METHOD, APPARATUS, ELECTRONIC DEVICE, AND COMPUTER-READABLE
MEDIUM FOR TRAFFIC CONTROL
BACKGROUND OF THE INVENTION
Technical Field
[0001] The present invention relates to the technical field of computers, and
more particularly
to a method, an apparatus, an electronic device, and a computer-readable
medium for
traffic control.
Description of Related Art
[0002] With the rapid development of network technologies, applications based
on networks
keep increasing in both number and complexity. These applications continuously
devour
network resources, leading to network congestion. For solving network
congestion,
network traffic control has become a hot topic. Network traffic control is
measures to
control network data traffic using software or hardware. To implement it, the
first step is
to build up a traffic control strategy, and then control traffic according to
this strategy. In
the prior art, common traffic control strategies may depend on manual
maintenance by
operations and maintenance personnel or may involve using a linear prediction
model to
make linear prediction of network traffic so as to realize dynamic monitoring
of network
traffic.
[0003] In the known traffic control strategies as describe previously, manual
maintenance is less
flexible and has relatively low traffic usage. While the practice of using a
linear prediction
model to set a traffic control strategy is more flexible than manual
maintenance, a linear
prediction has inherent errors, which can even aggravate when used in complex
scenes,
leading to waste of resources.

[0084] S2 is about using the traffic prediction model to perform traffic
prediction according to
the request data, so as to obtain a prediction result related to a target
cycle. The traffic
prediction model is constructed on the basis of a neural network model.
[0085] Different from the prior art solutions, the embodiment of the present
invention uses a
traffic prediction model constructed on the basis of a network model to
perform traffic
prediction. Traffic prediction is the guide to generation or selection of
traffic control
strategies. Preciseness of traffic prediction results has direct relationship
with the
correctness of generation or selection of a traffic control strategies,
thereby influencing
performance of traffic control. The traffic prediction result may reflect a
specific traffic
value range, or may alternatively be a variation trend of traffic in the
target cycle.
[0086] In one embodiment, prediction is performed through:
[0087] S21: entering the request data to said traffic prediction models of
different prediction
cycles for traffic prediction, so as to obtain the prediction results related
to at least two
different cycles; and
[0088] S22: analyzing the prediction results related to the different cycles,
so as to obtain the
prediction result related to the target cycle.
[0089] The traffic prediction models for different prediction cycles are
plural traffic prediction
models trained respectively using request data collected in different cycles
as training
samples, such as short cycle traffic prediction models, middle cycle traffic
prediction
models, and long cycle traffic prediction models. Correspondingly, the
obtained
prediction results include short cycle prediction results, middle cycle
prediction results,
and long cycle prediction results.
[0090] The prediction results related to different cycles obtained as
described previously are then
analyzed so as to obtain a prediction result related to a target cycle. This
is mainly about
analyzing the prediction results related to cycle of different lengths
comprehensively, so
9
Date Recue/Date Received 2022-03-08
as to ascertain the traffic situation that is related to a cycle as long as
possible, and
conforms, as much as possible, to the actual traffic situation of the target
application in a
cycle as long as possible. Specifically, the foregoing analysis may be as
described in any
one or more of the following embodiments.
[0091] In one embodiment, the step of analyzing the prediction results related
to the different
cycles, so as to obtain the prediction result related to the target cycle
comprises:
[0092] using the prediction result of a short said cycle to correct the
prediction result of a long
said cycle; and
[0093] taking the corrected prediction result of the longer cycle as the
prediction result of the
target cycle.
[0094] The short cycles and the long cycles are identified by sorting the
cycles by length. In the
present embodiment, the step of using the prediction result of a short said
cycle to correct
the prediction result of a long said cycle comprises:
[0095] (1) correcting the prediction result related to the longest cycle
according to the prediction
results related to the other, short cycles; and
[0096] (2) grouping the prediction results of the cycles, and correcting the
prediction results
related to the relatively long cycles according to the prediction results
related to the
relatively short cycles in each group, and then obtaining the prediction
result related to
the target cycle according to the prediction results related to the relatively
long cycles in
each group (particularly, mean calculation, for example).
[0097] Specifically, the foregoing correction may be realized using the ratio
between the
prediction results of the short cycles and the long cycles to correct the
prediction results
of the long cycles, or by setting weights for different cycles. The embodiment
of the
present invention puts no limitation on how the correction is realized.
Date Recue/Date Received 2022-03-08
[0098] In one embodiment, the step of analyzing the prediction results related
to the different
cycles, so as to obtain the prediction result related to the target cycle
comprises:
[0099] performing fit analysis on the prediction results related to the
different cycles, so as to
obtain the prediction result related to the target cycle.
[0100] The fit analysis mainly refers to determining a target function
according to the discrete
prediction results of different cycles by means of adjusting the factor. The
target function
is the one having the smallest difference with the discrete prediction results
of the
different cycles.
[0101] In one embodiment, the step of analyzing the prediction results related
to the different
cycles, so as to obtain the prediction result related to the target cycle
comprises:
[0102] calculating a mean of the prediction results related to the different
cycles; and
[0103] taking the mean of the prediction results related to the different
cycles as the prediction
result of the target cycle.
[0104] The foregoing mean calculation mainly refers to calculating the
arithmetic mean or
weighted mean of the prediction results related to different cycles.
[0105] It is to be noted that, in addition to analysis of the prediction
results of different cycles as
describe above, other approaches may be used to obtain the prediction result
of the target
cycle, including calculating the median of the prediction results of different
cycles, and
taking the median as the prediction result of the target cycle. The median-
based approach
is preferably to be used in cases where the number of cycles is large and the
differences
among different cycles are small.
[0106] In one embodiment, the traffic prediction model is constructed through:
[0107] S21 ': acquiring a sample training set for traffic prediction, which
includes input samples
11
Date Recue/Date Received 2022-03-08
and result samples;
[0108] S22': inputting the input sample to the initialized neural network
model, so as to obtain a
prediction result set;
[0109] S23': comparing the prediction result set to the result samples, so as
to obtain prediction
errors;
[0110] S24': based on prediction errors adjusting neural network model;
[0111] S25': using the adjusted neural network model to repeatedly make
prediction based on
the input samples; and
[0112] S26': comparing the prediction errors to standard error conditions, and
when the
prediction errors satisfy the standard error conditions, determining that the
neural network
model corresponding to the prediction errors is the traffic prediction model.
[0113] In S22', the initialized neural network model has an initialized
weight. In S24', the
synapse weights of the neural network model are corrected according to
prediction errors
using a backpropagation algorithm. Thereby, the traffic prediction model
constructed as
described in the embodiment of the present invention has the ability of
adaptive learning,
and can continuously adjusting synapse weights by comparing the prediction
errors and
standard errors, thereby eliminating the defects of the conventional methods
about
inability to predict sudden incidents.
[0114] S3: generating a traffic control strategy according to the prediction
result of the target
cycle.
[0115] The traffic control strategy may be generated according to the
prediction result, or may
alternatively be selected from pre-loaded ones that correspond to different
prediction
results.
[0116] S4 is about controlling the traffic of the target application in the
target cycle according to
the traffic control strategy.
[0117] As described above, with the relatively precise traffic prediction
result, a targeted traffic
control strategy may be generated, thereby achieving effective traffic control
for the target

semiconductor system, apparatus, or device, or any combination thereof. Morre
particular
examples of the computer-readable storage medium may include but are not
limited to
electric connection having one or more leads, a portable computer disk, a hard
drive, a
random-access memory (RAM), a read-only memory (ROM), an electrically erasable
programmable read-only memory (EPROM or flash), an optical fiber, a compact
disc
read-only memory (CD-ROM), an optical memory, a magnetic memory, or any
suitable
combination thereof. In embodiments of the present invention, the computer-
readable
storage medium may be any tangible medium that contains or stores a program.
The
program may be used by or with an instruction-executing system, an apparatus
or a device.
In embodiments of the present invention, the computer-readable signal medium
may
comprise data signals that are propagated in the baseband or propagated as a
part of carrier
waves, and carry computer-readable program codes. The propagatable data
signals may
be in various forms including, but not limited to, electromagnetic signals,
optical signals,
or any suitable combination thereof. The computer-readable signal medium may
alternatively be any computer-readable medium other than a computer-readable
storage
medium. The computer-readable signal medium may transmit, propagate, or send a
program that is to be used by or with an instruction-executing system, an
apparatus or a
device. The program codes contained in the computer-readable medium may be
transmitted through any suitable medium, including but not limited to: a power
cord, an
optical cable, RF (Radio Frequency), or any suitable combination thereof.

[0160] The computer-readable medium may be contained in the aforementioned
server, or may
alternatively exist separately instead of being installed in the server. The
computer-
readable medium carries one or more programs. When executed by the server, the
one or
more programs make the server: in response to its detection result indicating
that the
accessory mode of a terminal is not activated, acquire the frame rate of the
application on
the terminal; when the frame rate satisfies screen-off conditions, determine
whether a user
is acquiring the screen information of the terminal; and in response to its
determination
result indicating that the user is not acquiring the screen information of the
terminal,
control the screen to enter the screen-off mode.
[0161] The computer program codes for executing operations of the embodiment
of the present
invention may be written in one or more program design languages or a
combination
thereof. The program design languages may include object-orientated program
design
languages, such as Java, Smalltalk, C++, and may further include conventional
procedural program design languages, such as "C" or the like. The program
codes may
be completely executed on a user computer, partially executed on a user
computer,
executed as an independent software package, partially executed on a user
computer and
partially executed on a remote computer, or completely executed on a remote
computer
or server. Where a remote computer is involved, the remote computer may be
connected
to the user computer through any kind of networks, such as a local area
network (LAN)
or a wide area network (WAN), or may be connected to an external computer
(such as by
using an Internet service provider through the Internet).
[0162] The embodiments of the present invention provide the following
technical effects:
[0163] 1. In the embodiment of the present invention, the neural network model
provides precise
traffic prediction, so that traffic monitoring strategies specific to
prediction results can be
generated, thereby facilitating reasonable distribution of the traffic, and
enabling warning

Date Recue/Date Received 2022-03-08
of potential traffic bursts to be given according to prediction results;
[0164] 2. The technical scheme of the embodiment of the present invention
performs analysis
according to the traffic prediction results related to different prediction
cycles so as to
obtain a prediction result related to a target cycle, which is more precise
than the
prediction result obtained using the known linear prediction method; and
[0165] 3. The technical scheme of the embodiment of the present invention
continuously trains
and adjusts the traffic prediction model according to prediction errors,
thereby
eliminating the defects of the conventional methods about inability to predict
sudden
incidents.
