I am grateful for any pointers towards IP channel simulation and/or PEPs such as SCPS TP in OpenBSD.
You could try tunbridge, which does loss, delay but not (I think) jitter. "tunbridge(1) emulate a long, possibly lossy, link using the tun device. tunbridge(1) reads packets from the tun(4) device, creates a delay, packet loss, and packet shaping, and then, reinjects the packets to the same tun device." http://www.iijlab.net/~kjc/software/dist/tunbridge-0.1.tar.gz -- Darren Tucker (dtucker at zip.com.au) GPG key 8FF4FA69 / D9A3 86E9 7EEE AF4B B2D4 37C9 C982 80C7 8FF4 FA69 Good judgement comes with experience. Unfortunately, the experience usually comes from bad judgement.
