2.9 Supported Network Topologies
Dual port products designed with this toolkit can be used in a wide variety of network configurations.
This single hardware design will support various network topologies. Irrespective of the network
configuration used, a dual port end device will always have a single IP address and a single MAC
address. This simplifies both configuration requirements and firmware changes required.
Figure 3 shows hierarchical star topology with commercial off the shelf (COTS) switches. Either port
of a dual port end device may be used to connect to COTS switch to realize hierarchical star network
topology.
Figure 3 Hierarchical Start Topology
Figure 4 shows a hybrid daisy chain and hierarchical star topology. Single port end devices can be
connected to a daisy chain at one of the ends of the chain, or through a standalone three port device that
provides the daisy chain capability in the middle of chain. Figure 3 also shows a COTS switch in the
middle of a daisy chain.
