Hopefully I can stay within the bounds of NANOG's traditions against marketing material if I limit myself to thanking Kyle for his comments, and encourage anyone attending NANOG 27 who would like more info on automated control of routing for load objectives to come find me at the meeting.

Take a look at a product called "Path Control" by RouteScience.
I have seen their product in action and it is very slick. 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.

Dear NANOGers,
I have a very hands-on question: Suppose I am a network operator for a decent-sized ISP, and I decide that I want to "divide" aggregate traffic flowing through a router toward some destination, in order to then send some of it through one route and the remainder through another route. 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,
