User Datagram Protocol
6. a. In cases where reliability is not of primary importance, UDP would make a good transport protocol. Give examples of specific cases;b. Give two examples of specific cases where UDP will not be a good transport protocol to send data;
7. Show the entries for the header of a UDP user datagram that carries a message from a TFTP client to a TFTP server. Fill the check sum with 0s. Choose an appropriate ephemeral port number and the correct well-known port number. The length of data is 40 bytes. Show the UDP packet using the format in figure 14.2.
8. a. A client uses UDP to send data to a server. The data length is 16 bytes. Calculate the efficiency of this transmission at the UDP level (ratio of useful bytes to total bytes).
b. Redo (a), calculating the efficiency of transmission at the IP level. Assume no options for the IP header.
