OSC Project roundup:

NONRTRIC (John Keeney)

• Looking at how to deploy & LCM Apps in OSC E
  
  • Based on work in ONAP: https://wiki.onap.org/display/DW/TOSCA+Defined+Control+Loops%3A+Architecture+and+Design
    • While this is based on older work on ONAP Control Loops/Clamp - it is basically a full re-architect & build.
  • Still at a very early stage, not yet ready to present / demo ... Hope to demo/present at upcoming RSAC meetings a few weeks.
  • Current prototyping going very well - using the OSC D "Link Monitor" Apps as requirements drivers & "pipe cleaner".
• A1 Policy Functions in ONAP
  
  • Issue with Jenkins Job - fixed now.
  • Work continues on A1 Adapter & A1 Policy Management Service extensions.

OAM (Martin Skorupski)

ONAP SMO deployment options (Christophe Closset (AT&T) & Amar Kapadia (AARNA))

• Last week's meeting minutes & recording: https://wiki.onap.org/display/Meetings/2021-07-16+Meeting+notes Meeting series continues on Friday this week: https://wiki.onap.org/pages/viewpage.action?pageId=103422272
• Github: https://github.com/gmngueko/oran-deployment - Ask @Martial for access if you want to contribute.
• John Keeney Working with Trishan de Lanerolle to create a ticket to expose OSC Helm charts in OSC nexus. Will probably need further discussion over the next while - including all PTLs.
  • Need to ensure we have a common approach across projects for releasing & formulating charts.
  • Can start with just those in it/dep repo - but we want to move beyond this, where projects have better control over their charts rather than just the integrated versions in it/dep
  • Martin Skorupski & team have a set of helm charts used in OSC Lab deployment (in OAM repo) which should also be made available.

Service Exposure / Gateway in OSC

• Kamel Idir What is the role / difference between NONRTRIC Service Gateway & Service exposure functions:: See Release D (sect "Non-RT-RIC (Spring Cloud) Service Gateway" & "Non-RT-RIC (Kong) Service Exposure Prototyping"))?
  • John Keeney Gateway started as function between Control Panel & A1 Services, but evolved into a generic gateway function for Apps/ControlPanel to access multiple NonRTRIC/SMO service. In parallel we experimented with Kong as an alternative basis to achieve similar functionality.
    Later we envision that such a Service Exposure function may be useful for the R1 interface once it becomes better defined - to support rApps to safely expose their functionality to other rApps, and for rApps to safely access underlying SMO&NonRTRIC platform functions. But it is still too early to certain what R1 will be once standardized ....
    For R1 will likely need more support functions than Kong can provide ... but hopefully these requirements will become clearer soon.
