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.

3. (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.

4. 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

5. 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)?

9. MANLAN Experimental Facility
MANLAN Proper is an Ethernet Exchange Point for R&E Networks
Addition of Cisco 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. 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

13. 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.

14. 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.
