Abstract
A network component comprising a source-delay locked loop (S-DLL), a source timestamp queue (S-Q) coupled to the S-DLL, and a switch fabric coupled to the S-Q such that the S-Q is positioned between the switch fabric and the S-DLL, and wherein the S-DLL is configured to couple to an absolute timing component. Disclosed is a method comprising queuing a plurality of timestamps at a plurality of timestamp intervals from a source node, returning the received timestamps to the source node at the same timestamp intervals, receiving a plurality of offsets corresponding to the timestamps that are calculated using a virtual delay time for the timestamps from the source node, and aligning the queued timestamps to match the virtual delay time before processing additional timestamps to synchronize transmissions and establish frequency alignment with the source node.
