Abstract:
The self-similarity (S2) filter is proposed for real-time applications. It can be used independently or as an
extra component for the enhanced RTPD (real-time traffic pattern detector) or E-RTPD. The S2 filter
basis is the "asymptotically second-order self-similarity" concept (alternatively called
statistical 2nd OSS or S2nd OSS) for stationary time series. The focus is the IAT (inter-arrival times)
traffic. The filter is original because similar approaches are not found in the literature for detecting selfsimilar
traffic patterns on the fly. Different experiments confirm that with help form the S2 filter the FLC
(Fuzzy Logic Controller) dynamic buffer size tuner control more accurately. As a result the FLC improves
the reliability of the client/server interaction path leading to shorter roundtrip time (RTT).
