1) Technical aspects and relevance to upstream projects

Ryota created new Wiki page to start technical discussions on the "Doctor" Project. He presented his document:

  • Use cases section includes short description of the Auto Healing, Safe Switching and VM retirement use cases.
  • Requirement section contains an initial list of features and items to be addressed.
  • Architecture section contains a description of the architecture functional blocks and one example implementation in OpenStack.
  • It was clarified that the resource owner may be VNFM or NFVO. What is important is to have the feature in the northbound interface.
  • Discussion around adequate pub/sub model for fault notification. Palani agreed to support this activity.
  • Ryota explained that during the OpenStack Paris Summit, there were some discussions on letting Monitor(s)/Inspector update resource state information (e.g. VM state in Nova). This idea was accepted by Nova team.
  • It was also agreed to have the Monitor(s) / Inspector outside of OpenStack / VIM (easier to extend these functional blocks if outside of OpenStack when new types of NFVI faults need to be reported to the VIM).
  • It was clarified that Heat is emulator for VNFM/NFVO and interface between Heat and Nova shall be used for corrective actions on VMs.
  • All are welcomed to edit Wiki page, review/modify/add new use cases and notify Ryota of changes to this page.
  • All are welcomed to draw other architecture figures.

2) Resources available and necessary for this project

  • Initial list of developers / committers: Ryota, Carlos, Tomi, Zhangyu, Palani
  • Initial list of contributors to specs / documentation: Ashiq, Uli, Serge, Dirk

3) Scoping and scheduling (what features to be realized in what time frame)

Important milestones:

  • OpenStack Gap Analysis by end Nov 2014
  • First Spec ready by mid Dec 2014. Second / Revised Spec ready by mid / end Jan 2015
  • Blueprints submitted to OpenStack by end Mar 2015 (L-release)
  • Depending on the progress of the work, blueprints may already be submitted in Jan 2015 (Kilo-release)

4) AOB

  • It was decided to have weekly meetings.
  • Because of national holiday in Japan on Nov 24, next meeting is planned on Dec 1 (Mon) at 14:00 UTC

5) Action Items

  • Ashiq to report on what kind of faults need to be detected from operational point of view
  • Ashiq to check timeline of other upstream projects (e.g. KVM, ODL)
  • Palani to report on relevant pub/sub Open Source project
