Abstract
A method and system for synchronizing a server cluster having a plurality of nodes each provided with an internal clock and interconnected with each other by a clock interconnection network comprising a plurality of transmission segments. Time-stamping information is generated by the internal clock of a source chosen from the nodes of the server cluster. The time-stamping information is transmitted to all the nodes in the server cluster from the source; and and the internal clock of each node of the server cluster is adjusted from this time-stamping information The time for transmission of the time-stamping information is adjusted by each transmission segment to a constant value established for each transmission segment. Upon receiving the time-stamping information by any one of the nodes in the server cluster, its internal clock is adjusted from the time-stamping information and information relating to the transmission segments passed through between the source and this node.
