Congestion Games, Load Balancing, and Price of Anarchys speed, but it grows linearly with (or, more generally, as the .th power of) the number of clients matched to it. Many emerging Internet-centric applications such as peer-to-peer networks, multi-player online games and distributed computing platforms exhibit such interaction of self-interested user

Bandwidth Allocation in Networks: A Single Dual Update Subroutine for Multiple Objectivesd . ≤ . represent the capacity constraints. We consider the class of . utility functions, consisting of functions . that are symmetric, non-decreasing, concave, and satisfy .(0) = 0. We present a single dual update subroutine that results in a primal solution which is a logarithmic approximation, si

Limits and Power Laws of Models for the Web Graph and Other Networked Information Spaces link structure of existing nodes, and a certain number of additional random links are introduced. Our model parametrizes the number of random links, thereby allowing for the analysis of threshold behaviour. We consider infinite limits of graphs generated by our model, and compare properties of thes

Cuts and Disjoint Paths in the Valley-Free Path Model of Internet BGP Routingard edges. This model is motivated by BGP routing policies of autonomous systems in the Internet. Robustness considerations lead to the problem of computing a maximum number of disjoint paths between two nodes, and the minimum size of a cut that separates them. We study these problems in the valley-

A Distributed Algorithm to Find Hamiltonian Cycles in , Random Graphs finds a Hamiltonian cycle in . with high probability when ., and terminates in linear worst-case number of pulses, and in expected .(..) pulses. The algorithm requires, in each node of the network, only .(.) space and .(.) internal instructions.
