ABSTRACT:
Remote frequency synchronization is achieved between two or more nodes in a packet-switched network using differential timestamps. A line is fit to multiple differential time values using a minimum delay principle. Frequency synchronization and/or absolute time synchronization between the two nodes may be achieved using one or both of uplink and downlink differential time values and fitting one or both of first and second lines to differential time values by different means of the minimum delay principle.
