Well, there are hundreds of thousands of completely ad-hoc solutions of varying degrees of effacy. Getting it down to mere hundreds would be be a good start. > Really, there is no "one big thing that solves all problems, > automatically".

Well, funding this work would be a great thing for everybody, and we're working on it, and boy do we appreciate the volunteerism as it stands. Everybody, including me, is basically working for free here, (I'm leveraging the lab at gatech and am (now) making a little money supporting their bismark effort, but just a little) - but fixing the internet as a whole is a worthy goal, don't you think? It beats building web sites.... :) > > BTW, latest stuff uses DRR & HFSC ;) > > Patrick sample script is here : > http://people.netfilter.org/kaber/shaping AWESOME! I was going to get DRR working in my next build and series of test runs. And look harder at HSFC than I have as yet. I'm told the latest iproute2 code will be out soon, once all those pieces are in place, I can beat them all up, pretty good, in the lab. > > > --=20 Dave T=E4ht SKYPE: davetaht US Tel: 1-239-829-5608 http://the-edge.blogspot.com
