Limitations of The Principle
The most important limitation of the end-to-end principle is that its basic conclusion – put functions in the application end points rather than the intermediary nodes – is not trivial to operationalize. Specifically:
- it assumes a notion of distinct application end points as opposed to intermediary nodes that makes little sense when considering the structure of distributed applications;
- it assumes a dichotomy between non-application-specific and application-specific functions (the former to be part of the operations between application end points and the latter to be implemented by the application end points themselves) while arguably no function to be performed in a network is fully orthogonal to all possible application needs;
- it remains silent on functions that may not be implemented "completely and correctly" in the application end points and places no upper bound on the amount of application specific functions that may be placed with intermediary nodes on grounds of performancy considerations, economic trade-offs, etc.

Famous quotes containing the words limitations of, limitations and/or principle:
“The limitations of pleasure cannot be overcome by more pleasure.”
—Mason Cooley (b. 1927)
“Growing up means letting go of the dearest megalomaniacal dreams of our childhood. Growing up means knowing they can’t be fulfilled. Growing up means gaining the wisdom and skills to get what we want within the limitations imposed by reality—a reality which consists of diminished powers, restricted freedoms and, with the people we love, imperfect connections.”
—Judith Viorst (20th century)
“It were as wise to cast a violet into a crucible that you might discover the formal principle of its colour and odour, as seek to transfuse from one language into another the creations of a poet. The plant must spring again from its seed, or it will bear no flower—and this is the burthen of the curse of Babel.”
—Percy Bysshe Shelley (1792–1822)
