ABSTRACT
The trafc to be analyzed was captured using the tcpdump utility (Brenner 1997). It spanned over approximately 5 h from a busy time interval of the day. The data capture was done between 11:38 and 16:47 on October 12, 2005 on the premises of the AccessNet, Bucharest (Rothenberg 2006). The network architecture comprises around 20 network stations connected to a router. The captured trafc was split into ve parts of an hour each. Every sequence contains 36,000 measurements, and every measurement represents the number of packages sent through the network at every 100 ms. Note that, for time series of such a large horizon, the graphical estimators (domain rescaling and dispersion-time diagram) become quite powerful, thus rendering the self-similarity degree quite precise.
