Abstract
A network device receives a packet that conforms to a protocol that i) defines a time stamp field, ii) does not define a dedicated field for time correction information, and iii) defines a plurality of general purpose extension fields. The packet includes (i) a time stamp generated by a source node in the time stamp field, and (ii) a time correction value corresponding to multiple ones of the plurality of intermediate nodes, the time correction value being located in one of the general purpose extension fields. The network device identifies (i) a time specified by the time stamp, and (ii) time correction information specified in the one general purpose extension field, and uses the time correction information and the time specified by the time stamp to synchronize a clock maintained by the network device to a clock maintained by the source node.
