Claim:
1. A transmission device, comprising: first circuitry configured to update timestamp fields contained in timing-related messages contained in at least some packets received by the first circuitry utilizing at least predicted delays, wherein updating the timestamp field comprises determining the predicted delay and writing information regarding the predicted delay into the timestamp field; second circuitry configured to process the packet according to a packet protocol and adapt the at least some packets, received from said first circuitry and comprising said updated timestamp fields, from the packet protocol to a synchronous protocol, the second circuitry coupled to the first circuitry, the second circuitry further configured to transmit a signal formatted according to the synchronous protocol containing the at least some packets, the second circuitry comprising a buffer configured to match data rates between the packet protocol and the synchronous protocol; and third circuitry configured to predict the delays that will be incurred by the at least some packets in the second circuitry, based on delay related information from the second circuitry, said delay related information responsive to the present state of the second circuitry, the present state of the second circuitry comprising a status of the second circuitry buffer, and supply the predicted delays to the first circuitry configured to update timestamp fields, wherein said delay prediction comprises determining a delay that will be incurred in processing the packet according to the packet protocol and determining a delay that will be incurred in adapting the packet for transmission using the synchronous protocol.
