2 Outline Introduc)on to SDN to OpenDaylight New in Lithium Plans for Beryllium

3 Traditional SDN (OpenFlow) The separation of the and data planes Modern switches Control/data plane both on switch Data plane: fast, reads tables Control plane: slow, writes tables Control Plane CPU Switch Chip Ports, 1-6

4 Traditional SDN (OpenFlow) The separation of the and data planes Modern switches Control/data plane both on switch Data plane: fast, reads tables Control plane: slow, writes tables SDN Decouple /data planes Data plane on the switch Control plane elsewhere, e.g., an x86 server, can do fancier things Most features go here This gets smaller, turns into ler to switch chip translator SDN Controller Control Plane CPU Switch Chip Ports, 1-6

8 What is OpenDaylight OpenDaylight is an Open Source So8ware project under the Linux Founda=on with the goal of furthering the adop)on and innova)on of So8ware Defined Networking (SDN) through the crea)on of a common industry supported plaporm. Code Acceptance Community To create a robust, extensible, open source code base that covers the major common components required to build an SDN solu)on To get broad industry acceptance amongst vendors and users: Using it directly or through vendor products Vendors using OpenDaylight in commercial products To have a thriving and growing technical community contribu)ng to the code base, using the code in commercial products, and adding value above, below and around.

15 Source: OpenDaylight Community Like any Open Source Project, OpenDaylight primarily consists of those who show up to do the work. Running around 250 commits per week over 12 months, trending up 30 Days: ~625 commits, ~100 contributors (7/13/15 8/12/15) Spikes to ~2x this near releases 12 Months: ~13,250 commits, ~365 contributors (8/12/14 8/12/15) Strong integra)on and tes)ng community This stuff really magers

23 Beryllium Plans

24 Beryllium Release Focus on S3P, Documenta)on, Migra)on, and HA/clustering Tries to balance maturity (the above) with feature velocity Some projects will be mature Some of the Karaf features in mature projects will be stable Stable features will have S3P, Migra)on, and HA/clustering requirements Stable and normal distribu)on; stable only has stable features Driving appropriate projects/features to mature/stable Offset 0: Controller, MD- SAL, NETCONF, AAA, YANG Tools, odlparent Release Plan: hgps://wiki.opendaylight.org/view/simultaneous_release:beryllium_release_plan
