The traffic is Bernoullian with the
load of 60 percent and hot spot distribution with the factor of 0.6.
The different flows arriving from the input ports of
the LB-Clos are enqueued into the virtual central-module queues (VCQs) at the input ports, where a VCQ is sequentially
chosen for each flow. Then the packets are distributed
uniformly to the central stage because of the VCQs. At the
output ports, the packets are reordered according to their
sequence numbers. As we vary the switch size of both
switches from 4 to 529
