Design a network based on SDN with ONOS and Mininet.

Hello experts, I am looking for a person who is familiar with SDN, ONOS controller, and Mininet as I need to deploy 30 Openflow Switches roughly to simulate a service operator (ISP) network. This simulated SDN network should have the following: - The topology must have hosts, switches and routers. - Network topology based on the 3-layer model (access, distribution and core), or failing that, one that you recommend, example: Leaf Spine - Execute scripts (based on JSON or other) from the SDN controller so that all or a group of switches self-provision with certain configurations. - You must have voice, data and management vlans. - My switches must be configured from the controller and must be configured with IPs, vlans, static routing, routing protocols, intervlan communication, QoS, etc. - If a host has the data vlan assigned, the host must have connectivity exclusively to the IP of the switch that gives the Internet access. Note: Actually, in the simulation, connectivity to the internet from the host (client) does not have to be demonstrated, I simply want the host to have a connection with its gateway. - If a host has 2 vlans assigned (voice and data), the host must have connectivity to the IP of the switches that have that vlan labeled. - ONOS controller redundancy (active - passive). In case controller A fails, controller B should go into operation. Basically these are the specifics, my goal for this is to show how fast it is to self-provision an SDN-based network that has numerous switches / routers. Thanks.
