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 > > Regards, > Bill Herrin > > > -- > William D.
