Detailed Description
For the purposes of making the objects, technical solutions and advantages of the embodiments of the present disclosure more apparent, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure, and it is apparent that the described embodiments are some embodiments of the present disclosure, but not all embodiments. Based on the embodiments in this disclosure, all other embodiments that a person of ordinary skill in the art would obtain without making any inventive effort are within the scope of protection of this disclosure.
The terms first, second, third and the like in the description and in the claims and in the above-described figures, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the disclosure described herein may be capable of operation in sequences other than those illustrated or described herein.
Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Live broadcasting can be understood as an information network publishing mode with a bidirectional circulation process, wherein information is synchronously produced and published along with the occurrence and development processes of an event on site. The mode of the system can also be divided into live broadcast, studio interview type live broadcast, text and picture live broadcast, video and audio live broadcast or live broadcast with a third party (such as a television) for providing information sources, and the like, and the live broadcast has the functions of mass storage and convenient searching.
The live broadcast server may be understood as a server supporting a live broadcast function, that is, "live broadcast" in the live broadcast server cannot be understood as limiting the server, and the live broadcast server may be a cloud server, a local server, a server cluster, or an electronic device supporting a live broadcast function, which is not limited in this embodiment.
The user may access the live broadcast through the user device. Illustratively, a user may access a live broadcast corresponding to the shared uniform resource locator (Uniform Resource Locator, URL) through a browser, and may access the live broadcast without logging in.
User equipment is understood to be equipment that can establish a communication link with a live server and has a display function, such as a desktop computer, a notebook computer, a mobile phone, etc., which are not listed here.
It can be understood that the types of live broadcast are numerous, such as educational live broadcast, cultural live broadcast, video live broadcast, conference live broadcast, object (may be a physical object or a virtual object) live broadcast, etc., and for some types of live broadcast, in order to ensure the effectiveness of the live broadcast as much as possible, and control the cost of the live broadcast, etc., the number of users accessing the live broadcast needs to be controlled, that is, the number of people watching the live broadcast is controlled.
By taking education live broadcasting as an example, and taking a special delivery classroom in education live broadcasting as an example, a platform for providing live broadcasting can open the special delivery classroom to the public through live broadcasting, so as to avoid defects such as blocking caused by too many people, improve the reliability of watching live broadcasting by each public, avoid too high cost, and control the number of people accessing live broadcasting.
The special class emphasizes the specialization, mainly aims at the problems that education resources are relatively weak and relevant specified courses are not available, are specially give a course on the internet or are used for synchronously teaching, and utilize the Internet to push appropriate high-quality education resources according to teaching progress, so that the fair and balanced development of education is promoted.
In some embodiments, the upper limit value of the number of users watching live broadcast may be set, and the number of users watching live broadcast may be counted, and when the number of users watching live broadcast reaches the upper limit value of the number, the watching request of the users who later request to watch live broadcast is refused.
However, the number of users actually watching live broadcast may be smaller than the upper limit value, for example, a user exits from live broadcast after watching live broadcast for one minute, so that the reliability and accuracy of control over accessing live broadcast are low.
To avoid at least one of the above technical problems, the inventors of the present disclosure have creatively worked to obtain the inventive concept of the present disclosure: the number of users watching the live broadcast is determined from two granularities, namely, coarse granularity and fine granularity, wherein the number of users watching the live broadcast is determined by coarse granularity, namely, the accumulated number of users watching the live broadcast is determined by fine granularity, the number of users watching the live broadcast is determined by fine granularity, namely, the actual number of users currently watching the live broadcast, and the control of accessing the live broadcast is realized through the accumulated number and the actual number.
The technical scheme of the present disclosure is described in detail below through specific embodiments. It should be noted that the following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.
The present disclosure provides a control method for accessing live broadcast, which can be applied to a live broadcast server. Referring to fig. 1, fig. 1 is a flowchart of a control method for accessing live broadcast according to an embodiment of the disclosure, as shown in fig. 1, the method includes:
s101: and receiving an access live broadcast request initiated by a user based on a client of the user equipment.
The live broadcast access request is used for requesting to access the target live broadcast. The target live broadcast is used to characterize a live broadcast that the user wishes to access, i.e. a live broadcast that the user wishes to view, and is not to be interpreted as a definition of the content of the live broadcast.
For example, the execution subject of the present embodiment may be a control device (hereinafter simply referred to as a control device) for accessing live broadcast, and the control device may be a processor or a chip or the like provided in a live broadcast server.
The present embodiment is not limited as to the manner in which the control device obtains the access live request. For example, the user may initiate the access live broadcast request by means of voice, and correspondingly, the control device obtains the voice initiated by the user through the client of the user device, so as to obtain the access live broadcast request. For another example, the user may initiate a live access request in a touch manner, and correspondingly, the control device obtains the live access request.
Taking the example that a user can initiate a request for accessing live broadcast in a voice manner, the following is exemplarily set forth: the user equipment is provided with a pickup assembly, the pickup assembly establishes a communication link with the client, and the pickup assembly collects a live broadcast access request initiated by user voice and transmits the live broadcast access request to the control device.
S102: and acquiring the number of users of the accumulated access target live broadcast to obtain a first access number.
By way of example, the first access number may be understood as the number of users accessing the target live broadcast that are accumulated from the beginning of the target live broadcast to the current moment. If the target live broadcast has been broadcast for 10 minutes to the current time, the first access number is the number of all users accessing the target live broadcast within 10 minutes.
S103: if the first access number is greater than or equal to a preset first threshold, acquiring the number of users currently accessing the target live broadcast, and acquiring a second access number.
It is understood that the first threshold is an upper limit value of the number of users accessing the target live broadcast, i.e. a threshold value in terms of the total number of users accessing the target live broadcast. The magnitude of the first threshold may be determined based on demand, history, experimentation, and the like. If a live scene with more users can be supported for a live server, the first threshold value can be relatively larger; conversely, the first threshold may be relatively small for live scenes where the live server may support fewer users.
The second access number and the first access number are relative concepts, the second access number is the number of users accessing the target live broadcast at the current moment, and the users accessing the live broadcast at the current moment can be determined based on a heartbeat request initiated by the client to the live broadcast server.
For example, in a preset heartbeat frequency range, if the live broadcast server receives a heartbeat request initiated by a certain client, the client is indicated to be the client accessing the target live broadcast at the current moment; otherwise, if a certain client does not initiate a heartbeat request to the live broadcast server within the heartbeat frequency range, the user corresponding to the client is indicated to have exited the access to the target live broadcast.
In combination with the above analysis, the first access number is the number of users accessing the target live broadcast after the target live broadcast, for example, the first access number includes the number of users accessing the target live broadcast at the current time (i.e., the second access number), and the first access number includes the number of users accessing the target live broadcast before and not accessing the target live broadcast at the current time.
That is, the first access number may be understood as the number of users of the access target live broadcast determined from the coarse granularity, i.e., the number determined from the overall granularity of the access target live broadcast. The second access number may be understood as the number of users accessing the target live broadcast determined from the fine granularity, i.e. the number determined from the local granularity of accessing the target live broadcast at the current moment.
The user accessing the target live broadcast at the current moment can be understood as an effective user, and the user accessing the target live broadcast before and not accessing the target live broadcast at the current moment can be understood as an ineffective user.
Accordingly, the first number of accesses = number of active users + number of inactive users, and the second number of accesses = number of active users. Thus, the first access number=the second access number+the number of dead users.
S104: and if the second access number is smaller than the first threshold, outputting the target live broadcast through the client.
The second access number is smaller than the first threshold, which indicates that the number of users currently accessing the target live broadcast (i.e. the number of effective users) does not exceed the upper limit value of the number of users for which the live broadcast server can view the target live broadcast, so that the control device can output the target live broadcast to the client, so that the user can view the target live broadcast through the user equipment.
Based on the above analysis, the present disclosure provides a control method for accessing live broadcast, where the method may be applied to a live broadcast server, and the method includes: receiving an access live broadcast request initiated by a user based on a client of user equipment, wherein the access live broadcast request is used for requesting to access a target live broadcast, acquiring the user quantity of accumulated access target live broadcast, obtaining a first access quantity, acquiring the user quantity of the current access target live broadcast if the first access quantity is larger than or equal to a preset first threshold value, obtaining a second access quantity, and outputting the target live broadcast through the client if the second access quantity is smaller than the first threshold value.
In order to make the reader more deeply understand the implementation principle of the present disclosure, a control method for accessing live broadcast of the present disclosure will be described in more detail with reference to fig. 2, and the method may be applied to a live broadcast server. As shown in fig. 2, the method includes:
s201: and receiving an access live broadcast request initiated by a user based on a client of the user equipment.
The live broadcast access request is used for requesting to access the target live broadcast.
It will be appreciated that, in order to avoid cumbersome descriptions, the technical features of the present embodiment that are the same as those of the above embodiment are not repeated.
S202: and obtaining token records stored by the live broadcast server, determining the number of users accessing the target live broadcast according to the token records, and obtaining the first access number.
Wherein one token represents one user, i.e. one user corresponds to one token. The method includes that a token is carried in an access live broadcast request initiated by a client so that a control device can carry out authentication processing on access rights of a user based on the token, if the authentication is passed, whether the token is included in a token record or not is determined, if the token is included in the token record, the fact that the user has proposed access to a target live broadcast due to network abnormality or the like is indicated, and the token is not required to be added in the token record; otherwise, if the token record does not include the token, the user is a new user living broadcast of the access target, the token record added with the token is added, and the count value corresponding to the token record is added with 1 so as to determine the first access amount through the count value.
S203: whether the first access number is greater than or equal to a first threshold is determined, if so, S204 is executed, and if not, S206 is executed.
S204: and acquiring the number of users currently accessing the target live broadcast to obtain a second access number.
In some embodiments, the token record is information of the user accessing the target live broadcast that is saved in the form of a snapshot in the disk of the live server. A user accessing the target live broadcast corresponds to a token that is recorded as maintained based on a structured data storage system hash (tairHash) data structure.
Illustratively, the Redis is an in-memory database of the live server, where the in-memory database is to store the content in the database of the live server in the in-memory of the live server. In contrast, the memory database has much faster read-write efficiency than the conventional database (the memory has much higher read-write efficiency than the hard disk).
In order to avoid the defect that the data in the memory database is lost completely due to the power failure or downtime of the live server, in this embodiment, a persistence (RDB) mode is adopted to write the data snapshot in the memory into the disk of the live server, and if the data needs to be recovered, the snapshot file can be read into the memory.
The data structure of the token record is tairHash data structures. For example, the tairHash data structure is a key-value pair (key-value) structure, one key corresponds to one live broadcast, and the live broadcast server can support to play a plurality of live broadcasts simultaneously, wherein the plurality of live broadcasts comprise target live broadcasts, the value corresponding to the key is fieldtoken, and the token number of the current access live broadcast is represented.
In some embodiments, the number of fieldtoken per key, i.e., the number of currently accessed users on a direct broadcast, may be determined by a count statistics method (exhlenWithNoExp). For example, the number of fieldtoken under the key of the target live broadcast is determined through a counting statistical method, so that the second access number is obtained.
In this embodiment, the second access number is determined by combining tairHash data structures and a counting statistical method, so that the concurrence can be greatly improved, that is, in a scene where a plurality of live broadcasts are broadcast by a live broadcast server, the current access number corresponding to each live broadcast is determined in parallel.
In some embodiments, it is also possible to implement that only one thread can determine the current number of accesses at a time through atomic operation (atomic operation). For example, atomic writing of keys may be accomplished by SETNX commands, thereby enabling only one thread to determine the current number of accesses at a time.
In connection with the above analysis, the number of users in the token log may be counted from both a "coarse" and a "fine" granularity. For example, coarse granularity may be understood as: and if the live broadcast access request is that the user accesses the target live broadcast for the first time, adding 1 to the number of the users accessing the target live broadcast. Fine particle size can be understood as: and determining the number of users currently accessing the target live broadcast in combination with the heartbeat request.
In some embodiments, the token has a type attribute including a valid type and an invalid type, the first number of accesses being a total number of tokens in the token record; the second number of accesses is the number of tokens of the valid type in the token record. For a client corresponding to any token, if a heartbeat request initiated by the client within a preset period is received, the type attribute of the token corresponding to the client is an effective type.
If the client initiates a heartbeat request to the control device within a preset period, a user accessing the target live broadcast through the client is an effective user, and correspondingly, a token corresponding to the client is an effective type token, and the user is a user currently accessing the target live broadcast.
Otherwise, if the client does not initiate a heartbeat request to the control device within the preset period, the communication link between the client and the live broadcast server may be disconnected due to network abnormality or user exit operation, etc., the user accessing the target live broadcast through the client is an invalid user, and correspondingly, the token corresponding to the client is an invalid type token, and the user is not the user currently accessing the target live broadcast, but is one user of the number of users accumulating to access the target live broadcast.
That is, the token record has an accumulated number, which is the number of users (i.e., the first access number) who only increase and decrease for all access targets living broadcast, and a current number, which is the number of users (the second access number) who keep heartbeats with the living broadcast server.
S205: whether the second access number is smaller than the first threshold is determined, if yes, S206 is executed, and if no, S207 is executed.
S206: and outputting the target live broadcast through the client.
S207: and outputting a prompt message through the client.
The prompt message is used for prompting that the user cannot access the target live broadcast currently.
If the second access number is greater than the first threshold, the number of users accessing the target live broadcast at present is not up to the upper limit value of the number, and the users can be prompted that the target live broadcast cannot be accessed at present. Or the prompt message may also prompt the user "retry later" or the like.
That is, whether to output the target live broadcast to the client may be determined based on the first access number, and if the first access number is smaller than the first threshold, it is indicated that the number of users that access the target live broadcast cumulatively has not reached the number upper limit, and the control device may output the target live broadcast to the client, so that the user views the target live broadcast through the user device. And the subsequent operation of acquiring the second access quantity and the like is not needed, so that the response efficiency and the overall access performance of the live broadcast server are improved.
If the first access is greater than or equal to the first threshold, the number of users accumulating the access target live broadcast is indicated to reach the upper limit value of the number, and in order to realize the reliability of the control of the access target live broadcast and avoid the excessive number of the people accessing the target live broadcast, the control device can acquire the second access number.
And if the acquired second access number is smaller than the first threshold, the control device can output the target live broadcast to the client so that the user can watch the target live broadcast through the user equipment. Otherwise, if the second access number is greater than or equal to the first threshold, which indicates that the number of users currently accessing the target live broadcast has reached the upper limit value of the number, the control device does not output the target live broadcast to the client, but may output the prompting message as described in the foregoing embodiment.
In order to make the first access quantity as large as possible be the number of users currently accessing the target live broadcast, so as to process as many access live broadcast requests as possible in a coarse granularity stage without entering a fine granularity stage, thereby improving the efficiency of accessing live broadcast and improving the experience of users accessing live broadcast, when the first access quantity is greater than or equal to a first threshold value, the first access quantity can be adjusted to be the same as the second access quantity.
On this basis, the first number of accesses may be further optimized, for example, the first number of accesses may be adjusted to the same value as the second number of accesses on a time-interval basis. Similarly, the time interval may be determined based on demand, history, and experimentation.
For example, if the first access amount is greater than or equal to the first threshold, the first access amount may be adjusted to the same value as the second access amount at 60 seconds intervals.
Alternatively, the first access number may be adjusted to the same value as the second access number when the first access number is greater than the second threshold. Wherein the second threshold is greater than or equal to the first threshold.
It should be understood that the above examples are only for exemplary purposes of illustrating the possible ways of optimizing the adjustment of the first number of accesses and are not to be construed as limiting the adjustment of the first number of accesses.
In connection with the above analysis, the second number of accesses is the number of active users, which may be determined based on the heartbeat request. In some embodiments, the client may initiate a heartbeat request to the live server based on a fixed frequency, and if the live server does not receive the heartbeat request initiated by the client in the fixed frequency, the user corresponding to the client is indicated as a failure user; otherwise, if the live broadcast server receives the heartbeat request initiated by the client in the fixed frequency, the user corresponding to the client is indicated to be an effective user.
However, particularly for a scenario where the number of users accessing the target live is high, in order to reduce the amount of concurrent access per unit time of the client, in other embodiments, the client may initiate heartbeat requests to the live server based on a flexible frequency. In order to enable readers to understand deeply the implementation principle of the control method for accessing live broadcast under the condition that the client initiates the heartbeat request to the live broadcast server based on flexible frequency, the implementation principle is described in detail with reference to fig. 3.
Fig. 3 is a schematic diagram of a control method for accessing live broadcast according to another embodiment of the present disclosure, where the method may be applied to a live broadcast server, as shown in fig. 3, and the method includes:
S301: the client initiates a request for accessing the live broadcast to the live broadcast server. The live broadcast access request is used for requesting to access the target live broadcast.
Illustratively, the user is based on a request to access live initiated by a client of the user device. Correspondingly, a live broadcast access request initiated by a user based on a client of user equipment is received.
Similarly, in order to avoid cumbersome descriptions, the technical features of the present embodiment that are the same as those of the above embodiment are not repeated.
S302: and the live broadcast server acquires the number of users which access the target live broadcast in a cumulative way, and obtains the first access number.
S303: if the first access number is greater than or equal to a preset first threshold, the live broadcast server acquires the number of users currently accessing the target live broadcast to obtain a second access number.
S304: and if the second access number is smaller than the first threshold value, the live broadcast server transmits the target live broadcast to the client.
The live broadcast server transmits the target live broadcast to the user equipment through the client, and the user equipment receives the target live broadcast correspondingly.
S305: and the client outputs the target live broadcast.
And if the client plays the target live broadcast through the display screen of the user equipment, the user can watch the target live broadcast.
S306: the live server determines a target polling interval according to the second number of accesses. The target polling time interval is used for indicating the frequency of the client initiating the heartbeat request to the live server.
S307: the live server sends a target polling interval to the client.
Correspondingly, the client receives the target polling time interval.
S308: the client initiates a heartbeat request to the live server based on the target polling interval.
Accordingly, the live server receives the heartbeat request.
It should be noted that, the second access number may be a dynamically changing number, that is, the number of users currently accessing the target live broadcast may increase or decrease, and the target polling time interval is also a dynamically changing time interval, that is, may change along with the change of the second access number. The target polling interval is relatively small if the second number of accesses increases, and relatively large if the second number of accesses decreases.
In some embodiments, the second number of accesses is inversely proportional to the target polling time interval. The larger the second access number, the shorter the target polling interval; conversely, the smaller the second number of accesses, the longer the target polling interval.
By the scheme provided by the embodiment, under the condition that the access amount of the target live broadcast is larger, the client initiates a heartbeat request to the live broadcast server in a shorter time period so as to release the access resource of the access target live broadcast of the invalid user and meet the access requirement of more access target live broadcast.
In some embodiments, S306 may include the steps of:
A first step of: and determining the current limiting feedback code of the second access quantity according to the second access quantity and the preset access current limiting quantity.
Similarly, the number of access restrictions may be determined based on the requirements, the history, and the test, which is not limited in this embodiment. Preferably, the number of access restrictions may be greater than or equal to the first threshold.
For example, according to the size relationship between the second access number and the access current limit number, different access scenes may be determined, if the second access number is smaller than the access current limit number, the access scene is a normal access scene, if the second access number is greater than or equal to the access current limit number, the access scene is a current limit retry scene, and if the live broadcast server currently receives a greater number of requests for accessing the live broadcast, the access scene is a concurrent retry scene. And the current limiting feedback codes corresponding to different access scenes are different.
And a second step of: and determining a time interval corresponding to the current limiting feedback code according to a preset mapping relation. The mapping relation is used for representing the corresponding relation between the current limiting feedback code and the time interval.
For example, different current-limiting feedback codes correspond to different time intervals, and when a current-limiting feedback code is determined, a time interval having a corresponding relation with the current-limiting feedback code can be determined from the mapping relation.
In combination with the above analysis, the current-limiting feedback codes corresponding to different access scenes are different, and the time intervals corresponding to different current-limiting feedback codes are different, so that the time intervals corresponding to different access scenes are different.
For example, the time interval of the normal access scenario is [ 10 seconds, 50 seconds ], the time interval of the concurrent retry scenario is [ 2 seconds, 8 seconds ], and the time interval of the current limit retry scenario is [ 1 second, 3 seconds ].
And a third step of: and determining and sending a target polling time interval to the client according to the time interval.
The time interval may be determined as the target polling time interval, or a period of time may be randomly selected from the time interval to be determined as the target polling time interval, and the embodiment is not limited.
In this embodiment, the current-limiting feedback code is determined to determine the time interval based on the current-limiting feedback code, so that the target polling time interval is determined according to the time interval, so that the target polling time interval is associated with the access scene, the actual access scene requirement is met, and the accuracy and reliability of determining the target polling time interval are improved.
Based on the analysis, the live broadcast server can support broadcasting a plurality of live broadcasts simultaneously, and the target live broadcasts are included in the plurality of live broadcasts, so that a target polling time interval can be determined in a double-current limiting mode, namely, the target polling time interval can be determined in a mode of 'whole current limiting dimension + local current limiting dimension', and the accuracy and the reliability of determining the target polling time interval are further improved.
Where the overall current limit dimension refers to the dimension of the current limit number of a plurality of live ensembles played out from the live server. The local current limit dimension refers to the dimension of the number of current limits for broadcasting the target live portion from the live server.
For example, the live server may obtain a third access number to access the plurality of live broadcasts; determining a first polling time interval according to the third access quantity and a preset first access current limiting quantity of the live broadcast server; determining a second polling time interval according to the second access quantity and a second access current limiting quantity of the preset target live broadcast; and determining a target polling time interval according to the first polling time interval and the second polling time interval.
Wherein the third access number is the sum of all the user numbers accessing the plurality of live broadcasts. The first access current limiting number is the current limiting number of the whole current limiting dimension, and the second access current limiting number is the current limiting number of the local current limiting dimension. The first number of access restrictions is greater than the second number of access restrictions, which may be greater than or equal to the first threshold.
In some embodiments, after determining the first polling interval and the second polling interval, an intersection between the first polling interval and the second polling interval may be determined and determined as the target polling interval.
In some embodiments, if the live broadcast server receives the live broadcast access request, the total number of the live broadcasts accessed currently may be acquired first, and if the total number is greater than or equal to the first access current limit number, the live broadcast access request may be denied. Otherwise, if the total number is smaller than the first access current limit number, the live broadcast requested by the access live broadcast request can be determined, the total number of the live broadcasts requested by the current access request is determined, if the total number is smaller than the second access current limit number corresponding to the requested live broadcast, the requested live broadcast is output, and otherwise, the request is refused.
