Abstract
Aspects of the present disclosure includes a method and program product for clock synchronization of a networked computer system. The method records a time (t) when a first codeword marker in a datastream is sent from a master computer to a slave computer and records a second time (t) when the slave computer receives the first codeword marker. The method includes recording a third time (t) when a third codeword marker in a datastream is sent from the slave computer to the master computer. The method includes recording a fourth time twhen the master receives the third codeword marker from the slave. The method calculates a time offset θ, according to; and a roundtrip delay δ, according to δ=(t−t)−(t−t). The clock in the slave computer is synchronized with a clock in the master computer using θ and δ.
