Key Themes / Issues

• Not a single network but a set of facilities,
  capabilities and services to build both
  experimental and production networks at various
  layers, allowing members to acquire dedicated
  (project specific) facilities or shared
  (community specific) facilities as appropriate.
  Aka MORPHnet from NLR
• Focus on Regional Networking
• RPoPs facilitate development of local networks
• Provide delivery points for advanced services
• Grid compute nodes
• Video MCUs
• Measurement points
• Redundancy for application services
• Build a facilities-based network
• BE FLEXIBLE!
• Regional Point of Presence

18
Key research / issues

• Control-plane
• Bringing together the community of researchers
  investigating techniques to dynamically provision
  network capacity
• Integration with applications
• Helping eScience integrate dynamically
  provisioned networks into their applications
• Optical Networking
• Facilitating the sharing of information by
  research and education networks, developing best
  operating practices and service offerings
• Operations/Management
• Reliability, scalability, flexibility
• Money (funding/pricing/cost recovery, etc)

19
NCREN 5-year Roadmap (Interoperability Issues)

• Support of client alien waves
• RON-RON
• Service mapping
• Service interoperability
• Resource allocation/provisioning
• RON-backbone
• Service mapping
• Service interoperabilityResource
