Patent ID: 8089874

Claim:
A method comprising: sensing an error in a network topology based on a network transmission failure; in response to identifying the error, flooding accessible mesh network routes from a first node to a destination node with transmissions of explore frames originating at the first node, wherein each transmitted explore frame collects node identifiers of each intermediate node that is traveled en route to the destination node, and to instruct the destination node to transmit a report frame back to the first node once each transmitted explore frame reaches the destination node; receiving the report frame at the first node from the destination node, wherein the report frame includes all node identifiers associated with the transmission of the explore frame from the first node to the destination node; determining at least one functional network route from the first node to the destination node based at least in part on the node identifiers received in association the report frame, wherein the node identifiers indicate a functional node path from the first node to the destination node; and transmitting an instruction to the destination node from the first node based on the functional node path.
