ACM SIGCOMM Computer Communication Review


Can isps and p2p users cooperate for improved performance

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

from a node outside the ISP


Can isps and p2p users cooperate for improved performance

Reason: P2P networks employ arbitrary peer selection procedure


Can isps and p2p users cooperate for improved performance

Solution: Oracle Service


Can isps and p2p users cooperate for improved performance

Solution: Oracle Service


Can isps and p2p users cooperate for improved performance

Solution: Oracle Service


Can isps and p2p users cooperate for improved performance

Solution: Oracle Service


Can isps and p2p users cooperate for improved performance

  • Benefits:

  • P2P users: improved query and file transfer performance

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


Can isps and p2p users cooperate for improved performance

Implementation:

Set of replicated servers within each ISP

or

Web Service


Can isps and p2p users cooperate for improved performance

Evaluation Metrics


Can isps and p2p users cooperate for improved performance

Simulations

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)


Can isps and p2p users cooperate for improved performance

Impact of oracle on network graph properties


Can isps and p2p users cooperate for improved performance

Impact of oracle on real P2P file sharing system

Gnutella protocol was modified to use oracle service


Can isps and p2p users cooperate for improved performance
