Abstract

According to one embodiment of the invention, a method for synchronizing access points in a wireless network includes determining a service set identifier of a selected access point in the wireless network. The service set identifier identifies a name of a wireless connection. The method also includes determining an virtual local area network corresponding to the determined service set identifier. The virtual local area network is located in an extended service set. The extended service set includes a group of basic service sets. The method further includes identifying one or more access points located in the virtual local area network. The method further includes configuring the identified one or more access points to match a plurality of service parameters of the selected access point.

Claims

1. A method for synchronizing access points in a wireless network, comprising:

discovering, by a managing device, a plurality of access points in a wireless network;

selecting, by the managing device, an access point from the plurality of discovered access points to be a selected access point;

determining, by the managing device, a service set identifier of the selected access point in the wireless network, the service set identifier identifying a name of a wireless connection, the selected access point having a first plurality of service parameters, wherein the first plurality of service parameters comprises a plurality of parameters, wherein at least one parameter is selected from the group consisting of;

an authentication parameter, an encryption parameter, and a network routing parameter;

determining, by the managing device, a virtual local area network (VLAN) corresponding to the determined service set identifier of the selected access point, the VLAN located in an extended service set, the extended service set comprising a plurality of basic service sets;

identifying, by the managing device, one or more access points other than the selected access point located in the determined VLAN, the one or more identified access points in the determined VLAN each having a respective second plurality of service parameters;

configuring, by the managing device, each second plurality of service parameters of the one or more access points other than the selected access point to match the first plurality of service parameters of the selected access point; and

providing seamless roaming of an endpoint device using the matched first plurality of service parameters.

2. The method of claim 1, wherein determining, by the managing device, the service set identifier of the selected access point comprises determining, by the managing device, a service set identifier of the selected access point corresponding to a native VLAN.

3. The method of claim 1, wherein determining, by the managing device, the service set identifier of the selected access point comprises determining, by the managing device, a service set identifier of a selected access point corresponding to an infrastructure service set identifier.

4. The method of claim 1, wherein determining, by the managing device, the service set identifier of the selected access point comprises determining, by the managing device, a service set identifier of a selected access point corresponding to a broadcast service set identifier.

5. The method of claim 1, wherein determining, by the managing device, the service set identifier of the selected access point comprises determining, by the managing device, a service set identifier of a selected access point corresponding to a most recently added service set identifier.

6. The method of claim 1, wherein the first plurality of service parameters comprises an authentication parameter.

7. The method of claim 1, wherein the first plurality of service parameters comprises an encryption parameter.

8. The method of claim 1, wherein the first plurality of service parameters comprises a network routing parameter.

9. A system for synchronizing access points in a wireless network, comprising:

a plurality of access points in the wireless network; and

a managing device operable to connect to the wireless network, the managing device comprising;

a processor; and

a storage device embodying a program of instructions operable, when executed on the processor, to;

select an access point from the plurality of access points to be a selected access point;

determine a service set identifier of the selected access point in the wireless network, the service set identifier identifying a name of a wireless connection, the selected access point having a first plurality of service parameters, wherein the first plurality of service parameters comprises a plurality of parameters, wherein at least one parameter is selected from the group consisting of;

an authentication parameter, an encryption parameter, and a network routing parameter;

determine a virtual local area network (VLAN) corresponding to the determined service set identifier of the selected access point, the VLAN located in an extended service set, the extended service set comprising a plurality of basic service sets;

identify one or more access points other than the selected access point located in the determined VLAN, the one or more identified access points in the determined VLAN each having a respective second plurality of service parameters;

configure each second plurality of service parameters of the one or more access points other than the selected access point to match the first plurality of service parameters of the selected access point; and

provide seamless roaming of an endpoint device using the matched first plurality of service parameters;

wherein the first and second plurality of service parameters are operable to differentiate access to the wireless network for security purposes.

10. The system of claim 9, wherein the program is further operable to determine the service set identifier of the selected access point by determining a service set identifier of the selected access point corresponding to a native VLAN.

11. The system of claim 9, wherein the program is further operable to determine the service set identifier of the selected access point by determining a service set identifier of a selected access point corresponding to an infrastructure service set identifier.

13. The system of claim 9, wherein the program is further operable to determine the service set identifier of the selected access point by determining a service set identifier of a selected access point corresponding to a most recently added service set identifier.

14. The system of claim 9, wherein first plurality of service parameters comprises an encryption parameter.

15. The system of claim 9, wherein the first plurality of service parameters comprises an authentication parameter.

16. A non-transitory computer-readable medium encoded with logic, the logic being operable, when executed on a processor, to:

discover a plurality of access points in a wireless network;

select an access point from the plurality of discovered access points to be a selected access point;

determine a service set identifier of the selected access point in the wireless network, the service set identifier identifying a name of a wireless connection, the selected access point having a first plurality of service parameters, wherein the first plurality of service parameters comprises a plurality of parameters, wherein at least one parameter is selected from the group consisting of;

an authentication parameter, an encryption parameter, and a network routing parameter;

determine a virtual local area network (VLAN) corresponding to the determined service set identifier of the selected access point, the VLAN located in an extended service set, the extended service set comprising a plurality of basic service sets;

identify one or more access points other than the selected access point located in the determined VLAN, the one or more identified access points in the determined VLAN each having a respective second plurality of service parameters;
