[0025] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0026] After analysis, the inventors of the present application found that in transmission, multiple logical transmissions of different virtual levels can often be multiplexed, and these logical transmissions can form logical transmission protection rings of different virtual levels. Taking optical fiber as an example, a physical optical fiber can carry TMS (Transmission MPLS Section), each TMS can include at least one TP (Transport Protocol), and each TP can also include at least one PW (Pseudo Wire). When any logical transmission protection ring (such as the logical transmission protection ring at the TP application layer) fails, the transmission protection method in the related art will also trigger the service switching of the entire physical transmission protection ring (such as the optical fiber protection ring), causing the services carried by other logical transmission protection rings without failure to switch together, resulting in a huge waste of transmission resources and a certain degree of impact on the service. The present application proposes a method for handling transmission link failures, which can switch services to the target protection ring of the same virtual layer, ensure the normal transmission of services carried on the faulty protection ring, and at the same time avoid triggering service switching of the entire physical transmission link when part of the logical transmission link fails, avoid the impact of service switching on services carried on other logical protection rings, reduce the waste of transmission resources, and improve the utilization rate of transmission resources.

[0027] Figure 3 shows a flow chart of a method for handling a transmission link failure provided by an embodiment of the present application, which can be executed by a network element device or a network management device connected to the network element device. As shown in Figure 3, the method can include the following steps.

[0028] In step S101, the fault information of the transmission link is obtained.

[0029] The fault information includes fault protection ring information of the transmission link. The transmission link includes at least two virtual layers, each virtual layer includes at least one protection ring, and each protection ring of the upper virtual layer includes at least one protection ring of the lower virtual layer.

[0030] In some embodiments, the transmission link may be a fiber ring, and the virtual layer may include a TMS management layer and a TP application layer, wherein the TMS management layer may be an upper-level virtual layer of the TP application layer, and the TMS management layer may include a first protection ring, and the first protection ring may include at least two second protection rings of the TP application layer.

[0031] In another embodiment, the virtual layer may further include a PW application layer, wherein the TP application layer is an upper-level virtual layer of the PW application layer, and each second protection ring includes at least two third protection rings of the PW application layer.

[0032] Figure 4 shows a schematic diagram of the logical structure of a transmission link protection ring provided by an embodiment of the present application. As shown in Figure 4, taking a fiber ring as an example, the TMS management-level protection ring 1 may include a first TP application-level protection ring 11 and a second TP application-level protection ring 12. The first TP application-level protection ring 11 may include a first PW application-level protection ring 111 and a second PW application-level protection ring 112. The second TP application-level protection ring 12 may include a third PW application-level protection ring 121 and a fourth PW application-level protection ring 122.

[0033] Those skilled in the art can flexibly set the number of virtual layers according to the type of transmission link and business needs, and can also flexibly set the number of logical protection rings contained in each virtual layer. Still taking the optical fiber ring as an example, the number of TMS management layer protection rings, TP application layer protection rings and PW application layer protection rings can be flexibly set according to business needs. For example, each TMS management layer protection ring can include only 1 TP application layer protection ring, and each TP application layer protection ring can include 3 PW application layer protection rings; each TMS management layer protection ring can also include 3 TP application layer protection rings, and each TP application layer protection ring can include 2 PW application layer protection rings. This application does not limit this. It should be noted that although TMS, TP and PW in optical fiber transmission are used as examples of protection rings of different virtual layers, this should not be used as a limitation of the protection rings in the technical solution of this application. It can be applied to protection rings of other different types of virtual layers, and can also be applied to transmission link protection rings in other transmission scenarios.

[0034] In step S102, a first target virtual level corresponding to the fault protection ring is determined according to the fault information.

[0035] For example, a transmission link failure may be a failure corresponding to protection rings of different virtual layers, and the reasons for the failure may be various, such as any physical optical fiber interruption, any virtual layer logical protection ring connection interruption, or any virtual layer logical protection ring connection bit error rate exceeding a preset threshold. The corresponding virtual layer may be included in the fault information. Taking the optical fiber protection ring as an example, when the logical connection of a virtual layer in the protection ring fails, thereby causing the protection ring of the virtual layer to fail, the fault information may include the first target virtual layer corresponding to the failed protection ring. For example, in optical fiber transmission, if the logical connection of the layer between any two network elements in the first TP application layer protection ring 11 fails, the first TP application layer protection ring 11 will fail. The first target virtual layer of the first TP application layer protection ring 11 may be, for example, Level2, where Level2 is used to characterize that the virtual layer of the first TP application layer protection ring 11 is the TP application layer.

[0036] In step S103, a target protection ring for carrying services on the faulty protection ring is determined from the protection rings whose virtual level is the first target virtual level.

[0037] The target protection ring carries services on the fault protection ring during a transmission link failure, and the corresponding virtual layer is a protection ring of the first target virtual layer, ie, a protection ring of the same level.

[0038] For example, when a fault occurs in the hierarchical logical connection between any two network elements in the first TP application layer protection ring 11, causing the first TP application layer protection ring 11 to fail, the target protection ring can be determined from the protection rings of the same level (i.e., the virtual level of the protection ring is also the first target virtual level Level 2) based on the first target virtual level Level 2 of the first TP application layer protection ring 11.

[0039] When a transmission link fails, multiple fault information at different virtual levels may be generated. For example, when a fault occurs in the first TP application layer protection ring 11, in addition to generating fault information of the first TP application layer protection ring 11, the lower-level protection rings of the first TP application layer protection ring 11 (such as the first PW application layer protection ring 111 and the second application layer optical fiber protection ring 112) may also generate corresponding virtual level Level 3 (i.e., PW application layer) fault information due to the fault in the first TP application layer protection ring 11. In this case, the target protection ring can be determined based on the first target virtual level in the fault information with the highest virtual level among the fault information of multiple different virtual levels.

[0040] In step S104, the service on the faulty protection ring is switched to the target protection ring.

[0041] For example, after determining the target protection ring corresponding to the faulty protection ring, the service on the faulty protection ring may be switched to the target protection ring, so that the service on the faulty protection ring is carried by the target protection ring, thereby improving the reliability of the transmission link.

[0042] Taking fiber transmission as an example, if the first TP application-layer protection ring 11 fails, the target protection ring can be determined to be the second TP application-layer protection ring 12, and services on the first TP application-layer protection ring 11 can be switched to the second TP application-layer protection ring 12. This eliminates the need to switch services on the entire fiber ring to the protection ring. This overcomes the technical problem in related art where switching services on the entire physical fiber ring causes normal logical transmission links (e.g., the second TP application-layer protection ring 12) to also be switched to the protection ring, thereby impacting services on the normal logical transmission links (e.g., the second TP application-layer protection ring 12).

[0043] By adopting the above-mentioned technical method, the service can be switched to the target protection ring of the same virtual layer, ensuring the normal transmission of the service carried on the fault protection ring. At the same time, it can avoid triggering the service switching of the entire physical transmission link when some logical transmission links fail, and avoid the service switching from affecting the services carried on other logical protection rings. It reduces the waste of transmission resources and improves the utilization rate of transmission resources.

[0044] FIG5 shows another flow chart of a method for handling a transmission link failure provided by an embodiment of the present application. As shown in FIG5 , step S103 may include the following steps: in step S1031 , a first candidate protection ring that meets a preset condition is determined from the protection ring whose virtual level is the first target virtual level.

[0045] The preset conditions may include preset state conditions and / or preset capacity conditions.

[0046] In some embodiments, the preset capacity condition may include that the remaining service bandwidth of the protection ring is greater than or equal to the service bandwidth on the fault protection ring; the preset status condition may include at least one of the following: the protection ring's switching permission function is turned on; the service status of the protection ring is activated; the service status of the protection ring on the network management device is consistent with the service status of the protection ring on the network element device.

[0047] Those skilled in the art may also flexibly set at least one of the preset state condition and the preset capacity condition according to business needs, and this application does not impose any restrictions on this.

[0048] In some embodiments, the protection ring of each virtual layer may also include one or more additional information as shown in Table 1 below. In some possible implementations, the fault information may include the above one or more additional information, and the above one or more additional information may also be obtained by the network element device or the network management device connected to the network element device from the configuration information and real-time status information.

[0049] Table 1

[0050] In some embodiments, it may be determined through the additional information whether the protection ring of each virtual level as the first target virtual level meets a preset condition.

[0051] For example, when the fault protection ring is the first PW application layer protection ring 111 , the first candidate protection rings may be the second PW application layer protection ring 112 , the third PW application layer protection ring 121 , and the fourth PW application layer protection ring 122 that meet preset conditions.

[0052] By determining the target protection ring from the first candidate protection rings that have been screened by at least one of a preset state condition and a preset capacity condition, abnormal conditions such as excessive traffic load on the target protection ring can be avoided after switching the traffic on the faulty protection ring to the target protection ring, thereby improving the reliability of transmission link fault handling.

[0053] In step S1032, a target protection ring is determined from the first candidate protection rings.

[0054] In some embodiments, when the number of first candidate protection rings is one, the first candidate protection ring may be determined as the target protection ring.

[0055] In another embodiment, when there are multiple first candidate protection rings, the target protection ring is determined from the first candidate protection rings according to a preset priority order.

[0056] In some possible implementations, a target protection ring may be determined from a plurality of first candidate protection rings according to a preset priority order by any of the following methods.

[0057] Method 1: When a second candidate protection ring exists in the first candidate protection ring, the protection ring with the highest target priority order among the second candidate protection rings is determined as the target protection ring.

[0058] The second candidate protection ring is the same as the upper protection ring to which the fault protection ring belongs, and the highest target priority order includes the lowest service load or the lowest historical failure rate.

[0059] For example, in FIG4 , when the fault protection ring is first PW application-level protection ring 111, and the first candidate protection rings include second PW application-level protection ring 112, third PW application-level protection ring 121, and fourth PW application-level protection ring 122, since second PW application-level protection ring 112 and fault protection ring first PW application-level protection ring 111 belong to the same upper-level protection ring, first TP application-level protection ring 11, the second candidate protection ring can be determined to be second PW application-level protection ring 112, and second PW application-level protection ring 112 can be determined as the target protection ring. If there are multiple second candidate protection rings, the protection ring with the highest target priority can be selected as the target protection ring. The highest target priority indicates the lowest service load or the lowest historical failure rate.

[0060] Method 2: When there is no second candidate protection ring among the first candidate protection rings, determine the protection ring with the highest target priority order among the first candidate protection rings as the target protection ring.

[0061] For example, when the fault protection ring is the first PW application layer protection ring 111, and the first candidate protection ring includes the third PW application layer protection ring 121 and the fourth PW application layer protection ring 122, since the upper-level protection ring of the fault protection ring, the first TP application layer protection ring 11, does not include a protection ring that meets the preset conditions, and since the second candidate protection ring is not included in the first candidate protection ring, the protection ring with the highest target priority order can be selected from the third PW application layer protection ring 121 and the fourth PW application layer protection ring 122 as the target protection ring, and the highest target priority order includes the lowest service load or the lowest historical failure rate.

[0062] In the case where there is a second candidate protection ring, the target protection ring is determined from the second candidate protection ring, and the scope of influence that may be caused by the service switching between the faulty protection ring and the target protection ring can be controlled within the upper-level protection ring of the faulty protection ring, thereby controlling the scope of influence of the service on the transmission link failure processing. Similarly, if the number of virtual levels is greater than the three levels shown in the example of FIG3 , it can be expanded based on the above-mentioned technical approach. In the case where there is no second candidate protection ring, it can continue to determine whether there is a third candidate protection ring from the upper-upper protection ring of the faulty protection ring (i.e., the upper-upper protection ring of the upper-upper protection ring of the faulty protection ring). In the case where there is a third candidate protection ring, the protection ring with the highest target priority order among the third candidate protection rings is determined as the target protection ring. In this way, the scope of influence that may be caused by the service switching between the faulty protection ring and the target protection ring can be controlled within the upper-upper protection ring of the faulty protection ring.

[0063] Those skilled in the art may also flexibly set the target priority order according to business needs, and this application does not impose any restrictions on this.

[0064] By adopting the above-mentioned technical method, the service can be switched to the target protection ring of the same virtual layer, ensuring the normal transmission of the service carried on the fault protection ring. At the same time, it can avoid triggering the service switching of the entire physical transmission link when some logical transmission links fail, and avoid the service switching from affecting the services carried on other logical protection rings. It reduces the waste of transmission resources, improves the utilization rate of transmission resources, and can also control the service impact scope of transmission link fault handling as much as possible, further improving the reliability of transmission link fault handling.

[0065] FIG6 illustrates another flow diagram of a method for handling a transmission link failure according to an embodiment of the present application. As shown in FIG6 , step 104 may include the following steps: In step S1041, services on the failed protection ring are deleted and services are recreated on the target protection ring. In step S1042, the remaining service bandwidth of the target protection ring is updated based on the service bandwidth of the failed protection ring.

[0066] For example, the remaining service bandwidth of the target protection ring may be updated according to the following formula 1.

[0067] in, is the remaining service bandwidth of the updated target protection ring, BW is the remaining service bandwidth of the target protection ring before service switching. S is the service bandwidth of the fault protection ring.

[0068] The above technical approach can promptly switch services on the faulty protection ring to the target protection ring, ensuring normal transmission of services carried on the faulty protection ring. It can also promptly update the remaining service bandwidth of the target protection ring, improving the reliability of transmission link fault handling.

[0069] FIG7 shows another flow diagram of a method for handling a transmission link failure according to an embodiment of the present application. As shown in FIG7 , step 104 may further include the following steps: before step S1041, step S1043 may be included to change the service state of the target protection ring to the operation state. After step S1042, step S1044 may be included to change the service state of the target protection ring to the activation state.

[0070] In some embodiments, after updating the remaining service bandwidth of the target protection ring according to the service bandwidth of the faulty protection ring and modifying the service state of the target protection ring to the activated state, a consistency check can be performed to determine the consistency of the service state of the target protection ring on the network element device and the network management device connected to the network element device.

[0071] In some embodiments, the service on the faulty protection ring is deleted, and the service is re-created on the target protection ring. Creation information in the target protection ring, such as creation time and creation user, may also be updated.

[0072] In some embodiments, when switching services on the faulty protection ring to the target protection ring, the service state of the faulty protection ring may also be modified to the operation state, and after the service switching is completed, the service state is updated to the fault state.

[0073] By adopting the above technical method, the services on the fault protection ring can be switched to the target protection ring in time to ensure the normal transmission of the services carried on the fault protection ring. It can also avoid conflicts in transmission link fault handling by modifying the service status (for example, multiple fault protection rings switch services to the same target protection ring), further improving the reliability of transmission link fault handling.

[0074] Figure 8 shows another flow chart of the method for handling transmission failures provided in an embodiment of the present application. As shown in Figure 8, the method may further include the following steps: in step S105, in response to the transmission link returning to normal, the service is switched from the target protection ring back to the fault protection ring that has returned to normal.

[0075] In some embodiments, services may be switched from the target protection ring back to the restored fault protection ring in the following manner.

[0076] Mode 1: In response to the return operation, the service is switched from the target protection ring back to the normal fault protection ring.

[0077] Mode 2: When the time after the faulty protection ring returns to normal is greater than or equal to a preset waiting time threshold for recovery, the service is switched from the target protection ring back to the faulty protection ring that has returned to normal.

[0078] The steps of switching the service from the target protection ring back to the restored fault protection ring are similar to steps S1041-S1042 and will not be described in detail. After switching the service back to the restored fault protection ring, the remaining service bandwidth of the target protection ring can be restored according to the service switching situation.

[0079] When there are frequent failures in the fault protection ring, service return can be controlled according to preset penalty parameters to avoid the impact of frequent service switching on service experience.

[0080] The above technical approach enables services to be switched to the target protection ring at the same virtual level, ensuring the normal transmission of services carried on the faulty protection ring. This also prevents failures on some logical transmission links from triggering service switching on the entire physical transmission link, preventing service switching from impacting services carried on other logical protection rings. This reduces transmission resource waste and improves transmission resource utilization. After the transmission link recovers, services can be promptly switched back to the restored faulty protection ring, further improving system maintainability.

[0081] Figure 9 shows a flow chart of a method for handling loop failures provided in an embodiment of the present application. As shown in Figure 9, the method may include the following steps: in step S201, in response to transmission link failure information in the first loop, the transmission link is fault-handled.

[0082] The fault information includes fault protection ring information.

[0083] In some embodiments, the method for handling transmission link failures shown in the embodiment of the first aspect of the present application can be used to handle transmission link failures. Taking Figure 2 as an example, the first loop can be a fiber protection ring L1. If any transmission link in the first loop (e.g., L1-3) fails, the method for handling transmission link failures shown in the embodiment of the first aspect of the present application can be used to handle the transmission link failure. The first target virtual level corresponding to the faulty protection ring is determined based on the fault information, and a first candidate protection ring that meets the preset conditions is determined from the protection rings whose virtual levels are the first target virtual levels included in the first loop.

[0084] Figure 10 shows another flow chart of the method for handling loop failures provided in an embodiment of the present application. As shown in Figure 10, the method may further include the following steps: in step S202, if a first candidate protection ring that meets the preset conditions is not determined in the protection ring of the first target virtual layer corresponding to the faulty protection ring, the service on the faulty protection ring in the first ring is switched to the second ring.

[0085] The second loop is a protection loop of the first loop, and the preset condition includes a preset state condition and / or a preset capacity condition.

[0086] If no first candidate protection ring meeting preset conditions is determined in the protection rings of the first target virtual level corresponding to the faulty protection ring, services on the faulty protection ring in the first ring may be switched to the second ring (eg, optical fiber protection ring L2).

[0087] Transmission link failures can be failures corresponding to protection rings at different virtual levels, and the causes of the failures can be varied. When the logical protection ring connection at the virtual level is interrupted, or the bit error rate of the logical protection ring connection at any virtual level exceeds a preset threshold, only the services on the faulty protection ring can be switched from the first ring to the second ring. In the event that the fault information indicates a serious and large-scale failure in the transmission link, such as a physical fiber break (i.e., a logical transmission protection ring connection at all virtual levels is interrupted), all services can also be switched from the first ring to the second ring.

[0088] By adopting the above-mentioned technical method, when there is no first candidate protection ring that meets the preset conditions in the protection ring of the first target virtual layer corresponding to the fault protection ring in the same loop, the service carried on the fault protection ring in the first loop can be switched to the second loop, thereby realizing cross-loop switching of the service carried on the logical protection ring of the first target virtual layer. This can avoid triggering service switching of the entire protection ring when the transmission link of some virtual layers fails, avoid affecting the services carried on the protection rings of other virtual layers due to switching, reduce the waste of transmission resources, and improve the utilization rate of transmission resources.
