Technical Field

Background

In order to meet the requirement of remote transmission, forwarding or storage of data, the current data transmission network constructs a relatively complex network topology model and invests in more infrastructure resource construction. In order to make better use of these infrastructure resources, the data transmission network needs to expand the infrastructure resources along with the bandwidth requirements of the upper layer services, so as to meet the bandwidth requirements of the upper layer services.

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 in the data transmission network and the diversification of the traffic, the bandwidth requirement of the service cannot be met and the network resources cannot be fully utilized by expanding the infrastructure resources. For example, when the traffic flow exceeds the reserved traffic bandwidth, the traffic delay needs to be increased to control the traffic flow 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 services cannot use the part of the bandwidth resources, the network resources are wasted.

In one design, the base data includes a traffic preset bandwidth, the transport data includes instantaneous transport traffic, and the first bandwidth utilization is an instantaneous bandwidth utilization. In order to determine a bandwidth adjustment manner and a bandwidth adjustment amount corresponding to a target service according to an instantaneous bandwidth utilization rate corresponding to the target service, as shown in fig. 3, in the bandwidth adjustment method provided in 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 that is configured in advance for the target service by the server, that is, the maximum bandwidth that can be achieved when the target service transmits the traffic. The instantaneous transmission flow is instantaneous flow data acquired in real time when the target service transmits the flow.

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

As a 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 relationship 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 smaller than the first sub-threshold, it may be determined that the bandwidth corresponding to the target service does not need to be adjusted.

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

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

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

Optionally, the average bandwidth utilization may be obtained by calculating a ratio of the total bandwidth of the service to the 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 a first threshold value, determining a bandwidth adjusting 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 adjusting quantity corresponding to the target service.

As a possible implementation manner, determining that the bandwidth corresponding to the target service needs to be increased when the average bandwidth utilization rate 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 less than or equal to the second sub-threshold.

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

And 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 a possible implementation manner, 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 service needs to be reduced.

As a possible implementation manner, 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 service 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 smaller 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 parameter of the target service needs to be adjusted, the bandwidth adjustment mode and the bandwidth adjustment amount are sent to the corresponding processing unit (e.g., network element device) to adjust the bandwidth configuration parameter of the target service, and simultaneously update service model data (e.g., service bandwidth information) corresponding to the target service in the database summary.

In a design, in order to determine a bandwidth adjustment manner and a bandwidth adjustment amount corresponding to a target physical link, as shown in fig. 5, the steps from S203 to S505 may specifically include the following steps:

s501, determining the used bandwidth amount of the target physical link according to the bandwidth adjusting mode and the bandwidth adjusting amount corresponding to each service in the plurality of services.

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

Further, the amount of the used bandwidth of the target physical link can be determined according to the current bandwidth configuration parameter of each service.

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

As a possible implementation manner, the second bandwidth utilization rate may be obtained by calculating a ratio of the used bandwidth amount of the target physical link and the total bandwidth amount 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 introduced into the corresponding network computing module to compute and obtain the second bandwidth utilization rate corresponding to the target physical link.

It should be noted that, the above-mentioned amount of bandwidth used by the target physical link can be understood as: the total amount of bandwidth that has been configured on the target physical link for all traffic that is performed. The target physical link total bandwidth amount 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 relationship between the second bandwidth utilization rate and the second threshold, 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, and determining the bandwidth adjustment amount corresponding to the target physical link.

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

As a possible implementation manner, 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, wherein the smaller the difference is, the larger the bandwidth adjustment amount is.

And S504, reducing the bandwidth corresponding to the target physical link based on the bandwidth adjustment amount under the condition that the second bandwidth utilization rate is smaller than the second threshold value.

As a possible implementation, in a case that 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.

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

As a possible implementation, in a case that 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 a possible implementation manner, in the case that it is determined that the second bandwidth utilization rate is greater than the fourth sub-threshold and less than the third sub-threshold, it may be determined that the target physical link total bandwidth does not need to be adjusted.

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

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

s5021, determining a second bandwidth utilization rate based on the used bandwidth amount of the target physical link, the total bandwidth amount of the target physical link and the number of services executed 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 amount of traffic carried by the target physical link.

It should be noted that the total amount of traffic may be understood as: the total amount of traffic carried by the target physical link. The total amount of traffic may indicate the concurrent demand of all the services carried in the target physical link, for example: when the total number of services is small, the concurrency probability is small (that is, the amount of service data transmitted at the same time is small), and the amount of bandwidth required to be reserved is also small; when the total amount of the services is larger, the concurrency probability is higher, and the amount of the bandwidth needing to be reserved is larger.

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

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

The bandwidth adjustment method provided by the patent flexibly adjusts the service configuration bandwidth parameter by judging whether the service bandwidth utilization rate exceeds the threshold, and controls the frequency of service bandwidth adjustment by setting the threshold and the time period.
