PROACTIVE CREDENTIAL CACHING
First Claim
1. A method comprising:
- publishing at least a portion of a first credential as a global credential for use by access nodes to use in admitting a station to a wireless network;
publishing at least a portion of a second credential as a global credential for use by the access nodes in admitting the station to the wireless network;
receiving a request from the station for admission to the wireless network using the first credential;
automatically republishing at least a portion of the first credential as the global credential for use by the access nodes in admitting the station to the wireless network.

Abstract
In wireless networking, such as per the IEEE 802.11 standard, a technique automatically republishes an authentication credential to a global credential repository. A station can have a first credential, as is created when the station connects to a first access node of a wireless network. Upon trying and failing to connect to a second access node of the wireless network, the station can have a second credential created and published to the global credential repository. In some situations, the station then roams back to the first access node using the first credential. Efficiently, when the station uses the first credential at the first access node, the first credential can be automatically republished as a global credential. The automatic republishing of the first credential can ensure that the station is able to access the wireless network via various access nodes when roaming.

8. A system comprising:
-
a first access node associated with a wireless network and a global credential repository; and a second access node associated with the wireless network and the global credential repository; wherein, in operation, the first access node associates a station using a first credential, publishes at least a portion of the first credential to the global credential repository, and uses the first credential to send and receive data with the station; the second access node attempts and fails to associate the station using the first credential, associates the station using a second credential, and publishes the second credential to the credential cache; the first access node receives a request from the station to associate using the first credential, associates the station using the first credential and automatically re-publishes the first credential to the cache; wherein the first access node and the second access node use the first credential to associate the station associates with the wireless network. - View Dependent Claims (9, 10, 11, 12, 13)

14. A method comprising:
-
transmitting a request to a credential creator in response to a request for a credential from a station received at a first authenticator; receiving a first credential from the credential creator authorizing the station to transmit and receive data with a plurality of authenticators; publishing at least a portion of the first credential as a global credential shared with the plurality of authenticators; receiving a request at a second authenticator from the station for an authentication credential; requesting and receiving a second authentication credential for the station from the credential creator; publishing at least a portion of the second authentication credential as the global credential; receiving a request from the station to associate at the first authenticator using the first authentication credential; automatically republishing at least a portion of the first authentication credential as the global credential. - View Dependent Claims (15, 16, 17, 18, 19, 20)
