Agenda & Notes:

• Introductions
• Define what role each member will play (architect, developer, tester, etc,,,)
• Refer to  "APPC Team for Release 1"section below
• Decide on date/time for weekly meeting
• Proposed: Wed @ 11AM EST -
• Decision: go for this slot and adjust if it doesn't work
• Determine agenda for this weekly meeting
• Reuben and Ave to re-align on APPC Project proposal as identified on the wiki.
• Review release schedule
• https://wiki.onap.org/display/DW/Release+Planning
• Upcoming Milestone - M1, due 6/29
• Must have Epics/Stories defined for release 1.
• Start discussing potential scope for release 1
• Scope: https://wiki.onap.org/pages/viewpage.action?pageId=3246996
• Use Cases: Any impact?
• vCPE: https://wiki.onap.org/display/DW/Use+Case%3A+Residential+Broadband+vCPE?src=contextnavpagetreemode
• Use case still under discussion
• Here is an opportunity to show how to manage components that are not MANO compliant
• Need to define an alternative with APPC
• VoLTE: https://wiki.onap.org/pages/viewpage.action?pageId=3246140&src=contextnavpagetreemode
• As currently defined, there is no APPC impact.
• APPC and VF-C both are part of architecture; currently no plans to separate
• VoLTE is where APPC is most experienced
• vIMS & vEPC are ETSI MANO devices; we need a plan on how to handle MANO devices
• VF-C exposes a NB API
• Chef and Ansible adapters got merged this weekend; opens up the SB side

Decisions/Working agreements:

• Weekly call to be held on Wednesdays at 11AM EST initially; will adjust as needed if this time is problematic. With folks on Pacific Coast (PST), France, and Belgium, and India, this is the most accommodating for majority.
• Participant must participate as a contributor and gain some expertise before they can be nominated for Committer status.
  • Per input from Marcus, this does not appear to be aligned with ONAP TSC charter, so I'm scratching this.
    

Action Items

• Schedule call for Wed., setup zoom invite.
• For this Wednesday's team call, 6/21/17, agenda will be to realign on the APPC project proposal. Reuben and Avi to present.
• Owner: Randa/Catherine
• Status: Done.
• Schedule a call for Thurs, 6/22/17.
• Agenda for this call: Paul will present current capabilities of APPC..
• Owner; Randa
• Status: Done, call scheduled for 6/22/17 at 12PM EST for APPC Project team.
• Follow-up with Piyush, Marcus, Alexis, Rashmi on participation.
• Owner: Randa/Catherine
• Status: In-Progress

APPC Team for Release 1

6/21/17 APPC Project Weekly Minutes

Agenda

• Reviewing the APPC Project scope to realign on what was proposed/approved: https://wiki.onap.org/pages/viewpage.action?pageId=3246996
• Presented by Reuben Klein and Avi Chapnick, who were the primary authors of this proposal initially.

Plan for next meeting

• There were a lot of questions at this meeting about what APPC was, how it fit into the overall architecture, so plan for next week is to provide knowledge sharing session on current capabilities of APPC.

Notes around today's discussion.

• Today there are two Application Controller designs
  • VF-C

• Collection of OPEN-O orchestrators, more dependent on VNFC for doing many of its actions.
• APPC
  • Manages lifecycle actions through a set of commands, you have a model and inventory VNF/VNFC instances; the approach is to support different flavors of VNFs without having to ask for vendor support (no need to provide a VNF manager, just provide a model), utilize Nefconf, Chef, Ansible plug-ins.
  • When we say "model" in context of APP-C, what are we talking about?
    • APPC is agnostic, APPC is all about how we can generalize VNF management - the concept of APPC.
    • We want to take all of the management capabilities and express them as a model and policy.
    • MANO looks at each vendor system in isolation, we want to build an inter-vendor solution, build models on demand.
    • We have a series of Yang for components and some on services
      • SDC provides TOSCA model for dependency order. We want to add to these capabilities.
    • We want to get to a common set of APIs so that operations teams don't have to worry about the underlying mechanism.
    • APPC does not instantiate, this is done by SO. Once instantiated, APPC's job is to configure, manage state, and respond to actions triggered by Policy.  Such as the case of closed loop corrective actions (Eg. Restart).  APPC manages the lifecycle of VNFs.
    • Collectors are not in the scope of APPC. ONAP is an integrated system, APPC plugs into this overall system.  DCAE local is doing the analytics collection.
    • The concept of APPC is entirely independent of the client that calls it on the NB side; APPC is to create implementation of LCM and not assume.
    • There is an VNF SDK & modeling project, how do we connect with those projects? How are the dots connected? Further investigation needed.
• What would participants like to hear about in these weekly meetings.
  
  • Participants would like to learn more about APPC and how it interacts with other parts of the stack.
  • Interactions with APPC and instantiation with respect to Policy.
  • Use cases around service chaining.

06/28/17 - APPC Project Weekly Minutes

Agenda

• Review Resources updated here: https://wiki.onap.org/display/DW/Resources+and+Repositories 
• Review Release Schedule - make sure all are aligned
• Key milestones to keep in mind can be found here: https://wiki.onap.org/display/DW/Release+Planning

• Logistics/housekeeping
• Jira APPC project & board
• https://jira.onap.org/secure/RapidBoard.jspa?rapidView=17&view=planning.nodetail&epics=visible
• Communication:
• Email: use onap-discuss with [appc] tag in subject line
• Any other options ?
• Miinutes will be kept here:
• https://wiki.onap.org/display/DW/APPC+Meeting+Minutes
• Review Use cases & Brainstorm on what we want to achieve in Release 1
• Use Case: VoLTE:  https://wiki.onap.org/pages/viewpage.action?pageId=6593603
• Use Case: Residentail Broadband vCPE: https://wiki.onap.org/pages/viewpage.action?pageId=3246168
• Use Case: vFW / vDNS: https://wiki.onap.org/pages/viewpage.action?pageId=3246170
• Other topics/dependencies
• MultiVIM
• OOM/Common Controller SDK  ?
• SDC ?

Action Items:

• Alex to get details on VNF planned for vCPE use case
• Setup call with SO & APPC teams…
• Setup call with MutiVIM team - lead Xinhui Li

Notes:

• Resources review
• Have not heard back from 1 committer; will leave him on list for now
• Sharon Chisholm will be contributing to the project, focusing on resiliency
• VoLTE Use Case
• Current approved use case does not include APPC
• There is an alternate VoLTE use case that was proposed by Gil Bullard, but marked Obsoleted.
• What are we committing for Release 1?
• Need to work out the combined architecture
• vCPE Use Case
• APPC will be contributing to the vCPE use case in the closed loop flow for VM Restart; important to note that this is VM level and not VNF level restart
• Some of the VMs selected are optimized for hardware platforms
• Some of the VNFs being used are coming from Intel, need to see if they are compatible with APPC [however, if we stiff to VM level Restart, this is not an issue for vCPE use case]
• Can use Ansible, need Ansible server and write the playbook…
• vFW / vDN Use Case
• Regression test; need to ensure these work with all the new added code..
• MultiVIM
• Separate session to be scheduled to discuss CDP-PAL

07/03/17 - APPC/SDC Discussions

Agenda

• Review of Residential Broadband vCPE with the SDC team

Attendees: Eric Lebeau, Michael Lando, Eden Rozin, Catherine Lefèvre

Key Notes

• Review of "Onboarding of infrastructure VNFs" flow
• There is already an existing APPC/SDC interface but the content is not yet really used by APPC
• The content is based on TOSCA format
• Another integration point is foreseen between SDC & APPC as part of ONAP R1:
  Currently artifacts are uploaded manually. The goal is to upload automatically.

Action Items:

• Eden will review this flow (DCAE Telemetry) as well as the second integration point (upload automatically the artifacts) with Hector Anapan by 7/10.
