IPv6 and next-generation networks

In order to adapt to the rapid development of data services represented by IP Services and the trend that the data business volume will exceed or greatly exceed the voice business volume; to adapt to the changes in network traffic distribution caused by customer-server and other application methods, as well as the unique self-similarity of IP Services and the asymmetry of sending and receiving, to support an endless stream of online applications, all countries in the world are exploring and experimenting with sustainable next-generation networks. The emergence of the Next Generation Network NGN technology has led operators to invest in research and exploration of the Next Generation Network. At present, China's telecom operators have begun construction of the next-generation experimental network, and the next-generation network technology with Softswitch and IPv6 as the core is becoming increasingly mature, major domestic and foreign communication manufacturers have successively launched the next generation network products and technologies. With the development of business needs and technologies and the evolution of network architecture, the next generation network has become a hot topic in the development of communication networks.

Next-generation networks will be the world of IP networks, optical networks, and wireless networks. The Next Generation Network is an IP-based network, which has become a consensus in the industry. From the core network to the user terminal, information is transmitted in the form of IP addresses. In addition to the continuous development and popularization of various Internet applications, various traditional telecom services are also constantly shifting to IP-based networks. The demand for broadband development has ushered in the rapid development of optical communication. Optical Communication has now penetrated into all aspects of the network, from wide area networks, man networks, to local area networks; from Long-Distance Networks, domestic networks, access networks, to user resident networks, the development of the optical fiber broadband network provides a broad development prospect for the increasingly wide range of broadband applications. Wireless connection frees people from the limitations of cables and allows them to access communication and information services anytime and anywhere without being limited by geographical locations. The rapid development of mobile communication in the world in recent years also proves that mobile communication will gradually occupy the central stage of the traditional wired network and move the network from the ground to the radio waves in the air.
