Integration Of Three Networks , Definition And Classification

The triple play is conceptually analyzed from different perspectives and levels. It can involve technology convergence, service convergence, industry integration, terminal convergence, and network convergence.

1, basic digital technology. With the rapid development and adoption of digital technology, telephone, data and image signals can all be transmitted and exchanged through a unified code. All services will become a unified “0” or “1” bit stream in the network. All services will become a unified 0/1 bit stream in the digital network, so that voice, data, audio and video content (regardless of their characteristics) can be transmitted, exchanged, routed and processed through different networks. Provided and stored by digital terminals or presented in front of people in a visual and audible manner. Digital technology has been fully applied in telecommunication networks and computer networks and has been rapidly developed in broadcast television networks. The rapid development and full adoption of digital technology has enabled voice, data and image signals to be transmitted and exchanged through a unified digital signal code, laying the foundation for the transmission, exchange, selection and processing of various information.

2, broadband technology. The main body of broadband technology is optical fiber communication technology. One of the goals of network convergence is to provide a unified service over a network. To provide unified services, it is necessary to have a network platform that can support the transmission of multimedia (streaming) services such as audio and video. These services are characterized by large business requirements, large amounts of data, and high quality of service requirements. Therefore, they generally require very large bandwidth during transmission. In addition, from the economic point of view, the cost should not be too high. In this way, the large-capacity and sustainable high-capacity optical fiber communication technology becomes the best choice for transmission media. The development of broadband technologies, especially optical communication technologies, provides the necessary bandwidth, transmission quality, and low cost for the transmission of various service information. As a pillar technology in the field of contemporary communications, optical communication technology is growing at a rate of 100 times per decade. Optical fiber transmission with a huge capacity is the ideal delivery platform for the "Three Networks" and the main physical carrier for the future information superhighway. Whether it is a telecommunications network, a computer network, or a broadcast television network, high-capacity optical fiber communication technologies have been widely used.

3, software technology. Software technology is the development of the neural system and software technology of the information dissemination network, which enables the three major networks and their terminals to eventually support the features, functions, and services required by various users through software changes. Modern communication devices have become highly intelligent and software products. Today's software technology already possesses the means to implement triple-network service and application convergence.

4, IP technology. After the content is digitized, it cannot be directly carried on the medium of the communication network. It also needs to build a bridge between content and transmission media through IP technology. The generation of IP technology (especially IPv6 technology) meets the need to establish a simple and uniform mapping between multiple physical media and diverse application requirements. It can successfully handle multiple business data, multiple hardware and software environments, and multiple The communication protocol is integrated, integrated, unified, and the network resources are comprehensively scheduled and managed so that various IP-based services can be implemented on different networks. The widespread adoption of the IP protocol makes it possible for various IP-based services to interoperate on different networks. It does not matter what the underlying underlying network is.

The development of optical communication technology provides the necessary bandwidth and high transmission quality for the comprehensive transmission of various business information, making it an ideal platform for the triple play business.

The development of software technology makes the three major networks and their terminals change through software, ultimately supporting the features, functions and services required by various users.

The universal adoption of the unified TCP/IP protocol will enable various IP-based services to interoperate on different networks. For the first time, human beings have a unified communication protocol acceptable to all three major networks, laying the most solid foundation for triple-network convergence.
