Snoop: Performance
nno difference in very low error rate environment (bit
error rate < 5x10-7)
nfor higher bit error rates, Snoop outperforms regular
TCP by a factor of 1 to 20, depending on the
bit error rate (the higher, the better
Snoop’s relative performance)
neven when every other packet was dropped over the
wireless link, Snoop still allowed for
progress in transmission, while regular TCP
came to a grinding halt
nSnoop provides high and consistent throughput, regular
TCP triggers congestion control often,
which leads to periods of no transmission
and very uneven rate of progress
