Verizon News : P2P Speed-Up Promised

While the likes of Comcast are trying to undermine peer-to-peer transfers, it appears that other are smarter and have thought of technologies to both speed up such file sharing transfers and minimize bandwidth consumption. Verizon has announced that it has been working with researchers at Yale University on new ways to enhance the peer-to-peer opportunity through faster downloads and lower costs for the ISPs.

Test results for the new technology will be presented by the company at the Distributed Computing Industry Association’s P2P conference in New York today by the association’s P4P division. "This test signifies a turning point in the history of peer-to-peer technology and ISPs," said Robert Levitan, chief executive of P2P developer Pando Networks, the Associated Press reports.

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.

"Before doing this field trial, we'd conducted simulations. But results of the trial prove that P4P also works in the real world," said Laird Popkings of Pando Networks, co-chair of the P4P Working Group, speaking with BetaNews at the event in Manhattan.

A similar field trial is still under way with Pando -- a company which partners with NBC Direct, for example, on P2P content delivery -- and Spanish-based ISP Telefonica. Results from the Telefonica trial are expected over the next week or two.

"But different P2P networks have different properties, as do different ISPs," said Xie, during another interview with BetaNews at the event.

"We're also interested in seeing how the P4P technology works with other P2P networks and with other ISPs," according to the Yale researcher.
