PPPOE (Point-to-Point Protocol over Ethernet)-based Intranet-Extranet uniform authentication method and device

Abstract

The invention discloses a PPPOE (Point-to-Point Protocol over Ethernet)-based Intranet-Extranet uniform authentication method, which is used for accessing a server side. The method comprises the following steps: when PPPOE authentication initiated by a client is received, sending an authentication request message to a first authentication server, wherein the authentication request message carries user authentication information in order that the first authentication server authenticates the user authentication information and transmits the authentication request message to a second authentication server in a transparent way after pass of the authentication, and the second authentication server continues authentication; receiving an authentication pass message returned by the first authentication server, and judging whether the authentication pass message carries a public network IP (Internet Protocol) allocated to an access client or not; and if so, allocating the public network IP to the access client. Through application of the method in the embodiment of the invention, a campus network user can access campus network Intranet and Extranet resources through one-time authentication, so that the campus network user can access the Internet resources more conveniently.

Description

technical field [0001] This application relates to the technical field of network communication, and especially designs a method and device for unified authentication of internal and external networks based on PPPOE. Background technique [0002] The campus network is a broadband local area network with interactive functions. Therefore, when users access the campus network, they need to perform user authentication just like when accessing the Internet. At present, campus network users need to distinguish between internal and external network users, and most campus networks use secondary authentication to distinguish between internal and external network users. When campus network users access the campus network, they need to use the internal network access authentication method for authentication, such as 802.1x access authentication; when campus network users access the external network, the internal network access authentication must be successful before using the external...

AI Technical Summary

Problems solved by technology

[0003] When campus network users want to access the external network, they need to pass two access authentications. First, the internal network authentication is required. After the internal network authentication is successful, they can access the external network. Therefore, it is very inconvenient for internal network users to access external Internet resources.
