[c-nsp] IP SLA Scalability

[Ben Steele]

Hi,

Has anyone ran a rather large amount of SLA probes from a router who can
comment on the cpu performance characteristics on how it scaled for your
particular platform?

Specifically looking to see if its feasible to expect a router to be able to
go upwards of 500+ simultaneous monitors(looking at a total of about 10-15k
pps of udp-jitter probes in total).

Also any thoughts on the best platform for the task? the 7201/ASR1002-F seem
like a possible good fit and would like to aim for something in its category
- price on the lowerish side of the scale, rack space used minimal, large
cpu, mpls-te capable, can accept SFP optics. Ultimately the cheapest box for
the task is what i'm after, those devices may be an overkill and if I can
get away with a 3800 ISR or less then even better.

Before anyone says that I should look at another vendor/solution, this is
already being done in the background. I am purely after what a Cisco router
can offer in this regards, i've never come across more than about 20 sla
probes on a router before so am interested to hear the results.

Cheers,

Ben
