Abstract:
1. A method for a device to implement one of the nodes in a wireless network for processing packets, comprising: submitting a request to a network-management system in the network to become a node in the network; after having registered with the network-management system, determining neighboring nodes; sending a link-state advertisement to the network-management system, the link-state advertisement providing neighboring relationships of the node; processing the packets using switching rules for a tree switching network portion of the network, the switching rules defining at least one of (1) an ingress link to a parent node with a power capability greater than the node and (2) egress links to child nodes with a mobility greater than the node, wherein the network-management system is not a part of the tree switching network portion; determining if a wireless link to a neighboring node has failed; and when a wireless link to a neighboring node has failed, informing a node at the end of an ingress wireless link and the network-management system of the failed link.
