Session ID: SFO17-313 Session Name: ODP for NFV Use - SFO17-313 Speaker: Honnappa Nagarahalli Track: LNG ★ Session Summary ★ To support the use of OpenDataPlane in Network Function Virtualization environments, we are developing support structures to permit a single binary to be packaged for distribution by platforms like RedHat, Ubuntu, SUSE, etc. that can offer both high-performance software implementations of ODP APIs as well as hardware-acceleration on platforms that offer such. --------------------------------------------------- ★ Resources ★ Event Page: http://connect.linaro.org/resource/sfo17/sfo17-313/ Presentation: Video: --------------------------------------------------- ★ Event Details ★ Linaro Connect San Francisco 2017 (SFO17) 25-29 September 2017 Hyatt Regency San Francisco Airport --------------------------------------------------- Keyword: http://www.linaro.org http://connect.linaro.org --------------------------------------------------- Follow us on Social Media https://www.facebook.com/LinaroOrg https://twitter.com/linaroorg https://www.youtube.com/user/linaroorg?sub_confirmation=1 https://www.linkedin.com/company/1026961

WORKING TOGETHER
ODP Cloud - Key Components
Modular Framework - Helps to implement subsystems for various ODP
components
Platform Discovery – Identifies various components in the platform and
matching libraries
Module loader - Allows to load libraries and register implementations into
subsystems
Device Driver Framework - Framework for writing the drivers

7. ENGINEERS AND DEVICES

Next Steps
User Space Drivers for NICs and vNICs
ODP Component Optimizations
Components derived from Linux-Generic
Platform discovery and library load infrastructure
Single repository for ODP
Directory structure changes
Build changes
