Embodiment Construction

[0021] Through the analysis and research of the prior art, the inventor found that the IP address allocation method used in the prior art has defects, that is, the IP address allocation method is not flexible enough, which leads to idle waste of IP addresses or tight supply of IP addresses. In order to solve this problem, the embodiment of the present invention provides a relatively flexible IP address allocation method. In this method, the inventor uses the master-slave IP address pool technology to unify addresses by adding an address pool convergence device as the user's DHCP server. The pool aggregation device assigns IP addresses to users; at the same time, the user's portal authentication is forwarded by the AC at Layer 2. In this way, users can share address pool resources, simplify maintenance and deployment difficulties, and avoid the problems of idle waste of IP addresses or tight supply of IP addresses in the prior art.

Abstract

The invention discloses a method and device for allocating IP addresses, which are used to solve the problems of idle waste of IP addresses or shortage of IP address supply in the prior art. The method includes: the address pool converging device receives the DHCP request transparently transmitted by the access controller AC, and the address pool converging device judges whether the IP addresses in the primary IP address pool stored by itself have been allocated. If the allocation is not complete, obtain the IP address from the primary IP address pool, and send the information of the obtained IP address to the user; if the allocation is complete, obtain the IP address from the secondary IP address pool, and send the obtained IP address The address information is sent to the user.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a method and device for allocating IP addresses. Background technique [0002] Dynamic Host Configuration Protocol (DHCP) is a LAN network protocol. Two computers connected to the Internet must have their own IP addresses to communicate with each other. Due to limited IP address resources, broadband access operators cannot assign a fixed IP address to each broadband user. , so it is necessary to use DHCP to assign temporary addresses to Internet users. [0003] In the existing networking scheme, the Access Controller (AC) is the user portal authentication gateway device, and at the same time, it will serve as the DHCP server to assign the corresponding IP address to the user (usually the IP address of the C network segment). User packets of the same Virtual Local Area Network (VLAN) / hotspot are terminated on the same Layer 3 interface of the AC, and different users acces...
