Hi everyone,
I noticed that there's already a gRPC southbound available for interacting with devices that expose a gRPC interface. However, I couldn't find any examples demonstrating its usage. I have a few questions:
- How can we enable the gRPC protocol?
- What's the process for connecting a device to ONOS using the gRPC protocol?
- How can we retrieve the network topology, links, and other relevant information using gRPC?
- Lastly, how do we push a rule to a device using gRPC?
Any guidance or examples you can provide would be greatly appreciated.
Best regards, Sofiane

Hi Sofiane,
You can find some examples here https://github.com/opennetworkinglab/ngsdn-tutorial, this tutorial should give you the answers to your questions.
Best,
Davide

Hi David;
Thanks for the answer but what im trying to do is not related to p4runtime but grpc protocol ?

Hi Sofiane.
P4Runtime, like gNMI and gNOI, is based on grpc so you can take
advantage of this in order to understand how implements your
solution.

Hello everyone,
I'm trying to deploy a gRPC application on top of ONOS, but I'm encountering some errors:
