Detailed Description
The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present application, and not all 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 application.
With the continuous development of the live broadcast industry, various live broadcast platforms are gradually emerging. Because the live broadcast watching platforms used by each user are different and the live broadcast watching platforms of the anchor are different, if the live broadcast of the anchor is only played on one platform, the user cannot watch the live broadcast through other platforms, and the exposure and the flow of the anchor are limited. In order to improve exposure and flow of the anchor, live broadcast data of the anchor on a live broadcast platform can be distributed to other platforms to increase exposure and flow of the anchor, namely, the live broadcast platform and the other platforms are in intermodal connection, so that a user can watch live broadcast of the anchor on another platform or directly enter a live broadcast room of the anchor, and the method is also favorable for improving user viscosity.
The inventor finds that, in the live broadcast intermodal transportation process, both platforms are in a data service mode of a single server, namely, a server on one side executes a synchronization task to synchronize data to be synchronized to a server on the other side. In order to improve the above technical problem, the present application proposes the following embodiments.
As shown in fig. 1, the live intermodal system embodiment of the present application may include a synchronization server cluster 100, a live server 300, and an intermodal server 400. When the anchor is in the live process, the live server 300 may store and manage live data generated in the live process. The live broadcast data in the live broadcast server 300 can be synchronized to the intermodal server 400 through the synchronization server cluster 100, so that the intermodal server 400 can also synchronously play the same picture as the main broadcast in the live broadcast server 300 in the live broadcast process, and a user can watch the same live broadcast picture in different platforms through a user side.
The synchronization server cluster 100 may refer to a cluster including at least two groups of servers, each group including at least two servers deployed in a cluster configuration. The cluster structure can be regarded as a single-machine multi-instance, a plurality of service nodes can be formed by deploying a plurality of servers, the plurality of service nodes can be aimed at the same service, only one server point processes the service in one processing process, and other service nodes can be used as backup service nodes. After a service node that processes traffic fails, then other backup service nodes may process the traffic. The cluster architecture may further be a distributed cluster architecture.
The live broadcast server 300 may be a server used by a business party for live broadcast, all live broadcast data generated by all anchor broadcasts currently live broadcast on the platform are stored in the live broadcast server 300, and managers may perform operations such as order management and traffic distribution on live broadcast through the live broadcast server 300.
The intermodal server 400 may refer to a server used by the intermodal party to synchronize live data of the business parties. The live broadcast data in the live broadcast server 300 is synchronized to the intermodal server 400 through the synchronization server cluster 100, and after receiving the live broadcast data, the intermodal server 400 can play a live broadcast picture which is the same as that of the business party on the intermodal party. That is, the user can view the live broadcast picture of the main broadcast on different platforms, so that on one hand, the exposure and the flow of the main broadcast can be increased, and on the other hand, the user viscosity can also be improved.
The embodiment of the method for synchronizing live broadcast intermodal data of the present application may be applied to the live broadcast intermodal system described in the embodiment of the live broadcast intermodal system, where the synchronization server cluster 100 is used as an execution perspective in the embodiment, and the method may include: s100: a target server for performing synchronization is determined in a cluster of synchronization servers. S200: and acquiring the current live broadcast data to be synchronized corresponding to the server group to which the target server belongs. S300: and synchronizing the current live data to be synchronized to the intermodal server based on the target server.
The target server for executing synchronization is determined in the synchronization server cluster 100, because the synchronization server cluster 100 includes at least two groups of server groups, different server groups respectively correspond to corresponding live broadcast data to be synchronized, and each group of server groups includes at least two servers deployed in a cluster structure, when a certain server of the same server group fails or cannot execute synchronization, other servers of the same server group can be determined as target servers to execute synchronization, then current live broadcast data to be synchronized corresponding to the server group to which the target server belongs is obtained, and the corresponding current live broadcast data to be synchronized is synchronized to the intermodal server 400 based on the target server, so that different server groups respectively correspond to corresponding live broadcast data to be synchronized by the synchronization server cluster 100, even if the volume of the live broadcast data is large, different server groups can share respective live broadcast data to be synchronized, data processing pressure of each server group is reduced, stability of the whole intermodal system can be improved, a target server is determined in at least two servers deployed in a cluster structure of each server group, and then the live broadcast data to be synchronized corresponding to the server group is synchronized to the intermodal server 400, unavailability of the whole intermodal system caused by faults of a single server can be reduced, high availability is achieved, and stability and reliability in a live broadcast intermodal process are effectively improved.
The method described in this embodiment can be applied to a live combined transport scenario, and the following describes the embodiment in detail with the synchronization server cluster 100 as an execution subject.
As shown in fig. 2, the present embodiment may include the following steps:
s100: a target server for performing synchronization is determined among a cluster of synchronization servers.
The synchronization server cluster 100 may refer to a cluster including at least two groups of servers, each group including at least two servers deployed in a cluster configuration. For example, as shown in fig. 3, the synchronization server cluster 100 may include n rooms, each room includes m servers, the servers in each room are identified from 1, 2.. m, the same server in each room is identified as a server group, and the server groups are divided by a first group number, where the first group number corresponds to a number in the process of identifying the server, for example, the first group number of the server group corresponding to the server with the identifier 1 in each room is 1. Through repeated grouping of multiple computer rooms, the data in each server can be backed up by other servers in the same server group, and therefore the availability and reliability of the intermodal process are guaranteed.
The target server may be a server for performing synchronization, that is, during live intermodal transport, live data of a business party (e.g., live platform) is synchronized to an intermodal party (e.g., intermodal platform) through the target server 400, thereby enabling the intermodal party to play the same live picture as the business party. For example, the servers of each server group in the synchronization server cluster 100 may determine the server for performing the task in a competitive manner, or according to a predetermined order, or the like, or the servers may determine the server for performing the synchronization task, i.e., the target server, in other prior art means.
In one implementation, with respect to how to determine a target server for performing synchronization in the synchronization server cluster 100, reference may be made to the following steps included in S100:
s110: a group of servers is determined in the cluster of synchronization servers, and a server is determined as a target server in the determined group of servers.
Specifically, since the synchronization server cluster 100 may include at least two groups of server groups, and each group of server groups includes at least two servers deployed in a cluster structure, the target server for performing synchronization in the synchronization server cluster 100 may be determined by determining a group of server groups and then determining the target server in the group of server groups.
Specifically, for how to determine the target server, see the following steps included in S110:
s111: controlling all servers in each server group to rob locks by using the same lock key; wherein, different server groups correspond to different keys.
Preempting a lock with the same lock key may refer to determining a target server by preempting a distributed lock. The distributed lock preemption can be realized by a redis master library, and all servers in each server group are controlled to preempt the lock in one place. Lock preemption is a competition between groups of servers and is further competitive among the servers within the group of servers. For example, when there are m server groups in the synchronization server cluster 100, each server group may be assigned a key1、key2...keymWhen the target server needs to be determined, the setnx instruction in the redis master library can be used for controlling the lock keys of each group to perform lock grabbing, and whether the lock grabbing succeeds or not can be judged according to a return value of the setnx instruction after the lock grabbing is completed. For example, when there are 3 servers distributed in each server group, if the first server of the group robs the lock, the first corresponding setnxkey1Is 1, the return value of setnxkey1 corresponding to the second station is 0, and the return value of setnxkey1 corresponding to the third station is 0.
S112: and determining the server which successfully robs the lock as the target server.
When the return value of the instruction for controlling the lock key to rob the lock is 1, the server can be judged to rob the lock successfully, and the server with the successful lock robbing is taken as the target server. In each lock grabbing process, only one server can grab the lock to become a target server, when the target server executes the synchronization task, the distributed lock is released, and then other servers can continue to grab the lock to execute the synchronization task.
S200: and acquiring the current live broadcast data to be synchronized corresponding to the server group to which the target server belongs.
Different server groups respectively correspond to corresponding live broadcast data to be synchronized. The live data to be synchronized currently can be data which needs to be synchronized by a business party to an intermodal party, and the live data to be synchronized currently is sent to the intermodal server 400 through a target server in the business party, so that after receiving the live data to be synchronized currently, the intermodal server 400 can play a live picture corresponding to the live data to be synchronized currently for a user to watch.
In one implementation, as shown in fig. 4, before acquiring live data to be synchronized currently corresponding to a server group to which a target server belongs, the following steps may be included:
s210: acquiring live broadcast data of all live broadcast rooms currently in live broadcast, and respectively configuring a second group number for the live broadcast data of all the live broadcast rooms so as to carry out grouping; the second group number of the live data of each live broadcast room corresponds to the first group number of the corresponding server group.
The acquiring of the live broadcast data of all live broadcast rooms currently in live broadcast may be to query live broadcast data of a live broadcast room in live broadcast from a live broadcast list in a preset service server, or to query live broadcast data of a live broadcast room distributable to the intermodal server 400. The service server can provide distributable live broadcast list, cover title maintenance, black and white list maintenance, order penalty and the like. The order penalty may be triggered when a violation occurs in the live broadcast, such as smoking, yellow-related, or political-related scenes.
The live data currently to be synchronized may include base data, low frequency update data, and high frequency update data. The basic data is data which cannot be changed in the live broadcast process, and the frequency of the low-frequency updating data changing in the live broadcast is lower than that of the high-frequency updating data changing in the live broadcast. By grouping the current live data to be synchronized, the synchronization of all data caused by unpredictable faults of a certain node can be prevented from occurring, and the reliability in the intermodal process is further improved. Specifically, UID, anchor title, nickname, level, category, tag, and live broadcast room number may be defined as basic data, live broadcast room jump address, cover, title, and live broadcast stream information may be defined as low-frequency update data, and online number of people, present number, comment number, and PK status may be defined as high-frequency update data. Specifically, the live streaming information may be a character string in a json format, and includes video streaming addresses in high-definition, standard-definition and other gears, so that when the client receives the streaming information, the client can enable the viewer to select which gear to watch.
The current live broadcast data to be synchronized can also comprise a channel number and a live broadcast room identification number, and a user can quickly find a corresponding live broadcast room in a plurality of live broadcast rooms according to the channel number or the live broadcast room identification number.
The live data to be currently synchronized may further include scene control data, where the scene control data is used to control a scene in which the live data to be currently synchronized is distributed at the intermodal server 400. Specifically, for each intermodal access intermodal server 400, a distributable live broadcast list SCENE may be subdivided into various SCENE values such as a feed SCENE (SCENE1), a channel page (SCENE2), a vertical sliding (SCENE3), and as shown in fig. 5, a in fig. 5 is a feed SCENE page of a certain platform mobile phone end, and a feed SCENE may refer to a SCENE corresponding to an information stream that needs to be continuously updated and presented to user content, for example, when a live broadcast picture of a certain anchor needs to be pushed to a feed SCENE, the anchor may be pushed to a SCENE where a video 1 in a recommendation column in a in fig. 5 a is located, so as to improve the exposure rate of the anchor. Fig. 5 b shows a channel page scene of a mobile phone end of a certain platform, which may be divided into, for example, a video channel, a color channel, a music channel, a funny channel, and the like, and specifically, a live broadcast frame of a main broadcast may be pushed to a scene where a video 2 is located as in fig. 5. In fig. 5, c is a top-down sliding scene of a certain platform, a user can switch a video to be watched by sliding up and down, and a live frame of a main broadcast can be pushed into a scene where a video 3 is located as in fig. 5. And one switch for distribution control is defined for each SCENE value, schene-1 indicates distributable, and schene-0 indicates non-distributable. The scenario value may be determined by a business party negotiating with the intermodal server 400 before intermodal. When determining a scene in which the current live data to be synchronized is distributed in the intermodal server 400, the operator may perform dynamic adjustment according to a white list in the service server. By independently controlling each distribution scene, more refined operation can be performed on each anchor, and the flow distribution of medium and small anchors is more reasonable.
The live data to be synchronized currently may further include a check code, which is encoded using at least the base data, the low frequency update data, and the scene control data.
As to how to configure the second group number for grouping the live data of all live rooms, the following steps included in S210 may be referred to:
s211: and respectively taking the channel numbers of the live broadcast data of all the live broadcast rooms as the remainder of the total number of the server group, and taking the sum of the remainder and 1 as the respective second group number.
In the process of grouping all live broadcast data of each live broadcast room, a remainder is respectively taken from the channel number corresponding to each live broadcast room to the total number of the server group, and the sum of the remainder and 1 is used as a second group number of each channel number. Grouping is carried out based on the channel number, all live broadcast data of a live broadcast room of the same channel can be executed in the same server group, and the condition that one execution cycle is in one server group, and the other execution cycle is in the other server group to cause disorder is avoided. For example, when the channel number CID of a certain live broadcast room is 30879870 and the total number m of the server group is 3, the second group number CID% m +1 is 30879870% 3+1 is 1, and since the second group number of the live broadcast data of each live broadcast room corresponds to the first group number of the corresponding server group, and since the second group number corresponding to the live broadcast data is 1, the first group number of the server group corresponding to the live broadcast data is also 1.
In one implementation, after grouping live data of all live rooms, refer to the following steps:
s220: and writing the live broadcast data of all live broadcast rooms into a preset database by taking respective live broadcast room identification numbers as main keys.
A primary key, which may refer to a column or a combination of columns, has a value that uniquely identifies each row in the table. The primary key is mainly used for associating with the external key of other tables and modifying, updating and deleting the text records. And writing the live broadcast data of all live broadcast rooms into a preset database by taking respective live broadcast room identification numbers as main keys, and operating through respective live broadcast room identification numbers when modifying and deleting the live broadcast data of all live broadcast rooms.
In one implementation, for how to obtain the current live data to be synchronized corresponding to the server group to which the target server belongs, reference may be made to the following steps included in S200:
s230: and inquiring and acquiring the corresponding current live broadcast data to be synchronized in a preset database by using the first group number of the server group to which the target server belongs.
After the live broadcast data of all live broadcast rooms are written into a preset database, the current live broadcast data to be synchronized corresponding to the server group to which the target server belongs can be inquired in the database. Specifically, when the live data to be currently synchronized is obtained, the live data corresponding to the second group number corresponding to the first group number may be queried in the preset database by using the first group number of the server group to which the target server belongs, and the live data is used as the live data to be currently synchronized. For example, when the first group number of the server group to which the target server belongs is 1, live data with the second group number of 1 corresponding to the first group number of 1 is inquired in the database, and whether the synchronization state in the live data is stopped is detected, if the synchronization state of the live data is not stopped, the live data is the current live data to be synchronized.
S300: and synchronizing the current live data to be synchronized to the intermodal server based on the target server.
After determining the target server for performing synchronization and the live data to be synchronized currently, the target server may synchronize the live data to be synchronized currently to the intermodal server 400, so that the intermodal party can play the live data to be synchronized currently received by the intermodal server 400, so that the audience can also watch the live broadcast performed by the main broadcast on the platform of the business party at the intermodal party.
Specifically, for how to synchronize the live data to be currently synchronized to the intermodal server 400 based on the target server, the following steps included in S300 can be referred to:
s310: and acquiring the synchronization state of the current live data to be synchronized, and carrying out synchronization operation corresponding to the synchronization state on the current live data to be synchronized to the intermodal server through the target server.
The synchronization state may be state data maintained by the service side itself, the synchronization state may include to-be-synchronized, to-be-updated, synchronized, to-be-off-air, and corresponding synchronization operation may be performed based on different synchronization states.
In one implementation, S310 may include the following operation steps:
s311: and if the synchronization state is to be synchronized, synchronizing the live broadcast data to be synchronized to the intermodal server.
When the live data to be synchronized is taken from the live list in the service server for the first time, that is, when the anchor is just started to play and the live data is just started to be generated, the synchronization state at this time is to be synchronized. Specifically, when the synchronization state is to be synchronized, the creation interface of the intermodal transport is called to perform synchronization, and when the interface returns a success, it indicates that the live data to be synchronized is synchronized to the intermodal transport server 400, and at this time, the synchronization state is updated to be synchronized.
S312: and if the synchronization state is to be updated, synchronizing the low-frequency update data in the live broadcast data to be synchronized to the intermodal server.
Because the low-frequency update data in the live broadcasting process can be changed, in order to timely carry out link transport on the updated data, the current live broadcasting data to be updated, which is acquired by the target server, can be compared with the low-frequency update data in the live broadcasting data corresponding to the live broadcasting list of the service server at preset intervals, and when the low-frequency update data in the current live broadcasting data to be updated, which is acquired by the target server, is inconsistent with the low-frequency update data in the live broadcasting data corresponding to the live broadcasting list of the service server, the synchronization state at the moment is to be updated. And when the synchronization state is to be updated, the low-frequency updating interface can be called to synchronize the low-frequency updating data. If the low-frequency update interface returns success, it indicates that the low-frequency update data in the live broadcast data to be synchronized has been synchronized to the intermodal server 400, and at this time, the synchronization state is updated to be synchronized.
S313: and if the synchronization state is to-be-stopped, stopping synchronizing the current live broadcast data to be synchronized with the intermodal server.
When the anchor on live is penalized in order, the synchronization status can be set to pending outage. At this point, a stop interface may be invoked to stop synchronizing the live data currently to be synchronized to the intermodal server 400. If the stop interface returns a success, it indicates that the synchronization of the live data to be synchronized to the intermodal server 400 has been stopped, and at this time, the synchronization status is updated to be stopped.
In an implementation manner, the updating of the synchronization status to the stopped state may also be that when the target server obtains live data from a live list in the service server, it finds that there is no live data in the live list, and then the anchor broadcast is considered to have been stopped, at this time, no live data is generated, and then there is no live data in the live list, and then the synchronization status may be updated to the stopped broadcast.
S314: and if the synchronous state is not the stopped broadcast, synchronizing the high-frequency updating data of the current live broadcast data to be synchronized with the transport server at intervals of a first preset time.
Since the high-frequency update data in the live broadcast process is data whose change frequency is high, it is necessary to perform intermodal transportation to the intermodal server 400 at a high frequency. Therefore, when the synchronization status is not off-air, that is, when the anchor is in the process of live broadcasting, the high-frequency update data of the live broadcasting data to be currently synchronized can be synchronized with the intermodal server 400 at intervals of the first preset time. In the process of synchronizing the high frequency update data, the high frequency update data is synchronized to the intermodal server 400 by calling the high frequency update interface, and if the interface returns success, it indicates that the high frequency update data has been synchronized to the intermodal server 400. For example, in the live broadcast process of the anchor, the audience will give a gift to the anchor to indicate the support of the anchor, and the popular anchor will receive more gifts in the live broadcast process, so in the live broadcast process, the number of the gift-sending is determined as high-frequency update data, and the number of the gift-sending can be synchronized to the intermodal server 400 by calling the high-frequency update interface every 1s, thereby improving the timeliness and reliability in the intermodal process. By dividing the high-frequency updating data and the low-frequency updating data and calling different interfaces, the high-frequency updating data and the low-frequency updating data are synchronized under different conditions, the data volume of data synchronization between services can be reduced, the bandwidth pressure is reduced, and the stability in the intermodal transport process is further improved.
In one implementation, S310 may include the following steps after:
s320: and updating the synchronization state of the live data to be synchronized after the synchronization operation is successful.
The successful synchronization operation may refer to a case that the interface returns a success after the different interfaces are called to synchronize the live data to be updated. Based on the called interface and the current live data to be synchronized corresponding to the synchronization operation, the synchronization state can be updated. For example, when the low-frequency update interface is called to synchronize the low-frequency update data, the synchronization status may be updated to synchronized when the interface returns success. For another example, when the call stop interface stops synchronizing the live data currently to be synchronized to the intermodal server 400, when the interface returns a success, the synchronization status may be updated to be stopped.
S330: and acquiring the live broadcast room identification number and the check code returned by the intermodal server at intervals of a second preset time, wherein the check code is formed by at least utilizing basic data and low-frequency updating data codes.
After the service party intermodal server 400 successfully synchronizes the live data to be synchronized currently, in order to ensure the accuracy of intermodal transportation, the intermodal transportation party and the service party can check the intermodal transportation content by convention. Specifically, after receiving the live data to be synchronized currently, the intermodal server 400 may send the live room identification number and the check code in the received live data to be synchronized currently back to the service side, and the service side may provide an interface to receive the live room identification number and the check code sent back by the intermodal server 400. For example, the intermodal server 400 may send the live broadcast identification number and the check code to be checked to the service party every 5s according to the agreement with the service party. The consistency of the data of both parties of the intermodal transportation can be further ensured by regularly checking the data, the inconsistency of the data of both parties of the intermodal transportation caused by the failure of synchronization of a certain time in the midway can be avoided, and the accuracy in the intermodal transportation process can be improved.
S340: and judging whether the live broadcast room identification number and the check code returned by the intermodal server are consistent with the check code currently corresponding to the live broadcast room identification number of the target server.
After receiving the live broadcast room identification number and the check code sent back by the intermodal server 400, comparing the live broadcast room identification number and the check code sent back by the intermodal server 400 with the check code corresponding to the same live broadcast room identification number in the service side, and judging whether the live broadcast room identification number and the check code are consistent. Since the check code is formed by encoding at least the base data and the low frequency update data, for example, the base data, the scene control data, and the low frequency update data may be encoded into the check code, and if the check code is inconsistent, at least one of the base data, the scene control data, and the low frequency update data may be considered to be inconsistent.
S350: and if the live broadcast data are inconsistent, updating the synchronization state corresponding to the live broadcast room identification number to be updated, and synchronizing the low-frequency update data in the current live broadcast data to be synchronized with the intermodal server.
If the data is inconsistent, the data can be judged to be inconsistent, and synchronization failure occurs in the intermodal process. At this time, the synchronization state corresponding to the live broadcast room identification number received from the intermodal server 400 may be updated to be updated, and a synchronization operation of updating data through a low frequency in the live broadcast data to be currently synchronized to the intermodal server 400 may be performed. Specifically, the operation of synchronizing the live broadcast data to be currently synchronized with the intermodal server 400 through the low-frequency update data in the live broadcast data is performed as described in S312, and therefore, the description is omitted here.
To sum up, in the live broadcast intermodal data synchronization method of this embodiment, when live broadcast intermodal data needs to be performed between a service party and an intermodal party, a target server for performing synchronization is determined in a synchronization server cluster 100 preset by the service party, and since servers in the synchronization server cluster 100 are deployed in a cluster structure, that is, data in servers of the same server group are the same, it can be ensured that each current live broadcast data to be synchronized has backed-up data that can be synchronized by a multi-computer room service node, and availability and reliability of an intermodal process are ensured. Then, the channel numbers of the live broadcast data obtained from the live broadcast list of the service server respectively take the remainder of the total number of the server groups, the sum of the remainder and 1 is used as the respective second group number, and the second group number of the live broadcast data of each live broadcast room corresponds to the first group number of the corresponding server group. And then, determining the current live broadcast data to be synchronized corresponding to the target server based on a second group number corresponding to the first group number of the server group to which the target server belongs, and synchronizing the current live broadcast data to be synchronized according to the synchronization state by calling different interfaces. After the direct live broadcast data synchronization of the two intermodal parties is completed, the intermodal parties can check the live broadcast data through the live broadcast room identification number and the check code, judge whether the live broadcast room identification number and the check code received by the intermodal server 400 are consistent with the live broadcast room identification number and the check code in the service party, and if the live broadcast data are not consistent with the live broadcast room identification number and the check code, the live broadcast data are synchronized by calling the interface again.
For example, when the first group number of the server group corresponding to the target server is 1, the channel number CID of a certain live broadcast room is 30879870, and the total number m of the server group is 3, the second group number CID% m +1 ═ 30879870% 3+1 ═ 1, into which all live broadcast data corresponding to the live broadcast room are divided, then according to the first group number of the target server, all live broadcast data with the channel number CID 30879870 can be inquired in the database, that is, all live broadcast data in the live broadcast room are currently to be synchronized, if the target server first obtains all live broadcast data in the live broadcast room from the database, the synchronization state is to be synchronized, a creation interface is called, the currently to be synchronized live broadcast data are synchronized to the intermodal server 400, so that the intermodal server 400 can receive all live broadcast data with the channel number CID 30879870, and play the live broadcast room in the intermodal party according to a predetermined distribution scene, thus realizing the intermodal transportation between the business party and the intermodal transportation party.
