METHODS, SYSTEMS, AND COMPUTER READABLE MEDIA FOR USING POLICY KNOWLEDGE OF OR OBTAINED BY A POLICY AND CHARGING RULES FUNCTION (PCRF) FOR NEEDS BASED FORWARDING OF BEARER SESSION TRAFFIC TO NETWORK NODES
The subject matter described herein includes methods, systems, and computer readable media for using policy knowledge of or obtained by a policy and charging rules function (PCRF) for needs based forwarding of bearer session traffic to network nodes. One exemplary system includes a PCRF. The PCRF includes a policy engine for identifying, using policy knowledge or obtained by the PCRF, zero or more network nodes hosting applications needed for processing packets of a bearer session. The PCRF further includes an application routing configurator for providing instructions to configure at least one configurable network element to forward bearer session traffic to any of the network nodes determined to be needed for processing packets associated with the bearer session and to bypass any of the network nodes not determined to be needed for processing packets associated with the bearer session.
