In order to better describe the data transmission method, system, node and readable storage medium of the embodiments of the present invention, a working system is proposed herein, as shown in fig. 1, where the working system includes a first machine room and a second machine room, the first machine room deploys a control module, a configuration library, a data cache module, a data receiving module and an encryption module, the configuration library is used for storing configuration information, and the second machine room deploys a decryption module, a data output module and a data storage module; after an administrator issues a configuration instruction to a first machine room through the Web (World Wide Web), the data receiving module can acquire configuration information corresponding to the configuration instruction and complete initialization configuration, and then the first machine room can complete caching, encryption and forwarding of data to be forwarded according to the configuration information and forward the data to a second machine room. After receiving the data received by the first machine room, the second machine room receives, decrypts and stores the data in the data storage module.
It should be noted that, the working system provided in the embodiment is for more clearly describing the technical solution of the embodiment of the present invention, and does not limit the technical solution provided in the embodiment of the present invention.
Referring to fig. 2, fig. 2 is a flowchart of a data transmission method according to an embodiment of the present invention, including but not limited to steps S100 to S300,
step S100, obtaining data to be forwarded according to service limitation preset time;
step S200, the data length of the data to be forwarded is adjusted according to the preset value of the bandwidth speed limit, and the data to be forwarded is obtained;
step S300, the forwarding data is sent to the next node.
The service limit preset time represents the time when the data to be forwarded is not allowed to be sent, in the time period, the data receiving module can stop reading the data to be forwarded from the data caching module so as to ensure that normal business is not impacted as much as possible, and the data to be forwarded can be read only in the time period corresponding to the time exceeding the service limit preset time, and the data is forwarded.
In the process of forwarding data, the influence of occupied network bandwidth on normal service is further considered, so that the transmission rate of data transmitted by the data receiving module is restrained by utilizing the bandwidth speed limit preset value, and the data quantity transmitted each time is within the restraint range of the bandwidth speed limit preset value. And when the data quantity of the data to be forwarded read each time exceeds the target length, the data length is adjusted to the range of the constraint of the bandwidth speed limit preset value, so that the loss of the data can be avoided, and the situation that excessive bandwidth is occupied during data transmission can be ensured. Finally, after the service limiting preset time and the bandwidth limiting preset value are subjected to double limiting and adjusting, the forwarding data read from the data caching module can be transmitted to the next node (for example, the second machine room).
According to the data transmission method, the preset service limiting time is set, so that the current node does not perform data transmission in the peak time of normal service handling, occupation of the off-site broadband in the normal service handling time is effectively reduced, meanwhile, the preset bandwidth limiting value occupied by data transmission is further limited when off-site data transmission is performed, the problem that the bandwidth is fully occupied due to short-time data surge in off-site data transmission is avoided, and interference to normal service handling is further relieved.
In some embodiments, step S100 includes, but is not limited to, the following steps:
and stopping acquiring the data to be forwarded from the data caching module if the current time is within the service limit preset time, wherein the data caching module is used for caching the data to be forwarded sent by the previous node.
And in a practical section corresponding to the service limiting preset time, the data receiving module can stop reading the data to be forwarded from the data caching module, and further can stop the next node to send the data to be forwarded. At this time, the previous node (for example, other service systems or a higher data center) may continue to send data to be forwarded to the first machine room, and then the data to be forwarded are stored in the data buffer module of the first machine room in a queue according to a time sequence, and after exceeding the service limit for a preset time, the data to be forwarded are read and then sent.
In some embodiments, step S100 further comprises the steps of:
and if the current time is not in the service limiting preset time, acquiring data to be forwarded from a data caching module, wherein the data caching module is used for caching the data to be forwarded sent by the previous node.
When the time period corresponding to the service limit preset time is exceeded, the data receiving module reads the data to be forwarded according to the time sequence of the data to be forwarded cached in the data caching module and then transmits the data to the next node; it should be noted that, in the forwarding process, if data is sent to the first machine room, the data is stored at the last end of the cached data queue in the data caching module, and the data is sent continuously according to the time sequence after the backlogged data to be forwarded is sent.
In some embodiments, step S200 includes, but is not limited to, the steps of:
if the data length of the currently read data to be forwarded exceeds the bandwidth speed limit preset value, discarding the currently read data to be forwarded, and re-reading the data length to be smaller than the data length of the currently read data to be forwarded until the data length of the re-read data to be forwarded is smaller than or equal to the bandwidth speed limit preset value, thereby obtaining the data to be forwarded.
When data is read, in order to ensure the completeness of the data, the data can be read one by one, therefore, when the data is read, the approximate number M can be estimated according to the configuration, but after the M data is read, the bandwidth required by single data transmission is likely to exceed the preset bandwidth limiting value, at the moment, in order to avoid overspeed, the M data read before is discarded in order to ensure the integrity of data transmission, then the M-1 data is read again, whether the preset bandwidth limiting value is exceeded is judged, if so, the number of the data read is further reduced until the finally read data to be forwarded is within the constraint range of the preset bandwidth limiting value, and finally the finally read data is transmitted as the current data. It should be noted that, the data in the data buffer module may not be discarded in the reading stage, but may be discarded or covered after the current forwarding data is sent, so as to ensure the integrity of the final transmission data.
In some embodiments, step S200 further comprises the steps of:
and if the data length of the currently read data to be forwarded is smaller than or equal to the preset bandwidth speed limit value, taking the data to be forwarded as the current forwarding data.
When the data length of the data to be forwarded read by the data receiving module does not exceed the preset bandwidth speed limit value, the data transmission is indicated to not exceed the constraint range of the preset bandwidth speed limit value, and therefore the read data to be forwarded is directly sent.
In some embodiments, the data transmission method further comprises:
and encrypting the data to be forwarded.
For the security of data transmission, encryption processing is performed first during data transmission to prevent non-relevant personnel or institutions from stealing business materials. The data to be forwarded, read by the data receiving module, is encrypted by the encryption module and then transmitted to the second computer room, and the second computer room is decrypted by the decryption module and then transmitted to the data storage module. It should be noted that, because the encryption of the data is required, and the data length of the data is changed during encryption, in order to ensure that the constraint requirement of the bandwidth speed limit preset value is not exceeded in the data transmission process, the data receiving module firstly encrypts the data after reading the data to be forwarded, and then judges whether the data length of the data exceeds the constraint of the bandwidth speed limit preset value.
In some embodiments, the encryption process may be directly performed using the 3DES reversible algorithm, or may be performed using other existing encryption algorithms.
As shown in fig. 3, in some embodiments, the data transmission method further includes step S400,
step S400, obtaining configuration information, wherein the configuration information comprises service limit preset time and a wide speed limit preset value.
Before data is received and transmitted, in order to ensure that the transmitted data can receive time and bandwidth constraints, configuration information is acquired in advance, and after the configuration information is acquired, initialization configuration is completed.
For better illustrating the data transmission method according to the embodiments of the present application, a specific embodiment is further described herein. In this embodiment, the service limit preset time is 8:00 to 18:00, the bandwidth limit preset value is 1M/S, and the encryption algorithm is a 3DES reversible algorithm.
An administrator issues a configuration instruction to a configuration library on a WEB interface, and a data receiving module reads configuration information (at least comprising service limit preset time and bandwidth limit preset value) corresponding to the configuration instruction and completes initialization setting;
the data receiving module continuously receives data to be forwarded transmitted by an external system and stores the data in the data caching module;
if the current time is 8:00 to 18:00, continuously caching the received data to be forwarded and a data caching module;
if the current time is not 8:00 to 18:00, starting a thread, reading data to be forwarded from a data caching module, reading M pieces of data according to configuration information for the first time, and encrypting the read M pieces of data by using a 3DES reversible algorithm to obtain encrypted data to be forwarded; judging whether the data length of the encrypted data to be forwarded exceeds 1M, if so, discarding the read data, re-reading M-1 pieces of data, and then re-judging whether the data length of the read data to be forwarded is less than 1M until the data length of the read data to be forwarded after encryption processing is less than 1M, wherein the data to be forwarded is used as the data to be forwarded; in addition, when the length of the data after the encryption of the M pieces of data read for the first time is less than 1M, the data can be directly used as the current forwarding data;
and forwarding the forwarded data to a decryption module in the second machine room, completing decryption work, and sending the decrypted data to a data storage module for storage.
According to the data transmission method of the embodiment, the preset time for limiting the service is set, so that the current node cannot conduct data transmission in the peak time of normal service handling, occupation of the off-site broadband in the normal service handling time is effectively reduced, meanwhile, when off-site data transmission is conducted, the preset value for limiting the bandwidth speed occupied by the data transmission is further limited, and therefore the problem that the bandwidth is fully occupied due to short-time data surge in off-site data transmission is avoided, and interference to normal service handling is further relieved.
An embodiment of the present invention also provides a data transmission system including: a data receiving unit, a data reading unit and a data transmitting unit,
the data receiving unit is used for acquiring data to be forwarded according to the service limit preset time;
the data reading unit is used for adjusting the data length of the data to be forwarded according to the bandwidth speed limit preset value to obtain the data forwarded at this time;
and the data transmitting unit is used for transmitting the forwarding data of the time to the next node.
The service limiting preset time represents the time when the data to be forwarded is not allowed to be sent, in the time period, the data receiving unit can stop reading the data to be forwarded from the data caching module so as to ensure that normal business is not impacted as much as possible, and the data to be forwarded can be read only in the time period corresponding to the time exceeding the service limiting preset time, and the data is forwarded.
In the process of forwarding data, the influence of occupied network bandwidth on normal service is further considered, so that the transmission rate of data transmitted by the data receiving module is restrained by utilizing the bandwidth speed limit preset value, and the data quantity transmitted each time is within the restraint range of the bandwidth speed limit preset value. And when the data quantity of the data to be forwarded read by the data reading unit each time exceeds the target length, the data length is adjusted to the range of the constraint of the bandwidth speed limit preset value, so that the loss of the data can be avoided, and the situation that excessive bandwidth is occupied during data transmission can be ensured. Finally, after the service limiting preset time and the bandwidth limiting preset value are subjected to double limiting and adjustment, the forwarding data read from the data caching module can be transmitted to the next node (for example, the second machine room) through the data sending unit.
The data transmission system of the embodiment of the invention ensures that the current node does not carry out data transmission in the peak time of normal service handling by setting the service limiting preset time, thereby effectively reducing the occupation of the off-site broadband in the normal service handling time, and simultaneously, further limiting the bandwidth limiting preset value occupied by the data transmission when carrying out off-site data transmission, thereby avoiding the problem that the off-site data transmission is fully occupied by the bandwidth due to short-time data surge and further relieving the interference on the normal service handling.
