Abstract
Disclosed are, inter alia, methods, apparatus, computer-storage media, mechanisms, and means for transportation of IEEE 802.1ah frames over Multiprotocol Label Switching (MPLS) pseudowires for Virtual Private LAN Services (VPLS). The IEEE 802.1ah frames include a corresponding B-VLAN tag, while the MPLS packets including these frames do not include the corresponding B-VLAN tag, and disclosed are methods and apparatus for performing such translation.
