7 Slide 7 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

8 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. Dynamic Circuit Services

9 Slide 9 Multi-Service/Domain/Layer/Vendor Provisioning Regional Network Internet2 Network ESNet Dynamic Ethernet TDM GEANT IP Network (MPLS, L2VPN) Ethernet Router SONET Switch Ctrl Element Domain Controller LSP Data Plane Control Plane Adjacency Multi-Domain Provisioning Interdomain ENNI (Web Service and OIF/GMPLS) Multi-domain, multi-stage path computation process AAA Scheduling TDM Slide from Tom Lehman, ISI-East GUI XML AST

10 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. Dynamic Circuit Services Applications

11 Slide 11 Example: E-VLBI Application Specific Network Correlator/Compute Cluster Mark 5 VLSR Analysis station VLSR Global R&E Hybrid Infrastructure Globally Distributed, Unified Storage Clusters Sensors Slide from Jerry Sobieski, MAX

12 Slide 12 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
