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 motion picture made in Hollywood, if it is to create art at all, must do so within such strangling limitations of subject and treatment that it is a blind wonder it ever achieves any distinction beyond the purely mechanical slickness of a glass and chromium bathroom.”
—Raymond Chandler (1888–1959)
“To note an artist’s limitations is but to define his talent. A reporter can write equally well about everything that is presented to his view, but a creative writer can do his best only with what lies within the range and character of his deepest sympathies.”
—Willa Cather (1876–1947)
“Why does philosophy use concepts and why does faith use symbols if both try to express the same ultimate? The answer, of course, is that the relation to the ultimate is not the same in each case. The philosophical relation is in principle a detached description of the basic structure in which the ultimate manifests itself. The relation of faith is in principle an involved expression of concern about the meaning of the ultimate for the faithful.”
—Paul Tillich (1886–1965)
