Just for understanding: What would be the reason to have the
multiplexing point above the transport protocols?

At the network layer, you gain, e.g., mobility support through loc/id
split, and thus a certain flexibility during the life-time of a
communication. The transport protocol or service address (port) cannot
change during the communication. Initial flexible selection of a
transport protocol or a service discovery, however, is not affected
(i.e. can still be done).
