Mailbox switch: a scalable two-stage switch architecture for conflict resolution of ordered packets
Abstract-- Traditionally, conflict resolution in an inputbuffered switch is solved by finding a matching between inputs and outputs per time slot. To do this, a switch not only nee...

Fast, Fair, and Efficient Flows in Networks
Abstract. We study the problem of minimizing the maximum latency of flows in networks with congestion. We show that this problem is NP-hard, even when all arc latency functions ar...

A Bidding Algorithm for Optimized Utility-Based Resource Allocation in Ad Hoc Networks
Abstract-- This article proposes a scheme for bandwidth allocation in wireless ad hoc networks. The quality of service (QoS) levels for each end-to-end flow are expressed using a r...
