  • API Incoming Dependencies

List the API this project is expecting from other projects.
Prior to Release Planning review, Team Leads must agreed on the date by which the API will be fully defined. The API Delivery date must not be later than the release API Freeze date.

Prior to the delivery date, it is a good practice to organize an API review with the API consumers.

Other Information

  • Vendor Neutral

If this project is coming from an existing proprietary codebase, ensure that all proprietary trademarks, logos, product names, etc. have been removed. All ONAP deliverables must comply with this rule and be agnostic of any proprietary symbols.

  • Free and Open Source Software

FOSS activities are critical to the delivery of the whole ONAP initiative. The information may not be fully available at Release Planning, however to avoid late refactoring, it is critical to accomplish this task as early as possible.
List all third party Free and Open Source Software used within the release and provide License type (BSD, MIT, Apache, GNU GPL,... ).
In the case non Apache License are found inform immediately the TSC and the Release Manager and document your reasoning on why you believe we can use a non Apache version 2 license.

Each project must edit its project table available at Project FOSS.


Charter Compliance

The project team comply with the ONAP Charter.

  1. Hi, I read a bunch of docs on DMaaP and watched a presentation on Message Router architecture and usage. I've noticed that DME2 is shown as a part of MR architecture. Although DME2 description seems to imply it is only needed if a remote communication needs to be supported across data centers perhaps... So is DME2 a required component of DMaaP/MR ? If so, Is it packaged within MR docker container or does it have to be deployed separately? Thanks a lot, Jane F.

  2. Frieder, We are not using the DME2  in the MR now. For deploying the MR, one need to deploy only Kafka and Zookeeper

    1. Thanks Sunil. Then the design diagram on the MR Architecture page is misleading as it shows DME2 clearly. I also have a related question - as I understand Beijing now has Data Bus Controller which sits on top of MR and DR and ultimately provides a kind of wrapper API. The attached picture says that Bus Controller saves data into DCAE Persistent Storage. This sounds very strange to me. Does it mean that DMaaP can't be used stand-alone and requires DCAE always?? I'd appreciate a clarification on this. Thanks, Jane F.

  3. DMaaP MR can be used without the Bus Controller. Bus Controller is used to provision the AAF permissions and creating the topic etc.

    1. To add a few more words:  

      • in Beijing, the DMaaP transport service available is the Message Router (MR - for messages).  A future release should also offer Data Router (DR - for files).  
      • app usage of these services is focused on the pub/sub API, but before that can be attempted, the service needs to be provisioned.  
      • The Bus Controller API is provided to apps so they don't need to learn multiple DMaaP provisioning APIs and also to unify the authorization model.
        • The data persistence represented is only for provisioning data.
        • The value of this API may be unclear in a Release before geo-redundancy is supported, DR is included, and full AAF integration is understood.  But apps will be better positioned for these future complexities by using the Bus Controller API to provision now.
      1. Thanks Dominic. So are you saying DR is not in Beijing release? I was under the impression it is.

        If understand you correctly you are saying messages are not really persisted, just the topics info is ... Note, in the Bus Controller description I saw that data persistence is optional, meaning topics are stored in a cache of some kind then?

        1. re DR in Beijing:  AFAIK, DR was descoped.

          re prov data persistence in Bus Controller: correct, when persistence is not configured, prov data is stored in a memory cache which would be lost if the container is restarted.  This is handy for when the overhead of Postgres install and config is an issue.
