Resource allocation strategies for scalable content delivery on the

George Smaragdakis


The Internet architecture was not originally designed to facilitate
scalable content distribution. As a result, the explosive growth of
Internet content distribution overlays and applications posed new
challenges to overlay network design and maintenance, involving many
entities with different perspectives and possibly conflicting objectives
-- namely content producers, consumers, and distributors. In this
presentation, I will survey methodologies that have been developed to
facilitate scalable content distribution from these three perspectives. 

To that end, I will present a taxonomy that classifies the approaches
taken along three dimensions: (1) The resources allocated by entities to
facilitate content distribution, namely storage and connectivity; (2)
The scope of the optimization process underscoring the allocation of
resources, namely greedy, strategic, and altruistic; and (3) The degree
of knowledge assumed about the setting, namely whether it is global or
partial. Along these lines, I will review the key literature in content
replication and caching, as well as in peer-to-peer network formation,
highlighting promising game-theoretic-inspired approaches that better
model the interaction between different entities.
