AgendaAgenda

• Announcements

• Thoughts about the next generation Abilene

• The HOPI testbed

• Current status

HOPI Project - SummaryHOPI 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?

HOPI SupportersHOPI 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 CenterHOPI 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

Abilene Next-Gen Network FuturesAbilene 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 FootprintBackbone 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 CapabilitiesSwitching 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 InterfaceConnector 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 TestbedThe 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 QuestionsHOPI 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?

HOPI DeploymentHOPI 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

HOPI Connector Interface and Basic ServiceHOPI 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?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
