Question

What is best sdwan strategy for my case below.

I have 3 internet connections with bandwidth 100,200 and 300Mbps then i want to select link with low latency. If link with 100Mbps have lowest latency then this link will be used for all users, but in one side i want to utilize the other link if this lowest link is fully utilized.
