_rexmit_interval_min Parameter

Description

Specifies the default minimum retransmission time out (RTO) value. The calculated RTO for all TCP connections cannot be lower than this value. See also _rexmit_interval_max Parameter.

Default

200 milliseconds

Range

1 millisecond to 7,200,000 milliseconds

Dynamic?

Yes

When to Change

Do not change the value in a normal network environment.

TCP's RTO calculation should cope with most RTT fluctuations. If, in some very special circumstances, the round-trip time (RTT) for a connection is about 10 seconds, increase this value. If you change this value, you should change the _rexmit_interval_max parameter. Change the value of _rexmit_interval_max to at least eight times the value of _rexmit_interval_min. The TCP_RTO_MIN socket option can be used to change the initial retransmission timeout on a per-socket basis.
