March 8, Spring Internet2 Meeting

2. A little bit of history... Last year (2000):
Go after Napster and ban its use because of
- liability for being a content provider or
- degraded network performance.
Not ban its use and wait…
Metallica suit and all those events...
universities respond:
Banning it (mainly b/c it clogs the network)
“Passively” Monitoring (and keeping tabs on top hogs…)
Blocking, Rate Limiting, Fair Usage Policy Implementations
Educating (on copyright law and impact.)
Not doing anything at all and waiting…
March 8, Spring Internet2 Meeting

3. Later in the year...
Internet2 Member Meeting (October 2000, Atlanta, GA) Taming the bandwidth hogs…how can your campus do it?
Creation of list to further discussion on issues brought up at BoF (listserv.utk.edu/archives/p2p.html)
News.com: a third of U.S. colleges and universities are blocking Napster
March 8, Spring Internet2 Meeting

4. What then, also now...
Napster is just one of a host of applications that can be used to transfer music and movies.
planning for constantly increasing bandwidth demand without increasing funding.
Some tools/techniques exist
"Educating" and involving students
Scarce resources and provisioning. How much? What is fair? How to implement?
P2P applications are changing our traditional paradigms.

5. Then, Feb. 2001 and just this week
9th Circuit Ruling (Feb. 14)
March 6: Napster has 72 hours to halt all illegal traffic in certain copyrighted material. The clock starts ticking once Napster has been provided with a list of copyrighted material to block the transfer of. The list will need to include the title of the song, the name of the artist, and the name of the file before Napster is required to block transfers of that file.
By March 11, 2001, Napster and the record companies; “shall use reasonable measures in identifying variations of the filename(s), or of the spelling of the titles or artists' names, of the works identified by plaintiffs.”
March 8, Spring Internet2 Meeting

6. Since then...
Aimster developers immediately produced a pig-latin encoder, further obscuring the limitations of Napster's filtering task. The encoder takes each of the file names of the mp3 files in your Napster directory and encodes the file names so that the name cannot be easily monitored.
Infoanarchy.org Wed Mar 7th, :24:12 PM: As announced yesterday, Matt Goyer of Fairtunes.com, a site that collects voluntary donations to artists, wants to set up an OpenNap server "beyond the reach of the RIAA". Specifically, his plans are to rent a server on Sealand, a swimming military fortress. If you think that the idea might make sense, you can donate here or PayPal the money to If not enough money is collected (minimum $15,000), Goyer says that "all funds will be returned to the contributors". Right now they're at a measly $ too bad the server was down yesterday, when all the net media reported about it. Now he'll have a hard time getting this in the press again.

10. Application/port filtering
“Blocking Napster is like standing before hundreds of hungry jackals and shouting “Shoo!” to keep them from 400 pounds of raw hamburger.” Chronicle, 9/21/00
“Punishing the traffic of one application, using the rough technology we currently have available, accelerates users migrating to new apps more difficult to identify.” Steve Wallace, IU. NLANR/I2 Techs meeting, Toronto, CA.

14. Provisioning
Should we provision our campus networks with p2p in mind? Or are we too late for that? Are we still on time?
What role can Gigapops and service providers play when adressing these issues?

15. Just make the pie bigger...
Economics, as you’d learn in the first five minutes of a good section of Econ 200, is the study of the allocation of scarce resources. ...the University’s technology administrators could certainly benefit from attending a few of those classes…
With a little creativity, Napster could even help foot the bill [for necessary upgrades] Since it is a popular program, presumably students will be willing to pay something to use it. While all students get a free Internet account, the University could charge a premium if they want a “high volume” account.
The solution to this problem of scarce resources is to figure out how to make the pie bigger, not to take away student’s dessert.

16. Another perspective: Napster in other countries
you don’t want it, we will take it.

17. A survival model for the music industry
p2p brought up the antiquity and "out of touch" Internet business strategy of the recording industry.
new business models will need to be developed and implemented, with a revised, if not very different, modern notion of copyright and intellectual property.
With the current "search and destroy strategy" the music industry will only enhance the conflict between artists, online players, and music listeners; "The music industry will forfeit its central mediator role."
"Napster, only online for 12 months, already posseses a better brand name than the established record labels, and [is] thus meeting with widespread acceptance from the online community. 14,000 songs are exchanged via Napster per MINUTE - no record label has anything comparable to counter this.”
