Item
Set whether to enable the at_most_once function. This function
means that when A receives a command, it execute it only once. In
AtMostOnc this way, such case can be avoided that A re-sends the packets to
eFlagVal B when the response from B is being transmitted in the network,
that is, a command is re-executed. The values can be 0 (false) or 1
(true), and the default value is 1.
The duration set at the timer for the at_most_once function. B
calculates the time from the point when it sends the response
AtMostOnc
message. If it receives the sent again packets within the duration
eTimerVal
set for this parameter, it will discard them. The value cannot be
larger than 60 seconds and the default value is 30 seconds.
Maximum retransmission time. After a command is sent, if no
MaxRetran response is received, this command will be sent again. If no
Timerval response is received during the time set by MaxRetranTimer, this
command will not be sent again. Default value is 30 seconds.
Set whether to configure the retransmission algorithm initial seed
RetranTime
value. The two choices are "TRUE" and "FALSE". If it is set to
rSeedFlag
"TRUE", it indicates that the first retransmission duration is set to
Val
RetranTimerSeed; or else, it is fixed to 2 seconds.
The initial seed value of the retransmission algorithm. It cannot be
RetranTime
larger than 30 seconds, and must work in coordination with the
rSeedVal
RetranTimerSeedFlag.
The retransmission suspicion threshold. It must be smaller than
RetranSus
RetranDisconnectThreshold. If the times for re-sending a command
picionThres
exceeds this value, the system enters the suspicion status and
holdval
checks the DNS address or tries other destination addresses.
The retransmission disconnect threshold. It must be larger than the
RetranDisc
RetranSuspicionThresholdval. When a system enters the suspicion
onnectThre
status, if the times for re-sending a command exceeds this value,
sholdVal
the command will not be sent again.
