Note!
Packets will usually contain multiple protocols, so more than one protocol will be
counted for each packet. Example: In the screenshot IP has 99,17% and TCP 85,83%
(which is together much more than 100%).
Note!
A single packet can contain the same protocol more than once. In this case, the pro-
tocol is counted more than once. For example: in some tunneling configurations the IP
layer can appear twice.
