The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Some embodiments of the invention are described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.
In the prior art, when the access pressure of a streaming media server cluster is reduced, in order to reduce resource waste, the streaming media server cluster often needs to be reduced, that is, part of streaming media servers in the streaming media server cluster are recovered, so that the updated streaming media server cluster can not only ensure the access requirements of users, but also ensure reasonable resource allocation. In view of the above, embodiments of the present invention provide a method for managing a streaming media server cluster, so as to alleviate the technical problems mentioned above.
Example one
Fig. 1 is a flowchart of a method for managing a streaming media server cluster according to an embodiment of the present invention, and as shown in fig. 1, the method specifically includes the following steps:
step S102, acquiring the number of pushed streams of each streaming media server in the streaming media server cluster to be managed at the current moment and the number of connections of the streaming media server cluster to be managed at a plurality of moments in each preset time period in a preset historical period.
Specifically, in the embodiment of the present invention, each streaming media server in a streaming media server cluster is installed with one acquisition program, and all the acquisition programs are connected to a central server, and the acquisition program can acquire parameters such as the connection number of the streaming media server where the acquisition program is located and hardware data (CPU, memory, bandwidth, hard disk usage rate, etc.) in real time, where the connection number represents the sum of the push stream number and the pull stream number, the push stream number refers to the total number of anchor broadcasts on line, and the pull stream number refers to the total number of viewers on line.
When a streaming media server cluster to be managed is managed, the embodiment of the invention specifically studies how to reduce the capacity of the streaming media server cluster, and at the beginning of the operation of the method, a central server first acquires the number of pushed streams of each streaming media server in the streaming media server cluster to be managed at the current moment and the number of connections of the streaming media server cluster to be managed at a plurality of moments in each preset time period in a preset historical period, wherein the starting moment of the preset time period is the same moment as the current moment.
For convenience of understanding, in the following description, assume that the current time is 9:25am, the preset history period is 3 days, the preset time duration is 30 minutes (9:25am-9:55am), and the streaming server cluster includes 5 streaming servers, which are respectively: a1, a2, A3, a4, a 5.
To determine whether the streaming media server cluster needs to be scaled, on one hand, the number of streams pushed by the streaming media servers a1-a5 at the current time is (30, 60, 10, 5, 80), and on the other hand, the number of connections at several times within 9:25am-9:55am per day in the previous 3 days (yesterday, the previous day, the most previous day) of the streaming media server cluster to be managed a1-a5 is obtained, for example, the number of connections at 5 times of 9:29am, 9:34am, 9:40am, 9:50am, 9:55am are acquired, for example, yesterday shows that the number of connections at the 5 times is (6000, 9000, 10000, 150000, 17000), the number of connections at the 5 times of the day before is (8000, 9000, 11000, 130000, 13500), and the number of connections at the 5 times of the day before is (10000, 9000, 9500, 8000, 7000).
The embodiment of the invention does not specifically limit the duration of the preset history period and the duration of the preset time period, and the user can select the preset history period according to actual requirements, generally, the preset history period selects the days which are the closest to the current date.
Step S104, determining whether the current time carries out capacity reduction on the streaming media server cluster to be managed based on the connection number of the streaming media server cluster to be managed at a plurality of times in each preset time period in the preset historical period.
After the connection number at a plurality of times in each preset time period in the preset history period is obtained, the connection number in the historical preset time period is used as a reference to further determine whether to reduce the capacity of the streaming media server cluster, for example, whether to reduce the capacity of the streaming media server cluster at the current time may be determined by referring to the development trend of the connection number of the streaming media server cluster.
Step S106, if the capacity reduction is determined, the capacity reduction server is determined based on the number of pushed streams of each streaming media server at the current moment, the preset threshold value of the number of pushed streams and the preset capacity reduction threshold value, and an updated streaming media server cluster is constructed based on the remaining streaming media servers.
If the streaming media server cluster is determined to be subjected to capacity reduction, the capacity reduction server is determined according to the number of pushed streams of each streaming media server at the current moment, a preset threshold of the number of pushed streams and a preset threshold of the capacity reduction, the capacity reduction server refers to the streaming media server to be recovered, the capacity reduction server may be one or more, the preset threshold of the pushed streams is a threshold used for judging whether the number of pushed streams of the streaming media server is too low, the preset threshold of the capacity reduction is a limit used for limiting the number of the streaming media servers recovered at a time, after the capacity reduction server is determined, the remaining streaming media servers are integrated, and an updated streaming media server cluster is constructed.
In the prior art, when a streaming media server cluster is subjected to capacity reduction, staff often need to select a recycled streaming media server according to experience, so that too much manual intervention is required, autonomous decision cannot be made, and decision errors are prone to occur. Compared with the prior art, the invention provides a management method of a streaming media server cluster, which comprises the steps of firstly obtaining the number of pushed streams of each streaming media server in the streaming media server cluster to be managed at the current moment and the connection number of the streaming media server cluster to be managed at a plurality of moments in each preset time period in a preset historical period; then, whether the streaming media server cluster to be managed needs to be subjected to capacity reduction is autonomously determined according to the connection number; and if the capacity reduction is determined, determining a capacity reduction server according to the number of pushed streams at the current moment, a preset pushed stream number threshold value and a preset capacity reduction threshold value, and constructing an updated streaming media server cluster based on the rest streaming media servers. The method can realize the complete autonomous decision of the capacity reduction of the streaming media server cluster, the capacity reduction decision is more reasonable, and the technical problems that the autonomous decision cannot be realized and the decision error is easy to occur in the server cluster management method in the prior art are effectively solved.
The above briefly describes the management method of the streaming media server cluster provided in the embodiment of the present invention, and details how to determine whether to perform a capacity reduction on the streaming media server cluster to be managed at the current time are described below.
In an optional implementation manner, as shown in fig. 2, in the step S104, determining whether to reduce the capacity of the streaming media server cluster to be managed at the current time based on the number of connections of the streaming media server cluster to be managed at a plurality of times in each preset time period in the preset history cycle, specifically includes the following steps:
step S1041, determining a connection number development trend of each preset time period in the preset history period based on the connection numbers of the streaming media server cluster to be managed at a plurality of times in each preset time period in the preset history period.
Specifically, after the connection number of the streaming media server cluster to be managed at a plurality of moments in each preset time period in the preset history cycle is obtained, the connection number development trend of each preset time period in the preset history cycle is determined according to the connection numbers, wherein the development trend includes any one of the following trends: ascending and descending.
By using the above example, the connection numbers of 5 moments in the preset time period of yesterday are respectively (6000, 9000, 10000, 150000, 17000), the connection numbers of 5 moments in the preset time period of the previous day are respectively (8000, 9000, 11000, 130000, 13500), and the connection numbers of 5 moments in the preset time period of the previous day are respectively (10000, 9000, 9500, 8000, 7000), the connection number development trend of each preset time period is identified by using some existing algorithm models or other technical means, and according to the above data, the connection numbers in the preset time period of yesterday are in an ascending trend, the connection numbers in the preset time period of the previous day are also in an ascending trend, and the connection numbers in the preset time period of the previous day are in a descending trend.
Step S1042, determining whether to reduce the volume of the streaming media server cluster to be managed at the current time based on the connection number development trend of all the preset time periods.
After the development trend of the number of connections in each preset time period in the preset history period is determined, whether the streaming media server cluster needs to be reduced or not is determined according to the development trend.
In an optional implementation manner, in the step S1042, it is determined whether to reduce the capacity of the streaming media server cluster to be managed at the current time based on the connection number development trend of all preset time periods, where the method specifically includes the following steps:
and if the number of the preset time periods with the development trend of descending in the preset historical period reaches a preset threshold value, determining that the streaming media server cluster to be managed needs to be subjected to capacity reduction.
And if the number of the preset time periods with the descending development trend in the preset historical period does not reach the preset threshold value, determining that the capacity reduction of the streaming media server cluster to be managed is not needed.
In the example provided above, when the preset history period is 3 days, the number of connections for 2 days is in an upward trend, and the number of connections for 1 day is in a downward trend. If the preset threshold is set to be 2, the number of the preset time periods with the descending development trend in the preset historical period is not equal to the preset threshold, and the streaming media server cluster to be managed does not need to be subjected to capacity reduction; however, if the preset threshold is set to 1, the number of the preset time periods in which the development trend in the preset history period is decreased reaches the preset threshold, and the streaming media server cluster to be managed needs to be reduced. Optionally, the number of the preset time periods in the preset history period is an odd number, and if the odd number is N, the preset threshold value may be set to (N +1)/2, so that when the trend of the connection number is more than half of the descending trend, it may be determined that the streaming media server cluster needs to be reduced.
In the above, a detailed description is given to how to determine whether to perform a capacity reduction on the streaming media server cluster to be managed at the current time, and a description is given below of how to select a capacity reduction server after determining the capacity reduction.
In an optional implementation manner, as shown in fig. 3, in the step S106, determining a capacity reduction server based on the number of pushed streams of each streaming media server at the current time, a preset threshold of the number of pushed streams, and a preset capacity reduction threshold specifically includes the following steps:
step S1061, comparing the number of stream pushes of each streaming media server at the current time with a preset threshold of the number of stream pushes, and determining a target streaming media server set based on the comparison result.
Specifically, after it is determined that the streaming media server cluster needs to be subjected to capacity reduction, the number of pushed streams of each streaming media server at the current time is first compared with a preset pushed stream threshold, and a target streaming media server set is determined according to all comparison results, where the preset pushed stream threshold is described above as a threshold used for determining whether the number of pushed streams of the streaming media server is too low, and in the embodiment of the present invention, the number of pushed streams of all streaming media servers in the target streaming media server set is smaller than the preset pushed stream number.
By way of example above, the number of streams pushed by the streaming media servers at the current time point a1-a5 is (30, 60, 10, 5, 80), and if the preset threshold of the number of streams is 40, the number of streaming media servers in the target set of streaming media servers is 3.
Step S1062, determining whether the number of the streaming media servers in the target streaming media server set is greater than a preset capacity reduction threshold.
If yes, go to step S1063, and if no, go to step S1064.
Step S1063, randomly selecting a target number of streaming media servers from the target streaming media server set as capacity reduction servers, where the target number is equal to a preset capacity reduction threshold.
Step S1064, using all the streaming media servers in the target streaming media server set as the capacity reduction servers.
In order to avoid that the number of the single recovery servers affects parameters such as server response time too much, a preset capacity reduction threshold is introduced when the capacity reduction number is determined, which has been described above, where the preset capacity reduction threshold is a limit value used for limiting the number of the single recovery streaming media servers, and if the preset capacity reduction threshold is 2, it is described that the single capacity reduction allows recovery of 2 streaming media servers at most, in the above example, the number of the streaming media servers in the target streaming media server set is 3, that is, the number of the streaming media servers to be recovered is proposed to be 3, but since 3>2 (the preset capacity reduction threshold), it is determined that the capacity reduction operation at the current time can only recover 2 streaming media servers, and 2 streaming media servers can be randomly selected from the target streaming media server set as the capacity reduction servers; if the preset capacity reduction threshold value is 4, it indicates that the single capacity reduction allows to recover 4 streaming media servers at most, and since 4>3, all the streaming media servers in the target streaming media server set can be used as capacity reduction servers to be recovered.
After determining that the streaming media server cluster to be managed is subjected to capacity reduction and selecting a capacity reduction server, in order to ensure that the capacity reduction operation does not affect the user experience, in an optional implementation manner, the method further includes the following steps:
and after the capacity reduction server is determined, when the number of pushed streams of the capacity reduction server is 0, the capacity reduction server is recovered, and after the capacity reduction server is determined, if the streaming media server cluster to be managed receives a new connection request, the new connection request is distributed to the streaming media server in the updated streaming media server cluster.
That is, even though it is determined at the current moment that the a4 streaming server is to be reclaimed, it is necessary to wait until all the online anchor of the a4 server is offline (the number of push streams is 0) before the operation of the streaming server reclamation is performed, and if it is determined that a4 is to be reclaimed, the streaming server cluster distributes a new anchor connection request to the remaining streaming servers after receiving the new connection request by the central server.
By using the scheme provided by the embodiment of the invention, the complete autonomous decision of the capacity reduction of the streaming media server cluster can be realized by acquiring the push stream number of each streaming media server in the streaming media server cluster to be managed at the current moment and the connection number of the cluster at a plurality of moments in each preset time period in the preset historical period and processing the data, so that the capacity reduction decision is more reasonable and intelligent without manual intervention, and the technical problems that the autonomous decision cannot be made and the decision error is easy to occur in the server cluster management method in the prior art are effectively solved. The embodiment of the invention mainly describes a management method of a streaming media server cluster, and the method is also suitable for the management of server clusters with state connection and the management of server clusters with state distribution.

Fig. 4 is a functional block diagram of a management apparatus for a streaming media server cluster according to an embodiment of the present invention, and as shown in fig. 4, the apparatus mainly includes: an obtaining module 10, a first determining module 20, a second determining module 30, wherein:

The first determining module 20 is configured to determine whether to reduce the capacity of the streaming media server cluster to be managed at the current time based on the number of connections of the streaming media server cluster to be managed at several times in each preset time period in the preset history cycle.
