Description

  The present invention relates to a server mirroring method and system, and more particularly, to a method and system for mirroring channel information generated in a specific server to another server.

  The number of Internet users is continually increasing, which makes server load one of the most fundamental problems of Internet services. In particular, in the case of a system in which a large number of users connect to a server, such as an online game service system and a chat service system, the problem of server load becomes more serious. As a general method for solving such a server load problem, there is a method of adding servers as the number of users increases.

  FIG. 1 is a diagram showing an example of a service providing system using a plurality of ordinary servers. When a single server cannot accommodate all the connections of users, as shown in FIG. 120 and 130 are used to provide Internet services.

  However, the conventional system that solves the server load problem through a plurality of servers has a problem in that the activity area of the user is limited to the server to which the user is connected. That is, the users 111 and 112 connected to the first server 110 cannot participate in the channel generated in the second server 120 and can monitor the status of the channel generated in the second server 120. There wasn't.

  Hereinafter, the above problems will be described in more detail by taking an online game service system as an example.

  With the recent development of game technology, watching games is becoming established as a culture, similar to sports. In particular, as users' interest in watching games in strategic simulation games such as Go and Starcraft has increased, watching games has become as important as gameplay, and it has become a new element for game relaying. A system has been developed.

  Initially, a method of shooting and broadcasting a game situation with a camera was mainly used. However, according to this method, there is a limit that a game is relayed only to TV viewers. A system that can watch games through is required.

  In a game relay system in which a game can be watched through a conventional computer, the load on the server is the biggest problem. When a large number of users connect to a game server for watching a game, there is a problem that a game watching service is not provided to a certain number of users due to the server capacity limit.

  FIG. 2 is a diagram showing an example of a normal game relay system.

  In the case of an online game service in which a large number of users are connected, the user selects one of the plurality of servers 210, 220, and 230, and performs game play or game watching on the selected server.

  For example, when the user connects to the first game server 210, the user can communicate with the users connected to the first game server 210, and only the game room generated in the first game server 210 is available. It was possible to play games or watch games.

  In other words, the user connected to the first game server 210 cannot participate in the game room generated in the second game server 220, and the game situation progressed in the game room generated in the second server 220 is displayed. I couldn't even watch it.

  Therefore, for example, when a game is played between professional players at the first game server 210 and a specific relay person is explaining the game situation, the use connected to the second game server 220 and the third game server 230 Those who could not watch the game situation progressed on the first game server 210 and could not hear the explanation of the relay person.

  In order to solve the above problem, the first game server 210 can transmit the game progress status in the first game server 210 to the second game server 220 and the third game server 230. In this case, , Traffic will increase rapidly. As a result, it is necessary to provide a control server for transmitting the game progress status, and there is a problem in that the control server is configured with very complicated logic.

  The above problems are not only problems in games but in all systems that provide services through independent channels.

  Hereinafter, a message routing server 340 according to a preferred embodiment of the present invention will be described. According to a preferred embodiment of the present invention, the message routing server 340 supports a function of managing a plurality of connections as one group.

  FIG. 5 is a diagram illustrating groups generated in the message routing server 340 according to an exemplary embodiment of the present invention.

  Referring to FIG. 5, a subscriber group 520 and a publisher group 510 are generated in the message routing server 340 according to an embodiment of the present invention, and the subscriber group 520 is a group to which a mirroring server that mirrors a channel of the publisher server belongs. The publisher group 510 is a group to which a publisher server that provides channel information to be mirrored belongs.

  For example, in FIG. 3, the first server 310 that functions as a publisher server is registered in the publisher group 510, and the second server 320 and the third server 330 that function as mirroring servers are registered in the subscriber group 520.

  The first to third servers 310, 320, and 330 connected to the message routing server 340 are set to participate in one of the publisher group 510 or the subscriber group 520 of the message routing server 340 when the server is started. The message routing server 340 joins the subscriber group 520 or the publisher group 510 at the request of each connected server.

  According to a preferred embodiment of the present invention, the first server 310, which is a publisher server, provides the message routing server 340 with information about the channel that is mirrored in a multicast manner. The first server 310, which is a publisher server, includes only information on messages transmitted to the subscriber group 520 to the message routing server 340, and provides channel information to the message routing server 340. That is, the message related to the channel information transmitted from the first server 310 to the message routing server 340 does not include the address information of the second server 320 and the third server 330 that mirrors the channel information, and the message is transmitted. Only the identification information of the subscriber group 520 is included.

  When the message routing server 340 receives a message transmitted from the first server 310 which is a publisher server to the subscriber group 520, the message routing server 340 transmits the message transmitted from the publisher server to all mirroring servers participating in the subscriber group 520. To do. That is, the message routing server 340 receives the message from the first server 310 and transmits the message to the second server 320 and the third server 330 that have joined the subscriber group 520.

  The message routing server 340 determines whether the message to be transmitted is a message transmitted to each server of the subscriber group 520 or a message transmitted to each server of the publisher group 510, and determines the received message. It only plays a role of transmitting to the server of the publisher group 510 or the server of the subscriber group 520, and does not perform analysis, determination and control procedures of received messages.

  Accordingly, the message routing server 340 can have a simpler configuration than the control server for exchanging information between existing servers, and the message can be more easily specified without having to specify the recipient of the message each time. Since it is transmitted in a simplified manner, message traffic is also reduced.

  The second server 320 and the third server 330, which are subscriber servers, receive channel-related messages transmitted from the first server 310, which is a publisher server, from the message routing server 340, analyze the messages, and perform channel mirroring.

  For example, when the message transmitted from the first server 310 is a message including channel generation information, the second server 320 and the third server 330 analyze the message and have the same conditions as the information included in the channel generation information. (Hereinafter, referred to as “mirroring channel”). If the message transmitted from the first server 310 is a message including the channel state change information, the second server 320 and the third server 330 analyze the message and set the mirroring channel to the same state as the channel of the first server. Change the state of.

  FIG. 15 is a conceptual diagram illustrating that a message of a publisher server is transmitted to each mirroring server belonging to a subscriber group through a message routing server.

  Referring to FIG. 15, the publisher server 1530 and the mirroring servers 1510 and 1520 participating in the publisher group 510 and the subscriber group 520 of the message routing server are connected to the message routing server through a socket.

  As shown in FIG. 15, when the publisher server 1530 attempts to transmit a message to each mirroring server 1510, 1520 that has joined the subscriber group 520, the publisher server 1530 sets the subscriber group 520 as a destination address. A message is transmitted by a multicast method.

  The message routing server transmits the message transmitted from the publisher server 1530 to each mirroring server 1510 and 1520 through a socket that is a connection medium with each mirroring server 1510 and 1520 belonging to the subscriber group 520.

  On the other hand, in the case of a game relay system using server mirroring, the first, second, and third servers 310, 320, and 330 in FIG. 5 are the first, second, and third game servers 410, 420, and 430 in FIG. The channel generation information and the channel state change information mean game room generation information and game progress information.

  That is, when the message routing server 440 receives a message transmitted from the first game server 410 that is a publisher game server to the subscriber group 520, the message routing server 440 sends all the mirroring game servers that have joined the subscriber group 520 from the publisher game server. Transmit the transmitted message. That is, the message routing server 440 transmits the message transmitted from the first game server 410 to the second game server 420 and the third server 430 that have joined the subscriber group 520.

  The second game server 420 and the third game server 430, which are mirroring game servers, receive the game room related message transmitted from the first game server 410, which is the publisher game server, from the message routing server 440, analyze the message and analyze the game. Perform room mirroring.

  For example, when the message transmitted from the first game server 410 is a message including game room generation information, the second game server 420 and the third server 430 analyze the message and receive information included in the game room generation information. A game room having the same condition as is generated. If the message transmitted from the first game server 410 is a message including game progress information, the second game server 420 and the third game server 430 analyze the message and proceed in the game room of the first game server. Reflect the progress of the game in the mirroring game room.

  According to the configuration described above, when the game to be relayed is a Go game, the Go score information for each player and the Go score information for the commentator's commentary are transmitted through the message routing server 440 and the second game server 420 and the second game server information. The users transmitted to the mirroring game room of the third game server 430 and participating in the mirroring game room of the second game server 420 and the third game server 430 are the players and commentators of the game room of the first game server 410. You can receive game record information.

  FIG. 6 is a diagram showing a game progress and relay state between the publisher game server and the mirroring game server.

  Referring to FIG. 6, the game room 610 of the publisher game server is generated by a player or a relay person, and only the user connected to the publisher game server participates in the game room 610 of the publisher game server. Among the users who participate in the game room 610 of the publisher game server, the player advances the game while exchanging game packets through the publisher game server. The game can include a Go game, a strategy simulation game, a board game, and the like, and an application for game play is installed on a player client connected to the publisher game server.

  The publisher game server transmits information related to the game progress status of the game room such as game room generation information, game command information exchanged during the game progress, and game room end information to the subscriber group of the message routing server 440. As programmed.

  When the game room 610 is generated by the publisher game server, the game room generation information is transmitted to the mirroring game server through the message routing server 440, and the mirroring game server has the same game room 610 generated by the publisher game server. A condition game room 620 is generated.

  In order to generate a game room 620 such as a publisher game server, the mirroring game server generates a virtual dummy player that is recognized as a game room generation subject. The dummy player is a player that is virtually generated because a player having control authority over the game room 620 is required when the game room 620 is generated, and has the same structure as a general player. However, since there is no connection with the client, it is preferable that data transmission / reception to the dummy player is impossible.

  Users connected to the mirroring game server participate in the game room 620 generated in the mirroring game server. When the game room creation message is transmitted from the publisher game server to each mirroring game server that has joined the subscriber group through the message routing server 440, the mirroring game server has the same conditions as the game room information included in the game room creation message. The mirroring game room 620 is generated. The mirroring game server provides the user with the mirrored game room 620 included in the game room list together with the general game room, and the users connected to the mirroring game server receive the mirrored game room. 620 can participate.

  When the game is progressed in the game room 610 of the publisher game server, the game room 610 of the publisher game server transmits information related to the game progress to the message routing server 440, and the message routing server 440 sends the game progress information to the sub-game progress information. The information is transmitted to the mirroring game server that has joined the scriber group, and the mirroring game server transmits the game progress information to the related game room 620. Therefore, users who participate in the mirroring game room 620 can watch the game situation that is progressed on the publisher game server.

  For example, when the Go game is progressed in the game room 610 of the publisher game server, the game record information generated by the players in the game room 610 of the publisher game server is transmitted to the mirroring game server through the message routing server 440 in real time. The game room 620 of the mirroring game server provides the transmitted game record information to the participating spectators and enables the game of Go to be watched.

  FIG. 7 is a diagram illustrating a configuration of a broadcast server system according to a preferred embodiment of the present invention.

  Referring to FIG. 7, a broadcast server system according to an embodiment of the present invention may include a connection control server 710 and a plurality of broadcast servers 720, 730, and 740.

  The connection control server 710 receives the broadcast ID request information from the relay client 701 and provides the broadcast ID and address information of the broadcast servers 720 and 730 to which the relay client 701 transmits moving image streaming data. .

  Conventionally, when the relay client requests a broadcast ID, the connection control server provides the address of one broadcast server to which the relay client transmits the moving picture streaming data. Usually, the connection control server provides address information of a broadcasting server having the least load among a plurality of broadcasting servers.

  However, according to a preferred embodiment of the present invention, the connection control server 710 provides the relay client 701 with the addresses of at least two broadcast servers 720 and 730 that transmit moving image streaming data. Video streaming data is transmitted to the two broadcast servers 720 and 730, respectively. As shown in FIG. 7, when the connection control server 710 provides address information to connect to the broadcast server 1 (720) and the broadcast server 2 (730), the relay client 701 receives the broadcast server 1 (720) and the broadcast server 1 (720). The moving image streaming data is transmitted to the broadcast server 2 (730).

  Here, the address information is the IP address and port number of the broadcast server, but it is obvious to those skilled in the art that other address information can be used.

  Normally, about 2500 people can be connected to the broadcast server at the same time, and when the maximum number of connected people is exceeded, a streaming data interruption phenomenon occurs. Therefore, according to a preferred embodiment of the present invention, the relay client 701 transmits moving image streaming data to a plurality of broadcast servers in order to prevent such streaming data interruption.

  The connection control server 710 manages the IP address and port number of the broadcast server corresponding to the broadcast ID. When the spectator client 702 requests address information corresponding to the broadcast ID, the connection control server 710 corresponds to the spectator client 702 corresponding to the broadcast ID. Provide the IP address and port number of the broadcast server. The relay video streaming data is transmitted to the two broadcast servers 720 and 730, but only the IP address and the port number of one of the two broadcast servers 720 and 730 are provided to the spectator client. To do. The connection control server 710 can provide the address information of the broadcast server 730 with a low load among the two broadcast servers 720 and 730.

  In FIG. 7, when it is determined that the load of the broadcast server 2 (730) is less than the load of the broadcast server 1 (720), the connection control server 710 sends the address information of the broadcast server 2 (730) to the spectator client 702. The spectator client 702 receives the streaming video data of the relay person from the broadcast server 2 (730).

  8 and 9 are flowcharts illustrating a process in which a game room and a mirroring game room that are mirrored by the publisher game server and the mirroring game server are generated, respectively. FIG. 8 is a flowchart illustrating a case where the game player requests the publisher game server to create a mirrored game room, and FIG. 9 is a flowchart illustrating a case where the game relay requests the game room to be generated. .

  Referring to FIG. 8, the game player requests the publisher game server to create a game room through the client (step 810). The player can specify and request a game room to be mirrored on another server in advance. The publisher game server provides an interface for selecting whether to mirror to another server when the game room is created, and the game player can request creation of a game room to be mirrored to another server through the interface.

  The publisher game server generates a game room in response to the player client's game room generation request (step 820). After completing the game room generation, the publisher game server transmits game room generation information to the player client (step 830), and the player client participates in the game room generated by the publisher game server (step 840).

  The publisher game server is joined to the publisher group of the message routing server, and when a mirrored game room is created on another server, it is configured to transmit game room creation information to the subscriber group of the message routing server. ing.

  The publisher game server transmits a game room generation message to the message routing server (step 850). The game room generation message can include a game room title, a game room game ID, game room setting information, and the like, and the destination address of the game room generation message is set in the subscriber group of the message routing server.

  The message routing server that has received the game room generation message transmits the game room generation message to the mirroring game server connected to the message routing server through the socket by joining the subscriber group (operation 860).

  When the mirroring game server that has joined the subscriber group of the message routing server receives the game room creation message, it creates a virtual dummy player for creating the mirroring game room (step 870). As described above, the dummy player has the same structure as that of a general player, but does not have a connection with the client, so data transmission / reception to the dummy player is impossible.

  When the dummy player is generated, the mirroring game server generates a game room having the same conditions as the information included in the received game room generation information and in which the dummy player is set as the game room creator ( Stage 880). When a mirroring game room is generated on the mirroring game server, the number of the mirroring game room is given independently by each mirroring game server, a number prepared in advance for the mirroring game room is given, Numbers are given sequentially as in a general game room. The mirroring game server has a matching table or a matching code for matching the game room number of the publisher game server and the mirroring game room number so that the game room generated by the publisher game server and the mirroring game room can be matched with each other. to manage.

  FIG. 9 is a flowchart illustrating a process of creating a mirroring game room when a game relay requesting the publisher game server to create a game room to be mirrored.

  Referring to FIG. 9, the relay client requests the publisher game server to create a game room (step 911). The relay person can specify and request a game room to be mirrored to another server in advance. The publisher game server provides an interface for selecting whether to mirror to another server when the game room is created, and the relayer can request creation of a game room to be mirrored to another server through the interface.

  The publisher game server generates a game room in response to the game room generation request of the relay client (step 912). After completing the generation of the game room, the publisher game server transmits the game room generation information to the relay client (step 913), and the relay client participates in the game room generated by the publisher game server (step 914). ). After the game room is generated, the game player and the spectator can participate in the generated game room.

  After the relayer joins the game room, the relay client requests a broadcast ID from the broadcast server system (step 921). In response to the broadcast ID request of the relay client, the broadcast server system provides the broadcast server and address information of the broadcast server to which the relay client transmits the video streaming data according to the broadcast ID (step 922). The relay client transmits the moving image streaming data to the corresponding broadcast server (step 923).

  In addition, when the publisher game server is joined to the publisher group of the message routing server and the mirroring game room is created on another server, the game room creation information is transmitted to the subscriber group of the message routing server. Is set.

  The publisher game server transmits a message including game room generation information to the message routing server (step 915). The game room generation information can include a game room number, a game room title, a game ID of the game room, game room setting information, a broadcast ID (assigned to the relay client from the broadcast server system), and the like. The destination address is set in the subscriber group of the message routing server.

  The message routing server that has received the game room creation message transmits the game room creation message to the mirroring game server connected to the message routing server through the socket by joining the subscriber group (step 916).

  The mirroring game servers that have joined the subscriber group of the message routing server each receive the game room generation message, and generate a virtual dummy player for generating the mirroring game room (step 917). As described above, the dummy player has the same structure as a general player, but does not have a connection with the client, and therefore cannot transmit / receive data to / from the dummy player.

  When the dummy player is generated, the mirroring game server generates a game room having the same conditions as the information included in the received game room generation information, and the dummy player is set as a game room creator ( Step 918). The number of the mirroring game room generated in the mirroring game server is independently given by each mirroring game server, a number prepared in advance for the mirroring game room, or a general game room number. The numbers are sequentially given as follows. The mirroring game server manages a matching table or matching code that matches the game room number of the publisher game server with the mirroring game room number so that the game room generated by the publisher game server and the mirroring game room can be matched with each other. To do.

  FIG. 10 is a flowchart showing a process in which audio and video data corresponding to the explanation of the relay person is transmitted to the spectator client of the publisher game server or the mirroring game server.

  Referring to FIG. 10, when a relay client joins a relay game room mirrored by another server, the relay client requests a broadcast ID from the connection control server of the broadcast server system (step 1010).

  The connection control server transmits the broadcast ID and address information of the broadcast server to which the relay client requesting the broadcast ID among the plurality of broadcast servers transmits the moving image streaming data for the explanation to the relay client (step 1020). As described above, the connection control server provides at least two broadcast server address information.

  When the relay client receives two broadcast server address information from the connection control server, it transmits the moving video streaming data of the relay to the broadcast server 1 and the broadcast server 2 (steps 1030 and 1040). Although FIG. 10 shows that the moving picture streaming data is sequentially transmitted to the broadcast server 1 and the broadcast server 2, the relay client can simultaneously send the moving picture streaming data to the broadcast server 1 and the broadcast server 2. Is transmitted.

  Meanwhile, a spectator in the game room of the publisher game server or a spectator participating in the mirroring game room generated in the mirroring game server receives the broadcaster's broadcast ID information when joining the game room (step 1050).

  The spectator client that has received the broadcast ID information requests the address information of the broadcast server corresponding to the broadcast ID from the connection control server (step 1060).

  The connection control server transmits one broadcast server address information of two broadcast server addresses corresponding to the broadcast ID to the spectator client (step 1070). As described above, it is preferable to transmit the address information of a broadcast server with less load among the two broadcast servers.

  When the connection control server provides the address information of the broadcast server 2, the spectator client requests the broadcast server 2 to transmit moving image streaming data (step 1080), and the broadcast server 2 is transmitted from the relay operator. Is received and transmitted to the spectator client (step 1090).

  Through the process of FIG. 10, spectators who have participated in the game room of the publisher game server or the mirroring game room of the mirroring game server can receive the explanation video of the relay person.

  11 and 12 are flowcharts illustrating a process of deleting a mirroring game room in the mirroring game server when the game room is deleted in the publisher game server. FIG. 11 shows a case where a game relay person is not involved, and FIG. 12 shows a case where a game relay person is involved in a mirrored game room.

  Referring to FIG. 11, a player client participating in the game room created on the publisher game server requests exit from the game room (step 1110), and all players participating in the game room created on the publisher game server play games. When leaving the room, the publisher game server deletes the corresponding game room (step 1120).

  When a specific player leaves a game room that is mirrored on the mirroring game server, the publisher game server sends a message to the message routing server that the player has left the game room, and deletes that game room. Transmits a delete message (step 1130).

  A message containing information about a particular player's game room exit and / or game room deletion information is transmitted to a subscriber group of the message routing server, and the message routing server joins the subscriber group through the message routing server and the socket. Each corresponding message is transmitted to the connected mirroring game server (step 1140).

  The mirroring game server determines the number of the mirroring game room corresponding to the game room number included in the corresponding message. The mirroring game room number corresponding to the game room number of the publisher game server can be determined using the matching table or the matching code. The mirroring game server searches for a mirroring game room corresponding to the mirroring game room number determined in this way. If the received message includes the game room exit information of the player who is the publisher of the publisher game server, the mirroring game server deletes the dummy player corresponding to the mirroring game room number (step 1150).

  When all users including the dummy player leave the mirroring game room generated in the mirroring game server, the mirroring game server deletes the mirroring game room (step 1160).

  FIG. 12 is a flowchart illustrating a process in which a mirroring game room is deleted by the mirroring game server when the game room is deleted by the publisher game server when a game relay person is involved.

  Referring to FIG. 12, a relay client participating in the game room created on the publisher game server requests exit from the game room (step 1210), and the game player participating in the game room created on the publisher game server is displayed. If all the users including the user leave the game room, the publisher game server deletes the game room (step 1220).

  When the game room is deleted, the process of transmitting the moving image streaming data corresponding to the commentary of the relay person to the broadcast server is interrupted (step 1230).

  In addition, when a specific user who participates in a game room leaves the game room, the publisher game server transmits the room exit information of the corresponding user to the message routing server and deletes the corresponding game room. A delete message is transmitted (step 1240). The room exit information of a specific user can include deleted game room number information.

  The publisher game server transmits a message including room exit information and / or game room deletion information of a specific user to a subscriber group of the message routing server, and the message routing server joins the subscriber group and receives the message routing server. Each message is transmitted to the mirroring game server connected through the socket (step 1250).

  The mirroring game server determines the game room number in the mirroring game server corresponding to the game room number included in the message. The mirroring game room number corresponding to the game room number of the publisher game server can be determined using the matching table or the matching code. If the user who has left the game room of the publisher game server is a relay person who is the main creator of the game room, the mirroring game server deletes the dummy player corresponding to the mirroring game room number (step 1260). When all users including the dummy player leave the game room in the mirroring game room of the mirroring game server, the mirroring game server deletes the corresponding mirroring game room (step 1270).

  FIG. 13 shows that a game command exchanged in the game room of the publisher game server is transmitted to the mirroring game server so that the game progress in the game room of the publisher game server is reproduced in the mirroring game room of the mirroring game server. It is a flowchart with respect to the process.

  Referring to FIG. 13, a player client participating in the game room of the publisher game server transmits a game command message to the publisher game server (step 1310). The game command may include all game commands in various games. For example, the game command is game record information of a specific player in Go or a movement command for a specific unit in the strategy simulation game.

  When the game progressed in the game room of the publisher game server is a turn-type game such as a go game and a board game, the game command may include command procedure information. If the game proceeding in the game room of the publisher game server is a real-time strategy simulation game, the game command may include time information.

  The game command message includes game room number information of the publisher game server that has received the game command message from the player client.

  Upon receiving the game command message from the player client, the publisher game server transmits the received game command message to the message routing server (step 1320).

  The message routing server transmits a game command message to each mirroring game server that has joined the subscriber group of the message routing server and maintains a connection with the message routing server through a socket (step 1330).

  The mirroring game server receiving the game command message from the message routing server analyzes the game command message and determines the number of the mirroring game room associated with the received game command (step 1340).

  The mirroring game server transmits the game command message received from the message routing server to the mirroring game room corresponding to the determined mirroring game room number (operation 1350). The mirroring game server transmits a game command to a user client including a spectator who has participated in the mirroring game room, and a game application installed in the user client that has received the game command is a game corresponding to the received command. Do the process. According to the procedure of FIG. 13, users who participate in the mirroring game room of the mirroring game server can watch the same game progress as the game progressed in the game room of the publisher game server.

  Although not shown in FIG. 13, a chat message transmitted and received between each player in the game room of the publisher game server can also be provided to the mirroring game room of the mirroring game server by the method shown in FIG. It is self explanatory.

  FIG. 14 is a flowchart illustrating a process of recovering from a failure when a failure occurs in a specific mirroring server.

  Referring to FIG. 14, when a failure occurs in a particular mirroring server among the mirroring servers that participate in the subscriber group of the message routing server, the corresponding mirroring server is generated in the publisher server, and each mirroring server passes through the message routing server. A message routing server is requested for a list of channels or rooms providing information to the server (step 1410).

  The room list request message uses the publisher group as the destination address, and the message routing server transmits the room list request message to the publisher server that has joined the publisher group (step 1420).

  The publisher server that has received the room list request message from the message routing server searches for information for each room currently providing information to the mirroring server (step 1430).

  In addition, the publisher server generates history data indicating generation and state change of each searched room (step 1440). If the searched room is a game room, game history data is generated for a game that is progressing in the game room. Here, the game history data means that the mirroring server can accurately provide the current game progress status to the spectator, and means the data in which the game progress history progressed before the occurrence of the failure is recorded. For example, the game history data is Go game data in the case of a Go game, and game command data exchanged between players in the case of a strategy simulation game. Of course, depending on the type of game, generation of such game history data may be impossible, or generation of game history data may not be required.

  The publisher server transmits a message including room list information and history data of each room to the message routing server (step 1450).

  The message routing server transmits the message from the publisher server to all mirroring servers participating in the subscriber group (step 1460). Even if only one mirroring server of each mirroring server participating in the subscriber group fails, the message is transmitted to all mirroring servers participating in the subscriber group according to the transmission principle of the message routing server. .

  The mirroring server that has not requested the room list among the mirroring servers that have received the message including the room list and the history data of each room from the message routing server ignores the received message. The mirroring server that requested the room list generates a mirroring room again based on the received room list and the history data of each room (operation 1470).
