Sharing data between wireless switches system and method
First Claim
1. A system comprising:
- a plurality of wireless switches;
a plurality of respective sets of APs, wherein each of the respective sets of APs is coupled to a wireless switch of the plurality of wireless switches;
an AP ownership database, coupled to the plurality of wireless switches, including data indicating wireless switch ownership by each of the plurality of wireless switches of each of the respective sets of APs;
a plurality of contiguous radio domain databases, including wireless data, respectively associated with each of the plurality of wireless switches;
wherein, in operation, a first wireless switch of the plurality of wireless switches controls one or more of a first respective set of APs of the plurality of respective sets of APs to detect adjacent APs, accesses the AP ownership database to determine the owner of the adjacent APs, and updates a first contiguous radio domain database associated with the first wireless switch to include wireless data associated with each of the owners of the detected adjacent APs.

Abstract
A technique for facilitating the management of a wireless database related to station records and radio-frequency (RF) information by reducing unnecessary sharing of the data among wireless switches, thus enhancing efficiency in a wireless network. A system constructed according to the technique includes a collection of wireless switches with each switch having associated access points (AP), an AP database distributed throughout the collection of wireless switches, and at least one station radio frequency (RF) database. The AP database includes data associated with ownership of the AP'"'"'s by the switches, and the station RF database includes wireless station information and RF information. AP radio adjacency is determined by whether an AP owned by a specific switch can detect the other AP owned by another switch. The station and RF information database is shared only within the subset of switches that have AP radio adjacency.

14. A station radio-frequency (RF) database comprising:
-
a storage media; a data structure defined in the storage media and including a first field for storing a station information and a second field for storing an RF information; the station information including identification of any detected stations and location record; the RF information including an access-point (AP) information of a known AP, and an AP radio adjacency and optionally of an unknown AP, where the adjacency being determined by whether an AP owned by a specific switch can receive RF signals transmitted by the other AP owned by another switch. - View Dependent Claims (15, 16, 17)
