Embodiment Construction

[0028] Embodiments of the invention. Active IP address allocation systems such as figure 1 As shown, the composition of the system includes,

[0029] A client module 1 for network connection, a server 2 for IP address allocation and user attribute data storage, a network control module 3 for detecting user attribute data and corresponding IP addresses and controlling the network connection attributes of the client.

[0030] Described client module 1 adopts PPPOE network connection functional module, wherein functional module also comprises user attribute data acquisition, data encryption and data transmission module, disconnects the connection interruption module of server 2 temporary connections, regularly sends user attribute data and corresponding Synchronization module of IP address data. It can also include a mandatory synchronization module for forcibly changing the IP address of the client module to the bound IP address, so that the IP address can be directly changed ...

Abstract

The invention discloses an active IP address distribution method and a system, which is characterized in that: data of user properties is stored in a server; a fixed IP address is correspondingly distributed to each user property; a client is connected with a network by a PPPOE; the server distributes temporary IP addresses and is connected with the client; then the server authenticates the user properties at the client, finds out the IP addresses corresponding to the user properties and gives the IP addresses to client equipment; finally the client cuts off the temporary connection with the server. The correspondence and binding of the user properties and the IP addresses are compulsorily carried out by the method and system of the invention, the server carries out uniform distribution and active administration of the IP addresses, which can solve the problems of the arbitrary changes of IP and MAC of users, random distribution of PPPOE service, user identity confirmation, and original address authentication, etc.; the position, management and control of the IP addresses, various extended management, user tracking and compulsory identity authentication can be conveniently realized.

Description

technical field [0001] The invention relates to an active IP address allocation method and system, belonging to the technical field of IP address allocation. Background technique [0002] In the prior art, there are mainly the following three methods for assigning IP addresses: [0003] Fixed IP mode - use IP address + MAC address binding [0004] DHCP method - use random allocation method [0005] PPPOE mode - use PPPOE dial-up mode [0006] The comparison of the three allocation methods is as follows: [0007] project Fixed IP DHCP PPPOE address allocation fixed randomly Dial to obtain to bind IP+MAC can't can't user modification free randomly system IP conflict happen anytime Won't Won't system conflict happen anytime happen anytime Won't bandwidth loss Won't Won't 40% loss agreement TCP / IP DHCP PPPOE ...
