Abstract
A method for synchronizing a plurality of servers of a communication network, which are capable of exchanging time-stamped data using a time reference. The method is implemented by a primary server of the plurality and includes: transmitting to the other servers, called secondary servers, an initialization message containing an identifier of the primary server, a data item resulting from execution of an algorithm for selecting the primary server from the plurality of servers, and a piece of transmission time information on the initialization message; receiving from at least one secondary server a message acknowledging the transmitted initialization message; and validating a synchronization challenge comprising a difference between a recorded transmission time reference and the piece of transmission time information on the initialization message. The piece of transmission time information replaces the recorded time reference for the time-stamping of the data exchanged between the servers once the validation is complete.
