Checksums don't make a protocol reliable.
No, but they do play an important role in some reliable protocols.
reliable protocol over another makes the windowing/retransmission
algorithms conflict in a worst-of-both-worlds kind of way.
This can't be true. While it may hold in some instances, as a
general statement it can't be right. TCP/IP behaves poorly in
situations where bit error rates are high. If the overall latency
is also high, but the high bit error rate link has low latency then
the effect of placing a reliable protocol underneath TCP/IP (especially
one that does forward error correction) on the link will, without doubt,
improve real world performance.
