Abstract:
1. A method comprising: detecting a neighboring wireless network access point; determining if the neighboring wireless network access point is connected in a first network subnet different than a current network subnet; providing tunneling information to the neighboring wireless network access point in response to the determination that the neighboring wireless network access point is connected in the first network subnet, wherein the tunneling information establishes a connection between a first network device in the first network subnet and a second network device in the current network subnet; connecting with a first wireless client via a first network connection; determining predictive roaming information that identifies the first wireless client; providing the predictive roaming information to the neighboring wireless network access point while connected with the first wireless clients receiving a query message that identifies a home network subnet associated with the first wireless client sent in response to the determination that the identifying information does not match at least a portion of the predictive roaming information; sending a response to the query message including additional tunneling information that establishes a network connection between a third network device in the home network subnet and the second network device in the current network subnet; establishing a second network connection from the first wireless client to the third network device in the home network subnet via the second network device in the current network subnet, wherein all network traffic associated with the first wireless client passes through the third network device in the home network subnet via the second network connection.
