Some more notes... It's been very late when writing this.

In general TCP is quite capable
of recovering from lots of errors, but it's busy with itself for this
purpose, which leaves less capacity for its payload. IP does not correct
errors, only detects (checksums). This leaves possible error correction
to layer 2 and 1.
Of course the application has to take care of errors. If some errors
survive the application has to cope. Some do not care at all, like video
and audio streams: If data is lost, no retransmission is tried. The
human brain has to interpolate missing information and thus do the error
correction.
In layer 2 we have a mixture of Ethernet and a back
off algorithm[..]

AFAICS check for successful transmission is done.

Of course I meant "_No_ check for successful transmission is done."
