Doctor platform components and features¶
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.
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
Note
Doctor Inspector and Monitor are sample implementation for reference.
