Management method of user's connection to network in wideband network

Abstract

The invention discloses a method for managing user Internet connection in a broadband network, and solves the security problem in the broadband network. The invention is to establish permanent virtual connection (PVC) information or virtual local area network (VLANID), user account, ( Combination correspondence table between IP address and media access control (MAC) address; when the user accesses the Internet, judge the permanent virtual connection (PVC) information or virtual local area network (VLANID), user account, (IP) in the user's physical link information Whether the corresponding relationship between the address and the media access control (MAC) address is consistent with the information in the corresponding relationship table; if consistent, set up the online connection of the user; if inconsistent, refuse to set up the online connection of the user, which has the function of preventing illegal users Internet access, the ability to identify illegal attacks and other functions.

Description

technical field [0001] The invention relates to a method for managing users in a broadband network, in particular to a method for managing users' online connections by establishing the correspondence between permanent virtual connection PVC information in user physical link information or virtual local area network identification VLANID and user accounts. Background technique [0002] In the existing broadband network, it can be divided into ADSL access and Ethernet access according to different access technologies used by users to access the Internet. In a broadband network using ADSL access mode, the operator or ISP assigns a corresponding physical link to a user, that is, the permanent virtual connection PVC. The data frame sent by the ADSL user passes through this physical link and reaches the broadband network. The broadband access server BRAS strips off the link layer information, and then forwards the IP packets accordingly. The processing flow is as follows: figure ...

AI Technical Summary

Problems solved by technology

However, there are network security problems such as the inability to prevent illegal users from accessing the Internet, theft of network resources, and the lack of traceability functions after users are attacked.
