Objectives

  • Software prototypes of main arch. pieces with end‐to‐end

protocol implementations

  • Consider OpenFlow/SDN, FPGA platforms, and optical components
  • Mobility, first
  • Mobile host platforms and multiple wireless access technologies
  • Ad hoc, disconnection, network mobility as common cases
  • Meaningful at‐scale evaluation
  • Realistic network conditions
  • Access‐Core‐Access evaluations
  • Target long running deployment and opt‐in users

  • Applications, applications, applications
  • Deploy and evaluate GNRS services across full

GENI backbone and Spiral 4 GENI racks (~80‐100 nodes)

  • Deploy MobilityFirst services in overlay mode
  • ver the commodity internet
  • Even larger scale with emulation co‐deployment
  • Multi‐domain deployment using world‐wide
