DURABLE: { 0:all }
The TCP window size used for all TCP data connections in this
iFCP remote connection, in KBytes. 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. TCP window size changes do not
interrupt the remote gateway traffic.
