Patent ID: 8199695

Claim:
A method of clock signal synchronization among computers in a network, the method comprising: designating, as a primary clock signal for all the computers in the network, a clock signal from one of the computers in the network, each computer in the network comprising a clock signal generator having as an output a clock signal capable of coordinating operations among the computers in the network and also capable of interconnection to each of the other computers through a multiplexer in each computer and a narrow-bandwidth phase locked loop in each computer; providing the primary clock signal, simultaneously and in parallel, from the computer whose clock signal is designated as the primary clock signal to all the other computers in the network; and providing the primary clock signal, simultaneously and in parallel, from each computer in the network to all computers in the network through the multiplexers and the phase locked loops, with the primary clock signal locked in phase across all the computers by the phase locked loop on each computer.
