In an embodiment of the present invention, the resource allocation module includes:
the numbering module is used for numbering the servers;
the system comprises a first data configuration module, a second data configuration module and a third data configuration module, wherein the first data configuration module is used for sequentially configuring original data for each server according to a server unallocated data principle in the first original data allocation process until all the servers perform resource configuration of the original data, and recording resource consumption values of the original data classified by each server;

The principle that the servers do not classify the data means that the original data are preferentially and sequentially distributed to the servers without the distributed data, and the servers distributed with the first original data do not distribute the second original data until all the servers are distributed with the first original data. The raw data obtained again from the communication device is then no longer the first raw data but a second raw data to be distributed.
Then, starting from the second time of original data allocation of each server by using an accumulative recording module, recording the accumulative resource consumption of all original data transmitted to each server in real time before resource allocation is carried out on the original data each time;

In an embodiment of the present invention, the channel configuration module includes:
the occupancy monitoring module is used for monitoring the channel occupancy of the channel where the server is located in real time;
the server control module is used for judging whether the channel occupation amount of the channel exceeds the occupation amount of the channel by a first threshold value; controlling a server corresponding to the channel to utilize a lightweight cryptographic algorithm to enable the channel quantity between a first threshold and a second threshold occupied by the channel corresponding to the server, generating a channel cipher text K by combining a security channel shared Key, and sending the channel cipher text K to a channel configuration module;

and the configuration module is used for controlling the resource configuration module to sequentially screen out the servers corresponding to the comparison result in the comparison result data set from large to small, sending the serial numbers corresponding to the servers to the channel configuration module, circularly starting the occupancy monitoring module, the server control module, the ciphertext monitoring module, the ciphertext generating module, the decoding module and the execution module in sequence until available channels are screened out, and then sending the serial numbers of the servers corresponding to the available channels to the data transmission module.
The working principle of the technical scheme is as follows: in the network data transmission process, one channel corresponds to a plurality of servers, and although one or a plurality of servers under a certain channel often have a large residual processing capacity, due to the large data processing amount of other servers under the channel, the occupied amount of the channel is large, the resources of the channel are not matched with the resources of the servers, and further, the network data processing efficiency and speed are reduced or network faults are caused at the channel due to improper resource allocation in the resource allocation process.
Therefore, in order to solve the problem, in the embodiment, firstly, the occupied channel amount of the channel where the server is located is monitored in real time by using the occupied channel amount monitoring module;

sending the channel ciphertext P to a server corresponding to the server code by using a decoding module, controlling the server to decode the channel ciphertext P by using a lightweight cryptographic algorithm, and obtaining a decoded message, wherein the decoded message comprises a resource consumption value of the original data;

And the resource configuration module is controlled by the configuration module to sequentially screen out servers corresponding to the comparison result in a comparison result data set from large to small, numbers corresponding to the servers are sent to the channel configuration module, the occupancy monitoring module, the server control module, the ciphertext monitoring module, the ciphertext generation module, the decoding module and the execution module are sequentially and circularly started until available channels are screened out, and then the numbers of the servers corresponding to the available channels are sent to the data transmission module.
The technical effect of the technical scheme is as follows: firstly, the control server encrypts the available residual channel quantity in the channel through a lightweight cryptographic algorithm to form a ciphertext and transmits the ciphertext to the channel configuration module, so that the channel quantity occupied by data transmission can be effectively reduced, meanwhile, the situation of data messy codes or errors in the data transmission process can be effectively prevented by encrypting the residual available channel quantity, and the accuracy of data transmission is improved. And then, a channel ciphertext P is generated by combining the decoding text k on the basis of a numerical value corresponding to the resource consumption value of the original data by using a lightweight cryptographic algorithm, so that the channel amount occupied by data transmission can be effectively reduced, and the accuracy of data transmission can be improved. In addition, the channel occupancy warning and the execution forbidding are separated by setting two hierarchical thresholds (namely, a first occupancy threshold and a second occupancy threshold, wherein the numerical value of the second occupancy threshold is greater than the numerical value of the first occupancy threshold) of the channel, so that the channel allocation has a warning function, the reasonable use of the channel is effectively improved, and the channel congestion can be effectively prevented by the channel matching method.

and 5, sending the original data to a corresponding server according to the configuration result obtained by the resource configuration module and the channel configuration module.
