I have two simple dummynet rules in place (with ipfw):
- one pipe limits inbound
- one pipe limits outbound
However, if there are multiple connections taking
place, all over fast links, the pipe gets saturated.
This is not so bad, but I am not convinced it is
allocating bandwidth fairly between all participants
during saturation.
Two questions:
- is there a simple setting that says "allocate
bandwidth evenly between all connections in a
saturated pipe" ?
- alternatively, is there a minimum speed per
connection that I can establish for a dummynet pipe ?
Presumably actual performance would drop below the
minimum if the product of connections * minimum was
less than the total bandwidth of the pipe, but as long
as that wasn't true, everyone would at least get
reasonable speed, instead of one client eating the
pipe and everyone else trickling along...
Thanks.
