Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.
The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in this application and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
In order to make the technical solutions provided in the embodiments of the present application better understood and make the above objects, features and advantages of the embodiments of the present application more comprehensible, the technical solutions in the embodiments of the present application are described in further detail below with reference to the accompanying drawings.
Referring to fig. 1, fig. 1 is a flowchart of a method provided in an embodiment of the present application. Alternatively, as an embodiment, the flow may be applied to an electronic device. As an embodiment, the electronic device here may be a device related to service forwarding in network communication, for example, a network device on a service packet forwarding path such as a server, an exchange, and a base station, which is not limited in this embodiment.
In this embodiment, the flow shown in fig. 1 is forwarding control performed for a target service, and if a plurality of services exist in a system, corresponding service forwarding control may be performed on each service according to the flow shown in fig. 1.
As shown in fig. 1, the process may include the following steps:
In this embodiment, for the target service, a port for forwarding the target service, referred to as a target port, may exist on the electronic device.
In addition, in the embodiment, the designated period may be set according to actual requirements, and the embodiment is not particularly limited.
In this embodiment, there are many implementation manners in the step 101, and fig. 2 shows one of the implementation manners by way of example, which is not described herein again.
And step 102, adjusting the token generation rate of a token bucket for controlling the flow of the target service according to the target service sending rate, generating tokens according to the adjusted token generation rate, and storing the tokens into the token bucket.
In this embodiment, the target traffic may be forwarded under control of a token bucket. When a service packet of a target service is received and the service packet needs to be forwarded, the token in the token bucket can be consumed and the service packet can be forwarded, and when the token in the token bucket is insufficient, the service packet cannot be forwarded. In the prior art, in a specific implementation, the token bucket generates tokens at a fixed rate and stores the tokens into the token bucket, and in this embodiment, the dynamic adjustment is performed on the tokens generated in the token bucket, which does not generate tokens at a fixed rate, but adjusts the token generation rate of the token bucket for controlling the flow of the target traffic according to the target traffic sending rate.
Optionally, how to adjust the token generation rate of the token bucket for performing flow control on the target traffic according to the target traffic sending rate has many implementation manners, and fig. 3 illustrates one of the implementation manners, which is not described herein again.
In this embodiment, once the token generation rate is adjusted, tokens can be subsequently generated according to the adjusted token generation rate and stored in the token bucket.
And 103, when data forwarding is performed, controlling and forwarding the service packet cached in the service cache space according to the total amount of the current token in the token bucket and the service packet cached in the service cache space corresponding to the target service.
Optionally, in this embodiment, the total amount of current tokens in the token bucket may be a current token amount of the token bucket, which may be obtained intuitively.
In this embodiment, as described above, once the token generation rate is adjusted, the tokens may be subsequently generated according to the adjusted token generation rate and stored in the token bucket, and based on this, in this step 103, the total amount of the current tokens in the token bucket may be determined according to the adjusted token generation rate. For example, if the data forwarding in step 103 is the first forwarding after adjusting the token generation rate, the total number of tokens currently in the token bucket can be determined by the following steps:
step a1, a historical token quantity in the token bucket is obtained, the historical token quantity being the number of tokens held in the token bucket before the token generation rate is adjusted.
Step a2, determining the total amount of current tokens in the token bucket according to the historical token amount and the quantity of tokens generated and stored in the token bucket according to the adjusted token generation rate.
Alternatively, in one case, when the sum of the historical token amount and the number of tokens generated and stored to the token bucket according to the adjusted token generation rate is greater than the token capacity upper limit of the token bucket, the token capacity upper limit of the token bucket may be directly determined as the current token total amount. In other cases, the historical token amount and the sum of the token amounts of the number of tokens generated according to the adjusted token generation rate and stored in the token bucket may be directly determined as the current total token amount.
It should be noted that the current token total determined in steps a1 and a2 is only performed on the premise that the data forwarding in step 103 is performed on the first forwarding after the token generation rate is adjusted, and on other premises, the current token total in the token bucket can be finally presented in a similar manner.
As to how to determine the service packet cached in the service cache space corresponding to the target service in this step 103, there are many implementation manners, and fig. 4 illustrates one of the implementation manners, which is not described herein for the moment; how to control and forward the service packets cached in the service cache space according to the total amount of the current token in the token bucket and the service packets cached in the service cache space corresponding to the target service also has many embodiments, and fig. 5 illustrates one of the embodiments, which is not described herein for the time being.
Thus, the flow shown in fig. 1 is completed.
As can be seen from the flow shown in fig. 1, in this embodiment, by obtaining the sending rate of the target service, adjusting the token generation rate, and using the dynamic adjustment of the token generation rate, the current total token amount in the token bucket for performing flow control on the target service is indirectly adjusted, so that when data forwarding is required, dynamic service forwarding control can be implemented according to the current total token amount in the token bucket and the service packet of the target service. When the actually needed resources of the current service packet to be forwarded are smaller than the existing network resources of the target service, the resources can be dynamically and adaptively adjusted according to the actually needed resources of the current service packet to be forwarded, so that the waste of network resources is reduced.
One implementation of the above step 101 is described in detail below with reference to the flowchart shown in fig. 2.
As shown in fig. 2, one implementation of step 101 may include the following steps:
step 101_1, determine whether the target period of the statistical target service rate is reached.
If the target service rate counting period is reached, executing step 101_2, otherwise, continuing to wait until the target service rate counting period is reached.
And step 101_2, counting the service sending reference rate in the target period.
And acquiring the target service data transmission quantity in the target period, calculating the service transmission reference rate, and if the target service does not transmit data in the target period, considering the service transmission reference rate as 0.
Optionally, as an embodiment, there are many ways of sending the reference rate of the traffic in the statistical target period, for example, the following equation 1 may be used to implement:
rprd ═ S/T (equation 1)
Wherein Rprd is a service sending reference rate, S is a total amount of data sent by the target service in the target period, if the target service in the target period does not send data, S is 0, and T is a time length of the target period.
And step 101_3, smoothing the service transmission reference rate to obtain a target service transmission rate.
As an optional embodiment, the Service transmission reference rate is smoothed, and at least one of the purposes of the smoothing and the smoothing is to satisfy the rate requirement of the target Service at the target Service transmission rate obtained after the smoothing is guaranteed (the rate requirement is determined according to the Quality of Service (QoS) set for the target Service).
Optionally, as an embodiment, there are many ways to calculate the smoothing process, for example, the following equation 2 can be used to implement:
r ═ α × R + (1- α) × (Rprd (formula 2)
Wherein, R is a target service sending rate, α is a smoothing coefficient, and has a value range of 0 to 1, the larger the value of α is, the more R can represent a transmission rate of long-time statistical significance, and the smaller the value of α is, the more R can represent a recent transmission rate.
To this end, one implementation of step 101 shown in fig. 2 is completed.
In the following, a detailed description is given of one implementation manner of how to adjust the token generation rate of the token bucket for controlling the flow of the target traffic according to the sending rate of the target traffic in step 102, in conjunction with the flow shown in fig. 3.
As shown in fig. 3, one implementation of how to adjust the token generation rate of the token bucket for controlling the flow of the target traffic according to the target traffic sending rate in step 102 may include the following steps:
step 102_1, judging whether the target service sending rate is greater than a first set threshold.
Optionally, the first set threshold may be set according to a rate requirement of the target service, or may be associated with a token generation rate, and the first set threshold is adjusted after the token generation rate is adjusted.
The Rate requirement of the target service may be a Maximum Bit Rate (MBR) requirement for a Maximum Bit Rate (MBR) of Guaranteed Bit Rate (GBR) service and a GBR requirement for a lower limit of the Rate, or a Rate requirement set according to other rules or requirements, which is not limited in this embodiment.
Optionally, as an embodiment, there are many ways to set the first setting threshold, for example, the following equation 3 may be used to set:
thup (token rate) factor1 (equation 3)
Wherein, Thup is a first set threshold, token rate is a token generation rate, factor1 is a first threshold coefficient, the value range is 0-1, and the larger the value of factor1 is, the more difficult the token rate is to be adjusted upwards.
And when R is greater than Thup, judging that the target service sending rate is greater than a first set threshold, and executing a step 102_2, otherwise, executing a step 102_ 3.
For example, when the factor1 is 0.7, the threshold rate representing the first set threshold is 0.7 times the token generation rate, i.e., when the target traffic sending rate is greater than 0.7 times the token generation rate, the token generation rate needs to be adjusted up.
Step 102_2, adjust token generation rate up.
When the target service sending rate is greater than the first set threshold, it may be considered that the network resources are sufficient, and may attempt to allocate more network resources to the service packet, and it is necessary to adjust the token generating rate up, optionally, as an embodiment, there are many ways to adjust the token generating rate up, for example, the following equation 4 may be used to adjust up:
token rate MIN (MBR, token rate upsstep) (formula 4)
The token rate is a token generation rate, the MBR represents an upper limit of a rate of a service, and the token generation rate cannot exceed the upper limit, so that a smaller value between the MBR and the token rate upStep is obtained, the upStep is a token rate up-regulation coefficient, the value of the upStep is greater than 1, and the larger the value of the upStep is, the larger the amplitude of single upscaling of the token rate is under the premise that the MBR is not exceeded.
And step 102_3, judging whether the target service sending rate is less than a second set threshold.
Optionally, the second set threshold may be set according to a rate requirement of the target service, or may be associated with a token generation rate, and when the second set threshold is adjusted, the second set threshold is also adjusted, and the setting manner of the second set threshold is not limited in this embodiment.
Optionally, as an embodiment, there are many ways to set the second setting threshold, for example, the following equation 5 may be used to set:
thdown (token rate) factor2 (formula 5)
Wherein, Thdown is a second set threshold, the factor2 is a second threshold coefficient, the value range is 0 to 1, and the smaller the value of the factor2 is, the less the token rate is adjusted downwards.
And when R < Thdown, judging that the target service sending rate is less than a second set threshold, executing a step 102_4, otherwise executing a step 102_ 5.
For example, when the factor2 is 0.5, the threshold rate representing the second set threshold is 0.5 times the token generation rate, that is, when the target traffic sending rate is less than 0.5 times the token generation rate, the token generation rate needs to be decreased.
Step 102_4, the token generation rate is adjusted downward.
When the target service sending rate is less than the second set threshold, it may be considered that the network resources are insufficient, and it may try to reduce the network resources allocated to the service packet, so as to save the limited network resources and preferentially guarantee the minimum rate requirement. The token generation rate needs to be adjusted downward, and optionally, as an embodiment, there are many ways to adjust the token generation rate downward, for example, the following equation 6 can be used to adjust downward:
token rate MAX (GBR, token rate down step) (equation 6)
Wherein GBR represents the lower limit of the rate of the traffic, the token generation rate must not be lower than the lower limit,
therefore, the larger value of the GBR and the token rate descending step is taken, the descending step is a token rate descending coefficient and ranges from 0 to 1, and the smaller the descending step is, the larger the amplitude of single descending of the token rate is on the premise that the GBR is not lower.
In step 102_5, the token generation rate is unchanged.
When the target service sending rate does not exceed the first set threshold and is not lower than the second set threshold, the token generation rate is appropriate at the moment, and no adjustment is needed.
The flow shown in fig. 3 is completed.
In the following, a detailed description is given, with reference to the flow shown in fig. 4, on how to determine one implementation manner of the service packet cached in the service cache space corresponding to the target service in step 103.
As shown in fig. 4, one implementation manner of how to determine the service packet cached in the service cache space corresponding to the target service in step 103 may include the following steps:
and step 103_1, receiving the current service packet, and judging whether the service cache space is full.
When the electronic device receives the current service packet, it determines whether the service cache space is full, if the service cache space is full, step 103_2 is executed, and if the service cache space is not full, step 103_3 is executed. The service cache space is a space for temporarily storing the service packet after the device receives the service packet until the service packet is forwarded and leaves the service cache space.
And step 103_2, discarding the current service packet.
When the electronic equipment receives the current service packet, if the service cache space is full, the current service packet is discarded. Optionally, the service packet discarding situation can be reduced by expanding the service buffer space capacity.
And step 103_3, caching the current service packet.
When the electronic equipment receives the current service packet, if the service cache space is not full, the current service packet is cached and enters the service cache space.
Optionally, the service packets cached in the service cache space are sequenced according to the sequence of the caching time, so that when the service forwarding control is performed subsequently, the forwarding is performed according to the sequence of the service packets in the service cache space.
The flow shown in fig. 4 is completed.
In the following, a specific description is given, with reference to the flow shown in fig. 5, on how to perform control forwarding on the service packet cached in the service cache space according to the total amount of the current token in the token bucket and the service packet cached in the service cache space corresponding to the target service in step 103.
As shown in fig. 5, one implementation manner of how to control and forward the service packets cached in the service cache space according to the total amount of the current tokens in the token bucket and the service packets cached in the service cache space corresponding to the target service in step 103 may include the following steps:
and step 103_4, judging whether the token quantity required by the service packet cached in the service cache space is less than the total quantity of the current tokens in the token bucket.
When data forwarding is performed, if the quantity of tokens required by the service packets cached in the service cache space is less than the total quantity of current tokens in the token bucket, step 103_5 is performed, otherwise, step 103_6 is performed.
And step 103_5, scheduling network resources matched with the service packets cached in the service cache space.
And when the token quantity required by the service packet cached in the service cache space corresponding to the target service is less than the total quantity of the current tokens in the token bucket, scheduling network resources matched with the service packet cached in the service cache space, and forwarding the service packet cached in the service cache space through the scheduled network resources.
Optionally, the network Resource may be a Resource required for forwarding a service packet in network communication, such as a bandwidth Resource, a spectrum Resource, and the like, which is not limited in this embodiment, for example, as a specific embodiment, when the electronic device is a base station in a 5G network, the network Resource may be a Resource Block (RB) Resource, and the following network resources are the same.
And step 103_6, scheduling network resources matched with the current total token amount in the token bucket.
When the token quantity required by the service package cached in the service cache space corresponding to the target service is greater than the current token total quantity in the token bucket, scheduling network resources matched with the current token total quantity in the token bucket, and forwarding part of the service package cached in the service cache space through the scheduled network resources, wherein the part of the service package cached in the service cache space is the service package of which the required network resources are less than or equal to the scheduled network resources.
Optionally, the service packets cached in the service cache space may be sorted according to the order of the caching time, and a part of the service packets matching the scheduled network resource is selected from the sequence according to the order, and the selected part of the service packets is forwarded.
The flow shown in fig. 5 is completed.
