SD-WAN edge and physical high-end router Are physical routers, who have different management interfaces (SNMP, NETCONF, and so on), able to speak to an SD-WAN controller? In other words, can I have an SD-WAN by establishing a specific SD-WAN controller and orchestrator with a router that has just different management interfaces? which capabilities does a router have to support, to be used as an SD-WAN edge? I took a look at MEF 70 standard and didn't really find answers to my question.

No, not generally. The router needs to provide access to its forwarding plane, e.g. using OpenFlow (which the controller needs to support as well). You cannot use configuration protocols like SNMP or NETCONF.
