Authentication processing method for broadband network

Abstract

The invention supplies a method to process identification in wide band network. Its core is that: recording the address data of the online network terminal; when receiving the identification request text from network terminal, capturing the address information of the terminal; comparing the information with the recorded information and record the terminal that matched the recorded address information; taking identification to the network terminal according to the identification request text of network terminal that matched with the address information. The invention improves the reliability of identification process, decreases the potential threat of the network device.

Description

Technical field [0001] The invention relates to the technical field of network communication, in particular to a method of authentication processing in a broadband network. Background technique [0002] With the development of broadband networks, it has become a popular phenomenon for network terminals to access broadband networks through broadband access services and access INTERNET through broadband networks. The schematic diagram of the network terminal accessing the broadband network through the broadband access service is as attached figure 1 Shown. [0003] in figure 1 Among them, BNAS (Broadband Network Access Server) is a broadband access control device located between the network terminal and the Internet, and the AAA (Authorization, Authentication, Accounting) server provides functions such as authorization, authentication, and accounting for the network terminal. The network terminal accesses the broadband network through broadband access methods such as xDSL (x digi...

AI Technical Summary

Problems solved by technology

[0010] 2. After the network terminal passes the authentication and goes online normally, BNAS has abnormal phenomena such as restarting, and the status of each network terminal in BNAS is all lost, and BNAS does not send the accounting stop message of each network terminal in the lost state to the AAA server

[0011] 3. When the network terminal passes the authentication, goes online normally, and goes offline normally, the AAA server cannot receive the accounting stop message of the network terminal sent by the BNAS due to an abnormality in the network between the BNAS and the AAA server. After the network with the AAA server is restored, BNAS will not resend the accounting stop message of the network terminal

[0012] 4. When the network terminal passes the authentication, goes online normally, and goes offline normally, the AAA server cannot correctly process the billing stop message sent by the network terminal sent by the BNAS due to phenomena such as restarting the AAA server, abnormal database, etc. After the AAA server returns to normal, BNAS will not resend the accounting stop message of the network terminal, and the AAA server will not reprocess the accounting stop message of the network terminal

Using this method will also bring a new problem, when the network between BNAS and AAA server has a short-term abnormality, such as the loss of some intermediate accounting packets, but the network terminal, BNAS and AAA server are not abnormal In some cases, this method will cause the network terminal to be forced to go offline abnormally

[0026] To sum up, when the AAA server authenticates the network terminal, the detection method provided by the existing technology cannot timely and accurately detect whether the network terminal is hanged, resulting in poor reliability of the AAA authentication process, making normal The network terminals cannot access the Internet normally; and the AAA server concentrates on processing a large number of hanged network terminals, occupying a large amount of network resources in a short time, increasing the potential threat of network equipment and increasing the potential cost of network equipment authentication processing
