1. Doctor Platform


1.1. Features

Doctor platform, as of Brahmaputra release, provides the two features:

  • Immediate Notification
  • Consistent resource state awareness (Compute)

These features enable high availability of Network Services on top of the virtualized infrastructure. Immediate notification allows VNF managers (VNFM) to process recovery actions promptly once a failure has occurred. Consistency of resource state is necessary to properly execute recovery actions properly in the VIM.

1.2. Components

Doctor platform, as of Brahmaputra release, consists of the following components:

  • OpenStack Compute (Nova)
  • OpenStack Telemetry (Ceilometer)
  • OpenStack Alarming (Aodh)
  • Doctor Inspector
  • Doctor Monitor


Doctor Inspector and Monitor are sample implementation for reference.

You can see an overview of the Doctor platform and how components interact in Fig. 1.1.
