All About Next Generation Network

As the term suggests, Next Generation Network (NGN) is the future of data communication. It’s touted as the replacement for Public Switched Telephone Network (PSTN) and Integrated Services Digital Network (ISDN). Let’s find out more about NGN and its capabilities.

What is Next Generation Network

Next Generation Network is a packet-based network for telephonic and data communication. These networks use broadband capabilities and Quality of Services (QoS) transport technologies to deliver data across networks. In Next Generation Networks, service-related functions are not dependent on transport-related functions.

What are the fundamental aspects of Next Generation Network?

At its core, Next Generation Network is a unified communication network for telephony, cellular, and internet networks. Its primary purpose is to serve as a replacement for different telecommunication and data networks. NGNs are mostly built on Internet Protocol (IP). Next Generation Networks are also called all-IP networks. NGN is an approach toward mobility, and its aim is to provide consistent service to users.

Next Generation Networks separate the service from the network. As a result, it allows for open interfaces (I/F). NGN also supports real-time streaming, non-real-time streaming, and multimedia transfer. It brings unrestricted access to users from various service providers.

NGN supports the following services:

  • Data communication
  • Public interest services
  • Multimedia
  • Integrated Services Digital Network (ISDN) simulation services
  • Public Switched Telephone Network (PSTN) simulation services
  • Integrated Services Digital Network (ISDN) emulation services
  • Public Switched Telephone Network (PSTN) emulation services

NGN has three layers: service, control, and access. The access network supports media gateways, while the control layer acts as the call server. On the other hand, the service layer is an intelligent network that covers new network scenarios.

The drive towards a unified network for all forms of communication will eventually benefit organizations of all sizes and scales.

Features of Next Generation Network

In order to facilitate technological advancements and the creation of high-speed, varied services, NGN features a layered structural model. It complies with both national and international standards. Following these standards enables different participants, including application service providers and video broadcasters, to provide a variety of application services. Additionally, NGN offers an open network and guarantees communication with other IP networks, such as Internet service providers (ISPs).

The features of Next Generation Network are as follows:

Security: NGN has the capability of tracking data and signals traffic, as well as verifying phone numbers, IP addresses, and other sources of originator identification. Additionally, it has the ability to stop suspicious traffic at network entry and exit nodes.

Reliability: Every single communication device in the NGN is reliable. Network-oriented remedies are used to maintain high dependability while securing crucial communications. These involve deploying redundant communication circuits, equipment configurations, and traffic-control strategies for addressing traffic congestion.

High-quality connectivity: NGN offers high-quality broadband connectivity by managing the QoS end-to-end. For instance, a high-priority QoS class would be given the bandwidth required to allow the user to appreciate HDTV-quality audio or video without thinking about QoS degradation.


Next Generation Network is the future of communication. We hope this guide intrigues you to learn more about these networks.

My life has been surrounded with computers since I was a child, from my first job as a Computer Assembly Assistant to the current ownership of Priority Networks, a dental focused networking company. Starting with an Apple computer connecting to other networks when I was only 13 years old, I quickly knew this passion would lead to bigger ventures. As the internet started to evolve, I immediately worked for an Internet Service Provider (ISP). This gave me insight to the power of worldwide internet communications and the capabilities of sharing data across multiple networks simultaneously. The dedication towards this field has given me the advantage of understanding new technologies and grasping complicated issues quickly from software, hardware, networking, security, management and much more. As a Computer Network Manager for Tesma International, a division of Magna International, I gained the experience of becoming a qualified NAI Network Sniffer, EDI Communications Specialist, Head Securities Manager, MRP Manufacturing Integration Manager, and received several enhanced managerial and technological training courses. Moving forward to today, I apply all my knowledge, training and years of solid network experience to deliver the very best support to all my customers at Priority Networks.
