NGN and triple network integration

It's a pleasure to discuss such topics with my peers.

1. Noun analysis: NGN: refers to the next generation telecommunications network. It is a new IP-based communication network that can carry a wide variety of services such as voice, data, and multimedia.

The three networks in "triple network integration" refer to: the traditional telecommunications network represented by the telephone network (including mobile communication network); the data communication network represented by the Internet; and the radio and television network represented by the cable TV network.

.

"Three networks" represent the infrastructure of three different industries in the modern information industry, namely the telecommunications industry, the computer industry and the cable television industry.

It can be seen that NGN is one of the components of the "Three Networks", or a subset of the three integrated networks.

Do you agree with this statement?

2. The relationship between the evolution of NGN and the integration of three networks. NGN is a distributed, carrier-grade, end-to-end network built on a single packet switching network using soft switching technology, various application servers and media gateway technologies.

End-to-end unified network.

NGN brings together fixed, mobile, broadband and other networks, and is committed to perfect interoperability with PSTN and mobile networks.

At the same time, NGN provides an open system architecture to facilitate the rapid development and deployment of new services.

The so-called "triple network integration" also means that the future telecommunications network, TV network and Internet can carry a variety of information services and create more integrated services, rather than three networks merging into one network. Therefore, the three networks

Convergence is not the unification of three networks.

In a narrow sense, triple play is the integration and convergence of telecommunications networks, cable TV networks and computer networks. In a broad sense, it is the integration of telecommunications, media and information technology.

It is an inevitable choice for the three networks in the process of evolving to their respective next-generation networks.

From the perspective of service providers, it refers to the tendency of different network platforms to carry substantially similar services; from the perspective of end users, it refers to the convergence of consumer user devices (such as phones, televisions and personal computers).

Based on the above concepts of NGN and triple network integration, it is not difficult to see that whether it is the evolution from the existing telecommunications network to NGN or the integration of the three networks, the two ideas are completely consistent, and they are not a technological revolution.

, but a revolution in the network system.

The network system is based on IP network as the carrying platform and combines multiple access methods. It will support multiple services such as voice, data and multimedia, and has an open business API interface and flexible configuration and customization capabilities for services.

In other words, at the technical level, the technical basis of the two (digital technology, optical communication technology, software technology, unified communication protocol) is completely consistent, and at the business level, the capabilities provided are also the same.

The evolution roadmaps are even the same, with network integration first and then business integration.

The difference between the two may be because NGN originated from connection-oriented circuit switching and places more emphasis on quality of service (QOS) and network manageability.

However, as the integration of the three networks goes deeper, in order to optimize the application experience of customers and improve the operational efficiency of operators, these two indicators will definitely be paid attention to by the other two networks.

The pace of traditional telecommunications networks moving towards NGN directly determines the speed of three-network integration.
