- FreeBSD + dummynet
- Linux 2.4
- Linux + NistNet http://snad.ncsl.nist.gov/itg/nistnet/
- Linux 2.2 CBQ : It's new in 2.2 and does all that shaper does and much more. The only problem with CBQ is documentation, or rather, the lack thereof. But it isn't that hard... Linux's CBQ can do more then routers and more then a lot of traffic shapping devices. It will handle the kinds of loads you are talking about with ease (I use 21264 systems to do fair queue and priorit on multiple 100Mb's streams)..
