Detailed Description
In order to make the objects, technical solutions and effects of the present invention clearer and more specific, the present invention will be described in further detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
The embodiment provides a breakpoint continuous transmission method based on an encryption protocol bandwidth, which can realize breakpoint continuous transmission when a data transmission process is interrupted, and ensure that a data receiving end can receive complete data. Specifically, the embodiment may first acquire a transmission state of a data transmission process, and record, when the transmission state is an abnormal state, abnormal time information, where the abnormal time information is used to reflect a time when the abnormal state occurs. Then, based on the abnormal time information, first data which is transmitted before the abnormal time information by the data transmission process is determined, and based on the transmitted first data, missing data is determined, wherein the missing data is data which is not transmitted yet. And finally, when the transmission state is a normal state, controlling the data transmission process to continue transmitting the missing data based on an encryption protocol bandwidth. The embodiment adopts the encryption protocol bandwidth, so that the abnormality of data transmission can be detected in real time, the encryption transmission of the data can be realized, and the data security is ensured.
The breakpoint continuous transmission method based on the encryption protocol bandwidth can be applied to a terminal, and the terminal can be an intelligent product terminal such as a computer and a mobile phone. As shown in fig. 1, the breakpoint continuous transmission method based on the encryption protocol bandwidth includes the following steps:
step S100, acquiring a transmission state of a data transmission process, and recording abnormal time information when the transmission state is an abnormal state, wherein the abnormal time information is used for reflecting the occurrence time of the abnormal state.
In this embodiment, there is at least one data transmitting end and one data receiving end, and the data transmitting end transmits data to the data receiving end. When data transmission is performed, the embodiment may implement obtaining a transmission state of a data transmission process, where the transmission state reflects whether the data transmission process is normal at the time, and if the transmission state is an abnormal state, the transmission state is interrupted at the time, and the terminal may record abnormal time information, where the abnormal time information is used to reflect a time when the abnormal state occurs, so as to implement breakpoint continuous transmission in a subsequent step.
In one implementation manner, when acquiring a transmission state of a data transmission process, the embodiment includes the following steps:
step S101, controlling the data transmission process to continuously transmit the first data based on the encryption protocol bandwidth, and encrypting the first data while transmitting the first data;
step S102, continuously monitoring whether a data receiving end receives the first data;
step S103, if the data receiving end receives the first data, determining that the transmission state is a normal state;
step S104, if the data receiving end does not receive the first data, determining that the transmission state is an abnormal state.
Specifically, the encryption protocol bandwidth of the embodiment includes user datagram protocol (UDP, user Datagram Protocol), and the UDP protocol provides a method for sending an encapsulated data packet without establishing a connection, so that the transmission speed is fast by fully utilizing the fast data packet sending performance of the UDP protocol, the next message can be transferred without the response of the receiver, and the network bandwidth can be used for file data transmission to the greatest extent. In addition, the encryption protocol bandwidth of the present embodiment further includes an encryption type reflecting an algorithm type for encrypting data at the time of data transmission, such as an MD5 encryption algorithm or a DES encryption algorithm. When data transmission is performed, the embodiment controls the data transmission process to continuously transmit first data based on the encryption protocol bandwidth, and performs encryption processing on the first data while transmitting the first data so as to ensure the safety of data transmission. If the data receiving end receives the first data, the transmission state of the data transmission process is a normal state, and if the data receiving end receives the first data, the data transmission is interrupted, so that the transmission state of the data transmission process can be determined to be an abnormal state. When it is determined that the transmission state is an abnormal state, the present embodiment may record abnormal time information reflecting the time at which the abnormal state occurs, that is, the time at which the interruption of the recording data occurs, so that the breakpoint resume is performed based on the abnormal time information in the subsequent step.
Step 200, determining first data transmitted by the data transmission process before the abnormal time information based on the abnormal time information, and determining missing data based on the transmitted first data, wherein the missing data is data which is not transmitted completely.
When the abnormal time information is obtained, the terminal of the present embodiment may determine, based on the abnormal time information, first data that has been transmitted by the data transmission process before the abnormal time information, that is, determine the amount of data that has been transmitted before the interruption of data transmission occurs. The terminal may then determine, based on the transmitted first data, that data not transmitted is found, i.e. missing data. The missing data in this embodiment is the data that needs to be transmitted in a breakpoint in the subsequent step, so as to ensure the integrity of the data.
In one implementation manner, the method specifically includes the following steps when acquiring missing data:
step S201, determining the transmission progress of the data transmission process based on the abnormal time information;
step S22, determining first data transmitted before the abnormal time information according to the transmission progress;
step 203, obtaining a target transmission amount corresponding to the data transmission process, where the target transmission amount is a transmission amount to be completed by the data transmission process;
step S204, determining missing data based on the target transmission quantity and the transmitted first data.
Specifically, the terminal is firstly based on a target transmission amount corresponding to a data transmission process, wherein the target transmission amount is the transmission amount to be completed by the data transmission process. The data transmission duration can be estimated based on the target transmission amount, and of course, the data transmission duration is affected by the broadband state. The data transmission duration of the embodiment is estimated based on the fact that the broadband state is normal (i.e. the network is not congested), so that the data transmission duration is ideal, along with the progress of data transmission, when abnormal time information is recorded, the actual duration of data transmission can be determined, then the transmission progress of a data transmission process is determined based on the proportion of the actual duration to the estimated data transmission duration, and further, the first data transmitted before the abnormal time information is determined according to the transmission progress. In another implementation manner, after obtaining the abnormal time information, the embodiment can obtain the actual time of data transmission, and then obtain the transmission progress of the data transmission process based on the data transmission speed and the actual time of data transmission, so that it can be determined which data are already transmitted and which data are not already transmitted in the data transmission process. Therefore, the present embodiment determines missing data based on the target transmission amount of the data transmission process and the transmitted first data, the missing data being the target transmission amount minus the transmitted first data. The embodiment determines that missing data is beneficial to realizing breakpoint continuous transmission in a subsequent step.
And step S300, when the transmission state is a normal state, controlling the data transmission process to continue transmitting the missing data based on an encryption protocol bandwidth.
When determining that the missing data is in the normal state, the embodiment controls the data transmission process to continue transmitting the missing data based on the encryption protocol bandwidth, thereby ensuring that the data which is not transmitted due to interruption can be transmitted to the data receiving end in time and ensuring the integrity of data transmission.
In one implementation manner, when the missing data is breakpoint continuous, the method includes the following steps:
step S301, monitoring the transmission state in real time, and sending a continuous transmission request to a data receiving end when the transmission state is monitored to be switched from an abnormal state to a normal state;
step S302, receiving confirmation information made by the data receiving end based on the continuous transmission request, acquiring the missing data according to the confirmation information, and continuing to transmit the missing data based on the encryption protocol bandwidth.
Specifically, the terminal of this embodiment monitors the transmission state in real time, and when it is monitored that the transmission state is switched from an abnormal state to a normal state, sends a continuous transmission request to the data receiving end. The retransmission request is used to reflect the intention that the data transmission needs to be continued at this time. After receiving the continuous transmission request, the data receiving end can firstly verify the continuous transmission request, and the purpose of verification is to determine whether the continuous transmission request is a request sent by the data sending end for continuing data transmission so as to be confused with the requests sent by other terminals. In addition, after the continuous transmission request is verified, the embodiment confirms the continuous transmission request and feeds back confirmation information to the data sending end so as to inform the data sending end of continuous transmission of data. In addition, in another implementation manner, when the data receiving end sends a continuous transmission request, the continuous transmission request may carry a data identifier, where the data identifier is an identifier of missing data, that is, an identifier of data that needs to be transmitted by the data transmission process. After the data receiving end receives the continuous transmission request, the continuous transmission request is analyzed to obtain the data identification, and based on the data identification, the data receiving end can determine that the data needing continuous transmission at the moment is data which is not transmitted because of interruption, and based on the data identification, the data receiving end feeds back confirmation information to the data sending end so as to inform the data sending end of continuous transmission of the data. Then, the embodiment may acquire the missing data according to the acknowledgement information, and continue to transmit the missing data based on the encryption protocol bandwidth.
In one implementation manner, when the missing data is transmitted, the embodiment first obtains broken bit data in the missing data, where the broken bit data is data of a breakpoint position corresponding to the abnormal moment information, that is, a position where the data transmission process is interrupted. Then, the embodiment transmits the broken bit data to a data receiving end based on the encryption protocol bandwidth, and controls the data receiving end to compare the broken bit data with the transmitted first data after receiving the broken bit data, so as to determine whether repeated data exists. The purpose of determining whether repeated data exists is to achieve seamless continuous transmission of the data, and avoid waste of bandwidth resources due to repeated data transmission. If there is duplicate data, the broken bit data is the data which has been transmitted to the data receiving end before, then the broken bit data is abandoned, and the data after the break point position is obtained from the missing data for transmission, thereby realizing seamless continuous transmission.
In one implementation, this embodiment also supports data out-of-order delivery. The present embodiment can record the position information of each data reflecting the position of each data in the entire data packet. In the data transmission stage, the data can be transmitted in a multithreading way without considering the sequence among the transmitted data, and the data receiving end can reconstruct according to the position information carried by each data, thereby obtaining complete data. Based on this, in this embodiment, when breakpoint continuous transmission is performed, the missing data may be subjected to segmentation processing to obtain a plurality of data fragments, where each data fragment corresponds to one piece of location information, and in this embodiment, the data fragments may be transmitted in a multithreading manner, and then the data receiving end may perform recombination according to the location information carried by each data fragment, so as to obtain complete missing data, and improve the efficiency of data transmission.
In another implementation manner, the embodiment may further acquire a network state in real time, and control the data transmission process to suspend data transmission when the network state is determined to be a congestion state, and control the data transmission process to resume data transmission when the network state is determined to be a allowance state, so as to perform data transmission based on different network states, and ensure the efficiency and the integrity of data transmission.
It can be seen that, in this embodiment, a transmission state of a data transmission process is first obtained, and when the transmission state is an abnormal state, abnormal time information is recorded, where the abnormal time information is used to reflect a time when the abnormal state occurs; determining first data transmitted by the data transmission process before the abnormal time information based on the abnormal time information, and determining missing data based on the transmitted first data, wherein the missing data is data which is not transmitted; and when the transmission state is a normal state, controlling the data transmission process to continue transmitting the missing data based on an encryption protocol bandwidth. The embodiment can realize breakpoint continuous transmission when the data transmission process is interrupted, so that the data receiving end can receive complete data, and the encryption protocol bandwidth is adopted, so that the abnormality of data transmission can be detected in real time, encryption transmission of the data can be realized, and the data safety is ensured.
