The client terminal 110 may perform a data transmission operation with different processing speeds according to various conditions such as network speed, performance of a computing device, memory capacity, and type of network adapter. The topology processing unit 310 may group by collectively considering the transmission capability and processing capability of each terminal, and may connect the relay groups generated as a result of the grouping to generate a network topology for data transmission.

Here, a topology refers to a physical connection of elements of a computer network, and may be defined as indicating a corresponding connection method or connection result. The topology processing unit 310 may define a plurality of relay groups for a plurality of client terminals 110 connectable through a network and utilize them in a data transmission process.

In an embodiment, the topology processing unit 310 configures a client cluster by classifying the plurality of client terminals 110 based on the data transmission processing speed, and selects at least one client member so as not to be concentrated on a specific client cluster. . Meanwhile, various parameters may be used in the grouping process of the client terminals 110 performed by the topology processing unit 310 .

For example, the leader determiner 330 may determine the client member having the best performance as the leader after sorting the client members based on the relay data processing performance.

In one embodiment, the leader determining unit 330 selects, as a leader, a client member capable of minimizing the processing delay of the master buffer based on the network transmission speed, CPU processing speed, memory processing speed, and buffer amount in the corresponding relay group. can do. Here, the master buffer is a buffer space allocated and defined on the internal memory of the client terminal 110 determined as a leader in the corresponding relay group, and may correspond to a specific memory area.

That is, the leader determiner 330 may determine, as a leader, the client terminal 110 that can provide the most optimal performance in the relay group in consideration of various parameters that may affect relay data processing performance. In particular, the client terminal 110 determined as the leader may provide a memory space for the master buffer, and may reduce the processing delay by minimizing the waiting time for data in the corresponding master buffer. Meanwhile, parameters that may affect the processing delay in the buffer may include a network transmission speed, a CPU processing speed, a memory processing speed, an average buffer amount, and the like.

The work thread processing unit 350 may generate a work thread that is proportional to the number of a plurality of relay groups and manages a master buffer set based on the relay data processing performance of the corresponding reader. That is, a work thread may be created corresponding to a plurality of relay groups, and may process a management operation related to the master buffer. The work thread may be created by the work thread processing unit 350 and may be assigned to a specific relay group to operate. At this time, in the case of a work thread assigned to a specific relay group, it can operate by utilizing the resources of the client terminals 110 existing in the group, and the work thread processing unit 350 is a relay group for allocating and executing a specific work thread. and the client terminal 110 can be determined, respectively, and commands related to their operation can be controlled integrally.

In an embodiment, the working thread processing unit 350 may generate a working thread to form a one-to-one relationship with each of the plurality of relay groups, and determine the size of the master buffer based on relay data processing performance. The work thread is for managing the master buffer, and when there is one master buffer in each relay group, it can be created in one-to-one correspondence with each relay group. In addition, the work thread processing unit 350 may set the size of the master buffer together according to the relay data processing performance of the relay group to which the corresponding work thread is to be allocated in the process of creating the work thread. That is, the working thread may be created including information about the corresponding relay group and information about the size of the master buffer, and when assigned to the relay group, the master buffer is sent to the client terminal 110 corresponding to the leader of the relay group. You can pass information about the size.

The data transmission processing unit 370 may transmit a file image to a specific relay group according to a data transmission order for file-related data transmission, and the file image is transmitted to a leader terminal of the corresponding relay group, and the corresponding relay group by the reader A relay operation within can be handled.

In an embodiment, the data transmission processing unit 370 may control the relay speed of the file image by variably setting the threshold buffer amount and the buffer waiting time of the slave buffer based on the buffer status information about the slave buffer. More specifically, the data transmission processing unit 370 may integrally receive buffer state information through the leader of the relay group, and perform dynamic control on the slave buffer of the corresponding relay group based on this. That is, the size of the slave buffer can be adjusted through the threshold buffer amount, and when a plurality of slave buffers are set, the buffer waiting time for each slave buffer can be set for each slave buffer.

For example, when a relay operation is initiated for a specific slave buffer, relay data can be delivered and stored in the corresponding slave buffer. It can wait until space is secured in the corresponding slave buffer. After that, when the buffer waiting time is exceeded, the process of reallocating the relay data to another slave buffer may be repeatedly performed, and the data transmission processing unit 370 controls the relay speed through relay order adjustment as well as the threshold buffer amount and buffer The relay speed can also be controlled by adjusting the waiting time.

In one embodiment, the data transmission processing unit 370 is buffer status information, based on the buffer size, the average buffer usage rate, the size ratio between the master buffer and the slave buffer, the total number of slave buffers, and the current available number of each slave buffer threshold buffer The amount and buffer waiting time can be set variably. In another embodiment, the data transmission processing unit 370 may variably set the threshold buffer amount of each slave buffer through the following equation.

[Equation]

Here, W may correspond to a critical buffer amount, k is a proportionality coefficient, S is a buffer size, U is an average buffer usage rate, Sm is a size of a master buffer, and Ss is a size of a slave buffer. Meanwhile, the data transmission processing unit 370 may standardize the threshold buffer amount by applying a ratio between the total number of slave buffers and the currently available number to the value derived through the above equation along with a proportional coefficient.

In one embodiment, the data transmission processing unit 370 detects that the limit of the threshold buffer amount is reached, and when the margin of the threshold buffer amount is reduced to the first reference, increases the buffer waiting time, and the margin of the threshold buffer amount is the second If it is increased to the standard, it is possible to reduce the buffer latency. The data transmission processing unit 370 dynamically adjusts the buffer waiting time in a step before the threshold buffer amount of the slave buffer reaches the limit, so that the relay speed can be flexibly controlled even if there is no adjustment of the relay order.

That is, when the margin of the threshold buffer amount is reduced to the first criterion, the capacity for relay data added thereafter may be reduced, and the relay speed may be reduced due to reallocation of relay data in the corresponding relay group. Accordingly, the data transmission processing unit 370 may adjust the relay speed by dynamically changing the buffer waiting time according to the degree of change regarding the margin of the threshold buffer amount. Meanwhile, the second criterion may be set higher than the first criterion, and the first and second criteria may be previously set and utilized by the cyber remote management device 130 .

The control unit 390 controls the overall operation of the cyber remote management device 130 , and controls flow or data between the topology processing unit 310 , the leader determination unit 330 , the work thread processing unit 350 , and the data transmission processing unit 370 . You can manage the flow.
