Abstract
Reanalyze 12traces ofround-trip Internet packet delay. We find that these traces, when viewed as time series data, often etilbit Hurst parameter (H) estimates greater than 0.5, in- dicating long-range dependence. Several traces, however, are not well-modeled with a constant .H. We discuss in detail our analytical methods and the robustness of empirical estima- tors of If under conditions of non-negligible packet loss. Our results indicate that Internet delay is bursty across multiple time scales, which implies that end-user quality of service in the Internet is likely to be impacted by long periods of very large and/or highly variable delays.
