<P>PROBLEM TO BE SOLVED: To provide a method and system for correcting inaccurate time synchronization caused by internal asymmetric delays in a device with a local clock. <P>SOLUTION: A method for time synchronization that avoids inaccurate time synchronization caused by asymmetric delays in the device 300 is disclosed. Time synchronization according to the present teachings includes determining an asymmetry between an internal delay of an inbound timing packet in the device 300 and an internal delay of an outbound timing packet in the device 300 and correcting a time synchronization in response to the asymmetry. <P>COPYRIGHT: (C)2007,JPO&INPIT |
