Source IP address Destination IP address Source port number Destination port number UDP message length UDP checksum

192.168.1.1 192.168.1.3 51786 69 25 0x72213

f) UDP datagram is complete by checking if computed value of checksum received is similar to checksum sent.

Reflection: Difference between the way TCP and UDP manage communication: TCP:  

need extra control over communication channel slower transfer speed

UDP:   

less overhead, less control upper layer protocol supply acknowledgement control faster transfer speed...
