Abstract
The invention provides a kind of data error-free transmission processing method, comprise the steps: that A. receiving terminal receives data sending request; B. the data received are stored in spatial cache by receiving terminal; C. receiving terminal is by the data write local data file in spatial cache.The invention has the beneficial effects as follows that mass data can not cause loss because of bust this in the process transmitted, ensure the error free transmission of large data.
Description
Technical field
The present invention relates to data transmission method, particularly relate to data error-free transmission processing method.
Background technology
Due to the disequilibrium of Information Technology Development and the variation of business function, result in each office, multiple service software system is established for different business in the process that enterprises and institutions develop in informatization, each system data is separate, define information island, each system is implement resource integration, unified process is the direction of information system development, to the business datum of magnanimity be had to need zero defect transmission with mutual thus, due to the restriction of hardware device, mass data easily causes loss because of bust this in the process transmitted, how to ensure that the error free transmission of large data seems particularly urgent.
Summary of the invention
In order to solve the problems of the prior art, the invention provides a kind of data error-free transmission processing method.
The invention provides a kind of data error-free transmission processing method, comprise the steps:
A. receiving terminal receives data sending request;
B. the data received are stored in spatial cache by receiving terminal;
C. receiving terminal is by the data write local data file in spatial cache.
As a further improvement on the present invention, in described steps A, data sending request comprises data length, bag size, bag number, finally bag size, suspends bag number.
As a further improvement on the present invention, in described step B, also comprise the steps:
B1. receiving terminal is according to time-out bag number application spatial cache, and spatial cache size is that bag size * suspends bag number, if spatial cache application success, then performs B2 step, otherwise prompting low memory;
B2. receiving terminal sends data continuation transmission command to transmitting terminal, and parameter comprises data and sends original position;
B3. after transmitting terminal receives data continuation transmission command, extract data and send original position parameter, data pointer is moved to data and send original position, read the packet of the several number of time-out bag, circulate to receiving terminal and send data content;
B4. receiving terminal receives data content, and is copied in spatial cache by data content.
As a further improvement on the present invention, comprise the steps: in described step C
C1. receiving terminal judges whether that all data finish receiving, and as completed, then sends DTD order to transmitting terminal, and performs C2 step; As do not completed, then perform B2 step;
C2. all memory variables used in transmitting terminal release transmission.
As a further improvement on the present invention, comprise the steps: in described step B4
B41. checking whether spatial cache receives data, as received data, then performing B2 step; Otherwise send data re-transmitting order to transmitting terminal, parameter is the packet sequence number row do not received;
B42. transmitting terminal receives data re-transmitting order, then extract the packet sequence number row do not received, then perform B2 step.
The invention has the beneficial effects as follows: mass data can not cause loss because of bust this in the process transmitted, and ensures the error free transmission of large data.
Accompanying drawing explanation
Fig. 1 is method flow diagram of the present invention.
Fig. 2 is the method flow diagram of one embodiment of the invention.
Embodiment
As shown in Figure 1, the invention discloses a kind of data error-free transmission processing method, comprise step S1 to step S3, in step sl, receiving terminal receives data sending request.In step s 2, the data received are stored in spatial cache by receiving terminal.In step s3, receiving terminal is by the data write local data file in spatial cache.
As shown in Figure 2, as one embodiment of the invention, comprise step Q1 to step Q10.In step Q1, receiving terminal receives data sending request, and data sending request comprises data length, bag size, bag number, finally bag size, suspends bag number.In step Q2, set up spatial cache, and judge whether successful spatial cache is set up, if success, performs Q3 step, otherwise prompting low memory; Receiving terminal is according to time-out bag number application spatial cache, and spatial cache size is that bag size * suspends bag number.In step Q3, receiving terminal sends data to transmitting terminal and continues transmission command, and parameter comprises data and sends original position.In step q 4, transmitting terminal extracts data and sends original position parameter after receiving data continuation transmission command, data pointer is moved to data and sends original position, reads the packet of the several number of time-out bag, circulates to receiving terminal and sends data content.In step Q5, receiving terminal receives data content, and is copied in spatial cache by data content.In step Q6, checking whether spatial cache receives data, as received data, then performing Q3 step; Otherwise send data re-transmitting order to transmitting terminal, parameter is the packet sequence number row do not received.In step Q7, transmitting terminal receives data re-transmitting order, then extract the packet sequence number row do not received, then perform Q3 step.Perform step Q6 and step Q8 after execution step Q5 simultaneously.In step Q8, receiving terminal is by the data write local data file in spatial cache.In step Q9, receiving terminal judges whether that all data finish receiving, and as completed, then sends DTD order to transmitting terminal, and performs Q10 step; As do not completed, then perform Q3 step.In step Q10, all memory variables used during transmitting terminal release sends.
Mass data can not cause loss because of bust this in the process transmitted, and ensures the error free transmission of large data.
Above content is in conjunction with concrete preferred implementation further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, some simple deduction or replace can also be made, all should be considered as belonging to protection scope of the present invention.
