In the channelized sub-interface slicing technology, users can slice multiple channelized sub-interface links from a single link. However, service traffic changes at any time. If the slice bandwidth is too small, the service cannot be guaranteed, which will cause service congestion and packet loss. If the slice bandwidth is too large, the bandwidth utilization rate will decrease, resulting in bandwidth waste. Summary of the invention

[0044] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, rather than limiting the present application. The singular forms of "a", "said" and "the" used in the present application and claims are also intended to include plural forms, unless the context clearly indicates other meanings. It should also be understood that the term "and / or" used herein refers to any or all possible combinations of one or more associated listed items.

[0045] It should be understood that, although the terms first, second, third, etc. may be used to describe various information in the embodiments of the present application, these information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present application, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Depending on the context, in addition, the word "if" used may be interpreted as "at..." or "when..." or "in response to determination".

[0046] For example, see Figure 1 FIG. 1 is a detailed flow chart of a slice bandwidth adjustment method provided in an embodiment of the present application, and the method includes the following steps:

[0047] Step 100: Collect current real-time bandwidth information of the target slice.

[0048] In actual applications, when a slice service (such as a target service) is deployed, an initial maximum available bandwidth (such as 100M) is set for the slice (such as a target slice), and the slice is used to carry the traffic of the service. At this time, the controller can monitor the real-time bandwidth of the slice. Specifically, the controller can periodically collect the real-time bandwidth of the slice to determine whether it is necessary to expand / contract the maximum available bandwidth of the slice.

[0049] Step 110: Determine whether the current real-time bandwidth of the target slice is greater than or equal to a first threshold, wherein the first threshold is the product of the current maximum available bandwidth of the target slice and a first ratio.

[0050] In the embodiment of the present application, assuming that the first ratio is 80%, at the time of initialization, the current maximum available bandwidth of the target slice is the initial value of the maximum available bandwidth (e.g., 100M), then the first threshold is 100M multiplied by 80% equal to 80M. The controller periodically collects the current real-time bandwidth of the target slice and determines whether the current real-time bandwidth of the target slice is greater than or equal to 80M.

[0051] If the current maximum available bandwidth of the target slice is 110M, then the first threshold is 110M multiplied by 80% which equals 88M. The controller periodically collects the current real-time bandwidth of the target slice and determines whether the current real-time bandwidth of the target slice is greater than or equal to 88M.

[0052] As can be seen from the above, the current maximum available bandwidth of the target slice will change dynamically based on the expansion / contraction of the target slice.

[0053] Step 120: If it is determined that the current real-time bandwidth of the target slice is greater than or equal to the first threshold, it is determined whether the current maximum available bandwidth of the target slice has reached the upper limit of the maximum available bandwidth.

[0054] In actual applications, a corresponding maximum available bandwidth upper limit value can also be set for each slice. For example, the initial maximum available bandwidth value set for the target slice is 100M, and the dynamic bandwidth upper limit is set to 30%, that is, the maximum available bandwidth upper limit value set for the target slice is 130M.

[0055] Then, in the embodiment of the present application, when the controller determines that the current real-time bandwidth of the target slice is greater than or equal to the corresponding first threshold, before performing an expansion operation on the current maximum available bandwidth of the target slice, it is necessary to further determine whether the current maximum available bandwidth of the target slice has reached the upper limit of the maximum available bandwidth. If the upper limit of the maximum available bandwidth has been reached, there is no need to increase the current maximum available bandwidth of the target slice.

[0056] Step 130: If it is determined that the current maximum available bandwidth of the target slice does not reach the upper limit of the maximum available bandwidth, the current maximum available bandwidth of the target slice is expanded, wherein the current maximum available bandwidth of the target slice after expansion is not greater than the upper limit of the maximum available bandwidth corresponding to the target slice.

[0057] For example, assuming that the current maximum available bandwidth of the target slice is 100M, the upper limit of the maximum available bandwidth of the target slice is 130M, 100M<130M, and it is determined that the current maximum available bandwidth of the target slice does not reach the upper limit of the maximum available bandwidth. At this time, the current maximum available bandwidth of the target slice can be expanded.

[0058] Specifically, when the current maximum available bandwidth of the target slice is expanded, a preferred implementation method is:

[0059] The current maximum available bandwidth of the target slice is increased by a preset fixed value.

[0060] For example, the expansion bandwidth set for the target slice is a preset fixed value (fixed step size, such as 10M). In this way, when it is determined to expand the target slice, the current maximum available bandwidth of the target slice is increased by 10M.

[0061] When the current maximum available bandwidth of the target slice is expanded, another preferred implementation is:

[0062] Based on the current real-time bandwidth and the current real-time bandwidth of the target slice acquired in the previous period, determine the increase in the real-time bandwidth of the target slice in the current period, and based on the increase, determine the specified value by which the current maximum bandwidth of the target slice needs to be increased, and increase the current maximum available bandwidth of the target slice by the specified value.

[0063] For example, the bandwidth value for capacity expansion set for the target slice is a dynamically changing value, that is, it is calculated based on the real-time bandwidth change value of the slice bandwidth in the current period. The larger the real-time bandwidth change is, the larger the maximum available bandwidth increased this time, and vice versa.

[0064] For example, if the real-time bandwidth change value of the slice bandwidth in the current period is P, the calculated maximum available bandwidth adjustment value is Q; if the real-time bandwidth change value of the slice bandwidth in the current period is 2P, the calculated maximum available bandwidth adjustment value may be 2Q.

[0065] Furthermore, in the embodiment of the present application, the above-mentioned slice loan bandwidth adjustment method may also include the following steps:

[0066] Determine whether the current real-time bandwidth of the target slice is less than or equal to a second threshold, wherein the second threshold is the product of the current maximum available bandwidth of the target slice before the last expansion and the first ratio; if it is determined that the current real-time bandwidth of the target slice is less than the second threshold, and the current maximum available bandwidth of the target slice is greater than the initial value of the maximum available bandwidth, then perform a capacity reduction operation on the current maximum available bandwidth of the target slice, wherein the current maximum available bandwidth of the target slice after the reduction is not less than the initial value of the maximum available bandwidth.

[0067] In the embodiment of the present application, the second threshold is the value of the current maximum available bandwidth before the last expansion of the target slice, that is, assuming that the current maximum available bandwidth of the target slice is 110M, and the current maximum available bandwidth of the target slice before the last expansion is 100M (the initial value of the maximum available bandwidth), then the second threshold is 100M multiplied by 80%, which is equal to 80M. It is determined whether the current real-time bandwidth of the target slice is less than 80M. If it is less than 80M, it is determined whether the current maximum available bandwidth of the target slice is greater than the initial value of the maximum available bandwidth. When it is determined whether the current maximum available bandwidth of the target slice (110M) is greater than the initial value of the maximum available bandwidth (100M), the current maximum available bandwidth of the target slice is reduced.

[0068] Specifically, in the embodiment of the present application, when the current maximum available bandwidth of the target slice is scaled down, a preferred implementation method is:

[0069] The current maximum available bandwidth of the target slice is reduced by a preset fixed value.

[0070] For example, the reduced bandwidth set for the target slice is a preset fixed value (fixed step size, such as 10M), so when it is determined to perform a reduction operation on the target slice, the current maximum available bandwidth of the target slice is reduced by 10M.

[0071] Based on the current real-time bandwidth and the current real-time bandwidth of the target slice acquired in the previous period, determine the reduction amount of the real-time bandwidth of the target slice in the current period, and based on the reduction amount, determine the specified value by which the current maximum bandwidth of the target slice needs to be reduced, and reduce the current maximum available bandwidth of the target slice by the specified value.

[0072] For example, the bandwidth value of the reduction set for the target slice is a dynamically changing value, that is, it is calculated based on the real-time bandwidth change value of the slice bandwidth in the current period. The larger the real-time bandwidth change is, the larger the maximum available bandwidth reduced this time is, and vice versa.

[0073] For example, if the real-time bandwidth change value of the slice bandwidth in the current period is P, the calculated maximum available bandwidth adjustment value is Q; if the real-time bandwidth change value of the slice bandwidth in the current period is 2P, the calculated maximum available bandwidth adjustment value may be 2Q.

[0074] Furthermore, in the embodiment of the present application, before the current maximum available bandwidth of the target slice is reduced, the slice bandwidth adjustment method may further include the following steps:

[0075] It is determined whether the number of times the target slice is shrunk in the shrinking period is greater than or equal to a set value. If the number of times the target slice is shrunk is greater than or equal to the set value, the current maximum available bandwidth of the target slice is not shrunk in the shrinking suppression period.

[0076] Specifically, in actual applications, in order to cope with frequent expansion and contraction operations caused by frequent jitters of business traffic near the threshold, expansion and contraction suppression parameters can be set. When the contraction suppression switch is turned on, you need to enter the contraction period, the number of contractions within the contraction period, and the dynamic contraction suppression period. For example, assuming that the number of dynamic contractions reaches 2 times within 12 minutes, the contraction suppression time is 30 minutes. Of course, you can also turn off the contraction suppression switch according to user needs / specific application scenario requirements. In this way, there is no limit on the frequency of dynamic expansion and contraction.

[0081] The adjustment unit 22 is used to expand the current maximum available bandwidth of the target slice if the judgment unit 21 determines that the current maximum available bandwidth of the target slice has not reached the upper limit value of the maximum available bandwidth, wherein the current maximum available bandwidth of the target slice after expansion is not greater than the upper limit value of the maximum available bandwidth corresponding to the target slice.
