  • Continuous Virtual Private Local Area Network (LAN) Service (VPLS) Over Wireline and Wireless Networks
    Publication number: 20130308617
    Abstract: A mechanism is provided for enabling virtual private local area network (LAN) service (VPLS) service within a base station (NodeB/eNodeB). A wireless signal is received from a mobile device. The wireless signal is converted into one or more internet protocol (IP) packets. A VPLS virtual private network (VPN) multiprotocol label switching (MPLS) label is constructed in a header of each IP packet. An egress router is identified for the IP packets. A MPLS label of the egress router is constructed for MPLS routing. The MPLS label is added on top of the VPLS VPN MPLS label in the header of each IP packet. The one or more IP packets are then forwarded to at least one other router within a MPLS network.
