5 I Believe a Federated SDI World Will Soon Look Like This Bob the Consumer Richie the ISP Sheldon the Startup SDX 1 SDX n Internet2 AT&T Verizon StarLight other WANs SDN 1 e.g. university SDN 2 e.g. city SDN 3 e.g. coffee shops SDN 4 e.g. airport SDN 5 e.g. government SDN 6 e.g. utilities SDN 7 e.g. household

6 Federated SDI is Very Feasible Today: Four Game Changers Game New enabler Changer #1 #1 Game New enabler Changer #2 #2 Open compute Easy to deploy a compute/rack/dc Cloud technology enters a new phase Open standardized API Open network Flexible, lower cost to add new network OpenFlow, and other SDNs Open standardized API Game New enabler Changer #3 #3 Game New enabler Changer #4 #4 Open framework for Apps platform + front end + backend Open platforms with upgrade path Open business models Network Function Virtualization (NFV) Open templates for services (Amazon, GENI, Open Stack, Cloudstack)

7 Essentially a Cloud-centric World On-demand Compute and Network Challenges Service availability (Hard) Data/application lock-in Data confidentiality WAN network bottleneck Unpredictable performance Scalable storage Debugging large distributed applications Automatic scaling Reputation fate sharing Software licensing Solutions Ubiquitous access to multiple clouds Open standard platform Easy insertion of cloud-based security service Low cost switching may bring affordable WAN alternatives, data transfer service Advances in virtualization technologies; lower cost means more low cost hardware for customization of special need applications Many scalable store options Open compute and network stacks; easy insertion of debug process or VMs Customize your own cloud! Mature support for service migration Companies offering cloud pricing models Inspired by 2010 Berkeley Rad Lab reported 10 obstacles to cloud computing

8 THE BUILDING BLOCKS

9 Open Programmable Network and Compute Gaining Maturity Software defined networking stack (Big Switch/Floodlight example) Cloud compute/storage stack (OpenStack example)

10 Open Programmable Inter-domain WAN Network Service Interface (NSI)

11 Open Programmable SDN Core: Internet2 AL2S

12 Federation Framework Brings Pieces Together: an example - GENI Rspec

13 The Most Important Element: People, Institutes, Policy With EU FIRE G-Lab With US Institutes GENI CC-NIE ACI-REF

23 A Proposal To the Community A major paradigm change is coming, it s the time to take bold steps to shape it. The top challenge is in the organization policies, processes The infrastructure building blocks are primed but still morphing we know pretty well how to build them, though what we need is to find out how we will use them The proposal lets begin with an open federated SDI, place emphasis on policies, and software to enforce the policies This should make sense to BOTH the R&D AND the commercial sectors Remove barriers for anyone to get resource, but focus on how to monitor, optimize, and control what they do with the SDI resource
