Julian, Can you take a look at the code http://www.riss-telecom.ru/~vitaly/ Its already based on netgraph, and it can do [almost] everything that ALTQ does. The only thing it lacks compared to altq is a large selection of queuing disciplines. It is also much faster than altq. bwman also has support for lower and upper bound of bandwidth, unlike ALTQ. -alex On Tue, 21 Nov 2000, Julian Elischer wrote: > I'd like to put to the networking list that we take a serious look > at making the ALTQ code from Kenjiro Cho a standard part of FreeBSD. > > I'm looking at adding some queueing methods into Netgraph > as part of some work being discussed by > phk, Archie, Brian and myself, Looking into this I note that > for the to be really effective we really want to have an > overall queueing strategy for the OS.
