This object denotes the default value for the
number of IPDUs that must be acknowledged
before the working window size (Ww) can be
incremented by 1 when the working window is not
equal to the maximum transmit window size (TW).
It controls the gradual incrementing of Ww in
congestion situations.
This function is not described in the IEEE
802.2 specification [5]. However, it is listed
in the IBM Token-Ring Network Architecture
Reference [6] as the Nw parameter and is widely
implemented.
This port default value may be overridden by a
non-zero SAP default value in the llcSapAdminNw
object.
