P= owerful enough to replace my KVM-qemu, vde, ... setup - nice work! My kvetch is that they are using a 100 buffers, (come on, use 1000, FEEL the bloat) ... and the second part of the experiment uses 20 buffers, and I doubt that the structure of it will show the side-effects what such a size can cause in things such as tcp admission control. Perhaps that's handled in a later module. Either way it looks like a nice class, and a quick glance over mininet makes me want to run screaming from ns2 as fast as possible in it's general direction. > > Hagen > > -- > http://protocollabs.com --=20 Dave T=E4ht Fixing bufferbloat with cerowrt: http://www.teklibre.com/cerowrt/subscribe.= html
