This class implements a simple downlink scheduler for rtPS flows.
Doxygen introspection did not find any typical Config paths.
The DL-rtPS-Scheduler assigns the available bandwidth the service flows in the following order: IR Connections, Broadcast Connections, Basic and Primary Connections, UGS Connections, rtPS Connections, nrtPS Connections, BE Connections. The IR, Broadcast and Basic/Primary Connections must transmit all packet in the queue. The UGS flows can transmit the quota of date equal to the "Grant Size" (that is one of service flows QoS parameters) according to their requested MaxLatency (another QoS parameter). All rtPS flows are able to transmit all packet in the queue according to the available bandwidth. The bandwidth saturation control has been implemented to redistribute the effective available bandwidth to all rtPS flows that have at least one packet to transmit. The remaining bandwidth is allocated to rntPS and BE Connections.
No Attributes are defined for this type.
No TraceSources are defined for this type.

Downlink Scheduler for rtPS connections.
availableSymbols | available symbols for rtPS flows |
This method represent the DL Scheduler for rtPS connections. The scheduler is designed to serve all rtPS connections that have at least one packet to transmit, every DL Subframe. To each rtPS connections are allocated, at the beginning, the bandwidth to transmit a quota of data equal to the queue length. If the sum of all pre-allocated bandwidth exceed the available symbols for rtPS connections, the Channel Saturation Control function is called to redistribute the available bandwidth.
