Network Discovery for POMBA and other Use Cases

Network Discovery for POMBA and other Use Cases SDNC Working Group June 13 2018

High-level Use Case Discovery of data from primary data sources (outside of ONAP) for use to help improve • data quality • information complexness In Casablanca, we will be providing data to POMBA 2 Information Security Level 2 – Sensitive © 2017 – Proprietary & Confidential Information of Amdocs

Network Resource Discovery The goal is to provide a building block to enable discovering data from primary data sources (those outside of ONAP) • Network Resources • • • Overlay, Underlay and between data centre Eventually be model-driven, self-service onboarding leveraging SDC Discover specific network resource • Keep complex modeling and stitching to higher-level code • Initial support for REST-based interfaces, can be expanded to other protocols • Uses an A&AI enrichment Microservice, but the discovery API and use case driven from SDNC • 3 Same Microservice used to support other use cases, but this is out of scope.

How to support Multi-VIM

Potential Roadmap Items • Multi-VIM Adapter, when appropriate • Fully model-driven network discovery, including on-boarding using SDC • Reuse of enrichment means invest once and both features can be modeldriven • Reconciliation of data • Policy driven • Updating of data sources or raising alarms based on report findings

Next Steps • Providing POMBA Session next week in face to face meeting • POMBA piece being added to Logging Project • Architecture committee agreed it could be brought in front of TSC for approval of scope change • Will call separate weekly meetings • Will start discussions with A&AI shortly • Network Discovery piece targeted for SDNC working group • • • Present to working group Epic and User Story drafted Resources lined up to do work Looking for thumbs up from working group Additional help reviewing or providing supporting content always welcome
