[e2e] How do we deal with mobile networks?

I received some pointers to RS codes and similar on application layer.

First of all: Adding redundancy to a flow on application layer increases 
the amount of data which is to be transferred and hence the flow's 
resource consumption.

Second: In the particular case of TCP, packet corruption is taken as an 
indication for congestion, so we want to avoid packet corruption even if 
the lost packet may be recovered from  surrounding packets.

Hence, for TCP, a low packet corruption rate should be provided by the 
link layer.

Do I miss something?
