Just sayin'.... 10gig nics are becoming ubiquitous in datacenters. 10Gigabit on mainboard is pretty ubiquitous in in bladeservers and adds about $150 to the BOM of a 1u pizza box in volume (for copper). > "Lash enough software routers together that run at 40 gigabytes per > second, and you get what is essentially a single-terabit router. > Using such a system, routers might some day run completely in > software." > > Ahh.. but the lashing is the tricky part that costs the big bucks, as > these guys will undoubtedly discover - life will get a lot more > complicated once they saturate the first PCI backplane and need a > second.

In any event, they don't have to, we have quick-path which 100Gb/s per-direction per path at 3.2ghz or pci-e 3.0 which is 8Gb/s per lane and comes with all the lovely logic you expect from a (non-ethernet) switch fabric. What it really comes down to is packets per watt or packets per dollar, if it's cheaper to do it this way then people will, if not BFD. >
