Abstract
The method includes sending a Sync message from a first peer-to-peer transparent clock to a second peer-to-peer transparent clock, estimating the path delay of the transmission path traveled by the synchronization message from the first to the second peer-to-peer transparent clocks, and taking this path delay into account for updating the time information carried by a synchronization message. The estimating includes creating a list of the network addresses of the network interfaces traversed by the synchronization message; ordering the first list into the order in which the network interfaces have been traversed by the Sync message; creating a second list by reversing the order of the first list; communicating the second list to the second peer-to-peer transparent clock; and using the mechanism available at the transport protocol level, to constrain the respective paths of Pdelay_Req and Pdelay_Resp messages so that their respective paths map to the second and first ordered lists of traversed interfaces.
