In a communication network, a method for synchronizing delivery clocked by the high precision time protocol

摘要

The method, - from the first peer-to-peer transparent clock (P2P TC B), transmitting a Sync message (SYNC) to a second peer to peer transmission clock (P2P TC C), - the synchronization message is transmitted from a first peer to peer transmission clock is moved to a second peer to peer transmission clock and a then, in order to update the time information carried by the synchronization message, and a step to consider this path delay - estimating the path delay of the path,In order to estimate the the path delay, the method: - to create a list of the network address of the network interface that is traversed by the synchronization message (SYNC) (IPRB, IPRI1, IPRI2, IPRC) a step, - the order in which the network interface is traversed by the Sync message (SYNC), comprising the steps of ordering the first list, - by reversing the order of the first list a step of creating a second list, - a step of transmitting the second list in the second peer-to-peer transmission clock (P2P TC C), - each Pdelay_Req messages and Pdelay_Resp Message by limiting the path, in order to allow each path is mapped into the ordered list and the ordered list of second interface which is traversed in the first, available in the transport protocol level I and a step of using the mechanism.
