Abstract:
A node in a mesh network includes insertion circuitry to selectively delay first packets prior to insertion in a mesh network by a first time interval corresponding to a maximum failure detection time interval for the mesh network based on whether a failure has been detected in the mesh network. The node includes reception circuitry configured to selectively delay second packets received from the mesh network by a second time interval depending on whether the failure has been detected. The second time interval equals a maximum latency for the mesh network minus a sum of the maximum failure detection time interval and a propagation time along a working path. If a failure is detected, the second packets are delayed by a third time interval determined based on the maximum latency, the maximum failure detection time interval, and a propagation time along a backup path for the working path.
