Stochastic Analysis of Some Expedited Forwarding Networks

Jean-Yves Le Boudec, Milan Vojnovic

We consider stochastic guarantees for networks with aggregate scheduling, in particular, Expedited Forwarding (EF). Our approach is based on the assumption that a node can be abstracted by a service curve, and the input flows are regulated individually at ...

Generic 3D ball animation model for networked interactive VR environments

Daniel Thalmann

The paper describes a versatile, robust, and parametric ball animation model that can be used in many types of interactive virtual reality (VR) environments. The generic model is particularly useful for animation of ball-like objects such as tennis balls a ...

Some properties of variable length packet shapers

Jean-Yves Le Boudec

The min-plus theory of greedy shapers has been developed after Cruz's results on the calculus of network delays. An example of greedy shaper is the buffered leaky bucket controller. The theory of greedy shapers establishes a number of properties; for examp ...

Population dynamics of spiking neurons: fast transients, asynchronous states and locking

Wulfram Gerstner

An integral equation describing the time evolution of the population activity in a homogeneous pool of spiking neurons of the integrate-and-fire type is discussed. It is analytically shown that transients from a state of incoherent firing can be immediate. ...

To code or not to code

Martin Vetterli, Michael Christoph Gastpar, Bixio Rimoldi

The theory and practice of digital communication during the past 50 years has been strongly influenced by Shannon's separation theorem. While it is conceptually and practically appealing to separate source from channel coding, either step requires infinite ...

A Delay Bound for a Network with Aggregate Scheduling

Jean-Yves Le Boudec, Félix Farkas

Given the increasing demand for services that can guarantee a maximum end-to-end delay in the Internet, it is important to understand the behaviour of different existing networks. We consider networks that implement scheduling per aggregate flow. We give a ...

Processing Transactions over Optimistic Atomic Broadcast Protocols

André Schiper, Fernando Pedone

Atomic broadcast primitives allow fault-tolerant cooperation between sites in adistributed system. Unfortunately, the delay incurred before a message can be delivered makes it difficult to implement high performance, scalable applications on top of atomic ...

Using Optimistic Atomic Broadcast in Transaction Processing Systems

André Schiper, Fernando Pedone

Atomic broadcast primitives are often proposed as a mechanism to allow fault-tolerant cooperation between sites in a distributed system. Unfortunately, the delay incurred before a message can be delivered makes it difficult to implement high performance, s ...

Optimal Smoothing for Guaranteed Service

Jean-Yves Le Boudec, Olivier Verscheure

We consider a scenario where multimedia data is sent over a network offering a guaranteed service such as ATM VBR or the guaranteed service of the IETF. A smoothing device writes the stream into a networking device for transmission, possibly with some pre- ...

User-Oriented QoS in Packet Video Delivery

Jean-Pierre Hubaux, Olivier Verscheure

We focus on packet video delivery, with an emphasis on the quality of service perceived by the end-user. A video signal passes through several subsystems, such as the source coder, the network and the decoder. Each of these can impair the information, eith ...
