ABSTRACT:
Systems and methods are provided to implement a dynamic and efficient cascading policy management framework architecture for both wired and wireless networks. A plurality of Policy Functions (PFs) are assigned to a plurality of Policy Enforcement Points (PEP). The PFs make decisions regarding local policy control at the specific PEP. The PFs then delegate the policy requests or IP flows to a separate PEP that is more conducive to enforcing that policy request. Thus, policy decisions are made at the point where the most information is available, leading to fewer policy requests traversing back and forth across a network. Additionally, this cascading Policy Management Framework Architecture allows for unified policy management across multiple types of networks, including wired (Internet) and wireless (UMTS).
