AT&T, Comcast, and Verizon See Increased Delivery Speeds and Improved Network Efficiencies

We look forward to continuing our cooperative relationships with industry and academic partners, working together to find effective solutions for users and networks operators, and supporting their adoption.

Pando Networks, a leading provider of content delivery services that accelerate the speed and dramatically decrease the cost of distributing rich media online, today announced results of a second round of P4P field trials.

P4P refers to an advanced technology for accelerating peer-to-peer (P2P) distribution of content and optimizing utilization of Internet service provider (ISP) network resources in order to provide the best possible performance to end-user customers.

Major ISPs including AT&T, Comcast, and Verizon Communications participated in the field trials coordinated by Pando Networks and Yale University during Fall 2008 as an activity of the P4P Working Group (P4PWG), a multi-industry initiative sponsored by the Distributed Computing Industry Association (DCIA).

The new trials built on the success of the first field tests conducted in Spring 2008 by Pando and Yale with two telco operators: Verizon and Telefonica Group. Comcast, participating in the second round, is the first cable operator to test P4P.

As part of this second round of P4P field trials, more than one million consumers worldwide downloaded a video program delivered by Pando Networks using different P2P algorithms including standard P2P delivery and P4P, a mechanism that allows ISPs to provide guidance to P2P applications.

The results demonstrated improved performance for all classes of users for all participating ISPs, using cable, digital-subscriber-line (DSL), and fiber-to-the-home (FTTH). Download delivery speed increased on average fifty-nine percent (59%) - and up to one-hundred-fifty percent (150%) for the fastest class of users.

The second round of P4P field trials also showed improvements in how the P4P protocol can increase P2P efficiency for broadband network operators by delivering data to end-users from within their networks as opposed to pulling data from external sources.

The percentage of data delivered within each ISP increased from fourteen percent (14%) for normal P2P delivery to as much as eighty-nine percent (89%) for P4P delivery.

In addition, a majority (up to 60%) of the internal data delivered using P4P was delivered within the same metro area. This decreases the distance data travels across an ISP network, thus increasing delivery speeds while decreasing overall network operating costs.

Pando Networks CTO and P4PWG Co-Chair Laird Popkin said, "This round of trials also introduced a new capability of P4P, extending the protocol to optimize traffic among ISPs. This allows ISPs, for example, to direct P2P applications to use private ISP-to-ISP connections instead of expensive transit across the general Internet, further improving delivery performance and reducing delivery cost."

DCIA CEO Marty Lafferty added, "The improvement in results achieved by Pando Networks, Yale University, and a larger number of participating ISPs in this second round of P4P field trials further validates the potential value of P4P. The technology has now demonstrated tremendous benefits for cable as well as telco-based ISPs. We are excited to be moving ahead with its further development and look forward to its ultimate deployment."

Commenting on the release of the results, executives from industry-leading ISPs indicated support for the initiative and a willingness to participate in more testing.

"The trial results demonstrate that P4P has the potential to increase network efficiencies, which ultimately could provide Internet users with a better and faster broadband experience," said Charles Kalmanek, Vice President - Networking and Services Research, AT&T Labs. "We look forward to continuing our cooperative relationships with industry and academic partners, working together to find effective solutions for users and networks operators, and supporting their adoption."

"Comcast believes that collaboration and engagement with the Internet community, engineers, academics and other experts is the best way to evaluate new Internet technologies like P4P," said Barry Tishgart, VP of Internet Services for Comcast. "We're encouraged by the results of the first P4P trial recently conducted on our cable ISP infrastructure, and we look forward to participating in additional P4P trials as we continue to optimize our network to provide the best experience for all customers."

According to Verizon Senior Technologist Doug Pasko, Co-Chair of the P4PWG, "In this second round of P4P trials, route guidance reduced the P2P traffic entering Verizon's networks from a previous average reduction of thirty-five percent (35%) to a reduction of more than seventy-five percent (75%). P2P traffic leaving Verizon's networks was reduced from an average of forty-one percent (41%) to fifty-four percent (54%). This again illustrates how ISPs can operate more efficiently if traffic remains on their own networks."

"The P4P field trials have repeatedly proven that localized P2P delivery is a 'win-win' for consumers, content owners and broadband network operators," added Robert Levitan, CEO of Pando Networks. "Pando Networks is proud to offer P4P functionality as a part of our content delivery cloud solution."

About the P4P Working Group

The P4P Working Group (P4PWG) was established in July 2007 under the auspices of the Distributed Computing Industry Association (http://www.DCIA.info).

The P4PWG's mission is to assist Internet service providers (ISPs) and peer-to-peer (P2P) software distributors in accelerating content distribution and optimizing network resource utilization to provide the best possible performance for end-user customers.

It is co-chaired by Doug Pasko (Verizon Communications) and Laird Popkin (Pando Networks).

Active participants include Abacast, AHT International, Alcatel-Lucent, Allsii, Andolis, Arrisi, AT&T, Bell Labs, BitTorrent, Bezeq International, Camiant, China Mobile, Cisco Systems, CloudShield, Comcast, Conviva, Digimeld, Digital Containers, Dow Lohnes, France Telecom, Fujin Technologies, GridNetworks, Huawei, Immedia Semiconductor, Itiva, Joost, Juniper Networks, Kontiki, Level 3 Communications, LimeWire, LiveStation, Manatt, mBit, Microsoft, Nokia, Orange, Oversi, Pavlov Media, PeerApp, PeeringPortal, PPLive, Qwest, RawFlow, Solid State Networks, Sprint, Telecom Italia, Telefonica Group, Telstra, Thomson, University of Toronto, Velocix, VeriSign, Vuze, University of Washington, Yahoo, and Yale University Laboratory of Networked Systems (LANS). There are a similar number of P4PWG observers.
