The dimensioning of telecommunication networks that carry elastic traffic requires the fulfillment of two conflicting goals: maximizing the total network throughput and providing fairness to all flows. Fairness in telecommunication network design is usually provided using the so-called max-min fairness (MMF) approach. However, this approach maximizes the performance of the worst (most expensive...

Modern telecommunications networks are designed in such a way that to accommodate a mix of heterogeneous wireless networks of traffic classes to perform different services. Traffic models are important to analyze the performances of telecommunication systems namely traffic, interference and channel estimation. This paper provides an approach for evaluating the channel availability and predictin...

-Real traffic flows are captured in various network environments, such as Academic, Core, Dial-Up, Transit, and Leased Line. Their statistical properties are analyzed. IAT (Inter-Arrival Time Histogram) histograms, IAT cumulative distribution probabilities, packet size histograms, packet size cumulative distribution probabilities, the influence of traffic aggregation on burstiness, and burstine...

Modern telecommunication networks are designed to support converged traffic including voice, data and video. [1] One major feature of these networks is that the input traffic is usually highly bursty.[2] Also, because these networks operate in a packet switching mode, there is usually a strong correlation between packet arrivals. Thus, for these networks the traditional Poisson traffic model ca...

The energy consumption in telecommunication networks is expected to grow considerably, especially in core networks. In this chapter, optimization of energy consumption is approached from two directions. In a first study, multilayer traffic engineering is used to assign energy-efficient paths and logical topology to IP traffic. The relation with traditional capacity optimization is explained, an...

Today, a large part of the teletraffic carried by the Internet is generated by file-sharing applications based on the peer-to-peer (P2P) paradigm. This paper considers teletraffic measurements and classification, with an emphasis on techniques which can be used to detect P2P traffic with “conventional” PC hardware, and shows some initial results of such measurements, done at the Telecommunicati...

This paper proposes an approach to the management of traffic in telecommunication networks. It was motivated by the growing need for Intelligent Network Management in current Telecommunication Networks such as PSTN, ISDN or transmission networks. The goal is to constantly act upon the network in order to control the traffic flow, trying to maximize the number of calls that reach destination or ...

Telecommunication traffic (voice, data etc.) is increasing day by day. So to meet the capacity demand, in this paper we have designed and verified a high capacity optical fiber communication system through simulation. We simulated a 40 Gbps single optical fiber link for telecommunication traffic transmission which could be possible to implement in developing countries with few modifications in ...

This paper proposes a macroscopic fluid dynamic model dealing with the flows of information on a telecommunication network with sources and destinations. The model consists of a conservation law for the packets density and a semilinear equation for traffic distributions functions, i.e. functions describing packets paths. We describe methods to solve Riemann Problems at junctions assigning diffe...
