If we compare the scheduling process of the TSBCS/BS
and the CICQ switch, we find that the TSBCS/BS switch
can be mapped to a CICQ switch from the module level by
considering the VOMQk;l in TSBCS as the VOQi;j in the
CICQ switch. Thus, each IMk can be considered as an ILCi
in CICQ, and each OMl can be viewed as an ELCj in CICQ.
All the CMs resemble a buffered crossbar with CQ;k;l acting
as CPBi;j because all the CMs have the same queue status.
As a result, all the well-studied scheduling algorithms for
CICQ switches can be used directly in TSBCS/BS; however,
the complexity of the scheduler is drastically reduced from
OðNÞ to Oð ffiffiffiffi
N
p Þ. The matching configuration of TSBCS/BS
in Fig. 3 can be reflected by Fig. 8 in a CICQ switch.
