Technical field
The present invention relates to a kind of datagram network transmission method, particularly relate to a kind of applicable forward error correction and encrypt the datagram network transmission method of application.
Background technology
Forward error correction technique is for improving the reliability of Internet Transmission, and encryption technology is for guaranteeing the confidentiality of transmission.
During the major part of these two kinds of technology realizes, requirement will need data to be processed to be divided into isometric.Yet in reality, the Internet Transmission of form of datagrams (for example udp agreement), it is short that message has length to have.Therefore when processing, the inadequate data message for length, need to fill invalid data.For each data message, carry out the filling of invalid data at transmitting terminal, at receiving terminal, invalid data is got rid of, make whole Internet Transmission execution efficiency lower, the validity of transmission data is also lower.
Summary of the invention
For above-mentioned the deficiencies in the prior art, the purpose of this invention is to provide a kind of applicable forward error correction and encrypt the datagram network transmission method of application, reduce or eliminate the filling of invalid data, and then reduced or eliminated the processing for invalid data, improve efficiency of transmission.
Technical scheme of the present invention is such: the datagram network transmission method of a kind of applicable forward error correction and encryption application, comprise that transmitting terminal carries out preliminary treatment, transmission, receiving terminal to receiving the reverse preliminary treatment of data to data to be sent, it is characterized in that: described transmitting terminal carries out before preliminary treatment by some raw data packets splicings and by the equal length Data Segmentation data to be sent, and the isometric packet that described receiving terminal will receive after to the reverse preliminary treatment that receives data splices and extracts raw data packets; Described preliminary treatment comprises at least one generation in forward error correction and encryption, says that reverse preliminary treatment comprises at least one that process in forward error correction and decryption processing.
In a specific embodiment of the present invention, when described transmitting terminal is pressed the equal length Data Segmentation, add invalid data when the end data length is not enough and reach tentation data length.
In order to reduce at data sending terminal owing to waiting for that raw data packets reaches the time delay that certain-length causes, in another specific embodiment of the present invention, described transmitting terminal starts timing while obtaining first raw data packets, after certain hour, to the splicing of the raw data packets obtained and by the equal length Data Segmentation.
In another specific embodiment of the present invention, described transmitting terminal carries out adding protocol header after preliminary treatment to data to be sent, and described protocol header comprises splicing and the carve information of raw data packets.
Technical scheme provided by the present invention, cut apart after packets splicing will be a plurality of to be sent again, makes to comprise as much as possible valid data in the packet after single cutting apart, and avoids filling a large amount of invalid datas and cause network transmission efficiency low.Realized that zero of invalid data adds or a small amount of the interpolation, reduced the invalid data processing time, utilized the time to control and avoid splicing to wait for the time delay caused, raised the efficiency.Simultaneously, this processing scheme can not affect follow-up error correction and encryption, guarantees reliability and the fail safe of transfer of data.
The accompanying drawing explanation
Fig. 1 is flow chart of data processing schematic diagram of the present invention.
Embodiment
Below in conjunction with embodiment, the invention will be further described, but not as a limitation of the invention.
Refer to Fig. 1, at the transmitting terminal of data, the length of data to be sent differs, and has length to have short.Adopt the packing function that a plurality of raw data packets are again spliced and cut apart by designated length, generate new packet.Then a plurality of shorter raw data packets can first be spliced and be cut apart, and a longer raw data packets directly is divided into a plurality of new data packets again.When a raw data packets reaches, it is inserted to a upper new packet that does not reach designated length, if this raw data packets is longer, in the time of can't be inserted new packet fully, by a newly-built new packet, raw data packets is not inserted to part and put into this packet.Each raw data packets is carried out successively, and in last packet, data length is not filled invalid data as reached designated length, then generates forward error correction and is encrypted.In application in real time, raw data packets is to generate in real time.If the length of the not enough appointment of the raw data packets of current accumulation, need to wait for the arrival of more raw data packets, always bring uncontrollable time delay.For this situation, at transmitting terminal, timer is set, wait at most certain hour minute steamed sandwich again.When overtime generation, the raw data packets of accumulation is integrated in new packet, even not enough designated length.When processing, the part of not enough length still, according to existing mode, is filled invalid data; And data exceed designated length part and are postponed by force to next time circulation and spliced and cut apart.Under this kind of situation, though adopt this programme can not eliminate the invalid data of filling, can effectively reduce the invalid data of filling.After carrying out forward error correction and encryption, packet adds new protocol header, and this protocol header has been described in the packet after cuts apart again, and raw data packets is positioned at those positions, and whether raw data packets is truncated etc.In order to be applicable to forward error correction, also indicated transmission window slogan and the interior numbering of window at notebook data bag place in new protocol header.
At data receiver, the data of reception are through processing, such as carrying out error correction, deciphering etc.According to the description of new protocol header, isolate raw data packets.Detailed process is according to the protocol header content, to record window number and the interior numbering of window of current data packet after receiving terminal reception packet.Whether the next packet of receiving for judgement is the sequence number continuity, thereby whether packet loss is arranged between learning, when packet loss occurs, stack is emptied.Here stack is to wait the raw data packets segment of piecing together out for storing those, once packet loss occurs, the segment before can't have been recovered certainly, therefore abandon.In stack, each fragment of raw data packets is pressed into until then the raw data packets end is popped and be spliced into complete raw data packets.While reading the raw data packets segment in stack, carry out two integrality judgements, if 1. stack is empty, and current fragment is mid portion or the afterbody of certain raw data packets, and this raw data packets can't be recovered, and directly returns, and abandons current fragment; 2. stack the inside is head or the mid portion of a raw data packets, and new stacked fragment be another raw data packets part or all, the afterbody of first raw data packets is lost and can't be recovered, and empties stack.Can get rid of the loss of the raw data packets fragment caused after the Internet Transmission packet loss by these two inspections, abandon the raw data packets that can't be resumed.
