摘要： The invention is directed to a clock module and method for distributing a time reference to at least one clock in a packet-switched network. The clock module includes a slave port, a master port and a local clock. The method comprises the steps of receiving a first synchronization packet at the slave port, the first synchronization packet comprising a first master clock timestamp and generating at least one internal signal comprising the first master clock timestamp. The method also includes the steps of transmitting the at least one internal signal to the master port and receiving the at least one internal signal at the master port. Then a method includes determining the internal propagation time of the signal through the clock module and generating a second synchronization packet at the master port comprising a second master clock timestamp, the second master clock timestamp comprising the sum of the first master clock timestamp and the internal propagation time. Finally, the second synchronization packet is sent to at least one other clock in the packet-switched network.

摘要： A network element for a packet-switched network has a plurality of network ports for exchanging synchronization messages with further network elements, a local clock, a timestamp generation module associated to each network port for triggering generation of a timestamp, and a synchronization control module selectively configurable in a first operating mode and a second operating mode as a function of a configuration signal. When the synchronization control module is configured in the first operating mode, it is adapted to adjust an offset of the local clock as a function of the timestamps of the synchronization messages received through the slave port. When the synchronization control module is configured in the second operating mode, it is adapted to compute a residence time of a synchronization message in the network element as a function of the timestamps obtained at the time of receiving and sending the synchronization message.

摘要： 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.

摘要： The method for detecting and managing a synchronization failure of a transparent clock is used in a packet network in order to determine and correct residence time of time-stamped packets within a traversed element of said network. The transparent clock is part of a Master/Slave synchronization path including a plurality of network elements and their associated transparent clocks. The method includes transmitting time-stamped packets from the Master to the Slave through different synchronization paths in order to have the Slave receiving multiple time signals transmitted through different paths, and determining a failure within a transparent clock of a failed/failing synchronization path if the time signal provided by said failed/failing path differs from the time signal provided by the other transmitting path(s).

摘要： An exemplary technique is provided for synchronizing master and slave clocks of a packet-switched network. The network contains at least two equipments that are connected to one another via an aggregated connection made up of at least two links and that are located between the master and slave clocks to enable them to transmit synchronization packets to one another using a timestamp protocol. The technique includes (a) obtaining a distribution of the synchronization packets in at least one subset of the links that transport these synchronization packets, and (b) transmitting to the slave clock first information representative of that distribution, second information representative of timestamps associated with the synchronization packets, and third information representative of packet transmission times over the at least one subset of links, to synchronize the slave clock to the master clock as a function of at least the first, second, and third information transmitted.

摘要： A method for measuring the resident time of a probe message in at least a network node within a network path, includes registering the receive timestamp of the probe message, writing the receive timestamp into a dedicated field within the received probe message, and checking the Time-To-Live value of the probe message. If the Time-To-Live value is not null, the Time-To-Live value is decremented by one. If the Time-To-Live value is equal to one, then the method includes registering the transmit timestamp of the probe message, computing the probe message resident time within the network node by subtracting the registered receive timestamp from the registered transmit timestamp, writting the computed resident time into a field within the probe message, and changing the value of a flag within the received probe message in order to protect the resident time from being over written by subsequent action on the probe message.
