2 P2P File Sharing and Online Music Services Technology Task Force Joint Committee of Higher Education and the Entertainment Industry

3 Joint Committee Graham Spanier, President, Pennsylvania State University John L. Hennessy, President, Stanford University Charles Phelps, Provost, University of Rochester Dorothy K. Robinson, Vice President and General Counsel, Yale University Molly Corbett Broad, President, University of North Carolina Cary Sherman, President, Recording Industry Association of America Jack Valenti, President and CEO, Motion Picture Association of America Roger Ames, Chairman and CEO, Warner Music Group Sherry Lansing, Chairman, Paramount Pictures Matthew T. Gerson, Senior VP, Government Relations, Vivendi-Universal Irwin Robinson, Chairman, National Music Publishers Association Chairman and CEO, Famous Music Three Task Forces in Legal issues and legislation Education Technology

4 Technology Task Force Charge – Educate the community on the technology issues and options related to the illegal distribution of content using P2P Activities RFI #1 – Controlling illegal file sharing RFI #2 – Legal, online content services Share information from pilot projects

5 RFI #1 Charge – Document the range of available products and services for the control of illegal file sharing using P2P RFI organized by 11 criteria 19 responses Reviewed and documented by committees

6 Criteria Network architecture Scalability Protocol identification Granularity of protocols Content identification Examination of network packets or file content Distribution systems Resilience of the technology to countermeasures Testing and installed base Competitive approaches Third-party components


8 Wide range of proposals Restrict bandwidth by location, time, … Restrict bandwidth by application Filter “announcements” of available content Filter copyrighted songs and movies Detect songs and movies on disk Detect applications on disk Monitor all activity on PC Automate processing of “cease and desist”

9 Institutional Choices Choice of application is up to institutions Culture and environment Business considerations Individual agreements with vendors Pilot projects In conjunction with efforts in Education Ethics Law

10 Present Implementations Recent surveys 66+% shape bandwidth Location, application, time, … “Top talkers” 89% use policy and education 100% comply with DMCA notices “Homegrown” implementations Block “announcements” of available content Prohibit servers in residence halls

11 Technology Challenges Hard to discriminate violations of law Very large numbers of cases Technology (and policy) issues of privacy Arms race Solutions will require education and policy in addition to technology!

12 Long Term Solutions? Legal, online content New services New business models Disruptive innovations RFI #2

13 Bandwidth Shaping for P2P at the University of Maryland, College Park Gerry Sneeringer IT Security Officer 35,000 Students 12,500 Faculty/Staff Over 300 buildings spread across 1500 acres

14 Network Connectivity 4 paths onto Campus Network –OC3 Primary ISP Interface –DS3 Backup ISP Interface –Gigabit MaX/I2 Interface –Gigabit USM Interface Backup ISP and USM links not heavily utilized

15 Residential Networking 12,000 Students with Ethernet Connectivity 76 Residential VLANs Networked since the mid-90’s Managed by Central IT Organization Funded by Resident Life Office Traditionally liberal usage policies

16 The Troubles Begin Late ’90s – Occasional FTP server – situations handled, case by case 2000-2001 – Rise of the P2P application: Downloads and Uploads from Resnet occasionally impact campus pipes… limit BW available to dorm networks

17 The Troubles Continue Astronomic growth of P2P pegs Resnet bandwidth at whatever cap happens to be in place Good Users impacted as well as P2P users Targeting Network Ports = Whack-a-mole Torches and Pitchforks in the hallways of Administration

18 PacketShaper to the Rescue Search for a solution that is application-aware Desire to prioritize lag sensitive applications, constrain applications that are swamping the network Solution needed to scale to handle huge volume Ongoing support for newly discovered applications

19 UM PacketShaper Deployment Two PacketShaper 8500-ISP Deploy one on each of two primary ISP routers Use policy routing to deflect all packets originating or destined for Resnet through PS Used initially in passive mode to learn about the nature of Resnet traffic

20 Network Diagram Campus ISP Router MAX Router ISP MAX PSPS

21 Setting Priorities Reserve bandwidth for HTTP Prioritize interactive traffic Lowest priority for P2P class traffic Further choke troublesome applications Impede outbound file sharing as much as possible

22 Impact Rejoicing from the Good Users Silence from the File Sharers DMCA Complaints continue Extra point of failure on ISP connections Learning Curve

23 Freshman Orientation: Information Literacy Component West Virginia Wesleyan College Karen R. Petitto

24 WVWC Profile 1500 Students 85 Full Time Faculty Ubiquitous Computing Environment 1:1 Student to Computer Ratio Wired and Wireless Access

25 Direct Student Exposure First Exposure ThinkPad Orientation What You Need to Know About File Sharing and Downloading Distribute, Read Aloud, Collect


27 Student Acceptance Form

28 Direct Student Exposure Second Exposure Freshman Orientation 15-20 students per class 50 minute introduction to Information Literacy Information Literacy as defined by the Association of College and Research Librarians. _and_Advocacy1/Information_Literacy1/Information_Litera cy.htm _and_Advocacy1/Information_Literacy1/Information_Litera cy.htm Computer Care and Handling File Sharing/Copyright Information

29 Direct Exposure to Copyright Information Third Exposure Online Technology Training Required WebCT module that includes case study and specific campus information on bandwidth priority, P2P software, and Copyright Legislation





34 What is a Litigious World? It’s a reality.

35 An Information Literate Person Understands when information is needed Knows how to access information Can search effectively Can evaluate information Can use information in project/paper/speech Understands the legal and ethical issues of information in society
