[0024] The data packet type to be parsed does not belong to the preset data packet type.

[0025] In one embodiment, the method further includes: outputting the target data information in a visual form.

[0026] According to a second aspect of the present disclosure, a data parsing apparatus is provided, comprising: an acquisition module, configured to acquire a data packet to be parsed;

[0027] The parsing module is used to parse the physical layer of the data packet to be parsed in order to determine the data packet format of the data packet to be parsed; if it is determined that the parsed data packet format is the target data packet format, then the MAC layer of the data packet to be parsed is parsed to obtain the MAC layer information included in the data to be parsed; based on the MAC layer information, the target data information included in the data packet to be parsed is determined.

[0028] In one embodiment, the MAC layer information includes at least the data packet type.

[0042] The technical solutions provided by the embodiments of this disclosure can include the following beneficial effects: After obtaining the data packet to be parsed, the physical layer of the data packet to be parsed is parsed to determine the data packet format. If the parsed data packet format is determined to be the target data packet format, the MAC layer of the data packet to be parsed is parsed to obtain the MAC layer information included in the data to be parsed, and then the target data information included in the data packet to be parsed is determined based on the MAC layer information. It can be seen that the technical solution provided by this disclosure, by parsing the physical layer and MAC layer of the data packet, eliminates the need for complete parsing of each layer of the data packet, thus shortening the data parsing time. Furthermore, the technical solution provided by this disclosure can directly obtain the target data information included in the data packet to be parsed based on the MAC layer information, eliminating the need for manual calculation of the MAC layer information and improving the parsing efficiency.

[0053] Figure 9 This is a block diagram illustrating a data parsing apparatus according to an exemplary embodiment. Detailed Implementation

[0054] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure.

[0055] In the accompanying drawings, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The described embodiments are some, but not all, of the embodiments of this disclosure. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting this disclosure. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without inventive effort are within the scope of protection of this disclosure. The embodiments of this disclosure will be described in detail below with reference to the accompanying drawings.

[0056] As described in the background section, due to the wide variety of data packets and the different data storage patterns of different types of data packets, it is difficult to achieve accurate data parsing and extraction. Related technologies typically parse each data packet completely, resulting in excessively long parsing times.

[0057] like Figure 1 As shown, Figure 1This is a flowchart illustrating a data parsing method in a related art, as shown in an exemplary embodiment. The specific parsing process is as follows: The physical layer of the data packet is parsed to determine whether the data packet format belongs to the target data packet format (e.g., IEEE 80211 format). If the data packet belongs to the target data packet format, the data link layer of the data packet is completely parsed to obtain Media Access Control Address (MAC) information and determine whether a network layer header is included. If a network layer header is included, the Internet Protocol (IP) and Address Resolution Protocol (ARP) information in the network layer of the data packet is completely parsed, and data validity is verified to determine whether a transport layer header is included. After determining that a transport layer header is included, the Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) information in the network layer is completely parsed, and data validity is verified. The data packet parsing ends.

[0058] It is evident that while related technologies can fully present all the information contained in a data packet during parsing, they cannot perform calculations on that information, thus failing to extract specific data. Specific data requires manual calculation based on the parsed information, resulting in extremely low parsing efficiency. Furthermore, because these technologies perform complete parsing of each layer of the data packet, the overall parsing time is excessively long.

[0059] Based on this, embodiments of this disclosure provide a data parsing method that eliminates the need to parse every layer of the data packet. By parsing the physical layer and the MAC layer in the data link layer, the parsing time is reduced. Furthermore, the target data information can be obtained based on the parsed MAC information without manual calculation, thus improving the parsing efficiency of the data packet.

[0060] Figure 2 This is a flowchart illustrating a data parsing method according to an exemplary embodiment, such as... Figure 2 As shown, it includes the following steps.

[0061] In step S11, the data packet to be parsed is obtained.

[0062] The data packets to be parsed differ depending on the parsing scenario.

[0063] For example, in a scenario where the parsing needs to obtain the activation or sleep data of a wireless device, the data packet to be parsed should be a data packet that includes at least the activation or sleep data of the wireless device.

[0064] For example, if the parsing scenario is one that needs to measure the current space-time transmission performance of a wireless device, the data packet to be parsed should include at least the frame length, transmission rate, retransmission time, number of retransmissions, and retransmission rate of the wireless device when transmitting data frames.

[0065] In step S12, the physical layer of the data packet to be parsed is parsed to determine the data packet format.

[0066] The data packet format to be parsed can be an empty data packet format, a wired data packet format, or other data packet formats.

[0067] Among them, the space-time data packet format represents wireless data packets transmitted wirelessly, while the wired data packet format represents data packets transmitted in a data cable.

[0068] In one implementation, the physical layer of the data packet to be parsed is parsed to obtain the header of the data packet to be parsed, and the data packet format of the data packet to be parsed is determined based on the header of the data packet to be parsed.

[0069] For example, if the header of the data packet to be parsed is an IEEE 80211 message, then the data packet format of the data packet to be parsed is determined to be empty data.

[0070] In step S13, if it is determined that the parsed data packet format is the target data packet format, then the MAC layer of the data packet to be parsed is parsed to obtain the MAC layer information included in the data to be parsed.

[0071] The MAC layer is a sublayer of the data link layer. In this embodiment of the disclosure, the MAC layer is mainly parsed when parsing the data link layer.

[0072] In one implementation, the target data packet format can be either an empty time data packet format or a wired data packet format.

[0073] In step S14, the target data information included in the data packet to be parsed is determined based on the MAC layer information.

[0074] The target data information differs depending on the parsing scenario. The target data information can be manually specified, and even within the same application scenario, the target data information can vary.

[0075] For example, if the application scenario is that the first device instructs the second device to enter a sleep state or an active state, then the target data information shall include at least one of the following: the planned activation time of the second device, the planned sleep time, the actual activation time, the actual sleep time, the actual activation time, the actual sleep time, etc.

[0076] In this embodiment, by parsing the physical layer and MAC layer of the data packet, it is not necessary to perform complete parsing of each layer of the data packet, thus shortening the data parsing time. Furthermore, the technical solution provided in this disclosure can obtain the target data information included in the data packet to be parsed based on the MAC layer information, eliminating the need for manual calculation of the MAC layer information and improving the parsing efficiency.

[0077] In some embodiments, the MAC layer information includes at least the packet type.

[0078] In one implementation, the data packet type is determined based on the frame type within the data packet.

[0079] For example, if the frame type of the data packet is a NullData frame, then the data packet type is NullData.

[0080] In other embodiments, the MAC layer information may also include the source address and the destination address.

[0081] Wherein, the source address is the address of the sender of the data packet to be parsed, and the destination address is the address of the receiver of the data packet to be parsed.

[0082] In one implementation, if the MAC information includes packet type, source address, and destination address, step S13 can be specifically implemented as steps S21-S23, such as... Figure 3 As shown:

[0083] In step S21, if the source address in the MAC information matches the preset source address and the destination address in the MAC information matches the preset destination address, then the data packet type of the data packet to be parsed is determined.

[0084] Specifically, by determining whether the source address matches the preset source address, it can be determined whether the sender of the data packet to be parsed is the sender of the preset source address; by determining whether the destination address matches the preset destination address, it can be determined whether the receiver of the data packet to be parsed is the receiver of the preset destination address, thereby determining whether the data packet to be parsed is a data packet capable of obtaining target data information.

[0085] In step S22, if the data packet type is a preset data packet type, then the key information of the data packet to be parsed is obtained.

[0086] Among them, the preset data packet type is determined based on the target data information that needs to be obtained.

[0087] For example, if the target data information to be obtained is the activation data or sleep data of a wireless device, since the frame type for sending activation data or sleep data in actual application scenarios is a NullData frame, the default data packet type is NullData.

[0088] The key information includes the data encapsulated in the data packet to be parsed.

[0089] For example, the data information encapsulated in the data packet to be parsed includes information such as the transmission time, retransmission information, frame length, and transmission rate of the message carried in the data packet to be parsed.

[0090] It should be understood that the key information obtained from the data packet to be parsed differs depending on the data packet type. In step S23, based on the key information, the target data information included in the data packet to be parsed is determined.

[0091] In this embodiment of the disclosure, since the same transmission frequency band includes data packets to be parsed and other data packets, it is necessary to determine whether the source address matches the preset source address and whether the destination address matches the preset destination address in order to determine whether the data packet currently being parsed is the specified data packet to be parsed, so as to accurately parse the target data information.

[0092] In another implementation, if the MAC layer information includes the data packet type, step S13 can be specifically implemented as steps S31-S32, such as... Figure 4 As shown:

[0093] In step S31, if the data packet type is a preset data packet type, then the key information of the data packet to be parsed is obtained.

[0094] The key information includes the data encapsulated in the data packet to be parsed.

[0095] In step S32, the target data information included in the data packet to be parsed is determined based on the key information.

[0096] In this embodiment, it is not necessary to determine whether the source address matches a preset source address or whether the destination address matches a preset destination address. That is, it is not necessary to determine whether the currently parsed data packet is the specified data packet to be parsed. The subsequent parsing process is executed directly, without concern for whether the desired target data information can be parsed. Of course, the parsing efficiency of this embodiment is lower than that of the previous embodiment.

[0097] In some embodiments, the key information includes at least the transmission type of the data packet to be parsed, which includes retransmission type and non-retransmission type.

[0098] In one implementation, there is a correspondence between the data packets to be parsed of different transmission types and the target data information.

[0099] For example, when the target data information to be obtained is the activation time or sleep time of a wireless device, if the transmission type of the data packet to be parsed is retransmission, the corresponding target data information is the actual activation time or actual sleep time; if the transmission type of the data packet to be parsed is non-retransmission, the corresponding target data information is the planned sleep time, actual sleep time, planned activation time, or actual activation time of the previous cycle.

[0100] In another implementation, there is a correspondence between different frame information of the data packets to be parsed of the same transmission type and the target data information. The frame information of the data packets to be parsed is used to indicate the function of the data frames included in the data packets to be parsed.

[0101] For example, when the target data information to be obtained is the activation time or sleep time of a wireless device.

[0102] When the transmission type of the data packets to be parsed is non-retransmission, if the frame information of the data packet indicates that the function of the data frame included in the data packet is to instruct the wireless device to enter a sleep state, then the corresponding target data information is the actual sleep entry time. If the frame information of the data packet indicates that the function of the data frame included in the data packet is to instruct the wireless device to enter an active state, then the corresponding target data information is the actual activation entry time.

[0103] In this embodiment of the disclosure, there is a correspondence between the data packets to be parsed of different transmission types and the target data information. Therefore, the correspondence between the data packets to be parsed and the target data information is determined based on the transmission type of the data packets to be parsed, which enables more accurate acquisition of the target data information.

[0104] In some embodiments, step S14 may be specifically implemented as steps S41-S43, such as... Figure 5 As shown:

[0105] In step S41, the transmission type of the data to be parsed is determined based on the key information.

[0106] In step S42, the target correspondence triggered by the transmission type of the data to be parsed is determined based on the transmission type of the data to be parsed.

[0107] In step S43, the target data information included in the data packet to be parsed is determined based on the target correspondence.

[0108] In this embodiment of the disclosure, the correspondence between the data packet to be parsed and the target data information is determined by the transmission type of the data packet, thereby obtaining the target data information more accurately.

[0109] In some embodiments, when the data packet to be parsed meets a preset rule, a new data packet to be parsed is obtained;

[0110] The preset rules include at least one of the following:

[0111] The data format of the data packet to be parsed does not belong to the target data packet format;

[0112] The source address of the data packet to be parsed does not match the preset source address, and / or the destination address does not match the preset destination address;

[0113] The data packet type to be parsed does not belong to the preset data packet type.

[0114] In other embodiments, after the target data information of the data packet to be parsed has been obtained, a new data packet to be parsed is also obtained. In some embodiments, after obtaining the target data information, the target data information is output in a visual form for a more intuitive understanding.

[0115] To more clearly illustrate the data parsing method proposed in the embodiments of this disclosure, the data parsing method proposed in the embodiments of this disclosure will be described in more detail below in the form of exemplary embodiments.

[0116] In one exemplary embodiment, taking the first device instructing the second device to enter an active or dormant state as an example, the target data information includes the planned activation time of the second device, or the planned dormant time, or the actual activation time, or the actual dormant time, or the actual activation time, or the actual dormant time, etc.

[0117] like Figure 6As shown, the first device sends a NullData PS=0 message (data packet type is NullData, frame information is 0, frame information is manually set or device default; different frame information is used to indicate different states for the second device; in this embodiment, frame information 0 indicates the second device is in an active state, and frame information 1 indicates the second device is in an active state) to notify the second device to enter the active state. The time when the NullData PS=0 message is sent is the planned time for the second device to enter the active state. However, due to certain factors (such as data packet loss), the second device may not receive the NullData PS=0 message, resulting in a NullData PS=0 message retransmission event. The time of the last retransmission of the NullData PS=0 message in the current cycle is the actual time the second device enters the active state. The first device then sends a NullData PS=1 message to notify the second device to enter a sleep state. The time when the NullData PS=1 message is sent is the planned time for the second device to enter the sleep state. However, NullData PS=1 messages may be retransmitted. Therefore, the time of the last retransmission of a NullData PS=1 message in the current cycle is the actual time the second device enters sleep mode. The planned activation time of the second device is determined based on the time difference between the planned activation time and the planned sleep time. The actual activation time of the second device is determined based on the time difference between the actual activation time and the actual sleep time. The planned sleep time of the second device is determined based on the time difference between the planned sleep time and the planned activation time. The actual sleep time of the second device is determined based on the time difference between the actual sleep time and the actual activation time.

[0118] At this point, the data packet to be parsed consists of a message sent by the first device when instructing the second device to enter an active or dormant state. For example... Figure 7 As shown, the physical layer of the data packet to be parsed is analyzed. When it is determined that the data packet format is IEEE 80211, the MAC layer of the data packet is analyzed to obtain the source address, destination address, and data packet type. When it is determined that the data packet format is not IEEE 80211, the parsing of the currently parsed data packet is abandoned, and a new data packet to be parsed is obtained.

[0119] When the source address of the data packet to be parsed matches the preset source address and the destination address matches the preset destination address, it is determined whether the data packet type of the data packet to be parsed is a data packet type that includes NullData frames. If the data packet type of the data packet to be parsed is a data packet type that includes NullData frames, then key information such as the current timestamp and transmission type of the data packet to be parsed is recorded. When the source address of the data packet to be parsed does not match the preset source address and / or the destination address does not match the preset destination address and / or the data packet type of the data packet to be parsed does not belong to the data packet type that includes NullData frames, the parsing of the currently parsed data packet is abandoned, and a new data packet to be parsed is obtained.

[0120] The triggering correspondence is determined based on key information. If the data packet to be parsed includes the first NullDataPS=0 data frame, the determined target data information is the planned activation time and actual activation time of the previous cycle. If the data packet to be parsed includes a non-first NullDataPS=0 data frame, the determined target data information is the actual activation time, and the parsing of the data packet to be parsed ends. If the data packet to be parsed includes the first NullDataPS=1 data frame, the determined target data information is the planned sleep time and actual sleep time of the previous cycle. If the data packet to be parsed includes a non-first NullDataPS=1 data frame, the determined target data information is the actual sleep time, the parsing of the data packet to be parsed ends, and a new data packet to be parsed is obtained.

[0121] In another exemplary embodiment, taking a parsing scenario where it is necessary to measure the performance of a wireless device in transmitting data packets under the current space-time conditions as an example, the target data information includes: frame length: the frame length of the data packet; transmission rate: the transmission rate used by the data packet; timestamp: the transmission time of the data packet; sequence number: the sequence number of the data packet; session information: the transmission session identifier; retransmission calculation timing: retransmission calculation is triggered when two consecutive data packets with the same session identifier and the same sequence number are used; retransmission time: the current retransmission time of data packets with the same sequence number minus the transmission time of the first frame; number of retransmissions: the number of data packets with the same sequence number minus 1; retransmission rate: the transmission rate used by data packets with the same sequence number; retransmission space-time occupancy: the sum of the frame lengths of data packets with the same sequence number; total data length: the sum of the frame lengths of data packets with the same session identifier.

[0122] When parsing a data packet, the physical layer of the packet is parsed first. If the packet format is determined to be IEEE 80211, the MAC layer is parsed to obtain the source address, destination address, and packet type. If the packet format is determined to be different from IEEE 80211, the parsing of the currently parsed packet is abandoned, and a new packet is obtained.

[0123] When the source address of the data packet to be parsed matches the preset source address and the destination address matches the preset destination address, it is determined whether the data packet type of the data packet to be parsed is a data packet type that includes QoS Data frames. If the data packet type of the data packet to be parsed is a data packet type that includes QoS Data frames, then the current timestamp, session identifier, sequence number, transmission rate, and other key information of the data packet to be parsed are recorded. When the source address of the data packet to be parsed does not match the preset source address and / or the destination address does not match the preset destination address and / or the data packet type of the data packet to be parsed does not belong to the data packet type that includes QoS Data frames, the parsing of the currently parsed data packet is abandoned, and a new data packet to be parsed is obtained.

[0124] The key information determines the correspondence between the triggered and target data information. If the key information determines that the data packet to be parsed is a retransmission data packet, the determined target data information is the frame length of the data packet, transmission rate, timestamp, session identifier, current session identifier, retransmission time / retransmission rate / retransmission count, and retransmission time occupation of the current sequence number, and the parsing of the data packet to be parsed ends. If the key information determines that the data packet to be parsed is a non-retransmission data packet, the determined target data information is the frame length of the data packet and the total data length of the current session identifier, and the parsing of the data packet to be parsed ends.

[0125] As can be seen from the above exemplary embodiments, the data parsing method provided in this disclosure shortens the data parsing time by parsing the physical layer and MAC layer of the data packet, eliminating the need for complete parsing of each layer. Furthermore, the technical solution provided in this disclosure can directly obtain the target data information included in the data packet to be parsed based on the MAC layer information, without requiring manual calculation of the MAC layer information, thus improving the parsing efficiency.

[0126] Experiments have shown that the data parsing method provided in this disclosure is 300% more efficient than the data parsing methods in related technologies. Of course, the processor performance of different devices used to execute this data parsing method is different, and the parsing efficiency of the data parsing method provided in this disclosure will also vary.

[0127] Based on the same concept, embodiments of this disclosure also provide a data parsing apparatus.

[0128] It is understood that the data parsing apparatus provided in this disclosure includes hardware structures and / or software modules corresponding to each function in order to achieve the above-mentioned functions. In conjunction with the units and algorithm steps of the various examples disclosed in this disclosure, this disclosure can be implemented in hardware or a combination of hardware and computer software. Whether a function is executed by hardware or by computer software driving hardware depends on the specific application and design constraints of the technical solution. Those skilled in the art can use different methods to implement the described functions for each specific application, but such implementation should not be considered beyond the scope of the technical solutions of this disclosure.
