SD-Wan question

Hello,

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?

also, the reason why some of these locations WAN speeds are so low is because there is not much ISP providers in the area that provide anything faster the 10Mb or lower. Some of these buildings are in the middle of no where

Ok, Could I have different provider for internet and different provider for SD-WAN and have that work together?

Mike Smith

Absolutely. I recommend it.

In terms of provider selection, each offer different advantages, such as IP Addresses from their network, managed security, etc.

thanks, so just to clarify, if I have 5Mb connections (very slow) back to HQ, The only advantage of adding SD-WAN on top is that it will improve latency, packet loss and jitter thus increasing the speed BUT not actually increase the speed of the circuit, correct?

Mike Smith

Correct. It will only increase the actual bandwidth if you add a second circuit for it to load balance/aggregate.
