I just finished a netmap-enabled version of ipfw/dummynet, which runs in userspace and is able to process over 6 million packets per second (Mpps) with simple rulesets, and over 2.2 Mpps through dummynet pipes (tested on an i7-3400 connected to VALE ports; VALE is a software switch part of netmap). You can find it at http://info.iet.unipi.it/~luigi/dummynet/#8696 It works on FreeBSD and Linux. It even run on OSX, but there is no netmap support there; any interest, Apple ? In any case, it should be simple to adapt the network backend to talk to other devices. To run this you might want to use the most recent version of netmap, also recently updated so it works with recent kernels http://info.iet.unipi.it/~luigi/netmap/ (the code is already in FreeBSD HEAD). On passing, I have also updated the dummynet distributions for Linux and Windows, which should now compile for most recent version of Linux, and for Windows 32 and 64 bit: http://info.iet.unipi.it/~luigi/dummynet/ cheers luigi
