A Novel real-time self-similar traffic detector/filter to improve the reliability of a TCP based end-to-end client/server interaction path for shorter roundtrip time

The self-similarity ( 2 S ) 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 2 S filter basis is the “asymptotically second-order self-similarity” concept (alternatively called statistical OSS nd 2 or OSS S nd 2 ) 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 2 S 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).
