[Starlingx-discuss] Starlingx network requirement

[Quick Convey]

Thanks Matt peters,

Compute nodes communicate via this Data interface, right ?
*VMs* in different compute nodes also use this data interface for
communication, right ? (communication between VM in CP1 -to- VM in CP2)
*OVS* also use this data interface to make tunnel between the compute
nodes, right ?

You have mentioned that application requirements decide the required number
of ports and network topology. Applications will be running in the VM and
doesn't aware about the physical topology, right ? Could you please explain
it.

Thanks,
