On the Many Facets of Neighbor Selection for Overlay Networks
Monday, December 10, 2007
12:00 p.m. - 1:00 p.m.
366 West Village H
Northeastern University
Abstract:
A foundational issue underlying many overlay network applications is that of connectivity management, i.e., how to fold new arrivals into an existing overlay, or re-wire to cope with changing network conditions and node churn. In this talk I will try to outline the design space of neighbor selection strategies by looking at specific instances drawn from different applications like overlay routing, P2P file sharing, and broadcast systems. These applications give rise to different flavors of the neighbor selection problem, which differ in multiple aspects including the scope of communication (1-to-1, 1-to-many, many-to-many), the available information (local or global), the utility mode (selfish or cooperative), and the deciding entity (either the node or th
network itself). This rich family of problems carries with it several new research challenges and opportunities for improving the performance of existing simplistic random and greedy local strategies without sacrificing their practicality.
