End-to-end congestion control for tcp-friendly flows with variable packet size

Jean-Yves Le Boudec, Jörg Widmer, Catherine Boutremans

Current TCP-friendly congestion control mechanisms adjust the packet rate in order to adapt to network conditions and obtain a throughput not exceeding that of a TCP connection operating under the same conditions. In an environment where the bottleneck res ...

On the Long-Run Behavior of Equation-Based Rate Control

Jean-Yves Le Boudec, Milan Vojnovic

We consider unicast equation-based rate con-trol, where, at some points in time, a sender adjusts its rate to f(p,r), where p is an on-line estimate of the loss-event rate observed by this source, r of the average round-trip time, and f is a TCP throughput ...

Optimal Power Control, Scheduling and Routing in UWB Networks

Jean-Yves Le Boudec

Ultra-Wide Band (UWB) is an emerging wireless physical layer technology that uses a very large bandwidth. We are interested in finding the design objectives of the medium access (MAC, namely, power control and scheduling) and routing protocols of a multi-h ...

Route Driven Gossip: Probabilistic Reliable Multicast in Ad Hoc Networks

Jean-Pierre Hubaux, Jun Luo, Patrick Eugster

Traditionally, reliable multicast protocols are deterministic in nature. It is precisely this determinism which tends to become their limiting factor when aiming at reliability and scalability, particularly in highly dynamic networks, e.g., ad hoc networks ...

Scalable Resource Reservation for the Internet

For some time now, the design of architectures for providing dependable Quality of Service (QoS) on multimedia networks has been a busy topic in academia and industry. In this work we look at practical aspects of Quality of Service, and in particular at re ...

A Performance Comparison of Homeless and Home-based Lazy Release Consistency Protocols in Software Shared Memory

Willy Zwaenepoel

In this paper, we compare the performance of two multiple-writer protocols based on lazy release consistency. In particular, we compare the performance of Princeton’s home-based protocol and TreadMarks’ protocol on a 32-processor platform. We found that th ...
