Unformatted text preview: port number 69 for its source socket address and the IP address 126.96.36.199, com-bined with an ephemeral port number as the destination socket address. 9. Since the length of a datagram must be contained in a 2 byte field, the maximum size of a UDP datagram is 65,535 bytes (header plus data). However, given that the IP layer must also store the total length of the packet in a 2 byte field, the maxi-mum length would be 20 bytes less than this, or 65,515 bytes, to leave room for the IP header. The implementation may impose a smaller limit than this. 11. The largest amount of process data that can be encapsulated in a UDP datagram is 65,507 bytes. (65,535 minus 8 bytes for the UDP header minus 20 bytes for the IP header). The implementation may impose a smaller limit than this. 13. 16 bytes of data / 24 bytes of total length = 0.666 15. 16 bytes of data / 72 byte minimum frame size = 0.222...
