In this embodiment, the data transmission channel 221 is specifically a TCP transmission channel, and the transmission control module 12 is provided with a TCP monitoring port.
The system is applied to practice, and a specific work flow is shown in fig. 2, and comprises the following steps:
s1, a plurality of clients respectively create corresponding data transmission tasks and sequence the data transmission tasks according to the sequence of creation time;
s2, the plurality of clients respectively establish data transmission channels corresponding to respective data transmission tasks, in the embodiment, the plurality of clients specifically establish the data transmission channels corresponding to the respective data transmission tasks by respective data transmission modules in a TCP connection mode;
s3, according to the sequence of the data transmission tasks, the transmission control module correspondingly distributes and connects the data transmission channels sequenced into the first N data transmission tasks to each flash memory area in the data storage module, so that one flash memory area is independently connected with one data transmission channel, and the data transmission channels of the rest data transmission tasks are simultaneously connected to the shared memory area in the data storage module, wherein N =5 in the embodiment;
s4, the transmission control module respectively controls a plurality of data transmission channels correspondingly connected with the fast memory area to simultaneously transmit data, and controls a plurality of data transmission channels connected with the shared memory area to transmit data in a grouped time interval mode, wherein when the data transmission channels transmit data, the data reading module of the client side to which the data transmission channels belong respectively acquires the data to be transmitted from the database of each client side and transmits the data to be transmitted to the corresponding data transmission channels;
when controlling data transmission of the shared memory area, the transmission control module firstly groups a plurality of data transmission channels connected with the shared memory area according to a data transmission task sequence, and then the transmission control module controls each group to circularly transmit data according to the grouping sequence and preset data transmission time, in the embodiment, the number of the data transmission channels contained in each group is less than or equal to 5, and the preset data transmission time is 10s;
and S5, monitoring the data traffic of the data transmission channels correspondingly connected with the fast memory areas by the transmission control module, and if the data traffic of one data transmission channel is monitored to be 0, releasing the fast memory area connected with the data transmission channel to distribute and connect to the data transmission channel with the highest sequencing in the shared memory area until all the data transmission channels complete respective data transmission tasks.
In this embodiment, when the method is applied specifically, the memory resources of the backup storage unit are first divided into two types: the fast memory and the shared memory are configured to be 5 fast memory areas and 1 shared memory area when the system is started and initialized, as shown in fig. 3 and 4, where the fast memory area is an independent memory pool, the memory pool is responsible for allocating memory resources to the data transmission channel to store data to be processed received from the data source, and the memory pool can only be exclusively occupied by one transmission channel, the shared memory area is also an independent memory pool, the memory pool is responsible for allocating memory resources to the data transmission channel to store data to be processed received from the data source, and unlike the fast memory area, the shared memory area can be commonly used by a plurality of transmission channels. When a large number of concurrent tasks start to perform data transmission, each task establishes a data transmission channel, where the data transmission channel is a network channel established between a data source and a backup storage unit, and for example, a TCP connection is a data transmission channel.
For the data transmission channels (channel 1-channel 5 in the figure) started by the first 5 tasks, each channel is allocated to a fast memory area, and the transmission channels exclusively occupy the memory area. The data transmission channels (channel 6-channel 10 in the figure) for starting the subsequent tasks are commonly allocated to the shared memory area. When the data transmission channel (channel 1 in the figure) allocated to the flash memory area finishes data transmission, the flash memory area is immediately released and allocated to one data transmission channel (channel 6 in the figure) in the shared memory area, so that the transmission channel continues to be exclusively used until the data transmission is finished. The purpose of dividing the fast memory area and the shared memory area is that the fast memory area is monopolized by a single data transmission channel, is not influenced by the occupation of resources of the shared memory area, can fully utilize the system bandwidth, and achieves the effect of high-efficiency data transmission.
Secondly, for the data transmission channels of the shared memory area, there is a risk that the task cannot be continued due to resource preemption, so for the shared memory area, the time resource used by the shared memory area is divided into segments, for example, each segment of time is divided into 10 seconds, all the data transmission channels are divided into 5 groups, each group is assigned with a group number, after the transmission starts, the group number currently processed is recorded, within one 10 seconds, only one group of data transmission channels is allowed to work, after the use time of the 10 seconds is finished, the group number currently processed is updated to be the next group, the data transmission of the next group of channels is continued, and after the last group is reached, the channels are switched to the first group of channels again for data transmission. The purpose of dividing the service time into segments is to avoid the situation of seizing a large number of resources in a short time, ensure that each data transmission channel has an opportunity to transmit data, ensure fairness, avoid the situation of task locking and achieve the effect of smooth data transmission.
Through two resource division and scheduling algorithm modes, the data transmission control under the multi-task concurrent scene can be efficiently and smoothly carried out.
In order to verify the high efficiency and the fluency of data transmission in the multitask concurrency scenario, in another embodiment, 100 service hosts of different data sources are prepared, a backup client is installed on a service host system, and a backup console is installed on another host. The client comprises a data reading module and a data transmission module. The console comprises a data storage module and a data transmission control module, and mainly provides functions of storage management, data transmission control in a concurrent scene and the like. The console needs to provide a TCP monitoring port, and the client connects to the port of the console to establish a data transmission channel.
Then, carrying out concurrent data transmission control test:
1. data transmission task creation process: and selecting each client connected to the console as a backup object, creating a task based on the client host, and backing up the data of the volume D on the client host, wherein the data volume of each client host is consistent in size.
2. Data transmission task initiating stage: and sequentially initiating the first 5 backup tasks created in the previous step, wherein each task establishes a data transmission channel to the console and prepares to start data transmission.
3. And a concurrent data transmission control stage: after the first 5 tasks are initiated, the transmission control module allocates an independent fast memory area to each task, and it can be seen by observing TCP flow that the 5 tasks can achieve a very high transmission rate.
4. A data transmission task initiation stage: the remaining 95 backup tasks are initiated in sequence, each task establishing a data transmission channel to the console and preparing to begin data transmission.
5. And a concurrent data transmission control stage: and the transmission control module distributes a shared memory area to each task and triggers the shared memory areas to be used in a segmented manner, and by observing the TCP transmission flow of the tasks, each group of tasks can obtain data transmission every 10 seconds, and the phenomenon that the data transmission is not carried out all the time can be avoided.
6. And a concurrent data transmission control stage: after a period of time, one of the first 5 created tasks is finished transmitting, and it can be observed that the transmission rate of one of the later initiated tasks is obviously increased, indicating that one of the later initiated tasks is reallocated to the flash memory area for data transmission.
7. And a data transmission ending stage: continuing with the observation, it can be seen that the remaining 99 tasks can end the data transfer in turn.
In summary, the present invention avoids the problem of serious resource competition in multiple concurrent scenarios through resource partitioning and scheduling algorithms, and can ensure both high efficiency and smoothness of data transmission through the method of fast memory partition, shared memory partition grouping and using time segmentation.
