Description

Streaming media cascade scheduling method and device, electronic equipment and storage medium

Technical Field

The present invention relates to the field of streaming media technologies, and in particular, to a streaming media cascade scheduling method, apparatus, electronic device, and storage medium.

Background

With the development of internet technology, great convenience is brought to the life of people, for example, by using a streaming media technology, people can watch videos on line instead of completely downloading one video. Streaming media is a technology and process in which a series of media data is compressed, and then sent in segments over the network, and video and audio are transmitted instantly over the network for viewing. By using the streaming media technology, people can realize the buffer while watching only by waiting for a few minutes, thereby saving the waiting time of people for watching videos.

In a usage scenario, a streaming media technology may also be used for live broadcast, for example, live broadcast may be performed by using a live broadcast system as shown in fig. 1, where the live broadcast system includes a capture end 110, a live broadcast source station 120, a CDN node 130, and a play end 140. The acquisition terminal 110 may acquire audio/video information of a live broadcast, and transmit the acquired audio/video information to the live broadcast source station 120 by using a streaming media technology. The live broadcast source station 120 may be configured with a plurality of streaming media servers, and when the playing terminal 140 wants to view the audio and video information of the acquisition terminal 110, a request may be sent to the live broadcast source station 120, then, the streaming media server in the live broadcast source station 120 may distribute the audio and video information to a CDN (Content Delivery Network) node 130 corresponding to the playing terminal 140 by using a streaming media technology for caching, and finally, the CDN node 130 pushes the audio and video information cached by itself to the playing terminal 140.

Because the Nginx technology can implement one main process and multiple work processes, and when one work process is abnormal, the work of other work processes is not affected, so that most streaming media servers in the live source station 120 usually adopt the Nginx technology.

However, when the plurality of working processes receive the streaming media sent by the acquisition end 110, the streaming media are usually cached in respective corresponding memories, and the cached streaming media are not shared among the processes, when the live broadcast source station 120 receives a play request, the live broadcast source station 120 allocates the play request to one process of the streaming media server, and the process only queries whether the streaming media corresponding to the play request exists in its own memory, and if not, returns a non-existing feedback message. However, the streaming media corresponding to the play request may also be cached in the memory of other work processes in the streaming media server, which may cause the feedback message fed back by the live source station 120 to be incorrect.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. 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.

In order to solve the problems in the prior art, embodiments of the present invention provide a streaming media cascade scheduling method, apparatus, electronic device, and storage medium, so as to implement cascade query among processes and improve accuracy of feedback messages fed back.

First, a streaming media cascade scheduling method according to an embodiment of the present invention is introduced below, as shown in fig. 2, which is a flowchart of a first implementation manner of a streaming media cascade scheduling method according to an embodiment of the present invention, where the method may be applied to a first streaming media server, and the method may include:

s210, receiving a streaming media request sent by a user playing end, and inquiring whether streaming media corresponding to the streaming media request exist in a first process of a first streaming media server.

The streaming media request carries identification information of the streaming media to be played, and the first process is a process distributed by the first streaming media server for the streaming media request.

In general, a streaming media service provider may set a streaming media server cluster, and when receiving a streaming media request sent by a user playing end, the streaming media server provider may assign the streaming media request to any streaming media server in the streaming media server cluster for processing.

After receiving the streaming media request, the first streaming media server may locally search, in order to push the corresponding streaming media for the user playing end, whether the streaming media corresponding to the identification information of the streaming media to be played, which is carried in the streaming media request, exists in the first streaming media server.

In some examples, in the streaming process, the first streaming media server allocates the received streaming media to each process of the first streaming media server, and each process is cached in the corresponding memory, so that the first streaming media server may search whether the streaming media to be played exists in the memory corresponding to one process according to the identification information of the streaming media to be played, that is, query whether the streaming media corresponding to the identification information of the streaming media to be played exists in the first process.

For example, for a streaming media server adopting the nginnx technology, the streaming media server may have one host process and multiple work processes, and the host process may select one work process according to the identification information of the streaming media to be played, and the selected work process searches whether the streaming media to be played exists in a memory corresponding to the selected work process.

When it is queried in the first process that there is no streaming media corresponding to the identification information of the streaming media to be played, step S220 may be performed.

S220, inquiring the identification information of the second process corresponding to the identification information of the streaming media to be played in the pre-established corresponding relation between the streaming media and the processes.

The pre-established corresponding relation between the streaming media and the process is established in the stream pushing process, and in the pre-established corresponding relation between the streaming media and the process, the identification information of the streaming media and the identification information of the process have a corresponding relation.

In some examples, when the streaming media to be played is not queried in the first process, the streaming media to be played may also be cached in the memories of other processes, and in order to avoid that the first streaming media server sends the feedback information that is not queried to the user playing end, the streaming media to be played may also be searched in the caches of other processes.

In this regard, the identification information of the second process corresponding to the identification information of the streaming media to be played may be queried in a correspondence relationship between the streaming media and the processes established in advance. The pre-established correspondence between the streaming media and the processes is established based on the identification information of each process and the identification information of the streaming media cached by each process when each process caches the streaming media in the respective memory.

In some examples, the pre-established correspondence between the streaming media and the process may be a correspondence table as shown in table 1.

Table 1 correspondence table between streaming media and process

In table 1, at least one streaming media may be cached in the memory of each process, and therefore, when the corresponding relationship is established, the identification information of one process may at least correspond to the identification information of one streaming media.

Therefore, when the streaming media to be played is cached in the memory of any one of the other processes, the identification information of the process in which the streaming media to be played is cached, that is, the identification information of the second process, can be found by searching in the pre-established correspondence between the streaming media and the process.

S230, acquiring the streaming media to be played corresponding to the identification information of the streaming media to be played from the second process, and sending the acquired streaming media to be played corresponding to the identification information of the streaming media to be played to the user playing end.

After querying the identification information of the second process in which the streaming media to be played is cached, the streaming media to be played corresponding to the identification information of the streaming media to be played can be acquired from the second process, and the acquired streaming media to be played corresponding to the identification information of the streaming media to be played is sent to the user playing end.

In some examples, after the identification information of the second process is queried, the second process may be instructed to transmit the streaming media to be played, which is cached in the memory of the second process and corresponds to the identification information of the streaming media to be played, to the network card of the first streaming media server, and the network card of the first streaming media server is transmitted to the user playing end.

It can be seen that, with the streaming media cascade scheduling method provided in the embodiments of the present invention, when a streaming media request sent by a user playing end is received, it may be first queried in a first process of a first streaming media server whether there is a streaming media corresponding to the streaming media request, if there is no streaming media corresponding to the streaming media request, it may query, according to a pre-established correspondence between the streaming media and the process, identification information of a second process corresponding to identification information of the streaming media to be played, after the identification information of the second process is queried, the streaming media to be played corresponding to the identification information of the streaming media to be played may be obtained from the second process, and finally, the obtained streaming media to be played corresponding to the identification information of the streaming media to be played may be sent to the user playing end. Therefore, when the streaming media to be played is not cached in the first process, the streaming media to be played is obtained from the second process in which the streaming media to be played is cached, so that cascade query can be performed among the processes; when the streaming media to be played is obtained, the streaming media to be played can be sent to the user playing end to be played, so that feedback information which is not queried by the user playing end is prevented from being fed back when the streaming media to be played is not queried in the first process, and accuracy of the feedback information is improved.

In some examples, the correspondence between the pre-established streaming media and the process may be stored in the first streaming media server, and the first streaming media server may set a shared memory for the correspondence between the pre-established streaming media and the process, so that on the basis of the first implementation manner of the streaming media cascade scheduling method shown in fig. 2, an embodiment of the present invention further provides a possible implementation manner, as shown in fig. 3, which is a flowchart of a second implementation manner of the streaming media cascade scheduling method according to the embodiment of the present invention, and the streaming media cascade scheduling method may include:

s310, recording the identification information of each process of the first streaming media server and the identification information of the streaming media cached by each process in the stream pushing process.

S320, according to the identification information of each process and the identification information of the streaming media cached by the process, the corresponding relation between the streaming media and the process is established in advance.

In some examples, after the first streaming media server receives a streaming media sent by the acquisition end, the first streaming media server may select a work process to cache the received streaming media, and may record identification information of the selected process and identification information of the streaming media cached by the selected process.

After the first streaming media server receives the multiple streaming media, the multiple working processes can be selected to cache the received multiple streaming media respectively, and then the identification information of the selected working processes and the identification information of the streaming media cached in each selected working process are recorded.

For example, assume that the first streaming server receives streaming media 1, 2, 3, 4, 5, and 6, and assume that the first streaming server has process 1, process 2, and process 3, which are 3 processes. Then process 1 may be selected to cache streaming media 1 and streaming media 3, process 2 may be selected to cache streaming media 2 and streaming media 4, and process 3 may cache streaming media 5 and streaming media 6, and then the first streaming server may record identification information of process 1, identification information of streaming media 1 and identification information of streaming media 3 cached in process 1, identification information of process 2, identification information of streaming media 2 and identification information of streaming media 4 cached in process 2, and identification information of process 3, identification information of streaming media 6 and identification information of streaming media 3 cached in process 5.

Then, the first streaming media server may pre-establish a correspondence between the streaming media and the process based on the identification information of each process and the identification information of the streaming media cached by the process.

For example, the first streaming media server may establish the correspondence table shown in table 1 based on the identification information of process 1, the identification information of streaming media 1 and 3 cached in process 1, the identification information of process 2, the identification information of streaming media 2 and 4 cached in process 2, the identification information of process 3, the identification information of streaming media 6 and 3 cached in process 5.

In some examples, a shared memory may be set in the first streaming media server for the correspondence table to store the correspondence between the pre-established streaming media and the processes, and each process of the first streaming media server may conveniently access the shared memory to search for the identification information of the second process in the subsequent step.

In some examples, a component may be preset in a first streaming media server in a software manner, after each process of the first streaming media server caches streaming media, the component may send identification information of the process and identification information of the cached streaming media to the component, and the component may establish a correspondence between the streaming media and the process based on the identification information sent by each process and the identification information of the streaming media cached by the process. Therefore, the function of establishing the corresponding relation between the streaming media and the process is realized.

S330, receiving a streaming media request sent by a user playing end, and inquiring whether streaming media corresponding to the streaming media request exist in a first process of the first streaming media server.

When it is queried in the first process that there is no streaming media corresponding to the identification information of the streaming media to be played, step S340 may be performed.

S340, inquiring identification information of a second process corresponding to the identification information of the streaming media to be played in the correspondence between the streaming media and the processes which are pre-established and locally stored in the first streaming media server.

When the streaming media corresponding to the streaming media request is not queried in the first process of the first streaming media server, the first streaming media server may query the identification information of the second process corresponding to the identification information of the streaming media to be played in a correspondence between the streaming media and the process, which is locally stored and established in advance. So as to obtain the streaming media to be played from the queried process of caching the streaming media to be played.

And S350, acquiring the streaming media to be played corresponding to the identification information of the streaming media to be played from the second process, and sending the acquired streaming media to be played corresponding to the identification information of the streaming media to be played to a user playing end.

It is understood that steps S330 and S350 are similar to or the same as steps S220 and S230 in the first embodiment, and are not described again here.

In some examples, when establishing a correspondence between streaming media and processes, a key value table including identification information of each process and identification information of streaming media cached by the process may be established in advance with the identification information of each process as an element value and the identification information of streaming media cached by the process as a field; thereby storing identification information of each process and identification information of the streaming media cached by the process in the form of key-value pairs. Thus, the management of the identification information of each process and the identification information of the streaming media cached by the process can be facilitated.

In some examples, after the key value table including the identification information of each process and the identification information of the streaming media cached by the process is established, when the identification information of the second process corresponding to the identification information of the streaming media to be played is queried, the identification information of the second process corresponding to the identification information of the streaming media to be played may be queried in the pre-established key value table. Therefore, the identification information of the second process corresponding to the identification information of the streaming media to be played can be conveniently inquired, and the time overhead during inquiry is further saved.

By establishing the corresponding relation in the first streaming media server, each process of the first streaming media server can inquire the identification information of the process caching the streaming media to be played in the first streaming media server, so that the streaming media to be played can be acquired, the time overhead during interaction between devices is reduced, and the time spent in the inquiring process is saved.

In some examples, after the key value table is established in advance, since the key value table may periodically clean up the key value pairs that are out of date, for this reason, an indication of updating the key value pairs may be periodically sent to the key value table, so as to ensure that the key value table does not clean up the key value pairs stored in the push flow process. Therefore, when the key value table is queried, the identification information of the process caching the streaming media to be played can be queried.

In some examples, a duration of one period of the sending of the update key-value pairs is less than a duration of a period of the key-value table clearing stale key-value pairs.

In still other examples, a process in which the audio/video capture terminal transmits the streaming media to the first streaming media server is referred to as a stream pushing process, and a process in which the first streaming media server transmits the streaming media requested by the user play terminal to the user play terminal is referred to as a stream pulling process.

In order to reduce the occupation of the shared memory, the embodiment of the present invention further provides a possible implementation manner, and after the audio/video acquisition end completes the process of transmitting the streaming media to the first streaming media server, that is, after the stream pushing process is completed, the pre-established corresponding relationship between the streaming media and the process is deleted. In this way, space for the shared memory may be freed.

In still other examples, the key value table is deleted when the pre-established correspondence between the streaming media and the process is stored in the shared memory in the form of the key value table.

Correspondingly, that is, only when the stream pushing process is performed, the user playing end can acquire the streaming media, and when the stream pushing process is completed, the user playing end cannot acquire the streaming media.

In some examples, after the stream pushing process is completed, the streaming media cached in each process of the first streaming media server is also deleted, and the memory space corresponding to each process is released.

For more clearly explaining the embodiment of the present invention, a signaling interaction process between each process and the scheduling component in the first streaming server is taken as an example to be described here, for example, a signaling interaction diagram between each process and the scheduling component as shown in fig. 4; in fig. 4, a user play end, a process 1, a scheduling component, and a process 2 may be included.

First, process 1 may receive a streaming media sent by an audio/video streaming media acquisition end, and cache the streaming media in its own memory, and then execute step S410.

S410, sending the identification information of the process 1 and the identification information of the streaming media cached in the memory of the process 1.

The scheduling component may execute step S420 after receiving the identification information of the process 1 sent by the process 1 and the identification information of the streaming media cached in the memory of the process 1.

In some examples, the process is described as process 1, and it is understood that the scheduling component may also receive identification information of the process and identification information of the corresponding streaming media sent by other processes of the first streaming media server.

And S420, establishing a key value table by taking the identification information of the process 1 as an element value and the identification information of the streaming media cached in the memory of the process 1 as a field.

In some examples, the scheduling component may perform the same or similar steps as step S420 to establish the key value table after receiving identification information of a process launched by another process and identification information of corresponding streaming media.

When the user at the user playing end wants to watch the streaming media, a streaming media request may be sent to the first streaming media server, that is, step S430 is executed, the streaming media request sent by the user playing end is sent, after the first streaming media server receives the streaming media request, a process may be selected by the first streaming media server to obtain the streaming media corresponding to the streaming media request, and if the process selected by the first streaming media server is process 2, process 2 may receive the streaming media request, and then step S440 may be executed.

S440, finding whether there is streaming media corresponding to the streaming media request.

When the streaming media corresponding to the streaming media request is not cached in the cache of the process 2, the streaming media corresponding to the streaming media request cannot be queried in the memory of the process 2 itself, and at this time, the step S450 may be executed.

S450, sending a query request carrying the identification information of the streaming media to be played.

In some examples, since the streaming media request carries identification information of the streaming media to be played, the process 2 may obtain the identification information of the streaming media to be played from the streaming media request, add the identification information to the query request, and send the query request to the scheduling component. The scheduling component, upon receiving the query request, may perform step S460.

S460, inquiring identification information of the process 1 corresponding to the identification information of the streaming media to be played.

Here, assuming that the process in which the streaming media to be played is cached is process 1, the scheduling component may query, in its key value table, the identification information of the process corresponding to the identification information of the streaming media to be played, that is, the identification information of process 1, based on the identification information of the streaming media to be played. After querying the process identification information corresponding to the identification information of the streaming media to be played, that is, the identification information of process 1, step S470 may be executed.

S470, sending the identification information of the process 1 to the process 2. So that the process 1 can send the streaming media to be played to the user playing end through the subsequent steps. After receiving the identification information of process 1, process 2 may send an inquiry request to process 1, that is, execute step S480.

S480, sending a sending instruction carrying the identification information of the streaming media to be played to the process 1.

Process 1, upon receiving the transmission instruction, may perform steps S490 and S500.

S490, searching the streaming media corresponding to the identification information of the streaming media to be played.

S500, the streaming media to be played is sent to a user playing end.

Therefore, through the embodiment of the invention, when the streaming media to be played is not cached in the process 2, the process 1 caching the streaming media to be played can be inquired, and then the process 1 can send the streaming media to be played to the user playing end, so that feedback information which cannot be inquired can not be fed back to the user playing end when the streaming media to be played is not cached in the process 2.

In some examples, the correspondence between the streaming media and the process that are established in advance may also be stored in a scheduling server, for which, on the basis of the first implementation manner of the streaming media cascade scheduling method shown in fig. 2, an embodiment of the present invention further provides a possible implementation manner, as shown in fig. 5, which is a flowchart of a third implementation manner of the streaming media cascade scheduling method according to the embodiment of the present invention, and the streaming media cascade scheduling method may include:

and S510, recording identification information of each process of the first streaming media server and identification information of the streaming media cached by each process in the stream pushing process.

S520, the identification information of each process and the identification information of the streaming media cached by each process are sent to a scheduling server, so that the scheduling server establishes the corresponding relation between the streaming media and the process in advance according to the identification information of each process and the identification information of the streaming media cached by the process.

In some examples, after the first streaming media server records the identification information of each process and the identification information of the streaming media cached by the process in the stream pushing process, the identification information of the process and the identification information of the streaming media cached by the process in the stream pushing process may also be sent to the scheduling server.

The scheduling server, after receiving the identification information of the process and the identification information of the streaming media cached in the process of pushing the stream, may locally establish a correspondence between the streaming media and the process in the scheduling server based on the received identification information of the process and the identification information of the streaming media cached in the process.

In some examples, when the scheduling server establishes a correspondence between the streaming media and the process in advance according to the identification information of each process and the identification information of the streaming media cached by the process, the scheduling server may establish a key value table containing the identification information of each process and the identification information of the streaming media cached by the process in advance by using the identification information of each process as an element value and using the identification information of the streaming media cached by the process as a field.

In some examples, a shared memory may be set in the scheduling server for the correspondence table to store the correspondence between the pre-established streaming media and the processes, and each process of the first streaming media server may conveniently access the shared memory to search for the identification information of the second process in the subsequent step.

S530, receiving a streaming media request sent by a user playing end, and inquiring whether streaming media corresponding to the streaming media request exist in a first process of a first streaming media server.

When it is queried in the first process that there is no streaming media corresponding to the identification information of the streaming media to be played, step S540 may be performed.

And S540, sending a query request carrying the identification information of the streaming media to be played to the scheduling server, so that the scheduling server searches the identification information of the second process corresponding to the identification information of the streaming media to be played in the correspondence between the streaming media and the processes which is established in advance locally, and feeds back the identification information of the second process.

When the streaming media corresponding to the streaming media request is not queried in the first process of the first streaming media server, the first streaming media server may send a query request carrying identification information of the streaming media to be played to the scheduling server, so that the scheduling server can query.

After receiving the query request, the scheduling server may search for identification information of a second process corresponding to the identification information of the streaming media to be played in a correspondence between the streaming media and the processes which is established in advance locally. When the scheduling server finds the identification information of the second process, the identification information of the second process can be fed back to the first streaming media server.

In some examples, when the above-mentioned scheduling server establishes a key value table locally, the scheduling server may look up the identification information of the second process corresponding to the identification information of the streaming media to be played in the key value table established locally in advance.

And S550, acquiring the streaming media to be played corresponding to the identification information of the streaming media to be played from the second process corresponding to the identification information of the second process sent by the scheduling server, and sending the acquired streaming media to be played corresponding to the identification information of the streaming media to be played to the user playing end.

After receiving the identification information of the second process sent by the scheduling server, the first streaming media server may obtain the streaming media to be played corresponding to the identification information of the streaming media to be played from the second process based on the identification information of the second process, and send the obtained streaming media to be played corresponding to the identification information of the streaming media to be played to the user playing end.

It is understood that step S530 is similar to or identical to step S220 in the first embodiment, and is not described herein again.

In the embodiment of the invention, the corresponding relation is established by the scheduling server, so that the corresponding relation can be conveniently maintained on the basis of realizing the aim of the embodiment of the invention, and the streaming media server only needs to inquire.

In some examples, after the key value table is established in advance, since the key value table may periodically clean up the key value pairs that are out of date, for this reason, an indication of updating the key value table may be periodically sent to the scheduling server, so as to ensure that the key value table does not clean up the key value pairs stored in the push flow process. Therefore, when the key value table is queried, the identification information of the process caching the streaming media to be played can be queried.

In some examples, in order to reduce the occupation of the shared memory of the scheduling server by the corresponding relationship, embodiments of the present invention further provide a possible implementation manner, after the audio/video acquisition end completes the process of transmitting the streaming media to the first streaming media server, that is, after the stream pushing process is completed, the corresponding relationship between the streaming media and the process that is pre-established in the scheduling server is deleted. In this way, space for the shared memory may be freed.

In still other examples, when the pre-established correspondence between the streaming media and the process is stored in the scheduling server in the form of a key value table, the key value table is deleted.

On the basis of the streaming media cascade scheduling method shown in fig. 2, an embodiment of the present invention further provides a possible implementation manner, and as shown in fig. 6, the method is a flowchart of a fourth implementation manner of the streaming media cascade scheduling method according to the embodiment of the present invention, and the method may include:

And S630, sending the identification information of the first streaming media server, the identification information of each process in the first streaming media server and the identification information of the streaming media cached by each process to the scheduling server, so that the scheduling server establishes the corresponding relation among the streaming media, the processes and the streaming media server in advance according to the identification information of the first streaming media server, the identification information of each process in the first streaming media server and the identification information of the streaming media cached by each process.

In some examples, after the first streaming media server receives a plurality of streaming media, a plurality of work processes may be selected to cache the received plurality of streaming media, and identification information of the selected work processes and identification information of the streaming media cached in each selected work process may be recorded. Then, the corresponding relation between the streaming media and the process can be established in advance based on the identification information of each process and the identification information of the streaming media cached by the process.

In some examples, the other streaming media servers belonging to the same streaming media server cluster as the first streaming media server may also establish the corresponding relationship between the respective streaming media and the process in the respective streaming media servers through the same or similar steps as those in steps S610 and S620 described above.

In some examples, in order to implement process scheduling among multiple servers in subsequent steps, the first streaming media server may further send identification information of the first streaming media server, identification information of each process in the first streaming media server, and identification information of streaming media cached by each process to a scheduling server, where the scheduling server may, after receiving the identification information of the first streaming media server sent by the first streaming media server, the identification information of each process in the first streaming media server, and the identification information of streaming media cached by each process, pre-establish a correspondence relationship between the streaming media, the process, and the streaming media server based on the identification information of the first streaming media server, the identification information of each process in the first streaming media server, and the identification information of streaming media cached by each process.

In still other examples, the other streaming media servers connected to the scheduling server may also send the identification information of the other streaming media servers, the identification information of each process of the other streaming media servers, and the identification information of the streaming media cached by each process to the scheduling server, so as to establish a corresponding relationship between the streaming media, the process, and the streaming media server.

For example, a correspondence table of streaming media, processes, and streaming media servers as shown in table 2 may be established. In table 2, each streaming server may have at least one process, for example, the streaming server 1 may have a process 1 and a process 2, the streaming server 2 may have a process 3 and a process 4, and the streaming server 3 may have a process 5 and a process 6. At least one streaming media may be cached in the memory of each process, for example, the streaming media 1 may be cached in the process 1 of the streaming media server 1, and the streaming media 4 may be cached in the process 3 of the streaming media server 2.

It should be understood that the processes may be counted from 1 in each streaming server, and the processes are cumulatively counted by the number of processes in each streaming server for distinction in table 2.

Therefore, the correspondence relationship shown in table 2 may be established based on the identification information of the streaming server sent by each streaming server, the identification information of the process in the streaming server, and the identification information of the streaming media cached in each process.

The acquisition request may carry identification information of the second process, so that the second streaming media server determines the process of the streaming media to be played.

After receiving the acquisition request carrying the identification information of the second process, the second streaming media server may acquire the streaming media corresponding to the identification information of the streaming media to be played from the second process based on the identification information of the second process, and send the streaming media to the first streaming media server.

After receiving the streaming media corresponding to the identification information of the streaming media to be played, the first streaming media server may send the streaming media to be played corresponding to the identification information of the streaming media to be played to the user playing end, so that the user playing end plays the streaming media to be played.

By the embodiment of the invention, when the streaming media corresponding to the streaming media request is not cached in the first streaming media server, the streaming media server cached with the streaming media corresponding to the streaming media request and the process cached with the streaming media corresponding to the streaming media request can be determined, and then the streaming media is acquired from the streaming media server cached with the streaming media corresponding to the streaming media request and is sent to the user playing end. And then, the cascade scheduling among a plurality of streaming media servers can be realized, the corresponding streaming media can be found for the user playing end as much as possible, and the user experience is improved.

In some examples, in order to reduce the occupation of the storage space of the scheduling server, after the stream pushing process of the first streaming media server is completed, a deletion request for deleting the correspondence may be sent to the scheduling server, so as to delete the identification information of the first streaming media server, the identification information of each process of the first streaming media server, the identification information of the streaming media cached in each process of the first streaming media service, and the corresponding correspondence. In this way, the occupation of the storage space of the scheduling server can be reduced.
