DHCP renewal method and device, electronic equipment and machine readable storage medium

Abstract

The disclosure provides a DHCP (Dynamic Host Configuration Protocol) renewal method and device, electronic equipment and a machine readable storage medium. The method comprises the steps that a firstencryption renewal message sent by a first terminal is received, a first table item corresponding to the first terminal is established in a renewal confirmation table established in advance accordingto the message, wherein the table item of the renewal confirmation table comprises configuration information, and the configuration information of the first table item is default configuration; the first encrypted renewal message is forwarded to AAA equipment; a first authentication result message is sent by the AAA equipment, wherein the first authentication result message is generated after theAAA equipment analyzes the first encryption renewal message and performs authentication according to the analyzed information; and if the first authentication result message comprises authentication pass information and first configuration corresponding to the first terminal, the configuration information of the first table item is updated to be the first configuration, the IPOE table queried according to the first table item, and the contract for the first terminal is extended if a matched table item exists. According to the technical scheme of the invention, the method can achieve the reliable and safe renewal of the appointment for the terminal user, and the business cutoff can be avoided.

Description

Technical field [0001] The present disclosure relates to the field of communication technologies, and in particular, to a DHCP renewal method, device, electronic equipment, and machine-readable storage medium. Background technique [0002] DHCP (Dynamic Host Configuration Protocol, Dynamic Host Configuration Protocol) is a LAN network protocol, which refers to the IP (Internet Protocol, Internet Protocol) address range controlled by the server, and the client can automatically get the server allocation when logging in to the server IP address and subnet mask. [0003] BRAS (Broadband Remote Access Server, broadband access server) is a new access gateway for broadband network applications. It is located at the edge layer of the backbone network and can complete the data of the user bandwidth IP / ATM (Asynchronous Transfer Mode) network Access, realize broadband Internet access of the terminal, IP VPN (Virtual Private Network) service based on IPSec (IPSecurity Protocol), build intra...
