Hi students, I just Want to explain what is SD-WAN from Meraki. Imagine you want to drive with a group of 20 person from Oslo to Madrid. You have 3 different typ of cars. 1 four wheel drive Car. (5 person but not as safe) 1 Limousine (8 persons very safe car) 1 Ferrari (2 Person fast but not as safe) Now there are a lot of different roads you can take but all have different challenge. The Highway (often jammed) The Road true the Mountains (Off-road but alway free of traffic) The Small Roads true all the City's and village (the longest way) Now, you need to bring all Person as fast as Possible and as Safe as Possible from Oslo to Madrid. That's the moment you will use SD-WAN. It will measure the state of the road and how much traffic jam you have on all Roads, based on this it will select the best Car and how fast you will get from Oslo to Madrid. As you can not take all person at once, SD-WAN will calculate witch will be the best Road, Car to go back to Oslo and get the rest of the Person. I hope you just got a felling what SD-WAN is doing when you have more that one WAN connection and you want to Secure transport as much data at a time.
