[0002] In an IGP (Interior Gateway Protocol) network, adding a new route or device requires configuring metrics (a numerical value used in routing protocols to measure link quality).

[0050] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0051] The metric value determination method provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown. The target device 102 communicates with the server 104 through the network. The data storage system can store the data that the server 104 needs to process. The data storage system can be integrated on the server 104, or it can be placed on the cloud or other network servers. By obtaining the first role information of the adjacent device, the connected link attributes are determined according to the first role information and the second role information of the target device, and then the reference metric value corresponding to the connected link attribute is used as the target metric value of the corresponding interface between the target device and the adjacent device. The terminal 102 can be, but is not limited to, various personal computers, laptops, smart phones, tablets, Internet of Things devices and portable wearable devices. The Internet of Things devices can be smart speakers, smart TVs, smart air conditioners, smart car-mounted devices, etc. Portable wearable devices can be smart watches, smart bracelets, head-mounted devices, etc. The server 104 can be implemented as an independent server or a server cluster consisting of multiple servers.

[0052] In one embodiment, Figure 2 As shown, a metric value determination method is provided, which is applied to Figure 1 Taking the target device in as an example, the following steps are included:

[0053] S201: Acquire first role information of a neighboring device.

[0054] It should be noted that the first role information refers to the ROLE information corresponding to the adjacent device; specifically, when the first role information of the adjacent device needs to be obtained, a greeting message of the adjacent device can be received, and the first role information of the adjacent device can be obtained from the greeting message.

[0055] In one embodiment of the present application, after the target device accesses the network, ISIS neighbor negotiation may be triggered; further, during the ISIS neighbor negotiation process, a hello message from a neighboring device is received, and the first role information of the neighboring device is obtained from the hello message.

[0056] S202: Determine a connected link attribute according to the first role information and the second role information of the target device.

[0057] It should be noted that the second role information of the target device can be configured after the target device is connected to the network in combination with the pre-settings of the operation and maintenance personnel; the role information may include but is not limited to: core, aggregation, access, etc.

[0058] Specifically, after the target device is connected to the network, the device role is defined in combination with the pre-set settings of the operation and maintenance personnel and written into the newly defined ROLE TLV, which is encapsulated in the hello message. Among them, the ROLE TLV contains a one-byte role code (RoleCode), which is the second role information of the target device. An example is shown below:

[0059] Type:256(0x0100)

[0060] Length:2

[0061] Value: [Role Code (1 byte) Priority (1 byte)]

[0062] It is further explained that when it is necessary to determine the attributes of the connected link based on the first role information and the second role information of the target device, all possible candidate link attributes can be obtained in advance, and then the correspondence between the target device and the adjacent device and each candidate link attribute can be judged based on the first role information and the second role information of the target device. If the target device and the adjacent device correspond to a candidate link attribute, the candidate link attribute is used as the connected link attribute.

[0063] Specifically, each candidate link attribute is a link attribute connecting two devices. If the role information of the target device and the adjacent device of the two devices connected by a candidate link attribute are the same, then it is considered that the target device and the adjacent device correspond to each other.

[0064] S203: Using the reference metric value corresponding to the connected link attribute as the target metric value of the corresponding interface between the target device and the adjacent device.

[0065] In one embodiment of the present application, a correspondence between at least one candidate link attribute and at least one candidate metric value can be obtained in advance; the correspondence records different candidate metric values ​​corresponding to different candidate link attributes, and then, based on the correspondence, a reference metric value corresponding to the connected link attribute is determined; and the reference metric value corresponding to the connected link attribute is used as the target metric value of the corresponding interface between the target device and the adjacent device.

[0066] The above-mentioned metric value determination method obtains the first role information of the adjacent device, and determines the attributes of the connected link according to the first role information and the second role information of the target device, and then uses the reference metric value corresponding to the attributes of the connected link as the target metric value of the interface corresponding to the target device and the adjacent device. According to the above content, when the metric value needs to be obtained, the present application will pre-acquire the first role information of the adjacent device and the second role information of the target device, and then, according to the first role information and the second role information, determine the attributes of the connected link corresponding to the target device and the adjacent device, and determine the final target metric value through the attributes of the connected link, thereby ensuring that the determination of the target metric value is associated with the attributes of the connected link corresponding to the target device and the adjacent device, and further ensuring the accuracy of the determination of the target metric value. Compared with the method of manually determining the metric value in the prior art, the present application can not only effectively improve the efficiency of determining the target metric value, but also ensure the accuracy of determining the target metric value, and prevent the occurrence of traffic flow confusion, network congestion and even packet loss due to the deviation in the determination of the target metric value.

[0067] In one embodiment, if Figure 3 As shown, when it is necessary to determine the attributes of the connected link based on the first role information and the second role information of the target device, the following may be specifically included:

[0068] S301: Determine a first role attribute of a neighboring device according to first role information.

[0069] In an embodiment of the present application, when it is necessary to determine the first role attribute of the neighboring device according to the first role information, the following may be included: parsing the first role information to obtain the first role attribute of the neighboring device.

[0070] As an example, the first role information may include a first attribute identifier corresponding to the first role attribute; when it is necessary to determine the first role attribute of the adjacent device, the first attribute identifier contained in the first role information may be extracted, and then, based on the role attribute corresponding to the first attribute identifier, the first role attribute of the adjacent device may be determined.

[0071] S302: Determine a second role attribute of the target device according to the second role information of the target device.

[0072] In another embodiment of the present application, when it is necessary to determine the second role attribute of the target device according to the second role information of the target device, the following may be included: parsing the second role information of the target device to obtain the second role attribute of the target device.

[0073] As an example, the second role information may include a second attribute identifier corresponding to the second role attribute; when it is necessary to determine the second role attribute of the adjacent device, the second attribute identifier contained in the second role information may be extracted, and then, based on the role attribute corresponding to the second attribute identifier, the second role attribute of the target device may be determined.

[0074] S303: Determine the attributes of the connected link according to the first role attributes and the second role attributes.

[0075] In one embodiment of the present application, when it is necessary to determine the connected link attribute based on the first role attribute and the second role attribute, the following contents may be included: obtaining at least one candidate link attribute included in the Metric configuration policy; wherein each candidate link attribute corresponds to two candidate role attributes; and taking the candidate link attributes corresponding to the first role attribute and the second role attribute, respectively, of the two candidate role attributes as the connected link attributes.

[0076] The above-mentioned metric value determination method, by obtaining the first role attribute of the adjacent device and the second role attribute of the target device, realizes the determination of the connected link attribute based on the first role attribute and the second role attribute, and provides a data basis for the subsequent determination of the target metric value of the corresponding interface between the target device and the adjacent device. It ensures that the first role attribute of the adjacent device and the second role attribute of the target device can be combined when determining the target metric value, thereby improving the accuracy of the subsequent determination of the target metric value.

[0077] In one embodiment, if Figure 4 As shown in the figure, when determining the reference metric value corresponding to the connected link attribute, the following contents may also be included:

[0078] S401: Obtain the mapping relationship included in the Metric configuration policy.

[0079] The mapping relationship records different candidate metric values ​​corresponding to different candidate attribute links.

[0080] It should be noted that the mapping relationship can be set or adjusted according to the historical experience and actual situation of the operation and maintenance personnel, and the specific content of the mapping relationship is not limited here.

[0081] As an example, the relationship table corresponding to the mapping relationship can be shown as follows:

[0082]

[0083] S402: Determine a reference metric value corresponding to the connected link attribute according to the mapping relationship.

[0084] It should be noted that when it is necessary to determine the reference metric value corresponding to the connected link attribute based on the mapping relationship, the following may be included: selecting a reference attribute link with the same attribute as the connected link from the candidate attribute links contained in the mapping relationship; and using the candidate metric value corresponding to the reference attribute link in the mapping relationship as the reference metric value corresponding to the connected link attribute.

[0085] In one embodiment of the present application, Figure 5 As shown, if there are five adjacent devices in total, the five adjacent devices are adjacent device A, adjacent device B, adjacent device C, adjacent device D and adjacent device E; if the second role attribute of the target device is core, the first role attribute of adjacent device A is core, the first role attribute of adjacent device B is core, the first role attribute of adjacent device C is aggregation, the first role attribute of adjacent device D is aggregation and the first role attribute of adjacent device E is access; therefore, the relationship table corresponding to the mapping relationship is as shown in the above table, therefore, it can be determined that the link attribute between the target device and the adjacent device A is between cores, therefore, the target metric value of the corresponding interface between the target device and the adjacent device A is 6000; it can also be determined that the target device The link attribute between the target device and neighboring device B is core-to-core. Therefore, the target metric value of the corresponding interface between the target device and neighboring device B is 6000. The link attribute between the target device and neighboring device C is core-aggregation. Therefore, the target metric value of the corresponding interface between the target device and neighboring device C is 12000. The link attribute between the target device and neighboring device D is core-aggregation. Therefore, the target metric value of the corresponding interface between the target device and neighboring device D is 12000. The link attribute between the target device and neighboring device E is core-access. Therefore, the target metric value of the corresponding interface between the target device and neighboring device D is 30000.

[0086] The above-mentioned metric value determination method obtains the mapping relationship contained in the metric configuration policy and determines the reference metric value corresponding to the connected link attribute based on the mapping relationship. This provides a data judgment basis for subsequently determining the target metric value of the corresponding interface between the target device and the adjacent device, ensuring the accuracy of the target metric value.

[0087] In one embodiment, if Figure 6 As shown in the figure, when you need to determine the target metric value of the corresponding interface of the target device and the adjacent device, you can include the following:

[0088] S601: Acquire first role information of a neighboring device.

[0089] S602: Determine a first role attribute of a neighboring device according to the first role information.

[0090] S603: Determine a second role attribute of the target device according to the second role information of the target device.

[0091] S604: Obtain at least one candidate link attribute included in the metric configuration policy; wherein each candidate link attribute corresponds to two candidate role attributes.

[0092] S605: Take the two candidate role attributes corresponding to the first role attribute and the second role attribute respectively as the candidate link attributes.

[0093] S606: Obtain a mapping relationship included in the metric configuration policy, wherein the mapping relationship records different candidate metric values ​​corresponding to different candidate attribute links.

[0094] S607: Select a reference attribute link having the same attribute as the connected link from each candidate attribute link included in the mapping relationship.

[0095] S608: Use the candidate metric value corresponding to the reference attribute link in the mapping relationship as the reference metric value corresponding to the connected link attribute.

[0096] S609: Use the reference metric value corresponding to the connected link attribute as the target metric value of the interface corresponding to the target device and the adjacent device.

[0097] The above-mentioned metric value determination method obtains the first role information of the adjacent device, and determines the attributes of the connected link according to the first role information and the second role information of the target device, and then uses the reference metric value corresponding to the attributes of the connected link as the target metric value of the interface corresponding to the target device and the adjacent device. According to the above content, when the metric value needs to be obtained, the present application will pre-acquire the first role information of the adjacent device and the second role information of the target device, and then, according to the first role information and the second role information, determine the attributes of the connected link corresponding to the target device and the adjacent device, and determine the final target metric value through the attributes of the connected link, thereby ensuring that the determination of the target metric value is associated with the attributes of the connected link corresponding to the target device and the adjacent device, and further ensuring the accuracy of the determination of the target metric value. Compared with the method of manually determining the metric value in the prior art, the present application can not only effectively improve the efficiency of determining the target metric value, but also ensure the accuracy of determining the target metric value, and prevent the occurrence of traffic flow confusion, network congestion and even packet loss due to the deviation in the determination of the target metric value.

Unless otherwise specified herein, there is no strict order restriction on the execution of these steps, and these steps can be performed in other orders. Moreover, at least a portion of the steps in the flowcharts of the above embodiments may include multiple steps or multiple stages, and these steps or stages are not necessarily performed at the same time, but can be performed at different times. The execution order of these steps or stages is not necessarily to be performed in sequence, but can be performed in turn or alternately with other steps or at least a portion of steps or stages in other steps.
