Abstract:
1. A method for communicating over a network comprising the steps of: at an ingress node of said network, accepting a client signal arriving synchronized to a client-signal clock; synchronizing said client signal to a processing clock of said ingress node while forming framing layer frames into which said client signal is inserted; developing measures of phase-offset between said client signal clock and said processing clock of said ingress node; developing an output signal of said ingress node comprising said framing layer frames and said measures; communicating said output signal to an egress node of said network; at said egress node, extracting said client signal from framing layer frames of said egress node; developing a client clock from said extracted client data and from phase-offset measure obtained from said framing layer frames of said egress node; and outputting said extracted client data with the developed client clock; wherein each of said ingress nodes and said egress node comprise:
