- virtuallynathan 11y agoThis is true, but I can't imagine Google/Amazon/Microsoft are using Cisco/Juniper routers at every level of their network.
- stephengillie 11y agoHosts play a big part of SDN in that they support the dvswitches along with guest VMs. Not everything is a Cisco/Juniper. Switching hardware is still common in TOR and egress.
