    摘要: A method for packet flow-rate control within a network node (4) comprised within a packet-switched communication network connection linking a sender (1) to a receiver (2), the said method comprising the following steps
    - computing the average arrival rate of packets since the last packet mark or drop event;
    - sending a congestion signal to the sender as soon as the computed packet arrival rate is above a predefined target rate;
    - repeating congestion signal sending until the sender receives at least a congestion signal and consequently reduces the sending rate.

    摘要: A method for estimating a round trip time, RTT, of a packet flow, comprising the steps of:
    - computing a periodogram P N based on N samples h 1 , h 2 ..h N of an inter-arrival time signal X between adjacent packets, X(t k ) = h k = t k - t k-1 , using a Lomb-Scargle method,
    - extracting a fundamental pulsation ω 0 out of said periodogram P N using a pattern matching technique,
    - determining the RTT out of said fundamental pulsation.
