emulation of the "legacy service" on the NGN.
