Hello, I'm new to linux development and am working on creating a qdisc module, similar to those under net/sched/sch_*.c. Currently I'm stuck on two things.
1. What's the best way to set the maximum bit rate? 2. How do I determine the RTT for packets? For (1) I'm currently tracking the number of bits sent, and only sending packets if they stay within the appropriate rate bound. Is there a better way to do this? I've looked at net/sched/sch_netem.c, and as far as I can tell it determines the delay between packets for a given rate and sends them after that delay has passed. However, when I tried to do this I got inconsistent rates, so I think I may be missing something. As for (2) I'm not sure where to start. Thanks in advance for any advise.
