The IPv6 protocol will be an important protocol for NGI (Next Generation Internet). At present, the basic standards of the IPv6 protocol are gradually mature, and various types of network devices supporting IPv6 stand out and gradually apply to the commercial. In terms of operations, many foreign telecom operators have set up IPv6 networks, and have begun to provide value-added services and access services based on IPv6. China has also started the construction of CNGI (Next Generation Internet), which has greatly promoted the development and popularization of NGI in China. Therefore, under the condition that the network conditions are basically mature, the next generation Internet must succeed in developing new services for users and create new value for telecom operators.
With the gradual depletion of IPv4 address resources, the requirements for network security and network service quality continue to increase. The major countries in the world have fully realized the urgency and importance of deploying IPv6 at this stage. Governments have introduced national development strategies and formulated clear developments. Roadmaps and timelines to actively promote large-scale commercial deployment of IPv6.
The European Union issued the “European Deployment IPv6 Action Plan†as early as 2008, requiring timely, efficient and coordinated action in Europe to promote the migration of EU enterprises, government departments and household users to IPv6 in phases. October 2009 Japan issued the "IPv6 Action Plan" and decided to launch IPv6 services from April 2011. Currently, 11 ISPs provide IPv6 commercial services. In September 2010, the US government issued an IPv6 action plan. In July 2012, the US government updated the “Government IPv6 Application Guide/Planning Roadmapâ€, clearly requiring that by the end of 2012, all Internet public services provided by the government must support IPv6; At the end of 2014, the government's internal office network fully supported IPv6. In September 2010, South Korea released the “Next Generation Internet Protocol (IPv6) Promotion Planâ€, announcing that since June 2011, domestic Internet, IPTV, 3G mobile communication and other services have been completed. IPv6 will be supported. In June 2012, the Canadian government issued the “Canadian Government IPv6 Strategyâ€, which requires the completion of IPv6 upgrades of existing websites by the end of March 2015, and requires all new Internet websites and applications to support IPv6. In addition, Brazil, India, Australia, Singapore, Malaysia and other countries have also proposed IPv6 development strategy plans to promote the commercial deployment of IPv6.
2010 is the first year of IPv6 commercial use in China. Driven by the guidance of national policies and the new generation of information technology industries such as broadband network, mobile Internet, Internet of Things, triple play and cloud computing, the commercial process of IPv6 in China is gradually accelerating. The first generation of the Internet has gradually shifted from trial and demonstration to trial and commercial use.
IPv6 has made great progress in China. It has not only taken a critical step in the deployment of trial commercialization, but the industry chain is gradually improving and maturing. Huawei, ZTE, Campfire, Maipu and other enterprises have emerged, and key devices such as network equipment have been launched. Technology has reached the international advanced level.
IPv6 applicationHowever, for the majority of ordinary users, the most concerned is still the application. The biggest application highlights of IPv6 are the mass address, stateless autoconfiguration, and mobile IPv6 features. Therefore, IPv6 applications mainly have the following aspects:
IPv6 and triple-play
According to the nature of the business, triple-play (triple service) mainly includes three types of telecommunication services: high-speed data service, high-quality video service and basic voice service. According to the receiving medium, it mainly includes computer-based and TV-based services and voice services. As the triple service of telecom operators continues to evolve, more services and devices are transformed into IP transmissions, which requires more network addresses and requires the network to be plug and play, and IPv6 just meets these needs.
IPv6 and RFID
Radio Frequency Identification (RFID) is a technology that automatically recognizes without contact. It uses RF signals to automatically identify target objects and obtain relevant data without human intervention. RFID is a wireless version of bar code. It has the advantages of high temperature resistance, anti-magnetic, waterproof, long service life, large storage capacity, encryption of tag data, large reading distance, convenient storage data change, etc. Industries such as retail have brought about tremendous changes. Because IPv6 has a huge address space, it is more suitable for RFID. These sufficient addresses can meet the address requirements of each RFID, which is difficult for IPv4 with lack of address resources.
IPv6 and Wi-Max, Wi-Fi
Both Wi-Max and Wi-Fi will promote the adoption of IPv6. With the continuous development of Wi-Max and Wi-Fi, there will be more and more requirements for IP addresses, which will promote the development of IPv6, and the new features of IPv6 will greatly facilitate the implementation of these applications and technologies, not only to meet the requirements. A large number of address spaces, and IPv6 has the characteristics of plug-and-play such as end-to-end communication without NAT, which lays a good foundation for the development of these applications and technologies.
Video Surveillance
IPv6 brings a huge amount of addresses, and it is possible to deploy a large number of web cameras, and it is easy to manage and control. Through the support of the IPv6 protocol, the network camera terminal has more vitality. From the foreign video surveillance market, it can be seen that individual users are also important customers of video surveillance, while video surveillance in China is mainly concentrated in industry users, and has great potential for development in individual users. Video surveillance has begun to show its vitality, and the large-scale, operational monitoring network provides operators with a wide range of business opportunities.
Intelligent terminal, Internet of Things
With the integration of personal terminals such as PDAs and smart phones into the Internet, more and more electronic devices have the need for networking functions, including: personal smart terminals, industrial sensors, vending machines, automobiles, etc., which will generate huge The need for an IP address. IPv6's "plug and play" address allocation method and huge address space can meet the needs of intelligent terminals.
Smart home network
With the rapid development of the Internet, the concept of "home network" is quiet, but because of the lack of address resources in IPv4, if there are a large number of information appliances that need to access the network through the gateway, IPv4 does not have enough addresses for each An information appliance allocates a separate address and can only use the private address, NAT and other technologies to overcome this shortcoming, but the management and setting are very complicated, hindering users from accepting new technologies. But IPv6 does not have a situation like this.
The home network based on CNGI is a research hotspot. In the future, the home network will include diversified components such as smart home appliances, streaming media application systems, video surveillance systems, and home control systems, integrating communication, entertainment, and control. Combined with IPv6 technology, the deployment of smart home networks can be more conveniently implemented.
