Methods, systems, and computer readable media for providing policy and charging rules function (PCRF) with integrated openflow controller

摘要

The subject matter described herein includes methods, systems, and computer readable media for providing a PCRF with an integrated openflow controller. According to one system, a policy and charging rules function (PCRF) is configured to determine policies to apply to network sessions or users. An openflow controller is integrated with the PCRF and configured to provide instructions to telecommunications network elements in an openflow protocol to implement the policies.

主权项

1. A system for providing a policy controlling network, the system comprising:
a policy and charging rules function (PCRF) configured to determine policies to apply to network sessions or users, wherein the PCRF is configured to receive, from a broadband remote access server/broadband network gateway (BRAS/BNG), an initial frame or packet to determine what policy to apply to subsequent frames or packets associated with the same flow as the initial frame or packet; and an openflow controller integrated with the PCRF and configured to provide instructions to telecommunications network elements in an openflow protocol to implement the policies, wherein the PCRF with the integrated openflow controller comprises an openflow-enabled PCRF that controls nodes using the openflow protocol, wherein the openflow controller receives the initial frame or packet, determines the policy to apply to the subsequent frames or packets and sends an openflow command to the BRAS/BNG to add an entry to a flow table of the BRAS/BNG to implement the policy for the subsequent frames or packets associated with the same flow as the initial frame or packet.
