Abstract
A first node provides a time function to a second node. The first node generates a time function protocol data unit required for supporting the time function and generates a plurality of preamble protocol data units. The plurality of preamble protocol data units are sent before the time function protocol data unit. The preamble protocol data units carry routing information to cause the preamble protocol data units to follow a same network path as the time function protocol data unit. At an intermediate node the plurality of preamble protocol data units, the time function protocol data unit and other data traffic are stored in queues of different priority level. The intermediate node controls a time order of forwarding based on priority levels of the queues.
