+| | ... | - tg_if2 - TG interface towards DUT2.
+| | ... | - dut1 - DUT1 node
+| | ... | - dut1_if1 - DUT1 interface towards TG.
+| | ... | - dut1_if2 - DUT1 interface towards DUT2.
+| | ... | - dut2 - DUT2 node
+| | ... | - dut2_if1 - DUT2 interface towards TG.
+| | ... | - dut2_if2 - DUT2 interface towards DUT1.
