Current network planning and design methods use the average delay, packet loss and throughput as metrics to optimize the network cost and performance. New...

The topic of this paper is the evaluation of QoS parameters in live Pre-Wimax environments. The main contribution is the validation of an analytical delay-ji...

Traditionally, IP Network planning and design is mostly based on average delay or loss constraints which can often be easily calculated. Jitter, on the othe...

The convergence of different classes of traffic with different priorities over the wire- less network has become a reality. To insure that the users of key ...

In this paper, we study the problem of determining the capacity requirements for applications that require QoS guarantees. We consider three kinds of source ...

In this article we extend previous work showing that DiffServ can provide some QoS guarantees to both real-time and non real-time traffic in the event of th...

As ISP’s and Telco’s converge towards all-IP network infrastructures, the problem of QoS becomes more acute. To address it, operators are deploying differen...

The increase of bandwidth demand for new Internet applications suggests mapping directly IP over the WDM layer. Since reliability is such a critical issue i...

This paper presents a new heuristic to solve efficiently the problem of dimension- ing large-size hybrid optoelectronic networks with grooming. It is modele...

We consider the design of a hybrid opto-electronic network with grooming. We propose a model in which we take into account the fact that grooming traffic req...
