[c-nsp] Router recommendation

Tue Sep 19 18:05:03 EDT 2006

Let's step back from this and look at it the larger picture and your
needs:

How many customers (ie, how many pppoe/lt2p sessions)?
How many packets/second?
How many megabits/second?

We started running out of steam at around 1000 users on an NPE-300.
Our users were some filesharin' fools though.  Quebecers outstripped
Ontarians in their per capita b/w usage by like 50%.

We found that the NPE-G1s were about 3.5x the performance, so we
upgraded.  With about 1700 users online, 75 megs down, 50 megs up,
27kpps, cpu utilization peaks at right around 40%.

Aggregation routers just carry our OSPF, not full internet routes, and
run just fine (69 megs free) with 256 megs in 'em, no reason to put in
a gig.
