Abstract

A method is provided in one example embodiment and includes receiving a data packet transported on a backhaul link at a first network element; identifying whether the data packet is an upstream data packet; identifying whether the data packet matches an internet protocol (IP) access control list (ACL) or a tunnel endpoint identifier; performing a network address translation on the data packet; and offloading the data packet from the backhaul link. In certain implementations, the method can include identifying that the data packet does not match the IP ACL or the tunnel endpoint identifier; and communicating the data packet to a second network element. In other instances, the method can include identifying that the data packet is a downstream data packet; and restoring a tunnel header and tunnel identification based on an IP address of the data packet.
