Some use TCP Vegas while others use TCP CUBIC and TCP BBR. Each server is managed by a different department and it is impossible to change these congestion control schemes.

Fairness

During a management meeting, on department head complained about the low performance of his fileserver. He did an experiment with a colleague who works from home. This colleague tried to download a large file from the server of department A and another file of similar size from department B. The A server provides a throughput of more than 65 Mbps while server B could only reach 30 Mbps.

B's department head is unhappy with this result and claims that the network was tuned to better serve department A than department B. Describe the techniques that you would use to solve problem in one paragraph.
