2. Suppose that a certain communications protocol involves a per-packet overhead of 50

bytes for headers. We send 1 million bytes of data using this protocol; however, one data

byte is corrupted and the entire packet containing it is thus lost. There are 3 options for

packet size (header+ payload): 1000, 10000 and 20000 bytes. Which of these sizes is

optimal (i.e., minimum overhead)? (Hints: lost packet needs to be retransmitted)
