End to End Performance Initiative
Context for E2E Performance
High performance backbones are 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.
Advanced Applications
Distributed computation
Virtual laboratories
Digital libraries
Distributed learning
Digital video
Tele-immersion
All of the above in combination
Anatomy and Surgery Workbench and Local NGI Testbed Network
Allows students to learn anatomy and practice surgical techniques using 3-D workstations Network test bed evaluates the effectiveness of workbench applications

First Step
Workshop in Ann Arbor on 9 January, 2001
• 40+ participants• Each participant provided a short paper on “What does E2EPerformance Mean?”
• Planned agenda was not used in order to respond to more pressing issues from participants.
• Design team formed to create an overall vision paper.
Summary of Discussion
Input focused on both technical and human factors:
• Developing people infrastructure to support performance initiatives
• Managing communications and managing expectations
• Developing the measurement architecture, analysis standards and deploying them consistently
• Creating clearer definitions of “performance”
Areas of the Initiative
Applications
Host/OS Tuning
Measurement Infrastructure
Performance Improvement Environment (PIE)
Operations and Human Communications
Performance Evaluation and Review Framework (PERF)
Applications
•Work with specific application communities to help solve their performance problems.
•Use a few key, general purpose applications for performance testing.
Host/OS Tuning
•Provide Best Practices for getting the most from your computer.
•Locate or build tools for Host/OS performance diagnostics.
•Work with computer vendors on Internet2 Performance Packages.
Measurement Infrastructure
•Bring together current measurement efforts and projects in the community.
•Establish an End-to-End Measurement Infrastructure from the intersection of these works.
•Create diagnostic tools to determine the health of the network and locate performance problems.
Operations and Human Communications
Establish communications among common interest groups
• System administrators• LAN administrators• Campus NOCs• GigaPoP• Application support staff
Establish communications between groups for operations and problem resolution.
Performance Improvement Environment (PIE)
•Develop a dynamic environment where collaboration and information sharing will happen.
•Identify, collect and disseminate appropriate information for end-to-end related information.
•Include success stories,measurement statistics, reference materials, measurement tool documentation.
•Include pointers to materials already developed by other communities.
Performance Evaluation and Review Framework (PERF)
Establish a framework for resolving performance problems
• Provide known solutions by using the PIE• Tap community knowledge by facilitating group communications
• Coordinate a team of experts to solve hard problems
Internet2 Organization Role
Staffing• Cheryl Munn-Fremon, Initiative Director• Russ Hobby, Technical Architect• George Brett, Information Architect• Lisa Wilberding, Communications Coordinator• Terri Saarinen, Program Assistant
Internet2 Organization Role cont’d.
Funding• Facilitate seeking sources of funding• Internet2 will invest about $1.5 million per year
Communications coordination• Web site• Workshops, meeting presentations, …
E2E Performance Improvement Environment (pie)
•Performance Improvement Environment• aka The Knowledge Base• a repository • a collaboratory • living and archival documents • connections to other resources
E2Epie – Background
• E2E Design Team White Paper:• Called for “A web-based information system / knowledgebase… to function as a distributed document and resource repository.”
• Elements should include: documentation, training materials, information resources, downloadable tools, mechanisms for discussion groups, links to related resources, contact information
E2Epie – Background (continued)
• E2Epie principles and guidelines:• Provide active leadership and facilitation.• Build trust.• Create an economics of recognition.• Leverage existing resources.• Think big and start small.
• Major components• People to people (directories & collaboration space)• People to content (directories of projects & tools, Case
studies)• Problems to solutions (knowledgebase, expertise
connection)
E2Epie – Current Status
• Developing web site content to reflect recommendations of the Design Team and Consultant documents.
• http://www.internet2.edu/e2epi/
• Actively looking for supporting materials and resources to include in web site.
• Mail to: [email protected]
E2Epie – next steps
• Begin collecting stories.• Using interviews and other channels we will begin collecting
stories about performance improvement issues.
• We will work with EDUCAUSE Effective Practices and Solutions database for publishing the E2Epi stories.
• Identify and collect information about projects, resources, and tools.
• With help of Technical Advisory Group and other E2Epi participants we will make sure to have up-to-date and correct information.
• Explore resources and tools for collaboration efforts.• Discussion forum: http://e2edev.internet2.edu/discus/
Specific Action Examples
Establish repositories for ‘Best Practices’, ‘War Stories’, and tools
Deploy broad measurement capability
Build client performance assessment tools
Implement reference sites for interesting applications
Establish a working relationship with specific applications communities and disciplines
Develop online collaboration environments
