Classification: CPC H | IPC H

Claim 4:
5. The network of claim 1, wherein:
the ingress node comprises an ingress clock configured to generate an ingress timestamp for each TDM packet transmitted by the ingress node in the TDM flow;
the egress node comprises an egress clock configured to generate an egress time for each TDM packet received by the egress node in the TDM flow;
for each TDM packet, the egress node is configured to generate a time difference between the ingress timestamp and the egress time for the TDM packet;
for each subset of TDM packets, the egress node is configured to generate an average time difference between the ingress timestamps and the corresponding egress times; and
the egress node is configured (i) to track evolution of the average time differences to characterize a timing difference between the ingress clock and the egress clock and (ii) use the characterized timing difference in generating the one or more outgoing flows.
