The present disclosure relates to the field of computers, and particularly relates to a failure processing method and apparatus, and a storage medium.
For the reliability of the network, the operation administration and maintenance (OAM) technology has been widely applied to the access layer, the convergence layer, the core layer of the network. OAM provides a series of functions of failure detection, failure verification and failure location. Two devices deployed with OAM need to be separately provided with maintenance end points (MEPs) for providing a function of failure detection.
It is defined in the ITU-T Y.1731 standard that connectivity between the MEPs is checked by regularly sending a continuity check message (CCM) to each other, and when one MEP does not receive the CCM sent by the other MEP within a certain time, the link is assumed to have failed.
Some devices, which are outside the CCM detection range and do not have the function of link detection, can be informed about the link state by means of a CSF. In an exemplary scenario, an OAM function is deployed between device A and device B, and a link state is detected through the CCM; no OAM function is deployed between device C and device A; and an OAM function is deployed between device B and device C. In this scenario, when the link between device A and device B has a failure, device B can detect this failure and inform device C of this failure through a CSF message, and then device C can know that the link on the other side of device B has a failure so as to take a countermeasure.
There is currently no effective solution to the above problems in the related art.
The embodiments of the present disclosure provide a failure processing method and apparatus, and a storage medium, which may at least solve the problems of higher software complexity and a low efficiency due to the fact that after an MEP on a device detects a link failure, CPU intervention is required for sending a CSF message in the related art.

In some exemplary implementations of the embodiment, triggering the second MEP associated with the first MEP to send the CSF message includes: determining whether the first MEP is linked with the CSF message; searching, under a condition that the first MEP is linked with the CSF message, an index of the second MEP from a field index of the first MEP; and triggering, after the index of the second MEP is found, the second MEP to send a CSF message
In some exemplary implementations of the embodiment, the method may further include: continuing to execute, under a condition that the link state indicates a failure, the operation of acquiring the link state detected by the first MEP by means of the CCM.
In some exemplary implementations of the embodiment, acquiring the link state detected by the first MEP by means of the CCM includes: periodically acquiring the link state detected by the first MEP by means of the CCM.

According to yet another aspect of the embodiments of the present disclosure, provided is a storage medium, wherein the storage medium stores a computer program, the computer program being configured to execute the method at runtime.
According to the embodiments of the present disclosure, under a condition that an acquired link state detected by a first MEP by means of a CCM indicates a failure, a second MEP associated with the first MEP is triggered to send a CSF message, so as to avoid triggering a CSF message by CPU intervention in the case of a failure and solve the problems of higher software complexity and a low efficiency due to the fact that after an MEP on a device detects a link failure, CPU intervention is required for sending a CSF message in the related art, thereby improving the efficiency.
The accompanying drawings described herein serve to provide a further understanding of the present disclosure and form a part hereof, and the illustrative embodiments of the present disclosure and the description of the illustrative embodiments serve to explain the present disclosure and are not to be construed as unduly limiting the present disclosure. In the drawings:
The present disclosure will be described in detail below with reference to the accompanying drawings in conjunction with embodiments. It should be noted that the embodiments of the present disclosure and the features of the embodiments may be combined with each other without conflict.
It should be noted that the terms “first”, “second”, etc., in the description and claims of the present disclosure and in the above-mentioned drawings, are used to distinguish between similar objects and not necessarily to describe a particular order or sequential order.
Provided in this embodiment is a failure processing method.
S202, acquiring a link state detected by a first MEP by means of CCM; and
S204, triggering, under a condition that the link state indicates a failure, a second MEP associated with the first MEP to send a CSF message.
By means of S202 and S204, under a condition that the acquired link state detected by the first MEP by means of the CCM indicates a failure, the second MEP associated with the first MEP is triggered to send a CSF message, so as to avoid triggering a CSF message by CPU intervention in the case of a failure and solve the problems of higher software complexity and a low efficiency due to the fact that after an MEP on a device detects a link failure, CPU intervention is required for sending a CSF message in the related art, thereby improving the efficiency.
In an exemplary implementation of the embodiment, a mode of triggering the second MEP associated with the first MEP to send the CSF message involved in S204 of the embodiment may be implemented by means of the following operations:
S204-11, determining whether the first MEP is linked with the CSF message;
S204-12, searching, under a condition that the first MEP is linked with the CSF message, an index of the second MEP from a field index of the first MEP; and
S204-13, triggering, after the index of the second MEP is found, the second MEP to send a CSF message.
The implementation of the above S204-11 to S204-13 in an exemplary application scenario is described as follows. First, the following fields are defined in the first MEP:
auto_csf_en; //indicates whether CSF is linked; and
csf_mep_index; //indicate an index of the MEP for which a CSF function is configured.
The following field is defined in the second MEP:
csf_en; //indicates a function enabling csf message sending.
Based on the above definition, the process flow of triggering sending of the CSF message is as follows.
The first MEP detects the link state, and under a condition that the link has a failure, whether auto_csf_en is 1 is determined; under a condition that auto_csf_en is 1, information of the second MEP is read according to csf_mep_index; and under a condition that csf_en of the second MEP is 1, a csf message is sent. That is, after the MEP running the CCM detects a link failure, another associated MEP may be directly triggered to directly send the CSF message, which reduces exchange with a CPU, and therefore improves the efficiency.
In another exemplary implementation of the embodiment, the method in the embodiment may further include:
S206, continuing to execute, under a condition that the link state indicates a failure, operation of acquiring the link state detected by the first MEP by means of the CCM.
The operation of acquiring the link state detected by the first MEP by means of the CCM in this embodiment may be: periodically acquiring the link state detected by the first MEP by means of the CCM. The period can be correspondingly set according to a situation, and the specific time value of the period is not limited in the embodiment.
In yet another exemplary implementation of this embodiment, the method of the embodiment includes the operation of: establishing, prior to acquiring the link state detected by the first MEP, an association between the first MEP and the second MEP.
