For better illustration of the following embodiments, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the actual product dimensions; it will be appreciated by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted.
Examples
As shown in fig. 1, this embodiment provides a data processing method based on edge cloud, including:
s10, receiving operation data transmitted by a central cloud;
as shown in fig. 2, in this embodiment, the center cloud is communicatively connected to the edge cloud, and the edge cloud is communicatively connected to the terminal server. The center cloud transmits the operation data to the edge cloud, and the edge cloud processes the operation data and provides the operation data to the terminal server. The job data is a computer instruction, and the edge cloud is used for executing the job data to provide forwarding, storage and computing services for users. The center cloud comprises an internet data center and the edge cloud comprises a domain controller. The domain controller comprises a domain name resolver and a domain name server, and the Internet data center is respectively in communication connection with the domain name resolver and the domain name server. The terminal server is respectively in communication connection with the domain name resolver and the domain name server.
The edge cloud also includes DNS and dynamic DNS. The DNS is respectively in communication connection with the domain name resolver and the domain name server, and analyzes the domain name resolver and the domain name server. The dynamic DNS is in communication connection with the domain name resolver and the domain name server, and analyzes the domain name resolver and the domain name server.
The operation data sent by the user passes through the Internet data center, and at the moment, the center cloud performs preliminary cloud computing on the operation data. After the center cloud performs simple calculation on the operation data, the operation data passes through the domain controller, at the moment, the domain name resolver and the domain name server in the domain controller analyze the access IP address by utilizing the DNS and the dynamic DNS, so that further processing of the transmission data by the terminal server is realized, when the operation data is primarily processed by the Internet data center, the city backbone network is adopted for domestic data, the wide area network is adopted for data transmission for foreign data, and reasonable interval division is performed on the data transmission interval, so that the effect that the data transmission rate of the edge cloud is accelerated in the operation data processing process is realized.

Judging whether the data is legal or not, and judging the legitimacy of the data and the legitimacy of the data transmission process in batches. Data types include, but are not limited to, photographs, text, and numbers. The existing judging mode is to compare the photo, the text and the number with the data stored in the edge cloud so as to distinguish illegal data. If the edge cloud uses the existing judging mode, comparing and identifying the non-uniform format data such as photos, characters, numbers and the like one by one, the operation of identifying can occupy a large amount of computing resources, and the edge cloud server cannot process massive comparison data in time. To this end, the present invention employs an exponential smoothing algorithm to solve this problem.
As a further aspect of the present invention, the performing validity verification on the job data includes:
performing data validity verification on the operation data based on an exponential smoothing algorithm;

and if the operation data passes the transmission validity verification, judging that the operation data passes the validity verification.
In the process of validity verification, for the situation that the operation data is legal but the operation data transmission process is illegal, the edge cloud returns the operation data to the user of data transmission, and the operation data is re-transmitted until the data transmission process is that the operation data is transmitted through a legal channel, the successful data transmission is displayed, and the situation that the vulnerability propagation in the data transmission is not beneficial to practical development by using an lawless person is effectively avoided. And recording and storing transmission sources and modes of the illegal operation data so as to inquire the photo, the characters and the numbers at any time, eliminate the illegal data, prevent the secondary propagation of the illegal data and further strengthen the security of data propagation.
As a further aspect of the present invention, the data validity verification is performed on the job data based on an exponential smoothing algorithm, including the steps of:
establishing a detection model based on an exponential smoothing algorithm; and setting rule data; the rule data is data conforming to a legal rule;
the exponential smoothing algorithm is a medium-short term time sequence data trend prediction algorithm which is compatible with the length of a full-term average and a moving average, and is characterized in that the past observations are given different weights, namely the weights of the more recent observations are larger than the weights of the long-term observations. According to different smoothing times, the exponential smoothing algorithm is divided into a primary exponential smoothing method, a secondary exponential smoothing method, a tertiary exponential smoothing method and the like. The basic ideas of the exponential smoothing algorithm are: the predicted value is a weighted sum of previous observations and different weights are given to different data, with new data given a larger weight and old data given a smaller weight.
The formula of the exponential smoothing algorithm is as follows:
Y t+1 ＝αX t +α(1-α)X t-1 +α(1-α) 2 X t-2 +…+α(1-α) n X t-n (1.1)
wherein Y is t+1 For the predicted value of the operation/rule data, alpha is a weight coefficient, n is a smooth index, t is the observation period number of the operation/rule data, and X is the observation value of the operation/rule data.
The exponential smoothing value in any period is the weighted average of the actual observed value in the present period and the exponential smoothing value in the previous period, the formula (1.1) is deduced, and the exponential smoothing value is smoothed again on the basis of primary exponential smoothing to obtain a secondary exponential smoothing formula:
in the formulae (1.2) and (1.3),for the first smoothed value of phase t, +.>Is the second smoothed value of the t-th stage, X t For the t-th-period job/rule observation, t=1, 2,3, …, n (n is the number of raw data).
The parameters of the above secondary exponential smoothing formula include:
calculating the job data and the rule data by using the detection model;
as a preferable mode of the present embodiment, job data of different formats, i.e., photographs, letters, numerals, etc., inputted into the detection model are converted into binary numbers to be sequentially developed. The expanded job data is then partitioned and arranged, and each segment is marked according to a time sequence. Setting the observation period number of the expanded operation data as t, and setting the observation value of each observation period of the operation data as X t 、X t-1 、X t-2 …、X t-n . Data outside the observed values are ignored, thereby reducing the amount of data that needs to be compared. And carrying out unequal right processing according with actual conditions on the data at different times, and dividing the data into different smoothing grades according to the smoothing times. Substituting the operation data observation value and the operation data observation period number into a detection model established based on an exponential smoothing algorithm, and calculatingTo obtain the corresponding secondary exponential smoothing parameter alpha t And b t 。
And similarly, converting the rule data into binary system, sequentially expanding, dividing and arranging the expanded rule data, and marking each segment according to the time sequence. Setting the observation period number of the expanded rule data to t (consistent with the observation period number of the job data), and setting the observation value of each observation period of the rule data to P t 、P t-1 、P t-2 …、P t-n . Data outside the observed values are ignored, thereby reducing the amount of data that needs to be compared. And carrying out unequal right processing according with actual conditions on the data at different times, and dividing the data into different smoothing grades according to the smoothing times. Substituting the rule data observation value and the rule data observation period number into a detection model established based on an exponential smoothing algorithm to calculate a corresponding secondary exponential smoothing parameter Qalpha t And Qb t 。
And comparing the calculation results of the job data and the rule data, thereby verifying the data validity of the job data.
Respectively the parameter alpha t Sum parameter qα t Parameter b t Sum parameter Qb t Comparison was performed. If the parameter alpha t Sum parameter qα t Consistent, and parameter b t Sum parameter Qb t And if the operation data of the part corresponding to the proving parameter is identical to the rule data and accords with the legal rule, judging that the part of operation data passes the data legal verification. If the parameter alpha t Sum parameter qα t Inconsistencies, or/and parameters b t Sum parameter Qb t And if the operation data of the corresponding part of the parameters are inconsistent with the rule data and do not accord with the legal rule, judging that the operation data of the part does not pass the data legal verification.
As a preferable scheme of the embodiment, the front part and the middle part or the middle part and the last part of the expanded operation data/rule data can be extracted for calculation comparison of the observation value extracted by the operation data/rule data, the length of the data is not required to be considered, and the observation period t of the operation data and the rule data is only required to be consistent. And comparing the operation data with a plurality of parameters of the rule data for a plurality of times, and judging that the whole operation data passes the verification of data validity as long as 80% of comparison results are consistent.
S30, if the operation data do not pass the validity verification, the operation data transmitted by the center cloud are received again;
s40, if the operation data passes the validity verification, analyzing the operation data, and calculating the data quantity and the expected transmission time of the operation data;
specifically, analysis of the job data obtains the type, the substantial content and the resource requirement of the job data. According to the type, the substantial content and the resource requirement of the data operation, the operation data are deployed to the corresponding virtual machine for execution, so that the execution efficiency is improved, the data quantity and the expected transmission time of the operation data are calculated, parameters are provided for subsequent port regulation and delay transmission, the phenomenon that the data transmission is invalid and the data transmission cannot be completed in time is effectively prevented. For example: and setting the expected transmission time to be 10S for the 20MB job data, and considering that the transmission fails if the expected transmission time exceeds the expected transmission time, and delaying the secondary transmission of the job data by the edge cloud after the transmission failure to prevent the data transmission failure.
S50, eliminating redundancy of the operation data according to the analysis result of the operation data;
specifically, the edge cloud analyzes the essential content from the job data, and the error and repeated parts of the essential content are removed, so that the time for data processing is effectively shortened. For example: and (3) analyzing and calculating a plurality of groups of repeated photos appearing in the transmission data to reserve the photos meeting the transmission requirement, and automatically rejecting the photos acquired by illegal ways in the transmission process.
S60, compressing and decomposing the operation data with redundant elimination, and regulating and controlling the decomposed operation data to corresponding ports according to the data quantity and the expected transmission time of the operation data;
specifically, the method and the device have the advantages that the decomposed operation data are reasonably regulated and controlled, the operation data are scheduled to idle/proper ports for transmission, the phenomenon of data congestion in the transmission process of the operation data can be reduced, and the circulation of the data is facilitated. For example: the operation data has 6 parts, three ports are reasonably distributed, and the output port starts to transmit the next part of data, so that the transmission efficiency is effectively improved. Also for example: and the decomposed operation data is transmitted by using the port with the idle edge cloud, so that the occupation of a transmission channel in the transmission process is reduced.
And S70, transmitting the job data positioned at the port to a terminal server.
Judging whether the terminal server receives the operation data;
if the terminal server does not receive the operation data within the expected transmission time, retransmitting the operation data to the terminal server;
and if the terminal server receives the job data within the expected transmission time, ending the job data transmission.
As a preferable scheme of the embodiment, in the process of transmitting the executed job data to the terminal server, the edge cloud monitors whether the terminal server receives the job data, so as to judge the validity of the data.
When the terminal server receives the job data, the edge cloud is effective to execute the data, and the job process is finished. The job data has been transmitted to the terminal server but has not been received beyond the expected transmission time, and the edge cloud sends an instruction to the output port that the job data has not been received. At this time, the output port starts to perform secondary transmission on the data stored by the edge cloud and transmitted in a delayed manner, so that the phenomenon that the data is lost in the transmission process is effectively prevented. In addition, the data transmitted in a delayed manner is automatically transmitted through the instruction, so that the problem that in the prior art, a data sender and a data receiver grasp the same data information is solved, and the data transmission in the edge cloud is facilitated. After the terminal server receives the operation data, the edge cloud receives a feedback instruction of the terminal server, eliminates the operation data which are transmitted in a delayed mode, and effectively prevents the edge cloud from generating data redundancy.
