ABSTRACT:
A DSLAM aggregation topology VLAN bundling mechanism includes an edge device port that receives a packet from a Digital Subscriber Line Access Multiplexer (DSLAM) device, the packet including an inner Virtual Local Area Network (VLAN) tag that identifies a Digital Subscriber Line (DSL) subscriber. A processor of the edge device adds an outer VLAN tag to the packet, the outer VLAN tag identifying the DSLAM and a destination server coupled to an Ethernet access network. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b).
