Abstract:The focus of current research is how Self-similarity impacts network performance. A queuing delay jitter model, based on FBM for self-similar network, is proposed and self-similar traffic as input on the impact of the delay jitter of queuing system is discussed, which is important. Theory fractional traffic and actual measured traces are used to simulate experiment. Simulation confirms the correctness and efficiency of these results. The experimental results demonstrate that the degree of the long-range dependence for the self-similar traffic has quite a different impact on the delay jitter of queuing system, especially on the condition of a large buffer size. The state changes of long-range dependence is related to the parameters of queuing system. These findings are new, which is an important reference for the performance evaluation of real-time network .
