TCP window size recommendations
Table 4 (page 28) through Table 10 (page 31) provide TCP window scaling factor and window
size settings for specific WAN environments.
NOTE: The TCP window size recommendations listed in Table 4 (page 28) through Table 10 (page
31) are based on low-loss 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.
