Abstract

See full text

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 a time stamp generated by a source node in the time stamp field. The network device determines that the packet conforms to the protocol. The network device adds to the packet a new general purpose extension field. The new general purpose extension field specifies time correction information indicating a residence time of the packet in the network device, where the time correction information is for correcting the time specified by the time stamp.
