Link Discovery problem

Hello,

I have done all the NG-SDN exercises and all of them work. However, I have problems when using wider topologies. In particular, link discovery doesn't work well if the mininet topology consists of more than 10 nodes. I have created a the topo.py file defining the new topology and a netcfg.json file defines the grpc address and port associated with each stratum device (for example, "managementAddress": "grpc://mininet:50001?device_id=1" to "managementAddress": "grpc://mininet:50016?device_id=1"), and finally I have modified the docker-compose.yml file to include the required values in the "ports" field (ports: -"50001-50001" -"50002-50002" ... to -"50016-50016" ).

Using onos cli, it can be checked that all the devices are discovered, but not all the links. I always use the same files but, depending on the execution, sometimes certains links are not discovered and sometimes others.

Are there any limitation on the network size? I would appreciate any help.

Thanks a lot

Hi! I also had trouble in creating wider topologies. I found that the devices location in onos didn't match the ones in mininet. Do you have the same problem? Could you please show me your topology creation process? It will help me a lot. Thank you!
