Embodiment 1

[0023] Such as figure 2 As shown, it is a schematic flow chart of the MPLS-TP ring network troubleshooting method described in Embodiment 1 of the present invention, and the MPLS-TP ring network troubleshooting method may include the following steps:

[0024] Step 201: After the network device receives the forwarding fault notification message sent by the fault detection device indicating that the network device has a forwarding fault, it detects one of the entry for generating the forwarding table learned by the MPLS process, the software forwarding table, and the hardware forwarding table Whether the number of table entries is consistent.

[0025] Wherein, it should be noted that the forwarding failure of the network device only means that the network device has a forwarding problem, but the network device can also communicate with other devices (for example, by using IP or Ethernet communication).

[0026] Wherein, in one embodiment, the MPLS process is responsible for th...

Embodiment 2

[0062] Below, the MPLS-TP ring network troubleshooting method provided by the embodiment of the present invention is described with a specific embodiment, such as image 3 Shown: There are two communication paths between network devices S1 and S4, one is S1->S2->S3->S4 (denoted as the first communication path); the other is S1->S5->S6-> S7->S4 (denoted as the second communication path); wherein, the first communication route is the preferred communication path. When the two communication paths are not faulty, S1 and S4 communicate through the first communication path. Later, the first communication path fails, and S1 and S4 switch to the second communication path for communication. In this application scenario, the MPLS-TP ring network troubleshooting method of the embodiment of the present invention, such as Figure 4 shown, including the following steps:

[0063] Step 401: After the fault detection device detects that the network device S3 has a forwarding fault through t...

Embodiment 3

[0074] Based on the same inventive concept, the embodiment of the present invention also provides an MPLS-TP ring network troubleshooting device, such as Figure 5 Shown is a schematic structural diagram of the device, which includes:

Abstract

The invention discloses a MPLS‑TP ring network troubleshooting method and device. In this solution, the network device detects the MPLS process learning after receiving the forwarding fault notification message sent by the fault detection device, indicating that the network device has a forwarding fault. Whether the number of entries used to generate the forwarding table, the software forwarding table and the hardware forwarding table are consistent; if the number is inconsistent, the MPLS process is used to re-issue and generate the software forwarding table and the hardware forwarding table. This solution can eliminate faults without manual intervention, can improve the efficiency of communication path recovery, and ensure that the communication path is available, so as to ensure that the communication between the two parties is not interrupted.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to an MPLS-TP (Transport Profile for MPLS, connection-oriented packet switching network technology) ring network troubleshooting method and device. Background technique [0002] MPLS-TP technology, which combines the advantages of MPLS (Multi-Protocol Label Switching, Multi-Protocol Label Switching) technology and SDH (Synchronous Digital Hierarchy, Synchronous Digital Hierarchy) technology, adds connection-oriented features to traditional packet networks, increases Carrier-level performance detection and OAM (Operation Administration and Maintenance, operation, maintenance and management) functions complement and improve the QoS (Quality of Service, quality of service) mechanism and end-to-end service deployment capabilities, so as to provide carrier-class transmission functions. [0003] In MPLS-TP, reliability is a key indicator. In actual deployment, the MPLS-TP ri...
