The purpose of this in the early days of the development of the Internet is to avoid the risk of war, which makes the cruel war destroy the information transmission channels of the military. Theoretically, any computer workstation or Internet must connect nodes with the outside through several regional centers, so as to avoid communication interruption caused by the damage of some nodes. Therefore, the distribution of the Internet is characterized by "scattered thoughts and prevention of centralization", and only decentralization will prevent them from becoming a pot. The Internet in China can be micro-structured. On the one hand, the nodes connected with the international community are very small. Once they are destroyed, our networking with the international community will be blocked or interrupted.
