The value configured here is rounded up to the next multiple of 8 KBytes internally. The TCP window size specifies how much outstanding data (data not yet acknowledged by the receiver) may be sent on one TCP connection. The window size is also the receive buffer size for each TCP connection. The recommended TCP window size is the expected bandwidth multiplied by the round-trip time (RTT). For example, the optimal window size for a 100 Mbit/sec connection with a 5 msec RTT is 100Mbit/sec * .005 sec = 0.5Mbits or about 65 KBytes. The value 0 is a special value meaning 'Auto'. In Auto mode, the switch selects the optimal receive window size for each TCP connection independently. The window size is based on the TCP stack measured round-trip times. Each connection is adjusted dynamically as the connection's RTT changes. In the case of oversubscription, buffering resources are distributed fairly across connections to the extent possible. In the auto mode, each connection has a minimum window size of 128 KB and a maximum window size of 8184 KB. The TCP window size may be manually changed at any time by setting this MIB variable. The new value begins taking effect immediately. Large changes may take a few seconds to become fully effective, as the window size changes gradually.

For example, the optimal window size for a 100 Mbit/sec connection with a 5 msec RTT is 100Mbit/sec * .005 sec = 0.5Mbits or about 65 KBytes. The value 0 is a special value meaning 'Auto'. In Auto mode, the switch selects the optimal receive window size for each TCP connection independently. The window size is based on the TCP stack measured round-trip times. Each connection is adjusted dynamically as the connection's RTT changes. In the case of oversubscription, buffering resources are distributed fairly across connections to the extent possible. In the auto mode, each connection has a minimum window size of 128 KB and a maximum window size of 8184 KB. The TCP window size may be manually changed at any time by setting this MIB variable. The new value begins taking effect immediately. Large changes may take a few seconds to become fully effective, as the window size changes gradually. TCP window size changes do not interrupt the remote gateway traffic."
