The PNet based on 3 cascaded 8-port switches shown in my talk needes only a 9 bit path address.


This isn't correct. Since 4 8-port switches have to be traversed, see the attached figure, one needs 4*3 = 12 bits.

At this place another correction: In my talk I mistakenly wrote that the PEX 8532 is a AS switch. It is a PCIe switch, a true AS switch is announced.
