  • Publication number: 20160329979
    Abstract: A method for indicating one-way latency in a data network, with continuous clock synchronization, between first and second node having clocks that are not synchronized with each other includes a continuous synchronisation session and a measurement session. The method repetitively sends predetermined synchronization messages from the first node to the second node and from the second node to the first node, calculates a round trip time for each message at the first node, updates a synchronization point if the calculated round trip time is smaller than a previously calculated round trip time, stores the updated synchronization points of a synchronization window, and calculates a virtual clock from the updated synchronization points of the synchronization window. The measurement session collects multiple measurements of one-way latency between the first and second nodes using the virtual clock, and generates a latency profile by interpolating the multiple measurements.

  • Patent number: 7254142
    Abstract: The method is for adjusting a bandwidth capacity of a dynamic channel in a network topology by allocating a bandwith value (b1) to the dynamic channel wherein the channel extends from a first node to a second node in a network topology. The traffic flow in the channel is measured to calculate a measured bandwidth value (B1). The allocated bandwidth value (b1) is dynamically adjusted to the measured bandwidth value (B1) so adjust the bandwidth (b1) to the actual bandwidth used.
