Method, system and apparatus for creating a mesh network of wireless switches to support layer 3 roaming in wireless local area networks (wlans)

Abstract

Techniques are provided for techniques are provided for creating a mesh network in wireless local area network comprising a plurality of wireless switches. An IP address of the registration server can be configured on each of the wireless switches and used to open an IP socket from each of the wireless switches to the registration server. Each of the wireless switches register with a registration server by communicating configuration information about each of the wireless switches to the registration server. In one implementation, the configuration information for each switch comprises a switch IP address and a list of subnets the switch supports. The configuration information can be used by the registration server to create a wireless switch list which includes a listing of each of the wireless the switches in the wireless local area network. The configuration information about each of the wireless switches and the wireless switch list can then be communicated to each of the wireless switches. Each wireless switch can use the configuration information from each of the other wireless switches to create a mesh network of wireless switches. In one implementation, each of the wireless switches can use the configuration information and the wireless switch list to open a UDP/IP socket to each of the other wireless switches.
