Web[citation needed] Forouzan and Kurose use network-layer instead of internet-layer in their TCP/IP model definition. These differences between models often lead to pointless and endless debates. There is no TCP or UDP port number associated with ICMP packets as these numbers are associated with the transport layer above. Datagram structure
In the early 1970s, the term datagram was created by combining the words data and telegram by the CCITT rapporteur on packet switching, Halvor Bothner-By.
