Figure 5 illustrates a three
stage
TSE fabric (
depth
= 3), with a
height
of 32. Each of 512 full-
duplex STS-48 loads on 512 TBS devices are connected by four LVDS links each to a TSE. The
receive ports for each TSE in Column 0 is connected to the 4 transmit LVDS links of 16 TBS
devices, for example TSE(0,0) receives from TBS(0) through TBS(15). The transmit LVDS links
of each TSE in column 0 fan out to all 32 TSEs in column 1, with 2 links per transmit/receive
device pair. Transmit links for column 1 TSEs fan out similarly to column 2 TSEs. Transmit links
of column 2 TSEs connect back to the TBS devices. Each column 2 TSE connects with 16 TBS
devices, with 4 transmit LVDS links per device pair, for example TSE(0,2) transmits to TBS(0)
through TBS(15).The aggregate switch bandwidth is 1,280 Gb/s using 96 TSE devices and 512
TBS devices.
