Sponsorship

• Co-Sponsored by Department of Energy (DOE) and
  NASA. Hosted by NASA Research and Engineering
  Network (NREN). Organized in cooperation with -
• The Federal Large Scale Networking Coordination
  Group (LSN) and the LSN Joint Engineering Team
  (JET).

Workshop Objectives

• ONT-2 Has Been Designed As a Forum That Will
  Assist In Creating the Means to Transition the
  Community and Its Networking Infrastructure to
  Leading Edge, Next Generation Optical Networks.
• This Forum Will Create Clear
• Content
• Long and Near Term Objectives
• Roadmaps (Multiple Not a Single Master Roadmap)
• Processes
• Activities that Will Achieve Goals Over Time
• On-Going Mechanisms to Ensure Real Forward Process

4
Workshop Organizational Background

• Workshop as Organized As The Logic Next Event
  Following to the August 2004 Workshop on Optical
  Network Testbeds (ONT-1)
• ONT-2 Will Move Beyond the ONT-1 Recommendations
• ONT-2 Will Development Specific Frameworks for
  Community Action, To Achieve Workshop Goals
• ONT-2 Has Not Been Organized To Resolve Or Even
  Address All Issues, or To Create All Required
  Processes.
• ONT-2 Will Begin To Initiate a Longer Term Set of
  Processes

5
Workshop Conceptual Background

• Recognition of the Relationship Among
• Basic Research and Experimentation
• Early Prototypes
• Early Implementations
• Production
• Wide Adoption
• On-Going Technology Renewal
• With Major Demarks, Inflection Points During
  Key Periods (e.g., Today!)
• Recognition That Forward Progress Requires
  Specific Activities, Gathering Information,
  Formulating Plans, Obtaining Resources, Removing
  Barriers, etc.
• It Is Also Important to Recognize Other Existing
  Related Processes and Contributions, Such as
  Standards Bodies, International Processes and
  Organizations, e.g., GLIF etc.

6
Content Objectives

• A Key Goal of the ONT2 Workshop Has Been to
  Gather a Substantial Amount of Information from
  Existing Advanced Optical Network Testbeds,
  Prototype Networks, Production Networks, and RE
  Networking Community.
• A Major Objective Is to Develop Processes for
  Positively Acting On That Information.
• However, This Forum Will Not Be Expected to Fully
  Develop that Information Or To shape Those Future
  Processes
• These Completion Tasks Will Be Undertaken
  Following the Workshop.

7
Optical Services And Technologies

• The Basic ONT-2 Focus Is On Optical Services And
  Technologies L1, Lightpath Based (lambda-based)
  Services, Not L3 or Other Networking
  Technologies, e.g., Wireless, Satellite, etc
• Multiple Other Forums are Devoted to These
  Technologies
• Optical Technologies Are Complementary To Other
  Options
• Addressing L2 Switching As It Relates to L1
  Services is Acceptable.
• Applications have been addressed extensively in
  other forums and documents
• Ref iGRID2005 Premier Showcase of Advanced
  Applications Enabled By Optical Networks

8
ONT-2 Participants

• Participants (Invitation Only) Represent
• Basic Research Testbeds
• Innovative Prototype Networks
• Production RD Networks, Including JETnets, and
  Selected RONs
• International RD Networks
• Network Technology and Service Providers,
• Senior Engineering and RD Managers from LSN
  Agencies and Partner Organizations.

Workshop Structure Part 1 (Afternoon of Day 1
and Morning of Day 2)

• Panels, Key Themes and Issues, 5 Year Roadmaps
• Processes and Goals
• Intermediate, Prototype Networks Used to
  Transition Between Testbeds and Production
  Networks.
• Primary Issues, roadmap harmonization,
  interoperability, service definitions, community
  involvement.
• Barriers, Challenges, Solutions to Barriers,
  Challenges

10
ONT-2 Panels

• Panel A Breath First, Technology Evaluations,
  Early Implementations
• Panel B Depth First Basic Research Testbeds
• Panel C JETnets With Testbeds
• Panel D JETnets Requiring Testbeds networks
  which primarily want to position themselves
  downstream from non-own ONT technologies, systems
  and services developments
• Panel E Basic Research From a 5-15 Year
  Perspective
• Panel F Industry Perspective

11
Key Themes and Issues

• Panelists Will Present and Discuss-- Key Issues
• Highly Important, Highly Disruptive Capabilities,
  Technologies
• Key Technologies
• Key Research -- (What is being done, What Should
  Be Done)
• Radically New Processes, Business Models
• Explication of Why These Issues/Themes/Problems
  Are Critical and Must Be Addressed
• Key Problems That Should be Addressed and
  Potential Solutions
• Major Technology Challenges
• Absence of Required Processes
• Insufficient Funding
• Inappropriate Business/Service Models
• Artificial Policy Barriers
• Artificial Organizational Barriers

12
Research Topics

• Diversity Among Research Testbeds Is a Valuable
  Objective
• What Research Is Being Undertaken? What Is
  Required?
• What are the Key Technical Challenges?
• What Are the Key External Challenges (e.g.,
  Funding, Technology Transfer, Communication Among
  Peers)?
• What Has Been Discovered?
• What Is Near Term? What Is Long Term?
• Participants Are Asked Not To Try to Anticipate
  What Other Communities May be Developing.
• Requirements Vary Among Activities
• In Initial Technology Investigation, Divergence
  of Approaches, Architecture and Technologies Is
  Valuable
• To Accomplish Quality Research, It Is Important
  To Explore Alternative Options.

13
Roadmaps

• The ONT-2 Workshop Will Compare Roadmaps, Not
  Reconcile Them
• Roadmap Dimensions
• Y-Axis
• X-Axis
• Optical Network-Based Services
• Optical Technologies
• Interoperability Capabilities, e.g., With Regard
  to Services Specified

  Prepare In Advance for the Active, Productive
  Discussion of Topics, Frameworks and Processes,
  For Comparing Related Roadmaps, For Developing
  Recommendations
• They Will Compare Roadmaps, But Not Try to
  Reconcile Them
• They Will Try to Obtain Community Preconsensus
  about frameworks and processes for groups of
  networks and testbeds to work together following
  the workshop.
• The Goal is IETF-TypeRough Consensus, Not
  Perfect Agreement
• Session Discussions Will Include Possibility of
  Identifying Common Goals Among Sets of Related
  Roadmaps Following the Workshop
