Scenario 1; Figure 2-20 Throughput Scenario 1 - ND SatCom SKYWAN IDU 7000 Manual

Scenario 1

Both IDU1 and IDU2 are configured for stream mode Normal. The traffic mix (see figure 2-20)
consists of:
- A non real-time IP based PC application with a bidirectional bandwidth requirement of 128
kbps between these two stations.
- Additionally 6 parallel voice calls served by SkyWAN
tive between the stations.

Effect
Due to the defined guarantee for both stations, the 6 dynamic slots needed for the PC applica-
tion will always be available, irrespective of the general congestion state of the network. For
the voice calls each station would need 3 streaming slots.
As long as there are enough free slots available in the common streaming pool, these calls can
be set up. However, there is no guarantee for the calls: if other stations have already used a
part of the streaming pool, some of the voice calls may be blocked.
