1. Suppose that a certain communications protocol involves a per-packet overhead of 56 bytes for headers and framing. We send 1.5 million bytes of data using this protocol; however, one data byte is corrupted and the entire packet containing it is thus lost. Give the total number of overhead + loss bytes for packet data sizes of 1,000, 5,000, 10,000, and 20,000 bytes. Which size is optimal?
