Referring to fig. 3, fig. 3 is a schematic flow chart of a cloud game thermomigration method according to an embodiment of the present application, which will be described with reference to steps 101 to 104 shown in fig. 3, and the cloud game thermomigration method according to an embodiment of the present application may be implemented by a server or a terminal alone or by a server and a terminal cooperatively, and will be described below by taking a scheduling server alone as an example.

In step 101, operational information for each of a plurality of cloud game servers is obtained, the operational information including a number of cloud game instances running on the cloud game server based on the container.

In some embodiments, the container is an operating system independent environment for running applications. The container is a special process running on the host machine, and multiple containers are used among operating system kernels of the same host machine.

In some embodiments, one container is carried on the cloud game server, and one cloud game instance is executed, that is, each container corresponds to one cloud game instance, that is, the number of cloud game instances executed on the cloud game server is equal to the number of containers carried on the cloud game server.

In some embodiments, the operational information of the cloud game server includes a number of cloud game instances on the cloud game server that are running based on the container, i.e., a number of cloud game instances on the cloud game server that are running, i.e., a number of containers on the cloud game server that are running.

As an example, referring to fig. 4, fig. 4 is a schematic diagram of a thermomigration method of a cloud game according to an embodiment of the present application. The operation information of the cloud game server 1 includes the number of cloud game instances (cloud game instance 111, cloud game instance 121, and cloud game container 131) operated on the cloud game server 1 based on the containers (container 11, container 12, and container 13), that is, the number of cloud game instances operated on the cloud game server 1 is 3.

As an example, referring to fig. 4, the operation information of the cloud game server 2 includes the number of cloud game instances (cloud game instances 221 and cloud game instances 231) operated on the cloud game server 2 based on the containers (containers 22 and 23), that is, the number of cloud game instances operated on the cloud game server 2 is 2.

In this way, the number of cloud game instances on each cloud game server is acquired by acquiring the operation information of each cloud game server in the plurality of cloud game servers, so that the number of cloud game instances on each cloud game server is convenient to accurately determine the server to be migrated and the target server based on the number of cloud game instances operated on each cloud game server, and the accuracy of the determined server to be migrated and the target server is effectively improved.

In step 102, a server to be migrated and a corresponding target server to be migrated are determined from a plurality of cloud game servers based on the number of cloud game instances running on each cloud game server.

In some embodiments, the server to be migrated refers to a cloud game server where the cloud game instance being executed needs to be migrated, and the target server refers to a cloud game server where the cloud game instance being executed by the server to be migrated needs to be received.

In some embodiments, the cloud game migration is achieved by performing cloud game migration on a cloud game instance running on a server to be migrated, and migrating the cloud game instance to a corresponding target server.

In some embodiments, cloud game migration refers to a process of migrating a cloud game instance running on a server to be migrated to a target server, so that running loss of the server to be migrated is released, meanwhile, the cloud game instance running on the server to be migrated is guaranteed, the cloud game instance can be migrated to the target server to continue running, a target terminal connected with the server to be migrated and used for running a cloud game can be guaranteed not to be influenced by the migration of the cloud game instance, intelligent regulation and control of a running space of the cloud game server are realized while no perception of the target terminal used for running the cloud game is realized, running cost of the cloud game server is effectively saved, and running efficiency is improved.

In some embodiments, referring to fig. 7, fig. 7 is a flowchart of a method for thermomigration of a cloud game according to an embodiment of the present application, and step 102 shown in fig. 7 may be implemented by executing the following steps 1021 to 1023.

In step 1021, the cloud game servers for which the number of operating cloud game instances is less than a first threshold are determined to be servers to be migrated, and a first number of servers to be migrated is obtained.

In some embodiments, the first threshold may be specifically set according to a number of bearers of the cloud game server, where the first threshold is much smaller than the number of bearers of the cloud game server (e.g., the first threshold is smaller than half of the number of bearers of the cloud game server), and the number of bearers of the cloud game server is the maximum number of cloud game instances that the cloud game server can carry.

In some embodiments, the number of bearers of the cloud game server is equal to the number of containers in the cloud game server.

As an example, when the number of bearers of the cloud game server is 10, the first threshold of the cloud game server may be set to 3.

As an example, referring to fig. 5, fig. 5 is a schematic diagram of a thermomigration method of a cloud game provided by an embodiment of the present application, when a first threshold of a cloud game server is set to 3, the number of cloud game instances operated by a cloud game server 1 is 3 (i.e., cloud game instance 111, cloud game instance 121, and cloud game instance 131), the number of cloud game instances operated by a cloud game server 2 is 2 (i.e., cloud game instance 221 and cloud game instance 231), the number of cloud game instances operated by a cloud game server 3 is 1 (i.e., cloud game instance 311), the number of cloud game instances operated by a cloud game server 4 is 3 (i.e., cloud game instance 431, cloud game instance 411, and cloud game instance), i.e., the number of cloud game instances operated by a cloud game server 2 and a cloud game server 3 is smaller than the first threshold 3, and the cloud game server 2 and the cloud game server 3 are determined as servers.

In some embodiments, the cloud game server is determined to be the server to be migrated when the number of cloud game instances run by the cloud game server is less than a first threshold.

In some embodiments, the first number of servers to be migrated may be at least one (e.g., at least two).

It can be understood that the number of cloud game instances operated by the cloud game server is smaller than the first threshold, the first number of cloud game instances operated by the cloud game server is characterized to be far smaller than the bearing number of the cloud game server, namely, the cloud game server has larger container space redundancy, so that the cloud game server can be determined as the server to be migrated, the cloud game migration is conveniently carried out on the cloud game instances operated by the server to be migrated subsequently, the intelligent regulation and control of the operation space of the cloud game server are realized while no perception of a target terminal for operating the cloud game is realized, the operation cost of the cloud game server is effectively saved, and the operation efficiency is improved.

In step 1022, the number of cloud game instances running is greater than or equal to a first threshold and less than a second threshold is determined as a candidate cloud game server and a second number of candidate cloud game servers is obtained.

As an example, referring to fig. 5, when the first threshold of the cloud game server is set to 3, and the number of bearers of the cloud game server is 11, the corresponding second threshold may be 8, the number of cloud game instances operated by the cloud game server 1 is 3 (i.e., the cloud game instance 111, the cloud instance 121, and the cloud game instance 131), the number of cloud game instances operated by the cloud game server 2 is 2 (i.e., the cloud game instance 221 and the cloud game instance 231), the number of cloud game instances operated by the cloud game server 3 is 1 (i.e., the cloud game instance 311), the number of cloud game instances operated by the cloud game server 4 is 3 (i.e., the cloud game instance 431, the cloud game instance 411, and the cloud game instance 421), the number of cloud game instances operated by the cloud game server 5 is 4 (i.e., the cloud instance 511, the cloud instance 521, the cloud instance 531, and the cloud instance 231), the number of cloud game instances operated by the cloud game server 3 is 1 (i.e., the cloud game instance 631), the number of cloud game instances is determined by the first threshold, the cloud server 4 is equal to the first threshold, and the number of cloud game instances is equal to the second threshold is equal to the threshold of the first threshold, the cloud server 4, and the number of cloud game instances is determined by the first threshold is equal to the threshold.

In some embodiments, the second threshold is a difference between a number of bearers of the cloud gaming server and the first threshold, the number of bearers being a maximum number of cloud game instances that the cloud gaming server can handle.

In some embodiments, the number of cloud game instances run by the candidate cloud game server is greater than or equal to a first threshold and less than a second threshold.

In some embodiments, the second number of candidate cloud game servers may be at least one (e.g., at least two).

Therefore, the candidate cloud game server is accurately determined from the cloud game servers according to the number of the cloud game instances to be operated, so that the cloud game instances to be operated by the server to be migrated can be migrated to the target server to continue to be operated, the target terminal for operating the cloud game is not perceived, intelligent regulation and control of the operation space of the cloud game server are realized, the operation cost of the cloud game server is effectively saved, and the operation efficiency is improved.

In step 1023, a target server corresponding to the server to be migrated is determined from the plurality of cloud game servers based on the first number and the second number.

In some embodiments, step 1023 above may be implemented by: when the first quantity is smaller than the second quantity, selecting the first quantity of candidate cloud game servers from the second quantity of candidate cloud game servers as target servers corresponding to the servers to be migrated; when the first quantity is equal to the second quantity, determining each candidate cloud game server as a target server corresponding to the server to be migrated; and when the first quantity is larger than the second quantity, acquiring the total quantity of cloud game instances running on each server to be migrated as the first quantity and the total quantity of cloud game instances running in each candidate cloud game server as the second quantity, and determining a target server corresponding to the server to be migrated based on the first quantity and the second quantity.

As an example, referring to fig. 5, the second number of candidate cloud game servers is 2 (i.e., cloud game server 1 and cloud game server 4), the first number of cloud game servers to be migrated is 2 (i.e., cloud game server 2 and cloud game server 3), and when the first number is equal to the second number, each candidate cloud game server (cloud game server 1 and cloud game server 4) is determined as a target server corresponding to the server to be migrated (cloud game server 2 and cloud game server 3), and since the number of cloud game instances running on cloud game server 1 and cloud game server 4 is the same and the number of bearers of cloud game server 1 and cloud game server 4 is the same, the free number of cloud game servers 1 and cloud game server 4 is the same, and therefore, the target servers corresponding to the server to be migrated (cloud server 2) may be cloud game server 1 or cloud game server 4, and the target servers corresponding to cloud game server 1 and cloud game server 4 may be cloud game server 4. Referring to fig. 5, fig. 5 schematically sets a target server corresponding to a server to be migrated (cloud game server 2) as a cloud game server 1, and sets a target server corresponding to a server to be migrated (cloud game server 3) as a cloud game server 4.

In some embodiments, when the first number is less than the second number, selecting the first number of candidate cloud game servers from the second number of candidate cloud game servers as target servers corresponding to the servers to be migrated. When the first number of cloud game servers to be migrated is smaller than the second number of cloud game servers Yu Houxuan, then it is described that all candidate cloud game servers are not required to be determined as target servers, and only the first number of candidate cloud game servers are required to be selected from the second number of candidate cloud game servers to be used as target servers corresponding to the servers to be migrated.

As an example, referring to fig. 6, fig. 6 is a schematic diagram of a thermomigration method of a cloud game provided by the embodiment of the present application, when the first threshold of the cloud game server is set to 3, the corresponding second threshold may be 8 when the number of bearers of the cloud game server is 11, the number of cloud game instances operated by the cloud game server 1 is 3 (i.e., the cloud game instance 111, the cloud game instance 121, and the cloud game instance 131), the number of cloud game instances operated by the cloud game server 2 is 2 (i.e., the cloud game instance 221 and the cloud game instance 231), the number of cloud game instances operated by the cloud game server 3 is 3 (i.e., the cloud game instance 311, the cloud game instance 321, and the cloud game instance 331), the number of cloud game instances operated by the cloud game server 4 is 3 (i.e., the cloud instance 431, the cloud instance 411, and the cloud instance 421), the number of cloud game instances operated by the cloud game server 5 is 2 (i.e., the cloud game instance 221 and the cloud instance 231), the number of cloud game instances operated by the cloud server 3 (i.e., the cloud game instance 311, the cloud instance 321, and the cloud instance 331), the number of cloud game instances operated by the cloud server 4 is equal to the first threshold is equal to the threshold, and the number of cloud game instances is equal to the first threshold of the cloud server 1, the cloud server is equal to the threshold of the number of cloud game instances 1, the cloud game instances is determined by the cloud server 4, and the number of the cloud server is equal to the cloud server 1 is the threshold is equal to the threshold is the threshold. The number of cloud game instances that the cloud game server 2 runs is smaller than a first threshold, and the cloud game server 2 is determined as a server to be migrated.

As an example, referring to fig. 6, when the first number (1) of servers to be migrated is smaller than the second number (2) of cloud game servers Yu Houxuan, from among the second number of candidate cloud game servers (i.e., cloud game server 1 and cloud game server 4), the first number (1) of candidate cloud game servers are selected as target servers corresponding to the servers to be migrated, and since the number of cloud game instances running in the cloud game server 1 and cloud game server 4 is the same, one can be arbitrarily selected from the cloud game server 1 and cloud game server 4 as a target server corresponding to the servers to be migrated (as cloud game server 2).

As an example, referring to fig. 6, fig. 6 schematically shows the cloud game server 1 as a target server corresponding to a server to be migrated (cloud game server 2).

In some embodiments, after the selecting the first number of candidate cloud game servers as the target servers corresponding to the servers to be migrated, when the first number is multiple (i.e. at least two), each target server may correspond to one server to be migrated, and the following processes may be sequentially performed for each server to be migrated in the first number of servers to be migrated: acquiring the idle quantity of each unmatched target server, wherein the idle quantity is equal to the bearing quantity of the target server minus the quantity of cloud game instances running on the target server; subtracting the number of cloud game instances running on the server to be migrated from the idle number of each target server to obtain a subtraction value corresponding to the idle number of each target server; and determining the target server corresponding to the minimum subtraction value as a target server matched with the server to be migrated, and determining the matched target server as a matched target server.

In some embodiments, each target server corresponds to at least one server to be migrated, i.e., one target server may correspond to at least one server to be migrated. After the first number of candidate cloud game servers are selected as the target servers corresponding to the servers to be migrated, when the first number is multiple (i.e., at least two), the following processes may be sequentially performed for each server to be migrated in the first number of servers to be migrated: acquiring the idle quantity of each target server, wherein the idle quantity is equal to the bearing quantity of the target server minus the quantity of cloud game instances running on the target server; subtracting the number of cloud game instances running on the server to be migrated from the idle number of each target server to obtain a subtraction value corresponding to the idle number of each target server; and determining the target server corresponding to the minimum subtraction value as a target server matched with the server to be migrated, and updating the idle number of the matched target server to be the idle number minus the number of cloud game instances running on the server to be migrated.

In some embodiments, after determining each candidate cloud game server as a target server corresponding to the server to be migrated when the first number is equal to the second number, when the first number is multiple (i.e., at least two), the following processing may be sequentially performed for each server to be migrated in the first number of servers to be migrated: acquiring the idle quantity of each target server, wherein the idle quantity is equal to the bearing quantity of the target server minus the quantity of cloud game instances running on the target server; subtracting the number of cloud game instances running on the server to be migrated from the idle number of each target server to obtain a subtraction value corresponding to the idle number of each target server; and determining the target server corresponding to the minimum subtraction value as a target server matched with the server to be migrated, and updating the idle number of the matched target server to be the idle number minus the number of cloud game instances running on the server to be migrated.

In some embodiments, after determining each candidate cloud game server as a target server corresponding to a server to be migrated when the first number is equal to the second number, when the first number is multiple (i.e., at least two), each target server may correspond to one server to be migrated, and the following processes may be sequentially performed for each server to be migrated in the first number of servers to be migrated: acquiring the idle quantity of each unmatched target server, wherein the idle quantity is equal to the bearing quantity of the target server minus the quantity of cloud game instances running on the target server; subtracting the number of cloud game instances running on the server to be migrated from the idle number of each target server to obtain a subtraction value corresponding to the idle number of each target server; and determining the target server corresponding to the minimum subtraction value as a target server matched with the server to be migrated, and determining the matched target server as a matched target server.

In some embodiments, the determining the target server corresponding to the server to be migrated based on the first total number and the second total number may be implemented as follows: when the first total number is greater than the second total number, determining each candidate cloud game server as a first target server, acquiring a difference value between the first total number and the second total number, and determining a second target server from a plurality of cloud game servers based on the difference value, wherein the idle number of the second target server is greater than or equal to the difference value, the idle number is the number of cloud game instances running on the second target server subtracted from the bearing number, and the bearing number is the maximum number of cloud game instances which can be borne by the second target server; determining a first target server and a second target server as target servers corresponding to the servers to be migrated; and when the first total number is smaller than or equal to the second total number, determining each candidate cloud game server as a target server corresponding to the server to be migrated.

In some embodiments, when the total number of cloud game instances running on each of the cloud game servers to be migrated is greater than the total number of cloud game instances running in each of the candidate cloud game servers, which indicates that the free capacity of the candidate cloud game servers cannot meet the requirements to be migrated of the servers to be migrated, then each of the candidate cloud game servers may be determined as a first target server (i.e., a portion of the target servers), and then a second target server (i.e., a target server other than the first target server among the plurality of target servers) is determined from the plurality of cloud game servers, so as to meet the migration requirements of the servers to be migrated.

In some embodiments, the determining, based on the difference, the second target server from the plurality of cloud game servers may be implemented as follows: a reference cloud game server is determined from a plurality of cloud game servers, wherein the reference cloud game server is a cloud game server other than the first target server. And determining the cloud game servers with the free number larger than or equal to the difference value from the reference cloud game servers, and determining the cloud game servers with the free number larger than or equal to the difference value as a second target server.

In some embodiments, when the first total number is less than or equal to the second total number, indicating that the free capacity of the candidate cloud game servers can already meet the requirement of waiting for migration of the server to be migrated, then each candidate cloud game server is determined to be the target server corresponding to the server to be migrated, and in this case, the first number of the servers to be migrated is greater than the second number of the candidate cloud game servers, and the server to be migrated corresponds to at least one candidate cloud game server (i.e., the candidate cloud game server with a greater free number corresponds to a plurality of servers to be migrated).

In this way, the number of cloud game instances operated on each cloud game server is used for determining the servers to be migrated and the candidate cloud game servers, the first number of the servers to be migrated and the second number of the candidate cloud game servers, and based on the first number, the second number and the number of the cloud game instances operated on each cloud game server, a corresponding target server is determined for each server to be migrated, so that in the process of migrating the follow-up cloud games, the cloud game instances operated on each server to be migrated can be accurately migrated to the most suitable target server to continue to operate, intelligent regulation and control of the operation space of the cloud game servers are realized, the operation cost of the cloud game servers is effectively saved, and the operation efficiency is improved.

In some embodiments, after step 102 described above, the connection between the target server and the target terminal may be established by: acquiring terminal information corresponding to cloud game instances running on a server to be migrated, wherein the terminal information indicates a target terminal for displaying the cloud game; and sending the terminal information to the target server so that the target server establishes communication connection with the target terminal based on the terminal information.

In some embodiments, the obtaining terminal information corresponding to the cloud game instance running on the server to be migrated, and sending the terminal information to the target server, so that the target server establishes communication connection with the target terminal based on the terminal information may be implemented in the following manner: the following processes are respectively executed for each server to be migrated: terminal information corresponding to cloud game instances running on the server to be migrated is obtained, and the terminal information is sent to a target server corresponding to the server to be migrated, so that the target server corresponding to the server to be migrated establishes communication connection with a target terminal based on the terminal information.

As an example, referring to fig. 13, fig. 13 is a schematic diagram of a thermomigration method of a cloud game provided by an embodiment of the present application, where a game server obtains terminal information (terminal information corresponding to a cloud game client) corresponding to a cloud game instance running on a server to be migrated (cloud game server 1), the terminal information indicating a target terminal for displaying the cloud game (a terminal running the cloud game client); the terminal information is transmitted to the target server (cloud game server 2) so that the target server (cloud game server 2) establishes a communication connection with the target terminal (terminal running the cloud game client) based on the terminal information.

After the server to be migrated and the target server are determined, terminal information corresponding to cloud game instances operated on the server to be migrated is obtained, and the terminal information is sent to the target server corresponding to the server to be migrated, so that the target server corresponding to the server to be migrated is in communication connection with the target terminal based on the terminal information, the cloud game video stream generated by rendering of the target server is conveniently sent to the target terminal for display, the target terminal connected with the server to be migrated and used for operating the cloud game can be prevented from being influenced by cloud game instance migration, intelligent regulation and control of the operation space of the cloud game server are realized while the target terminal for operating the cloud game is not perceived, the operation cost of the cloud game server is effectively saved, and the operation efficiency is improved.

In step 103, a byte stream of each cloud game instance running on the server to be migrated is obtained from the server to be migrated, and the byte stream is obtained by serializing the corresponding cloud game instance.

In some embodiments, byte stream refers to a continuous stream of binary byte arrays that do not contain boundaries.

In some embodiments, the byte stream of the cloud game instance refers to a binary byte array corresponding to the cloud game instance, the binary byte array corresponding to each game time is obtained by serializing the cloud game instance at each game time, and the binary byte arrays corresponding to each game time are ordered according to the sequence of the game time, so as to obtain the byte stream of the cloud game instance.

In some embodiments, from the server to be migrated, obtaining the byte stream of each cloud game instance running on the server to be migrated may be achieved by: mode 1 (corresponding to the following steps 1031 to 1032): the byte stream of each cloud game instance can be read through the server to be migrated, and then the byte stream of each cloud game instance is obtained from the server to be migrated; mode 2 (corresponding to steps 1033 to 1034 below): and directly acquiring page table information of the image processor corresponding to each container sent by the server to be migrated without reading byte streams of each cloud game instance by the server to be migrated, and then reading the byte streams. Through the two modes, byte streams of each cloud game instance running on the server to be migrated can be accurately obtained, so that the obtained byte streams of each cloud game instance running on the server to be migrated can be migrated to the target server conveniently, and therefore accurate migration of the cloud game instance is achieved, and the two modes are described below in connection with the steps 1031 to 1034.

In some embodiments, the containers are in a one-to-one correspondence with cloud game instances, each container corresponds to one graphics processor, referring to fig. 8, fig. 8 is a schematic flow chart of a method for thermomigration of a cloud game according to an embodiment of the present application, and step 103 shown in fig. 8 may be implemented by executing the following steps 1031 to 1032.

In step 1031, a byte stream obtaining request is sent to the server to be migrated, so that the server to be migrated obtains page table information of the graphics processor corresponding to each container, and reads the byte stream of each cloud game instance from the video memory space of the corresponding graphics processor based on each page table information.

In some embodiments, a byte stream fetch request is used to cause a server to be migrated to fetch a byte stream for each cloud instance.

In some embodiments, the byte stream refers to a continuous stream of binary byte arrays without boundaries, the byte stream of the cloud game instance refers to a binary byte array corresponding to the cloud game instance, the binary byte array corresponding to each game time is obtained by serializing the cloud game instance at each game time, and the binary byte arrays corresponding to each game time are ordered according to the sequence of the game time, so as to obtain the byte stream of the cloud game instance.

In some embodiments, the containers correspond to cloud game instances one by one, each container corresponds to a graphics processor, and the server to be migrated may perform the following processing for each container: and acquiring page table information of the graphics processor corresponding to the container, and reading the byte stream of the cloud game instance corresponding to the container from the video memory space of the graphics processor corresponding to the container based on the page table information.

In some embodiments, the page table information of the graphics processor includes a mapping relationship between each video memory space of the graphics processor and the byte stream of the cloud game instance, the mapping relationship between each video memory space and the byte stream of the cloud game instance characterizing whether the byte stream of the cloud game instance is stored in the video memory space.

It may be appreciated that the graphics processor includes a plurality of video memory spaces, where the plurality of video memory spaces includes a first video memory space for storing a byte stream of the cloud game instance and a second video memory space for storing data other than the byte stream of the cloud game instance, and then the mapping relationship may include a first mapping relationship corresponding to the first video memory space and a second mapping relationship corresponding to the second video memory space, where the first mapping relationship corresponding to the first video memory space indicates that the byte stream of the cloud game instance is stored in the first video memory space, and the second mapping relationship corresponding to the second video memory space indicates that the byte stream of the cloud game instance is not stored in the second video memory space. And obtaining mapping relations corresponding to each video memory space from page table information of a graphics processor corresponding to the container, determining a first mapping relation from the mapping relations corresponding to each video memory space, and reading byte streams of cloud game instances corresponding to the container from the video memory space corresponding to the first mapping relation.

As such, because the cloud game instances running on the cloud game server are based on container running (containers do not have hardware virtualization), i.e., there are different possibilities for the hardware environment between different containers, the containers running on the server to be migrated and the containers running on the target server may differ in the corresponding graphics processors. Because the containers running on the target server and the containers running on the server to be migrated may differ from each other, and thus the corresponding video memory space may also differ, if the page table information of the graphics processor corresponding to each container running on the server to be migrated is directly obtained, the page table information is migrated to the target server, and even if the page table information is migrated to the target server due to the difference of the video memory space, the byte stream of the cloud game instance read on the target server may not be the byte stream of the original cloud game instance on the server to be migrated based on the page table information migrated, so that accurate migration of the cloud game instance cannot be realized. Therefore, in the embodiment of the application, the byte stream of each cloud game instance is directly read at the server to be migrated, and the byte stream of the cloud game instance read at the server to be migrated is directly migrated to the target server, so that the problem of inaccurate cloud game instance migration caused by migrating page table information of the graphic processor is avoided, the accuracy of the byte stream of the cloud game instance migrated to the target server is ensured, and the accurate migration of the cloud game instance is realized.

In step 1032, a byte stream for each cloud instance sent by the server to be migrated is received.

Therefore, the byte stream of each cloud game instance is read through the server to be migrated, and the byte stream of each cloud game instance sent by the server to be migrated is received, so that the accurate acquisition of the byte stream of each cloud game instance is realized, the byte stream of each cloud game instance is conveniently and accurately migrated to the target server, the intelligent regulation and control of the running space of the cloud game server is realized, the running cost of the cloud game server is effectively saved, and the running efficiency is improved.

In some embodiments, the containers are in a one-to-one correspondence with cloud game instances, each container corresponds to one graphics processor, referring to fig. 9, fig. 9 is a schematic flow chart of a method for thermomigration of a cloud game according to an embodiment of the present application, and step 103 shown in fig. 9 may be implemented by executing the following steps 1033 to 1034.

In step 1033, a byte stream fetch request is sent to the server to be migrated.

In step 1034, receiving page table information of an image processor corresponding to each container sent by the server to be migrated; based on each page table information, a byte stream of each cloud game instance is read from a video memory space of a corresponding image processor.

In some embodiments, the containers correspond to cloud game instances one-to-one, each container corresponds to a graphics processor, and the foregoing step 1034 may be performed separately for each container: and acquiring page table information of the graphics processor corresponding to the container, and reading the byte stream of the cloud game instance corresponding to the container from the video memory space of the graphics processor corresponding to the container based on the page table information.

As such, because the cloud game instances running on the cloud game server are based on container running (containers do not have hardware virtualization), i.e., there are different possibilities for the hardware environment between different containers, the containers running on the server to be migrated and the containers running on the target server may differ in the corresponding graphics processors. Because the containers running on the target server and the containers running on the server to be migrated may differ from each other, and thus the corresponding video memory space may also differ, if the page table information of the graphics processor corresponding to each container running on the server to be migrated is directly obtained, the page table information is migrated to the target server, and even if the page table information is migrated to the target server due to the difference of the video memory space, the byte stream of the cloud game instance read on the target server may not be the byte stream of the original cloud game instance on the server to be migrated based on the page table information migrated, so that accurate migration of the cloud game instance cannot be realized. Therefore, in the embodiment of the application, the byte stream of each cloud game instance is not read through the server to be migrated, the page table information of the image processor corresponding to each container sent by the server to be migrated is directly obtained, then the byte stream is read, and the read byte stream of the cloud game instance is directly migrated to the target server, so that the problem of inaccurate cloud game instance migration caused by migrating the page table information of the image processor is avoided, the accuracy of the byte stream of the cloud game instance migrated to the target server is ensured, and the accurate migration of the cloud game instance is realized.

Thus, the page table information of the image processor corresponding to each container sent by the server to be migrated is received, and based on the page table information, the byte stream of each cloud game instance is read from the video memory space of the corresponding image processor, so that the byte stream of each cloud game instance is accurately acquired, the byte stream of each cloud game instance is accurately migrated to the target server in the follow-up process, the intelligent regulation and control of the running space of the cloud game server are realized, the running cost of the cloud game server is effectively saved, and the running efficiency is improved.

In some embodiments, the byte stream of each cloud game instance running on the server to be migrated may also be sequentially acquired, and a specific implementation of sequentially acquiring the byte stream is described below.

In some embodiments, referring to fig. 10, fig. 10 is a flowchart of a method for thermomigration of a cloud game according to an embodiment of the present application, and step 103 shown in fig. 10 may be implemented by executing the following steps 1035 to 1037 for each server to be migrated.

In step 1035, the number of objects corresponding to each cloud game instance running on the server to be migrated is obtained, where the number of objects is the number of virtual objects in the virtual scene corresponding to the cloud game instance.

In some embodiments, the virtual scene is a scene displayed when the game program runs on the terminal device, and the virtual scene may include sky, land, sea, etc., and the land may include environmental elements such as desert, city, etc., and virtual objects such as virtual characters, etc.

As an example, the number of objects corresponding to the cloud game instance 21 is 10, the number of objects corresponding to the cloud game instance 22 is 12, the number of objects corresponding to the cloud game instance 23 is 8, and the number of objects corresponding to the cloud game instance 24 is 6.

In step 1036, the cloud game instances running on the server to be migrated are ordered in order of the number of objects from small to large, resulting in a cloud game instance queue.

In some embodiments, the cloud game instance queue refers to a queue formed by arranging cloud game instances in order of small number of objects.

As an example, the number of objects corresponding to the cloud game instance 21 is 10, the number of objects corresponding to the cloud game instance 22 is 12, the number of objects corresponding to the cloud game instance 23 is 8, and the number of objects corresponding to the cloud game instance 24 is 6. The cloud game instances running on the server to be migrated are ordered according to the order of the number of objects from small to large, and a cloud game instance queue is obtained, wherein the cloud game instance queue can be { cloud game instance 24, cloud game instance 23, cloud game instance 21, cloud game instance 22}.

In step 1037, from the top of the cloud game instance queue, byte streams for each cloud game instance in the cloud game instance queue are sequentially obtained.

In some embodiments, the scheduling server sequentially obtains byte streams of each cloud game instance in the cloud game instance queue from the queue head of the cloud game instance queue, and sequentially sends the obtained byte streams of each cloud game instance to the target server in real time, so that the thermomigration of the cloud game instances is completed one by one, that is, the byte streams of each cloud game instance are sequentially sent to the target server according to the obtaining sequence of the byte streams of each cloud game instance, and the cloud game instance with smaller object number can migrate more quickly because the number of objects corresponding to the cloud game instance is proportional to the transmission speed of the cloud game instance.

As an example, from the head of the cloud game instance queue { cloud game instance 24, cloud game instance 23, cloud game instance 21, cloud game instance 22}, the byte stream of the cloud game instance queue { cloud game instance 24, cloud game instance 23, cloud game instance 21, cloud game instance 22}, cloud game instance 24, cloud game instance 23, cloud game instance 21, cloud game instance 22} is sequentially acquired.

Therefore, the byte streams of the cloud game instances are sequentially obtained according to the sequence from small to large in the number of the objects corresponding to the cloud game instances, and the cloud game instances with smaller object numbers can be quickly migrated due to the fact that the number of the objects corresponding to the cloud game instances is in direct proportion to the transmission speed of the cloud game instances, so that the running space of the server to be migrated can be quickly released, the regulation speed of the running space of the cloud game server is realized, the running cost of the cloud game server is effectively saved, and the running efficiency is improved.

In some embodiments, referring to fig. 11, fig. 11 is a flowchart of a method for thermomigration of a cloud game according to an embodiment of the present application, and step 103 shown in fig. 11 may be implemented by executing the following steps 1038 to 1039 for each cloud game instance running on a server to be migrated.

In step 1038, a dynamic virtual object and a static virtual object are determined from virtual objects included in a virtual scene corresponding to the cloud game instance.

In some embodiments, the dynamic virtual object is a virtual object in a moving state in a virtual scene, and the static virtual object is a virtual object in a static state in the virtual scene.

As an example, the dynamic virtual object may be a virtual character, a virtual animal, etc., and the static virtual object may be a virtual tree, a virtual building, etc.

In step 1039, obtaining byte streams corresponding to each static virtual object; and acquiring the byte stream corresponding to each dynamic virtual object in response to the completion of the acquisition of the byte stream corresponding to each static virtual object.

In some embodiments, the byte stream of the cloud game instance includes a byte stream corresponding to a static virtual object and a byte stream of a dynamic virtual object included in a virtual scene corresponding to the cloud game instance, and since the static virtual object does not change in position with time, the dynamic virtual object tends to change in position with time, and therefore, the byte stream corresponding to the static virtual object that does not change with time can be acquired first, and then the byte stream corresponding to the dynamic virtual object that changes with time can be acquired, so that the real-time updating of the byte stream corresponding to the dynamic virtual object is ensured by using the time difference of the byte stream corresponding to the static virtual object when acquiring, and the accuracy and the real-time performance of the byte stream of the acquired cloud game instance are ensured. In some embodiments, a byte stream corresponding to a non-virtual object, such as a virtual map, in a virtual scene may also be obtained.

In some embodiments, the byte stream of the cloud game instance includes a byte stream corresponding to a static virtual object included in a virtual scene corresponding to the cloud game instance, a byte stream of a dynamic virtual object, and a byte stream corresponding to a non-virtual object such as a virtual map in the virtual scene. Therefore, before the step 1039 or after the step 1039, or while the step 1039 is executed, the byte stream corresponding to the non-virtual objects such as the virtual map in the virtual scene is acquired, so that the acquisition integrity of the byte stream of the cloud game instance is effectively ensured.

In some embodiments, the obtaining the byte stream corresponding to each dynamic virtual object may be implemented as follows: acquiring acquisition priorities of the dynamic virtual objects, wherein the acquisition priorities are inversely related to the moving frequency of the dynamic virtual objects, and the moving frequency represents the moving times of the dynamic virtual objects in the virtual scene in unit time; and sequentially acquiring byte streams corresponding to each dynamic virtual object according to the order of the acquisition priority from high to low.

In some embodiments, the frequency of movement of the dynamic virtual object characterizes the number of movements of the dynamic virtual object in the virtual scene within a unit time, for example, the frequency of movement of the dynamic virtual object is lower by 10 times within 1s, which characterizes the number of movements of the dynamic virtual object in the virtual scene to be lower, that is, the slower the change of the dynamic virtual object is, the closer to the static virtual object, the higher the acquisition priority of the corresponding dynamic virtual object is, that is, the higher the acquisition priority of the dynamic virtual object is, that is, the lower the movement frequency is, the more preferentially the dynamic virtual object is acquired, so that the real-time updating property of byte streams corresponding to the dynamic virtual object with higher movement frequency is ensured by using the time difference of byte streams corresponding to the dynamic virtual object with lower movement frequency when acquiring, and the accuracy and the real-time property of the byte streams corresponding to the obtained dynamic virtual objects are improved.

As an example, for dynamic virtual object 31, dynamic virtual object 32, dynamic virtual object 33, and dynamic virtual object 34, the frequency of movement of dynamic virtual object 31 is greater than the frequency of movement of dynamic virtual object 33, greater than the frequency of movement of dynamic virtual object 32, greater than the frequency of movement of dynamic virtual object 34; the corresponding acquisition priority of the dynamic virtual object 31 is smaller than the acquisition priority of the dynamic virtual object 33 and smaller than the acquisition priority of the dynamic virtual object 32 and smaller than the moving frequency of the dynamic virtual object 34, so that byte streams corresponding to the dynamic virtual object 34, the dynamic virtual object 32, the dynamic virtual object 33 and the dynamic virtual object 31 can be sequentially acquired according to the order of the acquisition priority from high to low, and the byte streams corresponding to the dynamic virtual object 34 can be acquired firstly because the moving frequency of the dynamic virtual object 34 is slowest, and the dynamic virtual object 32, the dynamic virtual object 33 and the dynamic virtual object 31 still move in the virtual scene according to the moving frequency respectively in the period of acquiring the byte streams corresponding to the dynamic virtual object 34, so that the byte streams corresponding to the dynamic virtual object 32, the dynamic virtual object 33 and the dynamic virtual object 31 which are acquired later are not influenced by the dynamic virtual object 34, and higher accuracy is maintained.

In this way, the acquisition priority of each dynamic virtual object inversely related to the moving frequency is determined according to the moving frequency of the dynamic virtual object, and byte streams corresponding to each dynamic virtual object are sequentially acquired according to the order of the acquisition priority from high to low, so that byte streams corresponding to dynamic virtual objects with lower moving frequency are preferentially acquired.

In step 104, the byte stream for each cloud instance is sent to a target server, which deserializes the byte stream to recreate each cloud instance.

In some embodiments, the deserialization is the reverse process of the serialization, the byte stream of the cloud game instance refers to the binary byte array corresponding to the cloud game instance, the cloud game instance corresponding to each game time is obtained by deserializing the binary byte array corresponding to the cloud game instance at each game time, and the binary byte array corresponding to each game time is ordered according to the sequence of the game time, so that each cloud game instance can be recreated.

In some embodiments, after receiving the byte stream of each cloud game instance, the target server deserializes the byte stream, renders each cloud game instance after creating each cloud game instance, obtains the video stream of each cloud game instance, and sends the video stream of each cloud game instance to a corresponding target terminal, so that the target terminal performs cloud game display, thereby ensuring that the target terminal connected with the server to be migrated for running the cloud game can not be influenced by the migration of the cloud game instance, realizing the intelligent regulation and control of the running space of the cloud game server while realizing no perception of the target terminal for running the cloud game, effectively saving the running cost of the cloud game server, and improving the running efficiency.

In some embodiments, the step 104 may be implemented as follows: and sequentially sending the byte streams of the cloud game instances to the target server according to the acquisition sequence of the byte streams of the cloud game instances.

In some embodiments, the byte stream of each cloud instance may be in the order of acquisition: and sequentially acquiring byte streams of each cloud game instance according to the sequence of the small to large number of objects corresponding to the cloud game instance. Then, the sending order of the byte streams of the respective cloud game instances may be: and sequentially sending the byte streams of each cloud game instance to the target server according to the sequence of the small to large number of objects corresponding to the cloud game instance.

In some embodiments, the step 104 may be implemented as follows: and sequentially sending byte streams corresponding to the dynamic virtual objects to the target server according to the acquisition sequence of the byte streams corresponding to the dynamic virtual objects.

In some embodiments, the acquisition sequence of the byte stream corresponding to each dynamic virtual object may be: sequentially acquiring byte streams corresponding to each dynamic virtual object according to the order of the acquisition priority from high to low; then, the sending sequence of the byte stream corresponding to each dynamic virtual object may be: and sequentially sending the byte streams corresponding to the dynamic virtual objects to the target server according to the order of the acquisition priority from high to low.

In some embodiments, after the above step 104, the connection between the server to be migrated and the target terminal may be disconnected as follows: responding to a migration completion message sent by a target server, and sending a disconnection instruction to a server to be migrated; the connection disconnection instruction is used for disconnecting the server to be migrated from a target terminal, and the target terminal is a terminal for displaying the cloud game.

In some embodiments, the migration completion message is used to indicate that the cloud game instance has been completely migrated to the target server, and is used to trigger the sending of the disconnection instruction.

As an example, referring to fig. 13, fig. 13 is a schematic diagram of a thermomigration method of a cloud game provided by an embodiment of the present application, in response to a migration completion message sent by a target server (cloud game server 2), a disconnection instruction is sent to a server to be migrated (cloud game server 1) to disconnect the server to be migrated (cloud game server 1) from a target terminal (cloud game client), the target terminal being a terminal for displaying a cloud game.

In this way, by acquiring the number of cloud game instances running on each cloud game server based on the container, determining a server to be migrated and a target server from a plurality of cloud game servers, acquiring byte streams of each cloud game instance running on the server to be migrated from the server to be migrated, transmitting the acquired byte streams to the target server, and deserializing the byte streams by the target server to recreate the cloud game instance migrated from the server to be migrated in the target server. Therefore, cloud game instances operated by the server to be migrated can be ensured to be continuously operated to the target server among cloud game servers operated based on the container, the target terminal connected with the server to be migrated for operating the cloud game can be ensured not to be influenced by the migration of the cloud game instances, the intelligent regulation and control of the operation space of the cloud game server is realized, the cloud game instances operated on the server to be migrated are effectively and intensively migrated to the target server, and therefore the operation space of the server to be migrated is released, the operation cost of the cloud game server is effectively saved, and the operation efficiency is improved.

In the following, an exemplary application of the embodiment of the present application in an application scenario of an actual cloud game will be described.

The cloud game is a game mode based on cloud computing, and in the running mode of the cloud game, all games run on a server side, and rendered game pictures are compressed and then transmitted to a client side through a network. At the client, the user's game device does not need any high-end processor and graphics card, but only needs basic video decompression capability.

In the application scenario of cloud gaming, the game runs in a container of a cloud game server. When it is required to thermally migrate a container from one server to another, the conventional container thermal migration technique can only synchronize the state of the process, memory, network, etc. of the container to the other server, but cannot synchronize the state of the graphics processor to the other server.

The embodiment of the application does not need to directly transfer the state of the graphic processor, but uses the functions of object serialization and anti-serialization in the game engine to transmit the state of each object in the game to another server, and rebuilds the whole game state on the other server, thereby achieving the aim of thermomigration.

In some embodiments, referring to fig. 12, fig. 12 is a schematic diagram of a thermomigration method of a cloud game according to an embodiment of the present application. A plurality of cloud game containers (e.g., cloud game container 11 and cloud game container 12 as shown in fig. 12) may be run on the cloud game server, and during peak periods of cloud game operation, the cloud game containers on the cloud game server are substantially in use, and as cloud game users continue to exit, only a small number of containers may be still in use on one cloud game server. According to the embodiment of the application, the cloud game containers on the cloud game server can be thermally migrated, the scattered cloud game containers are concentrated on some cloud game servers under the condition that the user experience is not affected, and the idle cloud game servers are closed to help save the expenditure of the server, maintain and update the server and the like.

In some embodiments, the game engine generally has a serialization and deserialization function of the objects, for example, a fantasy engine (Unreal), in which all objects inherit from the base class (UObject) of the object, such as player characters, non-player characters (NPCs), maps, etc., all support the serialization and deserialization functions, and the objects can be converted into byte streams, so that the object states can be stored in files or transmitted over a network, so that the objects can be recreated when needed. The server of the network game always keeps the state information of all objects in the game, when migration starts, a new game instance is started on the target server, meanwhile, the migrated player information is used for logging in, then the game server starts to synchronize the current game state of the user to the new game instance, after the state synchronization is completed, the rendering picture of the new game instance can be the same as the picture of the original game instance, then the cloud game client end disconnects the original cloud game instance and establishes connection with the new cloud game instance, and a video stream picture of the new instance is obtained, so that migration is completed.

In some embodiments, referring to fig. 13, fig. 13 is a schematic diagram of a thermomigration method of a cloud game according to an embodiment of the present application. When migration starts, a new game instance is started on the target server (i.e., cloud game server 2 shown in fig. 13), at the same time, in cloud game server 2, login is performed with the migrated player information (i.e., player information of cloud game server 1), then the game server (i.e., cloud game server 2) starts synchronizing the current game state of the user with the new game instance, after the state synchronization is completed, at this time, the new game instance rendering screen (new game instance rendering screen on cloud game server 2) can be made the same as the original game instance screen (old game instance on cloud game server 1), and then the cloud game client disconnects from the original cloud game instance (i.e., cloud game client disconnects from cloud game server 1) and establishes connection with the new game instance (cloud game client and cloud game server 2), so as to obtain a video stream screen of the new instance, thereby completing migration.

In some embodiments, referring to fig. 14, fig. 14 is a flowchart of a method for thermomigration of a cloud game according to an embodiment of the present application, where the method for thermomigration of a cloud game according to an embodiment of the present application may be implemented through steps 201 to 208 shown in fig. 14.

In step 201, the middlebox scheduler gathers user information for the old game instance.

As an example, when migration starts, the middle stage scheduler gathers user information of the game instance to be migrated, i.e. user information of the old game instance.

In step 202, the middlebox scheduler initiates a new game instance on the target server and connects to the game server.

In step 203, the middlebox scheduler logs in user information on the new game instance.

As an example, the middlebox dispatcher logs in user information on a new game instance that needs to be modified to support two connections for the same user, and the new game instance needs to inform the game server that this connection needs to synchronize the game state.

In step 204, the game server synchronizes the object state in this user game to the new game instance.

By way of example, the game server synchronizes the object state in this user game to the new game instance, the state synchronization being performed in an iterative fashion, since the migration is performed while the player is operating, the object state will always change, but after most of the state synchronization only the changed part is synchronized.

In step 205, it is determined whether there is an unsynchronized object, and when there is an unsynchronized object, step 204 is performed.

In step 206, when there are no unsynchronized objects, a new game instance enters the game scene to begin rendering.

As an example, when synchronization is completed, the new game instance enters the actual game scene to start rendering the game screen, and at this time, the new game instance rendering screen can be the same as the original game instance screen.

In step 207, the mid-table scheduler notifies the cloud game client to connect with the new game instance.

As an example, the middle platform scheduler notifies the cloud game client to connect the new game instance, and the cloud game client disconnects the original cloud game instance and establishes connection with the new cloud game instance to obtain a video stream picture of the new instance, thereby completing migration.

In step 208, the old game instance is closed.

As an example, the middle stage scheduler closes the old game instance, completing the migration.

According to the embodiment of the application, the container on the cloud game server can be thermally migrated, the scattered cloud game containers are concentrated on certain servers under the condition that users are not influenced, and the idle servers are closed to help to save the expenditure of the servers, maintain and update the servers and the like.
