INB Interface
The INB Backplane is designed to transport fixed length data blocks between
modules in the SmartSwitch 9000 using a Time Division Multiplexing (TDM)
design. The SmartSwitch 9000 INB bus delivers 2.0 Gbps of true data bandwidth
with all control and management communication being serviced on the 8 bit out-
of-band bus. The INB can time slice its bandwidth using one of three methods.
The default method is standard TDM round-robin bandwidth arbitration, the
second method is for modules to reserve a specific amount of bandwidth using
INB Manager, Cabletron’s INB Bandwidth Arbitrator, the third method permits
the lowest slot number to use any bandwidth not used by the previous two
methods.
