Background

In order to meet the requirement of remote transmission, forwarding or storage of data, the current data transmission network builds a relatively complex network topology model, and invests more infrastructure resource construction. In order to better fully utilize these infrastructure resources, the data transmission network needs to be extended with the bandwidth requirements of the upper layer service, so as to meet the bandwidth requirements of the upper layer service.

In the method, the adjustment of the network bandwidth only refers to the traffic transmission condition of the current upper layer service, and with the increase of the traffic volume and the diversification of the traffic flow in the data transmission network, the bandwidth requirement of the service cannot be met and the network resource cannot be fully utilized by expanding the infrastructure resource. For example, when the traffic exceeds the reserved traffic bandwidth, the traffic needs to be controlled by increasing the traffic delay so as not to exceed the reserved bandwidth, thereby affecting the traffic transmission efficiency; in addition, if the traffic flow is lower than the reserved bandwidth for a long time, and other traffic cannot use the part of bandwidth resources, the waste of network resources is caused.

In the bandwidth adjustment method provided by the embodiment of the invention, the bandwidth corresponding to the target service is judged in real time according to the acquired service model data (namely the basic data and the transmission data corresponding to the target service), so that the bandwidth of the target service is adjusted in real time, the transmission requirement of service traffic can be rapidly and effectively met, and the total bandwidth of a physical link can be adjusted in real time, so that the utilization rate of network resources is effectively improved.

In one design, the base data includes a traffic preset bandwidth, the transmission data includes an instantaneous transmission traffic, and the first bandwidth utilization is an instantaneous bandwidth utilization. In order to determine the bandwidth adjustment mode and the bandwidth adjustment amount corresponding to the target service according to the instantaneous bandwidth utilization corresponding to the target service, as shown in fig. 3, in the bandwidth adjustment method provided by the embodiment of the present invention, the step in S202 may specifically include the following steps S301 to S304:

S301, determining the instantaneous bandwidth utilization rate corresponding to the target service based on the service preset bandwidth and the instantaneous transmission flow.

It should be noted that, the service preset bandwidth is a bandwidth configuration parameter preconfigured for the target service by the server, that is, the maximum bandwidth that can be achieved by the target service when transmitting the traffic. The instantaneous transmission flow is instantaneous flow data acquired in real time when the target service transmits the flow.

As a possible implementation manner, the above-mentioned instantaneous bandwidth utilization may be obtained by calculating a ratio of the instantaneous transmission traffic to the traffic preset bandwidth.

S304, increasing the bandwidth corresponding to the target service based on the bandwidth adjustment amount under the condition that the instantaneous bandwidth utilization is greater than or equal to the first threshold.

As one possible implementation manner, when it is determined that the instantaneous bandwidth utilization is greater than or equal to the first sub-threshold and the time interval between two adjacent determinations of the magnitude relation between the instantaneous bandwidth utilization and the threshold is greater than or equal to the preset time interval, it may be determined that the bandwidth corresponding to the target service needs to be increased.

As a possible implementation manner, when it is determined that the instantaneous bandwidth utilization is greater than the second sub-threshold and less than the first sub-threshold, it may be determined that there is no need to adjust the bandwidth corresponding to the target service.

In one design, the underlying data includes a total bandwidth of the traffic, the transmitted data includes a total transmission traffic, and the first bandwidth utilization is an average bandwidth utilization; in order to determine the bandwidth adjustment manner and the bandwidth adjustment amount corresponding to the target service according to the average bandwidth utilization corresponding to the target service, as shown in fig. 4, in the bandwidth adjustment method provided by the embodiment of the present invention, the step in S202 may specifically include the following steps S401 to S404:

s401, determining the average bandwidth utilization rate corresponding to the target service based on the total bandwidth and the total transmission flow of the service.

It should be noted that, the total bandwidth of the service is determined according to the service bandwidth and the duration, that is, the maximum flow that the target service can transmit in a certain duration. The total transmission flow is the total flow transmitted by the target service in a certain time period.

Alternatively, the average bandwidth utilization may be obtained by calculating a ratio of a total bandwidth of the service to a total transmission traffic.

Optionally, in the process of determining the average bandwidth utilization rate corresponding to the target service, the total bandwidth and the total transmission flow of the service corresponding to the target service may be collected once every preset time interval, so as to determine whether the bandwidth corresponding to the target service needs to be adjusted.

S402, judging the size relation between the average bandwidth utilization rate and the first threshold value, determining a bandwidth adjustment mode corresponding to the target service, judging the difference value between the average bandwidth utilization rate and the first threshold value, and determining the bandwidth adjustment quantity corresponding to the target service.

As one possible implementation manner, determining that the bandwidth corresponding to the target service needs to be increased when the average bandwidth utilization is greater than or equal to the first sub-threshold; and determining that the bandwidth corresponding to the target service needs to be reduced under the condition that the average bandwidth utilization rate is smaller than or equal to the second sub-threshold value.

As a possible implementation, the bandwidth adjustment amount may be determined by calculating a difference between the average bandwidth utilization and the first threshold value, and determining the bandwidth adjustment amount according to the difference, the smaller the difference, the larger the bandwidth adjustment amount.

S403, reducing the bandwidth corresponding to the target service based on the bandwidth adjustment amount under the condition that the average bandwidth utilization rate is smaller than the first threshold value.

As one possible implementation, when it is determined that the average bandwidth utilization is less than or equal to the second sub-threshold, it may be determined that the bandwidth corresponding to the target traffic needs to be reduced.

As one possible implementation, when it is determined that the average bandwidth utilization is greater than or equal to the first sub-threshold, it may be determined that the bandwidth corresponding to the target traffic needs to be increased.

As a possible implementation manner, when it is determined that the average bandwidth utilization is greater than the second sub-threshold and less than the first sub-threshold, it may be determined that the bandwidth corresponding to the target service does not need to be adjusted.

Optionally, when determining that the bandwidth configuration parameters of the target service need to be adjusted, sending the bandwidth adjustment mode and the bandwidth adjustment amount to a corresponding processing unit (for example, a network element device) to adjust the bandwidth configuration parameters of the target service, and simultaneously updating service model data (for example, service bandwidth information) corresponding to the target service in the database summary.

In one design, in order to determine the bandwidth adjustment manner and the bandwidth adjustment amount corresponding to the target physical link, as shown in fig. 5, in the bandwidth adjustment method provided by the embodiment of the present invention, the steps S203 to S505 may specifically include the following steps S501 to S505:

S501, determining the used bandwidth amount of the target physical link according to the bandwidth adjustment mode and the bandwidth adjustment amount corresponding to each service in the plurality of services.

As a possible implementation manner, after determining the bandwidth adjustment manner and the bandwidth adjustment amount corresponding to each service in the plurality of services executed by the target physical link, the current bandwidth configuration parameter of each service may be determined.

Further, the amount of bandwidth used by the target physical link may be determined based on the current bandwidth configuration parameters for each service.

S502, determining a second bandwidth utilization rate based on the used bandwidth amount of the target physical link and the total bandwidth amount of the target physical link.

As a possible implementation manner, the second bandwidth utilization may be obtained by calculating a ratio of the amount of bandwidth used by the target physical link and the total amount of bandwidth of the target physical link.

Specifically, the used bandwidth amount of the target physical link and the total bandwidth amount of the target physical link may be imported into a corresponding network computing module, so as to calculate and obtain the second bandwidth utilization rate corresponding to the target physical link.

It should be noted that, the amount of the used bandwidth of the target physical link may be understood as: the total amount of bandwidth that has been configured for all traffic executing on the target physical link. The target total amount of physical link bandwidth can be understood as: the amount of bandwidth available on the target physical link includes an amount of allocated bandwidth and an amount of unallocated bandwidth.

S503, judging the size relation between the second bandwidth utilization rate and the second threshold value, determining the bandwidth adjustment mode corresponding to the target physical link, judging the difference value between the second bandwidth utilization rate and the second threshold value, and determining the bandwidth adjustment quantity corresponding to the target physical link.

Optionally, the second threshold may include a third sub-threshold and a fourth sub-threshold, where the third sub-threshold is greater than the fourth sub-threshold.

As a possible implementation, the bandwidth adjustment amount may be determined by calculating a difference between the second bandwidth utilization and the threshold (i.e., the third sub-threshold or the fourth sub-threshold), and determining the bandwidth adjustment amount according to the difference, the smaller the difference, the larger the bandwidth adjustment amount.

S504, when the second bandwidth utilization rate is smaller than a second threshold value, reducing the bandwidth corresponding to the target physical link based on the bandwidth adjustment amount.

As one possible implementation, in the case where the second bandwidth utilization is less than or equal to the fourth sub-threshold, it is determined that the target physical link total bandwidth needs to be reduced.

S505, when the second bandwidth utilization is greater than or equal to the second threshold, increasing the bandwidth corresponding to the target physical link based on the bandwidth adjustment amount.

As one possible implementation, in the case where the second bandwidth utilization is greater than or equal to the third sub-threshold, it is determined that the target physical link total bandwidth needs to be increased.

As one possible implementation, when the second bandwidth utilization is determined to be greater than the fourth sub-threshold and less than the third sub-threshold, it may be determined that no adjustment to the target physical link total bandwidth is required.

Optionally, after adjusting the total bandwidth of the target physical link, the network model data corresponding to the target physical link in the database summary (i.e., the total bandwidth of the target physical link) needs to be updated at the same time.

In one design, in order to accurately determine the second bandwidth utilization corresponding to the target physical link, as shown in fig. 6, in the bandwidth adjustment method provided by the embodiment of the present invention, the step in S502 may specifically include the following S5021:

s5021, determining a second bandwidth utilization based on the amount of bandwidth used by the target physical link, the total amount of bandwidth of the target physical link, and the amount of traffic performed by the target physical link.

As a possible implementation manner, when calculating the second bandwidth utilization rate corresponding to the target physical link, a more accurate second bandwidth utilization rate may be obtained according to the total traffic carried by the target physical link.

It should be noted that, the total traffic amount may be understood as: the total amount of traffic carried by the target physical link. The total number of traffic may account for the concurrent demand of all traffic carried in the target physical link, such as: when the total number of the services is smaller, the concurrency possibility is small (namely, the quantity of the simultaneously transmitted service data is smaller), and the quantity of the reserved bandwidth is also smaller; when the total number of services is larger, the concurrency possibility is high, and the reserved bandwidth amount is larger.

Alternatively, the first value may be obtained by calculating the product of the amount of bandwidth used by the target physical link and the conventional coefficient α, and then calculating the ratio of the product to the total amount of bandwidth of the target physical link; further calculating the product of the total number of traffic and the normal coefficient beta to obtain a second value, thereby determining the sum of the first value and the second value as a second bandwidth utilization.

As one possible implementation manner, in the case that the second bandwidth utilization is smaller than or equal to the fourth sub-threshold, and the time interval between two adjacent determinations of the magnitude relation between the second bandwidth utilization and the threshold is greater than or equal to a preset time interval, it is determined that the target physical link total bandwidth needs to be reduced.

As one possible implementation manner, in the case that the second bandwidth utilization is greater than or equal to the third sub-threshold, and the time interval between two adjacent determinations of the magnitude relation between the second bandwidth utilization and the threshold is greater than or equal to a preset time interval, it is determined that the target physical link total bandwidth needs to be increased.

The bandwidth adjusting method flexibly adjusts the service configuration bandwidth parameters by judging whether the service bandwidth utilization rate exceeds the threshold value, and controls the frequency of service bandwidth adjustment by using the threshold value and the time period. Based on the calculation, the total bandwidth of the physical link can be adjusted according to the total bandwidth utilization rate and the total number of services corresponding to the physical link, so that the situation of the allocable bandwidth corresponding to the physical link is reflected through the utilization rate of the total bandwidth of the physical link, the possibility of service concurrency in the physical link is reflected through the total number of services, and the total bandwidth of the physical link is flexibly controlled by using the two data.
