Abstract:
1. A method, comprising: determining a trigger for establishing transmission priority on a path through a shared-media communication network for priority traffic to a particular node, wherein the trigger is determined to have occurred when a particular type of data flow has been received at a root node; in response to determining that the trigger has occurred at the root node, generating a path clear message (PCM); transmitting the PCM along the path to the particular node to establish the transmission priority for the priority traffic along the path through the shared-media network; suspending transmission for traffic other than the priority traffic for a specified duration; transmitting the priority traffic to the particular node along the path during the transmission priority; and transmitting a transmission priority clearing message along the path in response to completion of the transmission priority; and resuming transmission for other traffic after the specific duration.
