METHOD FOR ESTIMATING A ROUND TRIP TIME OF A PACKET FLOW

摘要

A method for estimating a round trip time, RTT, of a packet flow, comprising the steps of : - computing a periodogram PN based on N samples h1, h2..hN of an inter-arrival time signal X between adjacent packets, X(tk) = hk = tk - tk-1, using a Lomb-Scargle method; - extracting a fundamental pulsation ?0 out of said periodogram PN using a pattern matching technique; - determining the RTT out of said fundamental pulsation.
