Building SD-WAN network using gns3

I am trying to build a sdn network with off course having the network controller as the main component of the software-defined network and trying to implement that with a case study of a company that has HQ and three different branches. o basically after configuring the sdn network I am trying to get the network parameters such as the throughput, packet loss, reachability, and important information for analysis. I attached a copy of my version of the topology to describe my case study, As you can see a very simple topology, trying to test the connection between HQ and different branches, and off course, that’s all possible by limiting the bandwidth and controlling the jitter. So I am thinking of limiting the bandwidth

From HQ to branch 1: 2MB

From HQ to branch 2: 6MB

From HQ to branch 3: 10MB
