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.

Sure. You create an LSP with a vrf (routing-instance in Juniper-ese) to place the traffic onto it. The LSP is manually configured at each hop to traverse to the far end router and that one then points back at the input router where it is again reversed back towards the destination. Loop as often as required to saturate the link. (I was tempted to just say "rinse and repeat, but that might not be clear to those not in the U.S.) For information on ANI (and I am not sure if new proposals are being accepted), see: http://www.es.net/RandD/advanced-networking-initiative/ > On Thu, Jul 12, 2012 at 6:43 AM, Kevin Oberman wrote: >> >> On Wed, Jul 11, 2012 at 1:31 PM, Sami Halabi wrote: >> > Hi, >> > >> > We have several boxes using 10G cards and using most of the bandwidth. >> > as a future vision i would like to ask if someone ever combined hardware >> > with freebsd/linux to saturate 100Gbit of traffic. >> > what hardware (server, NICs, platform) and software do you recommend >> > that >> > would allow me to acheive my goal? >> > >> > Is it possible with servers ? or i need dedicated hardware >> > (cisco/juniper/other?) if dedicated hardware needed, i would be glad to >> > hear from your experience what do you recommend in terms of performance >> > and >> > price. >> >> 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.
