Solu5on: Ver5cally Integrated Stack == SDN Distribu5on

Project Atrium Goals 1. Integra5on

-‐  Create ver5cally-‐integrated open-‐source stacks -‐  From open-‐source components, OF1.3 & Hardware -‐  Enable network operators to download distribu5on from a single loca5on

2. Interoperability -‐  Enable mul5ple hardware vendors to plugin to stack -‐  Allows end-‐users to select different hardware classes for common use-‐cases.

3. Deployments -‐  Work hand-‐in-‐hand with operators on deployable use cases leading to trials. -‐ Give operators confidence in pure SDN solu5ons

Drivers use human intelligence to bridge the interoperability GAP.

They are specific to the following parameters:

1. Driver per pipeline ( HW-TTP concept) 2. Driver per application type ( SW-TTP concept) ( Routing, Switching, Overlays )

3. Driver sets per framework ( ODL, ONOS, RYU )
