Abstract
An intermediary node is adapted for receiving a sequence of packets from a server, wherein the intermediary node comprises a time estimator adapted for performing the following steps—resolving the sequence number (k) and time of arrival to the intermediary node for at least a plurality (q) of incoming packets; establishing the frame period of the incoming packets (T); establishing a sequence of normalized packet arrival times (ek) as corresponding to the established frame period (T); calculating the relative arrival time (rtrec, k) of the plurality (q) of incoming packets in relation to the normalized packet arrival times; creating a cumulative density function (CDF) for a given sequence of packets; and establishing the threshold value for the relative arrival time (rtPL) yielding the predefined packet loss (PL) based on the cumulative density function (CDF).
