(i) a dimension queuing structure for a first virtual channel (VCO) within a second node of the ring network (100; 200; 300; 400; 500; 600) if the number of hops is greater than the threshold hop value; or (ii) a dimension queuing structure for a second virtual channel (VC1) or a turn queuing structure within the second node if the number of hops is equal to or less than the threshold hop value. <EOS>
