1. Internet2 End-to-End Performance Initiative or Why Fat Pipes aren’t Enough Ted Hanss Director, Applications Development 16 May 2001 See http://apps.internet2.edu/talks

2. The Vision Internet2 campus users have routinely successful experiences in their development and use of advanced networked applications.

3. The Vision Internet2 campus users have routinely successful experiences in their development and use of advanced networked applications. Circuits Applications Performance

4. Context for E2E Perf  High performance backbones in place  Now, under certain conditions within particular regional and local network environments, we can experience the full benefit of this infrastructure in the development and use of advanced applications

5. Context, cont.  However, most of us experience a significant gap between the reality and potential of the national high-performance networking infrastructure

6. Terminology Distinction  The phrase “End-to-End” has multiple meanings in several contexts End-to-End Architecture End-to-End Performance  Therefore, this initiative always will be referred as End-to-End Performance

7. True End-to-End Experience  User perception EYEBALL  Application APPLICATION  Operating system  Host IP stack STACK  Host network card  Local Area Network (LAN) JACK  Campus backbone network  Campus link to regional network/GigaPoP  GigaPoP link to Internet2 national backbones  International connections

8. Example  NASA/Jet Propulsion Laboratory analysis of performance-related complaints

9. Example  NASA/Jet Propulsion Laboratory analysis of performance-related complaints Over 60% were duplex mismatches

10. First Step  Workshop in Ann Arbor on 9 January 40+ participants Each participant provided a short paper on “What does E2EPerf Mean?” Charged a design team to create an overall vision paper (delivered in February)

11. Summary of Discussion  Input focused on both technical and human factors: Developing the people infrastructure and managing communication and expectations Developing the measurement architecture and deploying it consistently

12. Overall Approach  Education and outreach  Applications enhancement  Performance measurement infrastructure  Operations coordination  Campus upgrades  Many partners Filling the gaps in the union of existing efforts

13. Measurement Gap How the engineers see the network:

14. Measurement Gap How the users see the network:

15. Specific Action Examples  Identify network and applications teams  Develop integrated and distributed operational support Performance Evaluation and Review Framework  Establish repositories for ‘Best Practices’, ‘War Stories’, and tools  Implement reference sites for interesting applications

16. Action Examples, cont.  Deploy broad measurement and analysis capability Active and passive measurement Ongoing baseline measures Diagnostic tools Protected from use as an attack platform

17. Applications Measurement  An idea: Create the disambiguator (also known as “the finger pointing tool”) No one is able to obtain the complete picture of any end-to-end path Deploy 1000 autoconfiguring “shoebox” size PCs at every level, including the faculty member’s office Allow testing at and between points on the network

18. Anticipated Partners  Campuses  Faculty and discipline communities  GigaPoPs  International partners  NSF-sponsored engineering efforts NLANR, www.nlanr.net Web100 Project, www.web100.org  Internet2 corporate members  Federal labs and agencies

19. Internet2 Organization Role  Staffing Cheryl Munn-Fremon hired as initiative director, starting in June  Funding Facilitate seeking sources of funding Internet2 will invest about US$1.5 million  Communications coordination Web site Workshops, meeting presentations, …

20. Call For Participation  Identify core applications and services Portfolio of base applications 4-6 application communities Criteria – Both UDP and TCP-based apps – Exploit advanced services – At least one international collaboration  Seek participants in the various work areas  Issued this summer

21. Success Criteria  Solutions scaled to a diversity of institution sizes and resource capabilities  Application users and supporters interested and involved  Applications use is routine and spontaneous without a reliance on experts  End-users understand what to expect and how to get it Wizards
