Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

The disconnection reconnection method provided by the application can be applied to the application environment shown in fig. 1. The application environment includes a client 101 and a server 102, which can communicate via a network. The server side comprises a first game business process, a second game business process and a connection management process. When the game application program normally runs, the first game business process is connected with the client through the connection management process (the client is also connected with the second game business process through another connection management process, which is not shown in fig. 1), and in addition, the first game business process and the second game business process can be communicated. When a network disconnection occurs, the connection between the client and the connection management process is cut off, and each game service process cannot perform normal communication with the client (as shown in fig. 2, at this time, the content of "reconnection … …" can be displayed on the client interface), and disconnection reconnection is required at this time.

The client 101 may be, but not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices, various types of game applications may be installed in the client 101, and the server 102 may be a server (to be noted, in the embodiment of the method of the present invention, it is simply referred to as "server") that provides the game applications, or an external platform (i.e., the server and a third end other than the client, in which case the client may run the game applications in the server by means of the external platform). The server may be implemented by an independent server or a server cluster composed of a plurality of servers.

In one embodiment, as shown in fig. 3, a disconnection reconnection method is provided, and is applied to a server, which can be developed by using languages such as C + +, gold (parallel programming language for server implementation).

The method comprises the following steps:

s301, when a disconnection reconnection request sent by a client through a connection management process is received, determining a session corresponding to the client.

The client can install a game application program or can access a web game, and furthermore, the users using the client can register and log in an account in the game application program (which may include a mobile phone game, a web game, an internet game, and the like), and the game application program can be started through the registered or logged-in account. In some embodiments, the client may also specifically refer to a game account registered in the game application.

The server can independently run business process entities in the background, which can be referred to as entities. Further, the number of entities may be more than one, for example, including a first game business process and a second game business process. The first game business process may refer to a business process providing basic functions in the server, such as a business process managing a game hall and a room; the second game business process may refer to an additional function provided in the server, such as a business process of managing a copy, a fighting state.

In some embodiments, the game service process may also be a game service process in an external platform, the game service process in the server may be determined as the first game service process, and the game service process in the external platform may be determined as the second game service process, and vice versa, the game service process in the external platform may be determined as the first game service process, and the game service process in the game server may be determined as the second game service process. In addition, the external platform may be a WeChat platform, a QQ platform, or the like. The game service process in the external platform is consistent with the game service process in the server in the implementation process of disconnection reconnection of the game service process, for example: in the disconnection reconnection process, firstly, the connection C between the client and the game business process in the external platform is recovered, and the connection D between the client and other game business processes is recovered through the connection C.

The connection management process may refer to a process of a connection relationship between a server and a client, and may be Connd, where Connd is one of game process instances in a server, and is used to establish and maintain a connection between the client and a game service process in the server, and perform communication through Gobus (shared memory communication channel between processes) and Entity. In addition, when the external platform exists, the connection management process may refer to an external connection agent process (Relaysvr) for managing message communication between the client and an external connection service in the external platform, the Relaysvr and the Entity in the server communicate through an inter-process communication pipe, and in addition, the game service process in the external platform and the game service process in the server may communicate through a remote process communication agent. Furthermore, a Connd may correspond to a game service process, all messages of the game service process and the client may be forwarded through a connection management process in the connection layer, and the game service process does not directly communicate with the client.

A session refers to a data structure and related operations for a server to manage a connection, and is an actual management structure connected in an upper-level Entity. After the server receives the notification of the connect (the notification may refer to a disconnection reconnection request, where the request includes identification information of the client), a session corresponding to the connection is searched according to the identification information of the client, and if the session exists, this indicates that the connection is a disconnection reconnection (or a top number), and the session can control and manage the connection, so that the server can manage the connection information corresponding to the connection through the session.

Wherein, broken reconnection can refer to complete reconnection and partial reconnection. Specifically, "fully reconnect" means that the client completely loses the context of the game and cannot know the current state of the game application, for example: killing process re-logging, shutting down and restarting and the like; the term "partial reconnection" refers to the disconnection and reconnection after the client still retains partial game context, for example, the network flashes the Wifi network to switch to the 4G network.

S302, recovering the first connection according to the session; the first connection is formed by a first game business process in the server and the client through the connection management process.

The game can be various games needing network connection, and a game player (which can refer to a game account logged in a client) can have the situation that the connection between the client and the server is switched under the situations of game flash quit, phone answering, network switching and the like, at this time, if the game player needs to continue playing, the connection between the client and the server needs to be reestablished, namely disconnection reconnection is realized, after the disconnection reconnection is completed, the client can continue to communicate with the server, and further the game state before disconnection can be recovered (or the current state of a game application program in the client, including the states of other game players and the like, can be recovered).

The connection refers to an end-to-end communication channel established between the client and the server, and specifically may refer to a connection of a game service process in the client and the server. In addition, the connection may also refer to not only an end-to-end connection, for example, a game service process may be connected to a client through a connection management process. The connection may be a Websocket (http protocol-based application layer protocol for keeping a long connection between the game service process and the client), a TCP connection, a reliable UDP connection, or the like. Specifically, the first connection refers to a connection between the first game business process and the client. Before disconnection, historical connection exists between the first game business process and the client, the historical connection is cut off (mainly, the connection between the client and the connection management process is cut off) when the disconnection occurs, and at the moment, the connection between the client and each game business process needs to be restored by restoring the connection between the client and the connection management process.

The server side of the step restores the first connection under the triggering of the disconnection reconnection request, and can restore the communication between the first game service process and the client side. Further, the restoring of the first connection may be implemented by a processor (which may be independent of the first game service process, the second game service process, and the connection management process) in the server, or may be implemented directly by the connection management process. Specifically, there may be at least two implementations: 1. when a processor in the server receives a disconnection reconnection request, triggering a connection management process to recover the connection between the first game service process and the client; 2. and when receiving the disconnection reconnection request, the connection management process directly restores the first connection. Specifically, when the client sends the disconnection reconnection request, the disconnection reconnection request is sent through a new connection L1, when the connection management process receives the disconnection reconnection request, a corresponding session is determined according to client identification information included in the disconnection reconnection request, a connection L2 corresponding to the client is determined from the session, L2 is a connection between the first game service process and the connection management process, a correspondence between L1 and L2 is established, when the first game service process sends information related to the client through L1, the connection management process can send through L2, and at this time, the connection between the first game service process and the client is restored.

S303, if the second connection to be recovered is determined to exist, acquiring a connection address of the second connection; the second connection is the connection between a second game service process in the server and the client, and the connection address is obtained by the first game service process from the second game service process.

After the game application program is started, the first game business process and the second game business process can communicate through a specific communication channel so as to realize frame synchronization. Further, assuming that the first game service process is Roomsvr, which is one of game process instances in the server and is used for processing peripheral transactions, the second game service process is Battlesvr, which is one of game process instances in the server and is used for processing battle transactions, and the client establishes a connection with Battlesvr when the player enters a copy or battle. The Roomsvr and the Battlesvr can communicate through a communication channel, the Roomsvr can know the state of a player in a copy or a battle from the Battlesvr and can know the connection information of the Battlesvr and the client, and the connection information can include connection state (disconnection, and the like), connection address, and the like.

If there is a connection (i.e., a second connection) between the second game service process and the client, the second connection needs to be recovered, and the connection management process is not directly connected to the second game service process, so there may be no connection address of the second connection in the connection management process. Therefore, the connection address of the second connection needs to be acquired, and the first game service process can acquire the connection address of the second connection through a communication channel with the second game service process, so that the connection management process can acquire the connection address of the second connection based on the connection address. Further, the connection address may be a URL (uniform resource locator) or the like.

In some embodiments, the first game business process and the second game business process can each be at least one. For convenience of description, a first game process (the number of second game processes is not limited) is taken as an example for explanation.

In this step, the first game service process acquires the connection address of the second connection from the second game service process, and the second game service process does not need to communicate with the client, that is, the server only needs to pay attention to the connection condition of a certain game service process and the client in the disconnection reconnection process, and does not need to receive the connection request sent by the client and perform connection switching and other operations for many times. Further, in some embodiments, the first connection may be referred to as a master connection and, correspondingly, the second connection may be referred to as a slave connection, the slave connection relying on the master connection for recovery.

S304, triggering the connection management process to return the connection address to the client through the first connection so as to recover the second connection.

This step may be performed by the processor in the server or the first game service process returning the connection address to the client. After receiving the connection address, the client can access the connection address to further realize second connection with the second game service process.

In the disconnection reconnection method for the game provided in the above embodiment, when a disconnection occurs, the client sends a disconnection reconnection request to the connection management process, the first connection between the first game service process and the client is restored through the connection management process, and the connection address between the second game service process and the client is returned to the client through the first connection, so as to restore the second connection between the second game service process and the client. Under the condition that a plurality of connections exist, the reconnection states of the client at a plurality of entitlements are synchronized through interprocess communication, so that the synchronization of player data on different game business processes can be effectively ensured.

In one embodiment, the step of obtaining the connection address of the second connection includes: acquiring the connection address acquired by the first game service process from the second game service process through a communication channel; the communication channel includes at least one of a shared memory and a remote process communication agent.

The first game service process may obtain connection information of the second game service process through the communication channel, where the connection information may include a connection state (which may be connected or disconnected) of the second game service process and each client, a connection address, connection setup time, connection disconnection time, and the like.

When the server is a server corresponding to the game application, the shared memory may be Gobus, and the remote procedure communication agent may be Gobusd [ a communication agent for cross-machine RPC (remote procedure call) ]. Fig. 4 is an application scenario of the disconnection reconnection method, in which the first game service process Roomsvr and Battlesvr communicate with each other through Gobusd, and the game state of the connected client and the connection information with the client can be synchronized in real time between Roomsvr and Battlesvr, so that the states of the players in the game service processes are consistent. The game state may refer to a state formed by all players after performing interactive operations in the game application, and may be a level, a location (e.g., in a game hall, in a room, in a copy, in combat, etc.), equipment status, player information (e.g., camp, hero, blood volume, etc.), a random seed, and the like of each player.

In the above embodiment, the first game service process and the second game service process are connected through the communication channel, and in the disconnection reconnection process, the connection management process connected with the second game service process is not needed to perform connection management, and the connection management process corresponding to the first game service process recovers the first connection, so that the second connection is recovered through the first connection, thereby reducing the communication cost between the client and the game service process and improving the disconnection reconnection efficiency.

In some embodiments, when the combat is completed and the player is offline, the connection state of the player is synchronized among the game business processes of the server.

In one embodiment, after the step of recovering the first connection according to the session, the method further includes: determining historical connection corresponding to the client according to the session; the historical connection is the connection between the first game business process and the client before disconnection; acquiring uplink connection information and downlink connection information corresponding to the historical connection; migrating the uplink connection information and the downlink connection information to the first connection; and triggering the connection management process to close the historical connection.

The uplink connection information may refer to information sent by the client to the game service process in the server through the historical connection, and the downlink connection information may refer to information sent by the game service process in the server to the client through the historical connection. In this embodiment, the uplink and downlink connection information is migrated to the first connection, so that the communication between the first game service process and the client can be effectively recovered, and the first game service process and the client can conveniently acquire historical transmission data.

The historical connection is cut off when the line is broken, and then the client communicates with the game business process through a new connection, so that the historical connection does not need to be occupied continuously, and the server can recycle the historical connection to improve the utilization rate of connection resources. Further, the operation of closing the historical connection may be performed by a processor in the server. The operation of closing the historical connection may also be performed by a connection management process, in particular, when it is determined that a session exists, Connd closes the old connection, replaces it with the new connection, and migrates the upstream and downstream messages into the new connection.

Further, in some embodiments, in the process of recovering the second connection, the Connd may also close the original old connection and implement migration of the uplink and downlink messages when there is a session corresponding to the client and the second game service process.

The embodiment reasonably processes the old connection and the message corresponding to the old connection under the condition of recovering the new connection, can effectively recover the communication between the game business process and the client, and realizes effective disconnection reconnection.

In some embodiments, the disconnection reconnection method further comprises: if a heartbeat packet sent by the client is received, updating the heartbeat time of the corresponding session according to the heartbeat packet; the heartbeat packet is sent by the client regularly; if the heartbeat packet sent by the client is not received within a set time period, recovering the corresponding session, and setting the corresponding game account to be in an offline state; the game account is an account registered in the server by the client. Specifically, the client may send a heartbeat packet to the server periodically, and the server may determine that the client operates normally after receiving the heartbeat packet of the client, and may update the heartbeat time of the client. On the other hand, the server can monitor the heartbeat time of each client in real time, determine the heartbeat time which is not updated for a long time, clear the sessions corresponding to the heartbeat time, thoroughly cut off the connection between the client and the corresponding game business process after the sessions are cleared, and simultaneously set the player state corresponding to the client to be an offline state. Specifically, the server triggers the corresponding game logic when the heartbeat packet is not received within a timeout, for example, the state of the player is set to "leave the room" or "fight run".

In some embodiments, if the session is cleared and the client needs to re-enter the game, the session needs to be reestablished and a connection between the game service process and the client is established through the session. Further, the disconnection reconnection method further includes: if the session does not exist, establishing a session corresponding to the client; and reestablishing the connection between the first game service process and the client through the newly-established session.

After the connection between the first game service process and the client is reestablished, if the server receives a request sent by the client for connecting the second game service process, the second game service process can be selected, and the connection between the selected second game service process and the client is established.

After the corresponding relationship between the newly-built session and the first connection is established, the game server can manage the first connection through the newly-built session, and then repair or disconnect reconnection is carried out when the first connection fails.

The disconnection reconnection method provided by the embodiment can effectively ensure the communication between the first game service process and the client by newly establishing the session when the session does not exist, thereby ensuring the realization of disconnection reconnection.

In one embodiment, before the disconnection, the method further comprises: and controlling the first game business process to select the second game business process from at least one candidate game business process in a load balancing mode.

The candidate game business process may be a business process with an additional function in the server, and in addition, one function may correspond to at least one game candidate business process.

The load balance of the candidate game business processes can be realized by the first game business process, and the game business processes can be distributed more reasonably as far as possible in a load balancing mode when the load pressure of the game business processes is higher, so that the requests of the client sides are ensured to be responded in time. The implementation process of selecting the second game service process is as follows: when the first game business process receives a copy entering request sent by the client, the load condition of each candidate game business process is determined, and one candidate game business process with low load pressure is selected as a second game business process. On the other hand, there may be more than one second game service process, and therefore, the second game service process may select one of the candidate game service processes with small load pressure as another second game service process according to the incoming combat request of the client. In addition, as the number of the clients connected with the server is often more than one, the clients can be respectively allocated with the second game business process according to the requests of the clients.

In an embodiment, before the step of obtaining the connection address of the second connection if it is determined that the second connection to be restored exists, the method further includes: acquiring a historical connection state; the historical connection state is the connection state between the client and the at least one candidate game service process before disconnection; determining whether the second connection exists according to the historical connection state.

The specific process implemented by this embodiment may be: when the connection already exists, the first connection informs the client of the game state: for example, in a game hall, a room, a copy or a battle, it is determined whether the client has a slave connection according to the game state of the player (for example, if the player is in the copy or the battle, it indicates that the player is already on a certain Battlesvr, the slave connection exists, whereas if the player is in the room, it indicates that the player has not entered the copy or the battle, the slave connection does not exist at this time). When the slave connection exists, acquiring an address corresponding to the slave connection to prompt the client to restore the connection with the second game business process (for example, restoring the game state in the copy); when the slave connection does not exist, the game state of the client in the first game business process can be recovered through the first connection.

In some embodiments, the game player may have established a connection with only the first game service process before the disconnection, and not with the second game service process, at which time the connection address of the second connection does not exist. Therefore, in this embodiment, before acquiring the connection address of the second connection, it is determined whether the second connection exists, if the second connection exists, the connection address of the second connection is acquired through the session, and if the second connection does not exist, the game state of the client may be restored through the first connection without performing the operation of acquiring the connection address.

The disconnection reconnection method for the game provided by the above embodiment obtains the connection address of the slave connection when determining that the slave connection exists, and further prompts the client to recover the slave connection.

In one embodiment, after the step of obtaining the connection address of the second connection, the method further includes: and storing the connection address into a shared memory and/or a database.

For a server with storage, data related to client connection can be stored in persistent storage (e.g., a database) to avoid disconnection reconnection failure caused by loss of server state. For a server without a database, the connection state with the client can be stored in other manners, such as shared memory, so as to prevent the connection state from being asynchronous due to downtime of the server.

In one embodiment, if the server is the server where the game application program is located, the server communicates with a game service process in the server through an internal connection management process; if the server is an external platform, communicating with a game service process in the external platform through an external connection agent process; the external platform is independent of a server on which the game application resides. The game business process in the external platform may also be referred to as an external connection service.

The internal connection management process and the game business process can communicate through a shared memory, and the external connection agent process and the external connection service (including the game business process in the server) can communicate through an inter-process communication pipeline.

Further, in an embodiment, an application scenario of the disconnection reconnection method is shown in fig. 4, where the application scenario includes a client, a connection layer, and a game service layer. The client comprises a mobile device or a PC used by a user. The server side comprises a service layer and a connection layer from top to bottom. The service layer comprises a game service process, and specifically comprises Roomsvr and Battlesvr in the server and external connection service in an external platform; the connection layer manages the connection between the server and the client, and comprises Connd and Relaysvr which are respectively connected with Roomsvr and Battlesvr and Relaysvr which is connected with external connection service. The Connd and the game business process are communicated through Gobus, and the Relaysvr, the Roomsvr, the Battlesvr and the external connection service can be communicated through an inter-process communication pipeline. Communication between Roomsvr and Battlesvr (including with external connection services) is via Gobus or Gobusd.

Further, as shown in fig. 4, Roomsvr may provide the following functions: session management, server message processing, room listing, room management, load balancing management, state synchronization (with battessvr), client message processing; the Battlesvr can manage the copy system and the combat system and can also report the load, so that the Roomsvr selects proper Battlesvr through load balancing (the quantity of the Battlesvr can be more than one); the external connection service may provide the following functions: external connection management, load balancing management, message relay (which may be the relay of messages between Battlesvr and the client), protocol conversion, etc. (which implement the conversion with the protocol in the server). The function provided by the external connection service is similar to Roomsvr, the slave connection between the client and the Battlesvr can be recovered through the main connection between the client and the external connection service, and meanwhile, the external connection service can select a proper Battlesvr in a load balancing mode.

In one embodiment, a disconnection reconnection method is provided, which is applied to a client, and as shown in fig. 5, the method includes:

s501, sending a disconnection reconnection request to a connection management process of a server to trigger the server to determine a corresponding session; restoring the first connection according to the session; the first connection is formed by a first game business process in the server and a client through the connection management process; if the second connection to be recovered exists, acquiring a connection address of the second connection; the second connection is the connection between a second game business process in the server and the client, and the connection address is acquired by the first game business process from the second game business process.

S502, receiving the connection address returned by the connection management process through the first connection.

S503, restoring the second connection through the connection address.

The disconnection reconnection method provided in this embodiment is a disconnection reconnection method implemented from the perspective of a client, and for specific term explanation and implementation methods, reference may be made to the disconnection reconnection method from the perspective of a server. And will not be described in detail herein. According to the disconnection reconnection method, the reconnection states of the client at a plurality of entitlements are synchronized through inter-process communication under the condition that a plurality of connections exist, and the synchronization of player data on different game business processes can be effectively guaranteed.

In one embodiment, after the step of restoring the second connection through the connection address, the method further includes: sending a frame chasing request to the server; the frame tracking request is used for triggering the server to acquire a target data frame from at least one data frame; the at least one data frame is a data frame which meets a preset condition in a game fighting mode of a game application program; receiving the target data frame sent by the server, and calculating the context information of the target data frame; acquiring the state information of the game application program at the current moment from the server; and if the context information is not matched with the state information, continuously sending a frame chasing request to the server, repeating the steps of calculating the context information and acquiring the state information until the context information is matched with the state information, and recovering the game fighting mode.

The game fighting mode may refer to a mode in which characters between players or between a player and a game in a game application are in a fighting state. The game fighting mode is often controlled through an independent process, and at the moment, a plurality of connections exist in the processes of the client and the server, so that when the disconnection occurs, the plurality of connections need to be disconnected and reconnected.

In addition, the game fighting mode often adopts a frame synchronization technology, that is, the server does not participate in a complete logic calculation process, but only stores key data as a relay forwarding node and an arbitration node for synchronizing a plurality of clients. Thus, a data frame is a collection of game combat data, which may also be referred to as a combat frame, and may include player status, player operations, and the like. The data frames meeting the preset conditions can be key frames in the game application program, and can be data frames at certain key moments (for example, the player level changes). The target data frame may contain information about its neighbors.

For the battle of frame synchronization, the client cannot know what the current data frame of the server is, and therefore, the client needs to synchronize with the data frame in the server by frame chase. The peripheral access logic and the fighting logic of the game can be separated, and specifically, the client can send a frame chasing request to a second game service process in the server through a second connection to obtain a corresponding fighting frame, so that the fighting state in the client is recovered. Further, frame synchronization is mainly adopted for the fighting at present, so that only the fighting process can be subjected to frame chasing, and other processes can recover the game state according to a normal method (for example, a current data frame is acquired from a server, and corresponding game information is displayed on an interface of a client according to the data frame so as to recover the game state).

The game application program can generate data frames which are switched continuously according to the interactive operation of the client, so that a dynamic video form is formed, target data frames are data of partial data frames in the game application program, and the client needs to be synchronized with the current data frames in the server when the game state is recovered, so that the client can judge whether the data frames are synchronized with the client only if the data frames corresponding to the target data frames in the client are insufficient, and the data frames in front of or behind the data frames are required to be acquired. Wherein, the data frame at the front or the back moment is the context. Further, the target data frame may include description information of its neighboring data frame, and the specific frame operation algorithm may calculate the context information according to the target frame and the description information.

Further, for the client side frame chase, if the frame synchronization data amount is too large, some battle snapshot modes can be considered to store the periodic battle data, the overhead of disconnection reconnection of the client side is reduced, and the waiting time required by disconnection reconnection is reduced. Furthermore, the combat snapshot directly retains the stage combat details, so that each frame does not need to be chased, for example, one snapshot is provided every 1000 frames, if the frames need to be chased to 5122 frames, 5 snapshots can be obtained from 5000 frames, and then only 122 frames need to be chased from the 5000-frame snapshots, so that the processing mode can greatly shorten the time for the client to restore the game state.

According to the embodiment, in the frame synchronization game bureau, the player synchronizes to the instant context of battle in a mode of chasing frames step by step, and smoothly switches to the current game bureau to continue the game, so that the smoothness of the game application program running at the client side can be effectively improved, and the user experience is improved.

In one embodiment, before the step of sending the frame chase request to the server, the method further includes: sending an initialization request to the server; the initialization request is used for triggering the server to acquire initialization information of the game application program; and carrying out initialization operation according to the initialization information returned by the server.

Specifically, to restore the current battle context, the client needs to request the server for data of all key frames and run the operation of the duplicated key frames. When the client chases frames, the client requests the server for the initial information of battles, such as player information (camp, hero, initial blood volume, etc.) and random seeds, and then chases frames in sequence according to the sequence numbers. Because the data volume of a game is large (more than 5Mb may be possible), a mode of frame-chasing step by step is adopted, each time a request is sent to the server, only partial frames are requested, and after the calculation is finished, the next batch of data frames are requested. And the process is circulated until the state of the server is synchronized. By means of the frame-by-frame mode, the fighting recovery is achieved.

The method for disconnecting and reconnecting the game provided by the embodiment can be suitable for a frame synchronization game framework, provides a technical scheme of gradually chasing frames, enables the client to simulate the whole game process of the repeated game, and enables the server to only store key data frames without completely simulating the whole fighting process.

In one embodiment, a method for disconnection reconnection is provided, as shown in fig. 6, which includes the following steps regardless of the external platform:

s601, the client sends a disconnection reconnection request to a connection management process of the server.

S602, the connection management process determines the session corresponding to the client under the trigger of the disconnection reconnection request, and recovers the first connection between the first game service process and the client according to the session.

S603, the connection management process determines the historical connection between the first game service process and the client before disconnection according to the session, acquires the uplink connection information and the downlink connection information corresponding to the historical connection, migrates the uplink connection information and the downlink connection information into the first connection, and closes the historical connection.

S604, obtaining the historical connection state between the client and the candidate game service process before disconnection, and determining whether a second connection exists according to the historical connection state.

And S605, if the second connection does not exist, recovering the game process corresponding to the first connection in the client according to the first connection.

And S606, if the second connection is determined to exist, the first game service process acquires the connection address of the second connection from the second game service process through the communication channel.

S607, the connection management process returns the connection address to the client through the first connection.

And S608, the client recovers the second connection through the connection address.

And S609, the client sends a frame pursuit request to the server through the second connection, receives the target data frame sent by the server and calculates the context information of the target data frame.

S610, the client acquires the state information of the game application program at the current moment from the server.

S611, if the context information is not matched with the state information, the client continuously sends a frame chasing request to the server, and repeats the steps of calculating the context information and acquiring the state information until the context information is matched with the state information, and recovers the game process corresponding to the game fighting mode.

The application also provides an application scene, and the application scene applies the disconnection reconnection method. The application scenario does not consider an external platform, and as shown in fig. 7, the application of the disconnection reconnection method in the application scenario is as follows:

a) the game client (client for short), Roomsvr and Battlesvr are respectively initialized, and the Roomsvr and Battlesvr monitor the connection request sent by the client in real time (i.e. the disconnection reconnection request in case of disconnection).

b) Session and connection maintenance

The client side initiates a Websocket connection request to Connd, and the Connd brings the long connection into connection management and simultaneously informs a game service process in the server that a new client side connection comes. After receiving the notification of the Connd, the game service process searches for a session corresponding to the main connection (the connection between the client and the Roomsvr). If the session exists, the game service process notifies the Connd, the Connd restores the main connection between the client and the Roomsvr, at the moment, the Connd closes the original old connection, replaces the old connection with the new connection, and migrates the uplink and downlink messages to the new connection; if the session does not exist, a session is newly established and the corresponding relationship between the session and the connection is established (i.e. the client logs in the server again).

c) Multi-connection reconnection and combat chase frame

Roomsvr determines the game state of the client, determines whether the slave connection exists according to the game state, and responds slave connection information to the client.

If a slave connection exists, the slave connection information may include the address of the slave connection. The client acquires the connection address of the slave connection, is connected to the Battlesvr through the connection address, and initiates a frame tracing protocol to the Battlesvr. And repeating the frame tracking process continuously until the client is the same as the server, completing the disconnection reconnection at the moment, and entering a normal game flow.

If there is no slave connection, the slave connection information may be information indicating that there is no slave connection. At this point, the client may enter a normal game flow.

In the whole game process, along with the change of the game state of the player, Roomsvr and Battlesvr can synchronize the connection condition of the player in real time so as to ensure that the states of the players are consistent on different connections. If the inconsistency occurs, the state of the master connection is taken as the arbitration criterion.

The above embodiment is actually tested to simulate various conditions, such as network switching, network disconnection recovery, equipment top number, terminal-killing reconnection and the like. From the test results, it can be found that the disconnection reconnection method provided by the embodiment of the present invention can realize complete disconnection reconnection, so that the client can return to the room again in a short time (within a few seconds at most, the main time is spent on resource loading of the client). For the service logic, various conditions such as a game hall, a game room, a combat replica, actual combat and the like are simulated, meanwhile, simulation tests are carried out on the conditions of existence of subordinate connection, and through tests, the disconnection reconnection method provided by the embodiment of the invention can work normally and efficiently, complete reconnection of the client is realized, the game experience is ensured to be smooth, and the method can be suitable for various game service scenes. The method has the advantages of reliability, high efficiency, expandability and portability, and can be applied to solving the disconnection reconnection problem of various game servers.

In addition, the long TCP connection is mainly adopted in the traditional technology, the game server adopts C + + or other programming languages, and the long TCP connection cannot be well transplanted to the game server which is developed based on Golang and establishes connection through a Websocket protocol, and the disconnection reconnection method provided by the embodiment of the invention can be well applied to the scene.
