Description

Technical Field

[0001] The present disclosure relates to the field of communication technology, and in particular to a message communication method, apparatus, device, and medium. Background Art

[0002] In a distributed service, the entire cluster contains a large number of services, and network messages can be exchanged between any two of them. For example, in a distributed game service, objects in the game are called entities, and entities can be services, which means that network messages can be exchanged between any two entities. In other words, distributed services contain a large number of communication objects.

[0003] In related technologies, message communication between different communication objects in distributed services can be implemented using the Transmission Control Protocol (TCP). Due to the high resource overhead of TCP, an internal network topology is constructed to address this resource overhead. However, this method of message communication requires jumping through multiple internal communication objects, which can lead to problems such as message loss and message disorder, and still poses message reliability issues. In summary, the message communication method in distributed services cannot simultaneously solve the problem of high resource overhead and ensure message reliability. Summary of the Invention

[0037] The following describes embodiments of the present disclosure in more detail with reference to the accompanying drawings. Although certain embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be construed as limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the present disclosure. It should be understood that the drawings and embodiments of the present disclosure are for illustrative purposes only and are not intended to limit the scope of protection of the present disclosure.

[0038] It should be understood that the various steps described in the method embodiments of the present disclosure may be performed in different orders and / or in parallel. In addition, the method embodiments may include additional steps and / or omit the steps shown. The scope of the present disclosure is not limited in this respect.

[0039] As used herein, the term "including" and its variations are open-ended, i.e., "including but not limited to." The term "based on" means "based, at least in part, on." The term "one embodiment" means "at least one embodiment," the term "another embodiment" means "at least one additional embodiment," and the term "some embodiments" means "at least some embodiments." Other terms are defined in the following description.

[0040] It should be noted that the concepts of "first" and "second" mentioned in this disclosure are only used to distinguish different devices, modules or units, and are not used to limit the order or interdependence of the functions performed by these devices, modules or units.

[0041] It should be noted that the modifications of "one" and "multiple" mentioned in the present disclosure are illustrative rather than restrictive, and those skilled in the art should understand that unless otherwise clearly indicated in the context, they should be understood as "one or more".

[0042] The names of the messages or information exchanged between multiple devices in the embodiments of the present disclosure are only used for illustrative purposes and are not used to limit the scope of these messages or information.

[0043] In related technologies, message communication between different communication objects in a distributed service can be achieved through the Transmission Control Protocol (TCP). TCP is a common protocol used to ensure message reliability. It is applicable to mutual communication between any two network hosts or services. TCP establishes a connection through a three-way handshake. Each TCP segment has a sequence number. By using the sequence number, the TCP layer can deliver the information in the received segment to the application layer in the correct order, and the sender detects lost transmission data and retransmits the data to ensure reliability. However, TCP connections have a large resource overhead. For a server, the maximum number of TCP connections that can be supported is 65535. In a distributed service, any two internal service processes can communicate with each other. Assuming that a server deploys 50 service processes and the entire cluster has a total of 10,000 service processes, when using TCP to connect all services, a server needs to support 500,000 connections.

[0044] In order to solve the resource overhead problem, the distributed game service architecture can usually ensure the reliability of messages through reasonable network topology design combined with TCP. Figure 1This is a schematic diagram of a message communication technique in the related art. The diagram shows the network topology structure in a distributed game service. A multi-layer network structure is constructed using router and multi-port forwarder processes. Two connected processes directly use TCP connections, and two game processes communicate messages through multiple layers of relays. For example, in the diagram, between game process 11 and game process 21, the following sequence follows: game process 11 -> router 1 -> multi-port forwarder -> router 2 -> game process 21. However, after constructing the internal network topology, message communication must jump through multiple internal communication objects (e.g., processes). Multiple message communications between two communication objects can lead to message loss and message disarray due to factors such as a dynamic increase in the number of internal communication objects, server downtime, or network failures in the computer room. For example, messages can be lost due to disconnection and reconnection, or messages can be routed to the wrong link after capacity expansion and the addition of new routers. This still poses message reliability issues. In summary, the message communication method in distributed services cannot simultaneously address the high resource overhead and guarantee message reliability.

[0045] In order to solve the above problems, an embodiment of the present disclosure provides a message communication method, which is introduced below in conjunction with specific embodiments.

[0046] Figure 2 This is a flow chart of a message communication method provided by some embodiments of the present disclosure. The method can be executed by a message communication device, wherein the device can be implemented using software and / or hardware and can generally be integrated into an electronic device. Figure 2 As shown, the method is applied to the sending end within the distributed service, including:

[0047] Step 101: Create connection establishment information with the receiving end before sending the initial message packet, and send a communication establishment request to the receiving end, wherein the communication establishment request includes the initial message packet and the connection establishment information, and the sending end and the receiving end communicate through a preset protocol.

[0048] The message communication method of the embodiments of the present disclosure can be executed by a communication object within a distributed service that acts as a sender. A communication object is a broad term that can include objects capable of message communication, such as network hosts and entities within a game. Any communication object within a distributed service can serve as a sender in the embodiments of the present disclosure, and any other communication object communicating with that communication object can serve as a receiver in the embodiments of the present disclosure.

[0049] The initial message packet may be the first message packet that the sender needs to send to the receiver. Due to the internal communication of the distributed service, all message contents are credible. Therefore, the two communicating objects can also send message packets before establishing a communication connection, but the message packets will not be stored. The connection establishment information can be understood as unilateral information created by the sender when it determines that it does not have an established connection with the current receiver. It can include a connection sequence number and a connection timestamp, and store it locally. The preset protocol can be a new protocol in the embodiment of the present disclosure that can establish a communication connection without handshaking, and can be a custom protocol.

[0050] In an embodiment of the present disclosure, the sending end within the distributed service can create connection establishment information with the receiving end before sending the initial message packet and cache it locally, add the initial message packet and connection establishment information to the communication establishment request and send it to the receiving end through a preset protocol to enable the receiving end to perform subsequent operations.

[0051] Step 102: Acquire session information created by the receiving end based on the connection establishment information, and establish a communication connection with the receiving end based on the session information.

[0052] The session information may be created by the receiving end based on the communication establishment request of the sending end, and is used to indicate the session ID of the subsequent communication connection established between the sending end and the receiving end. The session information is created by the receiving end and sent to the sending end to establish the communication connection.

[0053] Specifically, after the receiving end receives the communication establishment request, it can store the connection establishment information and confirm the need to establish a communication connection with the receiving end based on the connection establishment information. It can then create a session information and return the session information to the sending end; after the sending end receives the session information, it can establish a session with the receiving end based on the session information, that is, establish a communication connection link between the sending end and the receiving end, and subsequently message communication can be carried out based on this link.

[0054] For example, Figure 3 A schematic diagram of establishing a communication connection provided in some embodiments of the present disclosure, such as Figure 3As shown in the figure, seq represents the sequence number of the message packet, and ack represents the confirmation packet, indicating that the sent data has been confirmed to be received correctly, and the sender and the receiver can communicate through routing; the process of establishing a communication connection may include: the sender sends a communication establishment request including the initial message packet seq1 and the connection establishment information to the receiver; the receiver replies with the confirmation packet ack1 and the session information created based on the connection establishment information to the sender; the sender establishes a communication connection with the receiver based on the session information, and then the sender can send subsequent message packets seq3 and seq4 to the receiver based on the communication connection, and receive corresponding confirmation packets ack3 and ack4; during the communication establishment process, the sender can also send message packet seq2 to the receiver, and receive the corresponding confirmation packet ack2.

[0055] In this solution, since the content of all messages within the distributed service is trustworthy, the process of establishing a communication connection can be simplified. Unlike TCP, there is no need for a three-way handshake. Instead, the connection is quickly established when the message is actually sent, which improves the efficiency of establishing the communication connection.

[0056] Step 103: If it is determined that the initial message packet is lost, the initial message packet is resent to the receiving end based on the session information.

[0057] After sending the initial message packet, if the sending end determines that the duration of not receiving the confirmation packet of the initial message packet is greater than the preset duration, it is determined that the initial message packet is lost. The initial message packet can then be resent to the receiving end based on the session information. If the retransmitted message packet is still lost after the retransmission, multiple retransmissions can be performed. In the case of multiple retransmissions, the above-mentioned preset duration is continuously extended until the confirmation message packet is successful.

[0058] For example, Figure 4 A schematic diagram of message retransmission is provided for some embodiments of the present disclosure. In the figure, seq represents the sequence number of the message packet, ack represents the confirmation packet, and the request to establish a session is the above-mentioned communication establishment request. The sending end sends a communication establishment request including an initial message packet seq1 and connection establishment information to the receiving end. The initial message packet seq1 confirms packet loss; the receiving end replies with session information to the sending end; the sending end establishes a communication connection with the receiving end based on the session information, and then the sending end can resend the initial message packet seq1 to the receiving end based on the communication connection.

[0059] In the above scheme, the reliability of message communication is guaranteed by the message retransmission mechanism.

[0060] In some embodiments, the message communication method may further include: if it is determined that the initial message packet is lost before the session information is obtained, resending the communication establishment request to the receiving end.

[0061] If the sending end determines that the initial message packet is lost before step 102, since the communication connection with the receiving end has not yet been established, message retransmission is prohibited. Instead, the sending end triggers the retransmission of the communication establishment request to the receiving end, thereby resending the initial message packet and establishing the communication connection. That is, for the sending end, there are two states: a connecting state and a successful connection state. The connecting state means that the sending end has created the connection establishment information but has not yet obtained the session information to establish the communication connection. The successful connection state means that the communication connection with the receiving end has been established. In the connecting state, message retransmission is prohibited, while in the successful connection state, message retransmission is allowed.

[0062] The message communication solution provided by the embodiment of the present disclosure is that the sending end inside the distributed service creates connection establishment information with the receiving end before sending the initial message packet, and sends a communication establishment request to the receiving end, wherein the communication establishment request includes the initial message packet and the connection establishment information, and the sending end and the receiving end communicate through a preset protocol; obtains the session information created by the receiving end based on the connection establishment information, and establishes a communication connection with the receiving end based on the session information; if it is determined that the initial message packet is lost, the initial message packet is resent to the receiving end based on the session information. The above technical solution is adopted, by setting a preset protocol inside the distributed service, so that the sending end and the receiving end can quickly establish a communication connection when sending a message packet through the preset protocol, without the need for multiple handshakes, thereby improving the efficiency of establishing a communication connection, and avoiding the problem of high resource overhead caused by the use of the TCP protocol in related technologies, and when the message packet is lost, the message packet can be successfully sent by retransmission, thereby ensuring the reliability of message communication and guaranteeing the message reliability on the basis of solving the resource overhead problem.

[0063] In some embodiments, because the sending and receiving ends communicate via a preset protocol, embodiments of the present disclosure may redesign the structure of the message packet, of which the initial message packet is one. The basic header information of the message packet includes the protocol number, a tag field, a communication object identifier, and a peer process identifier. The tag field includes a first field indicating whether to retransmit and a second field indicating whether the message is the minimum sequence number. The message packet header includes connection establishment information, session information, and a message sequence number. The connection establishment information includes a connection timestamp and a connection sequence number.

[0064] For example, Figure 5 A schematic diagram of a message packet provided in some embodiments of the present disclosure, such as Figure 5As shown, the first field in the tag field of the basic packet header marks whether the message is retransmitted. Different routing rules can be used for retransmitted and non-retransmitted message packets to avoid a long period of retransmission and failure to deliver due to a certain routing link being unavailable; the second field marks whether the message has the smallest sequence number; the mark of whether the smallest sequence number indicates that the current message has the smallest sequence number and has not received an acknowledgment character (ACK). The first message packet sent must be marked with the smallest sequence number, and the receiving end processes the message packets in sequence starting from the smallest sequence number; the communication object identifier (ID) and the peer process identifier (ID) are used to route the message packet. The communication object identifier can be identification information that uniquely represents the receiving end, and the peer process identifier can be an identifier that uniquely represents the process of intermediate message forwarding. The message packet header includes connection establishment information, session information, and message sequence number. The session information can be a session identifier that uniquely represents the communication connection established between the sending end and the receiving end, and the message sequence number can uniquely represent the processing order of the current message packet.

[0065] In the above solution, by redesigning the header of the message packet within the distributed service, it is applicable to the communication connection of the above embodiment, which helps to solve subsequent problems during the transmission of the message packet.

[0066] In some embodiments, the message communication method may further include: if the duration of not sending subsequent message packets is greater than a first duration threshold, and / or a notification is received from the message routing end that the receiving end does not exist, closing the communication connection with the receiving end.

[0067] The subsequent message packet is a message packet sent after the sender establishes a communication connection with the receiver, and is used to distinguish it from the initial message packet. The first duration threshold can be a duration threshold set for the sender, which can be set according to actual circumstances. For example, the first duration threshold can be 5 minutes. The message routing end can be a routing end that relays messages between the sender and the receiver. In the embodiments of the present disclosure, the sender and the receiver can communicate messages directly or through the message routing end.

[0068] If the sending end determines that no subsequent message packets have been sent within the first duration threshold, i.e., that no messages have been sent for a period of time, it can proactively close the communication connection with the receiving end and send a closure notification to the receiving end, prompting the receiving end to also close the communication connection. Alternatively, if the message routing end detects that the receiving end has gone offline, it can trigger a notification to the sending end indicating that the receiving end no longer exists. Upon receiving this notification, the sending end can close the communication connection with the receiving end. Optionally, the sending end and the receiving end can clear the communication connection after closing it.

[0069] In the above solution, the sending end can actively or passively disconnect the communication connection with the receiving end at a certain time to save resource overhead.

[0070] In some embodiments, the message communication method may further include: during the migration process of the receiving end from the initial process to the target process, sending the target message packet to the initial process and the target process, wherein the initial process forwards the first part of the message packet in the target message packet to the target process after receiving it, and the receiving end suspends message processing and confirmation reply during the migration process; if it is confirmed that the migration process has failed and the second part of the message packet in the target message packet is lost, the target message packet is resent to the initial process.

[0071] Within a distributed service, a process can include multiple communication objects. The processes containing these communication objects support migration. The initial process represents the receiving end's process before migration, while the target process represents the receiving end's process after migration. Target message packets can be any number of message packets sent by the sender during the migration of the receiving end's process.

[0072] Specifically, during the migration process of the receiving end from the initial process to the target process, the sending end sends the first part of the target message packet to the initial process through the old route, and sends the second part of the target message packet to the target process through the new route. After receiving the first part of the message packet in the target message packet, the initial process can directly forward it to the target process. After receiving the second part of the message packet, the receiving end in the target process can submit it to the protocol layer for caching; if the sending end confirms that the migration process has failed and executes the rollback, the second part of the message packet sent to the target process may be lost. Since the receiving end can suspend message processing and reply to the confirmation packet during the migration process, the sending end determines that the duration of the confirmation packet of the second part of the message packet is greater than the preset duration, then it can be determined that the second part of the message packet is lost, and the second part of the message packet is resent to the initial process.

[0073] For example, Figure 6 A schematic diagram of process migration provided in some embodiments of the present disclosure, such as Figure 6 As shown in the figure, the migration process of the receiving end process is shown. The receiving end process migrates from the initial process to the target process. During the migration process, the sender sends part of the message to the initial process and part of the message to the target process. The initial process directly forwards the received part of the message to the target process. The receiving end can suspend message processing and reply to confirmation packets during the migration process, and resume message processing and reply to confirmation packets after the migration is completed.

[0074] In gaming scenarios, service migrations occur. For example, an object or service can migrate from one physical server to another. For network communication, this is conceptually similar to the dynamic change of the other party's address. In the above solution, by pausing message processing and confirming responses when the communicating party undergoes process migration, a retransmission mechanism can be used to ensure message reliability in the event of a migration failure.

[0075] Figure 7 This is a flow chart of another message communication method provided by some embodiments of the present disclosure. The method can be executed by a message communication device, wherein the device can be implemented using software and / or hardware and can generally be integrated into an electronic device. Figure 7 As shown, the method is applied to the receiving end within the distributed service, including:

[0076] Step 701: Receive a communication establishment request sent by a sending end. The communication establishment request includes an initial message packet and connection establishment information. The connection establishment information is created by the sending end before sending the initial message packet. The sending end and the receiving end communicate through a preset protocol.

[0077] Any communication object in a distributed service can serve as a receiving end in accordance with an embodiment of the present disclosure, and another communication object communicating with the communication object can serve as a sending end in accordance with an embodiment of the present disclosure.

[0078] In an embodiment of the present disclosure, the sending end within the distributed service can create connection establishment information with the receiving end before sending the initial message packet and cache it locally, add the initial message packet and connection establishment information to the communication establishment request and send it to the receiving end through a preset protocol; the receiving end can receive the communication establishment request.

[0079] Step 702: Create session information based on the connection establishment information, and return the session information to the sending end, so that the sending end establishes a communication connection with the receiving end based on the session information.

[0080] After receiving the communication establishment request, the receiving end can store the connection establishment information and confirm the need to establish a communication connection with the receiving end based on the connection establishment information. Then, it can create a session information and return the session information to the sending end. After receiving the session information, the sending end can establish a session with the receiving end based on the session information, that is, establish a communication connection link between the sending end and the receiving end, and subsequently message communication can be carried out based on this link.

[0081] Step 703: Receive the initial message packet resent by the sending end based on the session information when determining that the initial message packet is lost.

[0082] After sending the initial message packet, if the sending end determines that the duration of not receiving the confirmation packet of the initial message packet is greater than the preset duration, it is determined that the initial message packet is lost. The initial message packet can then be resent to the receiving end based on the session information. If the retransmitted message packet is still lost after the retransmission, multiple retransmissions can be performed. In the case of multiple retransmissions, the above-mentioned preset duration is continuously extended until the confirmation message packet is successful.

[0083] The message communication solution provided by the embodiment of the present disclosure is that the receiving end inside the distributed service can receive the communication establishment request sent by the sending end, and the communication establishment request includes an initial message packet and connection establishment information. The connection establishment information is created by the sending end before sending the initial message packet. The sending end and the receiving end communicate through a preset protocol; create session information based on the connection establishment information, and return the session information to the sending end so that the sending end establishes a communication connection with the receiving end based on the session information; receive the initial message packet resent by the sending end based on the session information when determining that the initial message packet is lost. The above technical solution is adopted, by setting a preset protocol inside the distributed service, so that the sending end and the receiving end can quickly establish a communication connection when sending a message packet through the preset protocol, without the need for multiple handshakes, thereby improving the efficiency of establishing a communication connection, and avoiding the problem of high resource overhead caused by the use of the TCP protocol in related technologies. In addition, when the message packet is lost, the message packet can be successfully sent by retransmission, thereby ensuring the reliability of message communication and guaranteeing the message reliability on the basis of solving the resource overhead problem.

[0084] In some embodiments, the message communication method may further include: if the duration of not receiving subsequent message packets from the sender is greater than a second duration threshold, sending a detection message to the sender through the message routing end; if a notification that the sender does not exist is received from the message routing end, clearing the residual connection between the sender and the sender.

[0085] Among them, the second duration threshold can be a duration threshold set for the receiving end, which can be set according to actual conditions. The message routing end can be a routing end that transfers messages between the sending end and the receiving end. In the embodiment of the present disclosure, the sending end and the receiving end can communicate messages directly, or can communicate messages through the message routing end. The detection message can be a message used to determine whether the local end can successfully exchange information packets with the other end, and then determine whether there is a problem with the connection with the other end based on the returned information. For example, the detection message can use the ping command. The residual connection can be a communication connection that only exists unilaterally for the receiving end when the sending end directly closes the communication connection with the receiving end when it goes offline, and the close notification sent to the receiving end is not delivered.

[0086] Specifically, if the receiving end does not receive subsequent message packets from the sending end within a continuous period exceeding the second time threshold, it can send an activity detection message to the sending end, and the activity detection message is forwarded through the message routing end; if the receiving end receives a notification from the message routing end that the sending end does not exist, it can be determined that the sending end has gone offline and cleared the communication connection, and at this time the residual connection between the sending end and the sending end can be cleared.

[0087] For example, Figure 8 A schematic diagram of residual connection processing provided in some embodiments of the present disclosure, such as Figure 8 As shown in the figure, the process of residual connection processing by the receiving end can be specifically included: the receiving end can update the activity time, that is, the time when the sending end last sent a message; the close notification sent to the receiving end after the sending end goes offline is lost; if the receiving end does not receive subsequent message packets from the sending end for a duration greater than the second duration threshold, it is determined that the sending end has been inactive for a long time and a detection message can be sent to the sending end; when the receiving end receives a notification from the message routing end that the sending end does not exist, the residual connection between the receiving end and the sending end can be cleared.

[0088] In the above scheme, when the sending end actively closes the communication connection and the close notification is lost, the receiving end can clean up the residual connection through liveness detection, thereby avoiding message loss caused by unilateral retention of the communication connection and saving resource overhead.

[0089] In some embodiments, the message communication method may further include: if it is determined that there is a retransmission packet among the multiple processed first message packets, clearing the current communication connection at a preset time, wherein the preset time is greater than or equal to the sum of the connection time and the delay time of the current communication connection. Optionally, the message communication method may further include: if no local communication connection exists when the second message packet is received, determining whether the second message packet is an initial network residual packet; if the second message packet is an initial network residual packet, sending a confirmation request for the initial network residual packet to the sending end so that the sending end confirms the initial network residual packet; determining that the initial network residual packet is a target network residual packet based on the confirmation information returned by the sending end, and discarding the target network residual packet.

[0090] The first message packet may be a message packet that has been processed by the receiving end, and the retransmission packet may be a message packet that is retransmitted after confirming that a message packet is lost. The retransmission packet here refers to a retransmission packet among multiple first message packets. If a message packet is a retransmission packet, its basic packet header information has a first field marked as retransmission. The connection time of the current communication connection can be extracted from the connection timestamp of the basic packet header information in the first message packet. The delay time can be a preset fixed clearing time that can be set according to actual conditions. For example, the delay time can be set to 10 seconds. The preset time can be the specific time when the current communication connection is cleared or destroyed. The preset time is a time after the connection time exceeds the delay time, that is, the current communication connection is cleared at least after the connection time plus the delay time.

[0091] The second message packet can be a message packet received by the receiving end when there is no local communication connection, a message packet received by the receiving end after the current communication connection is cleared, or a message packet at another time. The initial network residual packet can be a preliminarily determined network residual packet, and the target network residual packet can be the final network residual packet determined by the sending end. For network residual packets, when a message packet is sent and no confirmation packet is received within a preset time, it can trigger the retransmission of the message packet, that is, the sending of a retransmission packet of the message packet. At this time, the message packet sent for the first time is not necessarily lost, and may still be in a link node of the cluster due to process or machine lag, etc., and has not yet been delivered. At this time, the retransmission packet of the message packet may reach the receiving end faster through a different link and be processed normally; in more extreme cases, the current communication connection is fully processed and closed and cleared, and the information packet sent for the first time is sent to the receiving end. This part of the message packet is called a network residual packet. Since the network residual packet received by the receiving end before the communication connection is closed and cleared can be directly identified and discarded, while the network residual packet received by the receiving end after the communication connection is closed and cleared cannot be directly identified and processed, the network residual packet in the embodiment of the present disclosure refers to a network residual packet that cannot be identified and processed.

[0092] Specifically, in order to process network residual packets, the receiving end can set a delayed clearing mechanism for the current communication connection with the sending end. Since network residual packets may only appear when there are retransmission packets, for multiple processed first message packets, it can be determined whether there are retransmission packets. Specifically, it can be determined whether to mark the retransmission based on the first field of the basic packet header information in each first message packet. If it is determined that there is no retransmission packet, the current communication connection can be directly closed and cleared, and the delayed clearing mechanism will not be triggered; if it is determined that there is a retransmission packet, the current communication connection can be cleared at a preset time, that is, at least after the connection time plus the delay time. For example, the connection time of the current communication connection is 10 seconds. If it is determined that there is a retransmission packet and the delay time is 10 seconds, the current communication connection will be cleared at least after 20 seconds.

[0093] When the receiving end receives the second message packet when there is no communication connection locally, it can determine whether it is the initial network residual packet based on the receiving time in the second message packet. If so, it sends a confirmation request for the initial network residual packet to the sending end so that the sending end confirms the initial network residual packet. If the confirmation information returned by the sending end indicates that the communication connection of the initial network residual packet does not exist, it can be determined that the initial network residual packet is the target network residual packet and the target network residual packet is discarded; if the confirmation information returned by the sending end indicates that the communication connection of the initial network residual packet exists, the second message packet can be processed; if it is determined that the second message packet is not the initial network residual packet, session information can be created to create a new communication connection with the sending end.

[0094] Optionally, determining whether the second message packet is an initial network residual packet includes: if the reception time of the second message packet is after the corresponding target time, determining that the second message packet is an initial network residual packet; otherwise, determining that the second message packet is not an initial network residual packet, and the target time is the sum of the connection time and the delay time in the second message packet.

[0095] When the receiving end determines whether the second message packet is an initial network residual packet, it can be determined based on the receiving time and target time of the second message packet. The target time can be the sum of the connection time obtained by extracting the connection timestamp of the basic packet header information in the second message packet and the preset delay time, that is, the time after the connection time passes the delay time; if the receiving time of the second message packet is after the above-mentioned target time, that is, outside the connection time plus the delay time, it is determined that the second message packet is received after its corresponding communication connection is cleared, and it is determined to be an initial network residual packet; if the receiving time of the second message packet is before the above-mentioned target time, that is, within the connection time plus the delay time, it means that no communication connection has been established before, and it can be determined that it is not an initial network residual packet.

[0096] For example, Figure 9 A schematic diagram of residual data packet processing provided in some embodiments of the present disclosure, such as Figure 9As shown in the figure, the processing process of the residual data packet at the receiving end is shown, specifically including: the sending end sends a packet, the connection time is T, it is blocked in route 1, and then resends and subsequently sends packets, which are transferred through route 2. The receiving end does not need to verify to establish a communication connection; the sending end sends a close instruction to the receiving end. After the receiving end closes the communication connection, due to the resend packet, it needs to delay until T+X time to clear the communication connection, X is the delay time; then the network residual message blocked by route 1 is continued to be forwarded. After the receiving end receives the message packet, the connection time of the message packet is T. If it is determined that the reception time of the message packet is greater than T+X, it may be a network residual packet, that is, it exceeds the cleaning time and needs to be verified. A confirmation request can be sent to the sending end. If the sending end determines that the message packet has no connection verification and fails, the receiving end can confirm that the message packet is a network residual packet and discard it.

[0097] This solution does not require multiple handshakes to establish and disconnect connections. To address the problem of unrecognizable residual message packets, the above solution sets up a delay cleaning mechanism. According to the reception time of the message packet, the corresponding connection time and the delay time, the possible residual data packets can be judged, and the unrecognizable network residual packets can be finally determined for processing through confirmation by the sender, thereby solving the problem of processing unrecognizable network residual packets.

[0098] In some embodiments, the message communication method may further include: suspending message processing and confirmation reply during the migration process from the initial process to the target process at the receiving end; and starting message processing and confirmation reply after the migration process ends.

[0099] During the migration process from the initial process to the target process, the receiving end can suspend the message processing and confirmation reply process; the sending end sends the first part of the target message packet to the initial process via the old route, and sends the second part of the target message packet to the target process via the new route. After receiving the first part of the target message packet, the initial process can directly forward it to the target process. After receiving the second part of the message packet, the receiving end in the target process can submit it to the protocol layer for caching. After the migration process is completed, the message processing and confirmation reply process can be started. If the sending end confirms that the migration process has failed and performs a rollback, the second part of the message packet sent to the target process may be lost. Since the receiving end can suspend message processing and confirmation packet reply during the migration process, the sending end determines that the duration of the confirmation packet of the second part of the message packet is greater than the preset duration. In this case, it can be determined that the second part of the message packet is lost and the second part of the message packet is resent to the initial process.

[0100] In the above solution, by suspending message processing and confirming responses when the communication object performs process migration, the reliability of the message can be guaranteed through a retransmission mechanism when the migration fails.

[0101] In this solution, in distributed services, connections between different communication objects can be established without delay based on internal network characteristics and preset protocols, and the header structure of the message packet can be redesigned to solve the problem of network residual packets under the fast connection establishment method. It not only solves the message reliability problem between internal services with less resource overhead, but also solves the problem of migration of communication objects between processes.
