Network Layer - Relation To TCP/IP Model

Relation To TCP/IP Model

The TCP/IP model describes the protocols used by the Internet. This model has a layer called the Internet layer, located above the link layer. In many textbooks and other secondary references the Internet layer is equated with OSI's network layer. However, this comparison is misleading as the allowed characteristics of protocols (e.g., whether they are connection-oriented or connection-less) placed into these layers are different in the two models. The Internet layer of TCP/IP is in fact only a subset of functionality of the network layer. It only describes one type of network architecture, the Internet.

In general, direct or strict comparisons between these models should be avoided, since the layering in TCP/IP is not a principal design criterion and the Internet Engineering Task Force (IETF) considers it "harmful".

    ... a worker was seldom so much annoyed by what he got as by what he got in relation to his fellow workers.
    Mary Barnett Gilson (1877–?)

    Research shows clearly that parents who have modeled nurturant, reassuring responses to infants’ fears and distress by soothing words and stroking gentleness have toddlers who already can stroke a crying child’s hair. Toddlers whose special adults model kindliness will even pick up a cookie dropped from a peer’s high chair and return it to the crying peer rather than eat it themselves!
    Alice Sterling Honig (20th century)
