چکیده

This paper introduces a model to study the phenomenon of long range dependence. This model consists of an infinite superposition of independent Markovian ON/OFF– sources. A condition for assuring long range dependence is given and the Hurst parameter together with the correlation decay is derived for a specific example. We also give a physical interpretation of the existing long range dependence by means of the Ising model.

A Storage Model with High Rate and Long RangeDependent On / O Sources

We consider a uid queueing problem with an innnite reservoir with output rate C, fed by an innnite superposition of identical On/OO sources with large instantaneous bit rate h C. The On periods have innnite variance, generating Long Range Dependence. It is shown that the distribution of the stationary queue content at embedded time points is heavy tailed with innnite mean. It is explained why t...

A discrete-time ATM traffic model with long range dependence characteristics

This paper presents a novel discrete-time ATM traac model which exhibits a long range dependence character. The process results from the superposition of an innnite number of on/oo sources which have an increasing mean on and oo period duration. The condition under which the process has the long range dependence property is a simple function of the parameters of the on/oo sources. Moreover, the...

Neural Modelling of Ethernet Traffic over Atm Networks

The purpose of this paper is to present a method of modeling a superposition of individual Ethernet sources over an Asynchronous Transfer Mode (ATM) network through neural networks. It is proposed the two-state MMPP model (Markov Modulated Poisson Process) to approximate the aggregated ATM traffic because of its simplicity and analytical tractability. The neural network is able to calculate the...

The behaviour of the normalized variance of the multiplictiy distribution and the normalized transverse momentum fluctuations with centrality is naturally explained by the dependence on centrality of the number of clusters of color sources. This dependence predicts a nonmonotonic behaviour with centrality of the multiplicity associated to high p T events. The clustering of color sources is also...

Bounds for the Tail Distribution in a Queue with the Superposition of General Periodic Markov Sources

In this paper, we derive the bounds formulas for the asymptotic tail distribution in a queue whose arrival process is a superposition of general periodic Markov sources. Note that we make no assumption for the structure of the general periodic Markov sources except that the underlying Markov chains are irreducible. The periodic source model in this paper is thus rather general. Taking initial s...
