Caching Dynamic Web Content: Designing and Analysing an Aspect-Oriented Solution

Willy Zwaenepoel, Sumit Mittal

Caching dynamic web content is an effective approach to reduce Internet latency and server load. An ideal caching solution is one that can be added transparently by the developers and provides complete consistency of the cached documents, while minimizing ...

Playback Delay and Buffering Optimization in Scalable Video Broadcasting

Pascal Frossard, Jean-Paul Wagner

This paper addresses the problem of optimizing the playback delay experienced by a population of heterogeneous clients, in video streaming applications. We consider a typical broadcast scenario, where clients subscribe to different portions of a scalable v ...

Real-Time Interaction over the Internet: Model for QOS Adaptation

Denis Gillet, Christophe Salzmann, Philippe Müllhaupt

Real-time Interaction over the Internet (RTI2) is an Internet service that is required typically by remote experimentation applications. From a quality of service (QoS) point of view, RTI2 has constraints that differ from usual real-time multimedia service ...

Optimal FEC Rate for Media Streaming in Active Networks

Pascal Frossard, Dan Jurca

This paper addresses the problem of optimal channel rate allocation for media streaming in active networks, where intermediate nodes are able to perform basic FEC decoding/encoding operations. FEC performance is analyzed in the case of hop-by-hop FEC prote ...

Distortion-Buffer Optimized TCP Video Streaming

Pascal Frossard

This paper presents a distortion optimized streaming algorithm for on-demand streaming of multimedia. Given the pre-encoded packets of a multimedia stream, we propose an algorithm for selecting an appropriate subset of these packets such that the overall c ...

Reconfigurable Coprocessor for Media Streaming

Sébastien Bilavarn

The development of more processing demanding video standards on one hand and the popularity of mobile devices such as digital cameras or wireless videophones on the other hand introduce a need of optimization at the processor level. Reconfigurable systems ...

A Flexible and Efficient Application Programming Interface (API) for a Customizable Proxy Cache

Willy Zwaenepoel

This paper describes the design, implementation, and performance of a simple yet powerful Application Programming Interface (API) for providing extended services in a proxy cache. This API facilitates the development of customized content adaptation, conte ...

Batched Patch Caching for Streaming Media

Pascal Frossard

We elaborate on a scheme that combines batch patching at an origin server and prefix/interval caching at an edge server receiving the clients' requests. We derive a cost function that factors in the aggregate backbone rate, the cache occupancy and the disk ...
