Basic Premise
• Large science projects have become, or are becoming, global collaborations • Multiple investigators• Multiple physical locations• High-Performance infrastructure required
to support scientific investigations and collaborations
![Page 3: ASCR/ESnet Network Requirements an Internet2 Perspective](https://reader036.vdocument.in/reader036/viewer/2022062409/56814fc3550346895dbd7f8d/html5/thumbnails/3.jpg)
Reframing the Science needs Question
• Conclusion based request• I need 5 Gbps of bandwidth
• Science based request• I need to move 2 TBytes in 1 hour• I will move this amount of data once per
day
• Users need ways to make effective complaints

Internet2 Collaboration Model
• Direct support to member institutions
• Indirect support for most funded member lead research projects
• Direct collaboration on specific funded research projects
![Page 12: ASCR/ESnet Network Requirements an Internet2 Perspective](https://reader036.vdocument.in/reader036/viewer/2022062409/56814fc3550346895dbd7f8d/html5/thumbnails/12.jpg)

Middleware and Security
• Shibboleth• Multi-institution single sign-on (SSO)
service
• Grouper• Groups Management toolkit
• COmanage• Identity-oriented requirements of common
collaboration tools

Current Control Plane Developments• Intra-domain
• Currently on the Ciena platform, to be deployed on the Infinera platform in the future
• Have an Installed working configuration on the Cienas
• Inter-domain• Working with the DICE (Dante, Internet2, Canarie/LHC,
ESnet) group• Working on Topology, Path Computation and
Scheduling, Signaling, and Lookup Services (think a circuit based DNS)
• Web service based communications• Face-to-face meeting every three months and biweekly
calls

Conclusions
• Internet2 is a “Member focused, Member led” organization
• Works closely with DOE, NSF and other Fed agencies to support community
• Strong collaborations with partners and peers
• Comprehensive set of services to support high-performance scientific collaborations

Using the Network
• Application’s performance should meet your expectations!• 100 MB/s is reasonable• 1000 MB/s is possible
• If they don’t you should complain!• But you need to complain effectively if you
want the problem fixed

Web Service based E-NNI
• Routing• Topology Exchange• Domain Abstraction• Varying levels of dynamic information
• Resource Scheduling• Multi-Domain path computation techniques• Resource identification, reservation, confirmation
• Signaling• path setup, service instantiation
• Host Lookup Service• Uses DNS pointers

Dynamic Circuit NetworksWeb Service Control Plane Interfaces
• Web Services provides a mechanism to deal with heterogeneous control planesinspired by the standards bodies work on control plane protocols, but
not just recreating that work at the web service level

Shared IP Network
• Juniper routers at 9 locations• 10 Gbps links interconnect routers• 20 Gbps on multiple links as required
• Router proxy allows access to current config’s and statistics
• Internet2 Observatory provides detailed utilization information

Dynamic Circuit Network
• 21 Ciena Core Director multiplexor sites
• Dedicated circuits between 2 points• site-to-site, cluster-to-cluster, or host-to-
host• One end-point may be non-Internet2 site• Bandwidth steps from 51 Mbps to 10 Gbps• Short duration (minutes to weeks)• Long duration (weeks to years)

Dynamic Circuit Network
• Similar to the IP network model, but using different protocols
• Connections are one armed• Physical connection• Control Plane Protocols
• Create Circuits in seconds for periods of hours to days
• Only through the Ciena equipment at the start, eventually evolving to the full platform
