Transcript of PlanetLab Inspiration and Partner for ENGINE Jiří Navrátil [email protected].
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

ENGINE users and applications
Cheap and flexible infrastructure for many scientific users and wide spectrum of network applications
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
http://coblitz.codeen.org:3125/http://ephyra.cvut.cz/links/tmp/FLOWS/CVUT/RAW/rawflow.02-15-2006.5
In internet all peers are connected (logical full mesh)
Can users utilize all infrastructure effectively?
BitTorrent
