In order to better understand the technical solutions in the embodiments of the present application, the following descriptions will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present application, but not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the embodiments of the present application shall fall within the scope of protection of the embodiments of the present application.
The terminology used in the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the present application. As used in this application and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used herein refers to and encompasses any or all possible combinations of one or more of the associated listed items.
It should be understood that although the terms first, second, third, etc. may be used herein to describe various information, these information should not be limited by these terms. For example, a first message may also be referred to as a second message, and similarly, a second message may also be referred to as a first message, without departing from the scope of the present application. The word "if" as used herein may be interpreted as "at … …" or "at … …" or "responsive to a determination", depending on the context.
A first aspect of the embodiments of the present application provides a method for message communication, so as to solve the foregoing problem.
As shown in fig. 1, the message communication method provided in the embodiment of the present application includes:
s101: and receiving a plurality of message frames included in the message, and respectively checking each message frame to judge whether the message frame is an abnormal message frame or not.
In the embodiment of the application, whether the message frame is abnormal or not can be judged by detecting the frame head, the frame tail and the data volume contained in the message frame. It should be understood that, in this application, a packet frame is a Data frame (Data frame) that includes three parts, namely, a frame header, a Data portion, and a frame tail. Wherein the frame header and frame trailer may contain some necessary control information such as synchronization information, address information, error control information, etc.; the data portion includes message data included in the message frame. The specific structure of the message frame may refer to the related art, and will not be described herein.
S102: if the message frame is an abnormal message frame, the message frame is processed according to the abnormal type of the message frame, and when the processed message frame is obtained, the processed message frame is stored by a message storage unit.
When the message frame is found to be abnormal, the embodiment of the application can process the message frame according to the abnormal type of the message frame. For example, the message frame may be subjected to corresponding repair processing according to the anomaly type of the message frame, so that the message frame may be normally processed in a subsequent operation, and an anomaly identifier may be further added to the message frame to label the anomaly type of the message frame. The message storage unit and the following address storage unit may be a storage device such as a random access memory (Random Access Memory, RAM), a floppy disk, a hard disk, or a magneto-optical disk, or other suitable storage devices, which are all within the scope of the embodiments of the present application.
S103: and if the message frame is a normal message frame, storing the message frame through a message storage unit.
S104: writing the storage address of the processed message frame with the included abnormal identifier meeting the filtering rule into an address set in an address storage unit according to the abnormal identifier included in the processed message frame, and writing the storage address of the message frame determined to be a normal message frame into the address set, wherein the abnormal identifier is used for indicating the abnormal type of the message frame.
The filtering rules may indicate which memory addresses of the message frames corresponding to the anomaly identifications are written to the address set within the address memory location. When the storage address is written into the address set of the address storage unit, the message frame corresponding to the address is sent to the lower data receiving end, so that the filtering rule can be set to set which processed message frames corresponding to abnormal types can be sent to the lower data receiving end, and the lost message data is reduced; and setting which processed message frames corresponding to the abnormal types can be discarded, so that the efficiency of message transmission is improved. The filtering rules in the embodiment of the application can be set according to the requirements of the user, so that the requirements of the user can be better met, and the user experience is improved.
S105: after receiving the data acquisition request for the message, sending a message frame with a corresponding storage address in an address set to a data receiving end according to the data acquisition request.
The data acquisition request may indicate a data receiving end that receives the above-mentioned message. After receiving the data acquisition request, the address storage unit may read the storage address written in the address set in step S104, and according to the storage address, read the corresponding message frame from the message storage unit. And then the message frame with the corresponding storage address in the address set can be sent to the data receiving end. In this embodiment of the present application, the storage address of the message frame may include information such as a start address, an end address, and a data length stored in the message storage unit by the message frame, so that the stored message frame can be read from the message storage unit according to the storage address.
In the embodiment of the application, after detecting the message frames in the message and finding the abnormal message frames, the message frames are processed according to the abnormal types of the message frames, so that the processed message frames which can be read normally can be obtained, and therefore all abnormal message frames are not required to be discarded, and then the storage addresses of the message frames in the processed message frames can be determined to be written into the address set in the address storage unit according to the filtering rule, so that after receiving a data acquisition request for the message, the message frames can be sent to the data receiving end, the data loss in heat preservation transmission is reduced, and the large loss caused to a user is avoided.
It should be understood that the message communication method provided in the embodiment of the present application may be applied to communication devices such as switches and routers, and electronic terminals such as mobile phones and computers that may perform communication, and other external communication modules, which are all within the protection scope of the embodiment of the present application.
In some alternative embodiments, processing the message frame according to the anomaly type of the message frame includes: if the message frame lacks the frame header identification, the message frame is discarded; and/or if the message frame comprises a plurality of connected frame head identifiers, deleting the frame head identifier before the last frame head identifier in the message frame, and adding a first abnormal identifier in the message frame to obtain the processed message frame, wherein the first abnormal identifier is used for indicating that the message frame comprises a plurality of connected frame head identifiers.
The frame Header identifier (SOH) is a marker character located at the beginning Of the frame in the message frame, and the end Of frame identifier (EOT, end Of Transmission) is a marker character located at the last position Of the frame in the message frame, and is used to mark the beginning and end Of the message frame, respectively. The specific setting modes of the frame header identifier and the frame tail identifier can refer to related technologies, and are not repeated herein, and are all within the protection scope of the embodiments of the present application.
As shown in fig. 2, in the embodiment of the present application, after receiving a packet frame included in a packet, frame header identification detection may be performed on the packet frame. If the message frame lacks the frame header identification, discarding the message frame; if the message frame comprises a plurality of connected frame head identifiers, redundant frame head identifiers can be removed, and a first abnormal identifier is added, so that the processed message frame is obtained. Specifically, removing redundant frame header identifiers may delete the frame header identifier before the last frame header identifier, and only the last frame header identifier in the connected frame header identifiers is reserved.
Because the frame head identifier of the message frame is absent, the starting position of the message frame cannot be determined, and thus the message frame cannot be normally analyzed according to the frame head of the message frame. When the message frame is determined to comprise a plurality of connected frame head identifiers, redundant frame head identifiers can be deleted, so that the abnormal condition that the message frame comprises a plurality of connected frame head identifiers is repaired, the data in the message frame can be reserved later, and the loss condition of the data is reduced. In addition, the embodiment of the application can also mark the abnormal type that the message frame comprises a plurality of connected frame head identifiers through the first abnormal identifier, and can simply and conveniently determine the abnormal condition that the message frame comprises a plurality of connected frame head identifiers in the subsequent process through the first abnormal identifier, so that the efficiency of checking the message frame is improved.
In some alternative embodiments, processing the message frame according to the anomaly type of the message frame includes: if the message frame lacks the frame tail mark, adding the frame tail mark at the last of the message frame, and adding a second abnormal mark in the message frame to obtain a processed message frame; and/or if the message frame comprises a plurality of connected frame tail identifiers, deleting the frame tail identifier after the first frame tail identifier in the frame tail identifiers, and adding a third abnormal identifier in the message frame to obtain the processed message frame; the second abnormal identifier is an abnormal identifier indicating that the message frame lacks a frame end identifier, and the third abnormal identifier is an abnormal identifier indicating that the message frame comprises a plurality of connected frame end identifiers.
As shown in fig. 3, in the embodiment of the present application, after receiving a message frame included in a message, frame end identification detection may be performed on the message frame. If the message frame lacks the frame tail identifier, a second abnormal identifier and a frame tail identifier can be added at the end of the message frame; if the message frame comprises a plurality of connected frame tail identifiers, redundant frame tail identifiers can be removed, and a third abnormal identifier can be added, so that the processed message frame is obtained. Specifically, removing the redundant end-of-frame identifiers may delete the end-of-frame identifier after the first end-of-frame identifier, and only the first end-of-frame identifier in the connected end-of-frame identifiers is reserved.
In the embodiment of the application, when the frame end identifier of the message frame is determined to be absent, the frame end identifier is added to the last of the message frame, so that the abnormal condition that the frame end identifier of the message frame is absent is repaired; when the message frame is determined to comprise a plurality of connected frame head identifiers, redundant frame tail identifiers can be deleted, so that the abnormal situation that the message frame comprises a plurality of connected frame head identifiers is repaired; the processed message frames corresponding to the two abnormal types of message frames can be reserved later, so that the loss condition of data is reduced. In addition, the embodiment of the application can also mark the abnormal type of the message frame lacking the frame tail mark through the second abnormal mark, and mark the abnormal type of the message frame comprising a plurality of connected frame tail marks through the third abnormal mark, so that the two abnormal conditions can be simply and conveniently determined through the second abnormal mark and the third abnormal mark in the subsequent process, and the efficiency of checking the message frame is improved.
In some alternative embodiments, processing the message frame according to the anomaly type of the message frame includes: if the data length of the message frame is smaller than the length threshold value, a fourth abnormal identifier is added in the message frame to obtain the processed message frame, wherein the fourth abnormal identifier is an abnormal identifier indicating that the data length of the message frame is smaller than the length threshold value. And/or if the data length of the message frame is greater than the length threshold, discarding the part exceeding the length threshold after the frame head identification of the message frame, and adding a frame tail identification and a fifth abnormal identification to the rest part of the message frame to obtain the processed message frame; the fifth anomaly identification is an anomaly identification indicating that the data length of the message frame is greater than a length threshold value.
As shown in fig. 4, in the embodiment of the present application, after receiving a packet frame included in a packet, data length detection may be performed on the packet frame. If the data length of the message frame is smaller than the length threshold, the message frame can be temporarily not deleted, and a fourth abnormal identifier is added in the message frame to obtain the processed message frame; if the data length of the message frame is greater than the length threshold, the data shortening treatment can be performed on the message frame, for example, the part exceeding the length threshold after the frame head of the message frame is identified is discarded/deleted, and then the frame tail identification and the fifth abnormal identification can be added to the rest part of the message frame, so as to obtain the treated message frame. The length threshold may be determined according to a maximum number of bytes that can be transmitted by the device at one time in the packet transmission process, for example, the length threshold may be smaller than the maximum number of bytes, so that the data length of the processed packet frame obtained after adding the fifth exception identifier and the frame tail identifier does not exceed the maximum number of bytes.
In the embodiment of the present application, when it is determined that the data length of the packet frame is less than the length threshold, the packet frame may not be temporarily deleted, and a fourth abnormal identifier is added to the packet frame, so as to obtain a processed packet frame for subsequent use; when the data length of the message frame is determined to be greater than the length threshold, the part exceeding the length threshold after the frame head of the message frame is identified can be discarded, the data in the message frame is reduced, and the processed message frame is obtained, so that the processed message frame can be conveniently and normally transmitted. Therefore, the embodiment can reserve the processed message frames corresponding to the two abnormal types of message frames, thereby reducing the loss condition of data. In addition, the embodiment of the application can also mark the abnormal type of which the data length of the message frame is smaller than the length threshold value through the fourth abnormal identifier, and mark the abnormal type of which the data length of the message frame is larger than the length threshold value through the fifth abnormal identifier, so that the two abnormal conditions can be simply and conveniently determined through the fourth abnormal identifier and the fifth abnormal identifier in the subsequent process, and the efficiency of checking the message frame is improved.
In some optional embodiments, when obtaining the processed message frame, storing the processed message frame by the message storage unit includes: after the processed message frame is obtained, deleting the frame head mark and the frame tail mark of the processed message frame to obtain a first message frame field, and storing the first message frame field through a message storage unit.
And if the message frame is a normal message frame, storing the message frame by a message storage unit, including: if the message frame is a normal message frame, deleting the frame header identifier and the frame tail identifier of the message frame to obtain a second message frame field, and storing the second message frame field through a message storage unit.
It should be understood that in the process of sending the message frame with the corresponding storage address in the address set to the data receiving end according to the data acquisition request, the frame header identifier and the frame tail identifier may be added to the first message frame field and the second message frame field again, so as to obtain the previous processed message frame and the message frame determined to be the normal message frame, so as to send the processed message frame and the message frame determined to be the normal message frame to the data receiving end.
In the embodiment of the application, when the processed message frame and the normal message frame are stored, the frame head mark and the frame tail mark of the processed message frame and the normal message frame can be deleted, so that the storage space occupied by the processed message frame and the normal message frame is saved, and the utilization rate of the message storage unit is improved.
In order to facilitate understanding of the flow of packet processing according to the embodiments of the present application, the method provided in the present application is described below with reference to an alternative embodiment shown in fig. 5.
As shown in fig. 5, after receiving a message frame of a message, message frame detection may include frame header identification detection, frame tail identification detection, and data length detection, and after detecting that the message frame is an abnormal message frame, abnormal frame processing may be performed, including frame header abnormal processing, frame tail abnormal processing, frame length abnormal processing, and the like. It should be appreciated that frame header anomalies include a lack of a frame header identifier and include a plurality of concatenated frame header identifiers, etc., frame end anomalies include a lack of a frame end identifier and include a plurality of concatenated frame end identifiers, etc., and frame length anomalies include data lengths less than or greater than a length threshold, etc. After the processed message frame is obtained, a storage address is generated for the processed message frame.
If the message frame detection is performed to determine that the message frame is a normal message frame, a storage address can be directly generated for the message frame.
After generating the storage address, storing the message frame according to the storage address, that is, storing the processed message frame and the message frame determined to be the normal message frame into the message storage unit according to the storage address, wherein it should be understood that the storage addresses in the embodiment of the present application are all storage addresses corresponding to the storage area in the message storage unit; and filtering the storage address according to the filtering rule, namely selecting the storage address of the message frame which is determined to be the normal message frame, and selecting the storage address of the processed message frame which meets the filtering rule according to the filtering rule by the abnormal identifier.
After the message frame address filtering, address storage can be performed according to the selected storage address, namely, the storage address of the message frame determined to be the normal message frame is written into the address set in the address storage unit, and the storage address of the processed message frame including the abnormal identifier meeting the filtering rule is written into the address set in the address storage unit.
After receiving the data acquisition request for the message, according to the data acquisition request, acquiring a storage address from an address set in an address storage unit, and according to the acquired storage address, acquiring storage data of the storage address from the message storage unit, thereby acquiring a message frame corresponding to the storage address, and transmitting the acquired message frame to a data receiving end indicated by the data acquisition request. Reference may be made to the above embodiments for specific implementation of the embodiments of the present application, and details are not repeated here.
As an optional implementation manner, the message communication method provided in the embodiment of the present application may further include: and detecting the read-write state of the message storage unit, and if the ratio of the read speed of the message storage unit to the write speed of the message storage unit is smaller than a preset threshold value, discarding the message frame meeting the preset discarding condition.
The preset discard condition is used for indicating which type of message frame is discarded, for example, message frames with longer data length can be discarded, or some abnormal message frames can be discarded, so as to reduce the data quantity required to be stored by the message storage unit. It should be understood that the method provided in the embodiments of the present application may include detecting the data length of the packet frame, so as to identify the packet frame with a longer data length. When the message frames meeting the preset discarding conditions are discarded, the message frames meeting the preset discarding conditions can be discarded before being stored in the message storage unit, or the message frames meeting the preset discarding conditions can be discarded through discarding the storage addresses of the message frames meeting the preset discarding conditions after being stored in the message storage unit, which are all within the protection scope of the embodiment of the application. The preset threshold value can be set according to the read-write capability of the message storage unit, so that the storage unit can maintain a relatively high read-write speed.
It should be noted that, in some alternative embodiments, the flow of the message may also be detected, and if the flow of the message is greater than the flow threshold, the message frame meeting the above-mentioned preset dropping condition is dropped. The flow threshold value can also be set according to the read-write capability of the message storage unit, so that the storage unit can maintain a relatively high read-write speed.
When a message is transmitted, the condition of overlarge message flow is frequently encountered, and the overlarge message flow can cause the reduction of the reading speed of a message storage unit, thereby obviously influencing the efficiency of the message transmission. According to the method and the device, the reading and writing states of the message storage unit can be detected, when the ratio of the reading speed of the message storage unit to the writing speed of the message storage unit is smaller than the preset threshold value, before the storage address is stored through the address storage unit, the message frame meeting the preset discarding condition is discarded, so that the reading operation of the message storage unit is reduced, the reading speed of the message storage unit is improved, and the influence of overlarge message flow on the message transmission efficiency is reduced. And the method can selectively discard some message frames without discarding all the message frames by setting the condition meeting the preset discard condition, thereby increasing the flexibility of message transmission and reducing the lost data.
According to a third aspect of the embodiments of the present application, as shown in fig. 6, there is provided a packet communication device, including:
the receiving judging module 601 is configured to receive a plurality of message frames included in the message, and respectively check each message frame to determine whether the message frame is an abnormal message frame;
