Protocol layering is an effective design principle, which simplifies development of complex communication systems. In theory, protocol designers have to deal with only two interfaces—one to the protocol layer above, and one to the protocol layer below. If the layering principle is strictly followed, however, certain optimization opportunities can be lost. In practice, popular protocols have been designed making some implicit assumptions about other layers in the protocol stack. Most of these assumptions have not been written down explicitly, but become apparent with recent changes in technology.
