摘要： There is provided a GNSS independent method for asymmetry delay error compensation to minimize a time difference bias when using two-way time transfer in a communication network. The method includes establishing a bidirectional virtual path comprising at least one link path, LP1-LP4, over the network for communication between a first node A and a second node B by sending a bidirectional data stream over the virtual path and utilizing previously stored link profiles associated with a delay correction factor or a calibrated virtual path or a stable local clock in holdover mode to provide new delay correction factor to minimize a time difference bias in the local time in the second node.

摘要： There is provided a method in a communication network system 100 of e.g. IP type for live distribution of media content capable of node-to-node time-transfer between nodes in the network system. The media content is sent as a data stream DSx via respective communication links over a network 200. The method comprises transferring local clock signal between nodes and based on received local clock signals determining a unidirectional delay between the nodes. The traffic between the nodes is then based on the determined unidirectional delay.

摘要： An apparatus for switching data between a first set of bitstreams and a second set of bitstreams, each of said bitstreams being divided into recurring frames and each of said recurring frames being divided into time slots, is disclosed. The switch comprises a first set of switching elements, at least one intermediate set of switching elements, and a last set of switching elements. Each switching element comprises a number of input ports and a number of output ports. The input ports of the first set of switching elements are arranged to receive the first set of bitstreams and the output ports of the last set of switching elements are arranged to provide said second set of bitstreams. Furthermore the switching elements are arranged so that there are more than one path from a switching element in the first stage to a switching element in the last stage. Each switching element is arranged so that it provides for both time and space switching of data from incoming bitstreams, referring to the input ports of the switching element, to outgoing bitstreams, referring to the output ports of the switching element.

摘要： The present invention relates to methods for changing the bandwidth of a circuit switched channel in a time division multiplexed network, wherein said channel comprises a set of time slots within each recurring frame of a bitstream between a first node and a second node. According to the invention one or more additional time slots within each recurring frame of said bitstream are reserved, including using, during a period of time, only said set of time slots for transmitting payload data pertaining to said channel while providing, during said period of time, information indicating that said one or more additional time slots are currently not used for transferring payload data. After said period of time, said set of time slots is used as well as said one or more additional time slots on said bitstream for transmitting payload data pertaining to said channel.
