WIRELESS MESH NETWORK INCLUDING RESILIENT BACKHAUL LINKS AND WLAN TRAFFIC LOCAL SWITCHING
First Claim
1. A method comprising:
- at a mesh access point (MAP) in a wireless mesh network including access points (APs) of a spanning tree being divided among multiple Internet Protocol (IP) subnets, each IP subnet associated with a corresponding IP subnet identifier;
receiving from a first parent AP to which the MAP is a child a first IP subnet identifier indicating the first IP subnet to which the first parent AP belongs;
obtaining a first IP address associated with the first IP subnet;
roaming from the first parent AP to a second parent AP;
receiving from the second parent AP a second IP subnet identifier indicating a second IP subnet to which the second parent AP belongs;
determining if the first parent AP and the second parent AP are both part of the same IP subnet; and
determining whether to maintain connectivity with a current controller of the mesh network or establish connectivity to a new controller of the mesh network based on results of the determining.

Abstract
A method is performed at a mesh access point (MAP) in a wireless mesh network including access points (APs) of a spanning tree being divided among multiple Internet Protocol (IP) subnets. The method includes receiving from a first parent AP to which the MAP is a child a first IP subnet identifier indicating the first IP subnet to which the first parent AP belongs. The method also includes obtaining a first IP address associated with the first IP subnet, roaming from the first to a second parent AP, receiving from the second parent AP a second IP subnet identifier indicating a second IP subnet to which the second parent AP belongs, determining if the first and second parent APs are both part of the same IP subnet, and determining whether to maintain connectivity with a current controller or establish connectivity to a new controller based on results of the determining.

10. An apparatus comprising:
-
one or more radios in a mesh access point (AP) of a wireless mesh network including access points (APs) of a spanning tree being divided among multiple Internet Protocol (IP) subnets, each IP subnet associated with a corresponding IP subnet identifier; a memory; and a processor coupled to the one or more radios and the memory, the processor configured to; receive from a first parent AP to which the MAP is a child a first IP subnet identifier indicating the first IP subnet to which the first parent AP belongs; obtain a first IP address associated with the first IP subnet; roam from the first parent AP to a second parent AP; receive from the second parent AP a second IP subnet identifier indicating a second IP subnet to which the second parent AP belongs; determine if the first parent AP and the second parent AP are both part of the same IP subnet; and determine whether to maintain connectivity with a current controller of the mesh network or establish connectivity to a new controller of the mesh network based on results of the determining. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A tangible processor readable medium storing instructions that, when executed by a processor, cause the processor to, at a mesh access point (MAP) in a wireless mesh network including access points (APs) of a spanning tree being divided among multiple Internet Protocol (IP) subnets, each IP subnet associated with a corresponding IP subnet identifier:
-
provide receive from a first parent AP to which the MAP is a child a first IP subnet identifier indicating the first IP subnet to which the first parent AP belongs; obtain a first IP address associated with the first IP subnet; roam from the first parent AP to a second parent AP; receive from the second parent AP a second IP subnet identifier indicating a second IP subnet to which the second parent AP belongs; determine if the first parent AP and the second parent AP are both part of the same IP subnet; and determine whether to maintain connectivity with a current controller of the mesh network or establish connectivity to a new controller of the mesh network based on results of the determining. - View Dependent Claims (18, 19, 20)
