As stated in the image above, the dark red is customer uploading, and the darker green is customer downloading. The key on th right does label these as Red=rx Green=tx. As the graph is created at the AAISP side, the Tx/Rx is in relation to AAISP,
The colours may vary and we even allow users to configure colours individually (useful for people with colour blindness, etc.). It is also possible for us to show graphs with only some of the fields which can make some information clearer.
