State of sysmocom/master and upcoming work

Hi, Daniel and me spent another day in the sysmocom office to go through the PCU code. We finished clean-ups, made some simple manual tests and looked at the traces. We will work on the following items during the next weeks: * For DL handling and multi-slot allocation more than one slot will only be allocated _after_ the TBF is re-used. E.g. for a simple download this might mean a single slot is used for the entire download. Daniel made a prototype to send a packet downlink assignment directly _after_ the assignment through the CCCH has completed. We manage to run into a use after free in the TBF code but will work on it. The issue is that the start of a TBF will take a bit longer. We might want to add some heuristic to decide when or when not to do it. * Re-sending and window stalls. When the entire window has been sent once, resending will start but when the ACK/NACK is arrived the resending will conntinue. As it is more likely that frames have arrived we should stop the resending and increase the window. This will increase the throughput. cheers holger -- - Holger Freyther <hfreyther(a)sysmocom.de> http://www.sysmocom.de/ ======================================================================= * sysmocom - systems for mobile communications GmbH * Schivelbeiner Str. 5 * 10439 Berlin, Germany * Sitz / Registered office: Berlin, HRB 134158 B * Geschaeftsfuehrer / Managing Directors: Holger Freyther, Harald Welte
