Verizon touts smart P2P software

Slashdot It! A real-world Internet test reveals that "intelligent" routing of peer-to-peer traffic can drastically reduce network utilization and speed up downloads for subscribers, according to a new study. Verizon Communications, which participated in the study headed by researchers at Yale University, plans to release the data on Friday at the Distributed Computing Industry Association's P2P Market Conference in New York City. Using network topology data from Verizon and Telefonica, Yale University tested a software enhancement to the peer-to-peer protocol that it developed with software developer Pando Networks. What the researchers discovered was that when using the so-called P4P software they were able to reduce the impact of peer-to-peer traffic on Verizon's network by more than 50 percent. This is significant because peer-to-peer traffic makes up roughly half of all traffic traveling over Verizon's network. The P2P protocol, which is used to distribute large data files, works by requesting pieces of a single file from different hosts all over the Internet. The technology has become popular for distributing high-definition video. But applications that use P2P eat up a lot of bandwidth, which some service providers say is a problem. Cable operator Comcast has slowed down certain kinds of peer-to-peer traffic in an effort to manage its network. And Time Warner Cable is experimenting with a tiered usage model to deter people from sharing P2P files.
