RSIZE n
(NAM), or how many times the Expand-over-IP or Expand-over-ATM line-handler
process will retry the probe of the remote Expand-over-IP or Expand-over-ATM line-
handler process before declaring the network unavailable. A value of 0 indicates that
timeouts are ignored and the connect state is maintained. See also TIMERPROBE n
and TIMERRECONNECT n.
RSIZE n
Default: None
Units: Not applicable
Range: 0 through 186
This required modifier specifies the time factor of the line for the Expand routing
algorithm. RSIZE must always be set to 1 for $NCP and set to 0 for the path device of
a multi-line path.
Starting with G06.20, you can use the new parameters, LINETF n and PATHTF n, to
set values for lines that will override all other parameters in calculating time factors.
Either RSIZE, SPEED, SPEEDK, LINETF, or PATHTF must be set or the line handler
will display a configuration error. If LINETF, PATHTF, SPEED, or SPEEDK are set, any
RSIZE value is ignored.
To change the line time factor with the ALTER LINE command, use the LINETF
modifier. For more information on establishing time factors, see Setting Time Factors
on page 17-23.
RXWINDOW n
Default: 7
Units: Packets
Range: 2 through 15 for all line types
This modifier is applicable to all Expand line types.
For Expand-over-NAM and Expand-over-ServerNet line-handler processes, this
modifier specifies the number of p
ackets that the network access method (NAM)
process can send to the Expand line-handler process before requiring
acknowledgment.
For Expand-over-IP and Expand-over-ATM line-hand
ler processes, this modifier is
meaningless but is kept for commonality between the line types. For example, because
an Expand-over-IP line-handler processes uses QIO to communicate with its
associated NonStop TCP/IP process, the Expand-over-IP line-handler process must
read all the messages on its receive queue at one time; it cannot limit the number of
messages read to the RXWINDOW modifier value because of QIO limitations.
