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.
