Madrid (PRWEB) April 25, 2008

Telefonica International Wholesale Services, a leading global provider of international wholesale services, part of the Telefonica Group, today released data from its initial field test of advanced peer-to-peer (P2P) protocols, known as P4P, on Telefonica’s broadband network in Peru. The results show that the new P4P protocols increased network efficiency by shifting traffic from external to internal links and by routing the internal traffic shorter distances across the Telefonica network.

The amount of data delivered from internal versus external links increased by 268%. In addition, the data delivered across the internal Telefonica network was delivered across fewer network links, thus resulting in a reduced load on the network backbone. Specifically, with P4P protocols, the localized or “cross-metro” data delivery increased from 1% to 36%. The distance the data traveled, measured by metro hop count, decreased by 57% from 3.78 to 1.62.

Telefonica Wholesale is the first international broadband carrier to test P4P protocols in the field. The results on its network further confirm that P4P can provide significant network efficiencies for all Internet service providers (ISPs).

“We are very pleased with the positive indication of our initial P4P test results for global ISPs, with multi-domestic broadband operations, and unique requirements for optimizing internal and external traffic loading,” said Emilio Sepulveda, Senior Manager, Strategy & Business Innovation, Telefonica International Wholesale Services. “We look forward to expanding our tests to involve larger operations in Europe and elsewhere as the next phase of Telefonica’s participation in the P4P Working Group (P4PWG),” he added.

The technology used in the Telefonica P4P field test was based on research by Haiyong Xie et al from the Laboratory of Networked Systems (LANS) at Yale University. The experimental software was initially developed by Haiyong Xie and later by LANS and Pando Networks, and tested using network data provided by Telefonica Wholesale. The protocols and specifications are being shared among other ISPs and P2P companies within the P4PWG, sponsored by the Distributed Computing Industry Association (DCIA).

The P4PWG is Co-Chaired by Laird Popkin, Chief Technology Officer of Pando Networks, and Douglas Pasko, Verizon Communications Senior Technologist, and currently includes more than 60 participating companies including ISPs such as Telefonica, AT&T, and Comcast, and P2P providers such as BitTorrent, Kontiki, and Vuze.

Previous results of P4P field tests were presented March 14th in New York at the DCIA P2P MARKET CONFERENCE and released in a press announcement by Pando on April 9th.

DCIA CEO Marty Lafferty said, “Telefonica’s results in its initial P4P field test further underscore the worldwide potential for dramatic improvements in P2P efficiency and quality of service (QoS) for both large and small network operators.”

“The Pando engineers are thrilled to see our P4P implementation have such positive impact on an international broadband network with Telefonica,” said Popkin.

“P4P is a flexible framework for ISPs and P2P companies to work jointly to improve network performance,” said Haiyong Xie, Principal Researcher of P4PWG. “It is great to see the active involvement of Telefonica as the first international Tier-1 ISP in demonstrating the benefits of P4P.”

The impact of these advanced P2P technologies is wide ranging. P4P makes the Internet a more scalable media distribution platform while benefiting various online media constituencies. It helps ISPs reduce network operating expenditures as well as enabling content owners to distribute longer form, higher quality content.

“Telefonica showed great industry leadership with its early involvement in the P4P Working Group and by being the first international ISP to test P4P protocols,” said Robert Levitan, CEO of Pando Networks. “Pando is proud to work with companies such as Telefonica. Our work together can fulfill the vision of the Internet as the world’s most robust media distribution platform.”
