Problems for IPv6 commercial networks

The main difficulty and bottleneck of IPv6 commercial network construction in China is how the construction of IPv6 network can bring direct or indirect benefits to operators, that is, how operators can withdraw their investment as soon as possible. At present, no key applications must be implemented on IPv6 instead of IPv4. These applications can be found and discovered only through large-scale experiments. Once these applications are found, the construction of IPv6 commercial networks will be quickly rolled out. There are a large number of IPv4 network devices and a large amount of resources on the IPv4 network, which also causes operators to dare not build large-scale IPv6 commercial networks.

Japan and South Korea are dominant in terms of IPv6 protocol. Since they developed it a little earlier, their product maturity has been improved in their testing network and even commercial network applications. Because the development of domestic devices lags behind Japanese and Korean manufacturers, there are few applications in the test network, and the products have not undergone real tests. In this case, on the one hand, domestic manufacturers should accelerate the research and development of IPv6 network products, on the other hand, they should also be applied in several large IPv6 test networks organized by the State as soon as possible, accelerate Product maturity in applications. At the same time, because the major domestic router manufacturers are better at IPv4 performance and product maturity than Japanese and South Korean manufacturers, if there is more investment in IPv6 R & D and productization, I think it will soon catch up with Japanese and Korean manufacturers.

China Unicom's IPv6-based urban backbone network is part of the CNGI project of China's next-generation Internet demonstration project. Other major carriers and CERNET have also participated in the network construction of the project.

This project will greatly promote the construction of IPv6 networks in China and the application of IPv6 in China. However, the main purpose of the project in the early stage was to use scientific research, education, and other research applications. Some tests were also conducted on some commercial applications. However, there is still a way to go before commercial use. That is to say, next year, China's IPv6 network will basically be a research-oriented experimental network, or a trial network that will work towards the IPv6 commercial network. It may take two years to upgrade or update a large-scale IPv6 network.

With the development of mobile networks and the evolution of 3G and 4G networks, more and more addresses are required for mobile networks and terminals. Currently, private address solutions commonly used in second-generation mobile networks, such as GSM and CDMA, are increasingly showing their limitations. This restricts the large-scale popularization of mobile data services.

The wide application of IPv6 will play a major role in the richness of NGN terminals. In the future, mobile computing technologies such as mobile phones, PDAs, and laptops will be widely and flexibly used after IPv6 is introduced. The introduction of IPv6 in the home network and office network will increase the application of the network to a new height. This may lead to many revolutionary applications.

The main technical challenge for IPv6 network construction is that IPv6 applications can support large-scale commercial applications only on IPv6 networks. This type of application requires a large number of IP addresses or a large number of fixed IP addresses. I personally think this type of application should be different from the current typical web application, but a real end-to-end application. That is to say, this application requires each host to have a fixed IP address, or each person has a unique ID number on the Internet. Other people can find it at any time based on the fixed IP address or ID number, and communicate with him.

In the case of many uncertainties in the 3G test, I personally think that IPv6 will be used in some large-scale applications based on broadband MAN or WLAN. However, with the development of 3G Testing and the construction of 3G networks, the demand for IPv6 networks will become increasingly strong.

In addition, the next-generation Internet and next-generation telecommunication networks will gradually integrate with each other under the unified IPv6 protocol.
