Architecture

Image Modified

Overview

  • Will demonstrate Network Discovery Microservice and Service Decomposition Microservice
  • Relies on supporting Microservices not yet in ONAP, but we can show
    • Standardized API and provide a sense of its extensibility to support discovering of additional components
    • VM attributes from Openstack
    • How this fits into POMBA architecture
    • How this could be leveraged in other use cases

Southbound API

  • The following is the information expected from the southbound interface to network discovery
    • Examples (coming soon)
    • Mocking in SoapUI (soon)

Captures

Network Discovery Context Builder → Service Decomposition

The context builder first needs to determine what resources comprise the service undergoing auditing and so it employs Service Decomposition.

Service Decomposition → AAI

Service Decomposition needs to send a series of requests to the AAI in order to effectively mine the data source for the service instance's component resources.

Network Discovery Context Builder → Network Discovery

The context builder next needs to send multiple requests – one for each resource provided by Service Decomposition – to Network Discovery in order to obtain the values of associated attributes.

Network Discovery → AAI Enricher

For each resource passed to it, Network Discovery simply hands off the discovery work to the AAI Enricher, which utilizes addons to query live networks. (Note: Enricher is not in ONAP at this time but the responses could be mocked.)
