  We propose a configuration scheme for a load-balancing Clos-network packet
switch that has split central modules and buffers in between the split modules.
Our split-central-buffered Load-Balancing Clos-network (LBC) switch is cell
based. The switch has four stages, namely input, central-input, central-output,
and output stages. The proposed configuration scheme uses a pre-determined and
periodic interconnection pattern in the input and split central modules to
load-balance and route traffic. The LBC switch has low configuration
complexity. The operation of the switch includes a mechanism applied at input
and split-central modules to forward cells in sequence. The switch achieves
100\% throughput under uniform and nonuniform admissible traffic with
independent and identical distributions (i.i.d.). These high switching
performance and low complexity are achieved while performing in-sequence
forwarding and without resorting to memory speedup or central-stage expansion.
Our discussion includes throughput analysis, where we describe the operations
that the configuration mechanism performs on the traffic traversing the switch,
and proof of in-sequence forwarding. A simulation study is presented as a
practical demonstration of the switch performance on uniform and nonuniform
i.i.d. traffic.
