Method and device of address distribution

Abstract

The present invention discloses a method and device of address distribution. The method comprises: the type of message is determined when an AP receives the message from a wireless client; if the type of the message is DHCP request message, the AP perform tunnel encapsulation of the DHCP request message, and the DHCP request message after tunnel encapsulation is sent to an AC; and when the AP receives a DHCP response message returned by the AC, the DHCP response message is subjected to tunnel decapsulation, and the DHCP response message after tunnel decapsulation is sent to the wireless client, wherein the DHCP response message after tunnel decapsulation carries address information distributed by the AC. In the embodiment of the invention, the uniqueness of the IP address of each wireless client may be guaranteed, so that the problem of repeated IP addresses of a plurality of wireless clients is avoided and the interference on an authentication system and the occurrence of authentication errors are avoided.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to an address allocation method and equipment. Background technique [0002] Such as figure 1 As shown, it is a schematic diagram of networking of a Wi-Fi (Wireless Fidelity, wireless fidelity) hotspot based on a cloud platform. Different user networks are located in different regions, and are uniformly managed by the cloud platform. Among them, the cloud platform is a set of software systems running in the data center. The cloud platform is responsible for managing user networks distributed across the country, including configuration distribution, collection of various information to form a big data platform, and unified release of advertisements. In this application scenario, the cloud platform is responsible for centralized authentication of wireless clients, and the data traffic of wireless clients accessing the Internet is directly forwarded to the Internet by th...

Problems solved by technology

Furthermore, when the egress gateways in each user network assign IP addresses to wireless clients, it is difficult to coordinate with each other because the egress gateways are independent of each other, so multiple wireless clients may be assigned the same IP address

When these multiple wireless clients are authenticated on the cloud platform, because the multiple wireless clients have the same IP address, the cloud platform cannot distinguish between these multiple wireless clients, which will cause authentication errors
