Hi, I think I did not understand all the acronyms I was looking at when I wrote my e-mail. :) My basic goal is that I would like to experiment with SONET on a PC computer (on a small scale, for learning purposes only) without having to use ATM equipment (if I can avoid it). I am interested in whatever existing SONET software simulators for FreeBSD or FreeBSD device drivers are out there which could help me do this. I suggested PPP/IP over SONET, but based on some further reading, it looks like I would need special hardware to do this. For example, PMC-Sierra has a special chipset which does packet over SONET (POS): http://www.pmc-sierra.com/pressRoom/pr/1998092100.html http://www.pmc-sierra.com/products/details/pm5351/index.html This chipset is implemented in equipment from various router vendors, such as Cisco: http://www.cisco.com/warp/public/cc/pd/rt/12000/prodlit/gspos_an.htm I couldn't find any information about NIC cards with POS capabilities which could plug directly into a PC. As you mentioned, there is some interest in encapsulating Ethernet inside a SONET transport. There is a tutorial of Ethernet over SONET here: http://www.commsdesign.com/design_corner/OEG20020418S0005 (Part 1) http://www.commsdesign.com/design_corner/OEG20020425S0003 (Part 2) So there is a lot of stuff going on, but is any work going on in this area which would work under FreeBSD? ;) I just want to use a FreeBSD PC to learn about SONET, without getting lots of expensive equipment. If there is a software simulator of SONET that works on FreeBSD, I would be interested in that.
