I am trying to research this question but not getting any concrete answers. I have multiple hub locations (none MPLS) connected to HQ via DMVPN. My bandwidth circuits at those external locations varies between 5Mb up to 100,Mb. My questions is, with SD-WAN, those sites with only 5Mb, will they see performance increase? Will I be able to manage this bandwidth? Or will I be cancelling the circuit with.. let's say Comcast and get a SD-WAN provider and thus leverage the speed? Also, if thats the case, will I be signing up for certain speed with the SD-WAN provider or no?
