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[..]

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