Description

Technical Field

[0001] The present application relates to the field of data communications, and in particular to a message generation and verification method, device, system, equipment, cluster, medium and product. Background Art

[0002] In order to ensure the working efficiency of the host, the slices are often unloaded to the network card for processing, and the network card calculates the checksum of the sliced ​​slices. Once there is an abnormality inside the network card, the corresponding abnormal message cannot be identified by the checksum. For example, if the data is garbled when the host sends data to the network card; or, data garbled or packet sticking occurs during slicing, the corresponding checksum will still be calculated based on the erroneous data when filling the checksum. At this time, the receiving end cannot rely on the checksum mechanism of the network protocol specification to detect the erroneous message, and the erroneous message will still be sent to the specific application. Summary of the invention

[0055] Figure 4 It is a structural schematic diagram of a computing device provided by this application. DETAILED DESCRIPTION

[0056] The embodiments of the present invention are described below in conjunction with the accompanying drawings in the embodiments of the present invention. The terms used in the implementation mode of the present invention are only used to explain the specific embodiments of the present invention, and are not intended to limit the present invention.

[0057] See also Figure 1 , Figure 1 This is a flow chart of a message verification method provided by this application. Figure 1 As shown, the message verification method of the present application includes:

[0058] S101: A sending device obtains first data to be transmitted through a host.

[0059] The first data to be transmitted includes a first message header and a first payload. The first message header may include a layer 2 (L2) message header, a layer 3 (L3) message header, a layer 4 (L4) message header, a tunnel message header, etc.

[0060] S102: The sending device processes the first data to be transmitted through the host to obtain the second data to be transmitted.

[0061] like Figure 2As shown, the host estimates the length of each segment in the first load based on the maximum segment size, inserts a check message header in each segment, sets the check message header in each segment to the first value to obtain multiple inserted segments, estimates the estimated message header of each segment based on the first message header, calculates each checksum based on the estimated message header of each segment and the corresponding inserted segment, and fills each checksum into the corresponding check message header to obtain the second data to be transmitted. Among them, the maximum segment size (Maximum Segment Size, MSS) refers to the size of the maximum data segment that can be sent in the Transmission Control Protocol (TCP) connection. The user can set the size of the maximum segment size as needed, for example, it can be 1460 bytes, etc. The size of the check message header can be set according to user needs, for example, 3 bytes, 4 bytes or 5 bytes, etc. The first value can be that all bits are 0, all bits are 1, or some bits are 0, some bits are 1, etc. The length of the estimated message header of each segment is the same, and the contents of the estimated message headers of different segments may be different, but they can all be estimated based on the first message header.

[0062] For example, the host determines the first segment from the first load according to the maximum segment size, wherein the first segment includes a first check message header. Then, the host sets the first check message header in the first segment to a first value to obtain a first insertion segment, estimates the first estimated message header according to the first message header, calculates the first checksum based on the first estimated message header and the first insertion segment, and fills the first checksum into the first inspection message header. The host determines the second segment from the first load according to the maximum segment size, wherein the second segment includes a second check message header. Then, the second check message header in the second segment is set to a first value to obtain a second insertion segment, estimates the second estimated message header according to the first message header, calculates the second checksum based on the second estimated message header and the second insertion segment, and fills the second checksum into the second inspection message header, and so on, until the last segment is processed and the second data to be transmitted is obtained. The above processing of each segment can be parallel or serial, which is not specifically limited here.

[0063] In order to quickly determine which message has failed when a message fails, data can be carried in each segment by increasing or decreasing. For example, data 1 can be carried in the first segment, data 2 can be carried in the second segment, and so on, until the last segment. Alternatively, data 100 can be carried in the first segment, data 98 ​​can be carried in the second segment, and so on, until the last segment. Of course, data 50 can be carried in the first segment, data 53 can be carried in the second segment, and so on, until the last segment.

[0064] In addition to carrying the checksum, the first check message header can also be used to carry one or more of the segment number, the maximum segment size, and the starting increment number. Among them, the segment number is used to indicate the position of the segment in the first data to be transmitted, the maximum segment size is used to indicate the size of the segment, and the starting increment number is used to indicate the data carried in the first segment. The above-mentioned carrying contents are only used as specific examples. In actual applications, the first check message header can also include other contents, which are not specifically limited here.

[0065] S103: The host of the sending device sends the second data to be transmitted to the network card of the sending device. Correspondingly, the network card of the sending device receives the second data to be transmitted sent by the host of the sending device.

[0066] S104: The network card of the sending device processes the second data to be transmitted to obtain multiple data packets.

[0067] The network card of the sending device divides the second data to be transmitted according to the maximum segment size to obtain multiple fragments. Then, a fragment header is added to each fragment to obtain each data message, and each data message is sent. For example, the second data to be transmitted is divided by the network card based on the maximum segment size to obtain a first fragment containing a first check message header, and a first fragment header is added to the first fragment to obtain a first data message, and the first data message is sent. Then, the second data to be transmitted is divided by the network card based on the maximum segment size to obtain a second fragment containing a second check message header, and a second fragment header is added to the second fragment to obtain a second data message, and the second data message is sent, and so on, until the last fragment is processed.

[0068] Since the host of the sending device estimates the segments according to the maximum segment size, and when segmenting the first data to be transmitted, it is also segmented according to the maximum segment size, so the length of the first segment is the same as the length of the first segment, the length of the second segment is the same as the length of the second segment, and so on, the length of the last segment is the same as the length of the last segment. Similarly, the host of the sending device estimates each estimated message header according to the first message header, so the first estimated message header and the first segment message header are exactly the same, the second estimated message header and the second segment message header are exactly the same, and so on, the last estimated message header and the last segment message header are also exactly the same.

[0069] It is understandable that the network card of the sending device can also calculate multiple fragment checksums based on multiple fragment headers and multiple fragments, and carry the fragment checksums in the layer 4 header. In this case, each fragment can have two checksums, one is the calculated checksum, and the other is the fragment checksum.

[0070] S105: The network card of the sending device sends multiple data messages to the receiving device. Correspondingly, the receiving device receives the multiple data messages sent by the network card of the sending device.

[0071] Each data message in the plurality of data messages includes a fragment message header and a fragment, each fragment includes a check message header, and each first check message header includes a checksum. For example, the first data message includes a first fragment message header and a first fragment, the first fragment includes a first check message header, the first check message header includes a first checksum, the second data message includes a second fragment message header and a second fragment, the second fragment includes a second check message header, the second check message header includes a second checksum, and so on, until the last data message.

[0072] S106: The receiving device verifies the multiple data messages.

[0073] The receiving device sets the check message header in each fragment to a first value, obtains multiple value-set fragments, and calculates multiple calculated checksums based on each fragment message header and the corresponding value-set fragment. The multiple calculated checksums are compared with the corresponding checksums respectively. When each checksum is the same as the corresponding calculated checksum, it is determined that each data message is correct. If a checksum is different from the corresponding calculated checksum, it means that an error has occurred in the data message corresponding to the checksum. For example, the first check message header in the first fragment is set to the first value to obtain the first set value fragment, and the first calculated checksum is calculated based on the first fragment message header and the first set value fragment. The first checksum is compared with the first calculated checksum. When the first checksum is the same as the first calculated checksum, it is determined that the first data message is correct; then, the second check message header in the second fragment is set to the first value to obtain the second set value fragment, and the second calculated checksum is calculated based on the second fragment message header and the second set value fragment. The second checksum is compared with the second calculated checksum. When the second checksum is the same as the second calculated checksum, it is determined that the second data message is correct, and so on.

[0074] S107: The receiving device processes the multiple data messages to obtain multiple fragments, and splices the multiple fragments to obtain first data to be transmitted.

[0075] The receiving device deletes each check message header in each value-setting slice to obtain each segment, and splices multiple segments to obtain the first data to be transmitted. For example, the first check message header in the first value-setting slice is deleted to obtain the first segment; the second check message header in the second value-setting slice is deleted to obtain the second segment, and so on, until the last check message header in the last value-setting slice is deleted to obtain the last segment, and then, the multiple segments are spliced ​​in sequence to obtain the first data to be transmitted.

[0076] In the above scheme, the host calculates the checksum in advance before sending the data to be transmitted to the network card. Therefore, when an abnormality exists inside the network card, the corresponding abnormal message can be identified by the checksum.

[0077] See also Figure 3 , Figure 3 This is a schematic diagram of the structure of a message verification system provided by this application. Figure 3 As shown, the message verification system of the present application includes a sending device 110 and a receiving device 120 .

[0078] The sending device 110 includes a host 111 and a network card 112 .

[0079] The host 111 is used to obtain first data to be transmitted, wherein the first data to be transmitted includes a first message header and a first payload;

[0080] The host 111 is used to determine a first segment from the first payload according to a maximum segment size, wherein the first segment includes a first inspection message header;

[0081] The host 111 is used to set the first check message header in the first segment to a first value to obtain a first insertion segment, estimate the first estimated message header according to the first message header, calculate a first checksum based on the first estimated message header and the first insertion segment, fill the first checksum into the first check message header, obtain second data to be transmitted, and send the second data to be transmitted to the network card;

[0082] The network card 112 is used to divide the second data to be transmitted based on the maximum segment size to obtain a first fragment including a first check message header, and add a first fragment message header to the first fragment to obtain a first data message, and send the first data message, wherein the value of the first fragment message header is the same as the value of the first estimated message header.

[0083] Here, the sending device may execute as follows Figure 1 The steps performed by the sending device in the message verification method shown in the figure are as follows. Figure 1 and related descriptions.

[0084] The receiving device 120 includes: a receiving module 121 , a setting module 122 , a calculating module 123 and a comparing module 124 .

[0085] The receiving module 121 is used to receive a first data message, wherein the first data message includes a first fragment message header and a first fragment, the first fragment includes a first check message header, and the first check message header includes a first checksum;

[0086] The setting module 122 is used to set the first check message header in the first fragment to a first value to obtain a first set value fragment;

[0087] The calculation module 123 is used to calculate a first calculation checksum based on the first fragment message header and the first value-setting fragment;

[0088] The comparison module 124 is used to compare the first checksum with the first calculated checksum, and determine that the first data message is correct when the first checksum is the same as the first calculated checksum.
