Re: Split flows across Domains

For example, an ISP can learn two different equal cost routes to a foo.com server via two different autonomous domains. It can thus split different flows (based on src-dest IP, src-dest Port, TOS, etc) across these two paths.

Do operators currently do this?

Folks can send me replies offline in case this constitues a "trade secret"!

Works great with a flow-based router (or layer-three-switch-pronounced- 'crippled-router'). The downside, of course, is that you now have a flow-based router in your network, which has been shown to Not Work Well under other specified conditions (worm outbreaks come immediately to mind). ---rob
