$NCP Modifiers
FRAMESIZE n
Default: 132
Units: Words
Range: 64 through 250
The $NCP FRAMESIZE modifier specifies the maximum packet size that $NCP can
send in the network. This value must be less than or equal to the Expand line-handler
process’s FRAMESIZE modifier but, it cannot be greater than 250. It is not required
that this modifier be the same for each $NCP in the network.
MAXCONNECTS n
Default: 5
Units: Not applicable
Range: 1 through 255
This modifier specifies the number of CONN requests that can be outstanding on each
path from the system.
MAXTIMEOUTS n
Default: 3
Units: Not applicable
Range: 1 through 255
This modifier specifies the maximum number of times $NCP will attempt a CONN
request.
NETWORKDIAMETER n
Default: 15
Units: Not applicable
Range: 1 through 254
This modifier specifies the maximum number of hops (intervening nodes) in a path
between two nodes. You should set n to the longest path between any two nodes in
the network plus one. You should use the NETWORKDIAMETER modifier with the SH
routing algorithm. The NETWORKDIAMETER modifier is explained in detail in Split
Horizon (SH) on page 18-30.
