Doctor Platform Overview

Doctor platform components and features


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

  • Immediate Notification
  • Consistent resource state awareness (Compute/host-down)

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.


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.
