Method for implementing conversation control and duration collection through DHCP extension

Abstract

The present invention relates to a method which utilizes the conversation controlling and the duration collecting by the DHCP enlarging(hereinafter SESSION DHCP for short). The cores of the present invention are as follows: the precise collections of the conversation maintaining as well as controlling and the online duration of the client are utilized based on the interaction of the DHCPREQUEST message and the DHCPACK message, the DHCPClient and the DHCPServer maintain a communicating conversation by the DHCP agreement message so as to accurately estimate and control whether the DHCPClien is on line and the states information of the logging in as well as the logging out time etc. The present invention is characterized in that: the maintenance of the communicating conversation is completedby the interaction of the standard message of the DHCP agreement, the present invention has no influence and particular requirements to all the devices which supporting the DHCP agreement and only changes as well as optimize the processing flow of the client ends and the serving ends. The present invention realizes the client controlling based on the functions of the conversation maintaining and controlling, and can effectively control as well as apperceive the total on line actions of the clients and realizes the precise duration collecting.

Description

Technical field [0001] The present invention relates to computer network technology, in particular to a method for authentication and management of broadband network user access. Background technique [0002] 1. DHCP protocol [0003] The DHCP protocol comes from LAN applications. The original purpose is to realize automatic address allocation and save addresses. Therefore, the DHCP protocol does not have any user control and management functions, and cannot realize secure authentication based on user name and password, and cannot realize accurate The collection of user time on the network cannot be directly used as a solution for user control and management of an operable access network; however, DHCP also inherently has a series of advantages such as flexibility in deployment independent of network topology. [0004] 2. PPP protocol [0005] The PPP protocol is currently one of the most widely used protocols on the WAN. Its advantages are simplicity, user authentication capabilitie...

AI Technical Summary

Problems solved by technology

[0008] The value of the present invention is to overcome the inherent defects that the standard DHCP protocol cannot perform perfect user identity authentication and user session control, and at the same time change the deployment and implementation of the network bottleneck of the PPP protocol in the traditional sense, making full use of the DHCP protocol The server deployment has the advantage of being irrelevant to the network topology, which meets the carrier-level application of broadband access network user authentication management. The specific features are as follows:
