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:

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.

Database

  • 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
