Providing a backup network topology without service disruption

摘要

In one embodiment, a primary root node may detect one or more neighboring root nodes based on information received from a first-hop node and may select a backup root node among the neighboring root nodes. Once selected, the backup root node may send the primary root node a networking identification and a corresponding group mesh key which the primary root node may forward to the first-hop nodes to cause the first-hop nodes to migrate to the backup root node when connectivity to the primary root node fails. In addition, the first-hop root nodes may migrate back to the primary root node when connectivity to the primary root node is restored.

1. A method, comprising:
detecting, by a primary root node, one or more neighboring root nodes based on information received from first-hop nodes in a shared-media communication network; selecting a backup root node from the neighboring root nodes; receiving a network identification and a corresponding mesh group key from the backup root node; and notifying the first-hop nodes of the backup root node along with the network identification and the corresponding mesh group key to cause the first-hop nodes to migrate to the backup root node when connectivity to the primary root node fails, while maintaining a subordinate state.
