IMPLEMENTING METHOD AND DEVICE FOR VIRTUAL LOCAL AREA NETWORK STACK ACCESSING VIRTUAL PRIVATE WIRE SERVICE

摘要

The present invention discloses an implementation method for a Virtual Local Area Network Stacking (QINQ) accessing a Virtual Private Wire Service (VPWS), including: setting a self-loop port of a switch; modifying an original Multi-Protocol Label Switching (MPLS) configuration of the switch, so that an MPLS label is stripped from an MPLS packet which enters through a network side port to obtain a QINQ packet and then send through the self-loop port, and replacing an outer Virtual Local Area Network (VLAN) label of the QINQ packet with an arbitrary value; replacing the two layers of VLAN labels of the QINQ packet with the two layers of VLAN labels of the user side port according to a corresponding relation between the arbitrary value and the two layers of VLAN labels of the user side port; redirecting the QINQ packet to the user side port according to a corresponding relation between the two layers of VLAN labels of the user side port and the user side port. With the present invention, a replacement of the two layers of VLAN labels of the QINQ packet can be implemented.
