If transmission errors occur they do not manifest themselves as
corrupted data, because the transports already correct these. They do as
undelivered data, dropped connections, missed deadlines, lost integrity etc.

There is no recovery from non-delivery. You can improve situation using
redundant nodes and some sort of consensus in the scenario when some
nodes might go offline. Error correcting codes is no help at this level
of abstraction (application's OSI).
