Embodiment Construction

[0038] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. the embodiment. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0039] The core function of traditional BRAS: users apply for and access the network through specific methods. Common access methods include dial-up access, static IP access, dynamic DHCP access, and some complex access methods related to VPN. Introduce the first three methods.

[0040] The working process of the dial-up access mode is as follows:

[0041] The user uses the dial-up...

Abstract

The invention provides an IP address management and distribution method, device and system. The method comprises the following steps: acquiring preset IP address information, wherein the preset IP address information comprises multiple segments of IP addresses; determining a plurality of address pools according to the IP address information, wherein each address pool comprises multiple segments of preset IP addresses; marking a static address and a fixed address in the address pool, wherein the static address comprises an MAC address; generating an available address field according to the address pool, the static address and the fixed address; and when a user address allocation request message is received, allocating an IP address to the user according to the user address allocation request message, the MAC address, the address pool and the available address field to obtain an address allocation result. According to the embodiment of the invention, one virtualized BRAS can support multi-region and multi-network address pool allocation.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an IP address management and distribution method, device and system. Background technique [0002] Broadband Remote Access Server (BRAS for short) is a new type of access gateway for broadband network applications. It is located at the edge layer of the The means are mainly based on xDSL / Cable Modem / high-speed Ethernet technology (LAN) / wireless broadband data access (WLAN), etc.), to realize broadband Internet access for commercial buildings and residents in residential areas, IP VPN services based on IPSec (IP Security Protocol), and construction Intranet within the enterprise, support for ISP wholesale business to users and other applications, at present, a single BRAS cannot satisfy multi-region and multi-level address allocation, and more BRAS need to be configured, which consumes huge costs. [0003] After vBRAS (Virtual BRAS, virtual broadband remote access ...
