The figure shows the Base Node chain comprising of the CC node connected to the EP Node that is in turn connected to the DC node. The EP node in the Base Node Chain is also connected to the custom AP node in system 1 (shown in red) and custom AP node from system 2 (shown in purple). The custom AP node from system 2 is connected to the custom DC node from system 2 (shown in purple). The custom AP node in system 1 is in turn connected to the DC nodes in the base node chain (shown in blue) as well as the DC node in the custom node (shown in red) chain.
