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. While the word was new, the concept had already a long history. In 1962, Paul Baran described, in a RAND Corporation report, a hypothetical military network having to resist a nuclear attack. Small standardized "message blocks", bearing source and destinatio… WebProtocol data units of the OSI model are: [1] The Layer 4: transport layer PDU is the segment or the datagram. The Layer 3: network layer PDU is the packet. The Layer 2: data link layer PDU is the frame. The Layer 1: physical layer PDU is the bit or, more generally, symbol.

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 WebData-Link Layer--Framing Takes Place Data-link layer protocols, such as PPP, format the IP datagram into a frame. They attach a third header and a footer to "frame" the datagram. Then the data-link layer passes the frame to the physical layer.
