TCP/IP question | TimingGuys.com

Hi. I confuse with my report question. it say "Suppose that the TCP entity receive 1.5 megabytes file from the application layer. It is understood that some overhead will incur from segmentaion of the file onto packet-sized units.If the TCP and IP overhead equals 40 bytes what should be the size of one data unit in order to achieve 2.8% (approx) overhead " can anyone explain this question and show me the way to solve it?

1429 bytes. Since this is very close to the MSS it will be nearly impossible to achieve this level of efficiency. It's a theoretical number likely to never be achieved in practice. Unless you're dealing with raw sockets you shouldn't care what the packet sizes are. Simply send the data to the socket and let the stack worry about segmentation.

these things confuses me as well.
