Abstract
A method of routing data in a mesh communication network including a plurality of network devices and operating in a process control environment, including assigning one of a plurality of priority levels associated with the communication network to a data packet, sending the data packet from a source network device included in the plurality of network devices to a destination network device included in the plurality of network devices, and routing the data packet to a destination network device via at least one intermediate network device included in the plurality of network devices. The act of routing includes comparing, at each intermediate network device, the priority level of the data packet to a priority mask of the intermediate network device, and modifying at least one of scheduling or routing of the data packet if the priority level of the data packet is not associated with the priority mask of the intermediate network device.
