Why IPv6 technology is necessary

Upgrading is a necessary process for every thing, just like the current Internet. It is also facing an innovation, that is, the conversion from IPv4 to IPv6 protocol technology. Why should we use IPv6 protocol technology? Why is it next-generation Internet? Now let's discuss the relevant topics.

The grim fact makes people realize that IPv6 will be an excellent opportunity to change old rules and redraw the starting line. The purpose of the Internet Engineering Task Team to develop a new generation of Internet IPv6 protocol technical standards is to replace the 20-year-old IPv4 standard, so as to completely solve the problem of address depletion? Break the bottleneck restricting Internet development. IPv6 becomes the key to the development of the next generation Internet.

Compared with the existing Internet protocol IPv4, the next-generation Internet Protocol IPv6 has great advantages in terms of IP address volume, security, mobility, and service quality, drawing a beautiful blueprint for people's future information life.

The ultimate replacement of IPv4 by IPv6 is the trend of the times. almost unlimited address capacity is the most direct reason for IPv6 development. In the future, the devices used for new business requirements such as interactive multimedia, home networks, and terminals are always online. Therefore, each device requires a unique permanent IP address. The IPv6 128-bit address format supports 1 billion square meters of IP addresses. "It is enough to assign an IP address to each sand on the earth ", this will fundamentally solve the problem of insufficient IP addresses and create preconditions for carriers to provide various "killer applications" on the next-generation Internet. An IPv6 car has been developed in Japan, and an IP address is assigned to the wipers, engines, and tires of the car. The wiper is a weather sensor, and the engine is used to detect the performance of cars. The tires are used for speed inspection-IPv6 technology, which will bring more diverse applications to people's lives in the future.

At the same time, security issues are inherent defects that cannot be avoided by the existing Internet protocol IPv4. Because the Internet was initially designed for military and scientific research purposes and is not open to the outside world, there is no comprehensive consideration for network security issues. With the wide use of the Internet in various fields of social life and the proliferation of hackers and viruses, security issues have increasingly become the focus of attention. In terms of security, IPv6 is consistent with the IP Security Mechanism and service. In addition to the mandatory network layer security mechanism, IPv6 also provides two services: authentication header and encapsulated Security load header. Compared with the existing Internet protocol IPv4, it can provide more secure protection for people's information life.

It is worth mentioning that the integration of 3G and Internet is considered one of the future development trends in the development of mobile communication. To access the internet anytime and anywhere on a mobile terminal, you must assign a Global IP address to each mobile terminal. However, the existing IPv4 address is far from enough. The combination of IPv6 and mobile communication will open up a new field-mobile Internet. Wireless will become the first "killer application" of IPv6 ".

Last year, the 3G Standardization Organization 3GPP decided to build the next-generation mobile communication network based on IPv6, which greatly stimulated the R & D enthusiasm of Mobile Manufacturers. If the development of 3G promotes the development and standardization of IPv6, the advantages of IPv6 provide a broad prospect for the comprehensive application of 3G networks. The IPv6 protocol features a huge address space, good support for mobility, service quality assurance mechanism, security, and automatic Address Allocation Mechanism, which can meet the needs of 3G networks, it will be the root of 3G mobile communication.

In addition, IPv6 has unparalleled advantages in supporting "always online" connections, preventing service interruptions and improving network performance. In addition, better network and service quality improves customer expectations and satisfaction, enhance the competitiveness of enterprises. For users, excellent network communication quality and good network performance undoubtedly have greater advantages in rich content applications.

IPv6 has both opportunities and challenges. Although twists and turns are long, it has bright prospects.

As an Internet and mobile communication power, taking the initiative in the Next Generation Internet standards and resource allocation is currently the top priority of China's information industry development. As the core technology of the Internet, IPv6 will drive the development of a large number of related technologies and services, enhance the overall strength of the information industry, and bring new development opportunities to China's information industry. Moreover, with the changes in the competition mechanism of China's information industry, operators began to shift from mere scale competition to business service competition. IPv6 provides a huge address space and many advantages and functions, making it an important foundation for building the next generation network and a powerful tool for operators to "attack the city and pull the village" in the communication market.

Nowadays, the next generation network with IPv6 as the core technology is becoming more and more important in China, and it will play an important role in the development of high-quality and diversified future communication services.

Although we all realize that IPv6 technology represents the correct direction of Internet development, replacing IPv4 is an irreversible trend, but its development process is not smooth sailing. It will be a project with a long return period and a huge investment. All links in the industry chain, including operators and equipment manufacturers, cannot ignore the huge business opportunities brought about by this opportunity. What we need to do is to speed up IPv6 network construction, constantly improve its shortcomings, and explore its new applications to gradually replace the current IPv4 network.
