I don't know of any 100GE hardware for any PC, but I may be a bit behind on the times. The way we saturate a 100GE with a FreeBSD (or Linux) system is using a 10G transmission stream and loop the data stream over the net using MPLS. Works quite well, though no end system ever sees more than about 9.9G, the routers do. We are using Alcatel-Lucent routers at this time for our national test network. It is available for research by educational, commercial and research organizations for a little longer as a federally funded testbed for 100G research. When the funding for that project runs out, most of the hardware will be re-purposed and will no longer be available for research. gnn@ mentioned it about a year ago and suggested that some FreeBSD people might want to submit proposals, but I sw no responses. We have tested with Juniper and they will work, too. All 100G hardware is just a mite pricey, though it has dropped tremendously over the past year and a half and I expect it will continue to do so. -- R.
