Explicit window-based transport control protocols in lossy environments

Pascal Frossard, Christophe De Vleeschouwer

This paper addresses efficient packet loss recovery by retransmission in window-based congestion control protocols. It builds on explicit congestion control mechanisms to decouple the packet loss detection from the congestion feedback signals. Implicit alg ...

Bits of Internet traffic control

Milan Vojnovic

In this work, we consider four problems in the context of Internet traffic control. The first problem is to understand when and why a sender that implements an equation-based rate control would be TCP-friendly, or not—a sender is said to be TCP-friendly if ...

Bandwidth Allocation for Non-Responsive Flows with Active Queue Management

This paper addresses the problem of configuring active queue management systems (e.g. WRED and RIO) for service level specifications in Internetworks. In particular, we focus on Assured Forwarding (AF) for non-responsive flows in Differentiated Services ne ...

Broadcast quality video over IP

We consider the problem of designing systems for the transmission of high-quality video signals over certain high-speed segments of the public IP network. Our most important contribution is the definition of a network/coder interface for IP networks which ...

ABE: Providing a Low Delay Service Within Best-Effort

Jean-Yves Le Boudec, Patrick Thiran, Paul Hurley

We propose Alternative Best-Effort (ABE), a novel service for IP networks, which retains the simplicity of the original Internet single class, best effort service, while providing low delay to interactive, adaptive applications. With ABE, applications choo ...

The Asymmetric Best-Effort Service

Jean-Yves Le Boudec, Ljubica Blazevic

We present Asymmetric Best-Effort, a novel service to provide a ``throughput versus delay jitter'' differentiated service for IP packets. With this service, every best effort packet is marked as either green or blue. Green packets, typically sent by real-t ...

The Alternative Best-Effort Service

Jean-Yves Le Boudec, Patrick Thiran, Paul Hurley

Alternative Best-Effort (ABE) is a novel service for IP networks which offers applications the choice between receiving a lower end-to-end delay and receiving more overall throughput. Every best effort packet is marked as either green or blue. Green packet ...

Regulation of a Connection Admission Control Algorithm

Jean-Yves Le Boudec, Patrick Thiran

Connection Admission Control (CAC) algorithms are used to decide whether an incoming connection should be accepted or rejected in a node of a network offering reservation based services in order to maintain the guaranteed Quality of Service (QoS) in the ne ...

A comparison of ABR and UBR to support TCP traffic

Jean-Yves Le Boudec

We compare the performance of ABR and UBR for providing high-speed network interconnection services for TCP traffic. We test the hypothesis that UBR with adequate buffering in the ATM switches results in better overall goodput for TCP traffic than explicit ...
