Two P2P Networking Approaches

Abstract:

"Peer-to-Peer" is a very hot topic today. Two papers at
SIGCOMM 2001 presented approaches to efficiently locating a
file based on its name (or some other attribute):

  "Chord: A Scalable Peer-to-Peer Lookup Service for
  Internet Applications", by Ion Stoica et al

  "A Scalable Content-Addressable Network", by Sylvia
  Ratnasamy et al.

The two approaches have striking similarities, yet differ in
the way that they scale.  I will summarize the approaches
and their similarities and differences, in the hope of
sparking some discussion of P2P and its utility (or lack
thereof).
