Abstract: FLC (Fuzzy Logic Control) [11] has been considered for IC (Intelligence Control). It is a methodology used to design robust systems that provide factors such as system nonlinearity, parameter uncertainty, measurement and modelling imprecision. In fact, fuzzy logic control showed extraordinary and mature control performance in accuracy, transient response, robustness and stability [12], [13]. Fuzzy logic control use to avoid buffering using by avoiding variation of queuing delay (Queuing jitter) due to the dynamics queue length. Queuing flows can be buffered on the receiving side before being delivered. Buffering them does not affect the reliability or bandwidth, and increases the delay, but it smooth out the jitter.

Keywords: Congestion control, fuzzy logic control, quality Of service, max-min fairness, robustness, traffic management, buffering, jitter.
