I just submitted a new draft on why I think P2P edge caches are
necessary, and how localization interacts with edge-caches.
Among other things, edge-cache support requires associating filename
information with requests (and therefore has privacy implications), etc.
Abstract:
Without caches in the infrastructure, peer to peer content
delivery's
primary effect is cost shifting rather than cost savings. Even with
perfect localization, depending on the relative cost of last-mile
uplink bandwidth verses transport bandwidth, P2P may substantially
increase aggregate cost. Yet the addition of edge caches, caches
located in the ISPs near the customers, radically change the
economics of P2P content delivery. Edge caches interact very
strongly with localization services for P2P content delivery, and
any
localization service must be tightly integrated into edge-cache
operation.
Comments greatly appreciated.
