About Us
Mission
To create a predictable, and well-supported environment in which Internet2
campus network users have routinely successful experiences in
their development and use of advanced Internet applications
by focusing resources and efforts on improving performance problem
detection and resolution throughout campus, regional, and national
networking infrastructures.
E2Epi Overview
The E2Epi objective is to create a predictable and well-supported
environment in which Internet2 campus network users have routinely
successful experiences in their development and use of advanced
Internet applications by improving performance problem detection
and resolution throughout networking infrastructures. One project
of E2Epi is to establish a performance measurement infrastructure
across Internet2 campuses and labs, perform analysis of the
end-to-end path, and establish a normal operational mode where
network operations, applications, and the end-user easily can
determine network capabilities and restrictions. In addition,
the E2Epi is developing systems for gathering and disseminating
information such as campus best practice guides, troubleshooting
tips, and known problems and solutions. A collection of case studies can be found here.
History of the E2Epi
One of the originating premises for Internet2 is that Quality
of Service (QoS) will solve reliability problems experienced through
the commercial internet. It was presumed that, in the absence
of QoS, bandwidth overload would solve problems. Eventually, there
came a realization that bandwidth alone can’t solve all
problems -- Matt Mathis of PSC posits a "Wizard Gap":
those with technical know-how can nearly always use a system to
full (or near full) potential while the average user is experiencing
end-to-end problems or an insignificant increase in speed. This
document is an indepth history, chronologically presented
month-by-month from inception, detailing the development of the
Initiative, including links to documents prepared and presentations
made by members of the team at various conferences, workshops,
and small group meetings.
