Suggestion on sending out a LS:

-Chuyi: the workshop is for information, and no formal response is expected. in order to get some formal feedback, it's suggested to send LS to ETSI NFV

-Marian: could ask Thinh, and bring this to the workshop; not supporting sending the LS for now, and would like to seperate the discussion from the workshop; representing E/// and Nokia

-Chuyi: will talk to Thinh

-Fred: second the suggestion to ask for formal feedback from ETSI NFV

-Hui: people can have discussion and ask their questions freely in the workshop

Shitao's analysis on the ASD model vs ETSI VNFD:

  • suggest to make the ASD model a subset of the VNFD model
  • Image Added

Comment:

  • Zu: what's the purpose of the proposal
  • Shitao: the current proposal has several references to the ETSI NFV
  • Zu: it's personal view that the ASD model reference to ETSI NFV
  • Xu: different understanding, without the reference to ETSI NFV, the model is incomplete and missing models for virtual link, for example
  • Zu: reason for mapping the models
  • Shitao: suggest to merge with ETSI model, and the developers only need to support one model
  • Zu: how to deal with the unmatched properties
  • Shitao: they can be added as extensions of the existing models
  • Marian: ASD and ETSI are taking different approaches
  • Fred: comments on the wiki as well, think the current IM misses a lot of elements. 

    -I think that there is some confusion between the needs of the ONAP Information Model versus the Data Models used for onboarding and service/resource implementation.
    -Issues that I see with the ASD IM: Missing resource (CPU, Memory, Storage, ...) requirement information Missing L2/L3 Protocol and Address information Missing Software Image information Missing Security Rules information Missing Affinity/Anti-Affinity information Missing Scaling Information Missing Healing information Missing Service/VIP mapping information Missing configuration information Missing monitoring information Missing upgrade/downgrade information

  • Marian: IM is based on K8S API, not a good approach to duplicate the K8S models, would like to have references to the K8S models
  • Hui: it's not good to take some existing models, but just change the names
