Internet2 & the SC Community
Internet2 believes the work of your
community is one of the primary
applications drivers for our work
• We welcome the challenge of supporting the needs of
your advanced applications
• We want to make your capabilities available to scholars
here and elsewhere across the world
The Internet2 Foci
 Advanced Applications Development
• Ted Hanss
 Advanced Network Infrastructure
• Guy Almes & Matt Zekauskas
 Middleware Infrastructure for Higher Education
and Research
• Ted Hanss & Micah Beck
 New Networking Capabilities
• Guy Almes & Ben Teitelbaum
 Technology Transfer
 Partnership and Awareness
Applications
Different Disciplines/Contexts
Sciences
Arts
Humanities
Health care
Business/Law
Administration
…
Instruction
Collaboration
Streaming video
Distributed
computation
Data mining
Virtual reality

…
Application Attributes
Interactive
research,
collaboration, and
instruction
Real-time access
to remote
resources
Attributes, cont.
Large-scale, multisite computation
and database
processing
Shared virtual
reality
Any combination
of the above
Campus & Discipline Outreach
Internet2 Days
Talks and demos at discipline
conferences
Working jointly with NLANR
• dast.nlanr.net
I2 Middleware Initiative:
The “Services Rich”
Network Environment
Or
“From Circuits to Services”
What’s an Ideal “Internet2”
Functional services available to
users and developers
• Enabling new collaborations and applications
• Supported as production quality
• An integrated framework
Scaled to the size of the research
and education community
The Core
Identifiers for people, objects,
groups
Authentication for people, objects
and groups
Directories to store common
information
Applications that use all of the
above
I2 Middleware Activities
Early Harvest “Techshop”
Early Adopters
Measurements in Internet2

SC99
Portland, OR
November, 1999
‘My application has a problem’
Where is it?
Network? Host (stack,config)? Application?
Local passive measurements can
help localize the problem
Consistent measurement throughout
Internet2 infrastructure can help
diagnose network problems (and
also help localize the problem)
Other Measurement Goals
Network engineering
Network research
Feedback to applications
Operational data
• performance, flows, anomalies
Network characterization
• how used? load response? SLS?
Today
All: at least SNMP statistics
Backbones: (vBNS, Abilene)
publishing
• http://www.vbns.net/
• http://www.abilene.iu.edu/
Various uncoordinated activity
Today
Active measurement efforts:
AMP (NLANR/MOAT),
Surveyor (Advanced), {PingER}
• http://moat.nlanr.net/AMP/
• http://www.advanced.org/surveyor/
Passive measurement effort:
NAI (OCXmon) (NLANR/MOAT)
• http://moat.nlanr.net/
Delay Between Two East-Coast Tele-Immersion Sites
Working Group Activities
Measurement architecture
Encourage common
• Measurements, tools
• Parameters
• Reporting
Work with (at least) network
management, QoS, multicast
working groups
Ideal
Consistent measurement of
• Utilization
• Performance
• Traffic Characterization
With generally available results
Combined with “well known”
measurement targets/observatories
for on-demand tests
Also
Want some way to know where loss
occurs when it happens (or delay)
Advanced service debugging
• Multicast
• QoS (QBone designing measurement in),
additional E-E service verification?
Reporting
All measurements available via Web
Site/Router-relative URLs
• allows computed URL
I2-Wide measurements page to allow
for browsing
Need to be cognizant of security &
privacy issues
• mainly passive measurements
On the Horizon: TAAD
Traffic Analysis and Auto Diagnosis
• Developed by Matt Mathis and
Kathy Benninger at NLANR ES
• Works on data collected by OCXmon (passive)
• Automatically diagnose specific types of TCP/IP
performance problems
• Network limited flows
• Mis-tuned application or TCP stack
• When complete, available at:
http://www.ncne.nlanr.net/TCP
Summary
Consistent measurement of
• Utilization
• Performance
• Traffic Characterization
That are made generally available
Plus targets/observatories
In support of applications and the
networks themselves
