## Introduction and Context

- 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

- 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

- 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

## Topic Areas:  Interoperability

- 2005 - Current Status
- HOPI doesn’t 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

- 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

- Hybrid networking
- This issue exists in the multiple network approach, but is much simpler
- How does an application use the circuit based infrastructure?
- What’s 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
