Algorithms following the peer-to-peer Precision Time Protocol (PTP) specified by the IEEE 1588 standard achieve synchronization of distributed clocks by propagating the timing information of a preselected master clock throughout the entire network. Based on this noisy timing information, each slave clock tries to follow as closely as possible the master time. In this work we formulate clock synchronization as a stochastic estimation-control problem. A two dimensional LQG controller is derived… CONTINUE READING
