[0033] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0034] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the terms used in this way are interchangeable where appropriate, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0035] For ease of understanding, some contents involved in the embodiments of the present application are described below:

[0036] MTU refers to the maximum data packet size that can be passed on a certain layer of a communication protocol.

[0037] When the user terminal establishes a TCP connection with the network server, it sends its own MTU to the other party through the TCP three-way handshake message, and selects the smaller MTU from the terminal MTU and the network server MTU as the MTU used for network data transmission after the link connection is successful. The size of the data packet sent by the user terminal and the network server will not exceed the negotiated MTU, that is, when the size of the data to be sent by the user terminal and the network server exceeds the negotiated MTU, the data will be sent in fragments to ensure that the data packet sent will not exceed the negotiated MTU. On the other hand, after the terminal and the network server negotiate the MTU, if the data packet received from the other end is larger than the MTU, the data packet will be discarded.

[0038] In addition, after the terminal and the network server negotiate the MTU, if the network server needs to send a data packet larger than the negotiated MTU to the terminal in a specific scenario, the network server will send the data packet to the terminal, but the terminal will discard the data packet based on the negotiated MTU.

[0039] The data processing method, device and electronic device provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.

[0040] like Figure 1 As shown, a data processing method in an embodiment of the present application, which is executed by a terminal, includes:

[0041] Step 101: upon receiving a first data packet sent by a network side device, and the size of the first data packet is larger than a first maximum transmission unit MTU, a negotiation message is sent to the network side device.

[0042] Here, the first MTU is the MTU negotiated by the terminal and the network side device through the TCP three-way handshake. The terminal sends and receives data packets according to the first MTU, and the network side device also sends and receives data packets according to the first MTU. The first data packet is sent by the network side device when a large data packet (abnormal data packet) needs to be sent in a specific scenario. The specific scenario can be understood as an abnormal data packet sending scenario. At this time, the size of the data packet sent by the network side device is not limited by the first MTU.

[0043] When the terminal receives the first data packet and learns that there is a need to transmit a large data packet, it sends a negotiation message to the network-side device to negotiate an MTU that can complete the transmission of the large data packet based on the abnormal data packet.

[0044] Step 102: Receive a negotiation response message sent by the network side device according to the negotiation message; wherein the negotiation response message is used to indicate a second MTU, and the second MTU is greater than the first MTU.

[0045] After step 101, after receiving the negotiation information sent by the terminal, the network side device can determine a second MTU larger than the first MTU according to the indication of the negotiation message, and inform the terminal of the second MTU through a negotiation response message. The terminal can then receive the negotiation response message according to step 102 and obtain the second MTU.

[0046] Step 103: When a second data packet sent by the network side device is received and the size of the second data packet is less than or equal to the second MTU, save the second data packet.

[0047] In this step, the terminal can save the second data packet sent by the network side device based on the second MTU learned in step 102. Of course, the terminal can discard the data packet larger than the second MTU.

[0048] In this way, according to the above steps 101-103, after receiving the first data packet larger than the first MTU, the terminal will send a negotiation message to the network side device, and then receive the negotiation response message including the second MTU sent by the network side device according to the negotiation message, and when receiving the second data packet sent by the network side device, the second data packet is saved. That is to say, the terminal can save the second data packet sent by the network side device that is less than or equal to the second MTU based on the negotiated second MTU, thereby ensuring the transmission of data packets larger than the first MTU between the network side device and the terminal.

[0049] The network side device may be a network server. At this time, the first data packet is a data packet received by the network server from a third-party server that is larger than the first MTU, or a data packet of the network server itself that is larger than the first MTU.

[0050] It should be understood that, in this embodiment, the process of the terminal and the network side device negotiating the first MTU through the TCP three-way handshake includes steps 1-2:

[0051] 1. The terminal initiates a data connection establishment to the network side device.

[0052] That is, the terminal sends a synchronization sequence number (SYN) to the network side device for the first TCP handshake, which carries the size of the MTU supported by itself. This MTU is the maximum data packet size that the terminal can handle, so as to establish a data connection with the network side device.

[0053] 2. The network-side device responds to the data connection and negotiates the MTU size.

[0054] That is, after the network server receives the SYN from the terminal, it will parse out the MTU size carried by the SYN sent by the terminal, and set this value as its upstream MTU size (also called the sending MTU size), that is, the size of the data packet sent by the network side device to the terminal will not exceed the terminal's processing capacity. At the same time, the network side device sends [SYN, ACK] to the terminal for the second TCP handshake, which carries the downstream MTU size supported by the network side device (also called the receiving MTU size). When the terminal receives the downstream MTU size of the network side device, it also sets this value as its upstream MTU size, and replies ACK to the network side device for the third TCP handshake. Finally, a TCP connection is established between the terminal and the network server, and the upstream and downstream MTU sizes, that is, the first MTU, are negotiated.

[0055] Optionally, in this embodiment, the negotiation message includes at least one of the following:

[0056] the first data packet;

[0057] A third MTU, where the third MTU is determined by the size of the first data packet determined by the terminal.

[0058] That is, after receiving the first data packet sent by the network side device, the terminal can send the first data packet to the network side device so that the network side device can determine the size of the first data packet by parsing and further determine the second MTU. After receiving the first data packet sent by the network side device, the terminal can also determine the size of the first data packet by parsing the data packet and determine the third MTU based on the determined size of the first data packet, such as using the determined size of the first data packet as the third MTU so that the network side device can determine the second MTU based on the third MTU.

[0059] Among them, after the terminal sends a negotiation message (such as the negotiation message includes a first data packet), the terminal may not save the first data packet and wait for the network side device to send the first data packet again as a second data packet; or, after the terminal sends a negotiation message (such as the negotiation message includes a third MTU), the terminal may directly save the first data packet, and the second data packet sent by the network side device is different from the first data packet.

[0060] Optionally, after obtaining the third MTU, the terminal sets the third MTU as the reverse MTU size of the terminal. Afterwards, the terminal sends a negotiation message to the network side device.

[0061] Optionally, in this embodiment, the second MTU is one of the third MTU and the fourth MTU;

[0062] The fourth MTU is determined by the size of the first data packet determined by the network side device.

[0063] Optionally, after receiving the first data packet sent by the terminal, the network side device determines the size of the first data packet, that is, the fourth MTU, by parsing, and uses the fourth MTU as the second MTU.

[0064] Optionally, after receiving the third MTU sent by the terminal, the network side device directly uses the third MTU as the second MTU.

[0065] Optionally, the network side device selects one of the third MTU and the fourth MTU as the second MTU. For example, the minimum value or the maximum value of the third MTU and the fourth MTU is selected as the second MTU.

[0066] Optionally, after obtaining the second MTU, the network side device sets the second MTU as the reverse MTUsize of the network side device. Afterwards, the network side device sends the second data packet to the terminal.

[0067] In addition, to prevent the network side device from setting the reverse MTU size too frequently, optionally, in this embodiment, the network side device determines the second MTU based on the maximum third MTU or the first data packet received in the set time length t or number of times n. The values ​​of t and n can be predefined or configured.

[0068] Of course, if the network side device cannot process the first data packet, the reverse MTU size is not set.

[0069] Optionally, in this embodiment, after receiving the negotiation response message, the terminal sets the reverse MTU size of the terminal based on the second MTU indicated by the negotiation response message. The second MTU is the reverse MTU size recognized by the network side device.

[0070] Optionally, in this embodiment, the second data packet is transmitted within a valid time of the second MTU.

[0071] That is, the second MTU has a specific validity period. The terminal compares the size of the data packet received within the validity period with the second MTU, and saves the data packet whose size is less than or equal to the second MTU.

[0072] Optionally, in this embodiment, the method further includes:

[0073] In the case where the first field of the negotiation response message is set to be empty or 0, and / or a third data packet is received outside the valid time of the second MTU,

[0074] If the size of the third data packet is larger than the first MTU, discarding the third data packet;

[0075] The first field is used to indicate the second MTU.

[0076] Here, the first field of the negotiation response message is used to indicate the second MTU. When the first field is set to empty or 0, and / or the valid time of the second MTU times out, the terminal no longer applies the second MTU to the received third data packet, but resumes comparing its size with the first MTU, discarding data packets whose size is larger than the first MTU, and retaining data packets whose size is less than or equal to the first MTU.

[0077] That is, when the first field is set to empty or 0, and / or the valid time of the second MTU times out, the terminal and the network side device do not set or cancel the reverse MTU size, and the MTU size set based on the first MTU is used for data packet transmission processing.

[0078] Of course, the terminal may also use the third data packet as the first data packet, restart the above steps, and negotiate a new second MTU.

[0079] Optionally, the first data packet and the third data packet belong to the same application, or belong to different applications, which is not limited in this embodiment.

[0080] Next, combine Figure 2 The application of the method of the embodiment of the present application is described as follows:

[0081] Step 201: The network server sends a data packet larger than a first MTU to a terminal.

[0082] That is, the network server receives a first data packet from a third-party server or the network server itself that is larger than the first MTU, and the network server sends the first data packet to the terminal.

[0083] Step 202: The terminal parses the data packet and sets the reverse MTU size.

[0084] That is, when the terminal receives the first data packet sent by the network server, it will parse the size of the first data packet, compare the size of the first data packet (the third MTU) with the first MTU, and if the third MTU exceeds the first MTU, set the third MTU as the reverse MTU size of the terminal.

[0085] Step 203: The terminal sends a negotiation message to the network server, carrying the first data packet and the third MTU.

[0086] That is, after the terminal sets the reverse MTU size in step 202, it will immediately establish a data connection with the network server, send a negotiation message, and send the first data packet and the third MTU to the network server.

[0087] Step 204: The network server responds to the negotiation message and parses the size and the first MTU of the first data packet.

[0088] That is, when the network server receives the first data packet sent by the terminal, the network server will parse out the size and the third MTU of the first data packet. At this time, if the network server can process the first data packet normally, the second MTU is determined by the size of the first data packet (the fourth MTU) and one of the third MTU, and it is set as the reverse MTU size of the network server, and a negotiation response message is sent to the terminal, such as data packet feedback signaling, indicating the second MTU. Here, in order to avoid setting the reverse MTU size too frequently, the largest third MTU or the size of the first data packet received from the terminal within the set time length t or the number of times n can be used as the reverse MTU size. If the network server cannot process the first data packet, the reverse MTU size is not set.

[0089] Step 205: The network server sends a negotiation response message to the terminal, indicating the second MTU.

[0090] That is, after setting the reverse MTU size, the network server will send a negotiation response message to the terminal, carrying the reverse MTU size recognized by the network server, that is, the second MTU.

[0091] Step 206: The terminal sets the MTU size and receives the data packet.

[0092] That is, when the terminal receives the negotiation response message sent by the network server, it will parse the second MTU and use the second MTU as the reverse MTU size of the terminal; if the field indicating the second MTU in the negotiation response message is empty or 0, the terminal does not set the reverse MTU size. The terminal receives the data packet from the network server according to the reverse MTU size and updates the reverse MTU size in real time.

[0093] However, when the application to which the first data packet belongs is disconnected or exits the application, the terminal and the network server set the reverse MTU size to empty or cancel the reverse MTU size. When the application is started again, the second MTU is renegotiated and the reverse MTU size is set.

[0094] It should also be known that, in this embodiment, the reverse MTU size newly set by the terminal is the receiving MTU size of the terminal, and the reverse MTU size newly set by the network side device is the sending MTU size of the network side device.

[0095] The first MTU, the second MTU, the third MTU, and the fourth MTU are actually the size values ​​of the MTU.

[0096] In summary, the method of the embodiment of the present application negotiates a second MTU for abnormal data packets between the terminal and the network side device, which can avoid the problem of only setting a first MTU, and when the first MTU is smaller than its own processing capacity, it cannot process the received data packets larger than the first MTU, thereby reducing the probability of packet loss. For data packets of the same application, it can prevent problems such as the application being unable to open halfway or the call being disconnected.

[0097] Moreover, the reverse MTU size temporarily set by the second MTU is based on the application setting. Different applications set different reverse MTU sizes. After the application exits, it is restored to the first MTU, which expands the flexibility of MTU application. The size of the data packet sent by the terminal or network side device depends on the processing capability of the other end, and is not limited by its own data packet processing capability, so that unnecessary data packet fragmentation can be reduced when sending data, thereby reducing packet loss and packet disorder problems.

[0098] like Figure 3 As shown, a data processing method in an embodiment of the present application is executed by a network side device, including:

[0099] Step 301: A negotiation message sent by a receiving terminal when a first data packet sent by the network side device is received and the size of the first data packet is greater than a first MTU;

[0100] Step 302: Send a negotiation response message according to the negotiation message; wherein the negotiation response message is used to indicate a second MTU, and the second MTU is greater than the first MTU;

[0101] Step 303: Send a second data packet to the terminal according to the second MTU; wherein the size of the second data packet is less than or equal to the second MTU.

[0102] In this way, according to the above steps 301-303, after the network side device sends the first data packet larger than the first MTU, the terminal can send a negotiation message to the network side device, and then the network side device sends a negotiation response message indicating the second MTU in response to the negotiation message. In this way, when sending the second data packet, the terminal can save the second data packet less than or equal to the second MTU to ensure the transmission of data packets larger than the first MTU between the network side device and the terminal.

[0103] Optionally, the negotiation message includes at least one of the following:

[0104] the first data packet;

[0105] A third MTU, where the third MTU is determined by the size of the first data packet determined by the terminal.

[0106] Optionally, the sending a negotiation response message according to the negotiation message includes:

[0107] In a case where the negotiation message includes the first data packet, obtaining a fourth MTU by parsing the first data packet;

[0108] The fourth MTU is used as the second MTU, and the negotiation response message is generated and sent.

[0109] That is, after receiving the first data packet sent by the terminal, the network side device determines the size of the first data packet, that is, the fourth MTU, through analysis, and uses the fourth MTU as the second MTU.

[0110] Optionally, the sending a negotiation response message according to the negotiation message includes:

[0111] In a case where the negotiation message includes the third MTU, the third MTU is used as the second MTU, and the negotiation response message is generated and sent.

[0112] That is to say, after the network side device receives the third MTU sent by the terminal, it directly uses the third MTU as the second MTU.

[0113] Optionally, the sending a negotiation response message according to the negotiation message includes:

[0114] In a case where the negotiation message includes the first data packet and the third MTU, obtaining a fourth MTU by parsing the first data packet;

[0115] Select one of the fourth MTU and the third MTU as the second MTU, and generate and send the negotiation response message.

[0116] That is, after receiving the first data packet sent by the terminal, the network side device determines the size of the first data packet, that is, the fourth MTU, by parsing. Since the network side device also receives the third MTU, the network side device selects one of the third MTU and the fourth MTU as the second MTU. For example, the minimum or maximum value of the third MTU and the fourth MTU is selected as the second MTU.

[0117] Optionally, the second data packet is transmitted within a valid time of the second MTU.

[0118] That is, the terminal will compare the size of the data packet received within the valid time with the second MTU, and save the data packet whose size is less than or equal to the second MTU.

[0119] Optionally, the method further comprises:

[0120] When the first field of the negotiation response message is set to be empty or 0, and / or when a third data packet needs to be transmitted outside the valid time of the second MTU, sending a third data packet to the terminal;

[0121] The size of the third data packet is larger than the first MTU.

[0122] Here, the first field is used to indicate the second MTU. The first field is set to empty or 0, and / or the validity period of the second MTU times out, which can be understood as the failure of the second MTU, that is, the terminal and the network side device do not set or cancel the reverse MTUsize. The third data packet is an abnormal data packet, that is, the network side device can send a data packet larger than the first MTU to the terminal in a specific scenario based on the first MTU. When the terminal receives the third data packet, it will resume comparing its size with the first MTU and retain data packets whose size is less than or equal to the first MTU.

[0123] Optionally, the third data packet and the first data packet originate from the same application.

[0124] It should be noted that this method is implemented in conjunction with the above-mentioned method executed by the terminal, and the implementation method of the above-mentioned method embodiment is applicable to this method and can achieve the same technical effect.

[0125] The data processing method provided in the embodiment of the present application can be executed by a data processing device. In the embodiment of the present application, the data processing device provided in the embodiment of the present application is described by taking the data processing method executed by the data processing device as an example.

[0126] like Figure 4 As shown, a data processing device according to an embodiment of the present application includes:

[0127] A first sending module 410 is configured to send a negotiation message to the network side device when a first data packet sent by the network side device is received and the size of the first data packet is greater than a first maximum transmission unit MTU;

[0129] The first processing module 430 is configured to save the second data packet when a second data packet sent by the network side device is received and the size of the second data packet is less than or equal to the second MTU.

[0130] After receiving a first data packet larger than the first MTU, the device sends a negotiation message to the network side device, and then receives a negotiation response message including a second MTU sent by the network side device based on the negotiation message. When receiving a second data packet sent by the network side device, the device saves the second data packet. That is, the terminal can save the second data packet sent by the network side device that is less than or equal to the second MTU based on the negotiated second MTU, thereby ensuring the transmission of data packets larger than the first MTU between the network side device and the terminal.

[0131] Optionally, the negotiation message includes at least one of the following:

[0132] the first data packet;

[0133] A third MTU, where the third MTU is determined by the size of the first data packet determined by the terminal.

[0134] Optionally, the second MTU is one of the third MTU and the fourth MTU;

[0135] The fourth MTU is determined by the size of the first data packet determined by the network side device.

[0136] Optionally, the second data packet is transmitted within a valid time of the second MTU.

[0137] Optionally, the device further comprises:

[0138] The second processing module is configured to, when the first field of the negotiation response message is set to be empty or 0 and / or, when a third data packet is received outside the valid time of the second MTU,

[0139] If the size of the third data packet is larger than the first MTU, discarding the third data packet;

[0140] The first field is used to indicate the second MTU.
