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

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

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

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

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

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

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

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)

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

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

Measurement Gap How the engineers see the network:

Measurement Gap How the users see the network:

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

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

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

Anticipated Partners  Campuses  Faculty and discipline communities  GigaPoPs  International partners  NSF-sponsored engineering efforts NLANR, Web100 Project,  Internet2 corporate members  Federal labs and agencies

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, …

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

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
