Your light traffic graph is puzzling, with the synchronized drops. Is it possible for you to do another test run, same setup, with codel or pie? On Thu, Nov 22, 2018 at 5:57 AM Jendaipou Palmei wrote: > > Hello Jonathan and Dave, > > Thanks for your timely inputs. > > We have implemented COBALT

[Cake] COBALT implementation in ns-3 with results under different traffic scenarios

Hello Jonathan and Dave, Thanks for your timely inputs. We have implemented COBALT in ns-3. The main C++ file is here: https://github.com/Daipu/COBALT/blob/master/src/traffic-control/model/cobalt-queue-disc.cc We have also added Queue length and Throughput graphs for COBALT in our wiki:
