Performance based/Intelligent Routing

Hi all,

I've built a great many large scale ISP and Data Center networks in the past.

As you know many many years ago  BGP metrics became inefficient in making good routing decisions. So in  the early 2000's companies began to come out with Intelligent Routing  appliances that would "learn" traffic destinations and calculate  latency/loss/jitter to and from destinations, then use that calculation  to determine best path. Then best path would be injected into route  table. I have been out of touch for the last few years. I assume that  calculating traffic decisions has become even more complex, even down to  the application layer. That is how I learned about Cisco NBAR2 and  Cisco Adaptive Intelligent Routing AIR. Anyway, what does Cisco provide  today to help ISP and Data Center routers do performance based  routing/intelligent routing?

Thanks

Justin Franks

I like networks that do what they're supposed to do. Huge Cisco fan. Multi-vendor networks? Like, why?

Either one will do fine.  If you put your thread in the wrong section, one of the Cisco guys will recommend you the right place to move it.

Unfortunately, making multiple posts doesn't guarantee that you'll be able to monitor both.

I found it.

Cisco came out with OER which I didn't use much but should have.

Then in 2008 Cisco came out with PfR.

PfR replaces OER.

Guess I have some catchup to do.... I'm a LITTLE out of touch, lol.
