Abstract:
1. A method for dynamically enforcing a best exit selection for a controlled prefix based on policies and real-time performance statistics in a computer network, the method comprising: selecting, by a processor, a best exit for the controlled prefix; in response to selecting the best exit for the controlled prefix, performing a parent lookup that looks to a parent prefix of the controlled prefix, to determine whether the controlled prefix is reachable via the selected best exit; if so, influencing a route for the controlled prefix to be over the selected best exit; in response to the influencing the route, verifying if traffic flow for the controlled prefix is directed over the selected best exit; and in the event that the traffic flow is not directed over the selected best exit, further influencing the route for the controlled prefix to be over the selected best exit or removing any attempted influences on the route for the controlled prefix to be over the selected best exit.
