Internet2 Network
• Dedicated point-to-point wavelength services• Dynamic Circuit Service
• Point-to-point Ethernet (VLAN) Framed SONET Circuit• Point-to-point SONET Circuit• Bandwidth provisioning available in 50 Mbps increments
• Best-effort high-speed IP Service• Enables delivery of advanced content, commodity services,
etc.• Physical Connection
• 1 or 10 Gigabit Ethernet• OC-192 SONET
Flexible Infrastructure Supporting e-Science, Network Research & Education
Slide 8
Internet2 Network
• Connection Oriented Services provide for:• Guaranteed bandwidth (predictable, repeatable, dependable
performance between collaborating sites)• Traffic segregation (support specific policy or traffic engineering
requirements)• Router bypass: Express links created for high-bandwidth, limited
duration long-haul traffic reducing the need for mid-path L3 interfaces• Cost efficiency: L3 router blades cost > L2 ports > L1 or L0 interfaces• Capability tradeoff but could possibly improve performance
• Automated dynamic circuit services enable rapid provisioning and efficient utilization of capital investment• Establishing end-to-end lightpaths is a non-trivial task: it is resource
intensive and error prone • Automated reservation, allocation, and provisioning enables co-
scheduling of network and non-network resources.

Slide 10
Internet2 Network
• Create private networks between key collaborating sites within a science community or on a project-by-project basis. Examples:• Radio Astronomy community sharing telescopes and
correlation facilities• High Energy Physics community distributing large data sets• Smaller projects may link data repositories and computational
resources among key participants – e.g. grid portals• Network engineering and operations community can use
these capabilities to support traffic engineering objectives• We expect applications will use these circuit services
to carry high-bandwidth, limited duration flows and will retain use of IP links for generic Internet access.

Collaborations
• The DICE group - Dante (GEANT2), Internet2, CANARIE, and ESnet• Working closely with ESnet on interfacing OSCARS and
HOPI - involves AAA work, using OSCARS interface• “Stitching” project to describe data layer interconnections
between segments of a PTP path• Reporting back progress to the GLIF and other
organizations• For example, Phosphorus, in coordination with the SURFnet
and University of Amsterdam participants• Also having discussions with JGN2
• Coordinating with OGF on various schema - topology, path computation, signaling
• Working with the appropriate standards bodies - ITU, IETF, and OIF
