Can ISPs and P2P Users Cooperate for Improved Performance?

Vinay Aggarwal, Anja Feldmann (German Telecom Laboratories)

Christian Scheideler (TU, Munchen)

ACM SIGCOMM Computer Communication Review


Problem: file content available within the querying node’s ISP is downloaded

from a node outside the ISP







  • Benefits: procedure

  • P2P users: improved query and file transfer performance

  • 2. ISPs: decreased cost of inter-ISP traffic and improved fairness


Implementation: procedure

Set of replicated servers within each ISP

or

Web Service



Simulations procedure

Impact of the oracle:

1) on network graph properties

2) on a real P2P file sharing system

Simulations are based on current ISP topology (derived from BGP routing information)



Impact of oracle on real P2P file sharing system procedure

Gnutella protocol was modified to use oracle service
