User identity binding and user identity binding assisting method and device

Abstract

The invention provides a user identity binding method and a corresponding device. The user identity binding method and the corresponding device are applied to a DHCP server and access equipment. The user identity binding method comprises the steps that a DHCP request transmitted by the access equipment and sent from a terminal is received, and user identity authentication information is obtained from the DHCP request; an IP address corresponding to the user identity authentication information is searched for in a preset user address list; if the IP address is not found, a corresponding IP address is selected for a user and the corresponding relationship between the user identity authentication information and the selected IP address is stored in the user address list; if the IP address is found, the IP address corresponding to the user is sent to the user terminal together with a DHCP response message. Compared with the prior art, the user identity binding method and the corresponding device avoid the configuration difference between private equipment and company equipment, and reduce the configuration complexity of upper-layer applications.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for user identity binding and a method and device for assisting user identity binding. Background technique [0002] DHCP (Dynamic Host Configuration Protocol, Dynamic Host Configuration Protocol) is a LAN network protocol, using a server / client architecture, and the DHCP server is mainly used to automatically assign configuration information such as IP addresses for DHCP clients. [0003] Option82 is called the relay agent information option, which records the location information of the DHCP client. After the DHCP relay device receives the request message sent by the DHCP client to the DHCP server, it adds Option82 to the message and forwards it to DHCP server. [0004] The process of automatically assigning IP addresses using the DHCP protocol is: the DHCP client sends a DHCP-DISCOVER message to find a DHCP server, and the DHCP server in the...

Problems solved by technology

[0005] At present, when users use their own terminal devices to access the company network, the company usually uses an authentication client to authenticate the user terminal devices. Since the users use their own devices, the administrator cannot identify the users through the MAC address or IP address.

However, upper-layer network applications, such as HTTP and flow control, cannot identify the identity of user terminals due to protocol restrictions. For this, administrators can only manage and monitor these user terminal devices through static configuration addresses or separate authentication and forwarding nodes. , on the one hand, it increases the deployment cost, on the other hand, it also increases the complexity of management
