Claim Text:
1. A method for synchronizing master and slave clocks of a packet-switched network, said master and slave clocks exchanging synchronization packet flows with one another via intermediary equipments of that network that are connected to one another, said method comprising the following steps: i) determining within each intermediary equipment instant transit times of packets belonging to a first group of packets of at least one chosen flow of synchronization packets, determining a maximum transit time of the packets based on said instant transit times, then acting on packets of a second group of said chosen flow so that said instant transit times within each intermediary equipment is within 10 microseconds of said corresponding maximum transit time, and ii) filtering the packets of said chosen flow at least within said slave clock in order to synchronize it to said master clock by means of the processed packets of said second group of that chosen flow.
