Discussion about CPS & DCAE DES concept sharing



DCAE minutes: 2020-11-04 DCAE Meeting Notes#20201104DCAEMeetingNotes-Recording:

  • DCAE / Data Exposure Service DES (new R7 Microservice ) - Fetch data send REST query make use of templates, aggregation present to user. abstracts data layer for performance and data.

  • DES & CPS - Maybe CPS could follow a similar approach to DCAE/DES. SQL templates. Possible S/W sharing? A CPS user (model/yang) driven. To do a query, the consuming mS composes an XPath (composite) query. To abstract the query, the mS could help. q.v. a query mS maps to XPath queries & presents.

  • DCAE DES - Will be presented at Nov 4, 2020 DCAE Call. Developed by Chinamobile team as part of KPI monitoring functionality.

  • DCAE DES - will be used for both OOF SON & E2E Network Slicing (U/C mtg Mondays)

  • DCAE DES & PM - Templates for PMs. KPI monitoring. #1 aggregate & store-fetch data & SQL query > #2 calculate, KPI, policy > #3 present to user. PMmapper. RT Data > computation. Not yet done. Generic formula. Config policy loaded. PMmapper filtering vs normalizing. Raw PM Counter Data (3GPP & VS PM) → KPIs. Network slicing team is working on this.

  • DCAE DES w/ External DBs - Can plug in external DBs? Starts with simple MongoDB. SQL templates. Presto SQL Query engine.

  • Store & Reexecute previous queries.
