Introduction and Context
HOPI Testbed V1 12 Sept, 2005

• Objective Evaluate new national scale
  architectures for future networks, How to put it
  all together
• Dynamic provisioning and control plane
• Hybrid networking
• Evaluate other related aspects applications,
  security, measurement , operations, engineering,
  AAA
• Evaluate ideas leading to the next-generation
  Internet2 network
• Current Resources National testbed
• 10 Gbps wave on NLR, Ethernet framed
• The Abilene IP network, including MPLS L2VPN
  tunnels when needed
• The MAN LAN Exchange Point - connection to
  NetherLight
• A 10 Gbps circuit from NYC to London, SONET
  framed
• HOPI Testbed Support Center (MAX, NCREN, IU)

Topic Areas - Optical Services
HOPI Testbed V1 12 Sept, 2005

• 2005 - Model future optical ideas using Ethernet
• Two level switch Switch full wave and virtual
  channels within a wave
• GMPLS implementation on servers controlling nodes
  - dynamic setup of services on the order of under
  a minute, across administrative domains
• 2006 - Add in a richer set of optical
  capabilities
• Richer backbone topology, with additional
  optical devices
• Add connectors
• Refine GMPLS capabilities, evolve cross domain
  issues, understand setup, duration, scheduling
  issues
• 2007-2009 - Examine optical switching
  capabilities
• Look at vendor control plane implementations
• Not really examining specific optical properties,
  but how they might be used
• Issues related to alien waves
• Optical packet switching?

Topic Areas - Optical Technologies
HOPI Testbed V1 12 Sept, 2005

• 2005 - Focus in testbed is to model optical
  technologies and how to use them for applications
• Strong emphasis on control plane issues
• 2006 - Examine optical technologies and how they
  might be deployed in the testbed and the
  next-generation network
• For example, OOO vs OEO issues
• Refinement of control plane ideas and issues.
• 2007-2009 - Deploy new optical technologies in
  the testbed as needed to understand
• Wave switching and conversion
• Greater than 10 Gbps transport/switching
• Security and measurement issues for new
  technologies

5
Topic Areas Interoperability
HOPI Testbed V1 12 Sept, 2005

• 2005 - Current Status
• HOPI doesnt focus on equipment interoperability
  at this time
• There is a strong focus on interoperability with
  other testbeds
• 2006 - Evolution towards testing various
  solutions. For example
• Control plane implementations
• Service planes supported on top of control planes
• We have yet to understand how application
  technologies will be supported
• Some emphasis on interoperability of optical
  devices
• 2007-2009 - Increased emphasis on
  interoperability as the testbeds adds new devices
• Continued emphasis on control plane activities

Key Themes
HOPI Testbed V1 12 Sept, 2005

• Focus now is much more on how to put it all
  together, rather than interoperability of optical
  devices. Looking at a single network approach.
  Strong involvement from Testbed Support Center
  (TSC)
• Dynamic provisioning and control plane (TSC)
• Hybrid networking
• Focus of applications (TSC)
• Additional key elements security, measurement,
  operations, engineering (TSC)
• Dynamic provisioning and control plane
• How dynamic - setup, duration, scheduling?
• Topological extent - from where to where?
• Across multiple domains? GMPLS/ASTN evolution?

Key Themes
HOPI Testbed V1 12 Sept, 2005

• Hybrid networking
• This issue exists in the multiple network
  approach, but is much simpler
• How does an application use the circuit based
  infrastructure?
• Whats the right mix of circuits and packets?
• Has to be transparent to the user
• Focus on applications
• In this new paradigm
• How will new technologies support applications?
• How will new technologies motivate new methods
  for applications?
• Application Topologies
• Note similarity to multiple network approach, but
  a slightly different viewpoint
• Optical multicast
