26.3.5.6 UDP Datagram Format
Following the IP Header, a user datagram protocol header is found when the protocol
identifier has a decimal value of 17.
Following the UDP header is the payload of the datagram. The header byte order follows
the conventions given for the IP header above.
26.3.5.7 TCP Datagram Format
Following the IP Header, a TCP header is found when the protocol identifier has a decimal
value of 6.
