System and method for rate agile adaptive clocking in a packet-based network

摘要

A system for transmitting a clock signal through a packet-based network is disclosed. The system comprises a first node configured to measure a clock frequency of the clock signal and calculate an accuracy indicator of the measured clock frequency; a second node configured to receive the clock frequency measurement and the accuracy indicator of the clock frequency measurement, and synthesize the clock signal therefrom; and a packet-based network for transmitting the measured clock frequency and accuracy indicator from the first node to the second node. A method of deriving a clock frequency by identifying packets with the shortest total transmission time is also disclosed.
