No use of static oversubscription common in satellite networks and instead is based on average peak time information rate data utilization.
Virtual Paths are Point to Point
One logical path connects one terrestrially served location with one satellite-served location. Multiple logical paths may be carried over a common physical medium or carrier.
Each Path is Independent of All Other Paths
Each logical path has it’s own Quality, Class, and Committed Information Rate. Each path's payload can be unique from all other paths in the same carrier.
Logical Isolation
Logical paths are formed within the bandwidth of a trunk independent of the space segment. Each path uses and/or reserves space out of the available trunk bandwidth. The trunk’s bandwidth is determined by the size of the space segment.
Committed Bit Rate
With CBR class of service a logical path receives a set amount of data bandwidth regardless of it’s utilization. If current traffic demands exceed the set amount of bandwidth the path may burst. CBR is the same as Static CIR. It is also the logical equivalent of a dedicated space segment. Unlike a dedicated space segment, a CBR path can cost effectively be provisioned with as little as 64 Kbps with a space segment utilization of 44.25 kHz.
Variable Bit Rate
With VBR class of service a logical path receives a variable amount of bandwidth based on current utilization. The availability of bandwidth is guaranteed up to a set rate. VBR is the same as Variable CIR. VBR allows bandwidth to be overbooked while insuring to a larger degree performance expectations.
Unspecified Bit Rate
With UBR class of service a logical path receives any available bandwidth up to it’s maximum provisioned rate. UBR bandwidth is usually heavily over booked. UBR paths are submissive to VBR paths.
Burst Space
The burst space is used in normal operation to provide room for the bursting of CBR and VBR path when usage exceeds their protected bandwidth. During peak traffic hours the Bust Space provides an emergency space for VBR paths to form if space is not available. This prevents congestion when more then the calculated number of simultaneous VBR paths in utilization are exceeded.
