Greg has laid out a great bit of information and I would like to add just one possibility to the list of budget 10GE routers: Vyatta. According to a recent press release from that company (http://www.vyatta.com/about/pressreleases.php?id=51) they offer a product that is "2 to 3X higher performance at a cost savings of more than 75 percent" when compared to Cisco's 7200.
"Vyatta operates at Layer 3 wire speed across three Gigabit Ethernet ports in full mesh when forwarding 512-byte frames or higher."
3x1 GE << 1x10 GE
It appears that I put my foot in my mouth. I have read several claims that the Vyatta software is scalable to 10G, most notably here: http://www.networkworld.com/news/2008/031708-vyatta-open-source-router.html. Upon further investigation, I have been unable to substantiate that claim. My experience is similar to those who have posted here, pps is the limiting factor - usually somewhere between 500-800K. Apparently I was over eager to believe that more had been achieved. To Ann's question on resources; I have only used Linux routers with 1G ports but have surpassed 10G total throughput (up+ down) using various dual proc set ups, most often Intel Xeon in Dell servers. A gentlemen by the name of Martin Pels wrote a good paper on the subject early last year that can be found here: http://docs.rodecker.nl/10-GE_Routing_on_Linux.pdf. He hit a wall at 700K pps and was using two dual core Intel Xeon 64bit 2.33GHz CPUs and 2GB of RAM in a Dell PowerEdge 1950. ~Chris
