Problems solved by technology

[0002] Ethernet technology is easy to use, low in price, and its bandwidth can be continuously improved. Whether it is a service or a network structure, it has been widely used in enterprise networks, metropolitan area networks, and wide area networks. However, traditional Ethernet Maintainability and operability are relatively weak. With the gradual expansion of the scope of Ethernet promotion, the demand for Ethernet OAM (Operations, Administration and Maintenance, operation, management and maintenance) functions is also becoming stronger and stronger.

Embodiment 1

[0032] See figure 1 with figure 2 When the PW link fails, that is, PE1 does not receive the Hello message from PE2, or receives the Hello message from PE2 with the status bit as DOWN, it needs to notify the AC link of the failure detection result. Proceed as follows:

[0033] Step 101: Create a linearly indexed PW and AC state table in the common data area on PE1 and PE2, and associate the indexes of the state table to the instance tables corresponding to BFD detection and ETHOAM detection respectively;

[0034] Step 102: Use BFD detection technology to detect the link PW, and detect that the link between PE1 and PE2 is faulty;

[0035] Step 103: The PE searches for the corresponding PW and AC state tables according to the state table index on the BFD detection instance table, and sets the PW state bit therein to DOWN;

[0036] Step 104: Use the ETHOAM detection technology to detect the AC link. The PE searches for the corresponding PW and AC state tables according to the state ta...

Embodiment 2

[0039] See figure 1 with image 3 , When the remote AC link (the link between PE2 and CE2) fails, that is, PE2 does not receive the CCM message from CE2, or receives the CCM message with the RDI flag from CE2, it will The fault detection result is notified to the near-end AC link (the link between PE1 and CE1), and the specific steps are as follows:

[0040] Step 201: Create a linearly indexed PW and AC state tables in the common data areas on PE1 and PE2, and associate the indexes of the state tables with the instance tables corresponding to BFD detection and ETHOAM detection respectively;

[0041] Step 202: Use the ETHOAM detection technology to detect the remote AC link, and detect that the link between PE2 and CE2 is faulty;

[0042] Step 203: PE2 searches for the corresponding PW and AC state tables according to the indexes of the PW and AC state tables on the ETHOAM detection instance table, and sets the AC state bit in the state table to DOWN;

[0043] Step 204: Use the BF...

Embodiment 3

[0050] See figure 1 with Figure 4 , When the PW link fails, that is, PE1 does not receive the Hello message from PE2, or receives the Hello message from PE2 with the status bit as DOWN, it will notify the AC link of the failure detection result. The specific steps are as follows:

[0051] Step 301: Add the index of the BFD detection instance table and the PW status bit to the ETHOAM detection instance table of the AC link;

[0052] Step 302: Add the index of the ETHOAM detection instance table and the AC status bit to the BFD detection instance table of the PW link;

[0053] Step 303: Use the BFD detection technology to detect the link PW, and detect that the link between PE1 and PE2 is faulty, and PE1 and PE2 respectively search for their corresponding ETHOAM according to the index of the ETHOAM detection instance table in the BFD detection instance table Check the instance table, and set the PW status bit in the ETHOAM detection instance table to DOWN;

[0054] Step 304: Use t...

Abstract

The invention discloses a method and a device for intercommunicating network fault detection results, belonging to the field of network management. In order to solve the problem of intercommunication of network fault detection results, the present invention proposes a method of establishing the state association of two adjacent links, and corresponding the association to the detection instance table of the corresponding link. The method effectively solves the problem of intercommunication of network fault detection results. The invention also provides a network fault detection result intercommunication device, which also realizes the problem of network fault detection result intercommunication.

Description

Technical field [0001] The invention relates to the field of network management, in particular to a method and device for intercommunication of network fault detection results. Background technique [0002] Ethernet technology is simple and easy to use, low in price, and bandwidth can be continuously improved. Whether as a business or as a network structure, it has been widely used in enterprise networks, metropolitan area networks, and wide area networks. However, traditional Ethernet Maintainability and operational capabilities are relatively weak. With the gradual expansion of the scope of Ethernet promotion, the demand for Ethernet OAM (Operations, Administration and Maintenance, operation, management and maintenance) functions is becoming stronger. OAM technology is a technology that provides operable and maintainable functions. It can automatically detect various failures in the network, and then take corresponding remedial measures to avoid the expansion of the failure or ...
