How SBM Works
Downlink traffic is fully under HBS control, so that it can allocate any unused downlink time
slots to a very busy link, whether allocated or in free pool. The busy link may operate at an
extremely high throughput, 1000% utilization not being uncommon as will be seen in an
example below.
Uplink traffic is completely unpredictable. Again, in the case of a very busy link with other
links relatively idle, the HBS will allocate extra uplink time slots to the busy link from free pool
only. If all of the uplink time slots are allocated, then SBM will not operate in the uplink
direction.
The RADWIN Manager provides facilities to configure separate uplink and downlink time slots
as shown in Figure 10‐1 and Figure
tabular and graphic utilization statistics demonstrated below.
