Abstract
In one embodiment, a method includes receiving packet flow optimization (PFO) configuration data that associates each rule name of multiple PFO rule names with a corresponding method for processing a data packet in a communications network based on data in a payload of a layer 3 protocol of the data packet. A first policy message is received from a policy management process in the communications network. The first policy message includes rule data that indicates a signaled rule name associated with a particular network address in the communications network. In response to receiving the first policy message, a data packet of the particular network address is processed according to a particular method associated with a particular rule name selected based on the signaled rule name. As a result, a PFO policy is controlled from the policy management process.
