What is NGN network concept?
A Next Generation Network (NGN) is a packet-based network able to provide services including Telecommunication Services and able to make use of multiple broadband, QoS-enabled transport technologies and in which service-related functions are independent from underlying transport-related technologies.
What are the layers of NGN and its functionalities?
The five function layers are: (1) Application Layer that supports SIP protocol; (2) Network Control Layer that aims at overcoming the bottleneck problems at edge nodes or servers for end-to-end admission control; (3) Adaptation Layer that supports different network configurations and network mobility; (4) Network …
What is NGN and its architecture?
NGN concept. •A multi-service network able to support voice, data and video. •A network with a control plane (signaling, control) separated from. the transport/switching plane.
Where is NGN communication possible?
In an NGN, the QoS class required by a service (e.g., IP telephony, video delivery, or data communications) can be negotiated between the network and terminal/server. This makes it possible to provide services in accordance with stipulated QoS values for each QoS class.
What is NGN as per ITU T?
At ITU-T, international standardization of the NGN (Next Generation Network) is underway by involving various standards organiza- tions.
What is the full form of NGN?
The next-generation network (NGN) is a body of key architectural changes in telecommunication core and access networks.
What is the NGN and why is it important?
The term “next-generation network” or NGN refers to important developments in telecommunication core and access networks to be deployed over the next decade. NGN enables unfettered access for users to networks and to competing service providers and services of their choice.
What is NGN as per ITU-T?
What is the currency of Nigeria?

Which is the core of the NGN network?
1) Transport Layer: Transport Layer of NGN is based on IP and can utilize the advantage of MPLS. Transport Layer forms the core of the Network. It basically consists of an assembly of Routers with optical network, which are responsible for carrying traffic originated by access layer.
What is the next gen network?
a next generation network is a packet-based network that can be used for both telephony and data and that supports mobilility. Initially, the term Next Generation Network was used to refer to the transformation of the core network to IP.
How is the NGN different from the PSTN?
NGN is the culmination of 100 years of telecommunication evolution, combining the scalability and reliability of the public telephone network with the reach and flexibility of the internet. The NGN seamlessly blends the Public Switched Telephone network (PSTN) and the Public Switched Data Network (PSDN), creating a single multiservice network. II.
How is NGN making service separation from network?
Hence NGN is making service separation from Network. Any service can be introduced with the help of server at any time without any modifications in the control, transport or access layers. B. Typical Elements of NGN The NGN consists of some typical elements which contribute as the backbone of this giant network.
