In the current related technologies, for the recovery of network failures, protection routes are generally configured for network services. However, the reserved network bandwidth of the protection route is the same as the network bandwidth when the network service is normally transmitted.

When the first type of network service fails and the target network bandwidth required by the first type of network service is greater than the initial bandwidth, the initial bandwidth is adjusted to meet the service recovery function of the protection path, thereby improving the efficiency of network service fault recovery and reducing the waste of network bandwidth.

[0031] As described in the background technology section, in the current related technology, for the recovery of network failures, a protection route is generally configured for network services. However, the reserved network bandwidth of the protection route is the same as the network bandwidth during normal transmission of network services. Since network service failures are somewhat accidental, the reserved network bandwidth of the protection route is not only inefficient in use, but also wastes network bandwidth resources and even occupies the transmission bandwidth of other services, resulting in a limited number of services that the network can accommodate.

[0032] In summary, in order to solve the above problems, the present application embodiment proposes a network service failure recovery method, including:

[0033] In response to determining that a first type of network service has failed, determining an initial bandwidth of a protection path corresponding to the first type of network service; wherein a protection path is provided corresponding to the first type of network service, and the protection path is used to provide a backup transmission path for the first type of network service; determining whether a target network bandwidth corresponding to the first type of network service is greater than the initial bandwidth; in response to determining that the target network bandwidth is greater than the initial bandwidth, adjusting the initial bandwidth so that the adjusted initial bandwidth is greater than or equal to the target network bandwidth; restoring the first type of network service based on the protection path after adjusting the initial bandwidth, so that when the first type of network service has not failed, the protection path only reserves a small amount of initial bandwidth, and when the first type of network service fails and the target network bandwidth required by the first type of network service is greater than the initial bandwidth, the initial bandwidth is adjusted to meet the service recovery function of the protection path, thereby improving the efficiency of network service failure recovery and reducing the waste of network bandwidth.

[0039] The following describes the network service failure recovery method according to the exemplary implementation of the present application in conjunction with a specific application scenario. It should be noted that the above application scenario is only shown to facilitate understanding of the spirit and principle of the present application, and the implementation of the present application is not limited in this regard. On the contrary, the implementation of the present application can be applied to any applicable scenario.

[0040] refer to Figure 2 , is a flow chart of a network service failure recovery method according to an embodiment of the present application, the method comprising the following steps:

[0041] S101, in response to determining that a first type of network service has failed, determining an initial bandwidth of a protection path corresponding to the first type of network service; wherein a protection path is provided corresponding to the first type of network service, and the protection path is used to provide a backup transmission path for the first type of network service.

[0042] During the specific implementation, with the continuous development of technologies such as cloud-network integration and large-model computing, many emerging services have emerged, but different types of services often have different requirements for optical networks: such as data backup between data centers, due to the large amount of data, often requires large bandwidth transmission, but its real-time requirements for the network are relatively low; and voice, video conferencing and other services, in contrast, have lower bandwidth requirements, but require extremely low latency to ensure service quality. The first category of network services in the embodiments of the present application mainly refers to network services with higher priority, that is, network services with higher latency requirements, such as video conferencing. Optionally, the specific first category of network services can be set as needed without limitation. It should be noted that, considering that the first category of network services have higher latency requirements, therefore, in the embodiments of the present application, a backup protection path is set for the first category of network services. When the first category of network services fails, rapid fault recovery can be achieved through the protection path.

[0043] S102: Determine whether the target network bandwidth corresponding to the first type of network service is greater than the initial bandwidth.

[0044] In the specific implementation, considering that the occurrence of network failures is somewhat accidental, in order to avoid wasting network resources, an initial bandwidth can be set for the protection path, and the initial bandwidth is generally relatively small. For example, the initial bandwidth can be set to 2M through OSU (Optical Service Unit) technology. In this way, every time a first-class network service fails, it is first determined whether the target network bandwidth corresponding to the first-class network service is greater than the initial bandwidth. If it is less, the first-class network service can be directly restored through the protection path. If it is greater, the initial bandwidth at this time cannot meet the network failure recovery requirements, and it is necessary to further perform step S103.

[0045] S103: In response to determining that the target network bandwidth is greater than the initial bandwidth, adjust the initial bandwidth so that the adjusted initial bandwidth is greater than or equal to the target network bandwidth.

[0046] In specific implementation, when it is determined that the target network bandwidth is greater than the initial bandwidth, in order to meet the bandwidth requirements of network fault recovery, the initial bandwidth can be adjusted first so that the adjusted initial bandwidth is greater than or equal to the target network bandwidth. It should be noted that in some embodiments, no matter how the initial bandwidth is adjusted, it may not meet the network requirements for fault recovery, that is, the adjusted initial bandwidth is less than the target network bandwidth. At this time, a network fault prompt message can be directly issued, that is, the network fault recovery fails.

[0047] S104: Restore the first type of network service based on the protection path after adjusting the initial bandwidth.

[0048] In specific implementation, after adjusting the initial bandwidth, the first type of network service can be restored according to the protection path after adjusting the initial bandwidth, that is, the protection path after adjusting the network bandwidth can replace the original path of the first type of network service to transmit information.

[0049] In some embodiments, adjusting the initial bandwidth specifically includes:

[0050] Determining a remaining adjustable bandwidth corresponding to the protection path;

[0051] Determining whether the remaining adjustable bandwidth is greater than or equal to the target network bandwidth;

[0052] In response to determining that the remaining adjustable bandwidth is less than the target network bandwidth, determining at least one second type of network service corresponding to the protection path; wherein the priority of the second type of network service is less than the priority of the first type of network service;

[0053] reducing the network bandwidth of the at least one second type of network service to increase the remaining adjustable bandwidth;

[0054] The initial bandwidth is adjusted based on the increased remaining adjustable bandwidth.

[0055] In specific implementation, since the protection path normally only reserves the initial bandwidth, when adjusting the initial bandwidth, it may be affected by the network bandwidth of other services carried by the protection path, that is, it is necessary to first determine the remaining adjustable bandwidth corresponding to the protection path, which is the currently idle and available network bandwidth of the protection path in addition to the initial bandwidth. When it is determined that the remaining adjustable bandwidth is less than the target network bandwidth, that is, the remaining adjustable bandwidth cannot meet the adjustment requirements, in this embodiment, the network bandwidth of the second type of network service currently using the protection path can be further reduced, so that the remaining adjustable bandwidth can be increased. Optionally, the priority of the second type of network service is less than the priority of the first type of network service, that is, the second type of network service is generally a low-priority network service, such as data backup in the above embodiment. It should be noted that the at least one second type of network service corresponding to the protection path can be multiple or one. When the at least one second type of network service is multiple, the remaining adjustable bandwidth can be increased by reducing the network bandwidth of multiple second type network services.

[0056] In some embodiments, reducing the network bandwidth of the at least one second type of network service specifically includes:

[0057] Determine a first target network service having the largest network bandwidth from the at least one second type of network service;

[0058] The network bandwidth of the first target network service is reduced based on a preset maximum delay tolerance.

[0059] In specific implementation, when there are multiple second-class network services, the first target network service with the largest network bandwidth can be reduced first, so that only one second-class network service may be reduced to meet the fault recovery requirements, thereby minimizing the impact on other second-class network services.

[0060] In some embodiments, reducing the network bandwidth of the first target network service based on a preset maximum delay tolerance specifically includes:

[0061] Acquire the original network bandwidth of the first target network service;

[0062] Determine a maximum reducible bandwidth corresponding to the first target network service based on the preset maximum delay tolerance and the original network bandwidth;

[0063] In response to determining that the maximum reducible bandwidth is less than the difference between the target network bandwidth and the initial bandwidth, determining a second target network service having the largest network bandwidth from the at least one second type of network service other than the first target network service;

[0064] The network bandwidth of the first target network service and the network bandwidth of the second target network service are reduced at the same time.

[0065] In specific implementation, when only reducing the network bandwidth of the first target network service cannot meet the demand, a second target network service with the largest network bandwidth can be further determined among the at least one second-class network service other than the first target network service, and the network bandwidth of the first target network service and the network bandwidth of the second target network service can be reduced at the same time. It should be noted that, taking this implementation as an example, when it is necessary to reduce the network bandwidth of multiple second-class network services, the network bandwidth of each second-class network service can be reduced in order from large to small network bandwidth until the demand for network fault recovery is met.

[0066] In some embodiments, the method further comprises:

[0067] In response to determining that a second type of network service has failed, reconstructing a route for the second type of network service in a network system corresponding to the second type of network service; wherein the priority of the second type of network service is lower than the priority of the first type of network service, and the network system includes a plurality of network nodes; the plurality of network nodes include a source node and a sink node corresponding to the second type of network service;

[0068] The second type of network service is restored by the reconstructed routing.

[0069] In the specific implementation, considering that the second type of network service has a lower requirement for network delay, therefore, in the embodiment of the present application, when the second type of network service fails, the failure recovery is not performed through a specially set protection path, but the route is reconstructed for the second type of network service in the network system corresponding to the second type of network service. Optionally, the network system corresponding to the second type of network service can be a network system between multiple network nodes established based on an optical transport network (OTN).

[0070] In some embodiments, the second type of network service is multiple; and reconstructing a route for the second type of network service in a network system corresponding to the second type of network service specifically includes:

[0071] Obtaining service duration and service bandwidth corresponding to each of the second-category network services;

[0072] Prioritizing recovery of each of the second-category network services based on the service duration and service bandwidth;

[0073] Based on the result of the priority restoration sorting, the route is reconstructed for each of the second-category network services in turn.

[0074] In specific implementation, in some embodiments, the priority recovery sorting can be performed using the following formula:

[0075]

[0076] o i The recovery order value of the business, optional, o i The larger the value of , the higher the priority recovery ranking. α and β are weight parameters, α+β=1, t i is the duration of the ith service (the total number of services is n), b i is the required bandwidth of the ith service, b j is the remaining bandwidth of the jth link of the current route (total number of link segments m), b is the average remaining bandwidth of the link segments of the current route, and services with large recovery order values ​​are restored first. Among them, the first term (α·(1 / t i )) means that the services with short duration are restored first, so more services can be restored within the specified time. The second Indicates that the services with balanced remaining bandwidth of the link are restored first. Optionally, in some embodiments, other methods can be used to prioritize the restoration of each of the second-category network services according to the service duration and service bandwidth. For example, priority can be given to restoring services with short duration, or priority can be given to restoring services with balanced remaining bandwidth of the link, without limitation.

[0077] In some embodiments, reconstructing a route for the second type of network service in a network system corresponding to the second type of network service specifically includes:

[0078] In response to determining that the second type of network service corresponds to multiple alternative routes, obtaining a load balancing value of each of the alternative routes; wherein the load balancing value is a mean square error between the remaining resources of each link of the alternative route and the average remaining resources of all links;

[0079] Determine a target candidate route with the smallest load balancing value from the multiple candidate routes; and reconstruct a route for the second type of network service based on the target candidate route.

[0080] In specific implementation, load balancing refers to the mean square error of the remaining resources of each link segment in each alternative route and the average remaining resources of multiple (all) links of the alternative route. The smaller the mean square error, the better the network load balancing degree. In the embodiment of the present application, when there are multiple alternative routes corresponding to the second type of network service, priority is given to matching the target alternative route with better load balancing degree.

[0081] The network service fault recovery method provided by the present application determines, in response to determining that a first type of network service has failed, an initial bandwidth of a protection path corresponding to the first type of network service; wherein a protection path is set corresponding to the first type of network service, and the protection path is used to provide a backup transmission path for the first type of network service; determines whether a target network bandwidth corresponding to the first type of network service is greater than the initial bandwidth; in response to determining that the target network bandwidth is greater than the initial bandwidth, adjusts the initial bandwidth so that the adjusted initial bandwidth is greater than or equal to the target network bandwidth; restores the first type of network service based on the protection path after adjusting the initial bandwidth, so that when the first type of network service has not failed, the protection path only reserves a small amount of initial bandwidth, and when the first type of network service fails and the target network bandwidth required by the first type of network service is greater than the initial bandwidth, the initial bandwidth is adjusted to meet the service recovery function of the protection path, thereby improving the efficiency of network service fault recovery and reducing the waste of network bandwidth.

[0082] Based on the same inventive concept, corresponding to any of the above-mentioned embodiment methods, the present application also provides a network service failure recovery device.
