Transmission Control Protocol (TCP) Configuration
Initial
retransmission
interval
(secs) This field sets the initial amount of time that TCP will
wait for a reply from a remote node before attempting
to retransmit a packet. This value is used for
connection setup when the retransmission interval has
not yet been calculated. It should be greater than the
retransmission interval lower bound.
Default value: 5
Range: 2–999
Maximum
retransmissions
per packet This is the maximum number of times that TCP will
retransmit a packet before aborting the connection.
Increase the value if connections are being dropped
prematurely. Decrease the value if there is too much
traffic due to packet retransmission.
Default value: 4
Range: 1–100
Connection
assurance
interval
(secs) This timer allows you to adjust the time you wait for
resources to be released after an idle disconnect. If the
remote connection is abruptly interrupted, TCP waits
for the amount of time calculated by the following
algorithm:
CAinterval + (CAinterval * MAXCARTX)
where CAinterval is the connection assurance
interval and MAXCARTX is the maximum connection
assurance retransmissions.
TCP drops the connection thus freeing all resources
held by that connection. Increase this value if you are
experiencing too much overhead for retries due to idle
disconnects. Decrease this value if you are waiting too
long for resources to be freed due to idle disconnects.
Default value: 600
Range: 10–32767
