Accurate modeling of VoIP traffic QoS parameters in current and future networks with multifractal and Markov models

摘要: Abstract In this paper, we analyze the jitter and packet loss behavior of Voice over Internet Protocol (VoIP) traffic by means network measurements simulations results. As result these analyses, provide a detailed characterization accurate modeling Quality Service (QoS) parameters. Our studies have revealed that VoIP can be modeled self-similar processes with short range dependence (SRD) or long (LRD). The discovery LRD (a kind asymptotic fractal scaling) in was followed further work shows evidence multifractal behavior. implication behaviors for other interactive multimedia services is receiver de-jitter buffer may not large enough to mask characteristics. On hand, use description based on microscopic macroscopic behaviors, where 2-state 4-state Markov chains, respectively. Based above mentioned points, present methodology simulating loss. Besides, found relationships between Hurst parameter (H) rate (PLR); are voice power-law function, characterized three fitted proposed models used to: (i) design buffer, (ii) implement synthetic generator data traces, traces as test vectors carry out performance evaluation system, (iii) effective schemes recovery.
