SØREN Server Selection Project

Project Overview

Timely delivery of information from content servers to clients is now clearly one of the primary roles of ubiquitous networking. As the number of people seeking information increases, scalability of information delivery services becomes an important issue. Server replication is one common technique used by service providers to accommodate increasing demands. Effective server replication, however, demands appropriate server selection approaches, without which the full benefits of replication are not realized. The focus of the SØREN Server Selection Project is the design and evaluation of server selection approaches for wide-area services, particularly in the context of future networking and service environments.

The SØREN project is supported by Sprint Advanced Technology Labs, NSF and DARPA.

Why SØREN? No, it isn't an acronym (yet). Søren Kierkegaard, a 19th century Danish philosopher, is regarded as the "father of existentialism". In existentialism, the individual bears ultimate responsibility for his/her actions. Server selection involves client choices that affect client-perceived performance, hence the analogy. For more on Søren Kierkegaard, see The Stanford Encyclopedia of Philosophy.
