Optimizing TCP Receive Performance

Willy Zwaenepoel, Aravind Menon

The performance of the networking stack in an operating system depends on the overhead incurred by two of its components: the per-byte overhead incurred in data-touching operations, and the per-packet overhead of protocol processing and other operating sys ...

Loss-resilient window-based congestion control

Pascal Frossard, Christophe De Vleeschouwer

This paper addresses the problem of fair allocation of bandwidth resources on lossy channels in hybrid heterogeneous networks. It discusses more particularly the ability of window-based congestion control to support non-congestion related losses. We invest ...

Performance Analysis of Self Limiting Epidemic Forwarding

Jean-Yves Le Boudec, Alaeddine El Fawal

Self limiting epidemic forwarding is a method of epidemic information dissemination in wireless ad-hoc networks that achieves congestion control by limiting spread (i.e. the number of nodes that receive a given message) and injection rate in order to prese ...

Controlled Use of Excess Backbone Bandwidth for Providing New Services in IP-Over-WDM Networks

Patrick Thiran

We study an approach to quality-of-service (QoS) that offers end-users the choice between two service classes defined according to their level of transmission protection. The fully protected (FP) class offers end-users a guarantee of survivability in the c ...

Delay aspects in Internet telephony

Catherine Boutremans

In this work, we address the transport of high quality voice over the Internet with a particular concern for delays. Transport of interactive audio over IP networks often suffers from packet loss and variations in the network delay (jitter). Forward Error ...

Packet scale rate guarantee for non-FIFO nodes

Jean-Yves Le Boudec

Packet Scale Rate Guarantee (PSRG) is a generic node model which underlies the definition of Expedited Forwarding (EF) proposed in the context of Internet Differentiated Services. For the case of FIFO nodes, PSRG is equivalent to the well-understood concep ...

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

Jean-Yves Le Boudec, Milan Vojnovic

We consider unicast equation based rate control, where a source estimates the loss event ratio p, and, primarily at loss events, adjusts its sending rate to f(p). Function f is assumed to represent the loss-throughput relation that TCP would experience. Wh ...

Observations on Equation-Based Rate Control

Jean-Yves Le Boudec, Milan Vojnovic

We consider unicast equation based rate control defined as follows. A source adjusts its rate primarily at loss events to f(p) where p is an estimator of loss event ratio. Function f is typically the loss-throughput formula of a TCP source. In absence of l ...

A flow-based model for TCP traffic in an IP backbone network

We present a model of TCP flows suited to Internet backbone traffic, where links are usually not congested. We characterize the traffic using information on flows, i.e., arrival time, size, and duration. The major contribution of this paper is a model capt ...
