Ccna routing and Switching Complete Study Guide

Identify what is contained in the UDP header of a connectionless transmission.    The fields 

in the UDP header include only the source port, destination port, length, checksum, and 

data. The smaller number of fields as compared to the TCP header comes at the expense of 

providing none of the more advanced functions of the TCP frame.

Identify what is contained in the IP header.    The fields of an IP header include version, 

header length, priority or type of service, total length, identification, flags, fragment offset, 

time to live, protocol, header checksum, source IP address, destination IP address, options, 

and finally, data.
