Supposed datagrams are limited to 1600 bytes (including header, with header size = 40) between host A and destination host B.
Assuming a 20-byte IP header; further assume that the data is carried in TCP segments, with each TCP segment also having 20 bytes of header.
How many datagrams would be required to send a MPEG4 consisting of 20 million bytes. Show your work. Describe the size of the fragment and the size of the last fragment.
