Overview
DCAE Controller/Platform offers generic functions for service component (MS) to leverage under DCAE umbrella. The platform simplifies and address common requirements, thereby facilitating easier integration for DCAE mS in standardized way. With focus on Security, DCAE platform was enhanced in Dublin release to include DMaaP cloudify plugin, this was an essential first step toward enabling dynamic feed/topic creation support.
The DMaaP plugin interfaces with Dmaap-DBCL component to carry out this request and provision AAF based topic (on Message router) / feed (on Data-Router). Through this feature, all data-flow between DCAE MS can be supported via secure topic (MR) and feed (DR), which is an ONAP security priority.
Design/Architecture
- Onboarding (design)
- The mS owner identifies the input and output stream in spec file. The actual topic/feed and access credentials are
- Runtime
- Plugins (Dmaap and K8SPlugin)
- These are cloudify plugins bootstrapped into DCAE Cloudify Manager during platform instantiation. The plugins provides interface/function to implement specific function. The plugins are referenced based on node type in the blueprint (deployment artifact for DCAE MS).
- DMaap Bus Controller (DBCL)
- DMaap Bus Controller provides API to serve new feed and topic creation requests
- ConfigBindingService
- DCAE Platform Component providing standardized API for DCAE Microservice to retrieve configuration including Dmaap topic/feed configuration dynamically provisioned.
- Consul KV
- Key-Value store where all service component configuration are stored during deployment.
- Plugins (Dmaap and K8SPlugin)

EL-Alto Usecase
The 5G Bulk PM components, namely DataFile Collector and PM-Mapper were deployed using Dmaap Plugin integration for El-Alto.
<usecase reference to be added>
DataFile Collector : Subscribe from MR topic, publish files into DR feed
PM-Mapper : Subscribes from DR Feed; publish into MR topic
Demo
Scope

- Deployment for DFC (via dashboard)
- Validation of new feed created
- Review blueprint configuration for PM-Mapper
- Deployment of PM-Mapper (via dashboard)
- Validation of new feed/topic created
- Sample data flow
