Access method and apparatus for multi-protocol label switching layer 2 virtual private network
First Claim
1. An access method for a Multi-protocol Label Switching Layer 2 Virtual Private Network (MPLS L2VPN), comprising:
- making, by a customer side and a network side, their respective messages access operator routing equipment, setting access types of the messages to be mapped to virtual ports, and respectively allocating their respective Source Virtual Ports (SVP) and Destination Virtual Ports (DVP) to each access; and
establishing, by the customer side and the network side, a data forwarding channel of the MPLS L2VPN by establishing connection from their respective SVPs to DVPs of opposite sides.

Abstract
An access method and apparatus for a MPLS L2VPN are described. The method includes that a customer side and a network side sends their respective message to an operator routing equipment, set the access types of the messages to be mapped to virtual ports, and respectively allocate their respective Source Virtual Ports (SVP) and Destination Virtual Ports (DVP) to each access, and establish a data forwarding channel of the MPLS L2VPN by respectively establishing connection from their own SVP to the DVP of the opposite side. With the disclosure, various access modes are uniformly mapped to virtual ports, and then the MPLS L2VPN is accessed; furthermore, forwarding can be performed based on a Virtual Switch Interface (VSI) and virtual ports.

9. An access apparatus for a Multi-protocol Label Switching Layer 2 Virtual Private Network (MPLS L2VPN), comprising a control module and a connection establishing module, wherein
the control module is configured to respectively make a message of a customer side and a message of a network side access operator routing equipment, set access types of the messages to be mapped to virtual ports, allocate respective Source Virtual Ports (SVP) and Destination Virtual Ports (DVP) of the customer side and the network side to each access, and send information of the virtual ports after allocation to the connection establishing module; - and
the connection establishing module is configured to establish a data forwarding channel of the MPLS L2VPN by respectively establishing connection from the SVP of the customer side to the DVP of the network side and connection from the SVP of the network side to the DVP of the customer side, according to the information of the virtual ports after allocation which is sent by the control module. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
