After achieving much faster than usual download and data delivery rates in a field trial with Verizon and Pando, the P4P Working Group is now looking at doing trials with other ISPs and P2P network providers, said Haiyong Xie, a working group member who is also a Ph.D. student at Yale. In results unveiled today at DCIA’s P2P Market Conference in New York City, the P4P technology was shown to enhance download rates by 205 percent over unmanaged P2P downloads, and to decrease the number of hops needed in ISP internal data delivery from 5.5 hops to 0.89 hops.
The trial made use of Xie’s implementation of P4P networking principals, Pando’s application plattform, and network topology data from Verizon. Essentially, P4P is designed to speed up P2P downloads by localizing network traffic and reducing the numbers of routers and transfers needed for distributing data. In a traditional P2P network, if a Verizon customer downloads a file, only 6.3 percent of the data will come from another Verizon customer in the same city, said Doug Pasko, senior technologist at the company. In the “P4P” trial, 58 percent of the data came from nearby Verizon users, vastly reducing the company’s cost of carrying the traffic.
