1. Architecture

This architecture depicts a standalone PCI micro-service. When this is moved to DCAE, it may undergo some adaptations, for e.g., the interfaces have to be adapted appropriately.


                     


With reference to the above architecture:

1.1. Core Logic

This is composed of a Main Thread and one or more Child Threads. The Main Thread is responsible for spawning and terminating the Child Threads, this is described in the sections below.

1.2. Database

This is a PostgreSQL DB, and is intended to persist information such as the following:

  • PCI-Handler MS Config information (e.g., thresholds, timer values, OOF algorithm name, etc.)
  • Pre-processing results and other related information (e.g., neighbor list)
  • Buffered notifications (i.e., notifications not yet processed at all)
  • State information
  • Association between pnf-name and CellId

1.3. DMaaP Client

This is responsible for registering with the DMaaP client for the DMaaP notifications from SDN-R, and to Policy.
