remote speedtesting for routers?

Why can't I ask my router to run a test of the maximum speed to a location and then return the answer to me?  (Security protected of course)

A remote speed test if you will?

Possibly the answer is routers, by design, route packets and they don't usually provide a maximum speed test, although some Cisco routers used to have a hidden command for TTCP and many today support various SLA tests.

I also found you can configure the echo service, although more often than not, having a router echo packets sent to is seems to crush the CPU of the router before it crushes the link.  (NB: router software has been optimized to forward transit packets, services supported by the router are often not as well implemented for optimal performance.)

Thank you Joseph; where

Thank you Joseph; where routers are hardware based i'd agree that they only really have one function. But with more powerful devices and extra memory I was hoping that a local iPerf utility might be loadable within the unit. Its often a confidence thing, knowing that a particular segment can achieve the Mb/s expected and if you not able to do this remotely then its expensive to prove.

I'd seen the TTCP notes but as its not supported its not necessarily a common trusted platform. The  SLA tests seems much better.

Is there a particular Cisco IP SLA function you think I could use?

 

Many thanks

Also the SLA licence required

Also the SLA licence required seems like an unnecessary cost to prove something perhaps just once.

For crushing a link, to verify bandwidth, typically SLA wouldn't be to useful, as it's more about insure performance service levels are being met.

I think you're correct, a simple traffic generator shouldn't be too difficult to include in an IOS.  Cisco just hasn't seen it as useful feature, or they might be worried about the impact such a feature might cause.
