The HOPI Project Linda Winkler Argonne National Laboratory winkler@mcs.anl.gov HOPI Design Team Co-Chair GNEW2004 CERN, Geneva, Switzerland March 16, 2004 This is a general overview presentation about Internet2. Internet2 is a consortium, led by US universities, which is recreating the partnership among academia, industry and government that fostered today’s Internet in its infancy.

(Perceived) Problems Today Given current technology, Abilene is a viable shared packet infrastructure. By 2006 when the current UCAID Qwest contract expires will the available technology drive us toward another architecture? Some discipline specific networks have enormous bandwidth requirements High Energy Physics Community Square Kilometre Array Community Problems with packet infrastructures Variation in throughput, delay, jitter on shared packet infrastructures. Will we have 40 Gb/s or 100 Gb/s in near future? Or more likely n*10G waves. Increasing demand for deterministic paths. Demand for more dynamic requirements on bandwidth and topology. 11/20/2018

Looking to the Future Examine potential new architectures Advanced infrastructures Packet-based network to support basic functionality and application development. A pool of optical switched waves that support creation of dynamic networks for specific users or disciplines. Examining a Hybrid architecture of dynamically provisioned Optical lambdas and IP Packet Infrastructure 11/20/2018

Deployment Issues with Potential New Infrastructures How do you define deterministic behavior? How close to end nodes should optical waves be switched? Where is the new edge? How dynamic must optically switched paths be? What duration do we expect of dynamic paths? What is the interaction between the packet infrastructure and the dynamically created paths or the networks they form? May require new measurement and troubleshooting paradigm. What are the interconnectivity requirements to end systems, other research infrastructures (for example, international or federal networks or infrastructures)? 11/20/2018

Abilene-NLR Overlay 11/20/2018

MANLAN Experimental Facility MANLAN Proper is an Ethernet Exchange Point for R&E Networks Addition of Cisco 15454 to support projects such as the Global Lambda Integration Facility (GLIF) Current IEEAF/Tyco Circuit between Surfnet and Abilene will be used for international experimentation Connections CA*net Abilene Surfnet Some near term tests: Lightpath consisting of a variety of technologies crossing multiple administrative domains There are many other experimental facilities – StarLight (including Starlight-CERN OC192 link with Layer 2 and 3 services), NetherLight, etc. 11/20/2018

HOPI Basic Service Probably a 1 GE end-to-end path with “reasonable” jitter and latency properties Dynamically provisioned – understand degree to which temporal setup is needed Understand topological extent – for example, host-to-host? Cluster-to-cluster? Examine Backbone, RON, Campus hierarchy – understand interface options Network operations Measurement activities 11/20/2018

HOPI Testbed – Potential Model 11/20/2018

Current Status Design team furiously working on definitions for: Basic services model HOPI node design Connector interface Control plane requirements Management requirements Target draft whitepaper for Spring (Apr) Internet2 Members meeting Planned testbed(s) implementation this year. 11/20/2018

Conclusions Support More Information Internet2 goal is to support the bandwidth needs of the community as networking infrastructures evolve in the future through shared, high-performance packet networks and dedicated capabilities as required.
