Abstract

An authentication method in a mesh AP including using standard IEEE 802. 11i mechanisms between the mesh AP and an authenticator for authenticating the mesh AP to become a child mesh AP with a secure layer-2 link to a first parent mesh AP that has a secure tunnel to a Controller, including, after a layer-2 link between the child mesh AP and the first parent mesh AP is secured, undergoing a join exchange to form a secure tunnel between the child mesh AP and the Controller Further, a fast roaming method for re-establishing a secure layer-2 link with a new parent mesh AP including, while the mesh AP is a child mesh AP to the first parent mesh AP and has a secure layer-2 link to the first parent mesh AP, caching key information and wireless mesh network identity information.
