Title:

IDENTIFYING NATed DEVICES FOR DEVICE-SPECIFIC TRAFFIC FLOW STEERING

Document Type and Number:

WIPO Patent Application WO/2014/080364

Kind Code:

A1

Abstract:

The present disclosure describes methods and apparatus for differentiating subscriber devices of a subscriber hidden by a network address translation device and enables traffic flow steering on a per device basis rather than a per subscriber basis. Identification of subscriber devices is achieved by assigning a reserved set of external ports to each subscriber device. Different service paths can be defined for different subscriber devices to provide a subscriber with a different experience for each subscriber device of the subscriber.
