[0070] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0071] It should be noted that, in this article, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0072] Figure 1 This is a schematic diagram of an application scenario provided by an embodiment of the present application. Figure 1 , including a terminal device 101, a relay device 102 and a server 103. The terminal device 101 can be a host, a mobile phone, a tablet computer, etc. The relay device 102 can be a router. During data transmission, the terminal device 101 can send a data packet to the relay device, and the relay device 102 processes the data packet and sends it to the server 103 through the core network. The server 103 can send a data packet to the relay device through the core network, and the relay device 102 processes the data packet and sends it to the terminal device 101.

[0073] In the related art, data can be processed in the following manner: a relay device receives a transmitted data packet and processes the data packet. According to the processing result, the data packet is sent to a terminal device or a core network. In the above process, since each received data packet is processed, the relay device processes data at a relatively slow speed.

[0074] In an embodiment of the present application, the relay device can merge multiple data packets to be processed. According to the working mode of the relay device, the merged data packets are processed accordingly. In the above process, multiple data packets can be processed at one time, rather than processing each data packet received, thereby improving the speed of data processing by the relay device.

[0075] Figure 2 A flowchart of a data processing method provided in an embodiment of the present application. Figure 2, the method may include:

[0076] S201: Obtain the working mode of the relay device.

[0077] The execution subject of the embodiment of the present application may be a relay device, or a chip, chip module or data processing device set in the relay device. The data processing device may be implemented by software, or by a combination of software and hardware. The relay device may be a router.

[0078] The working mode includes transparent mode and routing mode. You can get the working mode of the router according to the network configuration.

[0079] S202: Acquire a plurality of first data packets to be processed according to the working mode.

[0080] Multiple first data packets to be processed can be obtained in the following manner: if the working mode is a transparent transmission mode, multiple first data packets are obtained in the cache area; if the working mode is a routing mode, multiple first data packets are obtained in a sub-cache area in the cache area, and the cache area includes multiple sub-cache areas.

[0081] The data packets can be received by using a USB driver / WIFI driver or a modem, and stored in the corresponding buffer area. The buffer area can be allocated and set in advance in the router according to the protocol stack of the router (Transmission Control Protocol / Internet Protocol, TCPIP). Multiple transmission protocols are stored in the protocol stack.

[0082] A sub-buffer can store a fixed number of data packets. When the number of data packets stored in a sub-buffer reaches the fixed number, if new data packets are to be stored, the new data packets are stored in a new sub-buffer.

[0083] For example, a sub-buffer can store 100 data packets. When receiving data packets, the 100 data packets can be stored in the same sub-buffer. When the 101st data packet is received, the data is stored in a new sub-buffer.

[0084] Next, combine Figure 3 , a method for storing data packets in a buffer area is described. Figure 3 This is a schematic diagram of the cache area structure provided in the embodiment of this application. Figure 3, including a buffer area 301. The buffer area 301 is set in the router. The buffer area includes a plurality of sub-buffers, namely, sub-buffer 1, sub-buffer 2 and sub-buffer 3. Each sub-buffer can store 20 data packets. After receiving 45 first data packets to be processed using the USB driver, the first 20 first data packets are stored in sub-buffer 1, the 21st to 40th first data packets are stored in sub-buffer 2, and the 41st to 45th first data packets are stored in sub-buffer 3.

[0085] If the working mode of the router is transparent transmission mode, when obtaining the 45 data packets, the router directly obtains the 35 first data packets in the buffer area 301. If the working mode of the router is routing mode, multiple first data packets are obtained in the sub-buffer area in the buffer area 301.

[0086] S203: Combine the multiple first data packets according to the address information of the multiple first data packets to obtain at least one second data packet.

[0087] The address information may include source address, source port, destination address, destination port and transport protocol.

[0088] The source address is the Internet Protocol (IP) address of the terminal device that sends the data packet. The destination address is the IP address of the terminal device that receives the data packet.

[0089] The source port is the port used by the terminal device to send data packets. The destination port is the port used by the terminal device to receive data packets.

[0090] The transmission protocol can ensure the security and reliability of data transmission. For example, the transmission protocol can be any protocol in the Transmission Control Protocol / Internet Protocol (TCP / IP) family.

[0091] For example, the first data packet may be specifically as shown in Table 1:

[0092] Table 1

[0093]

[0094]

[0095] The second data packet includes at least one first data packet.

[0096] The second data packet can be obtained in the following manner: grouping multiple first data packets according to their address information to obtain at least one data packet group, wherein the address information of the first data packets in one data packet group is the same; and merging the address information in at least one data packet group to obtain at least one second data packet.

[0097] For example, according to Table 1, it is determined that the address information of the first data packet 1 and the first data packet 3 are the same, and the address information of the first data packet 2 and the first data packet 4 are the same. The data packets with the same address information are merged to obtain the second data packet, which can be specifically shown in Table 2:

[0098] Table 2

[0099]

[0100] The obtained at least one second data packet is sent to the protocol stack.

[0101] S204. Process at least one second data packet according to the working mode.

[0102] The second data packet can be processed in the following manner: if the working mode is the transparent transmission mode, the transmission protocol of the second data packet is obtained, and the second data packet is processed according to the transmission protocol; if the working mode is the routing mode, the second data packet is routed preprocessed and the second data packet is forwarded.

[0103] For example, the router receives multiple second data packets, which may be specifically shown in Table 3:

[0104] Table 3

[0105]

[0106] If the router is in transparent transmission mode, the transmission protocols of Pkt0, Pkt1 and Pkt2 are obtained, which are DHCP, ARP and NDP respectively. The protocol stack of the router processes Pkt0, Pkt1 and Pkt2 respectively according to the transmission protocol. If the router is in routing mode, the protocol stack of the router performs routing preprocessing on Pkt0, Pkt1 and Pkt2 and forwards the second data packet.

[0107] The data processing method provided in the embodiment of the present application obtains the working mode of the relay device; obtains multiple first data packets to be processed according to the working mode; merges and processes the multiple first data packets according to the address information of the multiple first data packets to obtain at least one second data packet; and processes at least one second data packet according to the working mode. In the above process, multiple data packets can be processed at one time, rather than processing each data packet received, thereby improving the speed of the relay device in processing data.

[0108] Figure 4 A flowchart of another data processing method provided in an embodiment of the present application. Figure 4 , the method may include:

[0109] S401: Obtain the working mode of the relay device.

[0110] If the working mode is the transparent transmission mode, execute S402-S405.

[0111] If the working mode is the relay mode, execute S406-S410.

[0112] It should be noted that the execution process of S401 refers to S201 and will not be repeated here.

[0113] S402: Acquire multiple first data packets in a buffer area.

[0114] S403: Combine the multiple first data packets according to the address information of the multiple first data packets to obtain at least one second data packet.

[0115] When merging a plurality of first data packets, all first data packets in the buffer area with the same address information are merged to obtain at least one second data packet.

[0116] S404: Obtain a transmission protocol of the second data packet.

[0117] The transmission protocol of the second data packet may be acquired according to the address information of the second data packet.

[0118] For example, the second data packet may be specifically as shown in Table 4:

[0119] Table 4

[0120]

[0121] According to Table 4, it can be determined that the transmission protocol of the second data packet Pkt0 is DHCP.

[0122] S403: Process the second data packet according to the transmission protocol.

[0123] For any second data packet, the second data packet can be processed in the following manner: if the transmission protocol is a local area network protocol, the second data packet is stored in the protocol stack; if the transmission protocol is not a local area network protocol, the second data packet is forwarded according to the destination address of the second data packet.

[0124] LAN protocols may include Dynamic Host Configuration Protocol (DHCP), Address Resolution Protocol (ARP), and Neighbor Discovery Protocols (NDP).

[0125] The second data packet stored in the protocol stack can be processed in the following manner: if the data transmission mode is uplink transmission, determine whether the destination address is a preset address; if so, process the second data packet according to the transmission protocol of the second data packet; if not, forward the second data packet according to the destination address of the second data packet.

[0126] If the data transmission mode is downlink transmission, the second data packet is processed according to the transmission protocol of the second data packet.

[0127] Uplink transmission refers to the transmission of data from the terminal device to the core network. Downlink transmission refers to the transmission of data from the core network to the terminal device.

[0128] The default address can be 10.0.25.240.

[0129] For example, the second data packet may be specifically as shown in Table 4 above. Assume that the router receives the second data packet sent by the terminal device and transmits the second data packet to the core network. According to Table 4, it is determined that the transmission protocol of the second data packet is the local area network protocol DHCP, and the destination address is the preset address 10.0.25.240. The second data packet is stored in the protocol stack, and the configuration information is sent to the terminal device according to the protocol DHCP.

[0130] The destination address and destination port of the second data packet can be obtained through the address information of the second data packet. The second data packet is sent to the corresponding destination address, and the receiving end (eg, terminal device) receives the second data packet using the destination port.

[0131] If the data transmission mode is uplink transmission, the second data packet is forwarded through the wide area network (WAN) port of the relay device. If the data transmission mode is downlink transmission, the second data packet is forwarded through the local area network (LAN) port of the relay device.

[0132] S406: Acquire multiple first data packets in the sub-buffer area.

[0133] S407: Combine the multiple first data packets according to the address information of the multiple first data packets to obtain at least one second data packet.

[0134] S408: Obtain the data type of the second data packet.

[0135] The data types include: from public network to private network, and from private network to public network.

[0136] The data type of the second data packet may be determined in the following manner: determining the source address and the destination address of the second data packet according to the address information of the second data packet, and determining the data type according to the source address and the destination address.

[0137] S409: Perform routing preprocessing on the second data packet according to the data type.

[0138] The routing preprocessing includes at least one of the following: protocol stack IP header parsing, firewall filtering, searching the Network Address Translation (NAT) table, searching the routing table, and searching the ARP table.

[0139] The second data packet can be routed preprocessed in the following manner: if the data type is from a public network to a private network, each first data packet in the second data packet is routed preprocessed; if the data type is from a private network to a public network, the first first data in the second data packet is routed preprocessed.

[0140] When the data type is from a public network to a private network, each first data packet in the second data packet needs to be NAT converted and filled with an Ethernet frame header.

[0141] For example, when the working mode of the router is the routing mode, the received second data packet may be specifically as shown in Table 5:

[0142] Table 5

[0143]

[0144] According to Table 5, it is determined that the source address of the second data packet Pkt1 belongs to the public network address, and it is determined that the destination address of the second data packet Pkt1 belongs to the private network address. According to the source address and destination address of the second data packet Pkt0, it is determined that the data type of the second data packet Pkt1 is from the public network to the private network. When performing route preprocessing on the second data packet Pkt0, route preprocessing is performed on each first data packet in the second data packet.

[0145] According to Table 5, it is determined that the source address of the second data packet Pkt0 belongs to the private network address, and it is determined that the destination address of the second data packet Pkt0 belongs to the public network address. According to the source address and the destination address of the second data packet Pkt0, it is determined that the data type of the second data packet Pkt0 is from the private network to the public network. When performing route preprocessing on the second data packet Pkt0, route preprocessing is performed on the first first data in the second data packet.

[0146] S410: forward the second data packet.

[0147] If the data transmission mode is uplink transmission, the second data packet is forwarded through the WAN port of the relay device. If the data transmission mode is downlink transmission, the second data packet is forwarded through the LAN port of the relay device.

[0148] The method for processing the second data packet provided in the embodiment of the present application selects a corresponding method to process and forward the second data packet according to the working mode. If the working mode is the transparent transmission mode, the transmission protocol of the second data packet is obtained, and the second data packet is processed according to the transmission protocol. If the working mode is the routing mode, the second data packet is routed preprocessed and the second data packet is forwarded. In the above process, multiple data packets can be processed at one time, instead of processing each data packet as it is received, thereby improving the speed at which the relay device processes data.

[0149] Based on any of the above embodiments, Figure 5A-Figure 5B , the process of data processing by relay equipment in different working modes is illustrated with examples.

[0150] Figure 5A A schematic diagram of a data processing process provided by an embodiment of the present application. Figure 5A , including a terminal device 501, a relay device 502 and a server 503. The terminal device 501 can be a mobile phone, a computer, etc. The relay device 502 can be a router, and a cache area and a protocol stack are set in the relay device 502. The cache area includes multiple sub-buffers. Data can be transmitted between the terminal device 501 and the server 503 through the core network. It is assumed that the working mode of the relay device 502 is the transparent transmission mode. There are two cases:

[0151] Case 1: The data transmission mode is uplink transmission.

[0152] The relay device 502 receives multiple first data packets to be processed sent by the terminal device 501 using a USB driver, and stores them in a buffer area pre-allocated by the protocol stack, and each sub-buffer area in the buffer area stores a fixed number of first data packets. All first data packets are obtained in the buffer area, and multiple first data packets are merged and processed according to the address information of the multiple first data packets to obtain at least one second data packet. The at least one second data packet is sent to the protocol stack of the relay device 502. The protocol stack determines the transmission protocol of the second data packet according to the address information of the second data packet. The second data packet whose transmission protocol is the local area network protocol is stored in the protocol stack. The second data packet whose transmission protocol is not the local area network protocol is forwarded to the server 503 through the WAN port of the relay device 502. For the second data packet in the protocol stack, it is determined whether the destination address is 10.0.25.240. If so, the second data packet is processed according to the transmission protocol of the second data packet. If not, the second data packet is forwarded to the server 503 through the WAN port of the relay device 502.

[0153] Case 2: The data transmission mode is downlink transmission.

[0154] The relay device 502 uses a modem to receive multiple first data packets to be processed sent by the server 503, and stores them in a buffer area pre-allocated by the protocol stack. Each sub-buffer in the buffer area stores a fixed number of first data packets. Multiple first data packets are obtained in the sub-buffer area, and multiple first data packets are merged and processed according to the address information of the multiple first data packets to obtain at least one second data packet. The at least one second data packet is sent to the protocol stack of the relay device 502. The protocol stack forwards the second data packet to the terminal device 501 through the LAN port of the relay device 502 according to the address information of the second data packet.

[0155] Figure 5B This is another data processing process diagram provided by the embodiment of the present application. Figure 5B , including a terminal device 501, a relay device 502 and a server 503. The terminal device 501 can be a mobile phone, a computer, etc. The relay device 502 can be a router, and a cache area and a protocol stack are set in the relay device 502. The cache area includes multiple sub-buffers. Data can be transmitted between the terminal device 501 and the server 503 through the core network. It is assumed that the working mode of the relay device 502 is the routing mode. There are two cases:

[0156] Case 1: The data transmission mode is uplink transmission.

[0157] The relay device 502 receives multiple first data packets to be processed sent by the terminal device 501 using a USB driver, and each sub-buffer in the buffer area stores a fixed number of first data packets. Multiple first data packets are obtained in the sub-buffer area, and multiple first data packets are merged and processed according to the address information of the multiple first data packets to obtain at least one second data packet. The at least one second data packet is sent to the protocol stack of the relay device 502. The protocol stack of the relay device 502 determines the source address and destination address of the second data packet according to the address information of the second data packet. The data type is determined according to the source address and the destination address. If the data type of the second data packet is from a shared network to a private network, each first data packet in the second data packet is routed preprocessed, NAT converted and filled with an Ethernet frame header. If the data type of the second data packet is from a private network to a shared network, the first first data in the second data packet is routed preprocessed. Among them, the route preprocessing includes at least one of the following: protocol stack IP header parsing, firewall filtering, NAT table search, routing table search, and ARP table search. After the processing is completed, the second data packet is forwarded to the server 503 through the WAN port of the relay device.

[0158] Case 2: The data transmission mode is downlink transmission.
