A Novel Scheduler for a Low Delay Service Within Best-Effort

Jean-Yves Le Boudec, Patrick Thiran, Paul Hurley

We present a novel scheduling algorithm, Duplicate Scheduling with Deadlines (DSD). This algorithm implements the ABE service which allows interactive, adaptive applications, that mark their packets green, to receive a low bounded delay at the expense of m ...

A Protection-based Approach to QoS in Packet over Fiber Networks

Patrick Thiran

We propose a novel approach to Quality of Service, intended for IP over SONET (or IP over WDM) networks, that offers end-users the choice between two service classes defined according to their level of transmission protection. The first service class (call ...

ABE: providing a low-delay service within best effort

Jean-Yves Le Boudec, Patrick Thiran, Paul Hurley

Alternative best effort (ABE) is a novel service for IP networks, which relies on the idea of providing low delay at the expense of possibly less throughput. The objective is to retain the simplicity of the original Internet single-class best-effort servic ...

Combining IntServ and DiffServ under Linux

Combining Integrated Services ([1], [5]) QoS mechanisms for end-to-end signaling at hosts and Differentiated Services ([2], [10]) QoS mechanisms in the network core is one proposal for overcoming the limitation of either mechanisms when applied alone ([8]) ...

Delay Jitter Bounds and Packet Scale Rate Guarantee for Expedited Forwarding

Jean-Yves Le Boudec

We consider the definition of the Expedited Forwarding Per-Hop Behaviour (EF PHB) as given in RFC 2598, and its impact on worst case end-to-end delay jitter. On one hand, the definition in RFC 2598 can be used to predict extremely low end-to-end delay jitt ...

Video multicast over fair queueing networks

Martin Vetterli

We consider the problem of video multicast over networks that enforce fair bandwidth allocations in the routers. State-of-the-art layered IP multicast systems perform well for moderately sized sessions, but suffer from three basic problems that prevent the ...

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 ...

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 ...
