  1. PlanetLab Inspiration and Partner for ENGINE Jiří Navrátil jiri@cesnet.cz

  2. 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

  3. GENI starting in the US and Europe

  4. 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 ?

  5. 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

  24. 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 !

  25. PlanetLab in frame of GREN (Global Research and Educational Networks)

  26. 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
