If you get the 3662 now, you probably won't need the 7200 Cisco 3660 - 120,000pps Cisco 7204VXR or 7206VXR with NPE300 - 300,000 pps Cisco seems to release a new NPE for the 7200 series ever year. They've recently released the NPE400 which can do 400,000pps, and take up to 512MB of RAM. Anyway, at minimum a 7200 is twice as fast pps wise. Also, Cisco isn't the only router vendor. Now, this isn't a Cisco list... so something about FreeBSD: I'm now sure what kind of pps rates a FreeBSD can handle. I'm thinking that fastest available hardware is a probably about 100,000 pps, but I have no data. Since FreeBSD has to put all packets through a software path, and has noaccess to helpful hardware helpers (ie. checksumming). To put that into perspective, 100BaseT ethernet with 64 byte frames is just a bit under 150,000 pps. That isn't a real possbility in most applications, but can be an issue if you are being DoSed, or run extreme applications (ie. UDP based chat server). > - Forrest W.
