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

[0045] see figure 1 and figure 2 , when the PW link fails, that is, PE1 does not receive the Hello packet from PE2, or receives the Hello packet with the DOWN status bit from PE2, it needs to notify the AC link of the fault detection result. Proceed as follows:

[0046] Step 101: Create a linearly indexed PW and AC state table in the public data area on PE1 and PE2 respectively, and associate the indexes of the state table with the instance tables corresponding to BFD detection and ETHOAM detection;

[0047] Step 102: Use BFD detection technology to detect the link PW, and detect that the link between PE1 and PE2 is faulty;

[0048] Step 103: The PE searches the corresponding PW and AC state table according to the state table index on the BFD detection instance table, and sets the PW state bit therein as DOWN;

[0049] Step 104: Use the ETHOAM detection technology to detect the AC link, the PE searches the corresponding PW and AC state table according to the state table in...

Embodiment 2

[0052] see figure 1 and 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). The specific steps are as follows:

[0053] Step 201: Create a linearly indexed PW and AC state table in the public data area on PE1 and PE2 respectively, and associate the indexes of the state table with the instance tables corresponding to BFD detection and ETHOAM detection;

[0054] Step 202: Use the ETHOAM detection technology to detect the remote AC link, and detect that the link between PE2 and CE2 is faulty:

[0055] Step 203: PE2 searches the corresponding PW and AC state table according to the index of the PW and AC state table on the ETHOAM detection instance table, and sets the AC state bit in the state table to DOWN;

[0056] Step 204: Use the BFD detectio...

Embodiment 3

[0063] see figure 1 and Figure 4 , when the PW link fails, that is, PE1 does not receive the Hello packet from PE2, or receives the Hello packet with the status bit DOWN from PE2, and notifies the AC link of the fault detection result, the specific steps as follows:

[0064] Step 301: Add the index of the BFD detection instance table and the PW status bit in the ETHOAM detection instance table of the AC link;

[0065] Step 302: Add the index of the ETHOAM detection instance table and the AC status bit in the BFD detection instance table of the PW link;

[0066] 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 the corresponding ETHOAM according to the index of the ETHOAM detection instance table in the BFD detection instance table Detect the instance table, and set the PW status bit in the ETHOAM detection instance table to DOWN;

[0067] Step 304: Use the ETHOA...

Abstract

The invention discloses a method and device for intercommunicating network failure detection results, belonging to the network management field, giving a method of establishing state relation between two adjacent links and corresponding the state relation to detection instance list of corresponding links, effectively solving the intercommunicating problem of network failure detection results. And the device implements intercommunication of network failure detection results.

Description

technical field [0001] The invention relates to the field of network management, in particular to a method and device for intercommunicating network fault detection results. Background technique [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 The maintainability and operability are relatively weak. As the scope of Ethernet promotion gradually expands, the demand for Ethernet OAM (Operations, Administration and Maintenance, operation, management and maintenance) functions becomes stronger and 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 eliminate the n...
