    Network Bandwidth allocation with end-to-end QoS constraints and Revenue Sharing in Multidomain Federations

    Internet is evolving, traffic continues to grow, new revenue sources are sought by Network and Service Providers. Value added services with real time characteristics are likely to be common currency in the near future. Quality of Service (QoS) could allow Application/Service Providers (APs) to offer better services to the end...

    Fluid Limits Applied to Peer to Peer Network Analysis

    The objective of several techniques including fluid limits and mean field approximations is to analyze a stochastic complex system (e.g. Markovian) studying a simplified model (deterministic, represented by Ordinary Differential Equations (ODEs)). In this paper, the authors explore models proposed for the analysis of BitTorrent P2P systems and they provide...

    Optimizing Revenue for Bandwidth Auctions Over Networks With Time Reservations

    This paper concerns the problem of allocating network capacity through periodic auctions, in which users submit bids for fixed amounts of end-to-end service. The authors seek a distributed allocation policy over a general network topology that optimizes revenue for the operator, under the provision that resources allocated in a given...

    Distortions, Infrastructure And Labor Supply In Latin American Countries

    The author documents differences in labor supply between a set of Latin American countries and the U.S. in the period 1990-2005. These differences are mostly explained by large differences in female labor supply. In the U.S. the female labor force participation was 69% by 1990, while in Brazil and Mexico...

    Redistribution, Insurance And Incentives To Work In Latin American Pension Programs

    The authors present a new database of social security indicators for eleven Latin American countries designed to show how much they promise to pay in return to contributions. The indicators are based on micro-simulations according to existing norms. Their results indicate that most programs are progressive. In most programs, retirement...

    Throughput Prediction in Wireless Networks Using Statistical Learning

    The focus of this paper is on the estimation of throughput in wireless networks, more specifically on IEEE 802.11. The authors' proposal is based on active measurements and statistical learning tools. They present a methodology where the system is trained during short periods with application flows and probe packets bursts....

    Racial Inequality In The Uruguayan Labor Market: An Analysis Of Wage Differentials Between Afrodescendants And Whites

    Latin America is a region of sharp inequalities that are far from ethnically blind. In particular, there exists a significant socioeconomic gap between Latin Americans of European and the Afro-descendant and Indigenouos populations. Uruguay has usually been considered an exception to this pattern, although the lack of survey data about...

    Network Utility Maximization for Overcoming Inefficiency in Multirate Wireless Networks

    Wireless local area networks, in particular the ones based in the IEEE 802.11 standard, are nowadays used around the world to deliver Internet access, and are becoming increasingly prevalent. One of the crucial performance issues that these networks introduce is the possibility of having multiple transmission rates in the physical...

    International Commodity Prices, Trade And Poverty In Uruguay

    Commodity prices have risen sharply since 2006. This may benefit developing countries specialized on primary exports, but poverty may increase. Uruguay is a net exporter of primary products and a net importer of oil. With the aim of analyzing the impact of soaring commodity prices and policy options, the authors...

    The Search for QoS in Data Networks: A Statistical Approach

    New Internet services like video on-demand, high definition IPTV, high definition video conferences and some real time applications have strong QoS requirements regarding losses, delay, jitter, etc. This paper addresses the challenge of guaranteeing Quality of Service (QoS) in the Internet from a statistical point of view. Three lines of...

    Robust Routing Mechanisms for Intradomain Traffic Engineering in Dynamic Networks

    Internet traffic is highly dynamic and difficult to predict in current network scenarios. This makes of Traffic Engineering (TE) a very challenging task for network management and resources optimization. The authors study the problem of Intra-domain Routing Optimization under this traffic uncertainty. Recent works have proposed robust optimization techniques to...

    Network Bandwidth Allocation Via Distributed Auctions With Time Reservations

    This paper explains the problem of allocating network capacity through periodic auctions. Motivated primarily by a service overlay architecture, the authors impose the following conditions: fully distributed solutions over an arbitrary network topology, and the requirement that resources allocated in a given auction are reserved for the entire duration of...

    Auctions for Resource Allocation in Overlay Networks

    In recent years, many types of "Overlay" networks have been proposed for the Internet. These overlays include content delivery networks, peer-to-peer file sharing, some voice-over-IP services, and testbed networks such as PlanetLab. A particular architecture called Service Overlay Network (SON) has been proposed to deploy value-added Internet services with end-to-end...
