Claim 16:
17. A method comprising:
receiving a first local time information from a first network element;
receiving a second local time information from a second network element;
at a control system, computing, from the first local time information and the second local time information, one or more global time values;
transmitting the one or more global time values to the first network element or to a third network element different from the first and second network elements;
computing at least one of a sum or a difference of the received first local time information and the received second local time information;
determining a difference between a first propagation delay and a second propagation delay based on the at least one of a sum or a difference of the received first local time information and the received second local time information;
wherein the first propagation delay represents a propagation delay between an optical power supply and the first network element, and the second propagation delay represents a propagation delay between the optical power supply and the second network element.
