Detailed Description

This class implements a simple uplink scheduler for rtPS flows.

The UL-rtPS-Scheduler work in this way: At the beginning of the UL sub-frame some symbols are allocated to the rangingInterval Messages, DSA Messages, UGS grants and UGS/rtPS/nrtPS/BE poll. Then, the remaining available symbols are allocated to the all rtPS flows according to their requestedBandwidth. The bandwidth saturation control has been implemented to redistribute the resource if the sum of requestedBandwidth exceed the available bandwidth. At the end, if there are some free symbols, their are allocated to nrtPS and BE Connections.

Reimplemented from ns3::UplinkScheduler.

void ns3::UplinkSchedulerRtps::ULSchedulerRTPSConnection	(	uint32_t &	symbolsToAllocation,
		uint32_t &	availableSymbols
	)

Uplink Scheduler for rtPS connections.

Parameters:

	symbolsToAllocation	symbols to allocation for UpLink Subframe
	availableSymbols	available symbols for rtPS flows

This method represent the UL Scheduler for rtPS connections. The scheduler is designed to serve all rtPS connections that have at least one packet to transmit, every UL Subframe. The methos selects all rtPS connection that have al least one packet to transmit. To each rtPS connections are allocated, at the beginning, the bandwidth to transmit a quota of data equal to (RequestedBandwidth - GrantedBandwidth). 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.
