Snake topology does conserve IXIA/Spirent ports but will not allow you
to test everything. I see no practical way of just having bunch of
IXIA/Spirent ports to verify behaviour under various types of
congestion. Unfortunately the 'bunch' is getting rather large, since
even the smallest atom of a modern networking chip may contain dozens
of 100GE ports.
