Buffer optimization based on critical path analysis of a dataflow program design

Marco Mattavelli, Simone Casale Brunet

The trade-off between throughput and memory constraints is a common design problem in embedded systems, and especially for streaming applications, where the memory in question usually occurs in the form of buffers for streams of data. This paper presents a ...

Multi-path content delivery: Efficiency analysis and optimization algorithms

The paper studies the benefits of multi-path content delivery from a rate-distortion efficiency perspective. We develop an optimization framework for computing transmission schedules for streaming media packets over multiple network paths that maximize the ...

Manifest File Updates for Network Streaming of Coded Video Data

Ying Chen

In one example, a device for retrieving multimedia data, the device comprising one or more processors configured to retrieve data of a first segment of a representation of multimedia content in accordance with data of a copy of a manifest file stored by th ...

In-Network Packet Scheduling and Rate Allocation: A Content Delivery Perspective

We investigate two important problems in media delivery via active network agents. First, we consider streaming multiple video assets over a shared backbone network through an intermediate proxy-server to a set of receiving clients. The proxy is located at ...

Heterogeneous Gossip

Rachid Guerraoui, Anne-Marie Kermarrec, Maxime Monod, Davide Frey

Gossip-based information dissemination protocols are considered easy to deploy, scalable and resilient to network dynamics. Load-balancing is inherent in these protocols as the dissemination work is evenly spread among all nodes. Yet, large-scale distribut ...

User Performance in Interaction with Web-GIS: A Semi-Automated Methodology Using Log-Files and Streaming-Tools

François Golay, Jens Ingensand

This paper describes a framework of methods for the measurement and evaluation of users' performance in interaction with a web-GIS. The framework involves testing of a system with real-world users, streaming of the user's screen during the evaluation and t ...

Network coding: from theory to media streaming

Pascal Frossard, Nikolaos Thomos

Network coding has recently emerged as an alternative to traditional routing algorithms in communication systems. In network coding, the network nodes can combine the packets they receive before forwarding them to the neighbouring nodes. Intensive research ...

Media coding for streaming in networks with source and path diversity

Pascal Frossard, Nikolaos Thomos

Novel network architectures such as overlay networks offer significant diversity that can compensate for the lack of strict quality of service in today's communication infrastructures. In order to take advantage of this diversity for delay-sensitive media ...

Gossiping Capabilities

Rachid Guerraoui, Anne-Marie Kermarrec, Maxime Monod, Davide Frey

Gossip-based protocols are now acknowledged as a sound basis to implement collaborative high-bandwidth content dissemination: content location is disseminated through gossip, the actual contents being subsequently pulled. In this paper, we present HEAP, HE ...
