Description

Technical Field

[0001] Embodiments of the present disclosure relate to the technical field of transmission networks, and particularly to methods for resource allocation, network devices, electronic devices, and computer-readable media. Background Art

[0002] In a transmission network (such as an optical transmission network), compared with core layer and aggregation layer devices, the service types of access layer devices are more diverse. For different service types, the bandwidth requirements are also different, and the requirements for resources are also diverse. Some require continuous resources, while others can be discrete.

[0003] When an access layer device opens a service, an operator needs to manually configure service ports through an NMS (Network Management System) according to the accessed service type. For example, an FC1600 (Fibre Channel 1600) service needs to occupy 11 discontinuous resources, and the operator needs to manually check multiple resource numbers on the NMS interface.

[0053] Embodiments of this disclosure are not limited to the embodiments shown in the drawings, but include modifications to the configurations formed based on the manufacturing process. Therefore, the regions illustrated in the drawings have schematic properties, and the shapes of the regions shown in the figures illustrate the specific shapes of the regions of the elements, but are not intended to be restrictive.

[0054] In a first aspect, with reference to Figure 1 , embodiments of this disclosure provide a method for resource allocation.

[0055] The method of the embodiments of this disclosure is used for a network device to execute, and different network devices can be interconnected to form a network. Among them, each network device has one or more ports, and the corresponding ports of two interconnected network devices are connected. When the corresponding ports of two interconnected network devices access the same service and use the same resources, the corresponding service is enabled, and the two can achieve service information exchange.

[0056] Among them, in some embodiments, the network device can be an optical network device, and the network formed by interconnecting different network devices is an optical transmission network.

[0057] With the rapid development of 5G, the service access types of the access layer devices in the optical transmission network are becoming increasingly rich, such as SDH (Synchronous Digital Hierarchy), FC (Fibre Channel), CPRI (Common Public Radio Interface), OTN (Optical Transport Network), FICON (Fiber Connection), Ethernet, etc. Different service types require different resources, resulting in a complex configuration process and a high error rate for manual configuration.

[0058] However, the resource configuration method of this embodiment can automatically implement resource configuration and solve the problem of difficult resource configuration in the optical transmission network.

[0059] The resource configuration method of this embodiment specifically includes:

[0060] S101. Determine that the service of at least one port is updated to a service to be enabled, and the port whose service is updated to a service to be enabled is the port to be configured.

[0061] The identification module of the local device identifies that the access service of a certain port in the local device has changed (such as changing from no service access to having service access, or changing from one service to another service), and it is necessary to reconfigure resources for it. Then, determine the port whose service has changed as the port to be configured, and the service after the change is the service to be enabled.

[0062] S102. Obtain the service and resources of the peer port of the remote device connected to the port to be configured.

[0063] After the identification module of the local device determines that the port connected to the port to be configured in the remote device connected to the local device is the peer port, the acquisition module of the local device acquires the current service of the peer port and the resources it occupies.

[0064] S103. If the peer port has been configured, configure the same resources as the peer port for the port to be configured; if the peer port has not been configured, configure resources for the port to be configured at least according to the local idle resources, where the peer port has been configured means that the service of the peer port is the service to be enabled and the resources have been configured.

[0065] The configuration module of the local device determines whether the peer port has been configured (that is, the current service of the peer port is the service to be enabled, and the port has been configured with resources that meet the requirements of the service to be enabled).

[0066] If so, configure the same resources for the port to be configured according to the resource configuration of the peer port.

[0067] If it is determined that the peer port has not been configured (that is, the peer port has not been configured with resources or the current service of the peer port is not the service to be enabled), then configure resources for the port to be configured at least according to the local idle resources.

[0068] The completion of the service requires the port to be configured and the peer port to be configured with the same resources. Therefore, if the peer port has been configured, only configure the same resources for the port to be configured according to the resource configuration of the peer port. If the peer port has not been configured, then configure resources for the port to be configured at least according to the local idle resources. When the peer port needs to be configured with resources, configure the same resources as the port to be configured to complete the service.

[0069] The local device is a network device that executes the method of resource configuration, and the port where the access service changes is the port to be configured. The remote device refers to the network device connected to the local device, and the port connected to the port to be configured in the remote device is the peer port.

[0070] Therefore, for the same network device, different ports may have changes in access services at different times. Therefore, any port in the local device can become the port to be configured.

[0071] Since the condition for enabling the service is that both connected ports access the service and are configured with the same resources, the access service types of the two connected ports will change (but there may be a time difference in the change of the access service type). Therefore, the network devices where the two connected ports are located will both execute the method of resource configuration. Therefore, when these two network devices execute the method of resource configuration, they are both local devices and also the remote devices of each other.

[0072] At the same time, since the resource configuration of the two ports is usually not completely synchronized, but one is configured first and the other is configured later. Therefore, for the port configured first, when its network device executes the method of resource configuration, it will find that the corresponding remote port has not been configured, so configure the port to be configured at least according to the local idle resources; for the port configured later, when its network device executes the method of resource configuration, it will find that the corresponding remote port has been configured, so it can configure resources for it according to the resource configuration of the remote port.

[0073] Such as referring to Figure 6, there are two network devices, A and B. Each network device has n ports (numbered 1 to n) and can use 8 * n resources (numbered 1 to 8 * n). When a service needs to be established between network devices A and B, one port from each of A and B is required, and the same resources (i.e., resources with the same number) are configured for the ports. If the ports do not correspond or the configured resources are different, the service cannot be successfully established.

[0074] Generally speaking, the corresponding rule for ports of different network devices is that ports with the same number correspond to each other. The following also takes this as an example.

[0075] When the service type accessed by port 1 of A (for example) changes and resources need to be configured for it, port 1 of A is the port to be configured, and the corresponding port of B to port 1 of A is the peer port (i.e., port 1 of B).

[0076] Generally, when the service type accessed by port 1 of A (for example) changes, the corresponding port of B (i.e., port 1 of B) also needs to change (only the time may be different). When the service type accessed by port 1 of B (for example) changes and resources need to be configured for it, port 1 of B is the port to be configured, and the corresponding port of A to port 1 of B (i.e., port 1 of A) is the peer port.

[0077] Of course, the port correspondence relationship between A and B can be changed (such as modified through software configuration files, hardware DIP switches, network management configurations, etc.).

[0078] Then the process of this resource configuration method (taking the configuration of resources for port 1 of A as an example) can be specifically as follows:

[0079] Determine that port 1 of A is the port to be configured, and the service accessed by port 1 (such as a service that requires 7 non - consecutive resources) is the service to be updated.

[0080] Obtain the resource configuration and the accessed service of port 1 of B corresponding to port 1 of A.

[0081] If the configuration of port 1 of B has been completed, that is, the service accessed by port 1 of B is the service to be updated and resources have been configured, then only the corresponding - numbered resources need to be configured for port 1 of A.

[0082] If the configuration of port 1 of B has not been completed, then at least configure resources for port 1 of A according to the local idle resources (i.e., resources not configured for any port of A). When configuring resources for port 1 of B, the same resources can be configured for port 1 of B according to the configuration that port 1 of A has completed. It should be emphasized that during the process of configuring resources for port 1 of B, port 1 of B is the port to be configured in this process, while port 1 of A becomes the peer port.

[0083] The resource configuration method provided by the embodiment of the present disclosure automatically configures the local port according to the services and resources of the opposite port of the remote device, thereby solving the problems of low efficiency and cumbersome operation of manual configuration and improving the efficiency of resource configuration.

[0084] In some embodiments, reference Figure 2 , determining that the service of at least one port is updated as the service to be opened (S101) and obtaining the service and resources of the opposite port of the remote device connected to the port to be configured (S102) also includes: S201, if the port to be configured has been configured with resources, releasing the configured resources.

[0085] After the identification module determines the port to be configured, the configuration module first determines whether the port to be configured has been configured with resources before. If resources have been configured, the currently configured resources cannot meet the requirements of the service to be updated due to the change in the access service type. Therefore, it is necessary to release the configured resources and reconfigure the resources for the port to be configured.

[0086] Before reconfiguring resources for the port to be configured, the resources previously configured for the port to be configured are released, so that the number of idle resources can be increased, that is, the number of resources that can be configured for the port to be configured is increased, which is useful for configuring more appropriate resources for the port to be configured.

[0087] In some embodiments, reference Figure 3 , configuring resources for the port to be configured at least according to the local idle resources (S103) includes:

[0088] S301: If resources are not configured for the opposite port, configure resources for the port to be configured according to local idle resources and remote idle resources, wherein the remote idle resources are idle resources of a remote device.

[0089] S302: If resources have been configured for the opposite port and the service of the opposite port is not a service to be opened, resources are configured for the port to be configured from local idle resources according to a predetermined rule.

[0090] When the configuration module determines that the peer port has not completed configuration (ie, the peer port has no resources configured or the current service of the peer port is not a service to be opened), the configuration module needs to further determine whether the peer port has no resources configured or has resources configured but the current service is not a service to be opened.

[0091] If the opposite port is not configured with resources, the configuration module configures resources for the port to be configured according to the acquired local idle resources and remote idle resources.

[0092] The remote idle resources are idle resources of the remote device, that is, resources that are not configured to any port of the remote device.

[0093] The acquisition module of the local device can acquire the services and resources of the peer port of the remote device connected to the port to be configured (S102) while acquiring the remote free resources of the remote device (or acquiring the usage of all resources of the remote device); of course, the acquisition module can also acquire the remote free resources of the remote device and send them to the configuration module after the configuration module determines that the peer port has no configured resources for the configuration module to configure resources for the port to be configured according to the local free resources and the remote free resources.

[0094] When the peer port has no configured resources, resources are configured for the port to be configured according to the local free resources and the remote free resources. The resources configured by the port to be configured are within the remote free resources. Therefore, when configuring resources for the peer port according to the resources configured by the port to be configured, the situation where the resources to be configured are occupied will not occur, improving the configuration efficiency.

[0095] If the peer port has configured resources, but the accessed service is not the service to be updated, resources are configured for the port to be configured from the local free resources according to a predetermined rule.

[0096] When the peer port has already configured resources, but the accessed service is not the service to be updated, when the peer port accesses the service to be updated and needs to reconfigure resources for it, the currently occupied resources need to be released. After the release, the number of remote free resources is greater than the current number of remote free resources. Therefore, only the local free resources need to be used to configure resources for the port to be configured. This increases the number of resources available for configuration and is conducive to configuring more suitable resources for the port to be configured.

[0097] In some embodiments, referring to Figure 4 , configuring resources for the port to be configured according to the local free resources and the remote free resources (S301) includes:

[0098] S401. If the number of resources in both the local free resources and the remote free resources is not less than the number of resources required for the service to be enabled, resources are configured for the port to be configured from the resources in both the local free resources and the remote free resources according to a predetermined rule.

[0099] After the acquisition module acquires the local free resources and the remote free resources, the configuration module determines whether the resources in both the local free resources and the remote free resources (that is, the resources that are not allocated to any port of the local device and not allocated to any port of the remote device) meet the requirements of the service to be enabled (such as whether the quantity is sufficient). If sufficient, resources are configured for the port to be configured from the resources in both the local free resources and the remote free resources according to a predetermined rule.

[0100] Configure resources for the port to be configured from the resources that are both local idle resources and remote idle resources. The resources configured for the port to be configured are in the remote idle resources. Therefore, when configuring resources for the peer port according to the resources configured for the port to be configured, the situation where the resources to be configured are occupied will not occur, improving the configuration efficiency.

[0101] For example, configure resources for port 1 of A, and port 1 of B is the peer port of port 1 of A.

[0102] When port 1 of B is not configured with resources, obtain the resources that are both in the idle resources of A (resources not configured for any port of A) and in the idle resources of B (resources not configured for any port of B). For example, if the idle resource numbers of A are 1, 2, 3, 4 and the idle resource numbers of B are 2, 3, 4, 5, then the resources that are both in the idle resources of A and in the idle resources of B are 2, 3, 4.

[0103] If the service to be activated requires 2 consecutive resources, the resources that are both in the idle resources of A and in the idle resources of B meet the requirements of the service to be activated. Just configure resources for the port to be configured from the resources that are both in the idle resources of A and in the idle resources of B, such as 2 and 3.

[0104] In some embodiments, referring to Figure 4 , configuring resources for the port to be configured according to the local idle resources and the remote idle resources (S301) includes:

[0105] S402. If the number of resources that are both in the local idle resources and in the remote idle resources is less than the number of resources required for the service to be activated, then configure resources for the port to be configured from the local idle resources according to a predetermined rule.

[0106] After the acquisition module acquires the local idle resources and the remote idle resources, the configuration module determines whether the resources that are both in the local idle resources and in the remote idle resources (that is, the resources not allocated to any port of the local device and not allocated to any port of the remote device) meet the requirements of the service to be activated (such as whether the quantity is sufficient). If not, then configure resources for the port to be configured from the local idle resources according to a predetermined rule.

[0107] For example, configure resources for port 1 of A, and port 1 of B is the peer port of port 1 of A.

[0108] When port 1 of B is not configured with resources, obtain the resources that are both in the idle resources of A (resources not configured for any port of A) and in the idle resources of B (resources not configured for any port of B). For example, if the idle resource numbers of A are 1, 2, 3, 4 and the idle resource numbers of B are 2, 3, 4, 5, then the resources that are both in the idle resources of A and in the idle resources of B are 2, 3, 4.

[0109] If the service to be activated requires 4 consecutive resources, the resources that are both in the idle resources of A and in the idle resources of B do not meet the requirements of the service to be activated. Resources can be configured for the port to be configured from the idle resources of A, such as 1, 2, 3, 4.

[0110] In some embodiments, referring to Figure 5 , configuring resources for the port to be configured from the local idle resources according to a predetermined rule includes:

[0111] S501. If the number of resources in the local idle resources is not less than the number of resources required for the service to be activated, configure resources for the port to be configured from the local idle resources in sequence.

[0112] The configuration module determines whether the resources that are both in the local idle resources (i.e., the resources that are not allocated to any port of the local device and not allocated to any port of the remote device) meet the requirements of the service to be activated (such as whether the quantity is sufficient). If sufficient, configure resources for the port to be configured from the local idle resources in sequence.

[0113] For example, when configuring resources for port 1 of A, the idle resources of A (the resources not configured for any port of A) are numbered 1, 2, 3, 4. If the service to be activated requires 2 consecutive resources, then configure resources for the port to be configured from the local idle resources in sequence, that is, the resources numbered 1 and 2.

[0114] S502. If the number of resources in the local idle resources is less than the number of resources required for the service to be activated, return to the step of determining that the services of at least one port are updated to services to be activated.

[0115] The configuration module determines whether the resources that are both in the local idle resources (i.e., the resources that are not allocated to any port of the local device and not allocated to any port of the remote device) meet the requirements of the service to be activated (such as whether the quantity is sufficient). If not enough, return to the step of determining that the services of at least one port are updated to services to be activated.

[0116] For example, when configuring resources for port 1 of A, the idle resources of A (the resources not configured for any port of A) are numbered 1, 2, 3, 4. If the service to be activated requires 5 consecutive resources, the idle resources of A do not meet the requirements, the configuration fails, and return to the step of obtaining the services and resources of the peer port of the remote device connected to the port to be configured.

[0117] In a second aspect, referring to Figure 7 , an embodiment of the present disclosure provides a network device for resource configuration, which includes:

[0118] At least one port, and the port is connected to the port of the remote device;

[0121] A configuration module, configured to, when the peer port has been configured, configure the same resources for the port to be configured as those of the peer port, and when the peer port has not been configured, configure resources for the port to be configured at least according to local idle resources;

[0122] Wherein,

[0123] That the peer port has been configured means that the service of the peer port is a service to be activated and the resources have been configured.
