Resumen
This paper presents a simple passive algorithm to
estimate the Round-Trip-Time (RTT) of a TCP connection in high
bandwidth-delay network scenarios. In these scenarios, a passive
RTT estimator that can be used on captured packet traces is a
useful tool for performance analysis. The algorithm is based on
observing periodic RTT patterns in a TCP connection that is not

This paper presents a simple passive algorithm to
estimate the Round-Trip-Time (RTT) of a TCP connection in high
bandwidth-delay network scenarios. In these scenarios, a passive
RTT estimator that can be used on captured packet traces is a
useful tool for performance analysis. The algorithm is based on
observing periodic RTT patterns in a TCP connection that is not
filling its bandwidth×delay product. The results are compared to
other passive methods such as the RTT of initial TCP handshake
or TCP Timestamp option samples. The algorithm is shown to be
effective and may be used in more scenarios than other methods
thus, it provides a valuable tool to improve the amount of TCP
connection whose RTT can be measured in a captured packet
trace. [--]
