In the past decade, ATM has become an important technology for next-generation networks. It provides unprecedented scalability and cost-effectiveness, as well as support for real-time and multimedia services in the future. In the future information system, ATM will play an important role. However, the current information system, LAN and WAN, is built on network layer protocols such as IP, IPX, and AppleTalk. Therefore, the key to the success of ATM an

The IP-based Internet has developed into the world's largest communication network with the largest number of users and the widest range of resources. Therefore, the IP protocol has become a de facto industry standard. The network based on the IP protocol has become the mainstream of communication networks. Based on the practical experience of the author and the

I. IntroductionIf the "Millennium Bug" problem is a major hidden danger in the development of computer technology, the problem of IPv4 address insufficiency is a "stumbling block" in the Development of China's IP technology ". The difference is that when the computer's date space was not enough and the millennium worm was about to appear, all countries in the world were eager to find a solution. Now, the problem that IPv4

With the development of China's routing industry, it also promotes the improvement of router protocols. The TCP/IP-based Internet has gradually developed into a super-large computer network with the largest number of users and the largest resources in the world. Therefore, TCP/IP has become a de facto industrial standard. IP networks are gradually becoming the ma
