Abstract
A controller may identify a problematic path from several paths over which to route egress traffic from a site, may determine a threshold amount of traffic to shift from the problematic path, and may implement different potential traffic shifts for shifting similar amounts of traffic as the threshold amount. The controller may provide the labels or header values that different nodes in the site may place in the egress traffic in order to control which path is used to distributed that egress traffic. The controller may modify routing policies affecting different Autonomous System numbers, address prefixes, or other routing parameters to select and/or shift egress traffic, that is associated with those routing parameters and that is about equal to the threshold amount of traffic, from the problematic path to a different path.
