3. DISCOVER, DISRUPT, DELIVER The Triple Virtuous Gears… … That need levers to go round

4. DISCOVER, DISRUPT, DELIVER The Road to a Network IDE The natural consequence of applying concepts and tools related to software development Supporting a complete design flow High-level definition and manipulation Validation from simulation to actual debugging Beta versions by slicing Phased deployment Integrate virtualized and non-virtualized functional elements Aligned with parallel IT development SDN Controller SDN Forwarder OVS

5. DISCOVER, DISRUPT, DELIVER Building Network Apps Based on the abstraction of a high-level, declarative programming language Network administrators specify how they want the network to look, who can talk to whom and how… High-level declarations and constraints are translated into low level instructions that each data plane element can implement The “hacks that vary by box, by vendor, by version, by deployment…” is the compiler’s problem

6. DISCOVER, DISRUPT, DELIVER The NetIDE Concept NetIDE aims at delivering a single point of entry to SDN development that support the whole development lifecycle of network controller programs in a vendor-independent fashion In short: A controller- and gear-independent approach to support the development of Network Apps Integrated development and tool support for the network design cycle in SDN environments New network layer services and the support for emulator-in-the-loop and simulator-in-the-loop configuration Open collaboration made possible not only at the deployment level, but since the initial inception and along the whole development phases

7. DISCOVER, DISRUPT, DELIVER The NetIDE Architecture

8. DISCOVER, DISRUPT, DELIVER Pulling the Levers Open collaboration in SDN/NFV has to go beyond pure open- source integration And embrace collaborative development Bring all potential actors onto a common base for app development Service providers, infrastructure manufacturers, software developers, researchers… From initial inception to actual deployment Supporting all the phases: design, development, and deployment Taking direct advantage of the technology itself A bootstrapping process Setting the ground for DevOps applied to network services An open ecosystem for network apps It is the apps, stupid!
