Assume we have a ethernet link with an MTU of 1300 bytes, while an application want to send 5200 bytes of data. How many fragments do we transmitted ?
i would say 5, to send 5200 bytes over a link with an MTU of 1300 bytes then we need 4 fragments, 5200/1300=4 but we have the additonal overhead, IPv4 header is 20 bytes, while the UDP header is 8 bytes therefore we will have 5 fragments in total.
Am i thinking right here ?
