The present invention relates to a game relay system and method using server mirroring, and more particularly, to a system and method that allows a plurality of users to watch the game relay without being limited by the server capacity.

In recent years, with the development of game technology, watching games have become a culture as well as sports. In particular, the number of users who enjoy watching games in a strategy simulation game such as Go or StarCraft continues to increase, and new systems for game relaying are being developed.

In the early days, the method of broadcasting a camera by shooting a game situation was mainly used, but there was a limitation that the game could be relayed only to TV viewers, and many users demanded a system for watching games through a computer.

The most problematic problem in the game relay system that can watch a game through a conventional computer was the server's load. When a large number of users access the game server for game watching, there is a problem that the game watching service cannot be provided to a certain number of users due to the capacity limitation of the server.

1 is a diagram showing an example of a conventional game relay system.

In the case of an online game service to which a large number of users connect, the user selects one server among the plurality of servers 100, 102, and 104, and the user plays or watches the game on the selected server.

For example, when a user accesses the first game server 100, the user may communicate only with users accessing the first game server 100, and the game may be played only in a game room created on the first game server. You can play or watch.

That is, a user who accesses the first game server 100 may not participate in the game room created in the second game server, nor can the user observe the game situation that is performed in the game room created in the second server.

In recent years, the game of Go or strategy simulation game is increasing in addition to the game play, the number of users who enjoy the game mainly on the watching game, and in the case of the famous pro knights game, a large number of users participate in the game.

However, when the system as shown in FIG. 1 is used, when the game is played between professional articles in the first game server, and the specific relay is explaining the situation of the game, the second game server 102 and the third game server 104 are used. There was a problem that users connected to the first game server can not observe the situation of the game and the commentary of the relay at all.

The first game server 100 may transmit the progress of the match to the first game server 100 to the second game server and the third game server, but in this case, the traffic may increase rapidly and control for delivery of the match progress may be performed. The server had to be provided, and the control server had to be composed of quite complicated logic.

In order to solve the problems of the prior art as described above, the present invention proposes a game relay system that allows a plurality of users to watch the game relay without being limited by the server capacity.

Another object of the present invention is to propose a game relay system that enables users who are connected to a server where a game is played and another server using server mirroring to receive commentary of the game progress and the relay.

A game relay method using server mirroring is provided.

Hereinafter, exemplary embodiments of a game relay system and method using server mirroring according to the present invention will be described in detail with reference to the accompanying drawings.

2 is a diagram illustrating a configuration of a game relay system using server mirroring according to an exemplary embodiment of the present invention.

2, a game relay system using server mirroring according to an embodiment of the present invention may include a plurality of game servers 200, 202, and 204, a message routing server 206, and a broadcast server system 208. Can be. A plurality of user clients 220, 222, 224, 226, 228 and 230 are connected to a game relay system using server mirroring according to an embodiment of the present invention.

The present invention relates to a method and system for relaying a game played in a specific game room of a game server (200, 202, 204). Here, the game played in a specific game room of the game server may include various kinds of online games that allow users to play the game through competition or cooperation. For example, the game relayed by the present invention may be a game such as Go, Shogi, or may be a real-time strategy simulation game such as StarCraft or Warcraft. In addition to these games, various kinds of board games and competitive games may be used in the game relay system according to the present invention.

In general, when a game is in progress in a specific game room of the first game server 200 and the relay is participating in and relaying the game room, the clients 220, 222, 224, 226, 228, and 230 Participate in the game room of the first game server 200 to watch the game and receive commentary of the relay.

However, as described above, when the game relay spectator increases so that the first game server 200 can no longer accommodate the user, the users who do not access the first game server 200 watch the game relay. There was a problem that you can not watch.

The present invention proposes a method in which users who do not have access to a game server in which a game room where a game is relayed, can watch a game relay by using server mirroring. For example, according to the present invention, when a game relay is performed in a specific game room of the first game server 200, the users connected to the second game server 202 and the third game server 204 may also be registered. 1 It is possible to watch the game relaying in the game room of the game server 200.

According to a preferred embodiment of the present invention, a game room of one server is mirrored to another server so that users connected to the other server can also watch the game relay through the mirrored game room.

In general, a game room in which a relay is performed includes a player who directly plays the game, a repeater who explains the player's game, and an observer who watches the game and is provided with commentary. Users participating in the game room mirrored to the other server may be provided with commentary information of the game progress and the relay by the players, such as users participating in the game room where the relay is performed.

In FIG. 2, the game room created in the first game server 200 is mirrored to the second game server 202 and the third game server 204, and the game room is different from the game room like the first game server 200. A server mirrored to the server is called a publisher game server, and mirrors a server that mirrors game rooms of other game servers, such as the second game server 202 and the third game server 204. Let's say.

When a game relay is performed in the game room to the first game server 200, the first game server 200 becomes a publisher game server, and the first game server 200 is connected to another server from a game player or a game relay. Receive game room creation request information to be mirrored. The game player or game repeater requesting the creation of a game room inputs information indicating a room mirrored to another server for game relaying when the game room creation request is made.

The first game server generates a game room to be mirrored to another server in response to a game room creation request of the game player or game relay. In the generated game room, game players, relays, spectators and the like other than the game room creator participate.

Information about the game room generated in the first game server 200 is transmitted to the message routing server 206. Here, the information about the game room may include a game room type, user information participating in the game room, a game room title, and a game room number. In addition, the first game server 202 transmits a game progress information message in the generated game room to the routing server 200. Here, the game progress information may include game command information transmitted by game players for the online game progress. For example, when the game played in the first game server 200 is a Go game, the game command information may be Go notation information. When the game played in the first game server 200 is a strategy simulation game, the game command information may include an attack command of a unit, a move command of a unit, and the like.

In addition, the game progress information may include a chat message exchanged between the player, the relay and the spectator participating in the game room of the first game server 200.

According to a preferred embodiment of the present invention, message routing server 206 is used to simplify communication between servers for game room mirroring. The message routing server 206 provides the game room creation information message and the game progress information message provided by the first game server 200 to the second game server 202 and the third game server 204.

According to a preferred embodiment of the present invention, the message routing server 206 supports the function of managing a plurality of connections into one group.

3 is a diagram illustrating a group created in a message routing server according to an exemplary embodiment of the present invention.

Referring to FIG. 3, a subscriber group 300 and a publisher group 302 are created in the message routing server according to an embodiment of the present invention, and the subscriber group is a game of the publisher game server. A mirroring game server that mirrors a room joins a group, and a publisher group is a group that a publisher game server that provides game room information to be mirrored joins.

In FIG. 2, the first game server 200, which is a publisher game server, joins the publisher group 302, and the second game server 202 and the third game server 204, which are mirroring game servers, are subscribers. Join group 300.

The first to third game servers 200, 202, and 204 connected to the message routing server 206 are either the publisher group 302 or the subscriber group 300 of the message routing server 206 at server startup. It is configured to join one, and the message routing server 206 joins the subscriber group 300 or the publisher group 302 at the request of the connected servers.

According to a preferred embodiment of the present invention, the first game server 200, which is a publisher game server, provides a message routing server 206 with a message relating to game room information to be mirrored in a multicast manner. The first game server 200, which is a publisher game server, provides the game routing related information to the message routing server by including only the information of the message transmitted to the subscriber group to the message routing server 206. That is, the game room-related message that the first game server 200 transmits to the message routing server 206 may include address information of the second game server 202 and the third game server 204 to mirror the game room information. It contains no subscriber group identification information to which the message will be sent.

When the message routing server 206 receives a message to be transmitted to the subscriber group from the first game server 200 which is the publisher game server, the message routing server 206 transmits the message from the publisher game server to all the mirroring game servers participating in the subscriber group. The sent message. That is, the message routing server 206 transmits the message transmitted from the first game server 200 to the second game server 202 and the third server 204 participating in the subscriber group.

The message routing server 206 determines only whether the message being sent is a message to be sent to servers in a subscriber group or a message to be sent to servers in a publisher group, and thus receives the received message as a server or sub server in a publisher group. It only plays the role of transmitting to the server of the scriber group, and does not perform the analysis, determination and control procedure of the received message.

Accordingly, the message routing server 206 can have a simpler configuration than the control servers for exchanging information between the existing servers, and the message transmitted from the publisher game server is further simplified without having to specify the receiver of the message. The message traffic can also be reduced, as it can be transmitted in a conventional manner.

The second game server 202 and the third game server 204, which are mirroring game servers, receive a game room related message transmitted by the first game server 200, which is a publisher game server, from the message routing server 206. Analyzes the message and performs game room mirroring.

For example, when the message transmitted from the first game server 200 is a message including game room creation information, the second game server 202 and the third server 204 analyze the message to generate game room creation information. Create a game room with the same conditions as the information contained in. When the message transmitted from the first game server 200 is a message including state change information of the game room, the second game server 202 and the third game server 204 analyze the message to determine the first game server. The state of the mirroring game room of the second game server 202 and the third server 204 is changed to the same state as the game room.

With the above-described configuration, when the game to be relayed is a Go game, the Go notation information by the players and the Go notation information for the commentator's comment are transmitted through the message routing server 206 and the second game server 202 and the game. The users who participated in the mirroring game room of the third game server 204 and participated in the mirroring game room of the second game server 202 and the third game server 204 are players in the game room of the first game server 200. And notation information can be provided by the commentator.

On the other hand, the voice and video information of the relay through the broadcast server system 208, the user participating in the game room of the first game server 200, which is a publisher game server, the second game server 202 and the third game server that is a mirroring game server It is provided to users who participate in the mirroring game room of the game server 204.

When the repeater participates in the game room of the first game server 200, which is the publisher game server, the repeater requests a broadcast ID for broadcast video of the broadcast server system 208, and the broadcast server system broadcasts for game commentary. It provides ID and address information of broadcast server to broadcast voice and video information of repeater.

The game application of the repeater is provided with a module for coding the repeater's voice and video into the video streaming data, the video streaming data including the voice and video of the repeater is transmitted to the broadcast server determined by the broadcast server system.

Users who participated in the game room created in the first game server 200, which is a publisher game server, and the mirrored game room created in the second game server 202 and the third game server 204, which are mirroring game servers, participated in each game. From the room, broadcast ID information through which commentator information is streamed is provided.

That is, according to a preferred embodiment of the present invention, game progress information such as Baduk notation is transmitted to the game room mirrored to the mirroring game server through the message routing server 206, the commentary video streaming data of the relay is broadcast server system It is transmitted to each user client participating in the game room of the publishing game server and the mirroring game room of the mirroring game server.

Therefore, even if the spectator of the first game server 200 exceeds the acceptance limit of the server, the users can access the second game server 202 and the third game server 204 to watch the game.

4 is a view showing the state of the game of the publishing game server and the mirroring game server according to an embodiment of the present invention.

Referring to FIG. 4, the game room 400 of the publisher game server is created by a player or a repeater, and only users who access the publisher game server participate. Among the users participating in the game room 400 of the publisher game server, the players proceed with the game while exchanging game packets through the publisher game server. The game may include a Go game, a strategy simulation game, a board game, and the like, and an application for game play is installed in a client of a player connected to the publisher game server.

The game room of the publisher game server is programmed to send information related to the game progress of the game room, such as game room creation, game command information exchanged during game play, and game room termination, to the subscriber group of the message routing server.

When a game room is created on the publisher game server, the game room creation information is transmitted to the mirroring game server through the message routing server, and the mirroring game server creates a game room with the same conditions as the game room created on the publisher game server. do.

In order to create a game room such as a publisher game server, the mirroring game server creates a virtual dummy player recognized as the creator of the game room. The dummy player is a virtually created player because it needs a player who has control over the game room when the game room is created. Since the dummy player has the same structure as a normal player but does not have a connection with a client, the dummy player may transfer data to the dummy player. It is desirable to make it impossible to transmit and receive.

Users connected to the mirroring game server participate in the game room 402 created in the mirroring game server. When a game room creation message is sent from the publisher game server to each mirroring game server participating in the subscriber group through the message routing server 206, the mirroring game server is subject to the same conditions as the game room information included in the game room creation message. Create a mirroring game room. In addition to the general game room, the mirroring game server also provides a mirrored game room as a game room list, and users connected to the mirroring game server can join the mirrored game room.

When a game is played in the game room 402 of the publisher game server, the game room 402 of the publisher game server transmits information related to the game progress to the message routing server 206, and the message routing server 206 It transmits to the mirroring game servers participating in the subscriber group, and the mirroring game server transmits the information related to the game progress to the related game room 402. Therefore, the users who participate in the mirroring game room can watch the game situation progressing on the publisher game server.

For example, when the Go game is played in the game room 400 of the publisher game server, the notation information generated by the players of the game room 400 of the publisher game server may be mirrored through the message routing server in real time. It is transmitted to the game room 402 of the server, the game room 402 of the mirroring game server provides the notation information transmitted to the participating spectators to enable watching games.

5 is a diagram illustrating a configuration of a broadcast server system according to an exemplary embodiment of the present invention.

Referring to FIG. 5, a broadcast server system according to an embodiment of the present invention may include a connection control server 500 and a plurality of broadcast servers 502, 504, and 506.

The access control server 500 receives the broadcast ID request information from the relay client 510 and provides the broadcast client with the broadcast ID and address information of the broadcast server to which the relay client transmits the video streaming data.

In the related art, when the relay client requests a broadcast ID, the access control server 500 provides one broadcast server address to which the relay client 510 transmits video streaming data. In general, the access control server 500 provided address information of a broadcast server having the least load among the plurality of broadcast servers.

However, according to a preferred embodiment of the present invention, the access control server 500 provides at least two broadcast server addresses for the relay client to transmit the video streaming data, and the relay client 510 connects the two broadcast servers. Send video streaming data. As illustrated in FIG. 5, when the access control server 500 provides address information to access the broadcast server 1 502 and the broadcast server 2 504, the relay client 510 may transmit the broadcast server 1 502. And transmitting the streaming video data to each of the broadcast server 2 (502).

Here, the address information may be an IP address and a port number of the broadcast server, and it will be apparent to those skilled in the art that other address information may be used.

Typically, about 2500 people can access the broadcast server simultaneously. If the maximum number of users is exceeded, streaming data may be interrupted. Therefore, according to a preferred embodiment of the present invention, in order to prevent such streaming data truncation, the relay client transmits the video streaming data to the plurality of broadcast servers.

The access control server 500 manages the IP address and port number of the broadcast server corresponding to the broadcast ID, and when the spectator client requests address information corresponding to the broadcast ID, the IP of the broadcast server corresponding to the broadcast ID is requested. Provide the address and port number. The video streaming data of the relay is transmitted to the two broadcast servers, and the spectator client is provided with only the IP address and port number of one of the two broadcast servers. The access control server 500 may provide address information of a broadcast server having a low load among the two broadcast servers.

In FIG. 5, when it is determined that the load of the broadcast server 2 504 is less than the load of the broadcast server 1 502, the connection control server 500 transmits the address information of the broadcast server 2 504 to the spectator client 512. And the spectator client 512 receives the video streaming data of the relay from the broadcast server 2.

6 is a flowchart illustrating a process of creating a game room in a mirroring game server when creating a game room in a publishing game server according to an exemplary embodiment of the present invention.

Referring to FIG. 6, the relay client requests the publisher game server to create a game room (step 600). The relay may request in advance that it is a game room to be mirrored to another server. The publisher game server provides an interface for selecting whether to mirror to another server when creating a game room, and the relay may request creation of a game room to be mirrored to another server through the interface. The creation of the game room may be created by a user other than the relay (eg game player).

The publisher game server creates a game room in response to the game room creation request of the relay client (step 602). The publisher game server sends the game room creation information to the relay client after completing the game room creation (step 604), and the relay client joins the game room created in the publisher game server (step 606). After the game room is created, the game may be joined to a game room in which players and spectators are created.

After the relay joins the game room, the relay client requests a broadcast ID from the broadcast server system (step 608). In response to the broadcast ID request of the relay client, the broadcast server system provides address information of the broadcast server to which the relay client transmits video streaming data corresponding to the broadcast ID and the broadcast ID (step 610). The relay client transmits the video streaming data to the broadcast server (step 612).

In addition, the publisher game server has joined the publisher group of the message routing server and is set to transmit game room creation information to the subscriber group of the message routing server when a game room to be mirrored is created on another server. .

FIG. 11 is a conceptual diagram illustrating a message transmitted from a publisher game server to mirroring game servers belonging to a subscriber group through a message routing server according to an embodiment of the present invention.

Referring to FIG. 11, the publisher game server 1104 and the mirroring game servers 1100 and 1102 participating in the publisher group and the subscriber group of the message routing server maintain a connection with the message routing server through a socket. do.

As shown in FIG. 11, when the publisher game server 1104 wants to deliver a message to the mirroring game servers participating in the subscriber group, the publisher game server multicasts the subscriber group with the destination address. To send the message.

The message routing server 206 forwards the message sent from the publishing game server to each of the mirroring game servers through sockets maintaining connections with the mirroring game servers 1100 and 1102 belonging to the subscriber group.

Referring back to FIG. 6, the publisher game server sends a game room creation message to the message routing server (step 612). The game room creation message may include the game room number, the game room title, the game ID of the game room, the game room setting information, and the broadcast ID (the relay client is assigned by the broadcast server system). The destination address is set to the subscriber group of the message routing server.

Upon receipt of the game room creation message, the message routing server joins the subscriber group with the game room creation message and transmits the game room creation message to each mirroring game server maintaining a connection with the message routing server through the socket (step 614).

Each mirroring game server participating in the subscriber group of the message routing server receives the game room creation message and generates a virtual dummy player for the game room creation (step 616). As described above, since the dummy player has the same structure as the general player but does not have a connection with the client, it is impossible to send and receive data to and from the dummy player.

When the dummy player is created, the mirroring game server creates a game room having the same conditions as the information included in the received game room creation information and in which the dummy player is set as a game room creator (step 618). When creating a game room on the mirroring game server, the number of mirrored game rooms can be independently assigned by each mirroring game server, and a number prepared in advance for the mirroring game room can be assigned. May be However, each of the mirroring game servers has a matching table that matches the game room numbers of the publisher game servers and the mirrored game room numbers so that the game rooms created in the publisher game server and the mirrored game rooms are matched with each other.

7 is a flowchart illustrating a process of transmitting audio and video data for commentator's commentary to a spectator client of a publishing game server or a mirroring game server according to an exemplary embodiment of the present invention.

Referring to FIG. 7, when the relay client participates in a relay game room mirrored to another server, the relay client requests a broadcast ID from the access control server of the broadcast server system (step 700).

The access control server transmits the broadcast ID and the address information of the broadcast server to which the relay client which requested the broadcast ID among the plurality of broadcast servers transmits the video streaming data about the commentary (step 702). As described above, the access control server provides at least two broadcast server address information.

When the relay client receives two broadcast server address information from the access control server, the relay client transmits the video streaming data of the relay to the broadcast server 1 and the broadcast server 2 (steps 704 and 706). Although FIG. 7 illustrates that video streaming data is sequentially transmitted to broadcast server 1 and broadcast server 2, the relay client simultaneously transmits video streaming data to broadcast server 1 and broadcast server 2.

On the other hand, the spectator in the game room of the publisher game server or the spectator who participated in the mirroring game room generated in the mirroring game server receives the broadcaster's broadcast ID information when participating in the game room (step 708).

The spectator client provided with the broadcast ID information requests address information of the broadcast server corresponding to the broadcast ID from the access control server (step 710).

The broadcast server transmits the broadcast server address information of one of two broadcast server addresses corresponding to the broadcast ID to the spectator client (step 712). As described above, it is preferable to transmit address information of a broadcast server having a low load among the two broadcast servers.

If the access control server provides the address information of the broadcast server 2, the spectator client requests the broadcast server 2 to transmit the video streaming data (step 714), and the broadcast server 2 provides the video streaming data for the commentary transmitted from the relay. Send to the spectator client (step 716).

7, the spectators participating in the game room of the publisher game server or the mirroring game room of the mirroring game server may be provided with commentary videos of the relay.

8 is a flowchart illustrating a process of deleting a mirrored game room from a mirroring game server when deleting a game room from a publisher game server according to an exemplary embodiment of the present invention.

Referring to FIG. 8, a client of a relayer participating in a game room created at the publisher game server requests to exit the game room (step 800), and all users participating in the game room created at the publisher game server are game rooms. If it exits, the publisher game server deletes the game room (step 802).

If the game room is deleted, the process of transmitting video streaming data about the commentator's commentary to the broadcast server is stopped (step 804).

In addition, when the user participating in the game room leaves the game room, the publisher game server transmits the room exit information of the user to the message routing server (step 806). Room exit information of a specific player may include number information of the deleted game room.

The publisher game server sends a message to the subscriber group of the message routing server that contains the room exit information for a particular player, and the message routing server joins the subscriber group to maintain a connection through the message routing server and the socket. A message is sent to each mirroring game server in operation 808.

The mirroring game server determines a 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 may be determined using the above-described matching table or matching code. If the user who left the room in the publisher game server is the relay, the mirroring game server deletes the dummy player corresponding to the determined mirroring game room number (step 808). In addition, when all users including the dummy player leave the room in the game room mirrored to the mirroring game server, the mirroring game server deletes the game room (step 810).

9 is a flowchart illustrating a process of transferring game commands exchanged in a game room of a publishing game server to a mirroring game server so that a game progress is reproduced in a mirroring game server according to an exemplary embodiment of the present invention.

Referring to FIG. 9, a player of a player who joins a game room of a publisher game server and plays a game transmits a game command message to the publisher game server (step 900). The game command may include all game commands in various games. For example, the game command may be notation information of a specific player in Go, or may be a move command for a specific unit in a strategy simulation game.

When the game played in the game room of the publisher game server is a turn-based game such as a game of go, board, the game command may include the order information of the command. If the game played 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 may include game room number information of the publisher game server that receives the game command message.

The publisher game server receiving the game command message from the player client transmits the received game command message to the message routing server (step 902).

The message routing server sends a game command message to the subscriber group joining the subscriber group and sending a game command message to each of the mirroring game servers maintaining the connection through the socket (step 904).

Each mirroring game server that receives the game command message from the message routing server analyzes the game command message to determine the number of the mirroring game room associated with the received game command (step 906).

The mirroring game server transfers the game command message received from the message routing server to the determined mirroring game room (step 908). The mirroring game room of the mirroring game server transmits a game command to clients of participating users, and a game application installed in the user clients that receive the game command performs a game process corresponding to the received command. By the procedure as shown in FIG. 9, users participating in the mirroring game room of the mirroring game server may observe the same game progression as the game played in the game room of the publishing game server.

Although not shown in FIG. 9, it will be apparent to those skilled in the art that chat messages transmitted and received between players in the game room of the publisher game server may also be provided to the mirroring game room of the mirroring game server in the same manner as in FIG. 9. will be.

10 is a flowchart illustrating a process of recovering from a failure when a failure occurs in a specific mirroring game server according to an exemplary embodiment of the present invention.

Referring to FIG. 10, when a failure occurs in a specific mirroring game server among the mirroring game servers participating in the subscriber group in the message routing server, the mirroring game server is created in the publishing game server on the message routing server and the message routing server. In step 1000, a list of game rooms providing game room information to the mirroring game servers is requested.

The game room list request message uses the publisher group as the destination address, and the message routing server delivers the game room list request message to the publisher game server participating in the publisher group (step 1002).

Receiving the game room list request message from the message routing server, the publisher game server retrieves information about game rooms currently providing game room information to the mirroring game servers (step 1004).

In addition, the publisher game server generates history data for each game in progress in the retrieved game room (step 1006). Here, the history data refers to data in which the game progress history, which is performed before the failure, is recorded so that the mirroring game server can reflect the current game progress. For example, in the case of a Go game, the history data may be notation data of Go, and in the case of a strategy simulation game, the game command data may be exchanged between players. Of course, the generation of such historical data may be impossible or generation of historical data may not be required depending on the type of game.

The publisher game server sends to the message routing server a message containing game room list information and game history data in each game room (step 1008).

The message routing server sends a message from the publisher game server to all mirroring game servers participating in the subscriber group (step 1010). Even if a failure occurs in only one mirroring game server among the mirroring game servers participating in the subscriber group, it is transmitted to all mirroring game servers participating in the subscriber group according to the transmission principle of the message routing server.

Among the mirroring game servers that have received the game room list and history data messages from the message routing server, the mirroring game servers that do not request the game room list ignore the received message. The mirroring game server requesting the game room list re-creates the mirroring room based on the received game room list and history data (step 1012).

Although the above has been described with reference to a preferred embodiment of the present invention, those skilled in the art to which the present invention pertains without departing from the spirit and scope of the present invention as set forth in the claims below It will be appreciated that modifications and variations can be made.

As described above, according to a preferred embodiment of the game relay system and method using the server mirroring of the present invention, there is an advantage that a number of users can watch the game relay without being limited by the server capacity.

In addition, according to a preferred embodiment of the present invention, users connected to the server and other servers where the game is played using server mirroring may be provided with commentary of the game progress and the relay, and message routing with relatively simple logic. By performing server mirroring using the server, there is an advantage that can solve the problem of server load during game relay.
