Internet2 Applications
What are “I2 applications”?
They deliver qualitative and
quantitative improvements in how we
conduct research and engage in
teaching and learning
They require advanced networks
to work

Advanced Internet Benefits
Richer content through higher
bandwidth
• Video, audio
• Virtual reality
• Dynamic not static
More interactivity via minimal delay
Reliable content delivery through
quality of service model
Engaging Developers
Outreach
• Go to the faculty on campus and at
discipline meetings
• See apps.internet2.edu/i2-day.html
Educating about development issues
• Portability, interoperability, scaling, ...
• Multicast, QoS, security, …
• E.g., see dast.nlanr.net/
Middleware Challenges
Identify technologies that are
scalable, interoperable, and with
standard APIs
Increase deployment of middleware
technologies as part of a production
environment
Applications:
Horizontal, Vertical, Spot Solutions
Standard APIs
Middleware:
Security, Directory, Quality of Service,
Audio/Video Frameworks, Accounting,
Collaboration Frameworks, Multicast
Standard APIs
Operating system and network services
Interoperable Protocols
Content Opportunities
Licensed educational materials
Copyright-expired audio/video works
Sensor data
Financial data
“Work in process” lectures shared
between schools
Engineering
Engineering Objectives
Deploy a production network for
applications R&D
Establish quality of service (QoS)
• Allow applications to request and receive
performance attributes
Objectives, cont.
Support native multicast
• Deliver lots of information efficiently to
lots of people
Establish GigaPoPs as effective
service points

“Gigabit capacity point of presence” an
aggregation point for regional connectivity
Interconnect
Today we use the vBNS (very high
speed backbone network service)
• Five year (1995-2000) cooperative
agreement between the NSF and MCI
• Currently operating at OC12 (622 mbps)
The vBNS peers with other federally
sponsored networks
Will be joined by Abilene Network
GigaPoPs
Variety of services and styles
• Technical and organizational differences
• Mixture of technologies
Some things must be the same
• IP as common bearer service
• Inter-GigaPoP routing policy and design
• Measurement
• Trouble tickets among network
operations centers
