TRANSMISSION PRIORITY PATHS IN MESH NETWORKS
First Claim
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;
generating a path clear message (PCM), the PCM to instruct one or more receiving nodes along the path to suspend transmission for traffic other than the priority traffic for a specified duration, and also to transmit a local non-repeated distributed message to one or more neighbor nodes of each respective receiving node, the local non-repeated distributed message to instruct the neighbor nodes to suspend transmission for the specified duration;
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; and
transmitting the priority traffic to the particular node along the path during the transmission priority.

Abstract
In one embodiment, a node may determine a trigger for establishing transmission priority on a path through a shared-media communication network for priority traffic to a particular node. As such, the node may generate a path clear message (PCM) that would instruct one or more receiving nodes along the path to suspend transmission for traffic other than the priority traffic for a specified duration, and also to transmit a local non-repeated distributed message to one or more neighbor nodes of each respective receiving node, the local non-repeated distributed message to instruct the neighbor nodes to suspend transmission for the specified duration. After 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, the priority traffic may be transmitted to the particular node along the path during the transmission priority.

14. A method, comprising:
-
receiving a path clear message (PCM) at a receiving node along a path to a particular node in a shared-media communication network, the PCM to instruct the receiving node to suspend transmission for traffic other than the priority traffic for a specified duration, and also to transmit a local non-repeated distributed message to one or more neighbor nodes of the receiving node, the local non-repeated distributed message to instruct the neighbor nodes to suspend transmission for the specified duration; in response to the PCM;
suspending transmission for traffic other than the priority traffic for the specified duration, and transmitting the local non-repeated distributed message to one or more neighbor nodes of the receiving node, the local non-repeated distributed message to instruct the neighbor nodes to suspend transmission for the specified duration;receiving the priority traffic to the particular node during the transmission priority; and transmitting the priority traffic toward the particular node along the path during the transmission priority. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22)

23. An apparatus, comprising:
-
one or more network interfaces to communicate in a shared-media computer network; a processor coupled to the network interfaces and adapted to execute one or more processes; and a memory configured to store a process executable by the processor, the process when executed operable to; receive a path clear message (PCM) at the apparatus as a receiving node along a path to a particular node in a shared-media communication network, the PCM to instruct the receiving node to suspend transmission for traffic other than the priority traffic for a specified duration, and also to transmit a local non-repeated distributed message to one or more neighbor nodes of the receiving node, the local non-repeated distributed message to instruct the neighbor nodes to suspend transmission for the specified duration; in response to the PCM;
suspend transmission for traffic other than the priority traffic for the specified duration, and transmit the local non-repeated distributed message to one or more neighbor nodes of the receiving node, the local non-repeated distributed message to instruct the neighbor nodes to suspend transmission for the specified duration;receive the priority traffic to the particular node during the transmission priority; and transmit the priority traffic toward the particular node along the path during the transmission priority.
