Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The data reliable transmission method provided by the application can be applied to the application environment shown in fig. 1. The system comprises a server 104, a sending end 102 and a receiving end 106, wherein the sending end 102 and the receiving end 106 realize data communication through the server 104. Specifically, the sending end 102 sends the message data to the server 104 through the sending terminal, and stores and forwards the message data to the receiving end 106 through the server 104, where the receiving end 106 is a receiving terminal that obtains the message data. The sender 102 and the receiver 106 may be, but are not limited to, various personal computers, laptops, smartphones, tablets, and portable wearable devices, and the server 104 may be implemented by an independent server 104 or a server 104 cluster composed of a plurality of servers 104.
The server 104 runs on a memory block 108, where the memory block 108 is used to store message data sent by the sender 102, and when the receiver 106 finds that the message data is lost, the receiver will send a data loss feedback to the sender 102 to apply for retransmission of the message data that was lost before the sender 102.
In one embodiment, as shown in fig. 2, a method for reliable data transmission is provided, which is described by taking the method as an example applied to the server in fig. 1, and includes the following steps:
step S202, receiving message data sent by the sending end.
The sending end is a sending terminal for sending message data to the server, a user inputs the message data to the sending end, and the sending end sends the message data to the receiving end.
Specifically, the server receives message data sent by the sending end, taking stock investment in financial industry as an example, the message data is transaction data performed by a large number of users through the sending end, and the transaction data comprises stock names, purchase counts, share of each stock purchase and the like.
Step S204, storing the message data in a memory block.
The memory block is located on the server and can be used for storing message data forwarded by the sending end to the receiving end through the server.
Specifically, after receiving message data sent by a sending end, a server may store a certain amount of message data, the time length of each message data stored in a memory block is set, when the message data is non-sensitive data, such message data may not need to be stored in the memory block, if the message data is stored in the memory block, a preset retention time may be set, and when the message data reaches the preset retention time, the message data is timely cleaned to reduce the memory load of the memory block. The non-sensitive data is message data which is relatively insensitive to data loss in the data transmission process based on a service scene at a receiving end relative to the sensitive data.
Step S206, sending the message data to a receiving end, and resending the message data from the memory block to the receiving end when the message data is sensitive data and data loss feedback sent by the receiving end is received.
When the message data is sensitive data, the message data can be stored in the memory block, the time length of the sensitive data stored in the memory block can also be set, and in order to realize retransmission of the message data as much as possible, the retention time of the sensitive data in the memory block is not limited under more conditions. In addition, in order to avoid the situation that the memory of the memory block is insufficient, the sensitive data is usually cleared from the memory block after the server determines that the sensitive data has been retransmitted to the receiving end.
Specifically, in a process of processing a service scene, when a receiving end receives a first piece of message data forwarded by a server, the receiving end informs the server that the message data is sensitive data or non-sensitive data. If the message data is sensitive data, when the receiving end loses the data, the receiving end sends data loss feedback to the server to inform the server that the data loss occurs, and the server needs to retransmit the lost message data. When receiving the data loss feedback, the server will resend the message data from the memory block to the receiving end, and resend the message data missed by the receiving end due to network outage.
In the above data reliable transmission method, the server receives the message data sent by the sending end, and then synchronously forwards the message data to the receiving end, and at the same time, the server stores each message data in the memory block on the server. When the receiving end has data loss, that is, when the receiving end does not receive the message data due to network congestion or interruption, if the message data belongs to sensitive data, the receiving end will send data loss feedback to the sending end, and the server receives and responds to the data loss feedback, and sends the stored message data to the receiving end from the memory block, so that the receiving end can compensate the previously lost message data, and the integrity of the message data received by the receiving end is ensured. Therefore, the method and the device can ensure that the message can be reliably delivered when the network is congested or interrupted.
In one embodiment, the message data is numbered message data, and the number of the message data is obtained by continuously numbering the message data to be sent by a sending end; the data loss feedback is sent at the receiving end when the number of the message data received at the next time is not continuous with the number of the last message data.
The message data received by the server is the message data with a number, and the numbering process occurs at the sending end. The sending end generates a corresponding sequence number every time the sending end sends a message data, and the message data numbers are continuous. The content of the message data is written on the memory block in a tail additional mode, and a new memory block is created when the size of the memory block reaches a certain size; while writing the file, the number of the message data, the name of the memory block, and the offset position and length information of the message data within the memory block are recorded in another index file. And performing associated indexing according to the number of the message data and the memory block, and quickly positioning the memory block where the corresponding message data is located and the offset in the memory block by accessing the index file.
The data loss feedback may be, but is not limited to, a NACK request, which is taken as an example, and the NACK message is sent to the server when the receiving end detects data loss. And the server finds the corresponding message data in the memory block according to the sequence number in the NACK message and sends the message data to the receiving end again.
Specifically, since the sending end continuously numbers the message data to be sent, the receiving end obtains the message data and also obtains the number of the message data. When data is lost, according to the fact that the serial number of the message data received at the current time is not continuous with the serial number of the previous message data, the receiving end sends data loss feedback to the server when monitoring the discontinuous situation. For example, the number of the last received message data is D44, when the next received message data, if the message data next to the last received message data, should theoretically be D45, but if there is a loss of message data in the intermediate transmission, when the number of the next received message data may be D48 or D59, etc., and there is a significant numbering interval with D44, there is a data loss at the receiving end, and when the data is sensitive data, a data loss feedback is sent to the server.
In this embodiment, the message data is continuously numbered by the sending end, the receiving end compares the number of the message data received this time with the number of the previous message data, and when the discontinuity is found, the data loss feedback is sent to the server, so that the accuracy of sending the data loss feedback by the receiving end is improved.
In one embodiment, the message data is tagged message data; the method further comprises the following steps:
receiving window information sent by the sending end, wherein the window information comprises a mark of message data;
sending the window information to the receiving end;
the data loss feedback is sent when the mark of the message data received at the receiving end is inconsistent with the mark of the message data acquired through the window information.
The window information is sent to the server by the sending end and then sent to the receiving end by the server, the window information comprises a mark of the message data, and the mark of the message data comprises the number of the current latest message data and the like. The window information is periodically sent to the server by the sending terminal.
Specifically, the server receives the window information sent by the sending end, and forwards the window information to the receiving end, and when determining whether data loss occurs, the receiving end compares whether the mark of the message data received at the time and the mark of the message data acquired through the window information are consistent. When the message data does not match with the message data that should be received at the time, it is indicated that the message data received at the time and the message data that should be received at the time are not the same message data, and therefore, the receiving end will send data loss feedback to the server. For example, the mark of the message data includes the number of the current latest message data, and when the server forwards the message data, the server sends the latest message data to the receiving end, and at the same time, sends the number of the latest message data to the receiving end. Therefore, the receiving end can compare whether the number of the message data received at the current time is consistent with the number of the latest message data, if so, the message data received at the current time is the latest message data, the intermediate transmission process is not lost, and if not, the message data loss exists in the intermediate transmission process.
In this embodiment, the server receives the window information of the sending end, and sends the window information to the receiving end, so that the receiving end sends data loss feedback to the server when the mark of the message data received by the receiving end at the time is inconsistent with the mark of the message data acquired through the window information.
In one embodiment, before receiving the data loss feedback sent by the receiving end, the method further includes:
receiving a data loss coping strategy sent by the receiving end;
when the message data is sensitive data and data loss feedback sent by the receiving end is received, the method further comprises the following steps: and determining that the data loss of the sensitive data should be a policy that data loss is not allowed, and based on the policy that data loss is not allowed, resending the message data from the memory block to the receiving end.
After the receiving end receives the first piece of message data sent by the sending end, the receiving end sends a data loss coping strategy to the server. The sensitive data mainly refers to reliability sensitive data, the reliability sensitive data comprises real-time sensitive data and non-real-time sensitive data, the reliability sensitive data is non-sensitive data relative to the sensitive data, and the non-sensitive data is data insensitive to data loss. Non-sensitive data also includes real-time sensitive data and non-real-time sensitive data. The real-time sensitive data refers to that a receiving end is very sensitive to real-time acquisition of message data in a service scene A, such as latest market exhibition. The reliable delivery of the message data is very sensitive to the receiving end in the B service scene, and the reliable delivery means that the message data can be completely received by the receiving end and cannot be lost in the transmission process. For example, transaction data archiving has low requirements on real-time performance, but has high requirements on integrity of message data, so that the message data received by the receiving end is reliability sensitive data. The reliability sensitive data can also be called lost sensitive data generally, and when reliable delivery is realized, as long as the receiving end can receive all message data, a fast transmission path can be selected, and a slow transmission path can also be selected. Generally, real-time sensitive data selects a fast transmission path and non-real-time sensitive data selects a slow transmission path. Because the fast transmission path allows the receiving end to receive lost message data more quickly than the slow transmission path. In some service scenarios, the reliability and the real-time performance of the message data are sensitive, for example, a transaction engine and the like, and the message data is reliably delivered while being transmitted through a fast transmission path.
Specifically, when the receiving end judges that the message data is sensitive data, the receiving end sends data loss feedback to the server. When the server receives the data loss feedback sent by the receiving end, the server can determine that the data loss countermeasure of the current sensitive data is slightly not allowed to be lost according to the data loss countermeasure strategy stored in the server, and correspondingly, the memory block is triggered to resend the message data to the receiving end. When the message data is retransmitted, the message data can be transmitted to the receiving end through the fast transmission path or the slow transmission path. If the fast transmission path needs to be retransmitted to the receiving end, the message data specified by the receiving end is directly acquired from the memory block on the server, and the specified message data is sent to the receiving end. When the receiving end sends the data loss feedback to the server, the data loss feedback comprises the serial number of the lost message data, so that the server can know which message data which should be acquired from the memory block to be retransmitted to the receiving end. The receiving end sends heartbeat data to the server regularly, and the server maintains a data loss coping strategy.
In this embodiment, before receiving the first data loss feedback, the server sends a data loss handling policy to the server in advance after receiving the first piece of message data sent by the sending end, so that when receiving the data loss feedback sent by the receiving end, the server can resend the corresponding message data based on the data loss handling policy.
In one embodiment, the method further comprises: and when receiving the data loss feedback sent by the receiving end, cleaning or reserving the message data based on the occupation condition of the memory in the memory block.
The memory block is a space for calculation and storage, and the storage capacity of the memory block is relatively limited. The occupation condition of the memory in the memory block is the consumption condition of the storage space of the memory block. When the memory block stores the message data, the server does not intelligently identify and store the message data according to the type, the importance and the like of the message data, so that the message data stored in the memory block comprises sensitive data, non-sensitive data and other data.
Specifically, when the server receives the data loss feedback sent by the receiving end, it is known that the receiving end considers that the lost message data is sensitive data, after the data loss feedback is retransmitted to the receiving end, according to the use condition of the memory block, when the memory margin of the memory block is lower than the preset margin, the server will clear the part of sensitive data, and when the memory margin of the memory block is not lower than the preset margin, the server does not need to clear but can select to clear the part of sensitive data, that is, the server can retain the sensitive data.
In this embodiment, sensitive data in the memory block is adaptively cleaned or retained based on the occupation of the memory in the memory block, so that the memory block is ensured to maintain sufficient memory margin to store subsequent sensitive data.
In one embodiment, the method further comprises: if the message data is non-sensitive data, determining that the data loss coping strategy is allowed data loss; and continuously sending new message data to the receiving end based on the strategy of allowing the data loss.
In particular, if the message data is non-sensitive data, that is, the receiving end allows the loss of the message data, the requirement for reliable delivery is low. The receiving end sends a data loss signal to the server, the data loss signal comprises a mark of non-sensitive data, and when the server receives the data loss signal, the server can determine that the message data lost by the receiving end is the non-sensitive data according to the mark, so that the matched data loss coping strategy is allowed data loss. Based on the policy allowing data loss, the server will not obtain corresponding message data from the memory block or the disk and retransmit the message data to the receiving end, but the server continues to forward new message data sent by the sending end in real time to the receiving end.
In this embodiment, when the received message data is non-sensitive data, the receiving end determines that the data loss handling policy is a policy that allows data loss, and based on the policy, continues to send new message data to the receiving end, so that the server selects a situation when retransmitting the message data, and meets various requirements of the receiving end for obtaining the message data.
In one embodiment, when the message data is sensitive data and data loss feedback sent by the receiving end is received, the method further includes:
searching the message data from a disk; and retransmitting the message data to the receiving end.
In this case, the disk stores message data of all histories, and thus stores much message data compared to the message data stored in the memory block. The slow transmission path refers to a path in which the server retrieves the message data from the disk, and in this manner, since the lost message data is searched from a large amount of historical message data, the searching efficiency is relatively low, and thus the slow transmission path is provided. When the message data is non-real-time data in the sensitive data, the message data can be retransmitted through the slow transmission path. Meanwhile, if the fast path cannot guarantee that the message data is not lost, the message data can be transmitted according to the low-speed transmission path. In one embodiment, before the disk searching for the message data, the method further includes: and creating an index based on the number of the message data, and calculating the address of the message data in the disk according to the number of the message data. And indexing according to the serial number of the message data, so that the message data in the disk can be directly read. In addition, data recovery capability can be improved when application software or a server fails.
In this embodiment, when the message data is sensitive data and the data loss feedback is received, the server may further search the message data from the disk and resend the message data to the receiving end, so that when the storage space of the memory block is not cleared in time, the message data can be compensated by this way, and an alternative way is provided for the server to resend the data to the receiving end or on the transmission path.
