NSF FIND DTN MeetingReport Out

• At WINLAB, Rutgers University, NJ
• May 29-30, 2007

Synergies

• The main design drivers for the original Internet
  have changed.
• Future Internet driven by
• Mobility
• Router, and network mobility
• Endpoint mobility (nodes and services)
• Disconnections
• Contemporaneous end-to-end path is a special case
• Persistent storage in network nodes?
• Efficient Content Dissemination / Access
• Content-oriented networking
• Naming/Role-based networking / late-binding of
  intentional names
• Service-oriented networking
• Is this a special case of content-oriented
  networking?
• Are the above solved using a common overlay or in
  the core?
• Enhance core routing
• Redefine the functionality of the endpoint
• Build an overlay that takes advantage of the
  existing Internet

Content Dissemination/Access
6
Common Architectural Framework

• Introduction of functionality in the network
• Storage
• More hop-by-hop functionality
• A new kind of naming and addressing
• Persistent identifiers for endpoints, roles,
  services
• Content-addressability
• Leverage the existing DTNRG work
• DTN Architecture, Bundle Protocol, Bundle
  Security Protocol, Metadata Extension Block,
  Implementations, Related algorithms

7
Open Problems

• Routing
• Scaleable integrated approaches that work in
  wired, wireless, mobile, and DTN environments
• interplay with name resolution and content
  (including queries)
• Discovery
• Efficient peer discovery and association
• Available services and content
• Content issues
• Rights management
• Privacy
• Consistency and freshness management
• Designing the following into the system
• Network heterogeneity
• Diagnostics and manageability
• Security
• Context awareness
