A novel R2-FLC dynamic buffer size tuner to support time-critical applications over the Internet by improving logical channel fault tolerance to shorten roundtrip time

This paper has two original and important proposals: a) the self-similarity (S²) traffic filter for real-time applications and b) the R²-FLC (reconfigurable real-time fuzzy logic controller) for on-line dynamic buffer size tuning. Inclusion of the S² filter into the extant RTPD (real-time traffic detector) model creates the novel enhanced RTPD (ERTPD) framework. The R²-FLC uses the ERPTD to detect the current traffic pattern of a logical channel on the fly and auto-tunes accordingly. The auto-tuning process, which is system reconfiguration in the R²-FLC context, neutralizes the ill effects by changing traffic patterns on the accuracy and stability of the dynamic buffer size tuning process.
