  • Motivating examples
    • More control over routing decisions
    • Bootstrapping networks: Zero device-specific config
    • Joint control of data plane mechanisms
    • Detecting/preventing end-system created security holes
  • Dissemination plane – any two nodes with a physically connected path should be able to communicate
    • Should this be a goal to shoot for?
    • Does it require research or just engineering?

  • Does the e2e principle have anything to say about control/management?
  • Minimize what 4D does – boot strap the network and then use existing mechanisms/management systems?
    • RSVP
  • With a broader view of both data (distributed) and VoIP (centralized), It\'s daunting to tackle the full complexity that arises
research problems
Research Problems
  • Is it important to have a way to always talk to all nodes in the network so long as there is a physical path between the nodes? What is the best way to achieve this?
  • How deep should discovery be pushed into the end-systems? Is there a general abstraction that can express the kinds of configurations seen today and the likely into the future?
  • How should decision logic be structured?
concrete steps
Concrete Steps
  • Establish classic problems to use as benchmarks
    • Integrating a new router into a network using OSPF as an IGP
  • Establish measures for success
    • How to compare two different architectures?
  • Create a problem-formulation and call-to-arms paper
