Abstract
Embodiments of a method and system for enforcing a traffic policy at a Policy Enforcement Point (PEP) that controls the flow of traffic in a wireless communications network are described. In one embodiment, a method involves learning the topology of the wireless communications network, defining a virtual PEP (VPEP) within the topology of the wireless communications network, the VPEP comprising a location component that is remote from the PEP, associating a traffic policy with the VPEP, associating a traffic flow with the VPEP if the traffic flow has a characteristic that corresponds to the location component of the VPEP, and enforcing, at the PEP, the traffic policy that is associated with the VPEP against the traffic flow.
