We are a RouteScience customer. We are using this box and it rules. We have been extremely happy with the results. We have multiple OC-x circuits that we are engineering traffic over, and this box gives us the ability to "see" things that we could not see before. It also really allows us to differentiate our upstream providers - or tell that they are really all the same. The reports it produces are excellent. We have even used it to negotiate better SLAs and pricing with our bandwidth providers. Feel free to email me off-list if you want more information. Sincerely, Todd A.

Does exactly what you want, plus a whole lot more and does it transparently (so if it fails you aren't SOL) via manipulating BGP tables and nexthop based on a multitude of criteria.

Thus, I desire to enforce some traffic engineering decision. How would I be able to accomplish this "division"? What technologies (even if vendor-specific) would I use? I can think of some methods like prefix-matching classification and ECMP, but I am still not sure exactly how the latter works in practice (at the router level) and how one may set them up to achieve such load-sharing. Thank you for your expertise and lore, -- Stanislav Rost <stanrost () lcs mit edu> Laboratory for Computer Science, MIT
