Access method of distributed internet

Abstract

The invention provides an access method of a distributed internet based on word command two-way authentication. The method comprises the following steps of: detecting NAT (Network Address Translator) types of the internet in which the terminal is positioned by using a plurality of servers; then requesting a query server list from a proxy server; and finally, transmitting an authentication requestto a query server and acquiring public network IP (Internet Protocol) and ports of terminals, which are registered in the current query server after the authentication is successful, thereby finishing the access process. According to the method, the burden of the servers is reduced and the query efficiency and the stability of the system are improved by adopting a distributed query scheme. In addition, the invention can prevent the query servers from being attacked by illegal terminals.

Description

technical field [0001] The invention relates to the technology in the field of network communication, in particular to a distributed Internet access method based on password bidirectional authentication. Background technique [0002] The widespread popularization of Internet technology has led to a shortage of public network IP addresses, especially the shortage of Class C addresses. At present, the allocation of IP addresses mainly includes two methods: one is the way of dial-up Internet access. When home terminals use ADSL dial-up Internet access, China Telecom dynamically allocates public network IP addresses for such terminals; the second way is to allocate fixed public IP addresses. Network IP address, this method is mainly used in enterprises. But either way, the limited class C public network IP address resources cannot meet the needs of terminals. Therefore, in order to solve this problem, it is necessary to convert the existing network addresses. [0003] Network...

Problems solved by technology

[0006] 1 Concentrating queries on one server will waste a lot of bandwidth, increase the burden on the server, increase the number of mapping entries in NAT, and reduce query efficiency;

[0007] 2. If the main server encounters a network interruption, the entire query service will fail;

[0008] 3 The query server is vulnerable to attacks from illegal terminals
