Wrong.
See below how it is stated.

W.r.t. multihoming, neither follows the end to end principle of:
http://groups.csail.mit.edu/ana/Publications/PubPDFs/End-to-End%20Arguments%20in%20System%20Design.pdf
The function in question can completely and correctly be
implemented only with the knowledge and help of the
application standing at the endpoints of the communication
system. Therefore, providing that questioned function as a
feature of the communication system itself is not possible.
(Sometimes an incomplete version of the function provided
by the communication system may be useful as a performance
enhancement.)
