Method and Device for Link Protection in Virtual Private Local Area Network

A device for a link protection in a virtual private local area network, comprising a platform protocol processing module, a table entry writing processing module and a data forwarding processing module, wherein:

• the platform protocol processing module is configured to, in a networking process of a virtual private local area network services (VPLS) network, establish a main tunnel and a standby tunnel of multi-protocol label switching (MPLS) traffic engineering (TE) for a link;
• the table entry writing processing module is configured to create a VPLS forwarding table to organize information of the MPLS TE main tunnel and standby tunnel established by the platform protocol processing module;
• and
• the data forwarding processing module is configured to, when receiving a VPLS network message, search the information of the MPLS TE main tunnel of transmitting the VPLS network message according to a way of accessing the VPLS network of the VPLS network message and the created VPLS forwarding table, and if the found MPLS TE main tunnel is invalid, then transmit the received VPLS network message by adopting the standby tunnel of the MPLS TE main tunnel.
