How to monitor Linux network quality for different directions

The legends have two problems. They are not believed in or they are believed in too much.

Sometimes we might need to know if the network connection between our host and other peers is good enough. The main quality attributes of the network connection are badwidth (quite easy to explore) and the packet loss rate (quite difficult to explore). Of course we can monitor the overall TCP retransmit rate (for example using something like netstat -s | grep -i retrans), build the graph and stare at it. But we'll never know which direction is loosing the packets and where is the problem itself.
I have not found the ready-to-use solution and created my own. You can see the results right here on the screenshot.
