NetIDE: Integrating and Orchestrating SDN ControllersDr. Pedro A. Aranda Gutiérrez, Telefónica I+D

Agenda

• Problem statement• NetIDE concepts and outcomes

• Framework• Architecture• IDE• Tools

• Results• Assuring the survival of the code beyond the project lifetime

Problem statement

• SDN promises to introduce agile Software development techniques in the way operators use their networks

• Shorter time to market• Reuse successful services

• However, there are different SDN platforms out in the market

• How to select one• Best of breed• Fit to purpose

• From vendor lock-in to platform lock-in?

The NetIDE framework

NetIDE aims at supporting the whole development lifecycle of network apps in a platform-independent fashion:• Integrated SDN development environment• Covering the full lifetime of SDN applications• It brings all the goodies of Software Design and

Development to Networking:• Platform independence• Code re-usability• Developer tools (debugger, profiler, logger, etc.)

The Network Engine

• Client/Server SDN controller paradigm of ONF• Network Application’s modules are given the runtime

environment they expect in the client controller• Multi-controller support (OpenDaylight, Ryu, Floodlight,

ONOS, …)• Backend: southbound plugin• Core Layer:

• provides a controller-independent means to compose apps and resolve conflicts between them.

• Provides a unified interface with the tools

• Shim Layer: northbound plugin

Mininet CLI

The topology editor

• Graphical editor to create and edit network topologies

• Imports the underlying topology from the NetIDENetwork Engine

• Topology generator produces configuration files for Mininet

Developer tools

Help developers to systematically test, profile, and tune their Network AppsØLogger: tracing capabilities to judge the performance of the

deployed Network AppØGarbage Collector: Cleans the switches’ memory from

unused flow rulesØModel Checker: systematically check app behaviour and

flag actions that lead to violations of the desired safety properties

ØProfiler: judging the impact of network failures on the Network App behaviour

ØDebugger: supports debug of packet processing (OFReplay, packet inspection and flow table checking)

Assuring results survive NetIDE

• NetIDE is finishing end of December 2016• However this does not mean that the results will die with

the project• We assure their survival by contributing them to different

FOSS projects

OpenDaylight

NetIDE is an OpenDaylight Project since the 26th of June, 2015.https://wiki.opendaylight.org/view/Project_Proposals:NetIDE

Shim is shipped as the NETIDE project with OpenDaylight Berylliumhttps://www.opendaylight.org/odlbe

Eclipse Marketplace

The IDE and related tools are available on the Eclipse Marketplace

http://marketplace.eclipse.org/content/netide

Makes it easy for people to test and adopt them

Floodlight

vNetIDE included among the authors and contributors of the Floodlight Controllerhttps://floodlight.atlassian.net/wiki/display/floodlightcontroller/Authors+and+Contributors

vArchitectural concepts ported to Floodlight: vSignal applications when an input event has been

consumedvDriving the execution flow of the controller: i.e.

delivering the network event only to specific applications in a specific order (overriding the controller’s default behaviour)

Github repository

Full source code of the last and best version of IDE, Network Engine and Tools are publicly available on Github under Eclipse Public License v1.0

https://github.com/fp7-netide

validateourframework.

In the way of a conclusion

• Multi-controller coordination allows us to• Choose best of breed• Build on proven building blocks instead of rewriting• Really capitalise on the “S” aspect of SDN

• NetIDE has produced a range of tools that realise software development paradigms in networks

• Using FOSS projects helped us concentrate on the essentials

• We are giving back (and assuring results survive the project)

So why not…

• Contributing to OPNFV?• Some components are

already in projects that are used within OPNFV

• We could consider contributing the code of other components

• Just contact ushttp://www.netide.eu
