Embodiment 1

[0039] The pseudo-wire dual-homing protection management method provided in this embodiment is mainly applied to pseudo-wire dual-homing protection communication equipment. The pseudo-wire dual-homing protection communication equipment includes a main control board and a line card; Control board communication connection; for the method, please refer to image 3 shown, including:

[0040] Step 301: When the line card detects an alarm on the active pseudowire link currently in working state, switch to the standby pseudowire link;

[0041] In this step, after an alarm is detected on the active PW link, or after the line card is switched to the standby PW link, the corresponding alarm notification can be sent directly to the main control board; Temporarily send an alarm notification to the main control board, but wait for the subsequent judgment that the alarm is not a false alarm before sending an alarm notification to the main control board;

[0042] Switching to the standby pse...

Embodiment 2

[0059] This embodiment provides a pseudowire dual-homing protection communication device, please refer to Figure 5 As shown, it includes the main control board 2 and the line card 1; the line card 1 is used to switch to the standby pseudo-wire link when it detects an alarm on the main pseudo-wire link currently in working state; and is used to switch to the standby pseudo-wire link After connecting the pseudowire link, judge whether the alarm is a false alarm. If so, switch back to the main pseudowire link directly from the standby pseudowire link.

[0060] Line card 1 can specifically detect whether the link is faulty through BFD, MPLS OAM and other detection mechanisms; in this step, switching to the standby pseudo-line link mainly refers to the service forwarding plane of line card 1. After the line card detects an alarm, the main pseudo-line Switch the wired link to the standby pseudowire link to ensure the normal forwarding of business data as much as possible;

Abstract

The invention discloses a pseudowire dual-homing protection management method and a communication device. When the line card of the communication device detects that an alarm occurs on the main pseudowire link currently in the working state, it switches from the active pseudowire link to the backup pseudowire Then judge whether the alarm is a false alarm, if it is judged to be a false alarm, then directly switch back to the main pseudo-wire link from the standby pseudo-wire link; Perform a switchback operation, so it can be consistent with the pseudo-wire protection status on the line card side.

Description

technical field [0001] The invention relates to the field of communication, in particular to a pseudowire dual-homing protection management method and communication equipment. Background technique [0002] In the MPLS (Multiprotocol Label Switching) communication network, L2VPN (Virtual Private Network, Virtual Private Network) provides Layer 2 VPN services based on MPLS networks, enabling operators to provide different data link-based VPN services on a unified MPLS network. Layer 2 VPN, including ATM, FR, VLAN, Ethernet, PPP, etc. Simply put, MPLS L2VPN transparently transmits user Layer 2 data on the MPLS network. From the user's point of view, the MPLS network is a Layer 2 switching network, which can establish Layer 2 connections between different nodes. [0003] If only one PW (PseudoWire) is established between two PEs (Provider Edges), when the PW fails, the PEs will not be able to communicate. MPLS L2VPN supports PW redundancy protection function: L2VPN-FRR is als...
