Abstract:
A VPLS model is implemented in a network-facing provider edge (n-PE) device configured to receive a packet from an access network the packet having a first Virtual Local Area Network (VLAN) tag of a first predetermined bit length The n-PE device mapping the service instance identifier of the first VLAN tag into a second VLAN tag of a second predetermined bit length greater than the first predetermined bit length, the second VLAN tag identifying a Virtual Private LAN Service (VPLS) instance The n-PE device then sends the packet with the second VLAN tag across a service provider (SP) core network via a pseudowire (PW) that functions as a logical link to another PE device
Abstract:
A method of operation for a provider edge device of a core network includes receiving a customer frame from an access network; the customer frame having a first Virtual Local Area Network (VLAN) tag of a first predetermined bit length. The first VLAN tag including a service instance identifier. The service instance identifier of the first VLAN tag is then mapped into a second VLAN tag of a second predetermined bit length greater than the first predetermined bit length. 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.
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 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).
Abstract:
A system and method for identifying and forwarding traffic to/from Digital Subscriber Line Access Multiplexer (DSLAM) devices and feature servers without ambiguity includes a user-facing provider edge (u-PE) device that receives a customer frame from a DSLAM device, the customer frame being of a first format that includes a first Virtual Local Area Network (VLAN) tag of a first bit length. The first VLAN tag identifies a Digital Subscriber Line (DSL) subscriber. The customer frame is re-formatted by the u-PE device such that the first VLAN tag is mapped to a second VLAN tag of a second bit length greater than the first bit length, the second VLAN tag identifying a service instance of the Ethernet access network. The u-PE device encapsulating the customer frame inside a provider frame, with a provider source Media Access Control (MAC) address represents a MAC address associated with the DSLAM, and a provider destination MAC address represents a MAC address of a destination device. 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 172(b).
