Verizon comes up with P4P, double the fun of P2P?

The Distributed Computing Industry Association’s P4P workgroup is devising a new protocol for what researchers describe as carrier-grade peer-to-peer file transfer systems. Verizon reports that a recent test it conducted revealed that the new protocol provides a significant boost in download performance while simultaneously reducing network congestion.

P4P, which stands for Proactive network Provider Participation for P2P, ultimately aims to decrease backbone traffic and bring down network operation costs by enabling service providers to communicate information about network conditions to client applications for the purpose of facilitating improved P2P file transfer performance. Instead of selecting peers at random, the P4P protocol leverages network topology data so that peers can be selected in a manner that increases routing efficiency. (link)
