Abstract:
Network operators often attempt to analyze traffic in the middle of their networks for various purposes. In such traffic analysis, the estimation of Round-Trip Time (RTT) is indispensable. Primarily, the RTT estimation is performed by consulting the relationship between a request and its response, such as a data segment and the associated ACK segment. However, in the middle of Internet, it is common that a network operator monitors traffic only in one direction. In such a case, an operator is required to estimate RTT from unidirectional packet traces. So far, several methods have been proposed for RTT estimation from unidirectional traces. In this paper, we adopt the Lomb periodogram method and apply it to various TCP traces, collected through Ethernet or wireless LAN, with different congestion control algorithms. As a result, the method can estimate RTT roughly, but the results are not accurate enough for subtle analysis, such as congestion window estimation.
