The role of the Information and Communication Technology sector on productivity and economic growth is constantly increasing and, due to its pervasiveness, ...

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...

<p>With the increasing concern for global warming, the impact of Internet power consumption is gaining interest. In this paper, we explore, for the first ti...

The issue of Internet energy consumption and its contribution to global warming has been gaining importance lately. In this paper we present a compilation of...

This paper deals with the design and dimensioning of a novel survivable optical network structure, called Petaweb, that can reach a total capacity of severa...

In this paper, we evaluate the impact of the wireless channel and physical layer parameters on the performance of VoIP traffic in IEEE 802.11g networks. The ...

In this paper we analyze the trade-off between admission costs and receiver rewards of TCP Tahoe flows competing for buffer space. Since the buffer space is...

This paper explores the design modelling issues of the Petaweb, an optical network architecture that provides fully meshed connectivity between electronic...

We propose a hybrid routing scheme that combines traditional shortest-path based OSPF mechanisms as well as a new form of explicit routing executed at the ...

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 manuscript we tackle the optimal upgrade of an innovative optical transport network architecture called the Petaweb, which has a particular composite...

This paper addresses the structural optimization of a next generation optical, lattice based, yottabit-per-second transport network topology, called the <i>...

This paper presents the design and dimensioning optimization of a novel optical network structure, called the PetaWeb, having a total capacity of several Pb...

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 proposes an efficient heuristic to solve the topological design of a next generation optical network that provides fully meshed connectivity betw...

This paper deals with the topological design of a next generation optical network that provides fully meshed connectivity between electronic edge nodes. Suc...

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