7 What made PlanetLab successful? Centralized trust Centralized resource control Decentralized management (unbundled management) The bandwidth as free Provide only best-effort service Make Linux the execution environment Do not provide distributed OS services (up to users) Evolve the API Self-Scaling Architecture [Tom Anderson, Timothy Roscoe, Learning from PlanetLab, WORLDS06] [Aki Nakao] 7AsianFI 2008 Summer School

8 Self-Scaling Architecture (as in P2P) Consortium Loosely bound Membership Agreement Donate a few resources At least two machines (minimum H/W requirement) Bandwidth Tit-for-Tat Resource reciprocity The more join, the more useful the system becomes Primary incentives in P2P applications 8AsianFI 2008 Summer School

11 GENI (briefly) with courtesy to GPO Global Environment for Network Innovation How we use GENI, how we build GENI? GENI Spiral 1 / Prototype Disclaimer: I have been granted permission to use these slides from Chip Elliott and Aaron Falk And present these on behalf of them so that we share what is going on outside Asia. 11AsianFI 2008 Summer School

12 12 The GENI Vision A national-scale suite of facilities to explore radical designs for a future global networking infrastructure Mobile Wireless Network Edge Site Sensor Network Federated International Infrastructure Programmable & federated, with end-to-end virtualized slices Heterogeneous, and evolving over time via spiral development Deeply programmable Virtualized

13 AsianFI 2008 Summer School13 How to use GENI: A bright idea I have a great idea! The original Internet architecture was designed to connect one computer to another – but a better architecture would be fundamentally based on PEOPLE and CONTENT! That will never work! It wont scale! What about security? Its impossible to implement or operate! Show me!

14 AsianFI 2008 Summer School14 Trying it out My new architecture worked great in the lab, so now Im going to try a larger experiment for a few months. And so he poured his experimental software into clusters of CPUs and disks, bulk data transfer devices (routers), and wireless access devices throughout the GENI suite, and started taking measurements... He uses a modest slice of GENI, sharing its facilities with many other concurrent experiments.

15 AsianFI 2008 Summer School15 It turns into a really good idea Boy did I learn a lot! Ive published papers, the architecture has evolved in major ways, and Im even attracting real users! His experiment grew larger and continued to evolve as more and more real users opted in... Location-based social networks are really cool! His slice of GENI keeps growing, but GENI is still running many other concurrent experiments.

16 AsianFI 2008 Summer School16 Experiment turns into reality My experiment was a real success, and my architecture turned out to be mostly compatible with todays Internet after all – so Im taking it off GENI and spinning it out as a real company. I always said it was a good idea, but way too conservative.

17 AsianFI 2008 Summer School17 Moral of this story GENI is meant to enable... Trials of new architectures, which may or may not be compatible with todays Internet Long-running, realistic experiments with enough instrumentation to provide real insights and data Opt in for real users into long-running experiments Large-scale growth for successful experiments, so good ideas can be shaken down at scale A reminder... GENI itself is not an experiment ! GENI is a suite of facilities on which experiments run GENI creates a huge opportunity for ambitious research!

18 AsianFI 2008 Summer School18 GENI Spiral 1 has now begun! First results expected in 6-12 months GENI Project Office Announces $12M for Community-Based GENI Prototype Development July 22, 2008 The GENI Project Office, operated by BBN Technologies, an advanced technologies solutions firm, announced today that it has been awarded a three year grant worth approximately $4M a year from the US National Science Foundation to perform GENI design and risk-reduction prototyping. The funds will be used to contract with 29 university-industrial teams selected through an open, peer-reviewed process. The first year funding will be used to construct GENI Spiral 1, a set of early, functional prototypes of key elements of the GENI system.

19 AsianFI 2008 Summer School19 1 st GENI Solicitation – proposal areas

21 AsianFI 2008 Summer School21 GENI Engineering Conferences Meet every 4 months to review progress together 3 rd meeting Oct. 28-31, 2008 in Palo Alto, open to all Reviews current GENI status, Working Group meetings Also discuss GPO solicitation, how to submit a proposal, evaluation process & criteria, how much money, etc. Travel grants to US academics for participant diversity Subsequent Meetings, open to all who fit in the room Held at regular 4-month periods Held on / near university campuses (volunteers?) All GPO-funded teams required to participate Systematic, open review of each Working Group status (all documents and prototypes / trials / etc.) Also time for Working Groups to meet face-to-face Results in prioritized list for next round of prototype funding areas (priorities decided by NetSE Council and GPO)
