Barrage messages are heavily used in audio/video playing/live broadcasting application software. Generally, a bullet screen message is sent to application software by a server (i.e., a bullet screen server) for transmitting and processing the bullet screen message, and then a bullet screen distributing module having a function of distributing the bullet screen message in the application software distributes the received bullet screen message to each bullet screen receiving module.
When the amount of the bullet screen messages sent by the bullet screen server is very large, the distribution pressure of a single bullet screen distribution module is high, and the problem that the bullet screen messages are not distributed timely or even lost can occur.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
The dynamic bullet screen message distribution method provided by the embodiment can be suitable for bullet screen message distribution in audio and video playing/live broadcast application software in an Android client, and is particularly suitable for cascading bullet screen message distribution when the number of bullet screen messages is large. The method can be executed by a dynamic delivery device of the bullet screen message, the device can be realized in a software and/or hardware mode, and the device can be integrated in equipment provided with audio/video playing/live broadcasting application software based on an Android system, for example, typical user terminal equipment such as a mobile phone, a tablet personal computer or a smart television is provided. The execution main body in the embodiment of the invention is a top-level distribution object, and mainly explains the load balancing process of the top-level distribution object. Referring to fig. 1, the method of the present embodiment specifically includes the following steps:
and S110, acquiring the distribution pressure parameter value corresponding to each secondary distribution object.
The secondary distribution object refers to an instantiation object of a bullet screen distribution class of the next level for performing distribution processing on bullet screen messages. The top-level distribution object is arranged opposite to the secondary distribution object, and is an instantiation object of the bullet screen distribution class of the upper level for performing distribution processing on the bullet screen message. The distribution pressure parameter refers to a parameter capable of characterizing the bullet screen message distribution pressure/load of the secondary distribution object. The dispense pressure parameter value refers to a value of a dispense pressure parameter.
Specifically, to implement load balancing in the bullet screen message distribution process, the top-level distribution object needs to first obtain the distribution pressure parameter values of each secondary distribution object that needs to receive bullet screen messages. In practical application, the process of obtaining the distribution pressure parameter value may be establishing a communication channel between the top-level distribution object and each of the secondary distribution objects, so that each of the secondary distribution objects reports the distribution pressure parameter value thereof or the top-level distribution object reads the distribution pressure parameter value thereof from each of the secondary distribution objects; or, a system communication channel in the Android system, such as a system broadcast channel or a third-party open source event bus EventBus, may be utilized to allow each secondary distribution object to deliver its distribution pressure parameter value to the system communication channel, and the top-level distribution object receives the distribution pressure parameter value of each secondary distribution object from the system communication channel.
Illustratively, the distribution pressure parameter includes at least one of a historical message carrying capacity, a current remaining message carrying rate, a current CPU idle rate, and a current remaining memory capacity. The message carrying capacity refers to the number of bullet screen messages (i.e. bullet screen messages to be distributed) which are stored by the secondary distribution object and are to be distributed to each bullet screen receiving object. The historical message carrying capacity refers to the message carrying capacity of the secondary distribution object in the bullet screen message distribution process before the operation, and may be a maximum value or an average value of the message carrying capacity in a set time period, and is preferably the average value, so as to more reasonably reflect the distribution capacity of the secondary distribution object. The message carrying rate refers to a percentage value of the message carrying capacity of the secondary distribution object to the maximum message carrying capacity (i.e. the total message carrying capacity) that the secondary distribution object can carry. The current remaining message carrying rate refers to a percentage value of the remaining amount of the message carrying capacity of the secondary distribution object at the current moment to the total message carrying amount. The current CPU idle rate refers to the system CPU idle rate of the Android client at the current moment. The current residual memory capacity refers to the residual capacity of the system memory of the Android client at the current moment. The advantage of this arrangement is that the load situation of the secondary distribution object can be reflected from at least one perspective.
And S120, determining the message pressure bearing value of each secondary distribution object according to the distribution pressure parameter value of the secondary distribution object and the parameter weight value of the distribution pressure parameter.
The parameter weight value is a value of a proportion of the distribution pressure parameter when determining the message pressure bearing value, and is a value less than or equal to 1. The message pressure-bearing value is an estimated value of the bullet screen message distribution pressure which can be borne by the secondary distribution object currently, and the larger the value is, the larger the number of bullet screen messages to be distributed which can still be received by the secondary distribution object at the current moment is.
Specifically, after the top-level distribution object obtains the distribution pressure parameter value of the secondary-level distribution object, the sum of products (i.e., the cumulative sum of products) of the distribution pressure parameter value and the corresponding parameter weight value can be calculated, so as to obtain the corresponding message pressure-bearing value. For each secondary distribution object, the top distribution object executes the solving process of the message pressure bearing value, and a plurality of message pressure bearing values of a plurality of secondary distribution objects can be obtained.
Illustratively, when the distribution pressure parameter includes a current remaining message bearer rate, a current CPU idle rate, and a current remaining memory capacity, the parameter weight value includes a bearer rate weight value, a CPU weight value, and a memory weight value; determining the message pressure-bearing value of the secondary distribution object according to the distribution pressure parameter value of the secondary distribution object and the parameter weight value of the distribution pressure parameter comprises: and determining the product cumulative sum as the message pressure-bearing value of the secondary distribution object according to the current residual message load rate and load rate weight value, the current CPU idle rate and CPU weight value, and the current residual memory capacity and memory weight value.
Specifically, the distribution pressure parameters of the secondary distribution object are set to be the current remaining message carrying rate, the current CPU idle rate and the current remaining memory capacity, so as to more accurately, comprehensively and real-timely represent the load condition of the secondary distribution object. The parameter weight values correspond to a load factor weight value, a CPU weight value, and a memory weight value, respectively. In this case, the message bearing value is: the message pressure bearing value is the current residual message bearing rate weight value + the current CPU idle rate CPU weight value + the current residual memory capacity memory weight value. The three types of parameter weight values can be fixed values set empirically in advance, or can be dynamically set according to the actual conditions of the Android client.
Illustratively, when the parameter weight value is a preset fixed value, the load factor weight value, the CPU weight value and the memory weight value are respectively a first preset weight value, a second preset weight value and a third preset weight value.
Specifically, since the current remaining message bearer rate is a parameter value for the secondary distribution object alone, which can most intuitively reflect the load condition of the secondary distribution object, the first preset weight value (bearer rate weight value) may be set to a larger value, such as 1. The current CPU idle rate and the current remaining memory capacity are real-time system information of the entire Android client, and both of them can indirectly reflect the load condition of the secondary distribution object, and in consideration of the difference between the consumption demand of the CPU and the consumption demand of the memory for different bullet screen messages, a second preset weight value (CPU weight value) and a third preset weight value (memory weight value) can be statistically determined according to the consumption demands of a plurality of bullet screen messages, and if both are set to 0.5. Thus, the calculation formula of the message carrying capacity result can be: result ═ 1 × danmuAllow +0.5 × cpuAvai +0.5 × memAvai, where danmuAllow, cpuAvai, and memAvai are the current remaining message carrying rate, current CPU idle rate, and current remaining memory capacity, respectively.
Illustratively, when the parameter weight value is a dynamically set numerical value, the CPU weight value and the memory weight value are determined according to the message type of the bullet screen message.
Specifically, when the parameter weight value is a dynamically set numerical value, the CPU weight value and the memory weight value may be determined according to the message type of the bullet screen message to be distributed each time, and the sum of the CPU weight value and the memory weight value is 1. For example, for a first barrage message, which is a service logic processing barrage-like message, the consumption demand of the first barrage message on the CPU is high, and the consumption demand on the memory is low, the CPU weight value and the memory weight value may be set to 0.8 and 0.2, respectively; for the second barrage message, which is a display processing type barrage message, the consumption demand of the second barrage message on the CPU is low, and the consumption demand on the memory is high, and the CPU weight value and the memory weight value may be set to 0.3 and 0.7, respectively. While the setting of the bearer rate weight value may still maintain an empirically set fixed value. At this time, the calculation formula of the message carrying capacity result may be: result ═ 1 × danmuAllow + x × cpuAvai + (1-x) × memAvai, where x and (1-x) are the CPU weight value and the memory weight value, respectively, and x is 0.8 for the first barrage message; for the second barrage message, x is 0.3. The setting can make the message pressure-bearing value of calculation have bullet screen message pertinence more to select target secondary distribution object more rationally.
S130, determining a target secondary distribution object according to each message pressure bearing value corresponding to each secondary distribution object, and distributing the bullet screen message to the target secondary distribution object.
The target secondary distribution object is a target object to be distributed by the bullet screen message, and is a secondary distribution object obtained after the top distribution object is subjected to load balancing.
Specifically, the top-level distribution object determines a maximum message pressure-bearing value from each message pressure-bearing value, and determines a secondary distribution object corresponding to the maximum message pressure-bearing value as a target secondary distribution object. And then, the top-level distribution object distributes the barrage message to the target secondary distribution object through a direct communication channel established between the top-level distribution object and the target secondary distribution object.
The direct communication channel is pre-established in the following way: a bullet screen distribution protocol public interface image { } containing an interface type of a bullet screen distribution function public void OnMessage (Message) is predefined, and a secondary distribution class inherits the bullet screen distribution protocol. Then, when each secondary distribution object is created, each secondary distribution object is generated by calling the constructor instantiation of the secondary distribution class, and the secondary distribution object is also a protocol distribution object and contains a bullet screen distribution function OnMessage as a callback function. After each secondary distribution object is created, the secondary distribution objects are registered to the top-level distribution object, so that the top-level distribution object holds the reference relationship of each secondary distribution object, and the direct expression communication channel is constructed. Then, the process of distributing the barrage message by the top-level distribution object is as follows: and the top-level distribution object takes the bullet screen message as a function input parameter, calls the bullet screen distribution function in the target secondary distribution object held by the top-level distribution object, and transmits the bullet screen message to the target secondary distribution object. It should be noted that the input parameter Message of the bullet screen distribution function is only an abstract representation, and it can be specifically set according to the data format or application requirement of the bullet screen Message.
Exemplarily, determining the target secondary distribution object according to each message pressure-bearing value corresponding to each secondary distribution object includes: storing the bearing value of each message to a bearing value array according to the storage sequence of each secondary distribution object in the distribution object array; determining a maximum message bearing value and an array index of the maximum message bearing value in a bearing value array according to the bearing value array; and determining a secondary distribution object corresponding to the array index from the distribution object array as a target secondary distribution object. The secondary distribution object and the message bearing value thereof are respectively maintained through the two arrays with the one-to-one correspondence relationship among the elements, and the system memory can be effectively saved.
Exemplarily, determining the target secondary distribution object according to each message pressure-bearing value corresponding to each secondary distribution object includes: for any secondary distribution object, according to the object identifier and the message bearing value of the secondary distribution object, calling an element insertion function put (object identifier, message bearing value) of a bearing value map set, and storing the message bearing value of the secondary distribution object to the bearing value map set; determining the maximum message bearing value according to each bearing value map value in the bearing value map set; taking the maximum message bearing value as a function input parameter, calling a key acquisition function getKey (value) of a bearing value map set to acquire a bearing value map key corresponding to the maximum message bearing value; and taking the bearing value map key as a function input parameter, calling a value acquisition function getvalue (key) of the distribution object map set, and acquiring a secondary distribution object corresponding to the bearing value map key in the distribution object map set as a target secondary distribution object, wherein the object identifier is taken as a key in the distribution object map set, and the secondary distribution object corresponding to the object identifier is taken as a value. The secondary distribution objects and the message bearing values thereof are respectively maintained through the map sets with the consistent map keys, and the secondary distribution objects and the message bearing values thereof can be efficiently managed, so that the load balancing efficiency of the top distribution object for distributing the bullet screen messages is improved.
According to the technical scheme of the embodiment, the necessary load calculation data is improved by obtaining the distribution pressure parameter value corresponding to each secondary distribution object and realizing a load balancing mechanism for the top distribution object. The message pressure-bearing value of each secondary distribution object is determined according to the distribution pressure parameter value of the secondary distribution object and the parameter weight value of the distribution pressure parameter, so that the weighing standard value of the balanced load is more reasonably determined. The target secondary distribution object is determined according to the message bearing value corresponding to each secondary distribution object, and the bullet screen message is distributed to the target secondary distribution object, so that load balance in the bullet screen message distribution process is realized, and the bullet screen message distribution efficiency and the bullet screen message distribution fault tolerance are improved.
Example two
In this embodiment, based on the first embodiment, the "obtaining of the distribution pressure parameter value corresponding to each secondary distribution object" is further optimized. Wherein explanations of the same or corresponding terms as those of the above embodiments are omitted. Referring to fig. 2, the dynamic distribution method of the bullet screen message provided in this embodiment includes:
s210, acquiring the serialized objects corresponding to the secondary distribution objects.
The serialized object is an object that stores serialized data.
Specifically, in order to facilitate the top-level distribution object to obtain the distribution pressure parameter value transmitted by the secondary distribution object, in this embodiment, the secondary distribution object packages the obtained distribution pressure parameter value into an object, and performs a serialization operation on the object, so as to generate a serialized object mSecondResponseStr. Therefore, the top-level distribution object can obtain the distribution pressure parameter value of the secondary distribution object by obtaining the serialized object of the secondary distribution object, and the efficiency of obtaining the distribution pressure parameter value of each secondary distribution object by the top-level distribution object is improved.
It should be noted that the secondary distribution object obtains the value of the distribution pressure parameter in a manner related to the distribution pressure parameter. For example, if the distribution pressure parameter is the historical message bearing capacity and/or the current remaining message bearing rate, the distribution pressure parameter can be obtained by reading log data of the system; for example, if the distribution pressure parameter is the current CPU idle rate and/or the current remaining memory capacity, the distribution pressure parameter may be obtained by reading the system operation state parameter.
Exemplarily, S210 includes: for any secondary distribution object, when the data type of the event object in the event bus is consistent with the data type of the function input parameter of the event message receiving function in the top distribution object, obtaining the event object of the secondary distribution object by calling the event message receiving function as a serialization object corresponding to the secondary distribution object; the event object is a secondary distribution object and is issued to an event bus by calling an event message delivery function through a first event bus object; the top-level distribution object is registered in the event bus in advance by calling a registration function through the second event bus object in the constructor of the top-level distribution class.
The event bus object is an object generated by a third-party open source event bus EventBus, and is an actual executor for realizing the delivery or the reception of the event message. The first event bus object is an event bus object generated in a module to which the secondary distribution object belongs, and the second event bus object is an event bus object generated in a module to which the top distribution object belongs. The event message delivery function is a function in the first event bus object that is used to deliver the event object into the event bus.
Specifically, in order to simplify the communication manner between the secondary distribution object and the top distribution object, improve the communication efficiency between the secondary distribution object and the top distribution object, and reduce the coupling between the secondary distribution object and the top distribution object, in this embodiment, the third-party open source event bus EventBus is used to achieve the acquisition of the distribution pressure parameter value by the top distribution object.
Before performing this operation, each secondary distribution object should have serialized the object encapsulating its distribution pressure parameter value into one serialized object and stored the serialized object into the event object. In addition, each secondary distribution object should pre-generate a first event bus object, mEvenBus1, using the object creation function getdefuaalt in the event bus EventBus. Thereafter, each secondary distribution object issues the above obtained event object into the event bus by calling the event message post () through the first event bus object mEvenBus 1.
On the other hand, if the top-level distribution object is to receive an event message from the event bus EventBus, the top-level distribution object should be registered in the event bus in advance. The registration process is as follows: in the constructor of the top-level distribution class topdemanmanager, a second event bus object mEvenBus2 is generated by calling the object creation function getDefualt in the event bus class EventBus. Thereafter, the top-level distribution object mtopdanmnanager created by instantiation is registered into the event bus EventBus by calling the registration function register (this) in the second event bus object mEvenBus 2. The benefit of placing the registration process in the constructor of the top-level distribution class is to avoid repeated registrations of top-level distribution objects. Similarly, a cancellation function unregister (this) in the second event bus object mEvenBus2 is called in the destruction function onDestory of the top-level distribution class topdemanmanager to register the event bus EventBus back, so that the event message in the event bus is not monitored any more when the top-level distribution class topdemanmanager is destroyed. In addition, a public type is also predefined in the top-level distribution class, an event message receiving function with a returned value of void and a function name of onEventMainThread is also required, and an input parameter of the function is set as a parameter with a unique data type of an event object data type notifiationseconconstrestr, which indicates that the registered top-level distribution object can receive a message with a data type notifiationseconconstrestr.
After all the above operations are completed, the top-level distribution object mtopdannmanager can monitor the event message in the event bus. In particular, the event bus compares the data type of the event object issued by each secondary distribution object with the data type of the function input parameter of the event message receiving function in the top distribution object. When the comparison result is consistent, the event object issued by the secondary distribution object is sent to the event message receiving function. And the top-level distribution object obtains the event object mNotificationsResponseResponseStrr through the event message receiving function oneventMainThread (mNotificationsSecondedResponseStrr). The implementation process inside the event message receiving function is as follows: the function input parameter is assigned to a global variable mnotificationsecontres defined within the top level distribution object by calling this. Since the event object stores the serialized objects, the top level distribution object obtains the serialized objects of the secondary distribution objects.
S220, for any serialized object, the types of the serialized object and a pre-constructed feedback object class are used as function input parameters, an object deserialization function is called, and a distribution pressure parameter value of a current secondary distribution object corresponding to the serialized object is obtained.
Specifically, in order to obtain the distribution pressure parameter value of the secondary distribution object, the serialization operation needs to be performed on each of the obtained serialization objects. Before deserializing operation, an information feedback class SecondResponse capable of storing each distribution pressure parameter value is predefined, each distribution pressure parameter field is defined in the class, and a corresponding field value storage function set and a field value reading function get are set for each distribution pressure parameter, wherein the 'x' represents the corresponding field. If a CPU field storage function setAvaiCpu () and a CPU field reading function getAvaiCpu () are set for the current CPU idle rate cpuAvai field, a corresponding field value storage function and field value reading function are also set for the history message carrying capacity, the current remaining message carrying rate, and the current remaining memory capacity.
In specific implementation, the top-level distribution object uses a serialization object mnotification second response estr and a feedback object class type second response class as function input parameters, calls an object deserialization function parseObject (mnotification second response estr, second response class) with a static identifier static in a JavaScript object notation (JSON) class provided in Java language, and obtains a deserialization result of a serialization object. The first function input parameter of the object deserializing function represents an object to be resolved, the second function input parameter represents the type of a class to be resolved, and a field value storage function set and a field value reading function get in the feedback object are automatically called in the function. The deserialization result is a feedback object mseconddresponse of a feedback object class SecondResponse type, and the feedback object is filled with the corresponding distribution pressure parameter value, so as to obtain the distribution pressure parameter value of the current secondary distribution object corresponding to the serialization object as the input parameter. The above objects are deserialized. By performing the above operations for each serialized object, the values of the distribution pressure parameters for the respective secondary distribution objects can be obtained.
The object deserialization process in this embodiment adopts a more general JSON format in Java language, and when data formats of other character string types are adopted, the corresponding object deserialization function needs to be adopted.
Exemplarily, if the class types of the serialized object and the pre-constructed feedback object are used as function input parameters, an object deserialization function is called, and a result of obtaining a distribution pressure parameter value of the current secondary distribution object corresponding to the serialized object is abnormal, the distribution pressure parameter value is set as a default parameter value, or a message is reported to the feedback data of the current secondary distribution object.
Specifically, in order to improve the fault tolerance of the program, in this embodiment, the object deserialization operation is set in a try structure in a try-catch structure of the fault-tolerant processing code block, and when the result of the object deserialization operation is abnormal, for example, when the object deserialization function returns a return value indicating an operation abnormality, the exception handling code segment in the catch structure is executed. The exception handling mode may be setting a distribution pressure parameter value of the currently processed serialized object as a default parameter value, or feeding back a data report message to the current secondary distribution object through a direct communication channel for bullet screen message distribution, so that the current secondary distribution object reissues the event object. After that, the deserialization operation of the next serialized object is performed.
And S230, aiming at each secondary distribution object, determining the message pressure bearing value of the secondary distribution object according to the distribution pressure parameter value of the secondary distribution object and the parameter weight value of the distribution pressure parameter.
S240, determining a target secondary distribution object according to each message pressure-bearing value corresponding to each secondary distribution object, and distributing the bullet screen message to the target secondary distribution object.
According to the technical scheme of the embodiment, the serialization object in the JSON data format is used for bearing the distribution pressure parameters of the secondary distribution objects, and the object deserialization function corresponding to the JSON data format is used for carrying out serialization processing, so that the efficiency of acquiring the load data of each secondary distribution object by the top distribution object can be further improved, and the efficiency of bullet screen message distribution is further improved.
The following is an embodiment of a dynamic delivery apparatus of a bullet screen message according to an embodiment of the present invention, which belongs to the same inventive concept as the dynamic delivery method of bullet screen messages according to the above embodiments, and reference may be made to the embodiment of the dynamic delivery method of bullet screen messages, for details that are not described in detail in the embodiment of the dynamic delivery apparatus of bullet screen messages.
