To achieve the efficiencies of pooling (that is, to realize the
effects of the law of large numbers) while, at the same, providing
the quality of service committed for each satellite router, the HX
System uses a number of techniques. One important element is
the concept of inroute quality of service (IQoS) plans. An IQoS
plan is simply the logical partition of inroute bandwidth together
with the satellite routers that can access the logical bandwidth.
The assigned logical inroute bandwidth is designated as Open and
is typically used by satellite routers configured for dynamic
stream (otherwise known as best effort access).
Figure 6
illustrates the structuring of the inroute bandwidth.
