摘要:
A method for packet flow rate control within a network node (4) receiving at least a traffic flow from a sender (1), comprising the following steps: - computing the average rate at the end of a cycle comprising an initial value of packet number; - updating the value of packet number per cycle in function of the computed average rate with respect to a target flow rate.

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.
