Hi Noam, The minimum speed of 8k is set in lfd_shaper.c: > 50: max_speed = host->spd_out / 8 * 1024;
It's primitive, but that's the number. It could be (hacked out to a #define and then) tuned to a lower number, if you wanted, but it would be a compilation you'd have to build and support on your own. (Oh, for this to be in a pluggable module) Of course, what's immediately after that? > /* Compensation for delays, nanosleep and so on */ > max_speed += 400; The arbitrary padding, to account for delays in transit, would be larger than your custom tuning. You should expect, even in a best case, some kind of jitter in that regard, even if you ripped that out completely. You may also want to redo the timing in lfd_shaper so that it's more granular than per-second. Sorry you got invited to the wrong list: the question looked a lot like a config question until about the 5th or 6th re-write of my note here. It's most definitely a coding question, and your message was definitely targeted at the right list. - bish > Hello, > > I saw in the documentation that currently the lowest configurable > speed for vtun is 8 Kb/s. > Is there a good reason for that? > I want to simulate a very low bandwidth medium - 128 bits per second. > Is it possible for me to tweak vtun to do that? > Would it work? > > Thanks, > > Noam. ------------------------------------------------------------------------- Sponsored by: SourceForge.net Community Choice Awards: VOTE NOW!
