The answers which you seek would be considered secret sauce to these vendors.

But you can start at running MTRs through a VRF per carrier only containing a default route, and looking at the results.

Hi,
I'm doing a research on BGP route optimisation and the performance metrics used by commercial route optimizer appliances to select better path to a prefix.

I would appreciate any information about the performance metrics used in commercial BGP route optimizers, white papers or any other document that describes how these metrics are measured and collected by commercial route optimizers. 

Thanks
