Informed Content Delivery Across Adaptive Overlay Networks - 10/04/2002
Overlay networks have emerged as a powerful and highly flexible method
for delivering content. The paper studies how to optimize throughput of
large, multipoint transfers across richly connected overlay networks,
focusing on the question of what to put in each transmitted packet. It
provides a collection of useful algorithmic tools for efficient
estimation, summarization, and approximate reconciliation of sets of
symbols between pairs of collaborating peers, all of which keep
messaging complexity and computation to a minimum. Through simulations
and experiments on a prototype implementation, the performance benefits
of informed content delivery mechanisms and how they complement
existing overlay network architectures is demonstrated. Lab of Networking and Information Systems Room 413 Photonics Building 8 St Mary's Street, Boston MA 02215 Web site created by Sachin Agarwal (ska@bu.edu)
