Master-To-Master (M2M)
FIG. 4 shows that a maximum of 64 systems can be interconnected using a two-dimensional
interconnection topology. Using a three-dimensional topology, even more systems can be interconnected
(FIG. 5).
FIG. 5 Three-dimensional view of the maximum number of interconnected NetLinx masters
FIG. 5 shows that a maximum of 512 systems can be interconnected using a three-dimensional
interconnection topology. Note that for the diagram in FIG. 4 that a single NetLinx master may have up
to eight connections to remote masters (all 6 sides of the "box" plus two diagonal connections).
The maximum number of TCP/IP connections supported by a single master is 200 simultaneous TCP/IP
connections.
Another possible connection topology is to establish communication hubs that optimize the traffic with
adjacent masters but still allows connections to other masters, as shown in FIG. 6.
FIG. 6 Clustered master topology
When determining the interconnection topology of many NetLinx Masters, special consideration should
be made to the Masters that communicate large amounts of information with each other. Thus, if you
have 2 systems that share devices, control, or information, they should be side-by-side in the topology,
not at opposite ends of the connection Matrix where each message is forced to pass through several
NetLinx Masters.
