Title: METHOD AND SYSTEM FOR TRANSMIT TIME STAMP INSERTION IN A HARDWARE TIME STAMP SYSTEM FOR PACKETIZED DATA NETWORKS
Abstract:
A system (100) for time-stamping a data packet associated with a data network includes a network media interface device (102) for transferring a data packet to a network medium (104), a time-stamping circuit (110) for sampling the time code from the time source when the data packet is available to be transferred to the network medium (104) so as to acquire an outgoing time code. The time-stamping circuit (110) also embeds the outgoing time code into a predetermined field in the data packet, provides the data packetto the media interface device (102) for transfer to the network medium (104).
