PlanetLab: A Distributed Test Lab for Planetary Scale Network ServicesOpportunities

• Emerging “Killer Apps”:– CDNs and P2P networks are first examples– Application spreads itself over the Internet

• Vibrant Research Community:– Distributed Hash Tables: Chord, CAN, Tapestry, Pastry– Distributed Storage: Oceanstore, Mnemosyne, Past– Lack of viable testbed for ideas

33 sites, ~3 nodes each:– Located with friends and family– Running First Design code by 9/01/2002– 10 of 100 located in manage colo centers, Phase 0 (40 of 300 in Phase 1)

– Disciplined roll-out

Synopsis

• Open, planetary-scale research and experimental facility• Dual-role: Research Testbed AND Deployment Platform• >1000 viewpoints (compute nodes) on the internet• 10-100 resource-rich sites at network crossroads• Analysis of infrastructure enhancements,

• Experimentation with new applications and services• Typical use involves a slice across substantial subset of nodes

New Ideas / Opportunities

• Service-centric Virtualization– Re-emergence of Virtual Machine technology (VMWare…)– Sandboxing to provide virtual servers (Ensim, UML, Vservers)– Network Services require fundamentally simpler virtual machines, making

them more scalable (more VMs per PM), focussed on service requirements.– Instrumentation and Management become further virtualized “slices”

• Restricted API => Simple Machine Monitor– Very simple monitor => push complexity up to where it can be managed– Ultimately one can only make very tiny machine monitor truly secure– SILK effort (Princeton) captures most valuable part of ANets nodeOS in

Linux kernel modules– API should self-virtualize: deploy the next PlanetLab within the current one– Host V.1 planetSILK within V.2 thinix VM

• Planned Obsolescence of Building Block Services– Community-driven service definition and development– Service components on node run in just another VM– Team develops bootstrap ‘global’ services

2003 2004 2005

V.0: seed100 nodes

V.1: get API & interfaces rightGrow to 300 nodes

V.2: get underlying arch. and impl. RightGrow to 1000+ nodes

• Minimal VM / Auth. requirements• Applications mostly self-sufficient• Core team manages platform

• Thin, event-driven monitor• Host new services directly• Host phase 1 as virtual OS• Replace bootstrap services

• Linux variant with constrained API•Bootstrap services hosted in VMs•Outsource operational support

Project Strategy

What will PlanetLab enable?

• The open infrastructure that enables the next generation of planetary scale services to be invented

• Post-cluster, post-yahoo, post-CDN, post-P2P, ...

• Potentially, the foundation on which the next Internet can emerge• A different kind of testbed• Focus and Mobilize the Network / Systems Research Community• Position Intel to lead in the emerging Internet
