Catch events on ONOS REST API Applications

Question

I'm using ONOS as my SDN Controller, REST in NB and Netconf in SB. I can send data over these layers, catch response and analyse them. Now, the question is how to receive events in REST API APPs. I mean there be no need for the APPs to send request and analyse the response, if something happens it automatically be sent to NB APPs. What can I do to implement this structure? And is it possible for REST Applications to receive events?

Answer 1

I've got the answer.

ONOS has an integration named kafka which can send events to a consumer. I also added a kafka producer as a module to ONOS core that can send other events which are not supported by ONOS right now.

till this day ONOS supports LINK and DEVICE events.

good luck!
