<i>If the chance is purely random, we should expect approximately 1 in 2^16 (approximately 0.001%) of corrupt packets to not be detected. This seems small, but on one Gigabit Ethernet connection, that could be as many as 15 packets per second.</i><p>Not really.  You&#x27;d only get that many corrupt packets if you have a Gbps of traffic flowing; but as soon as you start detectably corrupting 99.999% of packets, TCP throughput is going to drop dramatically and so you&#x27;ll have fewer packets available to corrupt.
