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
