Problems solved by technology

[0010] 3) Service policy, so that users can only access internal servers such as Portal Server and individual external servers such as DNS
[0025] Although the method for secondary IP address distribution has solved the dependence on the access control list (ACL) in the primary address distribution method, it still does not solve the problem of anti-counterfeiting DHCP server
The disadvantage of this method is that the amount of network construction is large, and it has high requirements for the load of network equipment.

Embodiment Construction

[0038] The access system of the broadband network user access management method of the present invention is divided into two parts, a server end and a client end, and is a software system with a distributed architecture.

[0039] 1. The server program part

[0040] The server program includes: DHCP server, session server (server program supporting ECP session protocol), task distribution module, router management module, router control module, authorization (AUTHORIZATION) module, authentication (AUTHENTICATION) module, duration acquisition module and monitoring module.

[0041] in:

[0042] a)DHCP server

[0043] The function of the module: DHCP is weakened into a receiver to receive DHCP requests, and the specific allocation operation is completed by the authentication and authorization module.

[0044] b) session server

[0045] The session server realizes the transmission of authentication and authorization information between the client program and the server program, ...

Abstract

In addition to getting IP addresses through DHCP protocol, a client side software program and a serving side software program used by the method also keeps a communication session for used in accurately detecting the status information of client side such as: on line and off line information. The method features: the client side can initiates a DHCP request to alter IP address not depending the stipulation of address- reletting specified in the DHCP protocol; and meanwhile when the client side initiates the first and second request, it can identify the legal and illegal DHCP server according to the network attribute carried in DHCP message returned by the server, and only responds to legal server.

Description

technical field [0001] The invention relates to computer network technology, in particular to a broadband network user access management method. Background technique [0002] The DHCP protocol is derived from the LAN application. Currently, there are three main ways to use the DHCP protocol for broadband management in a carrier-class network: (1) DHCP extension protocol; (2) DHCP+Web, of which: [0003] 1. DHCP extension protocol [0004] Specification documents such as RFC-2132 and RFC3118 stipulate that extended attributes of the DHCP protocol are used to carry user identity information, thereby realizing authentication and authorization of users. However, the four messages and their working principles formulated in the DHCP protocol cannot effectively and precisely solve the identification and control of the user's online status. Therefore, it is difficult to realize accurate billing for users in this method. So far, the DHCP extension protocol has not been successful ...
