Leveraging Network and Traffic Measurements for Content Distribution and Interpersonal Communication Services With Sufficient Quality
In this paper, the authors discuss research problems for enabling content distribution and supporting real-time interpersonal communication services (e.g., voice and video) over best effort networks with sufficient quality. They take a practical view of content distribution and quality, and this is the reason for the term "Sufficient". They argue that the understanding of quality as perceived by the user is a key factor in this context, but also that the understanding of context dependence is a key factor for delivering services which are "Good enough" to make the user satisfied. They base their assumptions upon results from the Celtic TRAMMS project, and they describe how to leverage upon the framework for traffic measurements that was built up in that project.
