In order to ensure the information security, an upper computer is required to transmit an image input into the upper computer to a server for backup, the upper computer sends the image input into the upper computer to the server in a mode that the upper computer independently encapsulates each image input into the upper computer into an information message and then sends the information message to the server, and the information message is sent to the server to ensure the rapidness, the high efficiency and the correctness, and the mode that the information message is sent to the server to ensure the correctness is that the information message is sent again if the information message is lost; however, when the information link is accidentally lost or blocked for a short period of time due to the mode of retransmitting the information message if the information message is lost, the information link for transmitting the information message cannot be quickly changed, so that the rapidness, the efficiency and the correctness of the information message transmission cannot be better ensured.
The upper computer sends the image input into the upper computer to a server for storage;
the mode that the upper computer sends the images input into the upper computer to the server is that the upper computer independently encapsulates each image input into the upper computer into an information message and then sends the information message to the server;
the mode of sending the information message to the server comprises the following steps:
s1: the upper computer transmits an information message to the server;
s2: if the response message of the server to the information message is not obtained within the set duration, adding a transfer guide mark in the information message, wherein the transfer guide mark is used for indicating the transfer mode of the information message;
the set time length can be determined by the tolerance threshold value of the longest time length from the time when the upper computer transmits the information message to the server for the first time until the upper computer obtains the response message transmitted by the server to the upper computer and obtains the information message; the tolerance threshold is the time which can be reached after the longest time length from the time when the upper computer first transmits the information message to the server until the upper computer obtains the response message transmitted by the server to the upper computer and the information message is obtained is added with 5 seconds. The final time of the set duration is lower than the time;
just like, setting a tolerance threshold as K, wherein the time that can be reached after the longest time that the upper computer first transmits the information message to the server until the upper computer obtains a response message that the server transmits the information message to the upper computer plus 5 seconds is the last time that the upper computer first transmits the information message to the server until the upper computer obtains a response message that the server transmits the information message to the upper computer is the last time that is L, wherein K is greater than L, then when the time of waiting for the response message is greater than L, re-transmission is performed on the information message, so that the time of re-transmission is limited between 0 and the value obtained by subtracting L from K, and the information message obtained by the server is still fast and efficient after re-transmission.
S3: and performing retransmission on the information message by means of the transmission guide mark.
And if the upper computer does not obtain the response message of the server to the information message within the set time length, the information message is retransmitted by adding a transmission guide mark for indicating the transmission mode of the information message in the information message transmitted to the server. Thus, when the sporadic information message of a short period of time is lost and blocked on an information link, the information link for information message transmission can be quickly changed by the transmission guide mark, so that the message transmission can be fast, efficient and correct.
The transfer guide token can be a number indicator of how many times the token is transferred again.
The transmission guide token may be a retransmission token, and performing retransmission of the information packet by the transmission guide token in S3 may include:
and by means of the retransmission marks, one information link is selected again or information messages are retransmitted on a plurality of information links.
If the response message of the server to the information message is not obtained within the set time length for the first time, one information link can be selected from other information links to transmit the information message again; if the response message of the server to the information message is still not obtained within the set duration after the information message is transmitted again on one information link selected from other information links, the information message can be transmitted again on a plurality of information links later; when the information message is transmitted again on a plurality of information links later, the information message can be transmitted again on the plurality of information links simultaneously, or the information message can be transmitted again on the plurality of information links one by one.
The transmission guide mark may be a number flag indicating how many times the information message is transmitted, and the re-transmitting the information message by the transmission guide mark in S3 may include:
and executing retransmission on the information message by means of the number of times of transmission in the number mark of the number of times of transmission.
Depending on the number of times in the number of times passed flag, performing a corresponding retransmission of the information packet can include:
if the number of times of transmission is one, transmitting the information link transmitted before the information message again;
if the number of times of transmission is less than three and more than one, one information link is selected or the information message is transmitted again on a plurality of information links;
if the number of times of transmission is more than or equal to three, the information message is transmitted again on a plurality of information links.
The information message can be transmitted again by using another mode according to the number of times in the number mark of the number of times of transmission;
depending on the number of times in the number of times passed flag, performing a retransmission of the information packet can further include:
if the number of times of transmission is one, selecting an information link to transmit the information message again;
if the number of times of transmission is more than one, the information message is transmitted again on a plurality of information links.
The method for information message transmission can further comprise:
determining that the information message is not to be retransmitted by means of a tolerance threshold value of the longest duration from the time when the upper computer first transmits the information message to the server until the upper computer obtains a response message that the server transmits the information message to the upper computer:
if the final time of the time length required by the advance estimation of retransmitting the information message to the server is lower than the tolerance threshold value of the longest time length, a transmission guide mark is additionally arranged in the information message;
selecting a corresponding information link which can transmit the information message to the server again and has the estimated time length required in advance and the final time lower than the tolerance threshold value of the longest time length to perform retransmission by means of the tolerance threshold value of the longest time length;
and if the final time of the time length required by the advance estimation for retransmitting the information message to the server is not lower than the tolerance threshold value of the longest time length, the task of retransmitting the information message is not executed any more.
The structure of sending the information message to the upper computer of the server is divided into three stages: an encapsulation stage, a transport stage, and a link stage, where,
and (3) packaging stage: independently packaging each image input into the upper computer into an information message;
a transmission stage: the server identifies the information message obtained by the upper computer, namely transmits a response message to the upper computer; the upper computer executes sequencing on the transmitted information messages in a serial number marking mode, starts timing when transmitting the information messages and executes retransmission on the information messages when the information messages need to be retransmitted;
and (3) link level: one or more information links are selected to forward information messages delivered by the delivery stage to the server.
During the transmission of the information message, if the upper computer transmits the information message to the server through an information link for the first time and does not obtain the response message of the server to the information message within the set time length for the first time, the transmission level of the upper computer adds a transmission guide mark for indicating the transmission mode of the information message in the information message and transmits the transmission guide mark to the link level; after the link level obtains the transfer guide mark, the link level can perform re-transfer on the information message by means of the transfer guide mark.
It is also possible to integrate the encapsulation stage with the delivery stage, only to ensure that the link stage can obtain information messages, whether they need to be delivered again.
Here, the tolerance threshold is set to be K, which is the time that can be reached after 5 seconds are added to the longest time that the upper computer first transmits the information message to the server until the upper computer obtains a response message that the server transmits the information message to the upper computer, and the final time that the upper computer first transmits the information message to the server until the upper computer obtains the response message that the server transmits the information message to the upper computer is L, where K is greater than L, so that when the time of waiting for the response message is greater than L, re-transmission is performed on the information message, and thus the time of re-transmission is limited between 0 and the value obtained by subtracting L from K, so as to ensure that the information message obtained by the server is still fast and efficient after re-transmission.
Thus, the performance of fast, efficient and correct message transmission can be obtained when occasional message loss and blocking occurs in a short period of time on an information link.
Concurrently, the upper computer has little benefit in utilizing the efficiency of the information links, as compared to simply passing the message over one or a combination of several information links to improve the accuracy of the pass.
In addition, compared with the mode of transmitting the test message of the test information link between the upper computer and the server when the test information message is packaged into one information message, the upper computer has better adaptability in the mode (the test message does not need to be used between the upper computer and the server for testing).
The mode that the upper computer sends the images input into the upper computer to the server is that the upper computer independently encapsulates each image input into the upper computer into an information message and then sends the information message to the server;
the upper computer comprises a transmission program and a control program;
here:
a transfer program for transferring the information message towards the server;
the control program is used for adding a transmission guide sign in the information message if the transmission program does not obtain the response message of the server to the information message within the set time length, and the transmission guide sign is used for indicating the transmission mode of the information message;
and the transfer program is also used for performing re-transfer on the information message by virtue of the transfer guide mark additionally arranged on the control program.
Here, the set time length can be determined by a tolerance threshold value of the longest time length from the time when the upper computer first transmits the information message to the server until the upper computer obtains a response message that the server transmits the information message to the upper computer. The tolerance threshold is the time which can be reached after the longest time length from the time when the upper computer first transmits the information message to the server until the upper computer obtains the response message transmitted by the server to the upper computer and the information message is obtained is added with 5 seconds. The final time of the set duration is below that time.
The manipulation program can be used to:
determining that the information message is not to be retransmitted by means of a tolerance threshold value of the longest duration from the time when the upper computer first transmits the information message to the server until the upper computer obtains a response message that the server transmits the information message to the upper computer:
if the final time of the time length required by the advance estimation of retransmitting the information message to the server is lower than the tolerance threshold value of the longest time length, a transmission guide mark is additionally arranged in the information message;
selecting a corresponding information link which can transmit the information message to the server again and has the estimated time length required in advance and the final time lower than the tolerance threshold value of the longest time length to perform retransmission by means of the tolerance threshold value of the longest time length;
and if the final time of the time length required by the advance estimation for retransmitting the information message to the server is not lower than the tolerance threshold value of the longest time length, the task of retransmitting the information message is not executed any more.
And the upper computer executes the retransmission of the information message by means of a mode for activating the upper computer, and if the transmission program does not obtain the response message of the server to the information message within the set time length, the upper computer executes the retransmission of the information message by adding a transmission guide mark for indicating the transmission mode of the information message in the information message transmitted to the server. Thus, when the sporadic information message of a short period of time is lost and blocked on an information link, the information link for information message transmission can be quickly changed by the transmission guide mark, so that the message transmission can be fast, efficient and correct.
The transfer guide token is a re-transfer token, and the transfer program is operable to:
and by means of the retransmission marks, one information link is selected again or information messages are retransmitted on a plurality of information links.
The transfer guide token is a quantity flag of how many times the transfer is made, and the transfer program can be used to:
and executing retransmission on the information message by means of the number of times of transmission in the number mark of the number of times of transmission.
The delivery program can be used to:
if the number of times of transmission is one, transmitting the information link transmitted before the information message again;
if the number of times of transmission is less than three and more than one, one information link is selected or the information message is transmitted again on a plurality of information links;
if the number of times of transmission is more than or equal to three, the information message is transmitted again on a plurality of information links.
Thus, the performance of fast, efficient and correct message transmission can be obtained when occasional message loss and blocking occurs in a short period of time on an information link.
Concurrently, the upper computer has little benefit in utilizing the efficiency of the information links, as compared to simply passing the message over one or a combination of several information links to improve the accuracy of the pass.
In addition, compared with the mode of transmitting the test message of the test information link between the upper computer and the server when the test information message is packaged into one information message, the upper computer has better adaptability in the mode (the test message does not need to be used between the upper computer and the server for testing).
