Wired News: Toe-to-Toe Over Peer-to-Peer

According to Wired News, several ‘for-pay’ peer-to-peer networks are set to launch in the near future, though the question remains whether anyone will use these services as opposed to their free brethren. It seems that these companies are a victim of the capitalist system they love so much; people are choosing the lowest price, which happens to be free.

Peer-to-peer traffic has not declined despite the music industry’s aggressive pursuit of illegal file sharers, according to a new study.

Researchers from the University of California at Riverside and the Cooperative Association for Internet Data Analysis evaluated packet data on the internet and found that P2P continues to thrive. Their results are published in a study, titled “Is P2P dying or just hiding?”

“In general we observe that P2P activity has not diminished,” says the study, which will be presented at IEEE Globecom 2004 next month. “On the contrary, P2P traffic represents a significant amount of internet traffic and is likely to continue to grow in the future, RIAA behavior notwithstanding.”

The Recording Industry Association of America has sued thousands of individuals since September 2003 for allegedly using peer-to-peer services to share copyright music. The music trade group believes that cracking down on swappers who use P2P will serve as a deterrent to illegal file trading and provide a better environment for paid music services like iTunes, Napster and Rhapsody to flourish.

Previous studies reported that music downloading dropped as much as 50 percent after the RIAA started suing individual file traders. The researchers said claims that peer-to-peer is on the decline are inaccurate.

“We wanted to examine the truthfulness of reports claiming declining P2P traffic and help the community make reliable assumptions concerning P2P traffic estimates and trends,” wrote Thomas Karagiannis, a doctoral candidate in computer science at UC-Riverside, in an e-mail. “The assertion of declining P2P traffic was in direct contrast to the constant increase of P2P activity over the last year and counterintuitive to the fact that P2P applications are still the top most downloaded applications (on) the internet.”

The study recorded internet traffic through major internet service providers from August 2002 to January 2004. The researchers examined the packet data transferred through these links to determine what percentage of the total traffic was P2P traffic.

The researchers said their study is more comprehensive than previous ones because it measured more peer-to-peer protocols on the net rather than concentrating on well-known applications like Kazaa and Gnutella.

“We measure the traffic in a more intelligent way,” said Michalis Faloutsos, a computer science professor at UC-Riverside. “P2P traffic is making an effort to hide, and we are trying to go one step further and identify the hiding tricks and see if we can provide a more accurate estimate of P2P traffic on the net right now.”

The RIAA declined to comment on the study.

“They’ve done an enormous amount of work here and it’s clearly an important contribution,” said Jonathan Zittrain, co-founder of the Berkman Center for Internet and Society at Harvard Law School.

Zittrain said that one unanswered question for him is how the researchers account for interdiction. Music companies use interdiction to fill up the peer-to-peer queues with traffic in order to deny access to other users. He said that this technique could represent a significant amount of bandwidth.

Eric Garland, CEO of BigChampagne, which monitors file-sharing services, said the study is a complement to BigChampagne’s efforts to measure P2P use.

“We look at the number of users and files. This (study) seeks to quantify the traffic — the volume in bits and bytes,” Garland said.

According to BigChampagne, 7 million people use peer-to-peer services, at any particular moment, globally. About half the traffic is from users in the United States.
