John R -

thanks for the horror story regarding chaosnet; Jack Haverty has similar
stories to tell about flaky hardware whose failure was masked by the
simple but essential end/end checksums protectingTCP and IP packets.
The big lesson learned in the case Jack tells about is that we should have
been reporting the failure/retransmission statistics somewhere; as it was,
we went on for 6 months without realizing we had bad crosstalk/interference
in cabling under the floor...
