The SOREN Project: Server Selection in Emerging Environments

Abstract

Content delivery networks comprise origin servers, replicated servers, and proxy servers that work in combination to deliver content to clients. A central issue in the design of effective content delivery networks is the mechanism by which a collection of servers is selected to deliver content to a particular client.

The SOREN project seeks to develop algorithms and protocols for the server selection problem in a variety of environments. The project has two themes: a focus on the global issues that arise when many clients make use of a selection scheme, and explicit consideration of the characteristics of particular applications (rather than a generic single-server-single-client abstraction).

This talk will describe current work in the SOREN project, including server selection for multicast video-on-demand servers, server selection in parallel download situations, and server selection for multiple-source delivery.
