I'm not really qualified to evaluate the technology, but the 4 minute flash demo on the site states that the system uses non-BGP approach to determine response time and load on selected links, as an alternative to just selecting least-hop AS statistics with BGP. Check out the 'technology' section of the Web site.

Is anyone out there familiar with a company called "routescience"? I caught
the below press release at and wanted to find out if anyone can relay any
real-world experiences with their system? It almost sounds like they are
using something like a Keynote Systems performance monitoring tool to inject
BGP path preference information.

ROUTESCIENCE DEVELOPS PLATFORM TO CONTROL BGP INTERNET ROUTING
RouteScience, a start-up based in San Mateo, California, unveiled
plans for a unique "route controller" platform for optimizing a
company's multiple ISP links by providing real-time performance
measurements of paths across the Internet to end users. Using
these performance metrics and customer preferences for ISP link
cost, RouteScience's PathControl platform determines the best ISP
path for end-users and can then automatically update the
organization's edge routers with the best path routing
information. The route performance measurement relies on a
patent-pending closed-feedback loop system that does not use
pings. Route updates are provided to the edge routers using
standard Border Gateway Protocol. A large company with multiple
ISPs would use the systems to route traffic to the ISP links that
actually deliver the best end-to-end performance. The solution
could also be used by a Tier-2/3 service provider to route
traffic to multiple backbone carriers depending on cost and real-
time performance metrics. The company said default BGP chooses a
sub-optimal route 50% - 80% of the time, depending on the number
of alternative ISP paths. Of those routes that can be improved,
an alternate ISP is on average 2 times faster. RouteScience
claims its system provides deep visibility into ISP performance
and could fundamentally change network service agreements and
pricing by moving control over Internet routing decisions to the
network edge. http://www.routescience.com
