Abstract
A method of routing synchronization messages in a packet communication network, in which a packet is routed using a global routing table. A piece of equipment in the network implements the following steps: detecting a packet carrying a synchronization message in a packet stream; determining an output port; emitting a packet carrying the message at the determined output port, the message being modified using a piece of information representing a time of transit in the equipment. A synchronization routing table, which stores at least one association between an input port and at least one output port, is configured in the equipment. When the packet carrying the received message indicates a routing needs to be carried out using the synchronization table, the output port for this packet is determined by the equipment according to an input port on which the packet is received and by reading the synchronization table.
