Embodiment Construction

[0021] The overall logical structure of the network access intelligent control system of the present invention is as follows: figure 1 As shown: it includes terminal user computer 1, NAS server 2 (Network Access Server, network access server) and RADIUS server 3 (RADIUS, Remote Authentication DialIn User Service, remote dial-up user identity authentication and billing service protocol) connected in sequence in two directions . Terminal user computer 1 comprises terminal user interface module 11; NAS server 2 comprises three major modules: server user interface module 21, network resource access control subsystem 22 and RADIUS client module 23; Described server user interface module 21 is connected with terminal respectively The user interface module 11, the network resource access control subsystem 22, and the RADIUS client module 23 are bidirectionally connected. The RADIUS server 3 includes two parts connected bidirectionally: a RADIUS server module 31 and an authentication...

Abstract

The invention provides an intelligent control system for broadband network access, which is composed of a terminal user computer, a switch, a NAS server, and a RADIUS server. The user information is authenticated, and the NAS server controls whether the corresponding port of the switch is opened according to the authentication result. Allow the end-user computer (1) that has obtained the access right to directly access the Internet through this port. Adopting the above technical solution has the following advantages: high authentication efficiency; good flexibility; improved network performance; and wide applicability. At the same time, due to the use of RADIUS authentication server, it has the following advantages: after receiving no response within a certain period of time, it can immediately resend a UDP message without caring whether the previous message arrives; it better protects the confidentiality of data; The structure is simple and clear.

Description

technical field [0001] The invention relates to a method and control system for the security and management of an IP broadband network. Background technique [0002] With the further development of network technology, the narrowband network environment can no longer meet people's needs for network information, and broadband network construction has become a hot spot in network construction. In the development of broadband network, IP has occupied the dominant position of various terminal applications, and the security and management of IP broadband network have also become the focus of network development. Taking the campus network as an example, with the growth of network users and the complexity of business models, the original user management model gradually shows its limitations. The main problems focus on the theft of IP addresses, the increase of network security threats within the LAN, and the difficulty of network resource management. In addition, as more and more ...
