Page History

The user triggers a configuration, which will be forwarded to the O-RAN components. The flow is successfully passed when the corresponding VES message is available on DMaaP and can be processed by any other ONAP components.

Note: The VES notification syntax for a new ves-domain "cmNotify" is currently not available (state: 2019-11-21).

Initial configuration read from C&PS

After service design the user stores the initail initial configuration of the xNF's within C&PS.
