Embodiment Construction

[0054] Referring to Fig. 2, the method described in the embodiment of the present invention maintains user information by eavesdropping on ARP messages or DHCP (Dynamic Host Configuration Protocol, Dynamic Host Configuration Protocol) messages through the access controller AC, that is, maintains the MAC address of the user terminal Correspondence information between IP address and ARP request message; when there is an ARP request message, the AC will respond to the ARP request message instead of the user terminal according to the established user information, thereby solving the problem of the ARP request message on the AC. Broadcast copy problem, the specific process is as follows:

[0055] Step 201: the access controller establishes and maintains user information, that is, establishes and saves the corresponding relationship {IP, MAC} between the IP address and the MAC address of the user terminal. Here, the AC can eavesdrop on the ARP message from the user terminal, that is...

Abstract

This invention discloses one wireless local network address analysis agreement broadcasting method and its interface controller, which comprises the following steps: firstly, connecting controller and establishing and maintaining user information with the information for user end IP address and MAC address relationship; when controller achieves certain user address analysis agreement ARP message to extract ARP require message aim IP address; according to maintain user information finding aim IP address and relative MAC address to take place of user with MAC address ARP message.

Description

technical field [0001] The present invention relates to a wireless local area network broadcasting technology, in particular to a wireless local area network ARP (Address Resolution Protocol, Address Resolution Protocol) broadcasting method and an access controller. Background technique [0002] WLAN (Wireless Local Area Network) provides a wireless connection service for local area networks. Because it can provide high-speed wireless data access, WLAN is one of the more popular technologies in the IT industry at present, and it is also a popular wireless access method. A WLAN generally adopts a centralized AC-AP (Access Controller-Access Point, Access Controller-Access Point) architecture. Among them, the AC provides centralized management of the WLAN network, and the AP establishes a link with the AC and joins the WLAN network to provide wireless access services. [0003] There are mainly two ways of WLAN centralized architecture: Local (local) way and Split (split) way. ...
