1. Access mode of educational network: CERNET basically has the networking ability to connect most universities in China, and has completed the upgrading and expansion of CERNET's eight regional backbone networks, and built a large-scale national educational information search system.
2. Access mode of public network: The IP address obtained by computers accessing the Internet is a non-reserved address on the Internet, and computers in public network and other computers on the Internet can access each other at will.
Second, the relevant requirements of the two are different:
1. Requirements related to education network: With the development and application of the information platform of the education system, according to the 12th Five-Year Plan of the Ministry of Education, the new generation of education network will inevitably become the foundation of future education informatization. The quality education cloud platform of Asia Education Network is the first intelligent education cloud platform in China to realize the integration of three networks and the cross-platform use of Internet, telecommunication network and radio and television network.
2. Requirements related to public network: In a local area network, only one computer needs to connect to the Internet, so that NAT can be used to share the Internet connection, so that other computers in the local area network can also access the Internet. Using NAT protocol, computers in the local area network can access computers on the Internet, but computers on the Internet cannot access computers in the local area network.
Third, the essence of the two is different:
1. The essence of the education network: IP addresses within the Ministry of Education are allowed to access, but foreign networks are not.
2. The essence of public network: Internet connection sharing of Windows operating system, sygate, winroute and natd of unix/linux all use NAT protocol to share Internet connection. Almost all Internet access methods provided by ISP are based on NAT protocol.
