Talk overview

• First set of questions
• What is the relation ENGINE and PlanetLab
• Convergence of ENGINE and NREN infrastructure
• Second set of questions
• How to understand ENGINE a new sort of testbed

GENI starting in the US and Europe

My impression of it and first set of questions

• Too general picture to understand it
• What is main difference ENGINE and the other
  testbeds ?
• Who are the main users and main purpose of
  ENGINE ?
• if computer scientists, they are sitting in the
  University campuses
• How to connect them into the ENGINE ?
• If new Network applications
• Who are its users, who provide the servers ?
• Why the principles used in PlanetLab are the key
  points for GENI ?

PlanetLab main goals

• PlanetLab is concorcium of the Universities and
  academic institutions established in 2002 by 3 US
  universities (UC Berkeley, UofWashington, and
  Princeton University) with the goals which can be
  shortly described in three main points
• to provide infrastructure for planetary scale
  experiments with networking services
• to provide platform for new novel services with
  real users
• to catalyze the evolution of the Internet to new
  service-oriented architecture

What type of users and applications can utilize
this architecture ?

• NREN itself ?
• YES for Network engineering
• ordinary Internet users ? Why ?
• Researchers and research teams ?
• Yes but who is ready ? (HW, SW, people)
• Modern network applications
• Yes, they are ready in PlanetLab !

Educational Networks)
28
Existing tools and network applications can be
re-implemented or extended into new architecture !

• Peer-to-Peer Systems (DHT Distributed Hash Table)
  
• CAN, Chord, Pastry, Tapestry (building
  routing tables adaptively, automatic
  reconfiguring, using effective algorithms)
• Systems using effectively whole available
  infrastructure
• CDN Content Distributed Network
• Replication and other systems based on
  Behive principles with O(1) lookup, Load peak
  multiplexing
