Abstract
IP applications may be hosted on processors other than the processor on which their associated routing entity is hosted by causing the routing context to be extended to the new processor and causing IP termination to occur at the new processor. Applications may define policies specifying packet attributes and actions to be taken on matching packets, so that packets matching the policy may be directed to a processor hosting the application rather than a processor hosting the routing entity. A steering policy manager may be implemented to receive policies from the applications, verify the policy format and uniqueness vis-à-vis previously implemented policies, and implement the policies by passing the policies to one or more steering policy agents. Filters may be programmed into the data plane or the control plane to cause IP termination to occur on the processor hosting the application.
