2016-08-03Fix issue with DL window size calculationAravind Sirsikar1-0/+18
During performance testing it is found that when DL data alone is triggered using Iperf, window size was being calculated as 160 for EGPRS DL even when window size 480 is configured from VTY of osmo-pcu.cfg. There was an issue with gprs_rlcmac_tbf::update function causing this erroneous behavior.
2016-08-03Add support of 4 TS allocation for Multi UE DLAravind Sirsikar1-2/+2
During Performance testing of Multi MS, It was found that during DL data 1st MS gets 4 TS allocation for DL and next MS gets 3 TS allocation even when NITB is configured with 4 TS for DL. causing issue with data rate distribution between MSs. This patch will ensure the proper DL data rate destribution between the MSs.
