Internet2 Campus Workshop
Atlanta, Georgia
The Problem
Even with high bandwidth network
links, the Internet2 community
often does not see expected
performance.
Internet2 Campus Workshop (May 30, 2001)

E2E Perf Initiative Vision
To enable the end-user to obtain
optimal performance from the
available current and future
infrastructure on a routine basis.

The Initiative is
A Coordinating Structure
• Will not replace current activities in the area
• Will encourage work where there are missing activities
• Coordinate activities to support E2E Performance
• Help to move developments into operation
A Communications Facilitator
• Promote communications for common areas
• Tools for cross-area communications
A Knowledge Repository
• Collect and disseminate knowledge gained
• Distribute tools developed
Internet2 Campus Workshop (May 30, 2001)

Participants
The Initiative is Structured Around
Partnerships among
• Applications Communities
• Network Operators
• Gigapops
• Network Researchers
• Campuses
• Corporate partners
• Internet2 Staff

Applications Communities
They are the reason to have the network!
The Initiative will:
• Work closely with selected test communities
• Focus on helping them do what they want to do
• Use their key applications to evaluate and improve
network performance
Internet2 Campus Workshop (May 30, 2001)

Campuses include the
“Ends” in End-to-End
Campus concerns include:
Campus Users - overall performance and
end result of the application.
System Administrators - computer hardware
and operating system.
Network Operators - performance of the
network.

• Common Data Sets Collected
• Applications Reference Servers
• Download of Special Testing Software
Develop Analysis Tools
• Study Network Behavior
• Pinpoint Source of Problems
• Determine the Health of the Network
Internet2 Campus Workshop (May 30, 2001)
15
Operational Support
Develop a Coordination and Communication
Structure for Support Personnel Groups
• Computer System Administrators, LAN Managers,
Campus NOCs
• Access to Experts
• Cross-Campus Support
Establish the Performance Evaluation and Review
Framework (PERF)
• A Coordination Structure to Study and Resolve Hard
Problems
• Help populate the Knowledgebase of Solutions
Internet2 Campus Workshop (May 30, 2001)
16
Operational Support
Other Operational Developments
• Knowledgebase creation and use
• Cross-Domain Trouble Ticket System for use by
NOCs (initially) and End-Users (later)
• Standard Sets of Operational Data that
everyone can use to determine network
capabilities and limitations.

Show Me the Money
UCAID has committed ~$1.5 million in
project funding to provide central
coordination and support
Initiative coordination activities include
proactively identifying potential funding
sources and developing funding
opportunities
Potential funding agencies have
participated in the planning stages and
discussions will continue
Internet2 Campus Workshop (May 30, 2001)
19
Next Steps
White paper still open for comments
Design Team work continues
Produce an action plan and post
Develop the Calls for Participation
Specify review process
Issue first set of CFPs, and begin work in
specific areas
Form an advisory and management
structures
