US Patent 8023504 Integrating security server policies with optimized routing control

In one embodiment, a first set of one or more control policies at a control server of a network domain may be transmitted to a routing master controller of the network domain, which uses a second set of one or more traffic policies to determine optimal paths for directing traffic through the domain. The routing master controller may then generate a third set of one or more integrated policies based on the first and second sets of policies, e.g., based on the knowledge and policies of both the control server and the routing master controller.
