b) Consider the following diagram. A datagram of 4,020 bytes (20 bytes of IP header plus 4,000 bytes of IP payload) arrives at a router and must be forwarded to a link with an MTU of 1,500 bytes. The diagram shows three fragments. Show the sizes of the fragments (in bytes) along with the offset values associated with each fragment with a chart. Explain how it is done with your own words.
