It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
An execution main body of the message transmission method may be the message transmission device provided in the embodiment of the present invention, or a computer device integrated with the message transmission device, where the message transmission device may be implemented in a hardware or software manner.
Referring to fig. 1, in an embodiment, the computer device may have an a port and a B port, and both the a port and the B port are bidirectional ports, that is, the computer device can receive data and can send data. When the port A receives a message, the port A is the first port mentioned in the embodiment of the invention, and the port B is the second port mentioned in the embodiment of the invention; when the port B receives a message, the port B is the first port mentioned in the embodiment of the present invention, and the port a is the second port mentioned in the embodiment of the present invention, where sending data from the first port to the second port is data downlink, and sending data from the second port to the first port is data uplink; the computer device itself also has a plurality of data buffers for processing data required by the computer device itself.
Fig. 1 is a schematic view of an application scenario of a message transmission method according to an embodiment of the present invention, taking an example that a message transmission apparatus is integrated in a computer device, the computer device may receive a message through a first port of the computer device; sending the message to the second equipment through the second port while receiving the message; checking the message to obtain a checking result; acquiring corresponding target data according to the message, and storing the target data in a cache region; and correspondingly processing the target data in the cache region according to the verification result, and sending the data to be transmitted in the cache region to the target equipment.
Referring to fig. 2, fig. 2 is a flowchart illustrating a message transmission method according to an embodiment of the present invention. The specific flow of the message transmission method provided by the embodiment of the invention can be as follows:
s201, receiving a message through a first port of first equipment.
In this embodiment, the first device refers to the computer device itself, that is, the computer device receives the message through the first port. For example, when the computer device is an audio device, it receives voice information transmitted from a microphone or the like.
S202, sending the message to the second device through the second port while receiving the message.
And the computer equipment sends the message to the second equipment through the second port with preset time delay while receiving the message at the first port. Wherein, the preset time delay can be freely set.
S203, the message is verified to obtain a verification result.
Specifically, integrity Check and Cyclic Redundancy Check (CRC) Check are performed on the message to obtain a Check result, where the Check result is that the message is successfully checked or the message is failed to be checked.
It should be noted that, because the computer device in this embodiment does not need to receive the entire message to the receiving buffer through the first port, and then check the message, when the message is successfully checked, the message in the receiving buffer is transferred to the sending buffer, and finally the data is sent out through the second port. The message is received through the first port, and simultaneously, the message is transmitted to the second device through the second port, and the message is checked, so that the message is checked while the message is received, and meanwhile, the message is transmitted while the message is received, although some time delay is generated in the transmission process, the time delay is small and can be freely set, for example, the time delay can be 48ns, so that the message is basically transmitted while the message is received.
It will be appreciated that the message contains a plurality of fields, which may include data fields for storing data content and check fields for storing check information. After the computer device in this embodiment obtains the verification result, the verification information in the message may also be updated according to the verification result. For example, when receiving a message through a first port of a computer device, the computer device sends the message to a second device through a second port of the computer device, and checks the received message to obtain a check result, and then updates a check field in the message according to the check result, that is, the check information in the original message check field is replaced with the check information obtained after the message is checked by the computer device, where the check information may include a message check success or a message check failure, and since the existing device needs to check the message after receiving the message, the message can be sent out only after the check success, and when the check fails, the message is discarded and the check information in the message check field is not updated. Compared with the existing equipment, the computer equipment can send out the message more quickly, and can enable other equipment receiving the message to know the correctness of the message in time, so that the time delay of message transmission is reduced to a certain extent.
And S204, acquiring corresponding target data according to the message, and storing the target data in a cache region.
As shown in fig. 1, a functional node, which may be an AEDP node for acquiring corresponding target data or inserting corresponding target data, may be added using a direct insertion or extraction technique (AEDP).
For example, when the computer device receives a message from the first port, the size of a data block may be preset according to data required by the computer device itself, a window may be established according to the size of the preset data block, the window may be controlled to slide on the message, when the sliding position of the window is a second preset position, the data to be acquired corresponding to the second preset position may be acquired, the target data may be acquired, and the target data may be stored in the cache region. The second preset position may be determined by obtaining data required by the computer device itself, that is, when the device needs what data, the window slides to the corresponding position, and then intercepts the data at the corresponding position, and stores the data in the cache region.
For example, when the computer device receives a message from the second port, step S204 may be to obtain, according to the message, corresponding data to be inserted in the buffer, and specifically may be: establishing a data block according to-be-inserted data to be inserted into the computer equipment, then establishing a window according to the size of the preset data block, controlling the window to slide on the message, inserting the corresponding to-be-inserted data when the sliding position of the window is a first preset position to obtain target data, and sending all to-be-transmitted data including the target data in a cache region to the target equipment, wherein the first preset position can be the tail part of the message.
S205, correspondingly processing the target data in the cache region according to the verification result, and sending the data to be transmitted in the cache region to the target device.
And when the message is successfully verified, sending the data to be transmitted in the cache region to target equipment, wherein the data to be transmitted in the cache region comprises the target data. And when the message check fails, clearing the target data in the cache region.
Particularly, when the message is successfully verified, the first port is arranged to receive a correct mark; when the message check fails, the first port is set to receive the error mark.
As can be seen from the above, in this embodiment, a message is received through the first port of the first device; sending the message to the second equipment through the second port while receiving the message; checking the message to obtain a checking result; acquiring corresponding target data according to the message, and storing the target data in a cache region; and correspondingly processing the target data in the cache region according to the verification result, and sending the data to be transmitted in the cache region to the target equipment. Compared with the prior method for transmitting the message by the Ethernet technology, the embodiment of the invention can reduce the time delay of message transmission and eliminate the time delay jitter of message transmission, and realizes the transmission of the message with low time delay and no time delay jitter.
The message transmission method of the present invention will be further described below on the basis of the method described in the above embodiment. Referring to fig. 3, the message transmission method may include:
s301, receiving the message through the first port of the first device.
In the embodiment of the present invention, the first device refers to the computer device itself, that is, the computer device receives the packet through the first port. For example, when the computer device is an audio device, it receives voice information transmitted from a microphone or the like.
S302, when receiving the message, sending the message to the second device through the second port.
And the computer equipment sends the message to the second equipment through the second port with preset time delay while receiving the message at the first port. Wherein, the preset time delay can be freely set.
S303, verifying the message to obtain a verification result.
Specifically, integrity Check and Cyclic Redundancy Check (CRC) Check are performed on the message to obtain a Check result, where the Check result is that the message is successfully checked or the message is failed to be checked.
Different from the traditional message transmission of checking before sending, the embodiment can simultaneously send out the message with the preset time delay when receiving the message and check the message, so that the corresponding message is also checked when the message is received; because the preset time delay is small and can be freely set according to requirements, when the message is received, the message is correspondingly sent out.
And S304, updating the verification information in the message according to the verification result.
Wherein, the message includes: the verification information, after obtaining the verification result, may further include: and updating the verification information in the message according to the verification result.
It will be appreciated that the message contains a plurality of fields, which may include data fields for storing data content and check fields for storing check information. After the computer device in this embodiment obtains the verification result, the verification information in the message may also be updated according to the verification result. For example, when receiving a message through a first port of a computer device, the computer device sends the message to a second device through a second port of the computer device, and checks the received message to obtain a check result, and then updates a check field in the message according to the check result, that is, the check information in the original message check field is replaced with the check information obtained after the message is checked by the computer device, where the check information may include a message check success or a message check failure, and since the existing device needs to check the message after receiving the message, the message can be sent out only after the check success, and when the check fails, the message is discarded and the check information in the message check field is not updated. Compared with the existing equipment, the computer equipment can send out the message more quickly, and can enable other equipment receiving the message to know the correctness of the message in time, so that the time delay of message transmission is reduced to a certain extent.
S305, establishing a window according to the size of the preset data block, and controlling the window to slide on the message.
As shown in fig. 1, a functional node, which may be an AEDP node for acquiring corresponding target data or inserting corresponding target data, may be added using a direct insertion or extraction technique (AEDP).
The size of the preset data block can be determined according to the data required by the computer device, so that when the computer device receives the message, a window can be established according to the size of the preset data block, and the window is controlled to slide on the message, so as to obtain the data required by the computer device.
S306, when the current sliding position of the window is a second preset position, acquiring data to be acquired corresponding to the second preset position to obtain target data, and storing the target data in a cache region.
When the data is downlink, when the current sliding position of the window is a second preset position, acquiring data to be acquired corresponding to the second preset position, acquiring target data, and storing the target data in the cache region, wherein the second preset position can be any position of the message data part and can be determined by the amount of data required by the computer device.
When the data is uplink, step S306 may be: and when the current sliding position of the window is a first preset position, inserting data to be inserted, which needs to be inserted, into the computer equipment to obtain target data, wherein the first preset position can be the tail of the message.
S307, when the message check fails, target data in the cache region is cleared, and the data to be transmitted in the cache region is divided into a plurality of pieces of sub data to be transmitted.
S308, when the message is successfully verified, dividing the data to be transmitted (including the target data) in the buffer into a plurality of pieces of sub data to be transmitted.
Step S307 and step S308 may specifically be: when the message check fails, a receiving port is set to receive an error mark, target data stored in a cache region is cleared, and data to be transmitted in the cache region is divided into a plurality of pieces of sub data to be transmitted for transmission. When the message is successfully verified, the receiving port is set to receive the correct mark, the data to be transmitted (including the target data) in the cache region is divided into a plurality of sub data to be transmitted, and the data to be transmitted is transmitted after the successful reception is confirmed every time one data is transmitted, so that the accuracy is improved.
It can be understood that the data to be transmitted originally exists in the cache region, and therefore, whether the target data is stored in the cache region as the data to be transmitted or not, the data to be transmitted originally exists in the cache region needs to be sent to the target device.
S309, sequencing the data to be transmitted of the multiple sub-channels to form a transmission sequence.
In this step, the data to be transmitted is sorted according to the position of each sub data to be transmitted in the data to be transmitted, so that the data sequence in each sub data to be transmitted is the same as the data sequence in the data to be transmitted.
S310, setting the data to be transmitted of the first sub-sequence in the transmission sequence as the data to be transmitted of the current sub-sequence.
S311, sending the current sub data to be transmitted to the target equipment through a plurality of first channels.
And each sub-channel to be transmitted transmits the data once through each first channel.
In this step, the number of the first channels is 8, for example, so that each sub-data to be transmitted is transmitted once through each first channel in turn, for a total of 8 times. And after each sub-to-be-transmitted data is sent (8 times of sending through 8 channels in total), and the target equipment confirms that the sub-to-be-transmitted data is successfully verified, sending the next sub-to-be-transmitted data.
And S312, receiving response information returned by the target equipment.
The response information is generated after the target device receives the current sub-to-be-transmitted data and verifies the current sub-to-be-transmitted data, when any current sub-to-be-transmitted data is verified successfully, the response information is returned successfully, and when all the current sub-to-be-transmitted data are verified successfully, the response information is returned failed. And for the data to be transmitted of the current sub, checking one data to be transmitted of each received data, when the data to be transmitted of one current sub is successfully checked, displaying that the carried information of the data to be transmitted of the current sub is complete and correct, directly judging that the data to be transmitted of the current sub is successfully checked, stopping checking, automatically ignoring the data to be transmitted of the current sub received through other channels, and returning successful response information. And when the data to be transmitted of the sub-channels received through the 8 channels are verified to be failed, judging that the transmission is wrong, and returning failure response information.
And S313, deleting the sub-to-be-transmitted data set as the current sub-to-be-transmitted data from the transmission sequence when the successful response information is received.
And S314, judging whether the transmission sequence has data to be transmitted or not after deletion.
And S315, if the data to be transmitted does not exist, the data to be transmitted is judged to be transmitted completely.
If so, step S310 is performed.
And S316, confirming at least one currently available second channel when the failure response information is received.
In this case, there is a possibility that the current first channel is not clear or there is interference, and therefore the second channel needs to be changed for transmission. The number of the second channels may be one or more.
S317, closing the current multiple first channels, setting the multiple second channels as the first channels, and after the setting is finished, executing the step of sending the current sub-to-be-transmitted data to the target device through the multiple first channels.
As can be seen from the above, in this embodiment, a message is received through the first port of the first device; sending the message to the second equipment through the second port while receiving the message; checking the message to obtain a checking result; acquiring corresponding target data according to the message, and storing the target data in a cache region; and correspondingly processing the target data in the cache region according to the verification result, and sending the data to be transmitted in the cache region to the target equipment. Compared with the prior method for transmitting the message by the Ethernet technology, the embodiment of the invention can reduce the time delay of message transmission and eliminate the time delay jitter of message transmission, and realizes the transmission of the message with low time delay and no time delay jitter.
Furthermore, in this embodiment, the computer device divides the data to be transmitted in the buffer into multiple pieces of sub-data to be transmitted; sequencing a plurality of pieces of data to be transmitted to form a transmission sequence; sequentially sending each sub data to be transmitted to target equipment through a plurality of first channels according to a transmission sequence, wherein each sub data to be transmitted is sent once through each first channel; therefore, the transmission of the data to be transmitted in the buffer area is completed, and each sub-data to be transmitted is sent for multiple times through a plurality of different first channels, so that the accuracy of data transmission is greatly improved, the stability of transmission delay is ensured, and rapid transmission jitter is avoided under the condition of poor network.
In an embodiment, a message transmission method is further provided, and the method may be applied to various scenarios, please refer to fig. 4, taking the case that the method is applied to an audio data transmission scenario as an example, where the computer device b may be one or more, may exist in a separate form, or may be integrated in a device such as a sound device, and the present embodiment takes the case that the computer device b exists in a separate form as an example.
In the audio data transmission scenario, the computer device b may receive a message through the first port, where the message may be received by the computer device b from another device through the first port, for example, receiving voice information sent by a microphone; then, the computer device b sends the message to a second device through a second port while receiving the message, wherein the second device can be a sound c or other relay devices; meanwhile, the message is checked to obtain a check result; then establishing a window according to the requirement of the computer equipment b or the size of a preset data block, sliding in the message received by the first port, and after sliding to a set position, extracting target data required by the computer equipment b and storing the target data in a cache region of the computer equipment b; and then waiting for the end of message reception, completing message verification while completing message reception, and when the message verification is successful, setting a first port to receive a correct mark, moving the data to be transmitted in the buffer area of the computer equipment b into a receiving queue buffer area, and transmitting the data through a set interface, wherein the data to be transmitted in the buffer area of the computer equipment b can be transmitted to the sound c by the computer equipment b, and can also be transmitted to other equipment. When the message check fails, the first port is set to receive the error mark, the target data in the cache region of the computer device b is cleared, the data to be transmitted in the cache region of the computer device b is moved to the receiving queue buffer region, and the data is sent out through the set interface. It can be understood that, no matter whether the received message verification result is successful or failed, the data to be transmitted may exist in the receive queue buffer, and therefore, no matter whether the received message verification result is successful or failed, the data to be transmitted in the receive queue buffer needs to be sent out, and only when the message reception is successful, the target data acquired by the computer device b needs to be sent out together.
In the audio data transmission scenario, the computer device b may also receive a message through the first port, where the message may be received by the computer device b from another device through the first port, for example, receiving voice information sent by a microphone; then, the computer device b sends the message to a second device through a second port while receiving the message, wherein the second device can be a sound device or other relay devices; meanwhile, the message is checked to obtain a check result; then, according to the requirement of the computer device b or the size of a preset data block, establishing a window, sliding in the message received by the first port, and after sliding to a set position, inserting the data to be inserted into the computer device b, which can be generally inserted into the tail of the message; then waiting for the end of message receiving, completing message verification while completing message receiving, setting a first port to receive a correct mark when message verification is successful, and setting a first port to receive an error mark when message verification is failed; the data to be transmitted, including the inserted data, and the corresponding data check value may then be sent to stereo c or other devices.
As can be seen from the above, the embodiment receives the message through the first port of the computer device; sending the message to the second equipment through the second port while receiving the message; checking the message to obtain a checking result; acquiring corresponding target data according to the message, and storing the target data in a cache region; and correspondingly processing the target data in the cache region according to the verification result, and sending the data to be transmitted in the cache region to the target equipment. The embodiment of the invention transmits the message and processes the data at the same time when receiving the message, thereby saving the processing time, simultaneously ensuring that the time for transmitting and receiving the message does not depend on the message length, and realizing the low-delay and non-delay jitter transmission of the message.
In an embodiment, a message transmission apparatus is also provided. Referring to fig. 5, fig. 5 is a schematic structural diagram of a message transmission apparatus according to an embodiment of the present invention.

For example, when receiving a message through a first port of a computer device, the computer device sends the message to a second device through a second port of the computer device, and checks the received message to obtain a check result, and then updates a check field in the message according to the check result, that is, the check information in the original message check field is replaced with the check information obtained after the message is checked by the computer device, where the check information may include a message check success or a message check failure, and since the existing device needs to check the message after receiving the message, the message can be sent out only after the check success, and when the check fails, the message is discarded and the check information in the message check field is not updated. Compared with the existing equipment, the computer equipment can send out the message more quickly, and can enable other equipment receiving the message to know the correctness of the message in time, so that the time delay of message transmission is reduced to a certain extent.
