  • 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
