DRAFT  - as of 3/1 

  1. Project Overview

    DCAE is platform includes number of components collectively fulfilling the role of Data Collection, Analytics, and Events generation for ONAP.  The architecture of DCAE targets flexible, plug-able, micros-service oriented, model based component deployment and service composition. DCAE also support multi-site collection and analytics operations which are essential for large ONAP deployments. 

    DCAE components generally fall into two categories: DCAE Platform Components and DCAE Services Components.

    DCAE Platform refers the set of controller components which manages the deployment and LCM of the DCAE service components which include all the collectors, analytics and event processor MS. 

     

  2. New component capabilities for Dublin, i.e. the functional enhancements

    Following are new components introduced for Dublin

    Collectors

              RESTConf collector            

    Event Processors

              VES/Universal Mapper 
              3gpp PM-Mapper  
              BBS Event processor
              DL Handlers (POC)

    Analytics/RCA


             SON-Handler (former PCI-Handler)
             Heartbeat (STRETCH GOAL) 
             TCA-Gen2  (STRETCH GOAL)

     

  3. New or modified interfaces

      4.   <include arc diagram>

  4. Interface naming

                 <refer m1>

  5. Reference to the interfaces


  6. What are the system limits

    Relies on k8s for loadbalancing and scaling. DCAE platform handles the control flow and do not carry the data/event; DCAE service components can be scaled and support state management.
    Cloudify is 3rd party product; HA feature on community version will be available later in 2019; will be incorporated for E release

  7. Involved use cases, architectural capabilities or functional requirements
