WhatisMFPA?

HowDoesMFPAWorkinCDMA20001xEV-DO?
MFPAinCDMA20001xEV-DOworksbyusingaTransmissionControlProtocol/InternetProtocol(TCP/IP)stacktoallocatebandwidthtodifferentdataflows.Thestackusesdifferentalgorithmstomanagebandwidthallocation,suchasweightedfairqueuing(WFQ)andrandomearlydetection(RED).Thesealgorithmshelptoensurethatdataflowsaregiventheappropriateamountofbandwidthbasedontheirprioritylevel,ensuringthathigherprioritydataflowsreceivemorebandwidththanlowerpriorityflows.
