An IP Datagram 56,00 bytes long(including header with no options) arrives at a router which determines that the next destination has an MTU of 15,00 bytes. Answer the following questions showing your calculations and reasoning. a) Assuming that the router decides to frigment the packet into 4 fragment , for each fragment , determine a correct size , and identify the starting byte and ending byte. b) Calculate the fragmentation offset for each fragment. c) The total number of bytes from all 4 fragments leaving the router should be greater than the inital datagram size that arrived.Explain why this is so
