TCP/IP Model in Practice

VXLAN - tunnels - such as GRE - or recursive encapsulations - such as MAC-in-MAC. These protocols have evolved with no organization to solve individual use cases as they appeared, invalidating the original architectural model and increasing the complexity of networks, as seen in Figure 2.

A technical diagram contrasts the neat, layered TCP/IP reference model in theory with the messy practical model, where many tunneling and encapsulation technologies are stacked across layers. The joke is that real-world networking has become absurdly complicated because each new use case adds another protocol or workaround.
