As the United States relaxes the mixed operations of telecommunications and television companies, cable TV companies have entered the telephone and network market through the advantages of their laying cables and fiber optic transmission signal networks; telephone companies have begun to expand network and television services through facility upgrades and mergers. The services provided by companies originally divided into different fields are becoming smaller and smaller, and the integrated model of "voice + video + data" is becoming more and more common, and is developing towards "voice + video + data + wireless".

Due to the United States' leading effect in the information industry, Britain, Japan and other countries have also begun to follow the example. At this time, domestic peers who have been tracking the latest trends in the foreign information industry have proposed their own "three-network integration" plan. They proposed that network integration can be divided into three stages, first of all, unified industrial standards; secondly, infrastructure integration; then extension and expansion stage, that is, the integration of various communication services. With the advancement of technology, now the era of audio, video, email and instant messaging are integrated into a function on computers or mobile phones has arrived. It is the general trend that the three networks are unified into one backbone network.

On the surface, China has a great latecomer advantage in this regard, because the United States, Britain and other countries first need to renovate the old copper wire telephone network and also unify the adoption of a large number of equipment of different standards in different eras. Before China reform, there was almost no concept of private telephones, and landlines entered thousands of households for only about ten years. There was no drag on a large number of outdated technologies and equipment. In many aspects, it can be achieved in one step, which can speed up the integration of the three networks.

But the reality is that various industries and departments are divided seriously and they are arguing with each other. The integration of the three networks has been delayed in China. It was not until Yang Xing’s rebirth that the State Council was forced to start due to the strong intervention of the State Council. Many departments often argued for the sake of dominance, which led to the slow progress of this plan. Yang Xing suggested that because this involves the growth of the domestic information industry and information security in the next few decades, the government must take the lead and play a management and guiding role in the process of network integration.

According to the successful experience of the United States, Britain and other countries, the integration of management agencies is an inevitable requirement for the development of network integration to a certain extent. The UK established a unified communications industry management agency, integrating the functions of multiple management agencies such as telecommunications, television, radio, and wireless communications, which greatly promoted the industrial development of network integration. my country should also establish a cross-departmental coordination agency as soon as possible to clarify action plans and effective policies, mechanisms, guide and encourage industrial chain coordination with the national will. Give operators a clear signal to avoid companies misjudging government intentions.

At the same time, we must unify the understanding of the integration of three networks, draw a detailed road development map, and formulate a three-network integration timetable based on the steps of technological integration, business integration, industry integration, terminal integration and network integration. The integration of three networks first relies on basic digital technology. With the rapid development and comprehensive adoption of digital technology, various signals of voice, data, audio and video can be transmitted and exchanged through unified encoding, and converted into a unified 01-bit stream in the network environment. This makes it possible to transmit, exchange and process these contents through different networks. They are stored through digital terminals or presented to people in visual and auditory ways.

At present, digital technology has been fully applied in telecommunications networks and computer networks, and has developed rapidly in broadcasting and television networks. After the content is digitized, it cannot be directly carried on the communication network medium. It is necessary to build a bridge between the content and the transmission medium through IP technology. The emergence of IP technology meets the need to establish a simple and unified mapping between multiple physical media and diverse application needs, and can smoothly integrate, integrate and unify a variety of service data, multiple software and hardware environments, and multiple communication protocols. The network resources are comprehensively scheduled and managed, so that various IP-based services can be interoperated on different networks.

The universal adoption of the unified tcpip protocol will enable various IP-based services to be interconnected on different networks. For the first time, human beings have a unified communication protocol that is acceptable to all three major networks, which has technically laid the most solid foundation for the integration of three networks. This is also the reason why Yang Xing proposed to merge the IPv6 issues discussed in the conference into the integration of three networks.

In this field, Director Wu, Director of the CNGI Expert Committee, vividly explained the role of IPV6 in promoting network integration. He believed that when designing the Internet in the past, the Internet speed was not considered in the future and the number of network users increased rapidly, resulting in the fact that it can only rely on continuous repairs to improve the Internet construction.

"It's like a traffic jam on a section of highway. If the traffic police do not do the timely and inadequate guidance, traffic jams will become more and more serious. If the design of the Internet is forward-looking and all unknown changes are designed within the scope of consideration, then it will have considerable flexibility. The flexibility directly determines the performance indicators that ordinary users can see, such as whether watching videos will get stuck and whether making Internet calls will be disconnected. It is expected that we will launch a new generation of routers for netizens to use in the future. If it is matched with enough bandwidth, it will not be a dream to download a high-definition movie in the future in a few seconds."

Based on this, industry experts, operators, equipment vendors and relevant industry insiders soon reached a consensus, and strongly demanded that the competent authorities come forward to coordinate the deployment and research and development of key links of the next generation Internet, realize the simultaneous transformation of the network and website, and promote the simultaneous development of fixed and mobile networks, technologies, equipment, and applications. At the same time, the national science and technology plan projects should also increase support for the research and development and industrialization of IPV6 and the next generation Internet, and introduce policies to encourage government departments and large enterprises to work together and actively participate.

To lay a solid foundation for network integration, we also need to work hard on both software and hardware. Software technology is the nervous system of the information dissemination network, so that the three major networks and their terminals can ultimately support various users' characteristics, functions and services through software changes. This is a major feature of the integration of three networks abroad. Modern communication equipment has become a highly intelligent and software-based product. Today's software technology has met the requirements of the integration of three networks business and application. Yang Xing has also been working hard on this matter, and has achieved great results from the early "smart home" to "star computing" and "Internet of Things" solutions.

The software is guaranteed, but there are still many courses in hardware in China that need to be compensated first is the insufficient network bandwidth. Yang Xing pointed out at the meeting that one of the main reasons for the slow integration of IPV6 networks and three-networks is that domestic broadband construction is lagging behind. The most criticized thing about the domestic network environment is the slow network speed and high tariffs.

One of the purposes of the three-network convergence is to provide unified services through one network. To provide unified services, there must be a network platform that can support the transmission of various multimedia services such as audio and video. The characteristics of these services are that the service demand is large, the data volume is large, and the service quality requirements are high, so it generally requires very large bandwidth during transmission. In addition, from an economic perspective, the cost should not be too high. The current network bandwidth in China must not meet the requirements. This is also because although Xingdong Network has been quietly trying to migrate platforms such as main servers to the country, due to the slow progress of domestic network speed and other large environments such as low network speed, the main network operation centers still need to rely on US and European data centers such as Silicon Valley in the United States and Ireland.

Yang Xing took himself as an example. When he used Wimax to experiment with wireless high-speed Internet access in the United States 2,000 years ago, he encountered situations such as slow internet speed and inability to on-demand videos. But now this has basically become history. The third largest Internet ISP service provider under StarDong Network, the United States, just launched an annual fiber optic home purchase event of more than 2m not long ago, and the Internet fee is almost the same as in China.

Visiting scholars who just returned from the United States also pointed out that they are now inquiring about information in major American universities and public libraries, and they click and open it immediately, without any delay. In contrast, China Unicom has only launched an adsl service based on telephone lines. The 560k annual package is indeed a big step forward compared to the previous 56k phone dial-up Internet access, but it is extremely ashamed to compare the level of foreign peers horizontally.

The domestic official responsible for network construction talked about the achievements of visiting the network construction of neighboring South Korea not long ago, which made the Internet companies present feel uncomfortable. After the financial crisis in 1998, the South Korean government set the idea of ​​"serving the country with the information industry" and vigorously supported the information industry as the core industry of the country. One of the important ones is to vigorously improve the speed of domestic Internet access. Now it has surpassed the teacher Japan, but it has also passed the United States and ranked first among the fastest-speed countries in the world. In addition, experts and scholars have also found Hong Kong, which is only separated from the country by a wall. After Yang Xing acquired Hong Kong Telecom, he vigorously promoted the network laying of Hong Kong Island. The project of submarine intercontinental cable connecting Europe and the United States, which was completed not long ago, has made Hong Kong's Internet speed tied with Japan, the world's second place.

At present, the main body of broadband technology is fiber optic communication technology. Large-capacity fiber optic communication technology with huge capacity and sustainable development is the best choice for transmission medium to expand network bandwidth. The development of optical communication technology, as the pillar technology in the field of contemporary communications, is developing at a rate of 100 times every 10 years. The fiber optic transmission network with huge capacity is the ideal transmission platform for the "three networks" and the main physical carrier of future information highways.

The development of broadband technology, especially optical communication technology, provides the necessary bandwidth for transmitting various business information, high-quality transmission quality and low cost. At present, whether it is the telecommunications network, computer network, radio and television network, and large-capacity optical fiber communication technology have been widely used in it. In this regard, Yang Xing made an early arrangement. The joint venture optical fiber factory established with Jiudu Glass Group is now the world's largest production line, and now actively promotes the domestic ftth solution to find new customers for his products.
