This paper studies network resource allocation between users that manage multiple
connections, possibly through different routes, where each connection is subject to …

Rate allocation among a fixed set of end-to-end connections in the Internet is carried out by
congestion control, which has a well established model: it optimizes a concave network …

This paper studies partial differential equation (PDE) models for the dynamics of peer-to-
peer (P2P) file-sharing networks. Using as independent variables time and a fluid measure …

In this paper, we study how to achieve network utility maximization (NUM) in flow-level
wireless networks, which can be characterized by the random arrivals and departures of flow …

In this paper, we develop a new approach to studying the asymptotic behavior of fluid model
solutions for critically loaded processor sharing queues. For this, we introduce a notion of …

In this paper we analyze the dynamics of P2P file exchange networks, considering both
queueing and fluid models. In such systems, the service rate depends on one mostly fixed …

This work concerns the asymptotic behavior of critical fluid model solutions for a multiclass
processor sharing queue under general distributional assumptions. Such critical fluid model …

We consider a queueing model where documents are simultaneously transferred over a
communication network. The bandwidth allocated to each document transfer is assumed to …

En esta tesis, se analizan varios problemas de asignación de recursos que surgen en el
estudio de los sistemas de telecomunicaciones. En particular, nos centramos en las redes …

This paper studies the dynamics of the number of active end-to-end connections (flows) in a
network, assuming individual flow rates are determined by standard models of TCP …
