System and method for high precision clock recovery over packet networks

A system for high precision clock recovery over a packet switched network, said system comprising:

• means for generating packets at a local unit carrying information to a remote unit using a local clock signal, wherein each generated packet carries a transmitted timestamp;
• means for generating a remote timestamp at said remote unit for each said generated packet;
• means for obtaining minimum network delay estimation for filtering out network jitter, wherein said minimum network delay estimation is defined as a time delay in which a packet remains in the packet switched network, assuming that all transmission queues through which said packet passes are empty;
• and
• reconstructing a received clock signal based on a time difference between said transmitted timestamp and said remote timestamp.
