TLDR
The paper proposes substitution of packet loss parameterP pl in ITU-T E-Model by effective packet loss P plef incorporating network jitter, a jitter buffer size and a packet size as additional input parameters for E- model.Abstract:
The paper deals with an influence of network jitter on effective packet loss in dejitter buffer We analyze behavior of jitter buffers with and without packet reordering capability and quantify the additional packet loss caused by packets dropped in buffer on top of the measured network packet loss We propose substitution of packet loss parameterP pl in ITU-T E-Model by effective packet loss P plef incorporating network jitter, a jitter buffer size and a packet size as additional input parameters for E-Modelread more

Evaluating QoE in VoIP networks with QoS mapping and machine learning algorithms
TL;DR: This work will achieve a more accurate evaluation of the QoE in VoIP by using QoS parameters, clarify the influence of IP network environments, noise and echo impairments on the quality and reliability of VoIP traffic, and provide QoS parameter requirements for the VoIP application that runs at the desiredQoE level.

Model to Increase the Number of Output States of a Random Variable Using a Histogram Based PDF
TL;DR: This model that generates practically an unlimited set of possible output states of the random variable Y is applied on a packet generator that generates IPTV inter-departure times of an MPEG2-TS H.264 VBR based video source.

Fractal analysis and modeling of VoIP traffic
TL;DR: It is argued that the call hold times follow heavy-tailed distributions rather than exponential distributions and the generalized Pareto distribution is proposed for modeling the call holding times.

E-model mos estimate improvement through jitter buffer packet loss modelling
TL;DR: Analysis of dependence of MOS as a voice call quality (QoS) measure estimated through ITU-T E-model under real network conditions with jitter found that network jitter effects via excess packet loss complementing measured network packet loss is significant.
E-model modification for case of cascade codecs arrangement
TL;DR: A new modification of E-model, that takes into consideration the cascade codecs arrangement, is presented and the proposed a correction function improves the current computational non-intrusive approach described in recommendation ITU-T G.107, so-called E- model.

Loss probability behavior of Pareto/M/1/K queue
Y. Koh,Kiseon Kim +1 more
TL;DR: This letter proposes a model for the loss probability of Pareto/M/1/K as a function of the buffer size K and the geometric parameter and shows the big discrepancy between the asymptotic and the actual loss probability.

S. T. Mirtchev,Rossitza Goleva +1 more
TL;DR: A real time trace simulation model is proposed for estimating the steady-state probability showing the tail-raising effect, loss probability, delay of the Pareto/D/1/k queue and can be used to study the long- tailed queueing systems.
