TCP window size recommendations

Table 16 through
WAN environments. These tables are organized by typical link speed.
NOTE:
The TCP window size recommendations listed in
networks (0.0012% average packet-loss ratio over 24 hours). For higher-loss, longer-latency networks,
you should reduce the recommended window size and scaling factor by one setting to compensate
for the increased number of packet retransmissions.
