Abstract:
1. A method comprising: receiving a signal at a receiving terminal from a network, the signal comprising a plurality of data elements; determining a transmission delay of at least one data element of the plurality of data elements; estimating a first component of the transmission delay, the first component including a clock skew delay component of the transmission delay; determining a second component of the transmission delay by removing the first component including the clock skew delay component of the transmission delay from the transmission delay; determining a receiver jitter buffer delay to be applied at the receiving terminal between receiving one of said plurality of data elements at the receiving terminal from the network and outputting the data element from the receiving terminal, the determining the receiver jitter buffer delay based on the second component of the transmission delay and not based on the first component including the clock skew delay component of the transmission delay; and determining a network propagation state of the network based on the second component, and updating statistics associated with the determined network propagation state of the network.
