METHOD FOR TRANSMITTING IEEE 1588V2 TYPE SYNCHRONIZATION PACKETS ON ETHERNET IN LINK LINK MODE, THROUGH NETWORK EQUIPMENT HAVING A TRANSPARENT CLOCK, AND ASSOCIATED DEVICE

摘要

A method is dedicated to the transmission of synchronization packets between master (HM) and slave (HE) clocks of a packet-switched network supporting an Ethernet protocol at their interfaces, each associated with a measurement module (MM). ) serving as a support for an IEEE 1588V2 time stamping protocol, and connected to each other via a network path defined by a routing or label switching protocol, in order to transmit synchronization packets on the network. This method comprises the following steps: i) insert in a synchronization packet to be transmitted from one of the master (HM) and slave (HE) clocks, then said source, to the other master clock (HM) or slave ( HE), then called destination, information representative of at least a part of the network path defined with respect to the routing protocol or label switching, and ii) encapsulate on Ethernet the synchronization packet that has been the object of an insert, then transmit this encapsulated packet in a link-by-link mode to the destination clock.
