Detailed Description
Embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
The embodiment of the invention provides a regulation and control method, a storage medium, electronic equipment and a system for screenshot service.
In order to achieve the technical effects, the general idea of the application is as follows:
a regulation and control method for screenshot service comprises the following steps:
s1, monitoring the residual stream resources, the current limiting operation frequency, the screenshot frequency and the screenshot failure rate of the client side in the live broadcast;
s2, when the residual flow resource is larger than the preset resource residual threshold or the screenshot failure rate is larger than the preset first failure threshold, reducing the total resource amount of the residual flow resource and reducing the subsequent resource distributed to the residual flow resource;
and S3, when the current limiting operation frequency is greater than the preset current limiting frequency threshold and the screenshot failure rate is less than the preset second failure threshold, increasing the total resource amount of the residual stream resources and increasing the resources subsequently distributed to the residual stream resources.
Example one
Referring to fig. 1, an embodiment of the present invention provides a regulation and control method for screenshot service, including the following steps:
s1, monitoring the residual stream resources, the current limiting operation frequency, the screenshot frequency and the screenshot failure rate of the client side in the live broadcast;
s2, when the residual flow resource is larger than the preset resource residual threshold or the screenshot failure rate is larger than the preset first failure threshold, reducing the total resource amount of the residual flow resource and reducing the subsequent resource distributed to the residual flow resource;
and S3, when the current limiting operation frequency is greater than the preset current limiting frequency threshold and the screenshot failure rate is less than the preset second failure threshold, increasing the total resource amount of the residual stream resources and increasing the resources subsequently distributed to the residual stream resources.
It should be noted that the stream resource is a resource in a data stream form that is allocated to the client by the server and is required for data transmission;
in addition, the current limiting operation is specifically that the residual stream resources of the live broadcast room client are zero, and the subsequent operation needing to use the residual stream resources is directly returned.
In the embodiment of the invention, the distribution condition of the stream resources of the live broadcast room client is controlled based on the residual stream resources, the current-limiting operation frequency, the screenshot frequency and the screenshot failure rate of the live broadcast room client, so that the normal operation of the screenshot service is ensured, and the influence on the normal operation of the live broadcast room client is avoided.
In the embodiment of the invention, because the screenshot service of the live broadcast room is essentially different from the traditional mobile phone screenshot service operation, the screenshot service of the live broadcast room is that the server sends the image resource corresponding to the area to the client according to the screenshot area of the client so as to finish screenshot, the screenshot service of the live broadcast room occupies the stream resource of the client of the live broadcast room, and further the server further distributes the stream resource to the client of the live broadcast room so as to facilitate the normal work of the client of the live broadcast room, thereby finally bringing a certain burden to the work of the server,
therefore, in the embodiment of the present invention, in step S1, the remaining stream resources, the current limiting operation frequency, the screenshot frequency, and the screenshot failure rate of the live broadcast room client are monitored, and when the conditions allow, real-time monitoring is performed, so as to know the stream resource usage of the live broadcast room client and facilitate later adjustment;
in actual monitoring, a monitoring method based on a token bucket algorithm is provided, namely, the token bucket algorithm is used for monitoring the residual stream resources, the current-limiting operation frequency, the screenshot frequency and the screenshot failure rate of the client side of the live broadcast room, and the method specifically comprises the following steps:
a1, initializing token bucket size to S0Setting the size of a token bucket at the moment t as S (t), wherein the capacity of the token bucket represents the storage space of the stream resources of the client, and the token of the token bucket represents the stream resources of the client;
a2, initially setting P to be put into token bucket per second0The number of tokens put into the token bucket per second at the moment t is P (t);
a3, monitoring the number of the remaining tokens in the token bucket, and recording as R (t);
a4, when the number of tokens in the token bucket is zero, performing current limiting operation, and recording the current limiting times at t moment as I (t);
a5, recording the loss frequency of the pull loss per second at the time t, and recording the loss frequency as F (t);
the token bucket algorithm is an existing algorithm, and has certain reliability for monitoring the residual stream resources, the current-limiting operation frequency, the screenshot frequency and the screenshot failure rate of the client side of the live broadcast room;
it should be noted that P is put into the token bucket every second0A token representing the amount of streaming resources allocated to the live broadcast room client per second;
in addition, the current limiting operation is specifically that the remaining stream resources of the live broadcast room client are zero, that is, the number of tokens in the token bucket is 0, and the subsequent operation requiring the use of the remaining stream resources is directly performed with a return operation.
It should be noted that the token bucket algorithm is one of the most commonly used algorithms in network Traffic Shaping (Traffic Shaping) and Rate Limiting (Rate Limiting);
typically, token bucket algorithms are used to control the amount of data sent onto the network and to allow the transmission of bursts of data.
In step S2, in the embodiment of the present invention, when the remaining streaming resource is greater than the preset resource remaining threshold or the screenshot failure rate is greater than the preset first failure threshold, the total amount of the remaining streaming resource is reduced and the subsequent resources allocated to the remaining streaming resource are reduced,
if the residual stream resources are greater than the preset resource residual threshold, it is indicated that the amount of the residual stream resources of the live broadcast room client is enough to maintain the normal operation of the live broadcast room client, and even exceeds the requirement of normal work, so that in order to save the amount of the stream resources, the total amount of the resources of the residual stream resources can be properly reduced, and the resources subsequently allocated to the residual stream resources can be reduced;
when the screenshot failure rate is greater than the preset first failure threshold, the network environment of the client of the live broadcast room is possibly poor, so that stream resources are added and allocated to the client, resource waste is substantially caused, and the pressure of the server is increased, so that the total amount of the resources of the residual stream resources is also properly reduced, and the resources subsequently allocated to the residual stream resources are also reduced;
in an embodiment of the present invention, in response to the monitoring method based on the token bucket algorithm, when time t, r (t) is greater than the resource remaining threshold, S (t +1) ═ S (t) -r (t)/2 and P (t +1) ═ P (t) -r (t) (/ 2);
s (t +1) is the size of the token bucket at the moment of t +1, and P (t +1) is the number of tokens put into the token bucket per second at the moment of t + 1;
when f (t) is greater than the first failure threshold at time t, let S (t +1) be S (t)/2 and P (t +1) be P (t)/2;
s (t +1) is the size of the token bucket at the moment t +1, and P (t +1) is the number of tokens put into the token bucket per second at the moment t + 1.
Further in step S3, when the current limiting operation frequency is greater than the preset current limiting frequency threshold and the screenshot failure rate is less than the preset second failure threshold, increasing the total amount of resources of the remaining stream resources and increasing subsequent resources allocated to the remaining stream resources;
when the current limiting operation is frequent and the current limiting operation frequency is high, it is symbolized that the screenshot operation is not failed due to a network problem at the moment, but the total amount of the resources of the residual stream resources is increased, the resources subsequently distributed to the residual stream resources are increased, the number of the stream resources of the client side in the live broadcast room is increased, and the smooth operation of the client side is ensured;
in an embodiment of the present invention, in response to the monitoring method based on the token bucket algorithm, when time t, assuming that i (t) is greater than the current limit frequency threshold and f (t) is less than the second failure threshold, S (t +1) ═ S (t) + i (t) and P (t +1) ═ S (t) + i (t);
s (t +1) is the size of the token bucket at the moment t +1, and I (t +1) is the current limiting times at the moment t + 1.
Based on the same inventive concept, the application provides an embodiment of a regulation and control system for screenshot service corresponding to the first embodiment, which is detailed in the second embodiment
Example two
As shown in fig. 3, a second embodiment of the present invention provides a regulation and control system for screenshot service, which includes:
a live broadcast client monitoring unit 1, configured to monitor remaining stream resources, a current limiting operation frequency, a screenshot frequency, and a screenshot failure rate of a live broadcast room client;
the first regulating and controlling unit 2 is configured to reduce the total amount of resources of the remaining stream resources and reduce resources subsequently allocated to the remaining stream resources when the remaining stream resources are greater than a preset resource remaining threshold or a screenshot failure rate is greater than a preset first failure threshold;
and the second regulating and controlling unit 3 is configured to increase the total amount of resources of the remaining stream resources and increase resources subsequently allocated to the remaining stream resources when the current limiting operation frequency is greater than the preset current limiting frequency threshold and the screen capture failure rate is less than the preset second failure threshold.
In the embodiment of the invention, the distribution condition of the stream resources of the live broadcast room client is controlled based on the residual stream resources, the current-limiting operation frequency, the screenshot frequency and the screenshot failure rate of the live broadcast room client, so that the normal operation of the screenshot service is ensured, and the influence on the normal operation of the live broadcast room client is avoided.
The stream resource is a resource in the form of a data stream that is allocated by the server to the client for data transmission.
In the embodiment of the invention, because the live broadcast screenshot service is essentially different from the traditional mobile phone screenshot service operation, the live broadcast screenshot service is to send the image resource corresponding to the area to the client by the server according to the area of the client screenshot so as to complete screenshot, the live broadcast screenshot service occupies the stream resource of the live broadcast client, and further enables the server to further distribute the stream resource to the live broadcast client so as to facilitate the normal work of the live broadcast client, and finally brings a certain burden to the work of the server.
Therefore, in the embodiment of the invention, when the live broadcast client monitoring unit 1 works, the residual stream resources, the current-limiting operation frequency, the screenshot frequency and the screenshot failure rate of the live broadcast client are monitored, and when the conditions allow, the real-time monitoring is carried out, so that the use condition of the stream resources of the live broadcast client can be known, and the adjustment in the later period is facilitated;
when the live broadcast client monitoring unit 1 actually monitors, a monitoring method based on a token bucket algorithm is used, namely, the token bucket algorithm is used for monitoring the residual stream resources, the current-limiting operation frequency, the screenshot frequency and the screenshot failure rate of the live broadcast client, and the method specifically comprises the following steps:
a1, initializing token bucket size to S0Setting the size of a token bucket at the moment t as S (t), wherein the capacity of the token bucket represents the storage space of the stream resources of the client, and the token of the token bucket represents the stream resources of the client;
a2, initially setting P to be put into token bucket per second0The number of tokens put into the token bucket per second at the moment t is P (t);
a3, monitoring the number of the remaining tokens in the token bucket, and recording as R (t);
a4, when the number of tokens in the token bucket is zero, performing current limiting operation, and recording the current limiting times at t moment as I (t);
a5, recording the loss frequency of the pull loss per second at the time t, and recording the loss frequency as F (t);
the token bucket algorithm is an existing algorithm, and has certain reliability for monitoring the residual stream resources, the current-limiting operation frequency, the screenshot frequency and the screenshot failure rate of the client side of the live broadcast room;
it should be noted that P is put into the token bucket every second0And a token indicating the amount of streaming resources allocated to the live-air client per second.
In the embodiment of the invention, when the first regulation and control unit 2 works and the residual flow resource is larger than the preset resource residual threshold or the screenshot failure rate is larger than the preset first failure threshold, the total resource amount of the residual flow resource is reduced and the subsequent resource distributed to the residual flow resource is reduced,
if the residual stream resources are greater than the preset resource residual threshold, it is indicated that the amount of the residual stream resources of the live broadcast room client is enough to maintain the normal operation of the live broadcast room client, and even exceeds the requirement of normal work, so that in order to save the amount of the stream resources, the total amount of the resources of the residual stream resources can be properly reduced, and the resources subsequently allocated to the residual stream resources can be reduced;
when the screenshot failure rate is greater than the preset first failure threshold, the network environment of the client of the live broadcast room is possibly poor, so that stream resources are added and allocated to the client, resource waste is substantially caused, and the pressure of the server is increased, so that the total amount of the resources of the residual stream resources is also properly reduced, and the resources subsequently allocated to the residual stream resources are also reduced;
in an embodiment of the present invention, the first control unit 2 corresponds to the monitoring method based on the token bucket algorithm, and when time t, r (t) is greater than the resource remaining threshold, the first control unit makes S (t +1) equal to S (t) -r (t)/2 and P (t +1) equal to P (t) -r (t)/2;
s (t +1) is the size of the token bucket at the moment of t +1, and P (t +1) is the number of tokens put into the token bucket per second at the moment of t + 1;
when f (t) is greater than the first failure threshold at time t, let S (t +1) be S (t)/2 and P (t +1) be P (t)/2;
s (t +1) is the size of the token bucket at the moment t +1, and P (t +1) is the number of tokens put into the token bucket per second at the moment t + 1.
When the second regulation and control unit 3 works, when the current-limiting operation frequency is greater than the preset current-limiting frequency threshold and the screenshot failure rate is less than the preset second failure threshold, the total amount of resources of the remaining stream resources is increased and the resources subsequently allocated to the remaining stream resources are increased;
when the current limiting operation is frequent and the current limiting operation frequency is high, it is symbolized that the screenshot operation is not failed due to a network problem at the moment, but the total amount of the resources of the residual stream resources is increased, the resources subsequently distributed to the residual stream resources are increased, the number of the stream resources of the client side in the live broadcast room is increased, and the smooth operation of the client side is ensured;
in an embodiment of the present invention, the second control unit 3 corresponds to the monitoring method based on the token bucket algorithm, and when the time t is, assuming that i (t) is greater than the current limit frequency threshold and f (t) is less than the second failure threshold, let S (t +1) ═ S (t) + i (t) and P (t +1) ═ S (t) + i (t);
