  1. Delivering Circuit Services to Researchers: The HOPI Testbed Rick Summerhill Director, Network Research, Architecture, and Technologies, Internet2 Joint Techs 18 July, 2005 Vancouver, BC, CA

  2. Agenda • Announcements • Thoughts about the next generation Abilene • The HOPI testbed • Current status

  3. HOPI Project - Summary • In the near future we will see a richer set of capabilities available to network designers and end users • Core IP packet switched networks • A set of optically switched waves available for dynamic provisioning • Fundamental Question: How will the core Internet architecture evolve? • Many options being examined • Examine a hybrid of shared IP packet switching and dynamically provisioned optical lambdas • HOPI Project – Hybrid Optical and Packet Infrastructure • Dynamic Provisioning - setup and teardown of optical paths • Hybrid Question - how do hosts use the combined packet switched and circuit switched infrastructures?

  4. HOPI Supporters • Equipment • Force 10 - Ethernet switches • HP - control, measurment and support servers • Glimmerglass - Optical (white light) switches • Advisory • The HOPI design team • The HOPI corporate advisory team • Soon to be announced HOPI research advisory panel • Management • The HOPI TSC - MAX, NCREN, and IU • The ITECs in the near future • Internet2

  5. HOPI Testbed Support Center • Call for proposals several months ago • Received 4 responses, all excellent • The TSC is a collaboration between MAX, NCREN, and the GRNOC at IU • Advanced engineering and design focus • Implement control plane activities • The MAX GigaPoP (and Dragon) will focus on these issues • Coordinate application activities • NCREN will focus on these issues • Manage and engineer the facility • GRNOC at IU will focus on these issues

  6. Abilene Next-Gen Network Futures • October 2007 - End of recent 1-year Abilene transport MoU extension • Sets next-generation network planning timeline • Architecture definition: 1/1/2006 • Transport selection: 4/1/2006 • Equipment selection: 7/1/2006 • Backbone deployed: 1/1/2007 • Connector transition: 2007 • Concurrently, review overall business plan and management model • Network design time frame: 2007-2012 • Note that ESnet transport agreement with Qwest Federal is on similar time line - December 2007 • HOPI testbed is expected to be in place for 3 years, to experiment with future protocols • Refine and evolve next generation architecture

  7. Backbone Footprint • Basic component will be ITU grid waves that interconnect nodes on a national fiber footprint • Expected to be anywhere from 10 to 40 waves • Bandwidth of each wave expected to be 10 Gbps (and possibly 40 Gbps) • Switching nodes between segments • Schematic:

  8. Switching Capabilities • Through an optical interconnecting device that serves 3 purposes: • Provides a client interface to connecting network • Provides access to waves on the network • Provides support for sub channels on a wave • i.e. Ethernet VLANS, SONET paths, or other suitably framed capacity.

  9. Connector Interface The interface to the backbone: • Two or more client interfaces between optical interconnects (analogous to router-to-router connections today) • Requirements: • Support connectivity to IP Network • Support multiple sub channels through backbone to other RONs up to capacity of interface HOPI testbed to help refine ideas

  10. The HOPI Testbed • Build a national scale testbed to examine architectural issues • Use the facilities from Internet2 and NLR • The Abilene network • The Internet2 wave on NLR • MAN LAN • An OC-192c circuit to London for connecting to GEANT testbeds • The RONs • Use the testbed to model many of the issues that arise in the next generation design • Refine architectural models over the next few years

  11. HOPI Questions • Examine how to build an architecture • A lot is known about how to do various pieces • The main question is how would one put it all together into a network • Problems to understand • When does a host use the circuit switched infrastructure and when does it use the packet infrastructure? • How are the circuit and packet switched infrastructures integrated? • Temporal degree of dynamic provisioning • Temporal duration of dynamic paths and requirement for scheduling • Topological extent of deterministic provisioning • Examine backbone, RON, campus hierarchy – how will a RON interface with the core network? • Understand connectivity to other infrastructures – for example, international or federal networks? • Network operations, management, measurement, and control plane across administrative domains?

  12. HOPI General Problem

  13. HOPI Topology

  14. HOPI Deployment • Installed node locations • Los Angeles Equinix facility - same location as NLR node • Washington, DC MAX/Dragon facility - same location as the NLR node • StarLight in Chicago • The Pacific Northwest GigaPoP in Seattle - Westin Building, and new location of the NLR node • Future node locations • New York City – NYSERNet area in 32 AoA - same location as NLR node (many thanks to NYSERNet for donating rack space and power to support the HOPI project). • Looking at additional possibilities as the southern route of NLR is installed • Circuit from NYC to London • Early October, 2005

  15. HOPI Node

  16. HOPI Connector Interface and Basic Service • Basic Service • 1 or 10 GigE channels (may add to this list in the future) • Connector Interface • A 1 or 10 GigE connection to the fiber cross connect, either dark fiber or a provisioned service • An MPLS L2VPN service through Abilene to the Ethernet switch • Provides immediate connection to the Internet2 NLR wave from Abilene • May add basic services and interface types at later stage • Current planned connectors/peers • Ultralight • Ultrascience net • ITECs

  17. How do you Connect to the HOPI Testbed? • Connections • Bring a 1 GigE or 10 GigE fiber connection directly to a node for connection to the optical switch • Create an MPLS Ethernet VPN across the Abilene connection terminating at the Ethernet switch • Note: • Connecting to HOPI is not about obtaining additional bandwidth • Rather, it’s about participating in the experiment • Control plane development and deployment is essential • Working on integrating particular applications • Working with the HOPI TSC

  18. References • To request a connection to the HOPI testbed, send email to • hopi@internet2.edu • HOPI Call Center: 877 472-2419 • Active 9/25/2005 • Additional Information • http://abilene.internet2.edu • http://www.nationallambdarail.org • http://hopi.internet2.edu • abilene@internet2.edu
