when you work in the OSI model, each layer introduces an overhead. Can you calculate an overhead when I give you the protocols in terms of: this protocol is using 100Mbit/s on a 1Gbit/s interface. Its one packet each 2ms, and it runs in UDP over IPv4. How much is the total bandwidth on the 1Gbit/s interface when I just calculate the Ethernet overhead with 18bytes per Ethernet frame?
