Re: cisco routers that can handle 100 meg internet connection I have 2811s in production with NAT and some simple QoS rules setup and a couple of vlans. Using iperf I can push 100Mbps through the router to one of the Vlans using multiple streams.
If we start doing lots of NAT rules and a large number of clients with phones and lots of PPS I often use a 7200 with an NPE400.

kudos:7 | When we first had our DS3 installed, I converted the PIX (520) configuration to IOS for the the 2851. The configuration is simply not that complicated, and with 10 people in the office (no bittorrent!) the number of dynamic NAT translations is really low. I could not get the thing pass more than 28Mbps. NAT was simply KILLING IT. Putting it back like the integrator had it -- pure routing -- and I could flood the DS3 all day long... PIX load: 6%. (and that's with all of the internal office traffic flowing through it too.)
That router is currently sitting in the hallway, and nobody's told me I cannot take it over again. I think it's time put that thing in front of the Spirent!
(Without services, an 1811 can do line rate 100M -- ~20% CPU as I recall. I'll have to fetch my idle 1811 and test it as well.) |

I think the obvious point is being missed here.
How many packets per second do you want to do?
Bandwidth is a meaningless number for hardware selection criteria as it is not the length of the packet that consumes the CPU time, but the header of the packet. |
