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 !

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

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

In internet all peers are connected (logical full mesh) Can users utilize all infrastructure effectively?
